Why do clothes fade? 5. Why do clothes fade?

Clothes will fade, there are 2 possibilities, 1 color fastness is not enough, the temperature of the things that come out of the dyeing workshop is not high enough, so it will fade, 2 This dress is dyed garment, that is, the color of the original dress is white, and then after it is made into clothes, it is dyed into other colors, in this garment industry, this is called garment dyeing, but the dyeing process is not good enough, so it will fade.

1. Clothes that are easy to fade are generally made of natural fibers, such as cotton, linen, silk, and wool. Chemical fibers such as polyester (polyester), nylon (polyamide, nylon), spandex (lycra), and acrylic are not easy to fade. This is mainly due to the fact that the properties of the dyes they are suitable for are completely different, and natural fibers are all water-soluble anionic dyes.

Most of the chemical fibers are non-water-soluble disperse dyes.

2. Some clothes are easy to be dyed by faded clothes, and the same reason as above, it is easy to dye those natural fiber fabrics, because they can be dyed with the same dyes (direct dyes, reactive dyes, etc.); The clothes of chemical fiber, because they are mainly dyed with disperse dyes, and because the macromolecular structure of chemical fiber is compact, they must be dyed under high temperature and high pressure, and they will not be stained at all at room temperature, and of course they will not be dyed by faded clothes.

Washing clothes will definitely reduce the dyeing, and when kneading or machine washing, pay attention to the time and strength to avoid fading as much as possible.

You can soak your clothes in salted water overnight so that they don't fade.

Clever anti-fading clothes:

1. The strip cloth or standard cloth dyed with direct dyes has poor adhesion of the general color, and it is best to add a little salt to the water when washing, and soak the clothes in the solution for 10-15 minutes before washing, which can prevent or reduce fading.

2. The blue cloth dyed with sulfide fuel generally has strong adhesion in general color, but poor wear resistance. Therefore, it is best to soak in detergent for 15 minutes, gently scrub with your hands, and then rinse with water. Do not rub with a washboard, lest the cloth turn white.

3. The green cloth dyed with oxidized fuel is generally dyed relatively firm and shiny, but it is easy to turn green when it encounters reducing gases such as gas. So, don't bake your washed green cloth clothes by the stove.

4. Although the fastness of dyeing is relatively good, the color is generally attached to the surface of cotton yarn. Therefore, wearing this kind of colored cloth should prevent friction and avoid the white of the cotton yarn from being exposed, resulting in serious fading and whitening.

That.

First, the proportion of animal fibers in the fabric fibers of today's clothing market has increased, and the coloring process of all these natural fibers and dyes is a physical process, and its light fastness, washing fastness, and friction fastness are not very good;

That. Second, there are some small dyeing factories or individual dyeing factories in the garment market that only want to benefit but do not pay attention to quality, and the technical requirements and standards are far from the international standards, so the quality of fabric dyeing problems are piled up;

That. 3. Now in the national detergent war, each manufacturer first emphasizes the high strength of washing and decontamination performance, and the decontamination rate is proportional to the decontamination rate, and the result is that the color of the clothes is removed at the same time as the decontamination. While the clothes became cleaner, the color also became old.

That. Fourth, if the laundry is washed with organic detergent, and some dyes on the clothes are easily soluble in the organic liquid, so every time you wash the clothes, part of the dyes on the clothes will be dissolved, which is why some clothes are less and less bright after washing.

Cotton clothes and knitwear in bright colors such as red or purple. The way to do this is to add some ordinary vinegar to the water in which you wash the clothes for a while before washing them! But the amount of vinegar should not be too much, otherwise it is easy to dye light-colored clothes.

If you can wash your clothes like this often, you can ensure that the color of your clothes is as clean as new!

The second trick to prevent color dropping: flower water cleaning method.

Ingredients required: Toilet water.

The second trick is more suitable for cotton fabrics and woolen fabrics, the method is to wash the clothes according to the conventional method, after the clothes are rinsed, drop a few drops of toilet water in clean water, and then soak the washed clothes in such water for ten minutes. Clothes washed in this way can also be disinfected, sterilized and sweat odor removed.

1. The reason for the discoloration of the clothes may be because of the material itself. Clothes that are easy to fade are generally made of natural fibers, such as cotton, linen, silk, and wool. Chemical fibers such as polyester, nylon, spandex, and acrylic are not easy to fade.

2. The reason for the discoloration of the clothes may also be due to the fact that the treatment of the clothes is not in place after dyeing. Clothing dyeAfter the clothes are dyed, some clothes dyes penetrate into the inside of the clothing fibers, and some have not had time to penetrate into the fibers, but only attach to the surface of the fibers.

3. Solution: It is recommended to choose good quality clothes to buy in the process of choosing clothes. At the same time, in the process of washing clothes, it is necessary to pay attention to the laundry according to the advice provided by the sales staff, and do not cause the dye on the clothes to decolor because the water temperature is too high when washing the clothes.

If you wash your clothes for the first time according to the regular procedure, don't panic, if it is a cotton fabric or nylon fabric, you can buy a small bottle of cotton fixing agent or acid fixing agent at home for color fixing.
