Analysis of Color Fastness of Textiles

 With the development of society and technological progress, the color of textiles more and more. Walking in the street, a variety of colors of the dazzling array of clothes. Of course, there are many experts are worried about people's clothing consumption concept, people used to wear clothes because of the need, and now people wear clothes more just for consumption. Every year people will buy a lot of clothes hoarding in their own closet, spend more time every day to think of their dress, people wear clothes from the original monochrome to the present colorful, this reflects the progress of society, But we still have to restrain, although the living conditions are good, we can not forget that hard years, we all know that now colorful clothes in the cleaning time sometimes change, dark clothes will wash more light, will be different Color clothes shuffling is easy to lead to a color transfer to another color, this article is to explain the color of the textile will happen how the so-called textile color fastness is how the same thing.
Dyes: usually colored organic compounds, mostly soluble in water or through a certain chemical treatment, into a water-soluble substances, they can be fiber material with physical, chemical or physical and chemical combination of dye on the fiber , And the dyeing does not have a certain color fastness. Also some pigments need to be adhered to the surface of the fabric or garment by coloring it with the aid of a polymeric binder. There are many kinds of dyes for cellulose fiber dyeing are mainly direct dyes, reactive dyes, vat dyes, sulfur dyes, insoluble azo dyes; for protein fiber dyeing acid dyes, acid mordant dye; for chemical fiber Dyeing with disperse dyes for polyester dyeing, cationic dyes for dyeing acrylic fibers, and the like. The composition of the pigment consists of three categories, namely: inorganic pigments, organic pigments after grinding fine powder, fluorescent pigments.
Friction color fastness: When the friction between the fabric, one of the dark fabric due to more pigments, will be transferred to another dry fabric in the friction, the general situation occurs in dry and humid environment Dark fabric and light-colored fabric friction. Example: If you put a red t-shirt on your clothes, white underwear and white underwear will turn pink. You have gone through the fabric decolorization (dye touches the water, unlocks the shirt and moves to the underwear from the red dye in the water). If you are wearing red t-shirts and white pants. You take off your coat and pants on the red stains, inform them to come in contact with your shirt, you experienced the fabric friction (two cloth rubbed together, causing the problem). From the dye on the surface of the dyed or printed fabric to another surface. The friction strength determines the amount of fuel transferred. The decolorization of this dye is the result of mechanical wear such as friction and wear. In the process of fabric production, lack of dye penetration, improper dye and dyeing procedures will make the fabric in the friction when the serious dye transfer, textile dyeing or printing process through the friction and color fastness can be intuitive to show. Technically, this friction decolorization can occur in dry or humid conditions.
