Problems solved by technology

However, since one of the drafting passages is formed by the rear roller and the front roller, and is affected by the middle roller, the distance between the rear roller and the front roller cannot be effectively reduced. The distance between the front and rear gripping points of this drafting passage It is much larger than the other drafting channel. For short-fiber spinning, the distance between the front and rear gripping points in the drafting zone must match the length of the fiber, so that the fiber speed change points during the drafting process are consistent and stable, and uniform drafting is obtained. Therefore, although the two drafting channels with unequal distances in this patent realize the independent drafting of the two drafting channels, one of the drafting channels with a large distance cannot achieve the ideal drafting effect

[0048] Table 1 Spinning process of two-color gradient yarn

[0049]

[0050] The density of white roving and black roving thread is 400tex, and the white roving and black roving are fed in the spinning process order in Table 1, and the spinning 19.4tex two-color gradient yarn is made, and the twist coefficient of Tex is α tex =360, spinning spindle speed 8000rpm, front roller diameter 27mm, double channel rear roller diameter 27mm, front and rear roller spacing 20mm.

[0051] The yarn is woven into a weft knitted fabric, woven by a 14G computer flat knitting machine, the fabric is organized with 1+1 rib, the number of needles is 262 stitches, and the average coil length is 0.56mm. Two-color gradient yarn weft knitted fabric such as Figure 10 as shown.

Embodiment 3

[0053] The technical problem to be solved by the present invention is to provide a single stretched area of equal spacing double channel ring spinning apparatus, in particular involving a ring spinning two roving independent stretch spinning spinning color-changing yarn spinning method. The present invention by designing a rear roller and a rear upper rubber roller having two coaxial independent degrees of rotation of freedom, a double channel upper pin having a rear pressure bar, a double channel down pin, an agglomeration spinning air flow guide and a double channel agglomeration spinning negative pressure suction groove, forming two ring spinning devices having a single stretch zone equal space independent drawing channel. Realize the spinning of two-component color-changing yarn by ring spinning machine, and realize the design of the full spindle number device, which can be modified on the ordinary ring spindle spinning machine at low cost and convenient.

Abstract

The invention belongs to the technical field of ring spinning, and relates to an equal-gauge dual-channel ring spinning device with a single drafting area. The double-channel rear roller, the double-channel rear upper rubber roller, the double-channel upper pin and the double-channel lower pin are designed, the double-yarn-guide pressure bar and the improved compact spinning device are arranged, two independent single drafting areas with equal spacing are obtained, and independent drafting and on-line variable drafting of double roving are achieved. The positions of a middle roller and a rear roller of a traditional compact spinning frame can be borrowed by the two-channel rear roller and the loop gear ring driving shaft, a roller stand of a drafting device of an original spinning frame does not need to be replaced, the original middle roller can be replaced by the two-channel rear roller, and the original rear roller can be replaced by the loop gear ring driving shaft. And a double-channel lower pin, a double-channel rear upper rubber roller, a double-channel lower pin, an upper leather ring, a lower leather ring and the like are replaced. The change of the output quantity of the two rovings is realized by adjusting the draft multiples of the two draft channels on line, and the two-component color-changing yarn is spun. The device is flexible and has strong applicability.

Description

Technical field [0001] The present invention belongs to the field of ring spinning technology, relates to a single stretch zone of equal space two-channel ring spinning device. Background [0002] Ring spinning multi-roving feeding was first marked by the cyro spinning technology, the purpose of the cyro spinning technology is to converge and twist into yarn through two bundles of fibers of a certain spacing, to obtain less hairy feathers, high strength, and high-quality yarn with strand effect, the method is to feed two rovings of the same specification at a larger spacing after the ring spinning, the two rovings go through the same stretching area, and then output at the same time in the front roller jaws, converging and twisting into yarn. [0003] On the basis of feeding multiple raw materials, it is hoped to achieve independent stretching of each raw material. Publication No. 2000-110035 of the Japanese patent (filing date April 18, 2000) discloses a coaxial 3 degrees of fre...
