Problems solved by technology

However, due to the inconsistent fiber properties of cotton fiber and wool fiber, the temperature and humidity of the fiber to the environment and the hardness and material of the drafting components are different when spinning cotton and wool, the quality of the spun blended yarn is difficult to control. Quota management and high production costs

Embodiment 1

[0032] A spinning method of cotton-wool blended yarn, in which the wool roving and cotton roving are drawn separately and gathered together, then twisted and then wound to obtain a cotton-wool blended yarn; the meeting and gathering refers to the cotton fiber whiskers after the cotton roving is drawn. After the sliver and wool roving are drawn, the wool fiber strands are converged and guided by the converging groove, and are held and output by the gathering roller and the gathering cot roller; twisting refers to the cotton and wool fiber strips held by the gathering roller and the gathering cot , is twisted by the traveler and the spindle, and the spindle speed remains unchanged at 10000rpm;

[0033] Such as figure 1 As shown, the drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of wool roving is independently drafted by drafting mechanism Ⅱ; drafting mechanism Ⅰ and drafting mechanism Ⅱ are independently controlled; the front area of ​​...

Embodiment 2

[0037] A spinning method of cotton-wool blended yarn, in which the wool roving and cotton roving are drawn separately and gathered together, then twisted and then wound to obtain a cotton-wool blended yarn; the meeting and gathering refers to the cotton fiber whiskers after the cotton roving is drawn. After the sliver and wool roving are drawn, the wool fiber strands are converged and guided by the converging groove, and are held and output by the gathering roller and the gathering cot roller; twisting refers to the cotton and wool fiber strips held by the gathering roller and the gathering cot , is twisted by the traveler and the spindle, and the spindle speed remains unchanged at 12000rpm;

[0038]The drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of wool roving is independently drafted by drafting mechanism Ⅱ; drafting mechanism Ⅰ and drafting mechanism Ⅱ are independently controlled; the center distance of the front rollers of draft...

Embodiment 3

[0042] A spinning method of cotton-wool blended yarn, in which the wool roving and cotton roving are drawn separately and gathered together, then twisted and then wound to obtain a cotton-wool blended yarn; the meeting and gathering refers to the cotton fiber whiskers after the cotton roving is drawn. After the wool fiber strands and wool rovings are drawn and guided by the converging bell mouth, they are held and output by the accumulating roller and the accumulating cot; The strip is twisted by the traveler and the spindle, and the spindle speed is constant, which is 15000rpm;

[0043] The drafting of cotton roving is independently drafted by drafting mechanism Ⅰ; the drafting of wool roving is independently drafted by drafting mechanism Ⅱ; drafting mechanism Ⅰ and drafting mechanism Ⅱ are independently controlled; the center distance of the front rollers of drafting mechanism Ⅰ The center distance of the rollers in the rear area is 43mm, the center distance of the rollers i...

Abstract

The invention discloses a spinning method of cotton-wool blended yarn and the cotton-wool blended yarn. The spinning method is as follows: the wool roving and the cotton roving are respectively drawn, converged and gathered, and then twisted and wound to obtain the cotton-wool blended yarn; The count of the cotton-wool blended yarn is a fixed value, the feeding weight ratio of the cotton roving and the wool roving is 60:40-50:50, the length of the cotton fiber is 33-38mm, and the length of the wool fiber is 80-100 mm; the count of the cotton-wool blended yarn obtained by the spinning method of the present invention is 60-80 lbs, and the twist is 700-900 twist / m; the breaking strength of the cotton-wool blended yarn is 400-600 cN / tex, The elongation at break is 10-15%, and the evenness CV value is 8-12%. The spinning method of the present invention spins the cotton-wool blended yarn, and the wool fiber whose length is far longer than cotton fiber can be used, so the count of the spun yarn is higher than that of the cotton-wool blended yarn spun in the prior art, and the breaking strength , elongation at break, yarn hairiness and other performance indicators are far superior to the cotton-wool blended yarn spun by the prior art.

Description

technical field [0001] The invention belongs to the technical field of cotton-wool blended spinning, and relates to a spinning method of cotton-wool blended yarn and the cotton-wool blended yarn, in particular to a method for ring spinning cotton-wool fancy yarn and the ring-spinning cotton-wool blended yarn. Background technique [0002] With the advancement of spinning technology, the suitable range of ring spinning is becoming wider and wider, and the types of raw materials for ring spinning are also increasing. In particular, the development of blended products between different raw materials has broadened the scope of ring spinning. The scope of application of the product. When spinning blended yarns by ring spinning, there are usually two ways of mixing raw materials, one is material mixing and the other is sliver mixing. The so-called material mixing means that different raw materials are arranged in proportion when mixing cotton, and after being grabbed by the cotto...
