Abstract

The invention discloses an ultrahigh molecular weight polyethylene filament nonwoven fabric based on film-splitting method, comprising filament fiber mesh made by laying ultrahigh molecular weight polyethylene fiber filaments 0.5-20 dtex in average fineness, the filament fiber mesh is compressed by means of repeated needle-punching reinforcing and drawing to form the ultrahigh molecular weight polyethylene filament nonwoven fabric based on film-splitting method. The production process comprises: (1) preparing materials; (2) splitting; (3) lapping; (4) needle-punching; (5) rolling. The ultrahigh molecular weight polyethylene filament nonwoven fabric based on film-splitting method and the production process thereof have the advantages that the fabric is produced by one-time forming, the defects of the prior art such as poor firmness of nonwoven fabric and complexity of the preparation process can be overcome, overall strength of the filament nonwoven fabric is enhanced, and the nonwoven fabric has good water permeability and air permeability and is widely applicable.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an ultra-high molecular weight polyethylene filament non-woven fabric based on a film splitting method and a preparation process thereof. Background technique [0002] The preparation materials of the uniaxially stretched film are ultra-high molecular weight polyethylene, PTFE, polypropylene, PPS (polyphenylene sulfide), P84 (polyimide), among them, ultra-high molecular weight polyethylene fiber, also known as high-strength and high-modulus polyethylene Fiber is currently the fiber with the highest specific strength and specific modulus in the world. It is a fiber spun from polyethylene with a molecular weight of 1 million to 5 million. Ultra-high molecular weight polyethylene fiber has low elongation at break, large work of break, and strong energy absorption capacity, so it has outstanding impact resistance and cut resistance. At the same time, it has anti-ultraviolet...
