The invention relates to a hygroscopic, breathable and antibacterial ultra-high molecular weight polyethylene blended core spun yarn and a production method thereof. The yarn consists of a core yarn and a cladding yarn, wherein the core yarn is an ultra-high molecular weight polyethylene filament double-twisted yarn; the cladding yarn is a blended yarn consisting of the following three components: 55 to 65 percent of bamboo fiber, 25 to 30 percent of long lint cotton and 10 to 15 percent of terylene; the weight of the cladding yarn is 1.5 to 2 times that of the core yarn. A process for producing the yarn comprises the following steps of blending the bamboo fiber and the terylene fiber, and manufacturing the bamboo fiber and the terylene fiber into a first cotton roll; manufacturing the long lint into a second cotton roll; manufacturing the first cotton roll into card slivers; manufacturing the second cotton roll into combing slivers; manufacturing the first card slivers and the combing slivers into drawing slivers through three drawing procedures, manufacturing drawing slivers into roving; double-twisting ultra-high molecular weight polyethylene filaments into a double-twisting yarn; taking the roving as the cladding fibers, taking the double-twisting yarn as the core yarn, and manufacturing the roving and the double-twisting yarn into the blended core spun yarn. The advantages of high strength, high modulus and good protecting performance of the core yarn, the advantages of moisture absorption, breathability, bacterium resistance and ultraviolet radiation resistance of the bamboo fiber, the characteristic of comfort of the cotton and the characteristic of stiff and neat property of the terylene are combined, so that the quality of the finished yarn is better.

The invention provides a making method of antibacterial yarn. The antibacterial yarn is made by blending, by weight, 45%-60% of pineapple leaf fibers, 40%-50% of long-staple cotton and 5%-15% of spandex. The making method comprises the following steps that the pineapple leaf fiber and the long-staple cotton are mixed and made into a first cotton roll in an opening and cleaning process, the first cotton roll is made into first card silver through a cotton carding process, and the spandex is made into second card silver through a cotton opening and carding combination machine, wherein the length of the long-staple cotton is larger than 35 mm, the first card silver is quantified as 15-17 g / 5 m, and the second card silver is quantified as 15-17 g / 5 m; the first card silver and the second card silver are made into drawn silver through a drawing process; the drawn silver is sequentially subjected to a rough yarn process and a spun yarn process, and the antibacterial yarn is made.

The invention relates to a flame-retardant high-temperature resistant pre-oxidized fiber aramid fiber blended yarn and a production method thereof. The blended yarn is composed of 50-90mass% of pre-oxidized fiber chopped fibers and 50-10mass% of aramid fiber 1313 chopped fibers; the production process flow comprises the following steps of carrying out pretreatment on the pre-oxidized fiber choppedfibers and the aramid fiber chopped fibers separately; performing cotton package mixing on the pre-oxidized fiber chopped fibers and the aramid fiber 1313 chopped fibers in an opening picking procedure to prepare cotton rolls; preparing the cotton rolls into carding silvers in a cotton carding procedure; preparing the carding silvers into drawing silvers through two drawing procedures; preparingthe drawing silvers into roving through a roving procedure; preparing the roving into spun yarns through a spinning procedure; and preparing the spun yarns into a pre-oxidized fiber aramid fiber blended yarn spool through a spooling procedure. The method combines the pre-oxidized fiber and aramid fiber 1313 flame-retardant high-temperature resistant advantages, overcomes the shortcoming of poor spinning performance of the pre-oxidized fiber, and the woven pre-oxidized fiber aramid fiber 1313 blended yarn has excellent quality.

The invention discloses an automatic roll changing system. The automatic roll changing system comprises an automatic roll changing device, a transverse moving grabbing device and a conveying device. The automatic roll changing device is fixedly mounted on the back side of a combing machine. The traverse moving grabbing device is disposed above the automatic roll changing device. The conveying device is arranged on one side of the automatic roll changing device in parallel. The automatic roll changing device takes an empty cotton cylinder out of the combing machine and places a spare cotton roll on the combing machine. The transverse moving grabbing device grabs an empty cotton cylinder on the automatic roll changing device onto the conveying device, and grab and place a cotton roll on theconveying device onto the automatic roll changing device as a spare cotton roll.

The invention belongs to the technical field of novel spinning and particularly relates to anion fiber blended yarn. The preparation process of the anion fiber blended yarn comprises the following steps: pretreating cotton fibers; carrying out blowing-carding on the cotton fibers pretreated in the step one; taking a part of the cotton fibers subjected to blowing-carding to be mixed with anion fibers and making the mixture into a first cotton roll, and taking a part of bamboo fibers to be mixed with the remaining cotton fibers subjected to blowing-carding in the step two and making the mixtureinto a second cotton roll; taking the remaining anion fibers to be mixed with the first cotton roll in the step three and making the mixture into a first card silver, and making the second cotton rollin the step three into a second card silver; and making the first card silver and the second card silver in the step four into a drawn silver through a drawing procedure, and making the drawn silverinto the blended yarn of the anion fibers, the bamboo fibers and the cotton fibers through a roving procedure and a spinning procedure in sequence. The anion fiber blended yarn has the functions of antibacterial sterilization and deodorization, and the preparation process is simple in procedures and easy to operate.
