Spun-bonded non-woven fabric for diaper diversion layer and production technology of fabric

Abstract

The invention discloses a spun-bonded non-woven fabric for a diaper diversion layer and a production technology of the fabric. The non-woven fabric comprises an absorption core which is formed by coarse denier fiber, the direction of the coarse denier fiber is the longitudinal direction, the pattern of the coarse denier fiber is the strip pattern, the pattern of the absorption core is the patternof the character 'yi', and the pattern direction of the absorption core is consistent with the fiber direction. Compared with the prior art, the fabric has the advantages that a hot wind non-woven fabric can be replaced, the production speed of the spun-bonded non-woven fabric is higher than that of the hot wind short fiber, the cost is low, and the effect is good; the coarse denier product is good in diversion effect, diffusion is accelerated, the diffusion length is increased, and the amount of reverse osmosis is lowered; compared with ordinary hot wind non-woven fabrics and other products,the fluffiness is better, and the liquid absorbing speed is higher.

Description

technical field [0001] The invention relates to the technology in the field of spun-bonded nonwoven fabrics, in particular to a spunbonded non-woven fabric for a diaper flow guide layer and a production process thereof. Background technique [0002] Since diapers began to use polymer water-absorbent resin (SAP) in the 1980s, diapers have become thinner and thinner in design, and their performance has become better and better. Among them, SAP and non-woven components have more and more influence on product performance. bigger. SAP itself swells after absorbing water. If the content of SAP in the core layer exceeds a certain proportion, it is very easy to appear the phenomenon of adhesion between each other after absorbing liquid, which hinders the passage and absorption of liquid, that is, "gel blocking". [0003] By adding the diversion layer, the liquid can be effectively diffused and distributed in the diversion layer, and at the same time, the liquid can be slowly and ev...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art. The present invention provides a spunbonded nonwoven fabric for the diversion layer of diapers and its production process, which can effectively solve the problem of the slow production speed of the diversion layer of the existing diapers. The problem of poor drainage
