Today we will come together to understand the categories of Differential PP FDY.
1. Divided from morphological structure
Divided from the morphological structure, the Differential PP FDY mainly has shaped fibers, hollow fibers, composite fibers and fine fibers.
The shaped fiber is a chemical fiber having a special cross-sectional shape spun through a certain geometrical (non-circular) spinning hole, and depending on the orifice used, a triangular, polygonal, trilobal, multilobal shape can be obtained. , cross, flat, Y, H, dumbbell, etc. The hollow fiber is a chemical fiber which penetrates the fiber axial direction and has a tubular cavity. It can be obtained by changing the shape of the spinning hole by the shaped fiber. The biggest feature is that the density is small and the warmth is strong, and it is suitable for down products such as high-grade cotton. , imitation down jacket, sleeping bag, etc. The composite fiber is a chemical fiber which is spun by two or more polymers or the same polymer having different properties by a composite spinning method, and the fiber is made of two polymers, that is, a double group. Fiber. In addition, there is a fine fiber, which is a fiber having a small single wire density, which is also called a fine fiber.
The methods generally used for spinning fine fibers include a composite spinning stripping method, a dissolution method, a conventional melting method, an ultra-stretching method, a flashing method, and a melt blowing method. In particular, polyester fine fiber has a dominant position in textile fibers because of its good taking performance. It has imitated high-simulation fiber in place of natural fiber, which makes the silk fabric light, soft, smooth and smooth. The ultra-thin polyester fabric is treated with alkali reduction, and then subjected to special soft and hydrophilic finishing to obtain the appearance and feel of the real silk.
2. Divided from physical and chemical properties
From the physicochemical properties, the Differential PP FDY has antistatic fiber, high shrinkage fiber and flame retardant fiber.
Antistatic fibers refer to chemical fibers that do not readily accumulate static charges. Antistatic fibers are mainly used in the production of dust-free sterile clothing, explosion-proof overalls, carpets, masks and other textiles. High shrinkage fibers are available in different styles and properties depending on the degree of heat shrinkage. Flame-retardant fiber can also be called flame-resistant, flame-retardant or flame-retardant fiber. It is a chemical fiber with flame retardant component that is only smoldering in flame and does not produce flame. It is self-extinguishing after leaving the fire source. It is mainly used for spinning. Children's and seniors' clothing, bedding, decorative fabrics, fireproof overalls, and ropes, tents, industrial fabrics, etc. with flame retardant requirements.
Fiber is given a special function and becomes a functional fiber. Functional fibers can be divided into four categories according to their functional properties: physical functional fibers, chemical functional fibers, material-separating functional fibers, and biocompatible functional fibers.
Since its establishment, Guangdong Mengtai High-tech Fiber Co., Ltd. has developed steadily. At present, it has an annual output of more than 30,000 tons of polypropylene filaments of various specifications. It has become a professional manufacturer of polypropylene filaments with large scale and high output in China. Silk, ultra-fine denier polypropylene filament, polypropylene network yarn, polypropylene hollow filament, polypropylene DTY filament, Differential PP FDY are sold in many countries and regions. The products cover luggage, clothing, shoes and hats, furniture and other industries, and have entered thousands of households. .
