Cross Shaped Profile Polyester Staple 1.5D*38MM
Our 1.5D*38MM cross quadrilobal profile polyester staple fiber is a professional functional moisture-wicking textile raw material specially developed for the high-comfort quick-dry apparel industry. Breaking the performance limits of traditional circular polyester fiber, the exclusive four-groove cross melt-spinning structure integrates sweat transport, anti-pilling, soft touch, and breathable bulk into one fiber, making it the core preferred raw material for global sportswear and premium knitwear manufacturers.
Key Specifications
Cross shaped fiber with unique four-lobe profile
1.5D*38MM standard dimensions
Customizable specifications available
Technical Features
Manufactured using 100% virgin PET chip one-step melt spinning, each single fiber forms a stable four-lobe cross-section with continuous longitudinal capillary grooves. Unlike surface-coated hydrophilic fibers whose moisture-wicking function fades after washing, our capillary structure is an inherent fiber geometry, providing permanent quick-dry performance that never fails after repeated laundry and long-term use.
Features four continuous deep grooves forming natural micro-capillary channels between interlaced fibers. Rapidly absorbs sweat from skin surface and transports moisture to fabric outer layer for fast evaporation, with 40%-70% higher moisture management capacity than ordinary circular fiber.
38mm Standard Cotton-Type Length, Excellent Spinnability & Low Production Loss
Precision fixed 38mm cut with neat smooth incision and uniform fiber length. Matches all mainstream spinning equipment perfectly with less flying waste and low yarn breakage rate.
Superior Bulk & Air Permeability, Lightweight Warm Comfort
Massive micro air gaps formed by cross-lobe interweaving lock air inside fabric, providing lightweight fluffy bulk and outstanding air circulation for all-season comfort.
High Dye Uptake & Stable Color Fastness
Special cross-section structure expands fiber specific surface area, boosting dye absorption capacity. Achieves saturated, uniform shade with excellent color fastness.
Low Shrinkage & Wrinkle Resistant, Easy Care
Ultra-low boiling water shrinkage rate ≤2.0%. Fabrics maintain flat neat shape after washing with minimal ironing requirements.
Application Scenarios
Sport & Active Wear Fabric: Running jerseys, fitness leggings, basketball sportswear, yoga outfits, marathon quick-dry training clothes
Blended Functional Yarn: Blend with cotton, viscose or modal to balance softness, quick-dry performance and production cost
Frequently Asked Questions
Why is cross profile fiber more quick-dry than regular round polyester?
Four longitudinal capillary grooves form micro sweat transport channels between fibers. Capillary effect accelerates sweat absorption and evaporation, with wicking efficiency 40%-70% higher than circular fiber.
Will moisture wicking performance disappear after repeated washing?
The moisture transport function comes from inherent fiber cross geometric structure, not surface hydrophilic coating. Provides permanent quick-dry without attenuation after dozens of washes.
What is the anti-pilling level of finished fabric?
Fabric made of this cross staple reaches Grade 4-5 pilling resistance, hardly generates fuzz and balls under long-time friction.
Is 38mm length compatible with common spinning machines?
Standard cotton-type 38mm cut length fits all ring spinning, airflow spinning and spunlace nonwoven equipment, ensuring smooth high-speed processing with low yarn breakage.
Can it blend with cotton, viscose and other natural fibers?
Excellent blending compatibility with arbitrary mixing ratio adjustable to modify fabric softness, thickness and functional indicators.
Does cross fiber have harsh bright luster like ordinary polyester?
