When the new semester arrives, students will wear new uniforms. How should parents clean school uniforms to ensure their health?
School uniform washing and maintenance knowledge
Generally speaking, because uniforms are used in conventional fabrics, the following points should be noted during washing and maintenance:
1) Cotton knitwear, the normal shrinkage rate after washing is ≥6%, the pants are polyester-cotton knitwear, and the normal shrinkage after washing is ≥3%.
2) The national standard for clothing size deviation is ≥5%. If two sets of the same uniforms are purchased, but the size is different, it does not mean that the uniform is unqualified, so you can use it with confidence.
3) School uniforms should be cleaned after purchase. The school uniforms of dark and light colors should be washed separately to avoid mutual dyeing. Do not wash the colored school uniform with bleaching powder, do not soak it in bleach, or wash it with hot water above 30 °C.
4) Cotton school uniforms are easy to wrinkle and deform, so do not wring them out after cleaning. When they are half dry, they should be pulled by hand in the key parts such as collar and front squat. The school uniforms will be flat and the children will be more rejuvenated.
Teach you four tricks to help you prevent uniforms from cleaning
The dark school uniform will usually have floating color for the first time. It is mainly the dye that is not fixed after the dyeing of the fabric. This is all the clothes are unavoidable, as long as it is not large or very serious. It is a quality issue. This kind of floating color is generally as long as the washing method is correct, and it will not be washed a few times. The fading is not serious and the washing method has a great relationship. Most of the dyes of colored clothing are easily dissolved in water; in the wet state, the dye is also easy to fade under the action of sunlight; the dye and fiber lines are not firmly combined, and will fade when washed. Therefore, in order to prevent the fabric from fading, please pay attention not to soak in hot water, soapy water or alkaline water for a long time during washing. Do not use a washing board or a brush to brush.
The first trick to prevent fading: pickling. Need raw materials: vinegar
This move is mainly for bright cotton uniforms 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 clothes. If you can clean the school uniform this way, you can ensure that the color of the school uniform is as clean as new!
The second measure of anti-fading: toilet water cleaning method. Need raw materials: toilet water
The second measure is more suitable for cotton uniforms. The method is to clean the uniform according to the conventional method. After rinsing, add a few drops of toilet water in the clean water, and then soak the cleaned school uniform in such water for ten minutes. School uniforms cleaned in this way can also be used for disinfection and sweat removal.
The third measure to prevent fading: salt water immersion method. Need raw materials: salt
This is the best way to deal with the fading problem of the suit. In order to prevent fading, the newly purchased school uniforms can be soaked in concentrated brine for half an hour before being first launched, and then washed according to conventional methods. If there is still a slight discoloration, you can soak it in light salt water for 10 minutes before each water cleaning. If you persist in the past, the school uniform will never fade again!
The fourth trick to prevent fading: anti-sun method.
This method is most commonly used, especially for some dark school uniforms. The method is very simple, that is, the school uniform is turned back to the air. Here you should be especially reminded that most fabrics are not directly exposed to the sun, because ultraviolet light is the main culprit in the fading of clothes. Therefore, not only should you dry the air in the opposite direction, if possible, put the clothes in a place where it is protected from light and ventilation.
