High Hollow Deformed  Polyester Fiber

Reasons for recommendation

The novel pentagonal hollow cross-sectional design alters the load.

bearing state of the fiber, the pathway for light reflection, and the

direction of water on the fiber’s surface, giving the fabric its light.

warm, plump, soft, dry, and other characteristics.The fiber has many

applications in the fields of outdoor sports, skin-fitting underwear, and

thermal underwear.

Preparative technique

The polyester pellets are combined with the special pentagonal hollow cross-sectional design, and prepared by melt spinning process.

Performance indexes of high hollow deformed polyester fiber

The downstream application guidance

Weaving: In order to avoid affecting the roundness of the mono-filament, tension should be properly managed during the fabric manufacturing process.

Dyeing: Good color absorption, with a slightly lower dying temperature than regular fibers.

Storing: Fabrics should not be stacked too high to prevent heavy pressure affects the degree of hollowness.

Application of fibers

Clothing textiles:Leisure wear/Sportswear/Lingerie

Home textiles:Blanket

Q: What advantages does the special pentagonal hollow deformed cross

section bring to the fiber?

A: Pentagonal hollow profiled fiber can increase the coefficient of friction of the fabric, and improve the waxy feel of the fabric. In terms of luster, the pentagonal hollow profiled design has a dispersive reflection and extinction effect on the light; the fiber’s large specific surface area allows it to color quickly and enhances the fabric’s apparent covering, making it difficult to see through.
