Black 30s Recycled Polyester Cotton Yarn Weaving

Product Overview

Our Black 30s Recycled Polyester Cotton Yarn is a versatile basic for textile manufacturers, offering a perfect balance of strength, softness, and sustainability. Blending 70% recycled polyester (from PET bottles) and 30% recycled cotton (from discarded cotton garments), it combines polyester’s durability with cotton’s natural feel. The deep, jet-black color is achieved through dope dyeing—where pigments are infused into the polyester melt before spinning—ensuring permanent colorfastness that resists fading even after repeated washes. This eliminates the need for energy-intensive post-production dyeing, reducing environmental impact while delivering a rich, uniform black hue. Ideal for fashion, upholstery, and technical textiles, it balances performance with eco-credentials for modern manufacturing needs.

Product Specifications

Material: 70% recycled polyester + 30% recycled cotton (both GRS-certified)

Yarn Count: 30s (medium-fine, 15–17 tex), suitable for lightweight to medium-weight fabrics

Color: Jet black (Pantone Black 6 C equivalent, with L-value = 15 for deep, uniform darkness)

Tensile Strength: 4.2–5.8 cN/dtex (high tear resistance for structured fabrics)

Moisture Absorption: 4–6% (quick-drying properties, ideal for active use)

Pilling Resistance: Level 4–5 (ASTM D3512), thanks to ring-spun construction

Certifications: OEKO-TEX® Standard 100, GRS

Product Features

Permanent Color: Dope-dyed black resists fading even after 100+ washes (ISO 105-C06), outperforming piece-dyed yarns that may bleed or dull over time.

Sustainable Design: Reduces carbon emissions by 45% and water usage by 60% compared to virgin fiber blends, with each ton of yarn recycling 28,000 PET bottles and 1.2 tons of cotton waste.

Smooth Surface: Ring-spun construction creates a uniform, low-fuzz texture that minimizes pilling and ensures crisp stitch definition in both woven and knitted fabrics.

Multi-Purpose Use: Seamlessly transitions between weaving (denim, shirting) and knitting (socks, sweaters), making it a versatile staple for textile manufacturers.

Applications

Fashion Industry: Black jeans, little black dresses, and tailored outerwear for a sleek, timeless look that retains color vibrancy through seasons.

Home Textiles: Blackout curtains for bedrooms, leatherette-style upholstery for modern furniture, and wrinkle-resistant bed linens.

Technical Textiles: Military uniforms, tactical gear, and automotive interiors requiring color consistency, durability, and low maintenance.

FAQ

Q: Can I use this yarn for sewing thread?

A: Yes. Its high tensile strength and smooth texture make it suitable for heavy-duty stitching in upholstery and garment construction.

Q: Does the black color bleed?

A: No. Dope dyeing ensures pigments are locked into the fiber structure, resulting in zero bleeding in both cold and hot washes (tested up to 60°C).

Q: What is the lead time for bulk orders?

A: 4–6 weeks for standard orders (using our stock black shade); 8–10 weeks for custom blends (e.g., adjusted poly-cotton ratios).

Q: Is it suitable for high-temperature ironing?

A: Yes. It withstands ironing temperatures up to 150°C without discoloration or shrinkage, making it easy to maintain garment crispness.
