Abstract
The invention relates to a preparation method of an antibacterial anti-yellowing regenerated cellulose fabric. The method comprises the following steps: preparing yarns modified by the anti-yellowing finishing agent, preparing beta-CD/yarns, preparing antibacterial yarns, and preparing antibacterial anti-yellowing regenerated cellulose fabrics. The method is environment-friendly, simple in process and low in cost, and the prepared fabric has good yellowing resistance and antibacterial property and has good application prospect in the textile industry.
Description
Technical Field
The invention belongs to the technical field of textile functional finishing, and particularly relates to a preparation method of an antibacterial anti-yellowing regenerated cellulose fabric.
Background
The regenerated cellulose fiber is a cellulose fiber, is harmless to the ecology and the environment, and is green and environment-friendly. It combines the luxurious texture of natural fiber and the practicability of synthetic fiber into one, has the performances of soft cotton, silk-like hand feeling, lightness, thinness, air permeability and the like, and has bright and full fabric color. Can be blended and interwoven with various fibers (such as cotton, hemp, silk and the like) so as to improve the quality of the fabrics and achieve better using effect of the clothes. However, the regenerated cellulose fabric is liable to have a surface yellowing phenomenon, such as heat setting, due to the action of light, high temperature, chemicals, etc. during wet finishing processing and taking. If the white and light-colored fiber fabrics such as high-temperature film pressing and the like are not subjected to anti-yellowing finishing, yellowing is easy to occur, the aesthetic feeling is influenced, the service life is greatly reduced, and the performance of the fabric is finally influenced. Therefore, in order to solve the color difference generated before and after finishing of white and light-colored fiber fabrics, anti-yellowing treatment is required, at present, anti-yellowing finishing is mostly concentrated on the nylon fabrics, and most of anti-yellowing agent products used for finishing of nylon/ammonia elastic fabrics in the market contain Adipic Dihydrazide (ADH), the ADH has active chemical performance, can perform acylation reaction with aldehyde and also can be used as a formaldehyde catching agent, the formaldehyde content of the fabric exceeds the standard, and the fabric is not easy to be used in the aspect of clothing, so that the anti-yellowing finishing agent without ADH is required to be developed to be finished on the cellulose fabrics.
Textile and clothing easily become a habitat of pathogenic bacteria, not only generate unpleasant odor, but also easily spread diseases and influence the health of people, so the development of antibacterial textiles is very important. The textile antibacterial agent is selected from quaternary ammonium salt, PHMB, triclosan, carrier silver ions, imidazoles, isothiazolinone, zinc pyrithione, carbendazim, cuprous oxide, natural antibacterial agent (mint), permethrin, metal material (silver, copper, zinc, aluminum), etc. The antibacterial agent is arranged on the fabric, so that the growth of microorganisms on the textile can be reduced, the microorganisms on the textile are prevented from polluting human bodies and the environment, and the disease transmission caused by microbial infection is reduced. Among many antibacterial agents, metal ion antibacterial agents have been widely studied because of their excellent antibacterial effects. Silver ion antibacterial fiber has been widely used, but the cost is high and the reaction rate is low. Copper is not only metabolized by the human body but also has an excellent bactericidal effect due to its very high sensitivity to microorganisms. Copper ion compounds tend to be darker in color, limiting their use as antimicrobial agents. The beta-cyclodextrin molecule has the characteristics of hydrophilicity outside the cavity, inclusion property of the cavity to drug molecules, metal ions and other guest molecules, a large amount of hydroxyl active groups inside the cavity and the like, so that the beta-cyclodextrin finished fabric has great potential application value in the field of antibiosis.
