1.5D*38MM Moisture Wicking Quick Dry Polyester Staple Fiber, for Sportswear Underwear & Jersey Fabric

Our 1.5D*38MM moisture wicking quick dry polyester staple fiber is a mature functional textile raw material developed with permanent hydrophilic graft modification technology, specially produced for high-comfort sweat-management apparel and daily breathable textiles.

• Athletic & Fitness Apparel: Quick-dry jerseys, running t-shirts, training suits, basketball uniforms, cycling base layers
• Daily Close-Fitting Wear: Breathable thermal underwear, casual tees, men and women sweat-wicking socks
• Outdoor Functional Textiles: Hiking clothes, camping wear, fishing garments, travel quick-dry suits
• Home Textiles: Moisture absorbent bed sheets, pillowcases, cooling blankets, breathable towel fabrics
• Nonwoven Industry: Sweat-absorbing disposable wipes, functional sanitary nonwoven, sweat pad filling materials
• Yarn Production: Pure moisture-wicking spun yarn, blended functional yarn for knitting and weaving factories

This fiber adopts internal graft hydrophilic modification instead of temporary surface coating treatment. The moisture-absorbing molecular chain is firmly combined with polyester substrate, so sweat wicking capability will not fade after dozens of repeated laundry cycles.

Special irregular cross-section structure forms countless tiny capillary channels inside each filament. When skin sweats, moisture is quickly pulled away from body surface, transported to fabric outer layer and evaporated rapidly.

1.5D is a universal optimized denier for functional apparel. It delivers soft, smooth and non-irritating hand touch close to cotton, while retaining strong tensile strength and structural stability.

Precisely fixed 38mm cutting length with neat incision and stable length uniformity ensures excellent spinnability with low yarn breakage rate on all mainstream cotton and worsted spinning machines.

Finished by high-temperature setting craft, the fiber owns low boiling water shrinkage rate. Fabrics maintain original shape and size after washing, reducing post-production shaping loss.

Dry fabric surface avoids sweat residue buildup that breeds bacteria and unpleasant body odor. The fiber surface has mild anti-static property, preventing garment clinging tightly to skin.

A1: It adopts internal graft hydrophilic modification, the function is built into fiber structure instead of surface coating. Performance remains stable after repeated washing cycles.

A2: 1.5D balances soft skin-friendly touch and solid fiber strength, it is the most versatile spec for sportswear, underwear and socks, widely accepted by spinning factories globally.

A3: Yes, it mixes evenly with cotton, viscose and regular polyester to adjust fabric breathability, softness and cost freely.

A4: The fiber is heat-set with low boiling water shrinkage, finished fabrics maintain good dimensional stability after washing.

A5: Raw white fiber has excellent dye absorption capacity, supports full color spectrum dyeing with reliable color fastness.

A6: Small test samples are provided free of charge for lab performance and spinning trials.

A7: Mainly for sportswear, fitness wear, quick-dry underwear, sweat socks, breathable bedding and functional sweat-absorbing nonwovens.

A8: Custom denier, length and hydrophilic strength can be arranged for large volume bulk orders.
