When the new semester comes, students will wear new school uniforms. How should parents clean the school uniforms to ensure the health of their children?
school uniform washing and maintenance knowledge
Generally speaking, as school uniforms are made of conventional fabrics, the following points should be paid attention to when washing and maintaining them:
1) For cotton knitwear, the normal shrinkage after washing is ≥ 6%, and for trousers, the normal shrinkage after washing is ≥ 3%.
2) The national standard for clothing size deviation is ≥ 5%. If you buy two sets of the same school uniforms, but there is a deviation in size, it does not mean that the school uniforms are unqualified. You can use them with confidence.
3) School uniforms should be washed first after purchase, and dark and light uniforms should be washed separately to avoid mutual staining. Colored school uniforms should not be washed with laundry with bleach, soaked in bleach, or washed with hot water above 30 ℃.
4) Cotton school uniforms are easy to wrinkle and deform, so don’t wring them out after cleaning. When they are half dry, you should pull them by hand at the collar, front and other key parts. After they are dry, you can pull them by hand. The school uniforms can be very flat and make children more energetic.
I’ll teach you four tips to help you prevent the discoloration of school uniforms.
Dark school uniforms usually have floating colors when they are first launched, mainly the dyes left after the fabric is dyed, which are unavoidable for all clothes. As long as they are not large-scale or especially serious, they are generally not quality problems. This floating color will disappear after several times of washing as long as the washing method is correct. The severity of fading is closely related to the washing method. Most of the dyes of colored clothes are easy to dissolve in water; In wet state, the dye is also easy to fade under the action of sunlight; The combination of dyes and fiber lines is not strong enough, and they will fade when washed. Therefore, in order to make the clothes not fade, attention should be paid not to soak in hot water, soapy water and alkaline water for a long time when washing, and not to rub with a washing board or brush.
The first way to prevent color fading: pickling. Raw material required: edible vinegar
This move is mainly aimed at pure cotton school uniforms with bright colors such as red or purple. The method is to add some ordinary vinegar to the water for a while before washing the school uniform! The amount of vinegar should not be too much, otherwise it is easy to dye light colored clothes. If you can wash the school uniform like this often, you can ensure that the color of the school uniform is bright and clean as new!
Anti fade second trick: toilet water cleaning method. Raw material required: toilet water
The second move is more suitable for cotton school uniforms. The method is to first clean the school uniforms according to the conventional method, rinse them, drop a few drops of toilet water into the clean water, and then immerse the cleaned school uniforms in such water for ten minutes. The school uniform cleaned in this way can also play the role of disinfection and sterilization and removing sweat smell.
The third way to prevent color fading: saltwater immersion method. Raw material required: salt
This move is most suitable for dealing with the fading problem of school uniforms. In order to prevent fading, the newly bought school uniform can be soaked in concentrated brine for half an hour before being put into the water for the first time, and then cleaned according to the conventional method. If there is still a slight discoloration, you can soak it in light brine for ten minutes before washing it in the water. If you persist in this for a long time, the school uniform will never discolor again!
The fourth trick to prevent color fading: anti sunlight method.
This method is most commonly used, especially for some dark school uniforms. The method is very simple, that is, hang the school uniform upside down. Here is a special reminder for you: most fabrics of clothes can’t be directly irradiated by the sun, because ultraviolet rays are the main culprit of clothes fading. Therefore, it is not only necessary to dry the clothes in the reverse direction, but also try to dry them in a place away from light and ventilation if possible.
