Description

Beam warping machine for warping diaphragm yarn

Technical Field

The invention relates to the technical field of textile machinery, in particular to a beam warping machine for warping diaphragm yarns.

Background

The current production of warp knitting for clothes is particularly seriously limited by raw materials, and the raw materials with beautiful appearance but poor knittability can hardly be applied to warp knitting. For example, flat membrane yarns, gorgeous fancy yarns, metallic yarns, colorful yarns and the like are applied to clothing warp knitting products, mainly the warp knitting products have poor knitting performance, and the warp knitting products have poor expressive force, so that warp knitting manufacturers are required to test brand-new process flows according to the characteristics of the yarns, and special yarns can exert the maximum expressive force in clothing warp knitting products.

Recently, a type of thin film yarn with high light reflection degree appears in the yarn market, the yarn is divided into a single-layer coating film, a double-layer coating film and a colorful film, the yarn can be cut into different sizes according to the requirements of users, and the color of the yarn can be selected by the users.

The specific approximate data of the membrane yarn are as follows: the cross section is a flat rectangle, the width of the cross section is 200 and 400 microns, and the thickness is 20-40 microns. The total titer is 70-150D, the elongation at break is 80-160%, the breaking strength is 60-180 cN, and the breaking strength is 0.7-1.6 cN/dtex.

The yarns have strong light reflection performance, and in order to fully express the characteristics of the yarns in the fabric, the yarns are required to be arranged in the fabric in a mirror-like manner, the turnover rate of the membrane yarns is low, and otherwise, the light reflection degree is influenced. In order to solve the problem of the turnover, the yarn cannot be turned over when the diaphragm supplies the yarn, and therefore, warping the yarn becomes a necessary option. However, the ordinary beam warping machine cannot be directly used, needs to be modified, and can prevent the yarn from being automatically twisted during unwinding, and a common method adopts a passive rotating wheel unwinding mode, so that the yarn can be supplied in a non-twisting mode, but the yarn cannot be ensured due to the influence of various reasons, the warping quality is poor, the edge collapse is easy, the yarn tension is uneven, and the yarn is deformed irreversibly due to large local tension force. In addition, the limitation of unwinding mode makes the machine speed slow, tension control difficult, and the easy broken yarn leads to production inefficiency. In severe cases, the machine is difficult to start after the pattern shaft is arranged on the machine, and the quality of the pattern shaft seriously affects the quality of fabrics and the weaving efficiency.

The yarn tension adjusting and controlling method of the common beam warping machine comprises the following steps: after the yarns are hung on a creel of a beam warping machine, the yarns are threaded according to a yarn-passing path, tension is preset on the creel of the beam warping machine according to varieties (a hook-and-loop type common tensioner is used for changing friction force between a loop and the yarns by using the change of a hook loop so as to achieve the purpose of applying different passive tensions to the yarns), then the machine is started at a slow speed, then a handheld tension tester is used for carrying out tension test on each yarn, the hook-and-loop debugging is carried out on the tensioner when the tension value does not reach the standard, after all the yarns are debugged, the machine is started again for carrying out beam warping production, and after the varieties are changed, the previous operation is continued. The yarn control has no intermediate real-time control, is not suitable for finishing high-requirement membrane yarns, cannot automatically adjust the tension, and is not suitable for yarns with high requirements on the tension. Of course, the yarn can not be stopped in time due to sudden large tension change caused by special reasons.

How to normally apply the film yarn in the clothing warp-knitted products becomes the technical attack direction of manufacturers with the super-thick technical level. The warping technology research of the diaphragm yarns also becomes a very important part, the improvement of the warping technology provides conditions for smooth large-scale production of the diaphragm yarns, the improvement of the warping quality and efficiency indirectly reduces the weaving difficulty, preconditions are provided for the improvement of the weaving quality and efficiency, and good conditions are provided for the wide application of the diaphragm yarns in fabrics. Of course, the smooth large-scale application of film yarns has also directly contributed to the emergence of this patent and a series of technical patents.
