Artificial ceramics are textile fibers made of materials containing natural fibers or protein fibers, such as wood, sugar cane, reed, soybean protein fibers, and other fiber raw materials that have lost their textile processing value. Man-made fibers mainly used for textiles are: viscose fiber, acetate fiber, cupro fiber. Regenerated fibers refer to fibers made from highly purified slurries made of natural polymers, such as regenerated cellulose Alumina Ceramic Rod fibers, regenerated protein fibers, regenerated starch fibers and regenerated synthetic fibers. The chemical composition of synthetic fiber is completely different from that of natural fiber. It is made from some substances that do not contain cellulose or protein, such as petroleum, coal, natural gas, limestone or agricultural and sideline products, first to synthesize units, and then to chemical synthesis and mechanical processing. into fibers. Such as polyester fiber (polyester), polyamide fiber (nylon or nylon), polyvinyl alcohol fiber (vinylon), polyacrylonitrile fiber (acrylic fiber), polypropylene fiber (polypropylene), polyvinyl chloride fiber (chlorine), etc.
Inorganic fibers are made from natural inorganic or carbon-containing polymer fibers by artificial spinning or direct carbonization. Including fiberglass, metal fiber and carbon fiber.
According to the length and fineness, there are cotton type (38 ~ 51mm), wool type (64 ~ 114mm), silk type (filament), medium and long type (51 ~ 76mm), ultra-fine type (<0.9dtex).
According to the cross-sectional shape, there are ordinary circular, Alumina Ceramic Rod hollow and special-shaped fibers, as well as annular or sheath-core fibers.
According to the curl, there are high curl, low curl, different curl, and no curl.
Differentiated fibers; high performance fibers; functional or smart fibers.
According to the processing method, there are different primary and modified fibers for natural fibers.
There are high-speed spinning, drawn yarn (DTY), pre or fully oriented yarn (POY or FDY), textured yarn (DTY), etc. According to the state of resource reserve, it can be divided into large kinds of fibers and special fibers. Fiber filling can effectively improve the strength and stiffness of plastics. Fiber-reinforced plastics are rigid structural materials. Fiber-reinforced plastics mainly have two components. The matrix is a thermoset or thermoplastic, filled with fibrous material. Typically the matrix has a lower strength, while Alumina Ceramic Rod the fibrous filler is more rigid but brittle. In the reinforced plastic obtained by compounding the two, the fiber bears a large load stress, and the matrix resin supports the fiber and transmits the external load through the shear stress on the interface with the fiber. Thermosetting plastic fiber reinforced plastics are abbreviated as FRP (fiber reinforced plastics), thermoplastic fiber reinforced plastics are abbreviated as FRTP (fiber reinforced thermoplastics). Fibers are prefixed with B; reinforced with aramid fibers (Kevlar) are prefixed with K.
