Problems solved by technology

[0003] At present, the padding method, coating method and dipping method are mostly used in textiles to achieve antibacterial effect. However, in the traditional method, the antibacterial substances are chemical toxic and harmful substances, which may cause potential damage to the body or the antibacterial substances in the fabric. In the current situation of easy wash-off and long-lasting antibacterial, the use of green non-toxic antibacterial agents and long-term antibacterial and anti-mildew on textiles is a hot topic in the current textile industry research

Abstract

The invention relates to a preparation method of graphene antibacterial yarn. The prepared graphene oxide solution is poured into a dip tank, a vibrator at the bottom of the dip tank is turned on, and the padding coating is completed after the yarn is immersed in the dip tank for a preset time. , semi-drying; adding a photoinitiator to the prepared cinnamaldehyde solution, immersing the treated graphene yarn in the mixed solution, heating up and performing low-frequency ultrasonic vibration for a preset time, and placing it under a certain intensity of ultraviolet light to illuminate, The yarn is taken out for natural cooling, dried, shaped and wound to obtain graphene antibacterial yarn. The product prepared by the invention has bacteriostasis, heat preservation, double bacteriostasis and antiseptic ability, improves the peculiar smell produced by long-term storage of the yarn, and has deodorizing effect; the green and non-toxic additive of ultraviolet cross-linking method makes the components of graphene and cinnamaldehyde more firmly fixed On the yarn pores and surface, it is not easy to wash off during storage and later use, and the antibacterial aging effect is longer; the operation process is relatively simple and convenient, and it has a wider application space.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a preparation method of graphene antibacterial yarn. Background technique [0002] In modern society, in order to meet the needs of people's lives, there are many kinds of textiles, most of which are prone to mildew caused by the germination of mold spores and the growth and reproduction of mycelium on textiles, especially in the case of rainy weather in the south, not only textile products And the storage of raw materials has become a problem, and the mildew-proof storage of textile products has also become an important difficulty in people's lives. [0003] At present, the padding method, coating method and dipping method are mostly used for processing and finishing in textiles to achieve antibacterial effect, but the traditional methods exist that the antibacterial substances are chemically toxic and harmful substances that may cause potential damage to the body or ...
