Denim clothing has been loved by more and more people. Its personality is changeable, it is versatile, and the longer it wears, the more distinctive it is. The main reason is that denim fabric is different. Compared with all other fabrics, it seems that there is a certain This kind of magic, and this magic comes from its complicated production process. There are thousands of people in the denim industry. The people who have seen all the production processes are few and far between. Some of them can be called For a certain master of a certain work, it is admired.
A seemingly simple denim is not so simple. From the beginning of the raw material cotton to the final formation of the grey fabric, at least to the top ten processes, these ten processes are called the process of denim fabric production.Â Although many people are unheard of, let alone understand, but understand the principle, in fact, can be summarized in ten words, namely, “clear, comb, and, thick, fine, complex, whole, pulp, wear, weave “.Â The meaning of each word is briefly introduced as follows.
First of all, the first five words are called “clear, comb, and thick, fine”. This belongs to the spinning part. Generally, the first four characters are collectively referred to as the front spinning, that is, the four major processes before the yarn is formed.Â The rules are post-spinning.Â â€œClearâ€ is to open the cotton, mix and match different grades, different fiber lengths, different origins or different components of cotton or other fibers according to a certain ratio, and then use machinery to open, beat, tear and other actions to remove impurities. , cottonseed, seed cotton, infertile seeds, sand and other foreign matter, and then evenly rolled into, so that it can enter the next process.
The comb is combed, that is, the comb-shaped cotton loop which has been mixed in the open cleaning process is used for carding and combing to form a single-fiber sliver.Â And the draw is, that is, the combed sliver is again removed by the draw frame, and then dispersed into about two or three fingers thick sliver.
The coarse or roving process, which is similar to the drawstring, splits the sliver into a sliver of about a small finger.Â These four process textile mills are generally referred to as the pre-spinning process.Â Then enter the post-spinning process: the spun yarn and the winding.Â The fine spun yarn is spun into a roving sliver made of a roving process into a yarn of a desired size, such as 16S, 12S, 10S, 7S, and the like.
After these five processes, they enter another five processes, which are also the five-character essence, called “complex, whole, pulp, wear, weave.”Â The winding is the winding, which is to re-process the yarn in the spinning process and wrap it around the paper tube or wooden tube, so that it can be used in the next process. If it is used as the weft yarn, it can be packaged into the warehouse after the winding process, and then enter the market for circulation. If it is used as a warp yarn, it will enter the next process, that is, “whole”. The warping is to wind thousands of yarns dyed with the desired sizing through a warping machine to wind a good package of yarn into a kind of warp beam. Bearings, we must know that a piece of denim fabric is intertwined with at least several thousand cotton yarns, and the warp yarns are dispersed into a warp beam consisting of more than ten yarns composed of several hundred yarns.
