Abstract

The invention discloses a neutral dye composition which consists of a dye component and an auxiliary component. In the dye composition, three dyes are mixed in compatibility, and each of the three dyes is asymmetric 1:2 metal complex. The composition has better isochromatic property in dyeing wool, chinlon and chinlon-spandex blend fiber to obtain better color tone, better wet fastness, water logging fastness of level 5, rubbing fastness of level 5, light fastness of level 6, perspiration (alkali) of level 4-5, perspiration (acid) of level 4-5, consistent dyeing curve, high dyeing rate and good isochromatic property; and the composition can be widely applied to the dip dyeing for continuous dyeing.

Description

technical field [0001] The invention belongs to the technical field of chemical dyes, and in particular relates to a neutral dye composition. Background technique [0002] Nylon dyeing usually uses acid dyes. When nylon and spandex blended fabrics are dyed with acid dyes, the same color and fastness are poor, and the required shade and quality indicators cannot be obtained, and the chromatogram is incomplete. For this reason, how to have the dyestuff that can adapt to blended fiber dyeing, can have various shades and have better wet fastness is the problem to be solved by the present invention. Contents of the invention [0003] The purpose of the present invention is to provide a neutral dye composition, which solves the problem of poor color homochromaticity and poor fastness when nylon and spandex blended fabrics are dyed with acid dyes in the prior art, and cannot obtain the required shade and quality index, and incomplete chromatogram. question. [0004] In order t...
