1. Luster: The biggest feature of profprofed fiber is its unique optical effect. The reflection intensity of the fiber surface of the circular section is no different from the direction of the incident light, but the reflection intensity of the fiber surface of the special-shaped fiber varies with the direction of the incident light. The optical characteristics of profile-shaped fiber enhance the luster of the fiber, so that human eyes in different directions, different positions to receive different optical information and produce good sensory feelings.

2. Wrinkle resistance and drawing property: the elastic modulus of special-shaped fiber is higher than that of circular section, so the deformation resistance is strong, and the wrinkle resistance effect is good. Just like the same length, weight of I - beam is better than round steel bending.

3. Fluffiness and air permeability: In general, the coverage and fluffiness of special-shaped fibers are better than those of ordinary synthetic fibers, and the fabric feels thicker, fluffiness, fullness and light weight. The more complex the section of profiled fiber, or the higher the profiled fiber degree, the better the fluffiness and air permeability of fiber and fabric.

4. Pilling resistance and grinding resistance: After fiber special-shaped, due to the increase of fiber surface area, the binding force between fibers in the filament increases, and pilling and pilling phenomenon is greatly reduced.

5. Dyeing and antifouling: special-shaped fiber due to the large surface area, the coloring speed is accelerated, and the dyeing rate is significantly increased.
