Problems solved by technology

With the continuous improvement of people's material living standards and their own health requirements, higher requirements have been placed on the comfort of clothing and its materials. Although the moisture regain of wool fiber (about 15%) is higher than that of cotton fiber (about 8 %) is high, but the scale layer of wool causes low moisture absorption rate and cannot absorb sweat in time, resulting in poor comfort
After mercerizing, the hygroscopicity of wool is greatly improved, but there is still the problem of poor quick drying
In addition, most wool fabrics are made of coated fabrics. After the fabrics are coated, the air permeability is reduced. When people wear this kind of clothing for activities, a large amount of sweat cannot be discharged in the form of steam, and a large amount of adsorbed water and a large amount of moisture are formed inside the clothing. Adhesive water makes people feel uncomfortable such as stickiness, stuffiness, etc., so it cannot meet the needs of wool for lasting warmth

Abstract

The invention provides a method for preparing bacterial cellulose modified moisture-permeable wool fabric, comprising the following steps: S1. preparing bacterial cellulose gel film; S2. preparing bacterial cellulose powder; S3. preparing the bacteria obtained in step S2 The cellulose is dissolved in the acetone solution to configure the bacterial cellulose solution; S4. the maleic anhydride modified bacterial cellulose solution will be prepared; S5. the methyl methacrylate is gradually added dropwise to the deionized water to obtain a monomer emulsion, and the The wool fabric is put into the monomer emulsion, and then maleic anhydride modified bacterial cellulose is added, after being fully stirred, an initiator is added to react to obtain the bacterial cellulose modified moisture-permeable wool fabric. The modified wool fabric prepared by the preparation method of the present invention, by grafting bacterial cellulose, the moisture permeability of the fabric is nearly twice that of the ungrafted fabric, and the quick-drying effect is also nearly twice that of the grafted fabric, so that Modification improves the moisture absorption and quick drying properties of wool products.

Description

technical field [0001] The invention relates to the field of moisture-permeable finishing of wool, in particular to a preparation method of bacterial cellulose modified moisture-permeable wool fabric. Background technique [0002] Wool is a high-grade natural textile fiber with many excellent wearing comforts. For a long time, the application of wool in knitted products mainly highlights its warmth retention and elasticity, and it is mostly used as medium-thick autumn and winter clothing materials. With the continuous improvement of people's material living standards and their own health requirements, higher requirements have been placed on the comfort of clothing and its materials. Although the moisture regain of wool fiber (about 15%) is higher than that of cotton fiber (about 8 %) is high, but the scale layer of wool results in a low moisture absorption rate and cannot absorb sweat in time, resulting in poor comfort. After mercerizing, the hygroscopicity of wool is grea...
