How cotton is woven into cloth (1)

Tigers have seen a little of the world except that they can't fly well. What do you see? Funnily enough, the tiger finally saw the whole process of cotton weaving into cloth. Hehe, it has the same effect as grandma Liu entering the Grand View Garden. The object of tiger research is a cotton mill, which is small in scale, but the sparrow is small and complete. Lao Sun, the factory director, is a cool person. You can tell at a glance that he is an expert who has been rolling around in the factory all his life. Tiger and Lao Sun talked a lot about the factory, and then Lao Sun warmly invited Tiger and his colleagues to visit the production workshop. Half out of curiosity and half out of work, the tiger agreed at once. The tiger followed me into the workshop from a lifted curtain. I feel that the light is much darker and there is no one in the workshop. What you see is rows of cotton bales, which are discharged very neatly. Lao Sun said that this is the material preparation workshop, and the prepared cotton is unloaded. Because of the quality difference of natural cotton, in order to ensure the quality stability of the spun cloth, technicians should combine different batches, different producing areas and different colors of cotton according to a certain proportion before production. This series of prepared cotton is the result of their work. Old Sun said as he pushed open a small door at the end of the workshop to let the tiger in first. The tiger immediately fell into the roar of the machine. This is completely different from the previous seminar. There are unknown large machines and workers walking around everywhere. It's bright and noisy here. I enthusiastically introduced myself to the tiger, but this time he had to put his mouth to the tiger's ear and shout loudly. It turns out that this is a cotton washing and carding workshop. After the newly prepared row of cotton is moved here, it will be put into a cotton washer and carding machine and stirred evenly to remove impurities and short fibers. The cotton washer is huge, and its lower part is a big iron plate. Workers take apart a row of raw cotton and put it in this big iron plate. The mechanical arm inside will stir the cotton as well as possible. A square sucker is hung on the iron plate, and a long tube is attached behind the sucker, extending from the roof to the end of the workshop. This suction port keeps rotating along the iron plate, sucking cotton in little by little. The sucked cotton dances along the pipeline above the workshop under the action of the blower and reaches the outlet of the pipeline. When cotton is transported in the pipeline, heavier impurities will settle down and slide down from the small riser supporting the pipeline to the debris tank. This process is equivalent to washing one side of raw cotton, so it is called cotton washing. The washed cotton is collected in the drum at the pipe outlet of the cotton washer, and the drum keeps rotating during the cotton loading process, so that the packed cotton wadding is naturally rolled into a cylindrical shape. Whenever a barrel is full of cotton, the workers move the barrel and send it to the next process.
