91 Polyester 9 Spandex For Lining,Dress,Shirt

Have you ever faced the problem of sportswear losing its shape after just 20 washes? That's precisely why brands like H&M made the switch to our 91/9 poly - spandex woven fabric last year. Their yoga pants used to have seam slippage issues until we fine - tuned our 2×1 twill construction. We tightened the weft density to 78 picks/inch while still maintaining a 36% stretch recovery. Here's how this fabric addresses real - world production challenges:

Technical Backbone:
We begin with 75D semi - dull polyester yarn sourced from the SINSUN Group, which is interwoven with 40D spandex cores. Unlike cheaper alternatives that use single - cover spandex, our dual - core yarn wrapping technique prevents filament breakage during high - tension weaving on Tsudakoma air - jet looms. Reactive dyeing at 130°C guarantees color fastness ratings of 4 - 5 even after more than 50 industrial washes, as verified by Martindale abrasion tests exceeding 18,000 cycles. The outcome is a fabric that retains 92% of its elasticity at 20% extension even after rigorous laundering.

Why Global Brands Trust This Blend:

• Win/Win Durability: The Spanish activewear brand Marqopa managed to reduce returns by 17% after switching to our 230GSM variant. The key lies in the pre - shrunk spandex that is stabilized through post - weft heat - setting at 195°C.
• Color Consistency Guaranteed: Our ISO - certified lab employs Datacolor 800 spectrophotometers to ensure a ΔE≤0.8 batch - to - batch accuracy. This is crucial for Zara's 12 - color capsule collections.
• Eco - Efficient Production: We offer GRS - certified recycled polyester options, which can slash CO₂ emissions by 63% compared to sourcing virgin polymers.
