What are the main raw materials of non-woven fabrics?

It is a man-made cellulose fiber, spun by the solution method. Since the solidification rate of the fiber core layer is not consistent with the solidification rate of the outer layer, a skin-core structure is formed (clearly seen from the cross-section). Viscose is the most hygroscopic among ordinary chemical fibers, with good dyeability, good wearing comfort, poor viscose elasticity, poor wet strength and wear resistance, so viscose cannot be washed with water and has poor dimensional stability. Heavy weight, alkali and acid resistance.

Viscose fiber is widely used in almost all types of textiles, such as filament lining, silk, flags, webbing, tire cord, etc.; short fiber is used for imitating cotton, wool, blending, weaving, etc.
