Problems solved by technology

But above-mentioned novel spinning method still can't adapt to people's requirement to the aspects such as textile raw material, yarn variety, if Sirofil spinning can realize spinning a long filament and a staple fiber roving to have core-spun structure spun yarn, but it is difficult to ensure the wrapping effect of the yarn, that is, the core yarn in the middle is easily exposed; Siro spinning can realize the parallel twist spinning of two roving yarns, but when spinning high-count yarns, due to each The number of fibers in the twisting triangle area of ​​a roving sliver is small, and it is easy to break

Embodiment 1

[0018] Example 1 Spinning a silk-like yarn on a cotton ring spinning frame

[0019] Two cotton rovings a, a' are unwound from the roving bobbin, respectively enter the drafting area through the guide horn 1 in parallel for drafting; two silk b, b' are guided by the positioning guide wire hook or guide wheel to the front roller 5 Back-end feeding, silk b, b' is parallel to cotton roving sliver a, a', wherein silk b, b' runs on the outer side of cotton roving sliver a, a'; two cotton roving sliver after drafting a, a' and two pieces of silk b, b' are output from the front jaws and enter the twisting triangle area to be twisted, and then wound on the spun yarn bobbin 7 after passing through the yarn guide hook 6 . The yarn spun in this way has silk on the surface and cotton yarn on the inner core. The fabrics made of this yarn not only have the style of real silk, but also reduce the cost.

Embodiment 2

[0020] Embodiment 2 spinning wool core-spun yarn

[0021] The two wool rovings a and a' are unwound from the roving bobbin, respectively enter the drafting area through the guide horn 1 in parallel for drafting; the two polyester filaments b and b' are guided by positioning guide hooks or guide wheels Feed from the rear end of the front roller 5, the filaments b, b' are parallel to the wool roving strands a, a', wherein the filaments b, b' run on the inside of the wool roving strands a, a'; Wool roving strands a, a' and two polyester filaments b, b' are output from the front jaws and entered into the twisting triangle area for twisting, and then wound on the spun yarn bobbin 7 after passing through the yarn guide hook 6 . The yarn spun in this way has the surface of wool and the inner core of polyester filament. The yarn has the style and characteristics of wool yarn, but also improves the strength and reduces the cost.

Embodiment 3

[0022] Embodiment 3 spinning ramie high-count yarn

[0023] Two ramie rovings a, a' are unwound from the roving bobbin, respectively enter the drafting zone through the guide horn 1 in parallel for drafting; two fine denier (50-120 denier) polyester filaments b, b' pass through the positioning The guide hook or guide wheel is fed from the rear end of the front roller 5, the filaments b, b' are parallel to the hemp roving strands a, a', wherein the filament b overlaps with the roving a, and the filament b' overlaps with the roving a' Coincident; two ramie roving strands a, a' after drafting and two polyester filaments b, b' are output from the front jaws and enter the twisting triangle area for twisting, and then are wound on the spun yarn after passing through the yarn guide hook 6 On bobbin 7.

[0024] Ramie is difficult to weave high-count yarns due to its thick fibers, high stiffness, and poor cohesion. Although sirofil spinning can be used to spin high-count yarns of more...

Abstract

The invention relates to a method for positioning yarn by an embedded system, belonging to the technical field of textile processing. The method comprises the technical proposal that: on a drafting mechanism of a ring spinning frame, two chopped fiber rough yarns unreeled from a rough yarn bobbin enter a drafting zone respectively in parallel to be drafted by yarn guiding horns; two continuous yarns are fed from the rear end of a front roller, and join with the two crude yarn strands respectively at a front jaw; the two drafted crude yarn strands and the two continuous yarns are output from the front jaw, enter a twisting triangular zone to be twisted, and are wound on a spun yarn bobbin into yarn; according to different relative positions of the two crude yarn strands and the two continuous yarns, yarns with various structures can be formed. The method can realize that polycomponent yarns with a core-spun structure, a fasciated structure and a folded yarn like structure can be spinned on the ring spinning frame; the yarn structure can be accurately selected and determined and is closer, and yarns has more excellent hairiness, brute force and evenness; and spinning of special fiber yarns on the traditional spinning equipment can be realized so as to enlarge the range of spinning materials.

Description

technical field [0001] The invention relates to a spinning method capable of spinning various structural yarns on a ring spinning frame, which belongs to the technical field of textile processing. technical background [0002] With the technological advancement of textile materials and people's increasing demand for clothing fabric styles, the requirements for spinning technology are also getting higher and higher, such as ultra-high-count yarns, multi-component composite yarns, etc., for spinning There are more and more technical researches, and various spinning methods emerge in endlessly, such as sirofil spinning, siro spinning, compact spinning, cable spinning, etc. These new spinning methods have greatly enriched the spinning processing methods. Significantly improved yarn quality. For example: Sirofill spinning can realize the spinning of one filament and one short fiber roving into a spun yarn with a core-spun structure; Siro spinning can realize the parallel twist s...
