Spinning technology

1. Carding

Sliver

Carding machine belongs to textile machinery. According to spinning process, carding is an important process. The first process of carding machine is opening and cleaning combined machine, and the second process is drawing frame.

Carding machine is used to process cotton fiber and chemical fiber.

The working principle of the carding machine is to open, comb and remove the cotton (fiber) roll sent from the previous process or the oil cotton (chemical fiber) layer supplied by the cotton box. It is the function that all the cotton rings in the form of curly and quick shape become the basic single fiber. In this process, the broken seeds, impurities and short fibers left from the cleaning process are removed, and then the cotton strips of certain specifications are integrated and stored in the cotton drum for drawing Process use.

2. Twisting

The twister is a textile machine that twists many threads into one. Its function is to process yarn or composite yarn products into linear products for weaving and knitting. The utility model comprises a twisting machine body and a circuit part, wherein the spindle outside the twisting machine body is connected with the motor output shaft of the circuit part, and the spindle front end is provided with a connecting piece corresponding to the tap changer.

The twisting machine is suitable for twisting and laminating of cotton, cotton, chemical fiber, embroidery thread, nylon, polyester, rayon, sewing thread, silk, glass fiber, etc.

Feeding mode of twisting machine: flat tube feeding pure twisting frame or cone tube feeding and twisting frame, parallel tube or pagoda yarn (wood tube or paper tube) feeding and pure twisting frame.

The earliest twisting tool: the spinning wheel unearthed at Banpo site in Xi'an, Shaanxi Province in 1955 is the earliest twisting tool invented in ancient China, that is, inserting a rod into the hole in the middle of the spinning wheel, using the rotation of the spinning wheel to screw the fibers together, and using the same method to synthesize a single strand of fibers into a more solid "thread".
