Dye for printed cloth

Abstract

The invention discloses a dye for printed cloth, and relates to the technical field of fine chemical engineering. The dye for the printed cloth is prepared from the following components in parts by weight: 20-30 parts of nitro and nitroso dyes, 5-8 parts of polymethine dyes, 2-8 parts of sodium chloride, 3-6 parts of disodium hydrogen phosphate, 8-12 parts of sodium dihydrogen phosphate, 4-6 partsof sodium thiosulfate, 2-6 parts of sodium carbonate and 8-10 parts of urea. The dye for the printed cloth is good in coloring and is not liable to lose color and fade.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a dye for calico. Background technique [0002] Textile dyes are usually formulated by artificial proportioning according to needs, but the products obtained after printing cloth with existing textile dyes have poor colorability and insufficient color fastness. It is prone to fading and fading after use. Contents of the invention [0003] The purpose of the present invention is to provide a kind of dyestuff for calico, and it is good in coloring, and is difficult to lose color, fade for above problem. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a dye for calico, which is composed of the following composition ratios: 20-30 parts of nitro and nitroso dyes, 5-8 parts of polymethine dyes, chlorinated 2-8 parts of sodium, 3-6 parts of disodium hydrogen phosphate, 8-12 parts of sodium dihydrogen phosphate, 4-6 pa...
