Will the new clothes fade?

    Some time ago, because of Taobao Double Eleven activities, many small partners took this opportunity to buy a lot of winter clothes to prepare for the winter. In the next few days, everyone's clothes will continue to arrive. Generally, new clothes must be washed before they are put on, but there are many clothes. After washing, they will fade. It is even possible that two different clothes are mixed and washed, and one of them will fade, which will cause the other to dye. Faced with this situation, many people's first reaction is that the quality of clothes is too watery, and it is really the quality of clothes that will fade. Is there any other reason that will cause the color to fade? With these two questions, my little friend looks down!

Why do clothes fade?

Some clothes are faded due to fabric quality problems, but some clothes are not faded for this reason. It may be related to the material of clothes. Natural fibers, such as cotton, hemp, silk and wool, are easy to fade, but artificial fibers, such chemical fibers, will not fade, mainly because they use different dyes. Natural fibers belong to water-soluble anionic dyes, while most artificial fibers belong to water-insoluble disperse dyes and will not fade. Incorrect washing will also affect whether clothes fade.

Color fastness of clothing fabrics will also determine the color fading problem. Color fastness is generally divided into four degrees: washing fastness, rubbing fastness, light fastness and perspiration fastness. However, clothing fabrics generally require high washing fastness. If this degree is low, the color fading of clothes after washing will be serious, which will affect brand sales and image problems. Frictional fastness is the frictional force that can be borne by drying clothes with towels or the like. Light fastness depends on what changes and influences your clothes will have under the sun. Generally, black clothes will not be affected, while white clothes are easy to turn yellow under long-term illumination. Sweat fastness is a question of whether the fabric will fade or not after you sweat. If these degrees are low, it means that your clothes will fade easily even if they are of good quality.

How to wash clothes so that they don't fade?

Now that we know the principle of why clothes fade, what can be done to prevent the back of clothes from fading continuously?

1. Use neutral detergent. Warm clothes such as red and yellow are not dyed firmly, so your friends should pay attention to whether the detergent you use contains bleach. If it does, even black clothes will fade after being washed several times. Therefore, in order to keep clothes from fading, it is best to choose neutral detergent to wash in cold water instead of washing with washing powder, soap or soaking in hot water.

2. Don't wash clothes of different shades. This common sense must be known to most friends. Black and white clothes should be washed separately to avoid color contamination. When washing, you can add a spoonful of salt to it, and remember that the water temperature should be moderate.

 

3. Do not expose clothes to the sun for a long time, especially white and light-colored clothes. This is mentioned above, because the fastness of white clothes is not as high as that of black clothes, and it is easy to turn yellow slowly.

 

4. Pay attention to the washing marks on clothes when cleaning. Every piece of clothing has different cleaning methods. If the cleaning method of a small partner is wrong, it will also damage the fabric of the clothes and affect the fading.

Everyone should remember these little methods when washing clothes! After all, if the newly bought clothes are dyed with other colors due to carelessness, they will not only be difficult to remove, but will eventually become thrown away. What a pity!
