Modal Yarn: The Complete Guide for Knitwear and Apparel Brands

Modal yarn is everywhere in premium knitwear — from luxury loungewear to high-end T-shirts and intimate apparel. But if you're an apparel brand considering modal for your next collection, you need more than the marketing bullet points. You need to understand what modal actually delivers in production, how it compares to cotton and lyocell, and what to watch for when sourcing modal yarn from a manufacturer.

At LongLu Materials, we produce modal yarn for international brands across South Asia and the Middle East. This guide shares what we've learned from the factory floor — from fiber selection to final fabric performance.

1. What Is Modal Fiber — And Why It's Different

Origin and Manufacturing

Modal is a type of rayon — a regenerated cellulose fiber — made from beechwood pulp. The wood is harvested from sustainably managed forests, primarily in Europe. The pulp is processed through a spinning bath to create soft, fine fibers that are then cut into staple lengths for yarn spinning.

What distinguishes modal from standard viscose rayon is the wet spinning process. Modal uses a modified viscose process that produces fibers with higher wet strength, better dimensional stability, and a characteristically silky hand-feel. Lenzing AG's TENCEL™ Modal is the most recognized brand, but generic modal fibers are also produced by several manufacturers globally.

Key Fiber Properties

Property	Modal	Cotton	Lyocell
Dry Tenacity (cN/dtex)	3.4 – 3.6	2.5 – 3.5	4.0 – 4.2
Wet Tenacity	2.0 – 2.2	2.8 – 3.5	3.4 – 3.8
Elongation at Break (%)	13 – 15	6 – 8	14 – 16
Moisture Regain (%)	12 – 13	7 – 8	11 – 12
Softness Rating (1-10)	9	6	8
Drape Rating (1-10)	9	5	8
Pilling Resistance	Moderate	Good	Good
Biodegradability	Full	Full	Full

The numbers tell a clear story: modal matches lyocell on softness and drape, outperforms cotton on moisture management, but gives up some wet strength and pilling resistance. This trade-off profile makes modal uniquely suited for specific product categories — which we'll cover next.

2. Why Knitwear Brands Love Modal Yarn

Unmatched Softness and Drape

Modal has a natural, almost silk-like luster and an exceptionally smooth surface. When knitted, modal fabrics flow and drape beautifully — making them ideal for garments where hand-feel is the primary selling point. This is why modal dominates in loungewear, underwear, and premium basic T-shirts.

Superior Moisture Absorption

With 50% higher moisture regain than cotton, modal absorbs perspiration faster and releases it more readily into the air. This keeps the wearer drier and more comfortable in warm conditions. For activewear and next-to-skin applications, this is a significant functional advantage.

Color Brilliance and Retention

Modal fibers have a round, smooth cross-section that reflects light evenly, producing brighter, more vibrant dye uptake than cotton. Colors appear richer, and the fiber holds dye well through repeated wash cycles — an important consideration for brands where color consistency is a brand signature.

Eco Credentials That Matter

Beechwood is a renewable resource that grows without artificial irrigation. The modal production process recovers and reuses processing chemicals at rates exceeding 95%. If you source Lenzing-certified modal, the fiber carries full traceability from forest to fiber — a compelling sustainability story for end consumers.

3. Modal vs Lyocell vs Cotton: Which Fiber for Which Product?

All three fibers have their place in a modern textile collection. The key is matching the fiber to the product's functional requirements and price point:

Product Category	Best Fiber	Why
Premium loungewear	Modal	Ultimate softness and drape; premium feel justifies cost
Underwear / intimates	Modal	Softness + moisture absorption; superior next-to-skin comfort
Basic T-shirts (mass market)	Cotton	Lower cost, better durability, familiar consumer expectation
Premium T-shirts	Modal-Cotton blend	Soft hand-feel with better cost structure than 100% modal
Athleisure / activewear	Lyocell or Cotton	Better wet strength; modal's lower wet tenacity is a liability
Towels / home textiles	Cotton	Higher absorbency and wet strength; modal is too delicate
Eco-conscious collections	Lyocell or Modal	Both have strong sustainability credentials; lyocell's closed-loop is the gold standard

4. Sourcing Modal Yarn: A Buyer's Checklist

When you're ready to source modal yarn — whether 100% modal or blended — here's what to verify with your supplier:

4.1 Fiber Origin and Certification

Ask your supplier: "Is this Lenzing Modal or generic modal?" Lenzing Modal carries Oeko-Tex Standard 100 certification, full forest-to-fiber traceability, and consistent quality. Generic modal can vary significantly in staple length, fineness, and contamination levels. The price difference is typically 8–15%, and for premium brands, the certification is worth it.

4.2 Yarn Count Options

Modal yarn is commonly produced in counts from Ne 20s to Ne 60s for knitting applications. For reference:

• Ne 30s – 40s: Most common for knitwear; good balance of softness and fabric weight
• Ne 50s – 60s: Ultra-fine yarn for premium lightweight knits; requires high-quality fiber input
• Ne 20s – 30s: Heavier gauge; used for sweaters and thicker knit structures

4.3 Spinning Technology

For modal yarn, ring spinning is the standard. Compact spinning can further reduce hairiness by 30–40%, producing a cleaner yarn surface — important for high-end knitwear where fabric appearance is critical. Ask your supplier whether they offer compact-spun modal yarn.

4.4 Quality Parameters to Inspect

Parameter	Acceptable Range	Premium Target
Yarn Evenness (CVm %)	≤ 14.0%	≤ 12.5%
Thin Places (-50%) / km	≤ 15	≤ 8
Thick Places (+50%) / km	≤ 80	≤ 50
Neps (+200%) / km	≤ 120	≤ 80
Hairiness (H)	≤ 5.5	≤ 4.5
Breaking Strength (cN/tex)	≥ 14.0	≥ 16.0
Twist CV%	≤ 5.0%	≤ 3.5%

4.5 MOQ and Lead Time

Typical MOQs for modal yarn from Chinese manufacturers:

• Stock yarn (standard counts like Ne 30s, Ne 40s): 500 kg – 1,000 kg per count
• Custom-spun (specific blend ratios, specialty counts): 2,000 kg – 5,000 kg minimum
• Lead time: 15–25 days for stock yarn; 30–45 days for custom orders

5. Modal Yarn Pricing: What to Expect in 2026

Modal yarn pricing varies based on fiber origin (Lenzing vs generic), count, and order volume. As of mid-2026, indicative FOB China pricing:

Yarn Type	Count (Ne)	Price Range (FOB USD/kg)
100% Modal (Generic)	30s – 40s	$3.80 – $4.50
100% Modal (Lenzing)	30s – 40s	$4.40 – $5.20
Modal/Cotton 50/50	30s – 40s	$3.20 – $3.80
Modal/Lyocell 50/50	30s – 40s	$3.60 – $4.20
