What are special-shaped fibers?
12Synthetic fibers with non-circular cross-sections spun with special-shaped spinnerets. Synthetic fibers have various unique properties. However, some wearing properties after being made into fabrics are often not as good as natural fibers. In order to make synthetic fibers have the advantages of wool or silk, the structural characteristics of natural fibers are often imitated. Without damaging the basic properties of the fibers, the spinning fluid is extruded through specific spinneret holes to form synthetic fibers with corresponding cross-sections. Fiber, which is a physical modification method. The cross-section of the fiber produced by spinning viscose or acrylic is not round, but zigzag or dumbbell-shaped, but it is not a special-shaped fiber.
The cross-sections of special-shaped fibers include triangular, pentagonal, trilobal, multi-lobed, dumbbell-shaped, oval, L-shaped, lotus root-shaped, round hollow and special-shaped hollow. Different types of profiled fibers have different properties. Triangular fibers are glittery and can be used to make beautiful glittery yarns and outerwear. Pentagonal fiber has a distinct wool feel and good pilling resistance, and can be used to make high-end silver gun coats. The pentacle-shaped fiber is very similar to silk. The fabric is light, soft and smooth without a waxy feel. It can be made into clothing that has the feel of real silk and the refreshing characteristics of chemical fibers. L-shaped fiber has good hygroscopicity; hollow fiber has light specific gravity, warmth retention and good hand feel, and can be made into cotton or blankets.
Special-shaped fibers are generally manufactured using special-shaped spinneret holes. Selecting spinneret holes of different shapes can produce special-shaped fibers with different cross-sections. Technologies such as melt mutual adhesion, separation of composite filaments, post-processing deformation, center air blowing, composite special-shaped filaments, etc., or fiber surface deformation and other methods can also be used to manufacture special-shaped fibers.
Special-shaped fibers can be spun into monofilaments, multifilaments, short fibers, fiber bundles, elastic yarns, etc. Fabrics made from special-shaped fibers have a shiny and soft, smooth, bulky feel, close to wool or silk. Special-shaped fibers are suitable for making various novel fabrics, artificial fur, synthetic leather base fabrics, artificial suede, etc., and are also used in medical treatment, three-waste treatment, and cigarette filters.
