Polypropylene staple fiber is a kind of non-absorbent or very low water absorption, and it cannot be dyed and colored like other synthetic fibers such as polyester and eyeglass. Because of its high static electricity, it is difficult to perform processing such as clearing and spinning, which greatly restricts Based on its application, the high-efficiency, durable, practical antistatic agent and dyeable components were analyzed and screened. Polypropylene staple fiber is because polypropylene is located at the negative end of the fiber frictional charging sequence, so when it rubs with a fiber, It generates a negative charge by itself. This kind of fiber without modification treatment is prone to static electricity accumulation during use, and can cause many troubles in the processing process. Severe static electricity problems will directly affect the cleaning, carding and other processes, and it can't even be used for processing!
