Production method of conductive blended yarn

Abstract

The invention provides a production method of a conductive blended yarn. The production method comprises the following steps: a, three rows of rollers are arranged into a first drafting region between front and middle rollers and a second drafting region between middle and rear rollers, and the two drafting regions are different in drafting rate; b, an elastic fiber and a complex fiber are suspended on the bobbin hanger of a three-roller spinning frame used in the step a, respectively, next, the complex fiber is continuously fed by the middle roller of the spinning frame, and overfeeding and the drawing of the first drawing region are performed by virtue of the change of the speed of the middle roller so that a complex fiber strand in a sudden changing bamboo joint style can be formed; meanwhile, the elastic fiber is continuously fed by the rear roller of the spinning frame, and overfeeding and the sequential drawing of the second drawing region and the first drawing region are performed by virtue of the change of the speed of the rear roller so that an elastic fiber strand also in the sudden changing bamboo joint style can be formed; c, the complex fiber strand and the elastic fiber strand obtained in the step b are combined and twisted simultaneously by the front roller to form the blended yarn in the special style.

Description

technical field [0001] The invention relates to the field of clothing fabrics, in particular to a method for making conductive mixed yarns. Background technique [0002] In recent years, the petrochemical industry, polymer chemical industry, electronics industry, precision machinery industry, biochemical industry, etc. have grown rapidly and become a trend that countries are chasing. With the development of clothing and wearable devices, more and more electrical equipment and communication equipment will be integrated into people's daily clothing. Thereby, developing a kind of yarn and clothing fabric with conductive properties is a kind of project with great market and social benefits. [0003] For now, the existing clothing fabrics do not have a solution that can perfectly implant conductive fibers. If only conductive materials are mechanically added to the fabric during the weaving process to eliminate There are quite a few options for electrostatic effects. For exampl...
