Why do jeans fade?

Question 1: Why do jeans fade? Is it a material problem? Landlord, this question is really a good one. . . It really took me a lot of effort.

I have a little opinion, but not necessarily right, just for discussion.

Cotton-padded jacket, like tee, generally uses combed cotton or slender cotton, and uses high count yarn for shirts. The higher the count, the finer the cotton fiber. When dyeing, the fiber is soaked in dye, and then some processing techniques are adopted to make the dyeing firm and dry, which generally requires multiple dyeing. The finer the fiber, the easier it is for natural dyes to penetrate into the fiber and make it fully dyed. Therefore, the color fading in cotton-padded jacket is not constant, but subtle, and the better the quality, the less the color fading.

Denim is denim, which is denim. The diameter of the cotton fiber used is much larger, and the impurity content is high, so it is difficult for the dye to be completely immersed in the fiber, and the impurities in it will make the fixation effect of the dye worse. In the high-end products of Japanese cattle, there is also a natural dyeing. They use natural dyes, which are extracted from natural plants. Among them, natural dyes are not as pure as chemical dyes, so it is difficult to color. Therefore, general chemical dyeing needs about 10 times, while natural dyeing needs 24 times. Natural substances contain ingredients that make them difficult to fade, and there are many colors, so natural dyeing will be much more difficult to fade than chemical dyes that can be bought in general. However, due to various restrictions such as cost, it is impossible for ordinary brands to use natural dyes.

That's about it. I hope to help the landlord.

Try washing your pants with laundry detergent.

Usually when washing jeans at home, they are all washed with laundry detergent. Try not to wash with washing powder. Washing powder will aggravate the color fading of clothes. After long-term use, the color of jeans will become lighter and lighter, losing its original color.

Question 7: How do pure jeans fade? Jeans are basically irreversible if they are mixed and dyed. If you soak it in disinfectant or washing liquid again, I'm afraid the dye of jeans will fall off faster. If you want pants to have a better solid color, you can soak them in salt water when you just wash them, which will wash off the surface color, especially the dark pants. It won't fade after washing. Soaking jeans in salt water several times can't prevent them from fading. A better way is to put a proper amount of white vinegar in jeans every time to fix the color. In fact, if you want to keep a pair of jeans, you should wash them as little as possible and blow dry them after each wear. Many people wash jeans once every six months.
