Production device and dyeing technology of feather yarn

Abstract

The invention relates to a production device and a dyeing technology of feather yarn. When yarn of a drawing frame is broken, the yarn can touch a detecting ring, a sensor transmits a signal to give out an alarm, a motor is controlled to be stopped, a worker finds out the yarn breaking position and conducts knotting, a roving frame can automatically suck the broken yarn to a nearby automatic knotting device for knotting operation, the yarn broken head can be automatically found out, the knotting operation can be quickly conducted, the operation efficiency is high, the knotting quality is high,and the quality of yarn products can be guaranteed. Through a yarn guide and twisting mechanism of a spinning frame, a long groove is formed in a leather roller, a core thread vertically penetrates through the long groove, steering of the core thread is avoided, hairiness at the periphery of the core thread and misplacement are avoided, and the yarn after stranding is guaranteed. When dyeing is conducted in a dyeing cylinder, the dyeing technology is improved, dark stirring water in the dyeing cylinder can be removed completely, the dyeing effect of the yarn is guaranteed, and the quality ofthe yarn products is improved.

Description

technical field [0001] The invention relates to a feather yarn production device and a dyeing process thereof, belonging to the technical field of textile machinery. Background technique [0002] Feather yarn needs to go through wool blending, wool blending, carding, drawing, roving processing, spun yarn processing, dyeing and other processes in the production process. [0003] The drawing frame is to use the drawing frame to feed the yarn in the feeding barrel through the feeding device, and then the yarn is easy to break during the feeding process, resulting in too little yarn feeding, which cannot meet the production requirements. resulting in defective products. [0004] During roving processing, the roving frame winds the roving into a certain package through drafting and twisting to meet the processing requirements of the spinning frame. However, when the roving frame is winding the yarn, it is easy to produce yarn breakage at the pressure frame. In the past, after t...

AI Technical Summary

Problems solved by technology

However, when the roving frame is winding the yarn, it is easy to produce yarn breakage at the pressure frame. In the past, after the yarn breakage, it was necessary to manually find out the broken end of the yarn, and then manually tie the knot. However, it is not only inefficient to find out the broken end of the yarn. High, and prone to omissions, and yarn knotting is a cumbersome work. Manual operation is not only inefficient, but also the quality of knotting is uneven, and the quality of yarn products cannot be guaranteed.

[0005] The yarn guiding and twisting mechanism of the roving frame adopts double-layer yarn guiding tubes for horizontal conveying of the core thread and thread pressing. However, after the horizontal yarn guiding tube feeds the core thread, it needs to turn vertically downwards and send it to the yarn drum, but in this way Turning will cause hairiness around the core wire and affect the straightness of the core wire, which will easily cause misalignment and reduce the quality of the yarn product

[0006] When dyeing, when the conventional dyeing process dyes the dark yarn, the dark stirring water in the dyeing vat cannot be cleaned, resulting in poor yarn dyeing effect and affecting the quality of the finished yarn.
