Production practice of antibacterial and warm carbon-silver composite fabric
- Dec 05, 2018 -

Introduce the development process of antibacterial thermal insulation carbon silver composite fabric. Adding activated carbon powder and silver powder to the PU resin, the silver powder can make the product have excellent heat storage and warmth and superior metal appearance. The carbon powder can make the textile have antibacterial, antibacterial, heat storage and warmth effects, and will contain carbon powder and silver powder. The PU resin is embossed on the surface by OPP transfer film, and the carbon silver film is transferred onto the woven four-sided elastic fabric. The antibacterial and warm carbon silver fabric is developed by optimizing the process parameters. According to various standards, the fabric is hot. The resistance can reach 0.013m2·K/W, the moisture resistance reaches 25.1m2·Pa/W, the inhibition rate is over 90%, and other indexes meet the requirements.

With the development of the economy and the needs of life, the functionality of clothing continues to expand in real life, and the requirements for functional textiles are becoming more and more demanding. Functional fabrics with antibacterial deodorization and heat storage are popular. Antibacterial textiles currently on the market generally use an antibacterial finishing agent to finish the fabric, such as silicone-quaternary ammonium salt, which forms a good chemical bond with the fiber on the surface of the fabric, so that the fabric obtains a good antibacterial effect. The diphenyl ether antibacterial finishing agent is a non-ionic white slurry. The slurry is relatively easy to disperse in water and can be used in the finishing process of socks, underwear, towels, shirts, sportswear, bedding, curtains, handkerchiefs and carpets. . In recent years, organic nitrogen antibacterial finishing has also received attention.

Another method is to carry out deodorant finishing. Since the fabric is a porous material, it can adsorb various forms of impurities on the surface quickly, which is easy to cause bacteria to multiply and produce various tastes. Therefore, many fabrics use an odor absorbent. For example, activated carbon has a strong adsorption effect on odor [1–3]. These antibacterial finishings have the disadvantages of long process flow, high cost, and poor environmental protection. Therefore, an antibacterial thermal processing method with short process, low cost and environmental protection is urgently needed.

1 raw materials and test methods

This product development uses PU resin to add activated carbon powder and silver powder to the surface of woven fabric. Silver powder can make the product have good heat storage and warmth and super strong metal appearance. PU resin with carbon powder and silver powder is passed through OPP transfer film. The fabric printing is carried out, and the carbon silver film is transferred to the woven four-sided elastic fabric in combination with the hot stamping process, so that the fabric has the characteristics of heat storage, heat preservation, antibacterial and deodorization, and also has the advantages of fashion, friction coefficient, wind resistance and elasticity. Features. 1.1 Selection of raw materials 1.

1.1 Basic specifications of base fabric and other raw material base fabric: width 160cm, 75D four-sided elastic, (75D+40D) × (75D+40D), surface density 105g/m2, blending ratio T/op94/6, transmissive 480 Root/10cm, weft density 430/10cm, fabric tissue is 1/1 plain weave.

1.1.2 Silver powder and carbon powder Silver powder is commonly known as “aluminum powder”. It is light in weight, high in floating force, strong in hiding power, good in reflection performance against light and heat, and can also make derivatized textiles have heat storage and warmth. And a super metallic look. The carbon powder material is biological material, which is non-toxic and harmless. The addition of carbon powder to PU resin can make the fabric have the functions of good hygroscopicity, deodorization, antibacterial and antibacterial, anti-ultraviolet rays, far infrared rays, heat storage and warmth [4, 5].

1.2 Processing Process The production process of antibacterial and warm carbon silver fabric is as follows: carbon silver film: sizing→semi-baked carbon silver film+base cloth: heating and laminating→cooking cooling→winding→peeling→finished product

1.3 Performance test The appearance of washing is tested according to the standard AATCC124-2011; the soaping fastness is tested according to AATCC61-2013; the abrasion resistance is tested according to ASTM D4966-2010; the tearing strength is tested according to STMD1424-2009 The fabric insulation value is tested according to GB11048-2008; the inhibition rate is tested according to GB/T20944.3-2008.
