How To Clean The Stains On My Bag?

1. Types of stains

Bag stains can be divided into four main categories: hydratable, oil, protein and glue.

(1) hydratable stains

Hydratable stains such as paste, sweat, tea, sugar, soy sauce, cold drinks, fruit juice, ink, ballpoint pen oil, rust, red and blue ink, red and purple potion, iodine, etc. General hydratable stains can be dried with water and wet cloth. Can be hydrated class stains such as red potion, purple potion, iodine, red and blue ink, has its distinctive color; tea stains, water stains are light yellow and have a deeper edge, not hard, which is the difference with protein stains; thin glue stains on the fabric hard, sometimes also have a deeper edge, but when water is easy to soften.

(2) oil stains

Oil stains such as machine oil, food oil, paint, ointment, etc. Oil stains in addition to paint, asphalt, thick machine sleeve, the general edge of the oil stain can gradually fade, and often diamond-shaped ( long in the longitudinal direction and short in the latitudinal direction). This type of stain is generally easier to identify.

(3) protein stains

Protein class such as blood, milk, insects, sputum snot, sores and pus. Protein stains in the fabric generally no fixed shape, but are hard, and have a deeper edge, which in addition to blood stains, insect stains of darker color, most of the rest are light yellow.

(4) glue stains

In the production process of bags, many processes have to use adhesive, a little carelessness will cause product contamination, causing adverse effects on the appearance. Generally speaking, because the solvent in the adhesive are organic solvents, so water can not be removed, adhesive stains need to use raw rubber blocks and organic solvents to remove, so in the production process should try to pay attention to cleanliness and hygiene.

2. Common stain removal methods

Different stains have different physicochemical properties, generally according to the solubility of the stain to dissolve, and then remove the principle to deal with. Bag products common stains and their removal methods are as follows:

(1) fruit juice

First of all, use salt water or 5% ammonia in the dirt scrubbing, after a few minutes to dissolve the dirt can be cleaned and removed. If the peach juice contamination, because the peach meter is rich in high-valent iron ions, so you can first scrub with oxalic acid, and finally wash with detergent can be.

(2) tea stains

Tea stain removal method is relatively simple, with hot water heated to 70 ~ 80 ° C scrubbing, or with a mixture of concentrated salt water, ammonia and glycerin scrubbing, you can wash away the tea stain.

(3) vegetable soup, milk

If it is vegetable soup, milk juice and other pollution with grease nature, generally first use gasoline to dissolve the grease, followed by 1:5 ammonia solution scrubbing, when the stain is removed then rub with soap or detergent, and finally rinse with water.

(4) red ink stains

First scrubbed with 40% detergent red ink stains, and then 20 % alcohol solution or potassium permanganate solution can be removed.

(5) blue ink stains

If it is just dyed blue ink stains, immediately soak the fabric in cold water with soap repeatedly scrubbing, such as there are obvious traces, continue to use 20% oxalic acid solution dip, the temperature is generally controlled at 40 ~ 70C, and then wash with detergent.

(6)Ink stain

The main component of the ink is carbon black and bone gum, generally with rice or batter rubbing, that is, the ink can be dissolved to remove. In addition, you can also use 1 part of alcohol, 2 parts of soap and 2 parts of toothpaste made of paste rubbing, rinse with water.

(7) soy sauce stains

First detergent solution slightly heated to slightly warm, then add 20% ammonia or borax solution scrubbing, and finally rinse.

( 8) ballpoint pen oil stains

First wet the contaminated parts with warm water, then repeatedly wipe with benzene or acetone, and then clean with detergent. Can also be wet with cold water, Xu some toothpaste and a small amount of soap lightly rubbed, such as residue, and then wash away with alcohol dissolution.

(9) paint stains

Paint stains can be used gasoline, turpentine, banana water or benzene scrubbing, and then scrub with soap or detergent.

(10) sweat stains

First soak the contaminated part with 1 %~-2% ammonia, then scrub it in 40~50C warm water, if there are still traces, put it into oxalic acid solution for washing. Silk fabrics should not be washed with ammonia, generally more citric acid washing, so as not to damage the fabric.

( 11) iodine stain

The contaminated parts can be immersed in alcohol or hot water to dissolve the iodine and then wash to remove. Can also be rubbed with starch paste and then washed with clean water.

( 12 ) animal and vegetable oil stains

Animal and vegetable oil stains are generally well soluble in organic solvents, so you can use gasoline, banana water, carbon tetrachloride and other organic solvents to remove. 3.

3. Stain cleaning and finishing considerations

Different fiber fabrics, different stains, different removal methods, must pay attention to the operation method and the characteristics of the type of fabric used, otherwise it may cause some damage to the product fabric. Therefore, we should be very careful when cleaning and pay attention to the following aspects:

(1) the product fabric characteristics and decontamination materials between the reasonable choice

Because the wool fabric is protein fiber fabric, in the dyeing process mainly use acid as the medium of dyes, so avoid using alkaline decontamination materials, because alkali can destroy the protein (wool fabric), so that the fabric damage, and to a certain extent destroy the acid medium, resulting in local fading, thus producing color differences. Cotton fabrics generally use alkaline materials for dyeing medium, so the use of acidic materials may cause discoloration of the fabric, but also use soda ash or soap to restore. In addition, where the dark fabric, because of the need to protect the color, so the use of decontamination materials to first try a small sample as appropriate.

(2) choose the correct stain removal method

Generally speaking, the stain washing and decontamination method is divided into two types of water washing and dry cleaning, the specific choice according to the characteristics of the fabric and the type of chapter stain to determine. For textile fabrics, if there is no special design or process requirements, you can use the water washing method, but if it is in a semi-finished state, it may not be convenient for water washing, you need to use dry cleaning methods. The tools for dry cleaning are toothbrush, glass plate, pad cloth, cover cloth, etc. The cloth must be a clean white, wet and dry cotton cloth, folded into 8~10 layers and placed flat on the glass plate.

Stain removal, first put the stain removal board under the stained fabric, and then coated with stain removal materials, and then toothbrush dipped in water to tap gently in the vertical direction, or heat so that the dirt and stain removal materials gradually fall off to the hot pad cloth. Some stains often have to be repeated several times to remove clean, the pad cloth used must be washed frequently to keep clean. If you use chemical dry cleaning, the operation should be rubbed from the edge of the stain to the center to prevent the stain from spreading outward, while the force should not be too large to avoid fabric pilling, causing visual defects.

For leather or artificial leather fabrics, you only need to wipe with the corresponding chemical reagent to dissolve the stain and remove it.

(3) Pay attention to the post-defilement treatment, to prevent the formation of residual traces

After decontamination, because the fabric local water easily formed obvious edge, such as not timely processing is very easy to leave a yellow circle traces. No matter what kind of decontamination material is used, after removing the stain, should immediately use the toothbrush dipped in water to brush the area of the fabric encountering water, and then spray some water around it, so that it gradually fade, in order to eliminate its obvious edge contour.
