Yarn of cellulose types - an important influence on the quality of the ribbon

Ribbon color fastness is important audit index of textile printing and dyeing, textile and use different kinds of dye the color fastness of the audit index is endless and same, because the different kinds of dyes, color fastness audit index difference of up to a half. Wash fastness of dyed cotton webbing (white color) vat dye 4-5, and sulfide, naphthol, reactive dye is 3 level. This is due to the various Ribbon dye molecular structure, chemical properties, such as the difference of difference also textiles joint method, joint cooperation is not identical, some ribbon dye is and the textile fiber molecules produce chemical reaction and chemical bond method to joint in the textile, and some dyes so physical reaction method fixed in the textile.

According to the classification process for important ribbon, woven belt and knitted with two major categories. Ribbon, especially jacquard ribbon, and cloth standard process is similar, but cloth standard firm warp and weft expression pattern; and ribbon fundamental weft is strong, by the warp expression pattern, used in small dull, each version, the production of wear yarn and mediation stiff probably have a spend very long, and obey relative is not high. But can produce many kinds of products, giddy, not like those standard cloth that always look.

The ribbon is decorative function, also has the efficacy of the. Such as the prevalence of mobile phone sling, etc.. Woven tape out later, can also a variety of screen printing ink / pattern, as is usually lower than the ink pattern woven out will be cheaper. High strength polyester ribbon receiving material, with high strength, high temperature resistance, high strength, flame resistance etc.. Also can be the credential anti sweat on the ribbon surface sticking a layer of PVC, through special process for PVC and ribbon fully bonded together to wear resistance, corrosion resistance, anti sweat, elegant results.

Therefore, the color fastness of the audit indicators are not identical. Therefore, it is very important to determine the type of dyes on the printing and dyeing fabrics to audit its color fastness. Ribbon according to the principle of dyeing and finishing, to deal with different textile materials, also differences in acceptance of the kinds of dyes, identity credentials of textiles can be start infer kinds of dyes used, and held for trial held verification.
