Description
Technical Field
The invention belongs to the field of material science and engineering, relates to a processing method of non-woven fabric, and particularly relates to a processing method for preparing needle-punched non-woven fabric from waste polyethylene filament with ultrahigh molecular weight.
Background
Ultra-high molecular weight polyethylene, abbreviated as UHMWPE, is unbranched linear polyethylene having a molecular weight of more than 150 ten thousand. The ultra-high molecular weight polyethylene fiber has excellent mechanical properties, and has the characteristics of high strength, high modulus and low density. The ultra-high molecular weight polyethylene fiber product has good impact resistance, large specific energy absorption, excellent wear resistance and chemical corrosion resistance and light weight, so the ultra-high molecular weight polyethylene fiber product is widely applied to the fields of individual protection products, industrial textiles, sports equipment and the like.
The excellent mechanical properties of ultra-high molecular weight polyethylene fibers benefit from a highly oriented macromolecular structure. In the process of preparing the ultra-high molecular weight polyethylene fiber, macromolecules in the fiber are orderly oriented and highly crystallized by drafting the protofilament by a large factor, so that the mechanical properties of the ultra-high strength and the modulus of the fiber are obtained.
Because the molecular weight of the fiber is higher and the external force resistance is strong, only a hot stretching process can be adopted in production, and the drafting process of protofilaments needs to be carried out in a high-temperature environment. In this process, the broken filaments are often generated due to the mismatch of the drawing multiple and the temperature. The broken filaments have high strength generally, but cannot be used as the raw materials of woven fabrics or non-woven fabrics like filaments, and resource waste and environmental pollution are easily caused if the filaments are not utilized.
