[0001] The present application relates to the technical field of chenille yarns, and in particular to an antibacterial chenille yarn and a production process thereof. Background Art

[0002] Chenille, also known as velvet, is a new type of fancy yarn. It uses two strands as the core thread and is spun by twisting the feather yarn in the middle. Generally, there are chenille products such as viscose / nitrile, cotton / polyester, viscose / cotton, nitrile / polyester, and viscose / polyester. Chenille decorative products can be made into sofa covers, bedspreads, bed blankets, table blankets, carpets, wall decorations, curtains and other interior decorative accessories. Chenille has the advantages of gorgeous appearance, soft and comfortable, good light blocking, good warmth retention, strong wear resistance and easy cleaning, but it also has certain disadvantages, such as relatively poor moisture absorption and breathability, easy to sweat, which leads to bacterial growth, affecting comfort and hygiene. Therefore, an antibacterial chenille yarn and its production process are proposed. Summary of the invention

[0003] The purpose of this application is to solve the technical problem that the moisture absorption and air permeability are relatively poor, which leads to sweating and then causes bacteria to grow, affecting comfort and hygiene.
