Stain removal method should be based on the characteristics of stains and flexible use of different stains using different chemicals, the different nature of the stain, the stain removal methods used are also different. The use of well-law, to go stains can help. Otherwise, the light effect of decontamination efficiency, weight loss fabric fibers. Usually remove the stains have the following methods:
First, the jet method
The spray gun is equipped with spray, pure steam, steam, compressed air and other functions, it provides a mechanical force. The spray method is the use of this force, so that the water-based fabric on the stain removal (or partial removal). Application of this method should be noted when the stain:
(A) whether the fabric structure to withstand a certain mechanical force.
(B) whether the stain will not be able to withstand a certain degree of curing or dissolution of the depth of the fabric.
(C) the role of the gun distance and angle, and the jet time.
Second, wipe method
Wiping is the usual way to remove stains. Is to point to the stain on the fabric application of a certain mechanical force, so that the role of the wipe as the stain, from the fabric. Wiping usually has the following forms:
(A) brush
After adding a stain remover to the surface of the stain, tap the surface of the stain with a brush, loosen it, and then lightly brush until the stains leave the fabric.
(B) scraper wipe type
After the surface of the stained agent added to the stain, let it penetrate, dissolve, scraper to scrape stains, so that from the fabric fibers.
(C) positive wipe type
With a thin cloth wrapped in cotton ball formation, dipped in the scouring agent, in the stain surface and its range gently wipe test to remove stains.
(D) back wipe type
With a thin cloth wrapped in cotton balls to form, dip to get scouring agent, gently wipe the stain on the back of the test, so that stain removal.
Third, soaking method
Some stains and fabrics with a close, drip and remove the stains and wipe test can not be successfully removed, you can put the vessel with the stain removers, the fabric of the stain part of the soaking, so that scouring agent can have sufficient time Reacts with the stain. After a suitable period of time, and then brush the light brush to help stains from.
Fourth, the absorption method
For some fabrics, such as fine fabrics, loose fabric structure, or some bleaching serious pollution stains. Such as large-area ball-point pen paint, can be used to help remove the stain absorption. The method is the stain on the fabric by adding the right amount of stain remover, to be dissolved, with a cotton duster on the back of the light suction, the dissolved stains gradually transferred to the cotton group. In each light suction should be replaced after a clean cotton cloth group, to avoid secondary pollution.
Fifth, strong wash method
For large areas of stains, with a mild mechanical effect can not get a good decontamination effect, you can use strong wash method. Apply a scouring agent to the surface of the fabric stains, until it penetrates, brush or brush with a strong force to scratch, through strong mechanical action, so that stains from the fabric.
The use of strong washing method must follow a premise that the structure of the fabric should be brushed tight, wear-resistant, if the color fabric, but also depends on whether the strong color fastness wash. In this way to deal with the stains on the fabric, more or less will produce some damage to the fabric, reducing fabric life. Therefore, not a last resort, do not use strong washing method to stain.
