Embodiment 1
[0014] A kind of Tencel wool blended yarn production process is characterized in that, described production process comprises the following steps:
[0015] Step 1: Select Tencel fiber and Merino wool with a blending ratio of 70%:30%. The Tencel fiber specification is: 1.4dtex Tencel fiber, and the Merino wool specification is: 17.2mic Merino wool;
[0016] Step 2: After blending, first needle combing, second needle combing, third needle combing, and four needle carding processes, the tencel fiber and merino wool are combined and then drafted to form a roving sliver, and the roving sliver is carded. Make the roving sliver as straight as possible, and the final needle speed is 180m / min, which is conducive to making the sliver evenly mixed and reducing magazines;
[0017] Step 3: The use of shot-medium hard rubber rollers is beneficial to strengthen the control of floating fibers, reduce the twisting triangle area, and improve the yarn quality. The new compact spinning technology...

Abstract
The invention relates to a production process of tencel wool blended yarn. The process is characterized by including the following steps: step I. selecting tencel fiber and merino wool in a blending ratio of 70% to 30%, wherein the specification of the tencel fiber is 1.4 dtex tencel fiber and the specification of the merino wool is 17.2 mic merino wool; step II. through the working procedures ofsliver mixing, first needle combing, second needle combing, third needle combing and fourth needle combing, combining the tencel fiber and the merino wool and then drafting the fiber to form roving sliver, combing the roving sliver to make the roving sliver as straight as possible with a final needle speed of 180-200 m/min; step III. adopting rubber rollers with medium elasticity and hardness, wherein the rubber rollers are conducive to strengthening the control of floating fiber, reducing twisting triangle area and improving yarn quality; and step IV. steaming yarn for three times, treating at 30-60 DEG C for 0.5 hour, and vacuum standing for 30 minute; and after treatment at 85 DEG C for 0.5 hour, vacuum standing for 30 minutes, and finally, treating at 90 DEG C for 0.5 hour. According to the process, the excellent characteristics of the high-proportion tencel wool blended yarn are utilized, the production cost is reduced, and the product quality is improved.
Description
technical field [0001] The invention relates to the textile field, in particular to a production process of Tencel wool blended yarn. Background technique [0002] Blended fabrics are textile products made of chemical fibers mixed with other cotton wool, silk, hemp and other natural fibers. According to the regulations of the International Wool Bureau, a high proportion of Tencel wool blended yarn refers to a yarn blended with a proportion of not less than 50% Tencel fiber. High proportion Tencel blended yarn has been widely used in the field of textile light industry because of its good characteristics. [0003] As the "green fiber of the 21st century", Tencel is the most typical environmentally friendly green fiber. The high proportion of tencel blended yarn can reduce the cost of woolen fabrics due to its good characteristics, without reducing the style of the fabric due to the mixing of other fibers. But in the actual production process, there are many problems. Tenc...
