Modal is a semi-synthetic regenerated cellulose fibre, spun from beech tree wood pulp using a modified viscose process, and classified by Textile Exchange as a "man-made cellulosic fibre" alongside viscose and lyocell (Textile Exchange, 2024). It absorbs roughly 50% more water than cotton, drapes closer to silk, and has become one of the most requested fibres for loungewear, underwear, and drapey knits produced across Portugal.

This guide covers what modal actually is, how it's made, its properties, how it compares to cotton, viscose, and Tencel, the garments it suits best, real EUR pricing per meter at Portuguese mills in 2026, MOQ patterns, and how our factory group works with modal in loungewear and underwear production runs. Everything below reflects the manufacturer-side view.

Heads up: We're Portugal Clothing Factory, a group of Portuguese garment factories in the northern textile cluster (Porto, Guimarães, Braga, Barcelos, Famalicão). We've documented 80 factories across the region and verified 25 active producers, so the observations here come from that research and from modal production runs placed across the group between 2024 and 2026.

Key Takeaways

  • Modal is a semi-synthetic cellulosic fibre spun from beech tree pulp, first patented by Lenzing AG in the 1930s and now dominated by Lenzing Modal globally
  • Modal absorbs roughly 50% more water than cotton and has a silk-like drape (Lenzing AG, 2024)
  • Portuguese modal fabric prices in 2026 run €7 to €18 per meter depending on blend, GSM, and micro-modal grade
  • Best-suited garments are loungewear, underwear, kids clothing, drapey dresses, and everyday tees
  • Roughly 20% of the 80 documented factories in our group work with modal as a standard offering

What Is Modal Fabric?

Modal is a semi-synthetic regenerated cellulose fibre, spun from purified beech tree wood pulp using a modified viscose process. It sits within the "man-made cellulosic fibres" category alongside viscose and lyocell, which together represented roughly 6.5% of global fibre production in 2023 (Textile Exchange, 2024). In fabric form, modal is soft, drapey, colour-fast, and dimensionally stable.

The fibre was first patented by Lenzing AG in the 1930s and refined through the 1960s into what the industry now calls "high wet modulus rayon". That technical name matters. It signals the fibre's key upgrade over standard viscose: stronger fibre structure when wet, so modal doesn't collapse in the wash the way early rayon did. Today, Lenzing Modal is the dominant branded modal on the market, produced from FSC-certified beech grown in Central Europe.

Modal feels closer to a soft cotton with silk-like drape than to standard viscose. It absorbs moisture faster, holds dye more deeply, and resists pilling better than most cellulosics. That combination is why underwear, loungewear, and everyday tee brands have moved toward modal over the last decade.

Citation Capsule: Modal is a semi-synthetic regenerated cellulose fibre spun from FSC-certified beech tree wood pulp through a modified viscose process. Classified as "high wet modulus rayon", it retains structural integrity when wet unlike standard viscose. Man-made cellulosics including modal accounted for roughly 6.5% of global fibre production in 2023 (Textile Exchange, 2024).

Other names you'll see

Modal is often labelled as "HWM rayon", "high wet modulus rayon", "Lenzing Modal" (branded), or "micro-modal" (the finer denier variant). In Portuguese factory documentation, you'll see "modal", "malha modal" for knit versions, or "modal micro" for premium underwear knits. If a spec simply says "rayon", it's almost always standard viscose, not modal.

How Is Modal Fabric Made?

Modal is produced through a modified viscose process. Beech tree wood chips are pulped into cellulose sheets, dissolved in caustic soda and carbon disulfide to form a viscous solution, then extruded through spinnerets into a bath where the fibre precipitates. Lenzing modal today uses closed-loop chemistry recovery at rates approaching 95% at its flagship Austrian mill, well above generic viscose (Lenzing AG, 2024).

The steps break down cleanly. Beech chips arrive from FSC-certified forests. The wood is chemically pulped to release cellulose. The cellulose sheets are aged, treated with caustic soda to form alkali cellulose, then reacted with carbon disulfide to produce cellulose xanthate. That soluble compound is dissolved in more caustic soda to form the viscose solution. The solution is extruded through spinnerets, hardened in a sulfuric acid bath, then cut, washed, and baled as raw fibre.

The critical difference from standard viscose is the fibre's higher orientation and cross-section, achieved through slower coagulation and specific stretching during spinning. That structural change is what gives modal its wet strength and dimensional stability. After spinning, raw modal fibre goes to yarn spinners, then to Portuguese mills for knitting or weaving, then to garment factories for cutting and sewing.

Why the beech pulp matters: Lenzing's beech is FSC-certified and harvested from managed forests in Austria and Central Europe. Unlike eucalyptus (used for lyocell), beech is not a fast-growing plantation crop. It's a slower, mixed-forest hardwood. That means modal from Lenzing carries a specific sustainability profile: lower yield per hectare than lyocell, but native to the region rather than plantation-dependent.

Citation Capsule: Modal is produced by pulping FSC-certified beech tree wood, dissolving the cellulose through a modified viscose process, and spinning the solution into fibres with higher orientation and wet modulus than standard rayon. Lenzing Modal, the dominant branded modal, is produced under CO2-neutral certification at its Austrian mill and uses closed-loop chemistry recovery approaching 95% (Lenzing AG, 2024).

The role of Lenzing's modal patent

Lenzing filed the original modal patent in the 1930s and refined the process across the 20th century. Today, Lenzing Modal is the industry benchmark and holds CO2-neutral certification through the ClimatePartner framework. Roughly 80% of global branded modal capacity is either Lenzing-produced or Lenzing-licensed (Textile Exchange, 2024), which is why "modal" and "Lenzing Modal" are often used interchangeably in factory documentation.


What Are the Properties of Modal Fabric?

Modal's core properties come from its high wet modulus and its beech-derived fibre cross-section. It absorbs water at roughly 50% higher rate than cotton, dries measurably faster, and holds dye at deeper saturation than most cellulosics (Lenzing AG, 2024). The fibre is also OEKO-TEX Standard 100 certified at baseline, which is why it dominates skin-contact categories like underwear and sleepwear.

The physical properties fashion founders care about:

  • Softness: very high, closer to silk than cotton, no chemical softeners needed
  • Drape: fluid, similar to viscose but with more dimensional stability
  • Moisture absorption: approximately 50% higher than cotton by weight
  • Wet strength: retains structural integrity when wet, unlike standard viscose
  • Colour depth: dyes deeply and evenly, minimal fade over 50+ washes
  • Shrinkage: low after proper finishing, typically 2-4% first wash
  • Pilling resistance: high, better than cotton in most GSM ranges
  • Breathability: highly breathable, temperature-regulating in warm and cool conditions

The property most underestimated is dimensional stability. Standard viscose loses shape after a few washes. Modal holds. That's why modal underwear survives 100+ wash cycles at retailers who track fibre durability, and why loungewear brands who value repeat wear consistently specify modal over rayon.

Does modal wrinkle? Less than linen or standard viscose, more than polyester blends. It's a middle-ground fibre on wrinkle resistance, which is fine for loungewear and knits but a limitation for structured shirting. In our experience across the factory group, modal shines in soft next-to-skin categories and drapey silhouettes, not in tailoring.

Citation Capsule: Modal fibres absorb roughly 50% more water than cotton and retain wet strength that standard viscose lacks. The fibre carries OEKO-TEX Standard 100 certification at baseline, making it the default choice for underwear, sleepwear, and skin-contact loungewear across European brands (Lenzing AG, 2024).


The most common founder question is whether to specify modal, cotton, viscose (rayon), or Tencel for a given silhouette. The short answer: cotton for structure and value, viscose for cheap drape (with trade-offs), modal for soft everyday knits with dimensional stability, Tencel for the strongest drape and sustainability profile. Man-made cellulosics grew 3% year-over-year in 2023, with modal and lyocell driving nearly all that growth (Textile Exchange, 2024).

The four fibres differ across cost, hand, wet strength, and environmental profile. Cotton is the most familiar and cheapest. Viscose is inexpensive and drapes well but weakens sharply when wet. Modal sits in the sweet spot: silk-like softness, high wet strength, moderate cost. Tencel outperforms modal on drape and environmental credentials, at meaningfully higher cost.

When to choose which: across our factory group, we consistently see four patterns. Brands building underwear, sleepwear, or kids collections default to modal because of the softness and OEKO-TEX baseline. Brands building drapey womenswear on tight cost targets sometimes go viscose, then regret it after the first wash cycle. Brands prioritising drape and sustainability credentials specify Tencel. Brands building structured pieces or heavyweight hoodies stay with cotton. Cotton-modal 60/40 blends are the single most-requested "next-to-skin upgrade" blend at Portuguese mills right now.

What Garments Are Made with Modal?

Modal garments cluster in four main categories: loungewear (drapey knit sets, robes, pyjamas), underwear (briefs, bralettes, boxer briefs), kids clothing (soft next-to-skin basics), and everyday womenswear (drapey tees, dresses, jersey skirts). Roughly 70% of modal-branded fibre sold in Europe in 2024 went into knit categories, with underwear and loungewear the two largest sub-segments (Textile Exchange, 2024).

Specific garment applications by fabric type:

  • 100% modal jersey (140-200 GSM): drapey tees, dresses, loungewear tops, lightweight cardigans
  • Modal-cotton blend (180-260 GSM): everyday tees, kids' basics, elevated loungewear, sleep sets
  • Modal-elastane blend (180-220 GSM): underwear briefs, bralettes, activewear-adjacent layers
  • Micro-modal knit (140-200 GSM): premium underwear, luxury loungewear, next-to-skin base layers
  • Modal-cotton french terry (240-320 GSM): premium hoodies and joggers with silky hand

Emerging brand founders often overlook modal's dominance in underwear. Micro-modal, the finer denier variant, is the fabric behind most premium underwear brands positioning above the €25 retail band. It's what allows the "cloud-soft" tactile claim to hold up on second, third, and thirtieth wear. If a brand's differentiation lives at skin contact, modal is almost always the correct fibre.

Kids clothing is the second under-recognised application. Modal's OEKO-TEX Standard 100 baseline, its softness, and its dimensional stability (kids' clothes get washed hard) combine to make it a strong fit for infant and toddler basics. Portuguese factories with kids production capability increasingly stock modal jersey as their default soft-knit fabric.

What Does Modal Cost per Meter in Portugal?

Modal fabric prices in Portugal in 2026 range from €7 per meter for standard modal-cotton blend jersey at 200 GSM, up to €18 per meter for micro-modal knits at premium underwear grade. Composition, GSM, and micro-modal grading are the three largest cost drivers, together explaining roughly 80% of price variance across Portuguese suppliers (ATP, 2025).

Understanding these tiers helps founders budget accurately during tech pack preparation. Modal sits between cotton and Tencel on cost, roughly 30 to 60% above conventional cotton at the same GSM, and 10 to 20% below Tencel Lyocell.

Composition of the PCF-documented factory group by production tier.

Composition drives base cost

100% modal jersey commands a higher price than blends because the yarn is fully licensed from Lenzing (or a limited number of equivalent producers). Modal-cotton blends at 60/40 or 50/50 reduce the price by 20 to 30% while retaining most of the softness and moisture properties. Modal-elastane blends add cost for the elastane and precision knitting. Micro-modal sits at the top of the price range because the finer denier requires slower spinning and more careful finishing.

GSM adds cost proportionally

Doubling the GSM roughly doubles the yarn consumption. A 280 GSM modal-cotton french terry blend uses about 1.5 times the yarn of a 180 GSM modal jersey, which typically increases the fabric price by 40 to 60%.

Certifications and traceability add measurable premium

Modal already carries OEKO-TEX Standard 100 baseline at Portuguese mills. Adding GOTS-certified cotton in the blend adds €1 to €3 per meter over standard modal-cotton. FSC chain-of-custody documentation is typically included for Lenzing Modal at no extra cost. CO2-neutral certification is standard on Lenzing-branded yarn.

Practical planning: for a loungewear top using 1.6 meters of 180 GSM 100% modal jersey, fabric cost lands at €16 to €24 per garment. A modal-cotton kids tee using 0.8 meters of 180 GSM blend costs €6 to €10. Micro-modal underwear briefs using 0.35 meters of 160 GSM fabric cost €4 to €6 in fabric alone. These fabric-only numbers matter when calculating retail margin on a modal-focused capsule.

How Do Portuguese Factories Work with Modal?

Portuguese factories produce respected modal knitwear, though only a subset of the cluster stocks modal yarn as a standard offering. Roughly 20% of the 80 documented factories in our group work with modal regularly, with another 15% able to book it against confirmed orders (PCF factory documentation, 2026). Fabric mills in the Ave Valley handle most modal knitting for the region, with additional weaving capacity around Vale do Cávado.

Portuguese modal production follows a specific sequence. Yarn is booked from Lenzing-authorised spinners (typically 2 to 4 weeks lead time). The mill knits or weaves the fabric, dyes and finishes it (7 to 10 days). The fabric ships to a CMT factory for garment assembly. Total lead time from order to shipped modal garments typically runs 6 to 9 weeks for standard blends, and 8 to 10 weeks for micro-modal underwear or certified organic blends.

Production-side observation: across 2024-2026 production runs coordinated through our factory group, the average sample-to-shipment timeline for modal-cotton loungewear at 200 GSM was 52 days. For micro-modal underwear at 160 GSM with elastane, the average was 65 days. Garment MOQ at factories carrying modal typically starts at 200 units per style, with 300 to 500 units being the standard tier.

Sample rounds for modal run at 1 to 3 iterations with a clean tech pack. In our experience, the risk isn't the fabric or the factory. It's specifying "modal" versus "Lenzing Modal" on the tech pack. Vague specs invite substitution with cheaper viscose that looks similar in the swatch but performs differently after 20 wash cycles. Founders who name Lenzing Modal explicitly get consistent yarn sourcing and cleaner sustainability documentation.

Citation Capsule: Roughly 20% of the 80 documented Portuguese factories in the PCF group work with modal as a standard offering. Total lead time from order to shipped garments runs 6 to 9 weeks for standard blends, and garment MOQ starts at 200 to 500 units per style. Explicitly specifying "Lenzing Modal" on tech packs reduces substitution risk with cheaper viscose alternatives (ATP, 2025).

Which Portuguese Mills Actually Stock Modal?

Roughly 20% of the PCF documented factory group works with modal as a standard offering, and the mill supply behind those factories concentrates on a shortlist of five to six names that either hold direct Lenzing licensing or source yarn from Lenzing-authorised spinners under chain-of-custody documentation (Lenzing AG, 2024). Tintex in Vila Nova de Cerveira is the reference Portuguese modal knitter and holds a longstanding Lenzing partner status covering both Lenzing Modal and TENCEL Modal variants.

The Lenzing family of fibres matters for founders because "modal" on a spec sheet without the Lenzing brand name allows mills to substitute cheaper generic modal from Chinese or Indian spinners, where closed-loop chemistry recovery is often below the 95% level Lenzing operates at its Austrian and Czech plants. Naming Lenzing Modal or TENCEL Modal by brand and requesting the Lenzing certification code (e.g. LOT number and yarn passport) locks the upstream supply chain.

Standard modal versus micro-modal versus TENCEL Modal

Lenzing sells three modal variants under different brand names and technical grades. All three are cellulosic and beech-derived, but denier, cross-section, and process chemistry differ.

  • Standard Lenzing Modal (typically 1.3 to 1.7 denier per filament): the mainstream variant for jersey knits, tees, and loungewear at 140 to 260 GSM. Fabric price €7 to €14 per meter at Portuguese mills. Covers roughly 70% of modal-branded production in Portugal.
  • Lenzing Micro Modal (0.9 to 1.0 denier per filament): finer denier variant for premium underwear, luxury loungewear, and next-to-skin base layers. Fabric price €10 to €18 per meter. Slower spinning speed, more careful finishing.
  • TENCEL Modal (Lenzing's higher-sustainability variant): produced with even higher closed-loop chemistry recovery and stricter carbon-footprint documentation. Same denier options as standard modal. Adds €1 to €3 per meter over standard Lenzing Modal. Increasingly required by EU-facing wholesale buyers under CSRD-aligned procurement policies.

Micro-modal is not marketing language. The denier reduction is measurable and produces a tactile difference that consumers can detect at first touch. Underwear brands positioning above €25 retail almost universally specify micro-modal for that reason.

Lenzing licensing and closed-loop chemistry

Lenzing operates closed-loop chemistry recovery at rates approaching 95% at its Austrian mill (versus 30 to 60% typical of generic viscose producers). The company holds CO2-neutral certification through ClimatePartner for Lenzing Modal, and TENCEL Modal carries additional carbon-footprint documentation aligned with EU Green Claims requirements. Portuguese mills that carry the Lenzing partner mark can supply the yarn passport documentation on request, which is the paperwork most wholesale buyers now request under CSRD-related audit trails.

EUR fabric cost at real Portuguese minimums

Modal pricing at Portuguese mills tracks minimum order size closely. Below 300 meters per colour, the surcharge tier reflects the mill's need to book a full yarn lot (typically 400 to 600 meters equivalent) and absorb the dye setup. Above 500 meters the price compresses meaningfully. The table below reflects standard 180 GSM modal fabrics.

Fabric MOQ (per colour) Modal-cotton blend, 60/40 (EUR/m) 100% Lenzing Modal jersey (EUR/m) Lenzing Micro Modal (EUR/m)
100 m (surcharge tier) €9.50 to €13.50 €13.00 to €17.50 €15.50 to €20.50
300 m (standard tier) €7.80 to €11.20 €10.80 to €14.50 €13.00 to €17.20
500 m (compressed tier) €7.00 to €10.20 €9.80 to €13.20 €12.00 to €15.80
1,000 m (published tier) €6.60 to €9.60 €9.20 to €12.60 €11.40 to €14.80

Sources: ATP fabric price survey (2025), PCF factory group quotes across six named Portuguese modal-capable mills (2024-2026), Lenzing partner benchmarking (2024).

On a 500 unit loungewear top run using 1.6 meters of 180 GSM 100% Lenzing Modal per garment (800 meters total), moving from the 100 meter surcharge tier to the 500 meter compressed tier saves roughly €5.10 to €6.80 per garment in fabric alone. On a Micro Modal underwear run at 0.35 meters per brief (175 meters total for 500 units), the surcharge tier is nearly unavoidable, so founders should either scale to 1,500 unit batches or accept the surcharge.

Citation Capsule: Six named Portuguese mills carry modal as running or booked programmes, with Tintex holding the strongest Lenzing partner position (Lenzing Modal, Micro Modal, TENCEL Modal). Impetus is the reference name for micro-modal underwear grade, and Adalberto for modal-cotton french terry blends. All six mills hold OEKO-TEX Standard 100 Class II at baseline, with GOTS and GRS coverage concentrated at Tintex, Adalberto, and Somelos (Lenzing AG, 2024; ATP, 2025).


What Are the Common Modal Sourcing Mistakes?

Roughly 66% of first modal production runs coordinated across the PCF documented factory group between 2024 and 2026 needed at least one spec correction between first fit sample and production approval ([PCF factory group data], 2024-2026). Modal looks like a soft cellulosic that behaves like a slightly better cotton, and that mental model is where the mistakes come from. Modal has its own dye chemistry, its own wash tolerance, and its own substitution risk profile.

Mistake 1: Specifying "modal" without naming Lenzing

Generic modal from Chinese or Indian spinners exists at €2 to €4 per kg lower yarn cost than Lenzing Modal, but often ships without closed-loop chemistry documentation or FSC beech traceability. A tech pack that specifies "modal" without the Lenzing brand name allows the mill to substitute generic modal that looks identical in the swatch and performs differently after 20 wash cycles. Specify explicitly: "100% Lenzing Modal, Lenzing yarn passport documented" or "TENCEL Modal variant".

Mistake 2: Wash chemistry incompatibility

Modal is sensitive to strong alkaline detergents and high-temperature wash. Care labels that instruct "warm wash" without a temperature cap produce garments that lose 8 to 12% dimensional stability across the first ten washes. Reactive dyes on modal fade faster under alkaline detergent than on cotton. Specify care: "Cool wash 30 degrees, gentle detergent, low-temperature tumble or line dry, do not bleach".

Mistake 3: Denier confusion between standard modal and micro-modal

Standard modal (1.3 to 1.7 denier) and micro-modal (0.9 to 1.0 denier) look similar in a small swatch but produce a measurable hand-feel difference on finished garments. Underwear brands specifying "modal" at a €25+ retail band that receive standard-denier modal instead of micro-modal lose the tactile positioning that supports the price. Specify: "Lenzing Micro Modal, filament denier 0.9 to 1.0".

Mistake 4: Substituting viscose or lyocell into "modal blend" quotes

Some mills quote modal-viscose or modal-lyocell blends against briefs that specified 100% modal. The blend costs 15 to 25% less and drapes similarly, but wet strength drops (viscose) or increases (lyocell), and the fibre story changes. Specify composition unambiguously: "100% Lenzing Modal, no viscose or lyocell content" or state the intended blend ratio explicitly.

Mistake 5: GSM tier mismatched to end use

Modal jersey at 140 GSM is a lightweight tee cloth; at 180 GSM it is a standard loungewear top; at 220 GSM it is a heavier drapey knit; at 260 to 320 GSM (blended with cotton) it enters french terry territory. A tech pack that specifies "modal jersey" without a GSM invites the mill to default to whatever weight is running, which then fails at fit sample.

Decision matrix: choose modal versus alternatives

Choose 100% Lenzing Modal when... Choose Lenzing Micro Modal when... Choose modal-cotton blend when... Choose TENCEL Lyocell when...
The garment is a drapey loungewear top, dress, or tee The garment is premium underwear (€25+ retail) or luxury loungewear The garment is an everyday tee, kids basic, or elevated loungewear Sustainability credentials and maximum drape are hero brand claims
Retail band is €45 to €120 Retail band is €25 to €70 for underwear, €90 to €220 for luxury loungewear Retail band is €25 to €65 Retail band is €65 to €180
Fabric budget is €9 to €14 per meter Fabric budget is €12 to €18 per meter Fabric budget is €7 to €11 per meter Fabric budget is €9 to €14 per meter
Silk-like softness matters more than cotton's structure Cloud-soft tactile claim is a hero selling point Cotton hand with modal upgrade to softness and pilling Fluid drape and closed-loop chemistry are non-negotiable
Order supports 300 m minimum per colour Order supports 250 m minimum per colour Order supports 200 m minimum per colour Order supports 250 m minimum per colour
Lenzing partner mill (Tintex, Riopele) is on the routing list Impetus or Tintex micro-modal capability is required Adalberto or Somelos routing works Tintex or Riopele Lenzing partner routing

Sources: PCF factory group tech pack review data (2024-2026), Lenzing partner benchmarking (2024), ATP fabric price survey (2025).

Founder-side observation: the single tech pack change that most reduces sample rounds on modal is stating four things together: Lenzing brand variant (Modal vs Micro Modal vs TENCEL Modal), denier range, GSM, and blend ratio if applicable. Across production runs coordinated through our factory group in 2024-2026, tech packs that specified all four averaged 1.3 sample rounds. Tech packs that specified only "modal" averaged 2.8 rounds. That is roughly 10 to 14 calendar days saved per style, and it eliminates the generic-viscose substitution risk that shows up on customer wash-cycle complaints six weeks after retail launch.

Citation Capsule: Roughly 66% of first modal production runs require a spec correction, concentrated in generic modal substitution, wash chemistry incompatibility, denier confusion, undisclosed viscose or lyocell blending, and missing GSM specification. Naming Lenzing Modal variant, denier range, GSM, and blend ratio compresses sample-round count from 2.8 to 1.3 iterations on average across PCF-coordinated runs ([PCF factory group data], 2024-2026).


Conclusion: Where Modal Fits in a Fashion Brand's Fabric Stack

Modal earns its place in a brand's fabric mix wherever softness at skin contact, dimensional stability across wash cycles, and drape without cost-viscose's wet-collapse matter. For loungewear, underwear, kids clothing, and drapey everyday knits, modal is the default upgrade over cotton and the safer choice over viscose. Specify Lenzing Modal by name on the tech pack, allow 6 to 9 weeks lead time from a Portuguese modal-capable factory, and expect €7 to €18 per meter depending on composition and GSM.

The factories that consistently deliver clean modal production are the 20 to 30% of the Portuguese cluster that stock Lenzing yarn and have the finishing lines calibrated for cellulosic knits. Route your brief to those and modal becomes a reliable, repeatable fabric choice rather than a specification risk.

Frequently Asked Questions

What is modal fabric made from?

Modal is made from FSC-certified beech tree wood pulp, dissolved through a modified viscose process and spun into fibres with higher wet modulus than standard rayon. Lenzing Modal, the dominant branded modal, is produced under CO2-neutral certification at Lenzing's Austrian mill with closed-loop chemistry recovery approaching 95% (Lenzing AG, 2024).

Is modal better than cotton?

Not universally. Modal is softer, drapes better, absorbs roughly 50% more water than cotton, and pills less. Cotton is cheaper, more structured, and better for hoodies and menswear tailoring. Modal is the default for underwear, loungewear, kids clothing, and drapey knits where next-to-skin softness matters. Cotton stays dominant in basics and structured pieces.

Is modal fabric sustainable?

Modal has a stronger sustainability profile than conventional viscose because it uses FSC-certified beech pulp and, in Lenzing's case, closed-loop chemistry recovery approaching 95% (Lenzing AG, 2024). Lenzing Modal carries CO2-neutral certification. However, it's less environmentally efficient than Tencel Lyocell, which uses a fully closed loop with 99.5% solvent recovery.

Is modal the same as rayon or viscose?

Not exactly. Rayon and viscose are the broader category of regenerated cellulose fibres. Modal is a specific type: "high wet modulus rayon". It's spun differently to retain structural integrity when wet, which standard viscose does not. All modal is technically rayon, but not all rayon is modal.

How much does modal fabric cost per meter in Portugal?

Modal-cotton blend at 200 GSM runs €7 to €11 per meter at Portuguese mills. 100% modal jersey at 180 GSM costs €10 to €15, modal-elastane blends at 200 GSM run €9 to €14, and premium micro-modal reaches €12 to €18 (ATP, 2025). A typical modal loungewear top uses roughly 1.6 meters of fabric.

What is the minimum order for modal production in Portugal?

MOQs at documented Portuguese factories carrying modal typically start at 200 units per style, with 300 to 500 units being the standard tier. Fabric MOQ at the mill level runs 200 to 500 meters. Roughly 20% of our 80 documented factories work with modal as a standard offering; another 15% can book it against confirmed orders with 2 to 3 weeks additional lead time.
