Abstract

The invention relates to a darkening and coloring finishing agent of dyed cotton fabrics and a preparation method thereof. The darkening and coloring finishing agent of the dyed cotton fabrics is prepared by mixing an organic polysiloxane emulsion and methyl hydrogen-contained silicone oil shown in structural formulas in a ratio of 100 to 5-10, wherein R1=-CH2CH2CH2NH2 and / or -CH2CH2CH2NHCH2CH2NH2 and / or -CH2CH2CH2NHCH2CH2NHCH2CH2NH2, R3=-OH and / or -CH3, X=4-6000, Y=1-100 and Z=1-100. The invention has favorable darkening and coloring effects on the dyed cotton fabrics; and the treated dyed cotton fabrics have soft and smooth hand feeling and good washability without remaining substances harmful to human bodies.

Description

technical field The invention relates to a finishing agent for textiles, in particular to a finishing agent for darkening and brightening dyed cotton fabrics and a preparation method thereof. Background technique With the continuous development of textile technology, people have higher and higher requirements for clothing fabrics. One of them is the first sensory evaluation of textiles, that is, color evaluation. Upscale, this effect cannot be achieved only by dyeing, it needs to be finished to improve the depth and vividness of the fabric. The deepening of textile finishing is to cover the fiber surface with low-refractive-index substances, so that the reflectivity of incident light on the fabric is reduced, so that people can visually feel the color of the fabric as "deep". According to the literature, polyurethane, polyacrylate, polyorganosiloxane, etc. are all substances with low refractive index, which have different deepening effects on fibers. Among them, the polyor...
