Problems solved by technology

The two methods have their own disadvantages. 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 eliminated the traditional staple fiber carding process, the fiber web Reinforced materials are still prepared offline. The offline method has a long production process, high equipment investment, large plant area, complex production operations, and low production efficiency and high production costs due to offline operations.

Abstract

An online creel reinforcement production method for spunbond needle-punched non-woven fabrics is characterized by including steps: firstly, polymer spunbond non-woven fabric preparation; secondly, reinforcement material production; thirdly, spunbond needle-punched non-woven fabric online creel reinforcement preparation. The method has advantages that online implementation of spunbond net formationand reinforcement production can be realized, a production process is simplified, equipment investment is saved, labor intensity is relieved, energy consumption is reduced, product usability is improved, dimensional stability is improved, anti-tear strength is enhanced, the shrinkage rate is decreased, and high asphalt impregnation speed and production efficiency improvement are realized.

Description

technical field [0001] The invention belongs to the industry of spun-bonded nonwoven fabrics in the field of industrial textiles, in particular to a method for producing nonwoven fabrics with reinforcement on an online creel. Background technique [0002] At present, most of the methods for manufacturing composite reinforced nonwoven fabrics use the production method of adding reinforcement materials off-line after carding short fibers into a web, and a few adopt the preparation method of adding warp threads off-line after spunbond filaments are formed into a web. The two methods have their own disadvantages. 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 eliminated the traditional staple fiber carding process, the fiber web Reinforced materials are still prepared offline. The offline method has a long production process, hi...
