This 1.5Dx38mm virgin polyester staple fiber is a universal cotton-type fiber, manufactured from 100% new virgin polyester chips with no recycled material blending. Fully compatible with conventional cotton spinning equipment, it supports pure spinning or blended spinning with cotton, viscose, modal and other fibers. It effectively solves common pain points of ordinary staple fibers, such as inconsistent dyeing, unstable spinning and poor finished-product durability, providing a cost-effective, highly reliable fiber solution for large-scale production.
Pain Point: Inconsistent fiber quality across batches causes frequent yarn breakage, dye streaks, high production waste and low finished product yield.
Solution: Our virgin PSF eliminates impurities and performance fluctuations caused by recycled materials at the source, with strict batch-to-batch consistency control.
Verifiable Evidence: With a breaking strength of ≥4.0cN/dtex, markedly higher than equivalent recycled fiber, it reduces end breakage during production, ensures uniform yarn evenness, and significantly improves production yield for downstream manufacturers.
Pain Point: Fabrics made from low-grade staple fiber are prone to wrinkling, shrinkage, pilling and poor color fastness, shortening product lifespan and damaging brand reputation.
Solution: The stable molecular structure of virgin polyester delivers excellent wrinkle resistance, dimensional stability, wash resistance and color fastness.
Verifiable Evidence: Fabrics produced with our fiber maintain their shape and smoothness after long-term use and repeated laundering, significantly extending the service life of apparel, home textile and industrial products.
Pain Point: Customized special fiber specifications require equipment modification, high procurement costs and unstable supply chains.
Solution: Our 1.5Dx38mm spinning-grade virgin polyester staple fiber adopts the global universal standard specification, with perfect compatibility with mainstream ring spinning and open-end spinning equipment.
Verifiable Evidence: It can be put into production directly without additional equipment modification, with lower procurement cost and more stable supply than customized specifications, while its smooth spinnability reduces energy consumption and labor costs.
