Why do some clothes become smaller after washing? Understand the principle of water reduction and the method of remediation at once

Have you also had such experience? When I was about to dry my clothes after washing my clothes, I found that my favorite sweater or shirt was a small size, and the clothes that were originally fit became tight and twisted. Is this caused by a faulty washing water temperature setting?

In fact, the reason for shrinking is not just the simple washing temperature, it involves the material, structuring method, and even the molecular structure of the fiber. Only by understanding the principle behind it can you really avoid the clothes getting smaller and smaller as you wash them, and you can even have the opportunity to rescue them after an accident.

These natural fibers composed of fibers are straightened and arranged during processing. When they absorb water, the molecular chains will expand and lose their arrangement, causing the fiber to retract and shorten, resulting in the overall size shrinking.

In addition, the way of editing also has an impact, such as loose scattering is easier to shrink than tight slim.

2.Wool (animal protein fiber)

Wool is composed of keratin and is covered with a layer of fine tablets. When heated and friction, these tablets will open and confuse each other, forming the so-called exclusive phenomenon, which will permanently reduce the clothing.

However, most modern wool clothing has been treated with anti-shrinkage, which can reduce this situation. Despite this, it is recommended to follow the instructions for washing.

3. Synthetic fibers (such as polyester, nylon)

This type of fiber is made of petroleum-derived polymers, which is more stable in structure and less likely to deform. In addition, synthetic fibers tend to be long-sized structures that do not need to be twisted like cotton or wool, so the shrinkage risk is lower.

Will washing clothes with cold water have any impact?

Although hot water is more likely to expand and release the fiber, cold water and washing mechanical movement can also cause some materials to shrink, especially those of the regenerated fiber.

To reduce water reduction risks, it is recommended to use the following method:

. Wash with cold water

. Select low-speed water repellent or soft wash mode

. Put it flat as much as possible to prevent the clothes from deforming by themselves

. What should I do if my clothes are slimmed with high water risk? These methods can be tried

Although most of the minus water cannot be completely restored, partial size can still be restored to allow the clothing to be worn in a barely manner.

Method 1: Soaking hair cream (use of natural fibers such as cotton and syrup)

1. Add about 1 spoonful of hair cream or baby shampoo per liter of warm water to make it more ductile

2. Soaking water-reducing clothes 10-15 Minutes

3. Lift water, do not dry

4. Put the clothes flat and slowly stretch back to their original size

5. Dry on a flat surface or under light tension (for example, tied to both ends of the hanger)

Method 2: Steaming ironing method (applicable to wool, less severe shrinkage)

1. Turn the clothes over

2. Use the steaming function of the iron to heat the cloth on one side and then gently pull the cloth

3. Keep the tension fixed before the fabric is cooled *If the wool has been expanded, for example, the texture becomes dense and the hair feels gone, the effect of this method is limited.
