Conductive Cotton Yarn for Knitting

Conductive cotton yarn

Conductive fibers include two types of filaments and short fibers. The use methods and scope of the two are different, and each has advantages and disadvantages. Conductive filaments are often formed into strips or lattices on the fabric by inlaying. More staple fibers are added to the fabric by blending. Considering the antistatic mechanism of textiles containing organic conductive fibers, filaments are prone to form charge escape paths. Experiments show that in order to achieve the same antistatic performance, the amount of short fibers added is about 10-20 times that of filaments. In addition, when organic conductive filaments are applied to knitted fabrics, the added amount required is higher than when applied to woven fabrics.

 1) Conductive component exposed type: The conductive component is distributed and exposed to the fiber surface, the discharge is very fast, and the antistatic effect is good. Although this form of fiber has a good antistatic effect, it will cause the conductive particles to be lost due to washing and friction to reduce the conductive performance.

 2) Three layers of concentric circles: This is a composite fiber that sandwiches conductive components in the middle layer. Non-conductive components and conductive components are between 80: 20 ~ 60: 40. If the non-conductive component is too large, the conductivity decreases, and if it is too small, the spinnability deteriorates. This sandwich structure makes the conductive component both close to the surface and wrapped in the middle, so the whiteness increases and is resistant to washing and rubbing, and the conductive effect is good and has durability.

 3) Side-by-side type: This is to divide the fiber into two, three or more layers in parallel, so that the conductive component penetrates the fiber cross section and is exposed at both ends, so the charge can be conducted to the other side of the fiber, making it perpendicular to the fiber axis The conductive effect increases. The conductive part of this fiber is not easy to exceed 30%, so as not to reduce the fiber's conductive durability, friction resistance and washing resistance, and can increase the conductivity by increasing the number of parallel layers.

The production method of cotton yarn is relatively complicated. Generally speaking, there are currently two methods of spinning, namely carded spinning and combed spinning.

(1) Carding spinning process: cotton blending → opening and clearing → carding → drawing → roving → spun yarn → dropping (two types of manual winding and automatic winding) → finished product inspection.

(2) Combing spinning process: cotton blending → opening and clearing cotton → carding → drawing → sliver winding → combing → drawing → roving → spun yarn → doffing (two types of manual winding and automatic winding) → Product testing.

Cotton yarn is widely used, it can be used as weaving yarn, such as: bed sheets, quilts, curtains and other home textile series. It can also be used as knitting yarn, especially combed yarn can be used to produce high-quality textiles, such as high-grade undershirts, fine poplin, etc. Cotton yarn can also be used to produce electrical yellow wax cloth for special industries, tire cords, and high-speed sewing threads. And embroidery thread.
