Composite fibers are one type of multicomponent fibers, a term for the rayon variety. Two or more unmixed polymer fibers exist on the same fiber section, and the fibers are called composite fibers. Bicomponent fibers having both polymer properties can be obtained using conjugate fiber manufacturing techniques. There are side-by-side, sheath-core, sea-island and other composite fibers, and the cross section of the fiber has a round shape and a special shape. The fiber has three-dimensional crimp, high fluffiness and coverage, and good conductivity, antistatic property and flame retardance. The composite fiber needs to be spun by a composite spinning machine with a special structure. The fabric is mainly used for wool, blankets, wool fabrics, thermal wadding fillers, silk fabrics, non-woven fabrics, medical and sanitary products, special work clothes and the like.
