Embodiment 1

[0033] Embodiment 1: a kind of preparation method of antibacterial yarn is characterized in that, comprises the following steps:

[0034] S01. Weigh the graphene material, dispersant, wetting agent, and dyeing agent in proportion to water, and ultrasonically disperse them evenly. The composition of each component by weight percentage is: graphene oxide 0.2%, dispersant dodecylbenzene Sodium sulfonate 0.6%, dyeing agent 0%, wetting agent dioctyl sodium sulfosuccinate 0.02%;

[0035] S02. After loosening and removing impurities from the cotton yarn, mix the yarn and the slurry at a mass ratio of 1:10, soak in the slurry at 60° C. for 1 hour, and continuously stir during the soaking process;

[0036] S03, soaping the soaked yarn, then adding color-fixing agent dialkylamino ethyl methacrylate to fix the color, and then dehydrating, the moisture content of the dehydrated yarn is 20%, and finally put it in the Dry at 95°C to obtain antibacterial yarn.

Embodiment 2

[0037] Embodiment 2: a kind of preparation method of antibacterial yarn is characterized in that, comprises the following steps:

[0038] S01. Weigh the graphene material, dispersant, wetting agent, and dyeing agent in proportion to water, and ultrasonically disperse them evenly. The composition of each component by weight percentage is: graphene 0.1%, dispersant sodium lauryl sulfate 0.1%, dyeing agent reactive dye 5%, wetting agent acetylene glycol ethoxylate 0.05%;

[0039] S02. After loosening the cotton yarn and removing impurities, mix the yarn and the slurry at a mass ratio of 1:12, soak in the slurry at 85°C for 3 hours, and continuously stir during the soaking process. After 2.5 hours, add salt dyeing accelerator to accelerate dyeing;

[0040] S03, soaping the soaked yarn, then adding the color-fixing agent polydimethyldiallylammonium chloride to fix the color, then dehydrating, the moisture content of the dehydrated yarn is 35%, and finally It is dried at 100°C to ob...

Abstract

The present invention provides an antimicrobial yarn and a preparation method thereof. The anti-bacterial yarn has the safety, the non-toxicity and the efficient and lasting antibacterial performanceof graphene while realizing the yarn color selectivity and meeting the textile diversity demand. The preparation method of the antibacterial yarn comprises the steps of firstly, ultrasonically dispersing graphene, inserting hydrophilic groups and dyeing groups into graphene groups under the action of hydrogen bonds, covalent bonds and the like, and uniformly implanting antimicrobial graphene groups into a general yarn in situ under the action of soaking and dyeing; secondly, enhancing combination between the antibacterial graphene groups and the dyeing groups and the yarn again under the action of soaping and color fixing; and finally, performing dewatering and drying to obtain the antibacterial yarn. The preparation method has the advantages of simple process, energy saving and high efficiency, can be used for preparing a product with good consistency and stability, is environment-friendly, fully realizes the sustainable development idea of fine chemical engineering and environmentalprotection, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an antibacterial yarn and a preparation method thereof. Background technique [0002] Yarn is a product processed from various textile fibers into a certain fineness, which is used for weaving, rope making, thread making, knitting and embroidery, etc. With the development of society and the improvement of economic level, people pay more attention to their own health and the quality of textiles, but traditional yarns do not have good antibacterial properties, which makes yarns easy to deteriorate and pollute. In order to protect people's health and reduce the risk of diseases caused by bacteria breeding in yarn products, the development of textiles with antibacterial properties has become the focus of current research. [0003] At present, most of the textiles with antibacterial function are added in the finishing of textiles to obtain textiles with antibacterial properties. Co...
