Embodiment 1

[0030] The application of an organic zinc ion composite antibacterial agent on home textile fabrics. The fabrics are knitted single jerseys made of 70% polyester and 30% nylon, acid dyes single-dyed nylon, and the gram weight is 140gsm.

[0031] The application process of the organic zinc ion composite antibacterial agent is as follows:

[0032] Step 1: Add soda ash 2% (owf) to water before dyeing, mix well with degreaser 1% (owf), put the fabric into the solution at a liquor ratio of 1:10, heat it at 80°C for 30min, drain the water after treatment .

[0033] Step 2: Preparation of dye solution: mix 0.012% (owf) Lanna Yellow 2R, 0.020% (owf) Lanna Red G, 0.007% (owf) Lanna Blue 2R, 0.5% (owf) acetic acid and 1% (owf) leveling agent is mixed, the pH value of the solution is adjusted to 4.5-5, 0.4% (owf) compound antibacterial agent is added, and the dyeing solution is prepared after mixing evenly.

[0034] Step 3: Put the fabric into the dye liquor obtained in step 2 at a liq...

Embodiment 2

[0037] An application of an organic zinc ion antibacterial agent on a blanket fabric, the fabric is warp-knitted double-sided flannel made of 100% polyester, and polyester is dyed with disperse dyes, and the gram weight is 220gsm.

[0038] The processing flow of flannel fabric is as follows:

[0039] Weaving → Slitting → Cloth turning → White embryo carding → White embryo ironing → Presetting → Hemming → Dyeing → Softening → Dehydration → Cloth arrangement → Drying → Wool drawing → Carding → Finished ironing → Shearing → Shaker → Finished product stereotypes.

[0040] Among them, the organic zinc ion composite antibacterial agent is mainly used in the "dyeing" part of the above-mentioned flannel fabric processing process. The application process in the dyeing process is as follows:

[0041] Step 1: Preparation of dye solution: mix 0.0234% (owf) disperse red, 0.117% (owf) disperse yellow, 0.02527% (owf) disperse blue BR and 0.5% (owf) acetic acid, adjust the pH of the solution...

Embodiment 3

[0045] The application of an organic zinc ion composite antibacterial agent on a unidirectional wet-conducting sports fabric. The fabric is a spandex singlet fabric made of polyester, and the polyester is dyed with disperse dyes. The gram weight is 220gsm.

[0046] The processing flow of spandex jersey is as follows:

[0047] Weaving of wool embryo → pre-forming → pre-treatment → dyeing → reduction cleaning → dehydration → drying → sanding → tenter setting → one-way wet processing.

[0048] Among them, the organic zinc ion composite antibacterial agent is mainly used in the "dyeing" part of the processing process of the above-mentioned spandex jersey, and the application process in the dyeing process is as follows:

[0049] Step 1: Preparation of dye solution: mix 0.4% (owf) disperse red, 2.52% (owf) disperse yellow, 0.56% (owf) disperse blue BR and 0.5% (owf) acetic acid, adjust the pH of the solution to 4-5, 0.5% (owf) compound antibacterial agent is added, and the dye liqu...

Abstract

The invention discloses an application of an organic-metal ion composite antibacterial agent, and relates to the field of textile bacteria resistance. The organic-metal ion composite antibacterial agent has good stability and high temperature resistance and can be processed in the same bath with dye, and finish dyeing and antibacterial processing of fabric simultaneously by heating dyeing in a cylinder. The organic-metal ion composite antibacterial agent comprises organic components and metal ions, wherein the organic components comprise pyridine, quaternary ammonium salt, isothiazolinone, imidazole or biguanide; the metal ions comprise silver ions, copper ions or zinc ion and are combined with the organic components through coordination bonds. The invention aims to provide an antibacterial finishing technology with simple processing technology, shortened production process flow and reduced cost, and the fabric prepared with the antibacterial finishing technology can have the characteristics of good antibacterial property and high safety.

Description

technical field [0001] The invention relates to the antibacterial field of textiles, in particular to the application of an organic-metal ion composite antibacterial agent. Background technique [0002] There are more than 500 kinds of bacteria in the human body. Most of the bacteria enter the mouth and respiratory tract through breathing after birth, and more enter the gastrointestinal tract through food and drinking water, and finally settle in the small and large intestines. A healthy human body has about 1-1.5 kilograms of bacteria. The human body is the base camp of bacteria, and they communicate with people in a harmonious and symbiotic relationship. However, the existence of bacteria also threatens people's life and health. On the one hand, bacteria will decompose organic macromolecular substances such as fat and protein in sweat, and produce smells such as ammonia and fatty acids; and other metabolites caused by acute systemic infection. The main ways of bacterial...
