Problems solved by technology

However, the above-mentioned processing technology has some problems in practical application: the reaction conditions are harsh (such as high temperature, long reaction time), and the cost is high; the equipment used in conventional processing technology is complicated to operate and cannot be terminated at any time; factors such as traditional machinery or high temperature have a negative effect on the product. The performance of wearing is seriously damaged; the utilization rate of antibacterial agents is low; the finishing process is not environmentally friendly, and water resources are seriously consumed; a large amount of additives are added to the antibacterial liquid, which increases the cost of finishing and wastewater treatment, and there are potential safety hazards; There are many control factors and side reactions, and the product quality is not easy to control, etc.

Embodiment 2

[0043] Dissolve 0.5mol methacrylamide and 0.05mol initiator in 100ml water, and react at 70°C for 5min to make oligomer antibacterial liquid. The natural fiber textiles to be treated (cotton fabrics, purchased from Zhejiang Guandong Printing and Dyeing Garment Co., Ltd.) were processed by 100KGy electron radiation, immersed in the above antibacterial solution for 6 hours, taken out, and dried in a dryer at 60°C for 30 minutes. Wash its surface with a large amount of deionized water, after drying, soak it in a 0.5% sodium hypochlorite solution by mass percentage, take it out after soaking for 1 hour, wash it with a large amount of water, and dry it in a dryer at 45°C for 1 hour. Prepare antibacterial pure cotton fabric. The available chlorine content of the antibacterial pure cotton fabric was measured by iodometric method.

Embodiment 3

[0049] Dissolve 0.5mol of acrylamide (structure as shown below) and 0.025mol of initiator in 100ml of water, react at 60°C for 30min, and make a working solution. After the synthetic fiber (polypropylene nonwoven fabric) to be treated is irradiated by 80KGy, immersed in the above working solution for 2 hours, the polypropylene fabric is taken out, and its surface is cleaned with a large amount of deionized water. After drying, soak it in a solution of 0.5% sodium hypochlorite by mass, take it out after soaking for 1 hour, wash it with plenty of water, and dry it in a dryer at 45°C for 1 hour to obtain an antibacterial polypropylene fabric. The available chlorine content of the antibacterial polypropylene fabric measured by iodometric method is 0.14%.

After drying, soak it in 0.5% sodium hypochlorite solution by mass percentage, take it out after soaking for 1 hour, wash it with plenty of water, and dry it in a dryer at 45°C for 1 hour to obtain antibacterial cotton fabric. The available chlorine content of the antibacterial cotton fabric measured by iodometric method is 0.23%.

Abstract

The invention discloses a method for preparing antimicrobial textiles by using an electronic radiation technology. The method comprises the following steps: dipping textiles or coating textiles by antibacterial finishing liquid and then carrying out electronic radiation; or firstly, carrying out electronic radiation on the textiles and then dipping or coating the antibacterial liquid; and baking, washing and carrying out after treatment, so as to prepare antibacterial textiles, wherein the radiation range of electronic radiation is 0-500KGy and corresponding other radiation unit conversion value; an antibacterial agent precursor in the antibacterial finishing liquid can generate free radical through electronic radiation, and can react with other substances through the free radical; and the antibacterial agent precursor can be independently used or used in a mixing manner. According to the method, the reaction can be carried out at normal temperature; the treatment process is simple, and easy to control; the antibacterial agent is high in utilization rate and low in energy consumption; and the antimicrobial textiles prepared by the method are excellent in antibacterial property, and good in wearability.

Description

technical field [0001] The invention relates to the technical field of textile production and processing, in particular to the preparation of high-efficiency, long-lasting and good wearable antibacterial textiles by using electron radiation technology. Background technique [0002] With the development of industry, people's living environment is becoming worse and worse. A large number of pathogenic, mold-causing and harmful microorganisms are easy to breed and spread. Various materials and products such as fibers, paper, paint, rubber, and plastic are the source of their growth, reproduction, and spread. , the excellent substrate for spreading, and the large-scale breeding and spreading seriously threaten human health. The use of long-acting antibacterial materials is the simplest, safest and most effective way to prevent the growth, reproduction, spread and spread of harmful microorganisms. In order to make antibacterial materials achieve long-term effects such as water r...
