Description

Warping system for warp knitting and weaving of high count spun staple yarns

Technical Field

The invention relates to the field of warp knitting fabric preparation, in particular to a warping system for warp knitting of high count spun staple yarns.

Background

In the textile field, yarns above 50Ne are generally considered to be high count yarns, with the development of the spinning technology, the spinning and application of high count yarns such as 70Ne/1-100Ne/1 single yarn, 100Ne/2-160Ne/2 folded yarn and even ultra-high count yarn are common, the fabric produced by the high count yarn has fine, soft and flat appearance, and the fabric of the ultra-high count yarn can generate luxurious feeling like silk and has high wearing comfort.

High count yarns and extra-high count yarns have been generally applied and popularized on woven fabrics, domestic factories have been able to produce high-grade poplin cotton shirt fabrics with the warp and weft fineness of 140Ne, and meanwhile, the application of the high count yarns and the extra-high count yarns in weft knitting has begun, for example, high count and high density weft knitting cotton knitted fabric shirts have been introduced in China and Japan. However, the application of the spun staple yarns in warp knitting in the domestic warp knitting industry is well explored for a long time, and a few attempts are mostly limited to the application of the medium-low count yarns below 40Ne, while the warp knitting application of the high count yarns is rarely related, and the main reason is that the application is limited by various performance problems of low strength, low elongation, much flying flowers and the like of the high count yarns.

In order to ensure flexible warping and low strength loss of high count yarns, a tensioner is needed in the warping process, the tensioner in the warping process has the action principle that fluctuation of absorption force of an oil damping cup is utilized, namely, tension fluctuation when yarns are unwound from a yarn barrel is balanced, so that the tension of the yarns is smooth, yarn path part elements of the tensioner of a traditional warp knitting warping machine are fixed porcelain columns and porcelain eyes, materials of the tensioner are fine, a yarn contact surface is small, particularly when a turning wrap angle of the yarn path is small, the generated friction force is very large, the damage to the yarns is increased at the same time, and the tensioner is very unfavorable for warping of the high count yarns.

In order to improve the warp knitting quality of high count yarns, new warping systems and tensioners adapted to the characteristics of the yarns need to be developed.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the utility model provides a warping system that is used for high count spun yarn warp to weave to make, the warping system includes warper and creel, the creel is the V font, and the yarn is followed the creel backing-off and is 135 degrees through the play yarn angle behind the tensioner, and the yarn does not pass through many shelves porcelain eye yarn path mechanism after backing-off from the creel, the nose position of warper is provided with collection silk board, corner roller, lambdoid reed, does not use oiler, multistage minute yarn needle, the device of backing a car, and the warper length sets up to 16M.

Further, the tensioner does not use porcelain eyes and porcelain columns.

Furthermore, a light Teflon guide wheel is arranged in the tensioner.

Further, the light Teflon guide wheel comprises a fixing screw, a guide wheel body, a miniature bearing and an anti-floating ring; the guide wheel body is sleeved on the miniature bearing and is installed inside the anti-floating ring through a fixing screw, and one side of the guide wheel body and the anti-floating ring form a yarn running area in a surrounding mode.

The creels (composed of the spindle frames and the tensioner frames) of the warping machine are arranged in a V shape, so that yarn paths of all yarns are not overlapped after the creels discharge yarns, and the yarns are prevented from being wound; the spindle unwinds and goes out of the creel behind the tensioner, the yarn outlet included angle is set to be 135 degrees (the included angle of the yarn outlet creel of the traditional warp knitting warping machine is generally 90 degrees) so as to reduce friction; after the yarn is discharged from the creel, the yarn does not pass through a multi-gear porcelain eye yarn path mechanism of a traditional warping machine, but directly enters a machine head area, so that the yarn path is simplified, and the friction is reduced. The length of the whole machine used by the warp knitting warping machine is only 16M, which is greatly shortened compared with 34M of the traditional warp knitting warping machine, and the short and flat state of yarn paths is favorable for reducing friction. Meanwhile, the warping machine is simplified in arrangement at the machine head part compared with a traditional warp knitting warping machine, only a yarn collecting plate, a corner roller and a herringbone reed are arranged, and conventional devices such as a oiling device, a multi-stage yarn separating needle and a reversing device are not used, so that yarn paths are effectively simplified, and friction is reduced.

The invention changes 2 fixed porcelain columns and 4 fixed porcelain eyes in a tensioner into a light Teflon guide wheel to avoid overlarge friction, wherein the light Teflon guide wheel comprises a fixed screw, a guide wheel body, a miniature bearing and an anti-floating ring; the guide wheel body is sleeved on the miniature bearing and is installed inside the anti-floating ring through a fixing screw, one side of the guide wheel body and the anti-floating ring form a yarn running area, and yarns pass through the yarn running area. For the warping process, the short yarn path and the light tension of the warping machine can greatly reduce yarn damage and flying caused by yarn friction, and can realize high-quality warping work on short fiber yarns, particularly high-count short fiber yarns.
