Composite nno-woven cloth and composite non-woven cloth product

Abstract

A non-woven composite fabric is composed of at least two of carded mesh layer, spunbonded mesh layer, melt-blown mesh layer and air-laid mesh layer. At least one of said mesh layers has the bonded fiber which contains maleic acid or maleic anhydride grafted polyolefin. It can be used to prepare diaper and sanitary napkin, which has high stripping strength, mechanical strength and transverse strength.

Description

technical field

[0001] The present invention relates to a kind of composite non-woven fabric and composite non-woven fabric product, especially relate to the adhesive fiber that uses the olefin polymer that contains maleic acid (maleic acid) or maleic anhydride (maleicanbydride) to graft and make with High peel strength composite nonwovens and composite nonwoven products. Background technique

[0002] Non-woven fabrics have been widely used in household products and medical products, such as sanitary pads, disposable diapers, sanitary napkins, surgical gowns, etc. Generally speaking, the composite non-woven fabric is usually composed of different multi-layer web layers (web), and the manufacturing method is generally to consolidate the multi-layer web layers according to the needs. For example, in U.S. Patent No. 4,196,245, it is mainly to use a melt blown (meltblown) net layer to be combined with other net layers, and other net layers can be spunbonded (spunbonded) net lay...
