Abstract

The invention relates to the technical field of spinning, and in particular relates to an antibacterial yarn and a spinning process thereof. By modifying natural chitin, obtained modified chitin fibers are high in strength and good in cleanliness and thermal stability, and the antibacterial property of the modified chitin fibers is reserved; meanwhile, an emulsified oil agent and an antistatic agent are adopted, so that the antistatic property, softness and fiber cohesive force of the modified chitin fibers are improved, and the using effect of the modified chitin fibers is further improved; the modified chitin fibers are blended with cotton fibers, so that the strength of the antibacterial yarn is further improved; and meanwhile, reagents required by the method are common and low in price, so that the cost of the whole process is reduced.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to an antibacterial yarn and a spinning process thereof. Background technique [0002] From the antibacterial technology of textiles, there are mainly two types, one is antibacterial finishing, and the other is antibacterial blend spinning. In the past, post-finishing processing technology was often used or organic substances such as quaternary ammonium salts and silicones were added to the spinning oil, or coated on the surface of the fabric, but the antibacterial components gradually fell off with the washing of the fabric, and the antibacterial durability was poor. Blended spinning is a physically modified spinning method. In the polymerization process, antibacterial materials are introduced to make them evenly dispersed and combined in the spinning chips. Long and short filaments can be spun on ordinary spinning equipment without additional equipment. , is a real antibacterial...
