Embodiment 1

[0038] This embodiment provides a spinning process for improving the cohesion between fibers of cotton-wool blended yarn and the obtained cotton-wool blended yarn. The spinning process provided comprises the following steps:

[0039] S1. Put the wool fiber in an environment with a temperature of 60°C and an ultrasonic power of 215W for 0.40h; place the cotton fiber in an environment with a temperature of 70°C and an ultrasonic power of 240W for 0.65h; the corresponding test performance As shown in Table 1 and Table 2 below:

[0040] Table 1

[0041]

[0042] Table 2

[0043]

[0044] S2. Use the FA002 type automatic plucking machine to pluck the wool fiber after the ultrasonic treatment in the step S1; and use the A035A cotton blender to mix the wool fiber after the pluck; and then use the FA106B cotton opener to use Carding drum, control the output speed to 480rpm, and open the cotton; adopt FA141 single beater lapping machine, use card pin beater, control the fixed a...

Embodiment 2

[0052] This embodiment provides a spinning process for improving the interfiber cohesion of cotton-wool blended yarn and the obtained cotton-wool blended yarn. The spinning process provided is in accordance with the spinning process in Example 1, only step S1 The ultrasonic treatment parameters of the wool fiber are set as follows: ultrasonic power is 230W, the temperature is 55°C, and the time is 0.5h; the ultrasonic treatment parameters of the cotton fiber in step S1 are set as: ultrasonic power is 230W, the temperature is 80°C, and the time is 0.8h; the corresponding test performance is shown in Table 3 and Table 4 below:

[0053] table 3

[0055] Table 4

[0056]

[0057] Finally, a cotton-wool blended yarn with a fineness of 30.0tex and a twist of 65.0 twist / 10cm was prepared.

[0058] After testing, the breaking strength of the cotton-wool blended yarn prepared in this example is 311.7N, and the breaking elongation is 5.05%.

Embodiment 3

[0060] This embodiment provides a spinning process for improving the interfiber cohesion of cotton-wool blended yarn and the obtained cotton-wool blended yarn. The spinning process provided is in accordance with the spinning process in Example 1, only step S1 The ultrasonic processing parameters of the wool fiber are set as follows: ultrasonic power is 200W, the temperature is 65°C, and the time is 0.5h; the ultrasonic treatment of the cotton fiber in step S1 is: ultrasonic power is 250W, the temperature is 80°C, and the time is 0.5h ; The corresponding test performance is shown in Table 5 and Table 6 below:

[0061] table 5

[0062]

[0063] Table 6

[0064]

[0065] The final prepared cotton-wool blended yarn has a fineness of 29.5tex and a twist of 60.0 twist / 10cm.

[0066] After testing, the breaking strength of the cotton-wool blended yarn prepared in this example is 304.8N, and the breaking elongation is 5.24%.

Abstract

The invention discloses a spinning process for improving cohesive force between cotton-wool blended yarn fibers. The spinning process comprises the following steps: S1, placing wool fibers in an environment with the temperature of 55 to 65 DEG C and the ultrasonic power of 200 to 230 W for ultrasonic treatment; and placing cotton fibers into an environment with the temperature of 60 to 80 DEG C and the ultrasonic power of 230 to 250 W for ultrasonic treatment; S2, respectively performing cotton opening, cotton carding and drawing procedures on the wool fibers and the cotton fibers which are subjected to ultrasonic treatment in S1; and S3, performing mixed drawing, roving, spinning and spooling procedures on the wool fibers and the cotton fibers which are drawn in S2, to obtain cotton-wool blended yarns. The cohesive force between the cotton fibers and the wool fibers in the finally prepared cotton-wool blended yarn is perfect, and the mechanical property of the cotton-wool blended yarn is excellent.

Description

technical field [0001] The invention belongs to the technical field of cotton-wool blended yarn, and in particular relates to a spinning process for improving cohesion between fibers of cotton-wool blended yarn. Background technique [0002] Wool fiber is favored by consumers for its excellent comfort and good dyeing performance, but due to its high production cost, wool fiber is blended with other textile fibers to reduce production cost. Because cotton fiber also has good moisture absorption and sweat-conducting properties and a relatively complete color spectrum, it becomes a more suitable fiber material for blending with wool fiber. And a very important key issue of blending wool fiber and cotton fiber is exactly the cohesion force between fibers, and the cohesion force between fibers affects the quality of blended yarn to a great extent. [0003] At present, the method of improving the cohesion between fibers of blended yarns is mainly through waxing the yarns and incr...
