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.

Our 30s Black Recycled Polyester Cotton Yarn is a versatile, high-performance staple for textile manufacturers, engineered to balance uncompromising durability, premium softness, and verifiable sustainability. Blending 70% GRS-certified recycled polyester (sourced from post-consumer PET bottles) and 30% GRS-certified recycled cotton (reclaimed from pre-consumer cotton garment waste), this dope-dyed jet black yarn merges the structural resilience of polyester with the breathable, natural hand feel of cotton. Designed for high-volume industrial production, it meets strict global safety and sustainability standards, making it the ideal choice for brands prioritizing eco-friendly manufacturing without sacrificing product quality.
Our GRS certified recycled polycotton yarn cuts carbon emissions by 45% and water usage by 60% compared to virgin fiber blends, with each ton recycling 28,000 PET bottles and 1.2 tons of cotton waste. It holds OEKO-TEX® Standard 100 certification, fully aligning with EU and US ESG requirements to reduce your brand’s compliance audit costs.
This ring spun recycled yarn for high-volume weaving delivers 4.2–5.8 cN/dtex tensile strength and Level 4–5 pilling resistance (ASTM D3512). Its low-fuzz texture minimizes loom and knitting machine jams, while ±3% yarn count consistency across batches cuts defect rates and material waste in full-run production.
Our dope dyed black recycled yarn locks pigments into the fiber core during extrusion, resisting fading even after 100+ industrial washes (ISO 105-C06). It eliminates energy-intensive post-production dyeing, reduces your carbon footprint, and ensures zero color bleeding in 60°C hot washes for consistent end-product quality.

Our production starts with sorted, cleaned post-consumer PET bottles and pre-consumer cotton waste, melted into polymer chips and infused with black pigments via dope dyeing before spinning. We use advanced ring-spun equipment to create uniform, low-fuzz strands, with layer-by-layer quality control: every batch undergoes yarn count, tensile strength, color fastness, and pilling testing against ISO and ASTM standards. We issue full test reports for each bulk order to guarantee zero batch-to-batch variation.
This recycled polycotton yarn for denim & shirting is perfect for black jeans, tailored outerwear, and little black dresses, delivering long-lasting color and abrasion resistance for daily-wear garments.
Our black recycled yarn for blackout curtains & upholstery is ideal for bedroom blackout curtains, modern furniture upholstery, and wrinkle-resistant bed linens, with consistent color and structural stability for large-format production.
This high-strength recycled yarn for tactical gear suits military uniforms, tactical equipment, and automotive interiors, where color consistency, durability, and low maintenance are non-negotiable.
For industrial use, this yarn is compatible with most rapier looms, air-jet looms, and circular knitting machines, with a recommended knitting speed of 800–1200 rpm and sewing thread tension of 12–15 cN. It withstands ironing up to 150°C without discoloration or shrinkage. Store in a dry, ventilated space with 45–65% relative humidity, 10–30°C temperature, away from direct sunlight and rain, with stacking height not exceeding 8 layers to avoid yarn deformation.
Standard bulk orders for our stock jet black shade have a 4–6 week lead time; custom poly-cotton blends or color specifications require 8–10 weeks for production and quality validation.
Yes. Its high tensile strength, low-fuzz texture, and consistent thickness make it suitable for heavy-duty stitching in upholstery, garment construction, and technical textile manufacturing.
No. Our dope dyeing process locks pigments into the fiber core, ensuring zero bleeding in cold and hot industrial washes (tested up to 60°C), with no fading after 100+ wash cycles.
For textile manufacturers and bulk purchasers seeking high-quality, sustainable 30s black recycled polyester cotton yarn, we offer fully customizable solutions including custom blend ratios, color matching, packaging, and branding.
