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
What the present invention relates to is the after-finishing of textile products agent, and what be specifically related to is that a kind of dyed cotton fabric increases and increases gorgeous finishing agent and preparation method deeply.
Background technology
Continuous development along with textile technology, people are also more and more higher to the requirement of garment material, one of them is exactly to be the evaluation of color to the evaluation on textiles first sense organ, people wish that the color of colored fabric is more bright-coloured, bright, tone is more superior, this effect is inaccessible by dyeing only, need promote the fabric degree of depth and vividness by the back arrangement.It is to utilize the low-refraction material to be covered in fiber surface deeply that after-finishing of textile products increases, and the reflectivity of incident light on fabric is reduced, and make people visually produce the sensation of " deeply " to the color of fabric.Introduce polyurethane according to document, polyacrylate, polysiloxane etc. all are the materials with low-refraction, and fiber is had the different dark effects that increases.Wherein the refractive index of polysiloxane is lower, and the fabric after its arrangement is increasing and also has softness, smooth hand feeling concurrently in dark.
Prior art CN200810163784.4 patent disclosure a kind of amido silicon oil with N-(β-aminoethyl)-Y-aminopropyl methyl dimethoxysilane modification make the fabric brightening agent, its result of use is remarkable to dark polyster fibre, and for cotton, the polyester-cotton blend of dyeing, wash fabric effect and not obvious such as sticking, wool.
Prior art CN 200810060886.3 patent disclosures a kind of vinyl monomer of using, hydroxy silicon oil and response type function monomer etc. adopt the deep-dyeing agent of emulsion polymerization technique preparation.Since the initator N hydroxymethyl acrylamide that uses in synthetic can be on fabric residual harmful formaldehyde, and the fabric feeling after this deep-dyeing agent is handled harden, coarse, thereby influence the popularization and the use of product.
Summary of the invention
The increasing of dyed cotton fabric that be used for of a kind of function admirable that the purpose of this invention is to provide increases gorgeous finishing agent deeply, and it is made up of organic siloxane emulsion and a certain proportion of Methyl Hydrogen Polysiloxane Fluid emulsion of multiple functional group modification.This finishing agent has dyed cotton fabric and well increases dark and brightening effect, and it is smooth to handle the back fabrics feel soft, and washability is good, not residual insalubrious material.
