1. A simple and easy way to keep colorful clothes bright after washing is to use detergent with fluorescent brightener. Because the fluorescent brightener contained in this detergent is actually a fluorescent dye which is dissolved in water; It will be absorbed by the fiber of the clothes, and will not be washed off immediately, and can turn the ultraviolet part of the light invisible to the naked eye into visible light.

Generally, the visible wavelength is 400-800 angstroms, while the ultraviolet wavelength is 300-400 angstroms. When the fluorescent dye absorbs ultraviolet light, it can be converted into violet, blue and blue light with a wavelength of 400~500 angstroms.

Therefore, after washing clothes with detergent containing such substances, the whiteness of the laundry can be increased. Because fluorescent brightener can increase the whiteness and brightness of the laundry, even clothes of different colors will be more brilliant after washing because of the complementary effect of ultraviolet light to visible light.

2. Shirt washing

Before washing the shirt, first coat the collar on the whole inverted part of the collar, brush it with water with a toothbrush, remove the stain, and then put it into the washing machine and wash with detergent. This method can also be used if the cuff is dirty. After the next pass of water, do not dehydrate, take out the wet shirt directly, use both hands to push the sleeves and collar of the clothes straight, fold the clothes according to the reverse crease of the original collar from the two ends of the neckline to the whole section of the reverse fold position, straighten the collar tip to make the collar shape symmetrical, hang the wet shirt with a coat hanger, and then dry the water. This can reduce the wrinkles on the shirt body, ensure that the collar is not blistered and the collar tip is not warped, and keep the collar clean and straight.

3. Washing of wool and woolen clothes

Before washing, dust should be removed, and then soaked in cold water for 15 to 20 minutes. After taking out and squeezing, neutral detergent solution, detergent solution or alkaline detergent solution (such as soapy water solution) should be selected, and the solution with strong detergency, soft feel, good luster and easy to rinse after washing should be put into it to gently scrub to prevent damage to the clothes, and then washed with clean water.

In order to maintain the brightness of the color, 2% acid vinegar or vinegar can be dropped into the water to neutralize the residual soap. After washing, squeeze out the water, put it into a net pocket, hang it in a ventilated place to dry, take it out when it is 80% dry, and then lay it flat on the table and hang it before drying.

In fact, in order to prevent the wool from being twisted, curled and deformed or damaged, the wool and sweater pants should be put into a gauze bag for weak washing. The washing time should not be too long and the water temperature should not be too hot. When drying, in order to prevent the clothes from falling, you can spread them on the table to dry them naturally, or you can fold the woolen clothes and pants and put them in a clean net bag to dry.

4. Washing of silk clothes

Silk clothing is characterized by its softness and smoothness. It is easy to float and sink in the washing liquid. It is twisted by the wave wheel at the bottom of the washing cylinder, which affects the normal rotation of the wave wheel, and may be damaged in serious cases.

Therefore, silk clothes should be washed in a slightly wide gauze bag. In order to make the washed silk clothes shiny and bright, you can drop a small amount of vinegar into the washing solution. When washing, it is advisable to use lukewarm water and "weak washing", and the washing time should not be too long.

5. Some fabrics will wrinkle if they are only washed and dried, and the wrinkles can be removed by ironing them. Some fiber clothes are made of non-ironing materials, which will not have obvious wrinkles even if they are not ironed.
