Not all colored fabrics are dyed in the same way. Some are dyed during fabric textile process, some are dyed after weaving, and some are printed only on the surface of the fabric, usually in several different colors. Due to the application of modern technology during the dyeing process, the performance of color has also been greatly improved, but there are also some negligence.

Description Label

The Federal Commerce Commission (FTC) requires manufacturers to attach a permanent description label to textile clothing, which can provide information on the maintenance of textile clothing. The "Descriptive Label Regulations" provides guidance for customers, businessmen and laundry merchants in clothing maintenance. If the label indicates that the word "dry cleaning &rdquo", it means that the clothes can only be washed with dry cleaning solvent. If the words "wash" are marked on it, then the clothes can only be washed.

One of the most effective ways for manufacturers to determine the maintenance process is testing, but this is not always a — a method that works, sometimes both dry cleaning and water washing will have an impact on the clothes.

Generally speaking, you have the right to take the right to keep white clothes properly, because white clothes will remain white for the years it can be worn, while the color of colorful clothes will become darker or brighter.

The best way to keep your clothes quite colored:

1. Read the instructions frequently and maintain your clothes according to the above method.

2. Try to avoid white or colorful clothes from getting in touch with strong light.

3. Follow the bleaching method on the label.

4. If you have any questions about washing clothes, consult a professional laundry person.

Color fading during dry cleaning: Dyes that are soluble in dry cleaning solvents will be severely faded during dry cleaning. If two or more dyes are used together and only one is easily soluble in the solvent, you will see some changes in the color. For example: the yellow part on green clothes made of blue and yellow dyes may be dissolved, and the remaining one is blue, and dry cleaning will also affect various parts of the clothes to varying degrees. For example, a — piece of clothing dyed blue may change back to its previous color, while a blue-white print may fade, so that the blue is no longer suitable.

Fading usually occurs on home clothing, such as bed sheets, etc. Usually the fading of these clothes is not very obvious, and they will not be noticed to fade until compared with other clothes.

Water-washing dye: When clothes are washed, sweating, raining, or encountering water, some dyes will spread. Since some stains need to be removed with water or water-soluble chemicals, dry cleaning requires waterproof dyes.

The water used during washing will also cause some problems on the fabric, such as artificial fibers. After the clothes are dry, dark water stains or stripes may be left on it. Stains remaining on dry-cleaned fabrics are difficult to remove or repair, so they require repeated washing and use of particularly large amounts of water, which makes the problem even worse.

White Clothing: Many people think that white is not a color, but it does belong to one of the colors, and many fabrics themselves have off-white or yellow colors. White fabrics can be treated with fluorescent whitening agents, which can make the clothes whiter.

There are some whitening agents that are instable and may reduce the whitening effect if exposed to strong light. For example, if the front of the sweater is dried directly in the sun, it will easily turn yellow, while the back will still be white, because the whitening agent is very sensitive to light.
