15 kinds of stain removal, antifouling and self cleaning methods for textile fabrics

First. The principle of stains and removal

According to different fiber materials and different stains, different stains are used to remove stains.

(1) remove stains as soon as possible

Fabric stains must be removed in time. If time is too long, stains will penetrate into the fiber and firmly combine with fibers, even chemical reactions will not be eliminated.

(two) different types of stains are taken to take different measures

The same kind of stains on different fabrics, the selection of removing pollution agents and methods are different. In accordance with the nature of the stain and the variety of the fabric, the proper method of removing pollution and removing pollution agent should be selected.

(three) different kinds of fabrics take different measures

Some anti fouling agents are damaged to some fiber or color. It is necessary to know the fiber composition of the fabric first, and choose the proper cleaning agent and method.

(four) the action should be brisk, and should not be violently brushing

When removing pollution, the movement should be brisk, from the periphery of the stain to the center, so as to prevent the stain from spreading.

Two. The general method of removing stains

Different materials should be used for different methods of removing pollution. At present, the main methods of removing stains are injection, soaking, wiping and absorption.

(1) injection method

The method of removing water soluble stains by the effect of jet gun ejection force. It is suitable for fabric with tight structure and strong bearing capacity.

(two) soaking method

The use of chemicals or detergent and stains on the fabric has a full reaction time to get rid of the stains. It is suitable for the fabric which is tightly combined with the fabric and has a large stain area.

(three) wiping method

Use a brush or clean white cloth and other tools on the way to get rid of stains to wipe the stains. It is suitable for fabric with shallow or easy to remove stains.

(four) absorption method

When the stain is injected into the fabric, it will be dissolved, and then the cotton is used to absorb the stains that are removed. It is suitable for fabric with fine texture, loose structure and easy decolorization.

Three. The problems that should be paid attention to when the stain is removed

(1) pay attention to safety

Gasoline, alcohol, turpentine, etc. are flammable products. They should be kept away from the fire when they are used and stored. Oxalic acid should be paid attention to antivirus, and the organic expelling agent should be sealed after use, in order to prevent volatilization.

(two) pay attention to the properties and use methods of the expelling agent

The acid will make cotton and flax, viscose fiber fabrics such as carbonization, we must pay attention to the concentration, temperature and time. Silk and wool fabrics are not soaked with ammonia or alkaline water. If necessary, the concentration must be low and the operation should be fast. When the organic solvent is used to remove stains on the chemical fiber fabric, it is necessary to prevent the breakage from dissolving the fabric. Dyeing and printing fabrics should prevent color fading and coloring.
