Method for removing different kinds of stains on curtain fabric

I. Principles of stain removal
    According to different fiber materials and different stains, different stain removers are used to remove stains.
   (A) Remove stains as soon as possible
    The stains on the fabric should be removed in time. If the time is too long, the stains will penetrate into the fiber and be firmly combined with the fiber, and even a chemical reaction will occur, so that it cannot be removed.
   (Two) different measures for different types of stains
    Different stains and methods are used for the same stain on different fabrics. According to the nature of the stain and the type of fabric, choose an appropriate decontamination method and detergent.
   (Three) different measures for different types of fabrics
    Some detergents are detrimental to some fibers or color. You need to understand the fiber composition of the fabric first, and then choose the appropriate stain remover and method.
   (4) Be brisk and avoid strenuous brushing
    When decontaminating, move lightly and wipe from the periphery to the center of the stain to prevent the stain from spreading.
Second, the general method of stain removal
   Different fabrics should use different decontamination methods. At present, the main methods for removing stains are spraying, soaking, wiping and absorbing.
  (1) Spray method
   A method for removing water-soluble stains by using the spraying force of a spray gun. Suitable for fabrics with tight structure and strong bearing capacity.
  (Two) soaking method
   The use of chemicals or detergents and stains on the fabric have a sufficient reaction time to achieve the method of removing stains. It is suitable for fabrics with tightly combined stains and fabrics and large stain areas.
  (Three) wipe method
   Wipe the stain with a brush or a clean white cloth to remove the stain. Suitable for fabrics with lighter stains or easier stain removal.
  (4) Absorption method
   A method of injecting a stain remover into a stain on a fabric, allowing it to dissolve, and then absorbing the removed stain with cotton. It is suitable for fabrics with fine texture, loose structure and easy discoloration.
3. Issues to note when removing stains
  (A) pay attention to safety
   Gasoline, alcohol, turpentine, etc. are flammable. Keep away from fire when using and storing. Oxalic acid should pay attention to anti-toxic, organic detergent should be sealed after use to prevent volatilization.
  (Two) pay attention to the nature and use of detergents
    Strong acid will carbonize fabrics such as cotton, linen, and viscose fiber. Pay attention to the concentration, temperature, and time. Silk and wool fiber fabrics do not need ammonia or alkaline water to remove stains. When necessary, the concentration must be low and the operation must be fast. When removing stains on chemical fiber fabrics with organic solvents, prevent the fabric from dissolving and causing damage. Dyed and printed fabrics should prevent fading and color matching.
    How to remove common stains
    Oil stains: wipe with a clean cloth or soft-bristled brush dipped in gasoline, then wash with warm water
    Ink: For new ink stains, rub the rice grains on the stains, rub them with detergent, and rinse with water. Old ink stains are repeatedly rubbed with a 1: 2 mixture of alcohol and soap, and then rinsed with water
    Blue ink stains: New stains are immediately immersed in cold water and can be removed by rubbing with soap. Old stains are dipped in 2% oxalic acid solution, then washed with detergent, and finally washed with water
    Red ink stains: New stains are soaked in cold water to remove floating colors, and then soaked in washing solution for about 15 minutes. Old stains are washed with detergent first, then rubbed with 10% alcohol solution or with potassium permanganate solution
    Ballpoint pen oil: After soaking in cold water, wipe with benzene or carbon tetrachloride, or soak in cold water, apply toothpaste and rub with a small amount of soap, then remove with alcohol
    Shoe polish: Wipe with gasoline, turpentine, or alcohol, then wash with washing liquid
    Sweat stains: Soak the stains in concentrated brine for about 15 minutes, then rub them with detergent
    Juice stains: New stains can be removed by rubbing with saline. Old stains can be wiped with 20 times diluted ammonia and rubbed with detergent
    Blood stains: Do not wash with hot water to avoid preheating and coagulation, which is difficult to remove. After soaking in cold water for 15min, rub the stained area with enzyme detergent and rinse with water
    Wine stains: New stains can be washed with water. Old stains are rubbed and washed with a mixture of 2% ammonia and borax water, and then rinsed with water
    Soy sauce: Soak new stains in cold water, then wash with soap or detergent. Old stains can be washed with 2% ammonia in detergent and rinsed with fresh water
    Oil stains on leather shoes: wipe with gasoline or alcohol, then wash with soap and rinse with water
    Crayon or carbon paper stains: Wipe the stain with alcohol, scrub with warm detergent, and rinse with water
    Mildew stains: The newly generated mildew stains are washed with a brush and warm water, then wiped with alcohol, and then rinsed. Old mold stains are immersed in dilute ammonia for several minutes, then treated with potassium permanganate solution, and finally washed with sodium bisulfite solution.
    Rust: Scrub with 1% oxalic acid solution, then rinse with water
