Staple fiber
Short fibers, also known as staple fibers, are cut or broken into fibers corresponding to the length of various natural fibers. Short fiber boundaries, the length is generally 35 ~ 150mm. According to the specifications of natural fibers, it can be divided into short fibers such as cotton, wool, carpet and medium-length.
Natural fibers such as whiskers and asbestos can also be used.
They can be purely spun, or blended with different proportions of natural or other fibers to form slivers, fabrics and felts.
For example, a general-purpose pitch carbon fiber is cut into a 150 mm long, 15 μm diameter, 800 MPa, carbon fiber having a modulus of 41 GPa, and mixed with a phenolic carbon fiber (length 70 mm, strength 200 MPa, diameter 14 μm) at a ratio of 8:2. Stable and uniform yarn. Woven into various shapes of fabric or chopped fiber for reinforcement of composite materials such as cement and aluminum alloy.
Filament
Filament, also known as continuous filament, is a type of chemical fiber. Filaments are filaments of very long continuous length. In the process of chemical fiber production, the spinning fluid is continuously extruded from the spinning hole, cooled by air or solidified into a filament in a coagulation bath, and becomes a continuous yarn, which is then subjected to stretching, twisting, or deformation. Process for further processing applications. The filaments thus obtained having a length of several kilometers or tens of thousands of meters can be divided into two types, a monofilament and a multifilament. Chemical fiber filaments are commonly used in a variety of clothing, decorative and other industrial sectors.
