Spunlaid, pulp airlaid and spunlace-bonded non-woven fabric production process

Abstract

The invention discloses a spunlaid, pulp airlaid and spunlace-bonded non-woven fabric, which comprises a first web, a second web and a pulp fiber layer, wherein the pulp fiber layer is arranged between the first web and the second web. The invention additionally discloses a spunlaid, pulp airlaid and spunlace-bonded non-woven fabric production process, which comprises the steps of melting, spinning, spunlacing, drying, thermal calendering and the like. By using polypropylene fibers and pulp paper as raw materials and combining a spunbonding method with a spunlacing method, the production cost is reduced; and through spunlacing, spunbonded filaments are enabled to be entangled in a staggered way and pulp fibers are scattered and covered in the spunbonded filaments which are entangled in the staggered way. The product not only has the characteristics of high strength and wear resistance of a polypropylene fiber spunbonded fabric, but also overcomes the defects that the water absorbability of the polypropylene fiber spunbonded fabric is poor, the polypropylene fiber spunbonded fabric is not apt to be dyed and the softness is poor.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to the technical field of the production process of nonwoven fabrics. Background technique [0002] Non-woven fabric is a kind of fabric that does not need spinning and weaving. It only uses short textile fibers or filaments to be oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Nonwoven fabric is a new type of fiber product with soft, breathable and planar structure formed directly by polymer chips, short fibers or filaments through various web forming methods and consolidation technologies. Its production process is short and the production speed is fast. , high output, low cost, wide application, and many sources of raw materials. [0003] The production process of spunbond and spunlace nonwovens has developed rapidly. They are two commonly used methods in the manufacture of nonwovens. The pro...

AI Technical Summary

Problems solved by technology

[0005] Although the above two methods can produce nonwoven fabrics, there are certain defects. The nonwoven fabric produced by the spunbond method has a hard hand and poor water absorption; while the nonwoven fabric produced by the spunlace method has poor strength. , high cost, with the continuous development of the market, people's demand and quality requirements for non-woven fabrics are getting higher and higher, the non-woven fabrics produced by the above two methods can no longer meet people's needs
