Abstract

The invention discloses a non-woven fabric with an excellent moisture-proof property. The non-woven fabric is prepared from, by weight, 40-55 parts of polyethylene, 16-23 parts of latex, 5-11 parts ofmethyl stearate, 6-11.5 parts of moisture-proof compound, 3-5 parts of imvite, 2.5-9 parts of phosphate ester and 1.2-5.6 parts of polytetrafluoroethylene. The non-woven fabric has the excellent moisture-proof property.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a non-woven fabric with excellent moisture-proof performance. Background technique [0002] In modern times, there are many kinds of synthetic leathers. In addition to the common characteristics of synthetic fiber non-woven fabric base and polyurethane microporous surface layer, all kinds of synthetic leather have different types of non-woven fabric fibers and processing techniques. For example, styrene-butadiene or nitrile latex base impregnating liquid is used to obtain a special combination between non-woven fabric fibers and polymers; the structure has different levels, including 3-layer, 2-layer and single-layer structures; surface embossing and tanning processes are used , Manufacture suede synthetic leather, etc. [0003] The moisture-proof performance of the non-woven base of the existing synthetic leather is not high, and cannot meet the demand of the market. Contents of the inve...
