Development of antibacterial and deodorant fabrics

At present, international shoemaking production is specialized, and the development of high and new technologies has led to rapid changes in shoemaking materials. The fabrics of cloth shoes, cloth-covered rubber shoes and sports shoes, which are mainly made of textiles, are constantly being refurbished. Many countries are also committed to functional research on the hygienic performance and comfort performance of shoes, especially strengthening the factors that affect the appearance and wearing performance of shoes. Research and development work on textile materials. There are very few factories specializing in the production of shoemaking materials in our country. Textile shoemaking materials are basically by-products of yarn-dyed or woolen textile mills. They have few designs and varieties and poor functionality. There is a certain gap compared with foreign countries. In recent years, my country’s shoemaking industry has developed rapidly. In 1994, the national shoe output reached more than 4 billion pairs. The textile materials required by the shoemaking industry are considerable and occupy a very important position in textile production. To this end, we have developed a new series of antibacterial and deodorant shoe fabrics based on extensive research.

Antibacterial and deodorant fabric

1Production trial
.11 Selection of raw materials Synthetic fiber as a raw material for shoemaking has the advantages of strong wear resistance, easy washing and quick drying, beautiful uppers, and low cost. Therefore, in recent years, foreign shoemaking raw materials have changed from pure cotton to pure spinning and synthetic fiber. The development of cotton blending. The selection of fiber raw materials for shoemaking fabrics should match the fabric structure to achieve the effect of being both strong and wear-resistant, moisture-permeable, comfortable and beautiful to wear. Since we first determine that the fabric structure is a jointed double-layer structure and a warp double-layer structure, Use 21,3/polyester/cotton yarn and 21,2/pure polyester yarn as the surface warp, 21,3/, 21,2/pure cotton yarn as the inner warp, 21,3/, 21,2/polyester/cotton yarn as the weft yarn . In this way, polyester yarn or polyester/cotton yarn is used as the outer warp and weft yarns to interweave to form the surface layer of the fabric, which is strong and wear-resistant; pure cotton yarn is used as the inner warp and weft yarns to form the inner layer of the fabric, which has good moisture absorption and breathability and is comfortable to wear. Weave specifications of LZ fabric In order to make the fabric beautiful and strong and durable, we tried to weave two samples, with the surface warp being 21,3/polyester/cotton yarn, the inner warp being 21,3/pure cotton yarn, and the weft yarn being 21,3/ The polyester/cotton yarn uses a double warp weave with four irregular satin weaves on the surface and inside, and the surface warp is 21`2/pure polyester yarn, the inner warp is 21`2/pure cotton yarn, and the weft yarn is 21`2/ The polyester/cotton yarn uses a jointed double-layer weave with a common square weave and a common twill weave on the inside. This solves the problem of uneven fabric surface caused by inconsistent weaving shrinkage of polyester yarn and cotton yarn. The main technical specifications of the sample are as shown in Table 1 Show.

Doubling ~ Winding ~ Warping ~ Drawing on the heald box ~ Weaving ~ Gray fabric trimming ~ Sorting ~ Warehousing In order to ensure the appearance quality of the fabric and solve the problem of different weaving shrinkage rates of polyester/cotton yarn and cotton yarn, increase the polyester yarn size during warping. / Cotton yarn tension measures, through experiments and exploration, the weight of the polyester/cotton yarn tension ring during warping is 1.5 to 2 times that of pure cotton yarn. In order to ensure smooth lifting of the healds, thin sliders are added between the heald frames.

1.3.2 Finishing process
Gray fabric ~ Refining ~ Antibacterial and deodorizing finishing ~ Shaping, packaging Antibacterial and deodorizing finishing is the key to post-finishing and the key to the hygienic function of the product. We use DC570o antimicrobial treatment agent for finishing. The process is as follows: The refined fabric is soaked in DC57oo aqueous solution for 10 minutes, steam at 120°C for 5 minutes. The adsorption capacity of DC5700 on fabric is 0.8owf. 2Testing and analysis of fabric wearing properties and antibacterial properties
2.1 Wearing properties of fabric
The test results of various indicators of the fabric’s wearing properties are shown in Table 2. The abrasion resistance of the fabric was tested on the Y522 fabric abrasion resistance meter. The average number of abrasion resistance of the fabric when 1 and 2 yarns were broken was 1750 times. Table 2 Taking performance: Vibrate vigorously at 320-340rpm for 1 hour. Calculate the number of viable bacteria before and after oscillation. Calculate the antibacterial rate according to the following formula: Antibacterial rate x 100% A. In the formula: A – the average number of viable bacteria before oscillation. number; B—the average number of viable bacteria after shaking; the antibacterial rates of the sample against Staphylococcus aureus, Escherichia coli, and fungi are all 10. %, the antibacterial and deodorizing function meets the standard requirements for antibacterial textiles in Japan and other countries.
2,2.2 Washing resistance
The fabric was washed ten times in accordance with the FJ-54P-85 standard. After ten times of washing, the antibacterial rate was still 95%. It can be seen that the fabric has good washing resistance. Strength (N) Elasticity (warp + weft) (.) Sample – warp and weft rapid breathability (m3/mZ·sX10-3) 1# It can be seen that the fabric has high wear resistance, strength, good elasticity, moisture permeability and breathability. From the hand feel and visual inspection, it can be seen that the product has a soft texture, full feel, beautiful appearance and unique style.
2.2 Antibacterial properties and washing resistance of fabrics
2.2.1 Antibacterial properties of fabric
We use the bacterial count method to evaluate the antibacterial performance of fabrics. The specific operation is as follows: add the sterilized sample and test bacteria to a flask containing buffer solution, and use a shaker at 25°C
3Conclusion
(l) The shoemaking fabric described in this article uses polyester yarn or polyester/cotton yarn as the outer warp and cotton yarn as the inner warp. It adopts a bonded double-layer structure and a double-warp structure. The polyester yarn and weft yarn are interwoven to form the surface layer of the fabric, and the cotton yarn and weft yarn are interlaced to form the surface layer of the fabric. The fabric is interwoven to form the inner layer of the fabric. The fabric is wear-resistant, moisture-permeable, has good elasticity, is comfortable to wear, has a beautiful appearance, is soft in texture, has a plump hand feel, and has a unique style.
