Problems solved by technology

Although some of these devices are simple in structure and easy to operate, due to the high tension when the filament yarn is fed, it is impossible to achieve equal feeding.
[0004] The invention patent applied and published by the inventor of this patent, such as a wave-absorbing high-elastic yarn and its production equipment and production method (patent application number: 201110242760.X), is directly obtained by using the holding roller in contact with the front roller. The method is effective and practical, but it cannot carry out the intermittent transposition and movement of the filaments; a method for preparing high-elastic composite yarns with non-equal convergence points (p

Embodiment 1

[0038] Using the dual-axis fiber interactive equal-feed composite spinning device of the present invention, after the cotton yarn is equal-fed according to the above method, it interacts with kapok fiber strands to form a two-component equal-feed composite spinning For core-spun composite yarn, the specific process parameters are shown in the table below, wherein the cotton yarn after the holding roller pair 3 is output without tension, and is basically fed into the front roller nip 12 in equal amounts. The spun two-component equal-feed wrapping core-spun composite yarn, because the cotton yarn is periodically transposed and the kapok fiber strands are symmetrically moved left and right, so the appearance of the yarn has an obvious symmetrical and intermittent pattern. The variable wrapping core wrapping effect, see figure 2 11A segment yarn. The composite spinning with wrapping and core-spun periodically alternates has a high yield of yarn, which means that there is very li...

Embodiment 2

[0040] Using the dual-axis fiber interactive iso-feed composite spinning device of the present invention, after the viscose filament is fed by the above-mentioned method, the composite spinning with cotton fiber strands is interactively fed to form a two-component, etc.-feed composite spinning device. The specific process parameters of the wrapping core-spun composite yarn are shown in the table below, wherein the viscose filament after the gripping roller pair 3 is output without tension, and is basically fed into the front roller nip 12 in equal amounts. The spun two-component equal-feed wrapping core-spun composite yarn, because the viscose filaments are randomly transposed and the cotton fiber strands move left and right, so the appearance of the yarn has obvious differences. Asymmetrical, intermittent variable wrapping effect, see figure 2 11A segment yarn. Since the strand shifting mechanism is installed at the rear of the middle roller, the change period of the wrappi...

[0042] Using the dual-axis fiber interactive iso-feed composite spinning device of the present invention, after the polyester filament is fed by the above-mentioned method, the composite spinning is carried out with the wool fiber strands to form a two-component iso-feed type The wrapping core-spun composite yarn, the specific process parameters are shown in the table below, wherein the polyester filament after the holding roller pair 3 is output without tension, and is basically fed into the front roller nip 12 in equal amounts. The spun two-component equal-feed wrapping core-spun composite yarn, because the polyester filaments move periodically and the wool fiber strands move left and right, the yarn has obvious abnormalities in appearance. Symmetrical, graduated variable wrap core wrapping effect, see figure 2 The 11B segment yarn. The composite spinning with periodic and alternating wrapping and wrapping has a high rate of yarn formation, which means that there is very l...

Abstract

The invention relates to a double-shafting fiber interactive equal feeding composite spinning device, technology and application. The device comprises an equal feeding mechanism, a conversion mechanism, and a fiber strand shifting mechanism. The technology for the composite spinning is that endless tows or yarns are a shafting, circumambulate through an upper guide wire and obtain the equal feeding or a trace amount of the equal feeding through a holding roller pair, after that, the endless tows or yarns are randomly or periodically conversed around or move slowly to feed at a jaw of a former top roller through a lower guide wire controlled by a conversion cylinder, and after leaving the jaw of the former top roller, the endless tows or yarns and short fiber strands are gathered to form a double-shafting conversion equal feeding wrapping and core-spun composite spinning under the twisting action, wherein the short fiber strands of another shafting can move around per se. The method is unique and can be implemented easily; and the corresponding device is concise and convenient to install, which can be used for a synchronous conversion equal feeding wrapping and core-spun composite spinning of double-shafting fiber of a ring throstle.

Description

technical field [0001] The invention relates to an iso-feed wrapping composite spinning device for synchronous displacement of biaxial fibers in the field of ring spinning and a composite spinning process using the device. Background technique [0002] Wrapped yarn fabrics have better appearance, feel and comfort, so this kind of fabrics are more popular in the market. Because the fancy effect of wrapped yarn depends on the equal feeding of filament bundles or yarns, traditional wrapped yarns are all under-fed, that is, the filament bundles are under tension. Moreover, the fluctuation of filament tension in composite spinning will seriously affect the structure, quality and appearance of the yarn, especially in low-tension or even no-tension equal-feed output. Therefore, reducing the fluctuation of filament tension in a simple way has always been for Difficulties in this spinning system. Obviously, the key technology of spinning this type of wrapped composite yarn on the t...
