Technical Post: Principles and common methods for removing stains on textile fabrics.
Fabric will be stained with stains during use. Some stains cannot be removed by conventional washing or dry cleaning methods. In this case, you should choose the appropriate Detergents or chemicals for spot removal.
1. Principles of stain removal
According to different fiber materials and different stains, different stain removers are used to remove stains.
(1) It is possible to remove stains in time
After the fabric is stained with stains, it must be removed in time. If the time is too long, the stains will penetrate into the fiber and be firmly bonded to the fiber, and even chemical reactions will occur, making it impossible to remove.
(2) Different measures should be taken for different types of stains
For the same stain on different fabrics, different stain removers and methods are used. Use appropriate stain removal methods and detergents based on the nature of the stain and the type of fabric.
(3) Different measures are taken for different types of fabrics
Some stain removers can damage some fibers or color. You need to understand the fiber composition of the fabric before choosing the appropriate stain remover and method.
(4) The movements should be relaxed and avoid violent brushing
When removing stains, be gentle and wipe from the outside to the center to spread the stain.
2. General methods for stain removal
Different fabrics require different stain removal methods. At present, the main methods for stain removal are spraying, soaking, wiping and absorbing.
(1) Spray method
A method of removing water-soluble stains using the spray force of a spray gun. Suitable for fabrics with tight structure and strong bearing capacity.
(2) Soaking method
Use chemicals or stain removers to allow sufficient reaction time for the stains on the fabric to remove the stains. Suitable for fabrics where stains are closely bonded to the fabric and the stain area is large.
(3) Wiping method
Use a brush or a clean white cloth to wipe the stain to remove it. Suitable for fabrics with shallow stain penetration or stains that are easier to remove.
(4) Learning method
Inject the stain remover into the stain on the fabric, wait for it to dissolve, and then use cotton to absorb the removed stain. Suitable for fabrics with fine texture, loose structure and easy to discolor.
3. Issues that should be paid attention to when removing stains
(1) Pay attention to safety
Gasoline, alcohol, turpentine, etc. are flammable. Keep away from fire when using and storing them. Pay attention to poison prevention when using oxalic acid, and seal the organic detergent after use to prevent evaporation.
(2) Pay attention to the nature and usage of detergent
Strong acid will carbonize cotton, linen, viscose fiber and other fabrics. Pay attention to the concentration, temperature and time. Silk and wool fiber fabrics do not need ammonia or alkaline water to remove stains. If necessary, the concentration must be low and the operation must be fast. When using organic solvents to remove stains from chemical fiber fabrics, be sure to prevent the fabric from melting and causing damage. Colored and printed fabrics should prevent fading and color matching.
