A damp heat twist fixing system

Abstract

The invention discloses a damp and hot set twisting system. The system comprises a hollow channel, wherein a gap is formed at one end of the hollow channel, the other end of the hollow channel is connected with a support which is formed by a material with a good heat conduction function, a heating device with set temperature is assembled on the support, and the heat which is generated by the device can be transferred to the hollow channel through the heat conduction support; and holes are respectively formed on the sides of the two ends of the hollow channel, and the hollow channel is connected with a gas delivery pipeline through the holes. According to the damp and hot set twisting system, the closed hollow channel is adopted, and an up-down structure wet gas inlet and outlet mode is combined, so that the utilization rate of wet gas flow can be effectively increased; harmful yarn hair can be greatly reduced, and yarn surfaces are smooth; the single-yarn strength can be effectively increased; the yarn internal stress balance can be realized effectively, the residual torque in yarn bodies is reduced, and the subsequent weaving and processing are benefited; and the system is very important to increase resultant yarn comprehensive quality and product additional value.

Description

technical field [0001] The invention relates to the new technology field of ring spinning, in particular to a damp heat twist fixing system which can be installed on a ring spinning frame to reduce yarn hairiness, improve yarn strength and reduce yarn residual torque. Background technique [0002] Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. The difference in length, elongation and stress, in the process of twisting and forming yarn, the fibers are transferred radially inward and outward, and wrapped repeatedly. On the one hand, the head and tail ends of the side fibers are not easy to be wrapped into the yarn sliver to form hairiness; at the same time, the side fibers and the center fiber are under different tensions and will not break at the same time when stretched, so the strength of each single fiber cannot be fully util...
