Abstract

The invention discloses an online continuous composite non-woven fabric production process. The produced non-woven fabric is composed of an upper staple fiber web, an intermediate non-woven fabric anda lower staple fiber web; the multi-layer composite structure reduces the phenomenon that the conventional spunlaced nonwoven fabrics are poor in strength and surfaces of the conventional spunlaced nonwoven fabrics are prone to sparse webs, and can effectively improve the strength and the uniformity of spunlaced nonwoven fabric products; online continuous composite once-forming can avoid the defect that the intermediate layer is formed and rolled firstly, and then transferring and back-rolling are performed, which costs lots of human and material resources; and the cost is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an online continuous composite nonwoven fabric production process. 【Background technique】 [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of breathability, softness, light weight, non-toxic and non-irritating, rich colors, and low prices. For example, polypropylene (PP) pellets are used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, hot rolling, and coiling. [0003] The strength of conventional spunlace nonwovens is poor and the surface of the fabric is prone to thinning. In order to solve the above problems, it is necessary to propose an online continuous composite nonwovens production process to improve the strength of spunlace nonw...
