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]
The present invention relates to the technical field of non-weaving cloth, particularly the technical field of the production technology of non-weaving cloth.
[background technology]
Non-weaving cloth is a kind of fabric that does not need to spin cotton and weave cloth and form, and only uses textile staple or long filament are carried out orientation or random alignment, forms fibre net structure, then adopts the method reinforcing such as mechanical, hot sticky or chemical to form.Non-weaving cloth is the tencel goods with softness, ventilative and planar structure that directly utilize high polymer section, staple fibre or long filament to form by various fibre web manufacturing process and concretion technology, its technological process of production is short, speed of production is fast, and output is high, cost is low, purposes is wide, raw material sources are many.
Spun-bond process and the development of water acupuncture manipulation nonwoven manufacturing technique are rapidly, two kinds of processes commonly used during non-weaving cloth is made, the Spunbonded Nonwovens production technology claims again the polymer spinning to become the net method, to utilize the synthetic fiber spinning principle, make the laid one-tenth net of continuous filament fibers in polymer spinning process, fibre web tangles into non-weaving cloth through hot rolling or pinprick reinforcement.
Water acupuncture manipulation non-weaving cloth claims again the jet net-spraying method non-weaving cloth, short fiber is made fibre web after the opening or cleaning combing, then utilize water under high pressure to produce numerous superfine liquid drugs injection directive fibre web, make fiber under the effect that is subject to the different directions jet and mutually tangle, thereby fiber web is reinforced, tangled into non-weaving cloth.
Although above-mentioned two kinds of methods can be produced non-weaving cloth, all have certain defective, the non-weaving cloth feel that spun-bond process is produced is harder, and water imbibition is relatively poor; And the non-weaving cloth that the water acupuncture manipulation is produced is powerful poor, cost is high, and along with the development in market, people are more and more higher to demand and the quality requirement of non-weaving cloth, and the non-weaving cloth that above-mentioned two kinds of methods are produced can not satisfy people's needs.
