Fabrication process of conductivity type doubling and twisting yarns

Abstract

The invention discloses a fabrication process of conductivity type doubling and twisting yarns. The process comprises the following steps: a, a first drafting zone between a front roller and a middle roller and a second drafting zone between the middle roller and a rear roller among three rows of rollers are formed, wherein the drafting multiples of the first drafting zone and the second drafting zone are different; b, conductive fiber, elastic fiber and positioning adjusting fiber are respectively hung on a suspended spindle of a three-roller spinning frame in the step a, and the conductive fiber and the positioning adjusting fiber are simultaneously and persistently fed from the middle roller of the spinning machine; through speed change of the middle roller, overfeeding and drafting of the first drafting zone are performed, so that first fiber strands with choppy bamboo joint style are formed; at the same time, the elastic filer is continuously fed from the rear roller of the spinning machine, through speed change of the rear roller, overfeeding is performed, and through the drafting of the first drafting zone and the second drafting zone, second fiber strands with gradient bamboo joint style are formed; c, the first fiber strands and the second fiber strands in the step b are combined simultaneously through the front roller and are then twisted to form doubling and twisting yarns with a special style.

Description

technical field [0001] The invention relates to the field of clothing fabrics, and more specifically, to a manufacturing process of conductive double-twisted yarn. 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 electrosta...
