NOVELTY - Manufacturing antibacterial and breathable compound yarn comprises blending the graphene nylon compound fiber, modal fiber, viscose fiber, bamboo fiber and polytrimethylene terephthalate fiber, adding 1.5% antistatic agent and 1.5% moisturizer before blending, conveying the blended fiber to a cotton box blender, forming into a cotton roll using a roll forming machine with a cotton roll weight of 370-420 g/m, manual proportioning, mixing cotton, opening cotton, carding cotton, mixing cotton continuous weighing quantitative feeding in the mixed cotton bin, softly opening through the negative pressure of the fan, using plunker-HSR1000 drawing frame, where the main parameters of the process are two-combining, the output speed is 240-260 m/minute, the draft multiple is 3-8, and the dry weight of the sliver is 15-18/5 m to obtain better fiber straightness and evenness, the draw roller spacing is 12x 19 mm, the roving weight is 4.2-5.2 g/10 m, and the twist coefficient is 50-60. USE - The method is useful for manufacturing antibacterial and breathable compound yarn. ADVANTAGE - The yarn has good antibacterial permeability. The method: is simple and fast; obtains beautiful finished product; and has high economic value. DETAILED DESCRIPTION - Manufacturing antibacterial and breathable compound yarn comprises blending the graphene nylon compound fiber, modal fiber, viscose fiber, bamboo fiber and polytrimethylene terephthalate fiber, adding 1.5% antistatic agent and 1.5% moisturizer before blending, conveying the blended fiber to a cotton box blender, forming into a cotton roll using a roll forming machine with a cotton roll weight of 370-420 g/m, manual proportioning, mixing cotton, opening cotton, carding cotton, mixing cotton, continuous weighing and quantitative feeding of the mixed cotton bin, softly opening through the negative pressure of the fan, using plunker-HSR1000 drawing frame, where the main parameters of the process are two-combining, the output speed is 240-260 m/minute, the draft multiple is 3-8, and the dry weight of the sliver is 15-18/5 m to obtain better fiber straightness and evenness, and the draw roller spacing is 12x 19 mm, the roving weight is 4.2-5.2 g/10 m, the twist coefficient is 50-60, the draft multiple is 1.2-2 times, the roller gauge is 25x 35 mm, the CV value of the roving sliver is 5-5.5%, and using JWFl 562E ring spinning machine, where the roller speed is 230-240 revolution per minutes, using the anti-static carbon black rubber roller, the drawing multiple is 1-3 times, and the twist coefficient 340-380 twist/minute. An INDEPENDENT CLAIM is also included for antibacterial and breathable compound yarn, comprising 60-80 pts. wt. graphene nylon compound fiber, 8-16 pts. wt. bamboo fiber, 8-12 pts. wt. viscose fiber, 10-18 pts. wt. modal fiber, and 10-18 pts. wt. polytrimethylene terephthalate fiber.
