Technical Field

[0001] The invention relates to the technical field of textile materials, in particular to a manufacturing process and device for antibacterial cashmere knitted yarn. Background Art

[0002] Cashmere fibers are prone to bacterial growth due to their strong hygroscopicity. Traditional antibacterial finishing (such as chitosan and quaternary ammonium salts) has problems such as poor durability or affects the feel. Although nanosilver has broad-spectrum antibacterial properties, it is prone to aggregation or loss when directly loaded.

[0003] The existing technology has not solved the problem of efficient combination of cashmere fiber and nanosilver and the adaptability of spinning process. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a manufacturing process and device for antibacterial cashmere knitting yarn.

[0005] The present invention provides a process and device for manufacturing antibacterial cashmere knitted yarn, comprising the following steps: Step 1: Carboxylation modification of cashmere is performed using 1,2,3,4-butanetetracarboxylic acid (BTCA) to activate its surface; Step 2: Mix the cashmere and nanosilver solution in a specified ratio; Step 3: Dry in oven at 85℃ for 3min → bake in setting machine at 160℃ for 2min → rinse thoroughly with water at room temperature → dry at 80℃ for 3min Step 4: Use a two-pass drawing method to prevent static entanglement during the production process; Step 5. The cashmere fiber is processed into coarse yarn using a roving machine, and then the fiber is processed into fine yarn using a spinning machine; BTCA introduces carboxyl groups on the cashmere surface to enhance the nanosilver binding sites, which are then baked and fixed to form a cross-linked structure at high temperature to ensure antibacterial durability and antistatic spinning. The two-step drawing process reduces production losses, retaining the cashmere's fineness, softness and warmth, good drape, non-pleating properties, elastic stretchability, texture, good moisture absorption, breathability and hydrophilicity. At the same time, the cashmere increases its antibacterial properties with the cooperation of nanosilver while keeping its weight light.
