First, the principle of stain removal According to different fiber materials, different stains, using different detergents to remove stains. (a) Remove dirt as soon as possible After the fabric is stained with stains, it must be promptly removed. If the fabric is too long, the stain will penetrate into the fiber and the fiber will bind firmly to the fabric. Even chemical reactions may occur so that it cannot be removed. (b) Different types of stains take different measures The same stains on different fabrics, the choice of detergents and methods vary. According to the nature of the stain and the type of fabric, choose the appropriate decontamination method and detergent. (c) Different kinds of fabrics take different measures Some detergents are detrimental to some fibers or shades. It is necessary to understand the fiber composition of the fabric before selecting the proper decontamination agent and method. (D) Action should be brisk, avoid vigorous hard brush When decontamination, the movement should be light, wipe from the periphery of the stain to the center to prevent the spread of stains. Second, the general method of stain removal Different fabrics should use different decontamination methods. At present, the main methods of stain removal include spraying, soaking, wiping and absorption. (a) Spray method A method of removing water-soluble stains by the action of a spray gun spray force. Suitable for fabrics with tight structure and strong ability to withstand. (b) Immersion method The use of chemicals or detergents and stains on the fabric have sufficient reaction time to remove stains. It is suitable for fabrics with a combination of stains and fabrics and a large stain area. (c) Wipe method Wipe the stain with a brush or a clean, fine cloth to remove the stain. It is suitable for fabrics where the stain penetration is lighter or easier to stain.

It is suitable for fabrics with fine texture, loose structure and easy discoloration. Third, attention should be paid to the removal of stains (a) pay attention to safety Gasoline, alcohol, turpentine, etc. are flammable products. Keep away from fire when using and storing. The oxalic acid should pay attention to anti-virus, and organic detergents should be sealed after use to prevent evaporation. (B) pay attention to the nature of the detergent and use of methods Strong acids will cause carbonization of cotton, hemp, viscose, and other fabrics. Attention should be paid to concentration, temperature, and time. Silk, wool fiber fabrics do not use ammonia or alkaline water stains, if necessary, the concentration must be low, the operation should be fast. When removing stains on chemical fiber fabrics with organic solvents, prevent the fabrics from dissolving and causing breakage. Dyeing and printing fabrics should prevent fading and coloring.
