Preparation method of hydroentangled facial mask substrate with high water absorption and high strength

Abstract

The invention relates to a preparation method of a hydroentangled facial mask substrate with high water absorption and high strength. According to the preparation method, firstly, polyester fibers andnylon fibers are blended, and a hydroentangled nonwoven fabric is formed by means of carding, intersected lapping, hydroentangling and reinforcement; then, the hydroentangled nonwoven fabric is subjected to soaking treatment, soaked in a waterborne polyurethane solution and then dried to obtain a substrate semi-finished product; finally, the substrate semi-finished product is dipped in a NaOH solution for alkali minimization treatment to obtain the hydroentangled facial mask substrate. By increasing nylon fiber components, the strength of the facial mask substrate is enhanced, and the water absorption rate of the facial mask substrate is increased; by means of dipping in the high-elasticity waterborne polyurethane solution for soaking treatment, waterborne polyurethane forms a net structure with micropores in a nonwoven fabric substrate, and therefore the water absorption rate and the water retention rate are further increased. By soaking the nonwoven fabric substrate in the NaOH solution, NaOH and polyester fibers of the nonwoven fabric substrate are subjected to a reaction, the rigidity of the polyester fibers is lowered, and the hand feeling and skin fitting performance of thehydroentangled facial mask substrate are improved.

Description

Technical field [0001] The invention relates to the technical field of production and processing of a facial mask substrate, in particular to a method for preparing a hydroentangled facial mask substrate with high water absorption and high strength. Background technique [0002] The mask is a carrier of beauty care products. It is applied on the face for 15-30 minutes. When the nutrients of the care products are slowly absorbed by the skin, the mask is removed. The material of the mask is powdered, kaolin, and non-woven. Masks such as cloth and silk, tencel, and biological fiber. Mask base materials made of synthetic fiber materials generally have low water retention and poor fit; masks made of natural fibers such as silk and biological fibers have poor strength, are easy to tear and deform, or are not easy to peel off due to insufficient elasticity . [0003] At present, the domestic high-end facial mask market is monopolized by a few companies such as Japan and South Korea. Mos...

Problems solved by technology

Mask substrates made of synthetic fiber materials generally have a low water retention rate and poor fit; masks made of natural fibers such as silk and biological fibers are too weak to be easily torn and deformed, or not easy to peel off due to insufficient elasticity

[0003] At present, the domestic high-end facial mask market is monopolized by a few companies such as Japan and South Korea, and most of them use highly water-absorbent silk materials or bio-fiber materials, but the mask strength is poor, and it is easily damaged when used alone, and the material cost is also high. ;The facial masks produced by domestic enterprises are mainly synthetic fiber spunlace cloth substrates, which use ordinary polyester fibers to be reinforced by carding, cross-lapping, and spunlace technology into a grammage of 20-60g / m 2 spunlace mask substrate

The cost of the spunlace mask base material is relatively low, but its longitudinal strength is about 18-20N / 50mm, its transverse strength is about 16-20N / 50mm, and its water absorption rate is 4-4.5g / g (1g base fabric absorbs water 4-4.5 g water), the water retention rate is poor, the elasticity and strength are poor, and it is difficult to improve the grade.
