Whole water-repellent natural fiber spunlace non-woven fabric and production equipment thereof

Abstract

The invention discloses a whole water-repellent natural fiber spunlace non-woven fabric. The whole water-repellent natural fiber spunlace non-woven fabric comprises a natural fiber spunlace non-wovenfabric, wherein the surface of the natural fiber spunlace non-woven fabric is coated with a water-repellent layer; holes are formed in the natural fiber spunlace non-woven fabric and the water-repellent layer in a penetrating way. The invention also discloses the whole water-repellent natural fiber spunlace non-woven fabric and production equipment thereof. The production equipment comprises single-side equipment with a liquid coating layer, a tension control mechanism, a drying machine, a perforating machine, and a coiling machine, wherein the single-side equipment with the liquid coating layer comprises a liquid tank and a liquid coating roll; the liquid tank is used for containing a water-repellent mixed solution of a water repellent, an enhancer and water; one part of liquid coating roll is soaked into the water-repellent mixed solution. The whole water-repellent natural fiber spunlace non-woven fabric has the advantages that the reverse osmosis can be avoided, and the comfortability and hydrophilia are guaranteed.

Description

technical field [0001] The invention relates to the technical field of weaving, in particular to a fully water-repellent natural fiber spunlace nonwoven fabric and production equipment thereof. Background technique [0002] At present, sanitary napkins are usually made of natural fibers, because natural fibers have good air permeability and hydrophilicity. However, due to the extremely high reverse permeability of natural fibers, which is 20 times higher than that of ordinary non-woven fabrics, reverse osmosis will occur during use, resulting in frequent menstrual blood remaining on the surface of sanitary napkins, affecting comfort. If non-woven fabrics are used as raw materials for sanitary napkins, although there is no problem of reverse osmosis, their hydrophilicity and air permeability are poor, and their comfort is low. [0003] In order to solve the above-mentioned technical problems, this case arose. Contents of the invention [0004] The purpose of the present i...
