Embodiment 1

[0036] The multi-layer viscose fiber composite spunlace mask base cloth of the present embodiment is prepared by the following method:

[0037] 1) Cut the raw ramie into small pieces with a length of 30-50 mm, soak in water at a temperature of 55° C. for 60 minutes, then take it out, extrude and dehydrate until the water content is 48%, to obtain a softening material;

[0038] 2) Put the softened material obtained in step 1) into a steam explosion device for steam explosion, the steam temperature is 220°C, the explosion pressure is 2.2MPa, the heat preservation and pressure are maintained for 3.0min, the pressure is released and the material is discharged, and the explosion mixture is obtained;

[0039] 3) Immediately place the blasting mixture obtained in step 2) in water at 55°C for ultrasonic dipping to dissolve the colloid. The ultrasonic frequency is 40kHz, and the ultrasonic dipping time is 1.5h. During the dipping process, the agglomerated fibers are broken up , sorting...

Embodiment 2

[0044] The multi-layer viscose fiber composite spunlace mask base cloth of the present embodiment is prepared by the following method:

Abstract

The invention relates to a multilayer viscose fiber composite spunlace mask base fabric and a viscose fiber composite mask. The multilayer viscose fiber composite spunlace mask base fabric is preparedby 1) cutting raw ramie into small sections, and soaking with water to obtain a softened material; 2) carrying out steam explosion on the softened material to obtain an exploded mixture; 3) ultrasonically rinsing the exploded mixture in water, and performing impregnation modification to obtain modified ramie fibers; 4) opening and carding the modified ramie fibers to obtain a ramie fiber web; and5) opening and carding viscose fibers to obtain a viscose fiber web, cross-lapping a layer of the modified ramie fiber web between two or more layers of viscose fiber web, and performing water jet process, dewatering and drying to obtain the base fabric. The base fabric has good dry-wet strength and toughness, and the spunlace composite structure can bear the three-dimensional large-cut-number cutting and subsequent rinsing and lifting processes without damage, tearing or deformation; the base fabric has good air and moisture permeability, is soft and comfortable to touch, has good fitting property, is strong in liquid-retaining capacity and is suitable for producing a three-dimensional cut mask.

Description

technical field [0001] The invention belongs to the technical field of mask base fabrics, in particular to a multilayer viscose fiber composite spunlace mask base fabric, and also relates to a multilayer viscose prepared from the above-mentioned multilayer viscose fiber composite spunlace mask base fabric Fiber mask. Background technique [0002] With the progress of society and the improvement of living standards, beauty and skin care products in personal consumer goods present a strong market growth trend. Among them, facial masks are favored by consumers because of their convenient use, diverse functions, low cost, and obvious skin care effects. The per capita consumption is increasing year by year, and the market scale is huge. Masks are divided into carrier-free masks and carrier-based masks according to the way of use. The latter refers to a mask that uses film-forming materials or fiber materials (mask base fabric) as a carrier and supplemented with nutrients to cove...
