Low-temperature circulating air flow device for worsted production

Abstract

The invention provides a low-temperature circulating air flow device for worsted production. The low-temperature circulating air flow device includes a yarn steaming box, a moving assembly and a circulating air flow device. The yarn steaming box is a half-sealed internal pressure thin-wall container. The left end of the yarn steaming box is embedded in a seal cover, the seal cover is provided withthe moving assembly, and the circulating air flow device includes an infrared heating pipe, a suction fan and an air feeder. The left end of the yarn steaming box is fixedly connected with the inletend of the suction fan, the top of the right end of the yarn steaming box is fixedly connected with the outlet end of the air feeder, the outlet end of the suction fan is fixedly connected with an airguide pipe, and a three-way pipe is fixedly mounted at the left end of the air guide pipe and fixedly connected with the yarn steaming box and the inlet end of a fan. Through the circulating air flowdevice, the air speed in the yarn steaming box is uniform, the generation of a heating blind area is avoided, the yarn twist is balanced, yarn quality is improved, the yarn color is durable, the production efficiency is greatly improved while claims for compensation caused by yarn skew are reduced, manpower resources are saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wool spinning production, in particular to a low-temperature circulating air flow device for worsted spinning production. Background technique [0002] Different from other fibers, wool fiber has excellent curling performance. During the production process, it is elongated by carding and drawing, which makes the fiber have a large internal stress. If the stress generated by the fiber during the production process cannot be eliminated in time, it will cause weaving. The difficulty of production increases, and some physical indicators and appearance styles of the product are difficult to stabilize, which cannot meet the design requirements of the product. The traditional method is to increase or extend the storage period in the production process. The general production period is 3 to 6 months. Although this is of great benefit to ensure product quality and appearance style, the longer production period obv...

AI Technical Summary

Problems solved by technology

Domestic steamed yarn generally adopts wet heat setting and dry heat setting, but the traditional steaming method and steaming equipment have certain disadvantages. After steaming, the performance of the yarn is reduced, and the final garment is not soft and comfortable enough.

Foreign countries generally use electric steaming boxes with a high degree of automation. Although the temperature, time and humidity in the steaming box can be set arbitrarily, and the whole process of yarn humidity and heat setting can be automatically controlled, the disadvantage is that the wind speed in the steaming box is not uniform. It is easy to cause unbalanced yarn local twist and uneven yarn strength
