Problems solved by technology

Such products generally contain slippery additives, and such additives will affect the bonding effect of hot melt adhesives and non-woven fabrics. If the amount of addition is not well controlled, once too much is added, it will lead to soft non-woven fabrics and non-woven fabrics. Other materials bond poorly or even fail to bond
[0003] Secondly, limited by the characteristics of the polypropylene material itself, after the surface of the polypropylene spunbonded non-woven fabric is hydrophilically finished, the product feels hard. If a slip agent is added for spinning and then the hydrophilic surface is finished, the product will have The problem that the hydrophilic effect may fail
In addition, some existing manufacturers adopt the production process of hydrophilic modification of polypropylene by blending and spinning hydrophilic masterbatches, which has high production costs and stability problems in the production process.

Abstract

The invention discloses a super-softness non-woven fabric and a super-softness hydrophilic non-woven fabric. The super-softness non-woven fabric is formed in the mode that a soft layer and a bonding face layer are subjected to hot rolling and solidified, the net forming gram weight ratio of the soft layer is larger than or equal to 70%, and the net forming gram weight ratio of the bonding face layer is smaller than or equal to 30%; as the bonding performance of the bonding face is improved, the glue applying amount is greatly decreased, the light-thin feeling of a non-woven fabric product is improved, the quality of the non-woven fabric product is improved accordingly, and the effect that the production cost is reduced is also achieved.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric production formula, in particular to a supersoft nonwoven fabric and a supersoft hydrophilic nonwoven fabric. Background technique [0002] Most of the thin and soft spunbonded nonwoven fabrics currently used in sanitary products have basically the same friction coefficient on the upper and lower sides. Such products generally contain slippery additives, and such additives will affect the bonding effect of hot melt adhesives and non-woven fabrics. If the amount of addition is not well controlled, once too much is added, it will lead to soft non-woven fabrics and non-woven fabrics. Other materials bond poorly or even fail to bond. [0003] Secondly, limited by the characteristics of the polypropylene material itself, after the surface of the polypropylene spunbonded non-woven fabric is hydrophilically finished, the product feels hard. If a slip agent is added for spinning and then the hydr...
