Problems solved by technology

Both methods have their own disadvantages. The former has backward process route, complicated production process, poor product quality, high one-time investment in equipment, waste of manpower and power resources, etc.; although the latter has made great technological progress compared with the former, it will spin spinning The web-forming process route has been upgraded to a one-step method, and the traditional staple fiber carding and web-forming process has been eliminated. However, the production method of offline reinforcement is still used for fiber web plus warp. This method has a long production process, high equipment investment, and a large area Large, complex production operations, and the disadvantages of low production efficiency and high production costs due to offline operations

Abstract

The invention relates to an online pan head reinforcement production method for the spunbonded needle-punched nonwoven fabric. The method is characterized by comprising steps of S1,preparing the polymer spunbonded nonwoven fabric; S2, preparing the reinforcing material; and S3, preparing the spunbonded needle-punched nonwoven fabric with online pan head reinforcement. The method is advantaged in that the method can make the spunbonded web forming and reinforcement production process perform online, simplify the production process, save equipment investment, reduce labor intensity, reduce energy consumption, improve product performance, improve dimensional stability, increase tear strength, reduce the shrinkage rate, speed up the dipping speed and greatly improve production efficiency.

Description

Technical field [0001] The invention belongs to the industrial textile industry, in particular to a production method for on-line pan-head reinforcement of spunbonded needle punched nonwoven fabrics. Background technique [0002] At present, there are nonwoven fabric reinforcement production methods in China, most of which are nonwoven fabric production methods of carding staple fiber and adding warp threads, and a few of them adopt spunbond filaments to form a web and offline adding warp threads. Both methods have their own drawbacks. The former has backward process routes, complex production processes, poor product quality, high one-time investment in equipment, waste of manpower and power resources, etc.; although the latter has made great technological progress compared with the former, it will spin spinning The netting process route is upgraded to a one-step method, eliminating the traditional short fiber carding netting process, but the fiber web plus warp yarn still adopts...
