Overview of composite fabric information

Cotton processing is the process of processing seed cotton into lint. The process of separating the fibers from the cotton seeds is called ginning.
The development of cotton processing machinery has promoted the development of cotton planting and cotton spinning industries, while the substantial increase in cotton production has promoted the development of cotton processing industry.
The earliest cotton gin used in the world was a very simple wooden roller winch. It used two wooden rollers parallel to each other, mounted on two wooden pillars on the left and right, and the handle of the lower active wooden roller was moved by hand. The wooden roller rotates, and a driven wooden roller above relies on friction to rotate along with it. Put the cotton into the gap between the two rollers, the cotton fibers will be pulled out by the relative rotation of the upper and lower rollers, and the cotton will be prevented from being separated from the cotton fibers. This type of winch first appeared in India and was called “Chukka”. At the end of the Song Dynasty and the beginning of the Yuan Dynasty, Huang Daopo, a famous textile technology innovator in my country, created an iron-wood roller winch car based on the wooden roller winch car, and replaced the driven wooden roller with an iron roller. One end of the iron roller The wooden bar is worn horizontally, and when the iron roller rotates, the wooden bar can act as a flywheel. When twisting flowers, shake the wooden roller by hand and step on the pedal with your feet to drive the iron roller to rotate, increasing the friction against the wooden roller and greatly improving the production efficiency, as shown in Figure 6-1. In 1840, American MacArthur invented the punch-knife top roller gin, which was the prototype of the modern top roller gin. After continuous improvement, it gradually evolved into the current top roller gin. The sawtooth gin was invented by ElWhitney and Hodgen Holmes between 1792 and 1796.
