1, the category of functional fibers

    There are many types of functional fibers, and with the continuous development of fiber materials science, more and more high-performance functional fibers will be continuously developed. According to the source of fiber, functional fiber can be divided into natural functional fiber, regenerative functional fiber and synthetic functional fiber; according to the properties of the material, it can be divided into organic functional fiber and inorganic functional fiber; according to the application field of fiber, it can be divided into industrial functional fiber and fabric. Use functional fiber, functional fiber for home decoration, etc.; according to specific functional characteristics can be divided into flame retardant fiber, high strength fiber, high temperature resistant fiber, high hygroscopic fiber, moisture absorbing and wetting functional fiber, antibacterial bactericidal fiber, thermal insulation fiber, Flame-retardant functional fiber, morphological memory intelligent fiber, radiation-proof fiber, conductive, anti-static fiber, etc. Flame-retardant fiber can only cause flame-retardant fabrics, but the fibers used in some functional fabrics are not functional in nature. For example, flame-retardant fabrics are flame retardant fabrics with flame retardant properties after ordinary fabrics have been flame retarded. .

2, the performance of functional fibers

    Different functional fibers have different properties. Highly hygroscopic functional fibers and hygroscopic wettable fibers are two functional fibers of different properties. The macromolecule of the highly hygroscopic functional fiber contains a group capable of binding to water molecules such as a hydroxyl group or a carboxyl group, and has a strong hygroscopic ability and a weak ability to release moisture. The hygroscopic mechanism of the moisture-absorbing and moisture-conducting fiber is not exactly the same as that of the high-absorbency functional fiber. The hygroscopic mechanism is not only through a certain number of hydrophilic groups, but also through the hollow fiber with micropores on the surface. The effect will be wet.

    At the time of spinning, different functional synthetic fiber varieties can be obtained by adding functional ultrafine powders; far-infrared functional synthetic fibers can be obtained by adding blended ceramic ultrafine powders; and metals such as Cu and Ag are added and blended. The element and its compound or other antibacterial agent can obtain synthetic fiber with antibacterial function; the synthetic fiber with anti-ultraviolet function can be obtained by adding titanium dioxide, zinc oxide, etc.; and various discoloration ultrafine powders can be added and blended, and various kinds can be obtained. A synthetic fiber having a color-changing function; a synthetic fiber having a flame-retardant function can be obtained by adding a flame-retardant substance; and a synthetic fiber having a conductive function can be obtained by adding a conductive powder such as carbon black.

Good post-fire retardant fabrics have very good flame retardant properties, and also have good moisture absorption and drainage, which is very suitable for the manufacture of protective articles such as flame retardant tools.
