Embodiment 1

[0025] According to the above method, the roving is cotton fiber, the diameter of the water outlet of the dripping device is 4mm, and the distance from the center of the water outlet to the front jaw is 6cm. Yarns with a linear density of 30tex and a twist coefficient of 330 were spun by liquid film spinning, and then the hairiness index was tested with a YG173A hairiness tester. The specific results are shown in Table 1.

Embodiment 2

[0027] According to the above method, the roving is ramie fiber, the diameter of the water outlet of the dripping device is 1 mm, and the distance from the center of the water outlet to the front jaw is 10 cm. A spun yarn with a linear density of 30tex and a twist coefficient of 330 was spun by liquid film spinning, and then the hairiness index was tested with a YG173A hairiness tester. The specific results are shown in Table 1.

Embodiment 3

[0029] According to the above method, the roving is wool fiber, the diameter of the water outlet of the dripping device is 8mm, and the distance from the center of the water outlet to the front jaw is 2cm. Yarns with a linear density of 20tex and a twist coefficient of 315 were spun by liquid film spinning, and then the hairiness index was tested with a YG173A hairiness tester. The specific results are shown in Table 1.

Abstract

The invention relates to a spinning method, in particular to a liquid film spinning method, and belongs to the technical field of spinning. According to the liquid film spinning method, in the process of ring spinning, a water dripping device is added and installed between a guide wire and a front jaw formed by a front roller and a front skin stick of a ring spinning frame, and the yarn is fed through the water dripping device between the front jaw and the guide wire. The yarn penetrates through water droplets attached to the end of the water dripping device, hairiness fibers stretching out of backbones of the yarn hang out a liquid film wrapping the yarn from the water droplets, the hairiness fibers on the surface of the yarn attach to the backbones of the yarns through the contraction effect of the liquid film surface tension and involve in a twisting process of backbone fibers, the hairiness fibers on the surface of the yarns have the opportunity to be rolled into the backbones of the yarns to achieve the effect of reducing yarn hairiness. The liquid film spinning method has the advantages of no energy consumption, no noise and easy maintenance of the device.

Description

technical field [0001] The invention relates to a spinning method, in particular to a liquid film spinning method. It belongs to the field of textile technology. Background technique [0002] The fiber varieties used in traditional ring spinning have wide adaptability, simple equipment principle and convenient operation. However, more hairiness will be formed when spinning by this spinning method. During the spinning process, the front nip formed by the front roller and the front top roller continuously outputs flat roving strands made of fibers, and the fibers are parallel to the axis of the strands. The twist generated by the rotation of the traveler is transmitted to the front jaw through the yarn guide hook, so that the strands at the front jaws rotate around their own axis, the width of the strands gradually narrows, and the two sides are gradually folded and drawn into the center of the yarn, forming Twisted Triangle. In the twisting triangle, the width and cross-s...
