How to distinguish the quality of a pair of jeans fabric?
If it is only distinguished from some accessories such as buttons and leather cards, it is actually quite lacking. These are not highly technical things, there are a lot of people who can make them, so the key is to identify them from fabrics and washing water.
The process of washing water is simple to talk about, but it is difficult to do. Because of space, Xiao E briefly introduces the basic washing effect:
Cat whisker
Use sandpaper to wipe out traces on the trousers. Then spray with potassium permanganate (commonly known as: monkey), then put it in an industrial washing machine, and dry it out. This is just an introduction to the process, and the specific effect will be different due to the difference in the required effect and other reasons, which will cause the process and the temperature of the washing, whether to foam resin, etc. will be different.
Hand rub
Use sandpaper to wipe out a large or small area on the pants surface. Then spray it with potassium permanganate, put it in an industrial washing machine, and then dry it. Wiping by hand is a meticulous job, it looks simple, but it requires experience and skills. In particular, it needs to cooperate with potassium permanganate. A good pair of jeans is evenly and unevenly wiped by hand, which is naturally unnatural. It really tests the skill of the hand wiper. Whether the edge of the hand rub is heavy or light, and the potassium permanganate spray is light or heavy, even and uneven, which will affect the effect of the whole pair of pants.
Crumpled
Crumpled is the wrinkled part we usually see. To achieve this effect, you must first soak the pants in resin, then use a high-pressure steam iron to press out the wrinkles, and then put them in a high-temperature oven to form. The soaking of resin is also more complicated. The soaking time is short, the effect is difficult to come out, and it is easy to fade after washing a few times; the soaking time is long, the fabric will be more brittle, and it can be torn by hand. It is usually judged whether the resin is soaked well or not by tearing the trouser legs or crushing the place.
Tie flowers
Tie flowers are actually the irregular white lines on the pants we see, which look like lightning. This effect is to fold up the trouser legs with high elastic rubber bands (there are also many substitutes), and then put them in an industrial washing machine to wash. After washing it several times, the exposed part will turn white, and there will be irregular white lines.
Whiten
Many jeans that look white or light-colored, the original color of the fabric is not white or light-colored, it is the effect after artificial processing. To make the overall pants into this light-colored effect, you need to wipe the entire pants with sandpaper or a special tool, and then spray potassium permanganate. After washing out, it becomes a light-colored effect. If you open the back pocket or some more hidden place, you can see the original color of the pants fabric, because there is no rubbing and spraying monkeys.
Grind
Some strips are worn out with some small electric tools. Others are worn out. The simple ones are cut with a knife. Cutting and grinding is also very skillful. Some of them are made with tools, so I won’t introduce them too much here.
The above six kinds of washing effects are more common, and most of the washing water comes from handwork. Because some jeans have many washing effects and various types, at this stage, there is no machine that can completely replace artificial machines. Therefore, apart from the price factor of the fabric, the washing effect can also reflect the value of a pair of jeans.
