Different fiber fabrics, different dirt, removal methods are also different, must pay attention to the operation method and the characteristics of the fabric used, such as waterproof rolling backpack, otherwise it may cause certain damage to the product fabric.Therefore, be very careful when actually cleaning and pay attention to the following aspects:
Reasonable selection of fabric characteristics and decontamination materials
Because wool fabric is protein fiber fabric, the dye with acid as the medium is mainly used in the dyeing process, therefore, alkaline decontamination material should be avoided, because alkali can destroy protein (wool fabric), make the fabric damaged, and to a certain extent destroy acid media, produce local fading, thus producing color difference.Cotton fabrics are usually dyed with alkaline materials, so the use of acidic materials may cause discoloration of the fabric, and soda or soap should be used for reduction. Additional, general brunet fabric, because need undertakes protecting to color, such as a red laptop smart backpack it is advisable to try sample first when using decontamination material so.
Choose the right decontamination method
Generally speaking, the washing decontamination method of besmirch divides water to wash and dry clean two kinds of types, when specific choice should decide according to the characteristic of fabrics and the kind of besmirch.For textile fabrics, if there is no special design or technical requirements, can be used to wash, but in the state of semi-finished products, it may not be convenient to wash, need to use dry cleaning method.Thousand wash decontamination tools have toothbrush, glass plate, mat cloth, cover cloth, etc.The gasket must be a clean white, wetted cotton cloth, folded into 8~ 10 layers and placed flat on the glass plate.
When decontamination, put the decontamination board below the fabric that has besmear first, besmear USES decontamination material next, reenter toothbrush dips in water perpendicular direction to knock gently, or heat makes dirt and decontamination material fall off gradually to hot mat cloth go up.Some stains often have to be removed many times, the use of pads must be washed often to keep clean.If the use of chemical dry cleaning, operation from the edge of the stain to the center of wipe, prevent the spread of stains to the outside, at the same time, force can not be too large, to avoid fabric wool, cause visual defects.
Attach importance to decontamination after treatment to prevent the formation of residual traces
After decontamination, the fabric is easy to form obvious edges due to local contact with water, if not treated in time, it is very easy to leave a yellow ring mark.No matter what kind of decontamination material is used, after the removal of stains, should be immediately dipped in water with a toothbrush to the fabric with water brush some larger area, and then spray around some water, so that it gradually desalination, in order to eliminate its obvious edge profile.
