Spinning method capable of adaptively regulating yarn structure and false twisting device

Abstract

The invention relates to a spinning method capable of adaptively regulating and controlling a yarn structure and a false twisting device, and belongs to the technical field of spinning processing. An electromechanical device is mainly adopted to drive a rotating device to run at a high speed, and a tension device regulates a contact behavior and restrains yarn movement by means of self weight; during spinning, yarns pass through a gap between the rotating device and the tension device; and the transverse friction force generated by high-speed rotation of the rotating device regulates and controls the fiber arrangement structure and heats the yarn at the same time, so that the fiber modulus is reduced, and the fibers are fully transferred. The false twisting device is simple and reasonable in structure and high in production efficiency, and the spun yarn has the advantages that the hand feeling is soft, the strength is improved, hairiness is obviously reduced, and the evenness is stable.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a spinning method and a false twist device for self-adaptive regulation and control of yarn structure. Background technique [0002] The spinning process is an important link in the entire spinning process. The quality of the yarn produced in this link directly affects the subsequent weaving efficiency and the quality of the finished product. The yarn obtained by the traditional ring spinning technology is currently the most important yarn production technology because of its high strength, uniform yarn dryness and good hand feeling. However, an important defect of traditional ring-spun yarn is that with the twisting effect, the residual torque of the obtained spun yarn is relatively large, which seriously affects the performance of the final fabric, and the application of false twisting device can obtain low-torque ring-spun single yarn, It has obvious effect on real...

Chinese Patent Publication No. CN110616480A, publication date 2019.12.27, the name of the invention is a false twist compact spinning device with a rotary disc structure. The false twist device with a disc rotary structure provided by this patent is located on the output side of the front roller. The feeding side of the take-out roller, and the false twist device has a yarn guide, and the yarn guide is arranged on the front side, or rear side, or the spinning channel where the fiber strands on both sides of the false twist point pass through, although The yarn guide has a limitation on the space of the spinning channel, which can suppress the divergence of fibers at the edge of the fiber whiskers, but it will cause additional friction and collision between the fiber whiskers and the yarn guide during the spinning process, resulting in yarn dryness deterioration

A rotating disc is used to form two twisting points to perform false twisting on the spinning section output by the front roller, and the separator bar is installed between the two false twisting points to make the fiber bundles and the upper edge and lower edge of the spinning false twisting disc The edges are tightly combined to separate the two false twist points and increase the pressure between the spinning section and the disc. Although this invention can reduce the size of the spinning triangle and increase the yarn sliver in the spinning triangle Twist, so as to increase the strength of the fiber bundles in the twisting triangle area of ​​spinning, but the addition of spacer rods, the spatial position between the spacer rods and the original spinning section, and the depth parameters of the spinning section pressed down by the spacer rods are not easy to control. It will lead to uneven pressure between the spinning section and the disc, increased spinning tension, and prone to end breaks

[0003] The above-mentioned false twisting devices only work on yarn torque balance, and none of them can significantly reduce hairiness
