Abstract

The invention discloses a dyeing agent for wig complex fiber containing amino silicon oil. According to the the dyeing agent, reactive dyes are adopted to prepare dye liquor, cationic etherifying starch is utilized to carry out cationization processing on polyving akohol, and the cationic polyving akohol reacts with the reactive dyes to prepare reactive dye liquor which has high adhesive property and dye uniformity, so that a certain retarding effect and protecting effect are achieved, and the dyeing effect of complex fiber is improved; the added amino silicon oil has favorable adsorbability and compatibility, the hand feeling and the mechanical strength of the fiber can be improved after the amino silicon oil is combined with the complex fiber, and the complex fiber is prevented from swelling and becoming brittle during the dyeing process; the wig fiber processed by the dyeing agent prepared by the invention is uniform and fast in color, smooth in hand feeling, and durable in water washing and dry washing.

Description

A kind of wig composite fibre coloring agent containing amido silicon oil and preparation method thereof

Technical field

The present invention relates to wig coloring agent technical field, particularly relate to a kind of wig composite fibre coloring agent containing amido silicon oil and preparation method thereof.

Background technology

Wig is very common in daily life, the material of wig is also varied, wherein apply wider mainly artificial compounded fiber, wherein a class obtains with protein and the blend spinning of the material such as polyacrylonitrile, polyvinyl chloride, it has and really sends out the texture and feel that compare favourably, intensity, toughness and the performance such as fire-retardant are also better, and the market response is better.Because the color of consumer to wig has different demands, the dyeing of wig is an important link in process of production, swelling, sex change, the unequal situation of dyeing is easily there is in conventional coloring agent when processing above-mentioned composite fibre, composite fibre is caused to lose due intensity and toughness, fall flat, and the security of coloring agent itself also has problems.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of wig composite fibre coloring agent containing amido silicon oil and preparation method thereof.

The present invention is achieved by the following technical solutions:

Containing the wig composite fibre coloring agent of amido silicon oil, this coloring agent is made up of the raw material of following weight portion: REACTIVE DYES 10-12, amido silicon oil 0.2-0.3, fatty alcohol-polyoxyethylene ether 0.2-0.3, polyvinyl alcohol 4-5, Sodium Polyacrylate 1-2, acetic acid/sodium acetate buffer are appropriate, CATION etherification starch 0.4-0.5, Sodium hydroxide q. s, deionized water 150-180.

Described a kind of wig composite fibre coloring agent containing amido silicon oil and preparation method thereof, its spy is, described preparation method is:

(1) first polyvinyl alcohol is added in the deionized water of 20-30 weight portion, be heated to 80-90 DEG C, be stirred to after it dissolves completely and be cooled to 40-50 DEG C, add CATION etherification starch subsequently, and be 7-8 by sodium hydrate regulator solution pH value, high-speed stirred hybrid reaction 2-3h, obtains cationized polyvinyl alcohol-etherification starch solution for standby;

(2) REACTIVE DYES is added in remaining deionized water, the aqueous solution is heated to 50-60 DEG C, add other residual components except acetic acid/sodium acetate buffer subsequently again, be uniformly mixed 40-50min, adding cationized polyvinyl alcohol-etherification starch solution prepared by step (1) subsequently again, is 7-7.5 by sodium hydrate regulator solution pH value, continues mix and blend reaction 40-50min, reaction terminates rear acetic acid/sodium acetate buffer regulator solution to neutrality, after being cooled to room temperature and get final product.

Advantage of the present invention is: with REACTIVE DYES preparation dye liquor, and utilize CATION etherification starch to carry out cationization process to polyvinyl alcohol, the active dye liquor that the polyvinyl alcohol of cationization and REACTIVE DYES prepare after reacting has high cementability and equalization, there are certain slow dye, protection effect, improve the Color of composite fibre, the amido silicon oil added has good adsorptivity and compatibility, it can improve feel and the mechanical strength of fiber after being combined with composite fibre, prevent that composite fibre is swelling in dyeing course to become fragile; Wig fiber colour after the coloring agent process utilizing the present invention to prepare is evenly firm, and feel is level and smooth, water-fastness dry-cleaning.

Detailed description of the invention

The coloring agent of this embodiment is made up of the raw material of following weight portion: REACTIVE DYES 10, amido silicon oil 0.2, fatty alcohol-polyoxyethylene ether 0.2, polyvinyl alcohol 4, Sodium Polyacrylate 1, acetic acid/sodium acetate buffer are appropriate, CATION etherification starch 0.4, Sodium hydroxide q. s, deionized water 150.

The preparation method of this coloring agent is:

(1) first polyvinyl alcohol is added in the deionized water of 20 weight portions, be heated to 80 DEG C, be stirred to after it dissolves completely and be cooled to 40 DEG C, add CATION etherification starch subsequently, and be 7 by sodium hydrate regulator solution pH value, high-speed stirred hybrid reaction 2h, obtains the etherified starch solution of cationized polyvinyl for subsequent use;

(2) REACTIVE DYES is added in remaining deionized water, the aqueous solution is heated to 50 DEG C, add other residual components except acetic acid/sodium acetate buffer subsequently again, be uniformly mixed 40min, adding the etherified starch solution of cationized polyvinyl prepared by step (1) subsequently again, is 7 by sodium hydrate regulator solution pH value, continues mix and blend reaction 40min, reaction terminates rear acetic acid/sodium acetate buffer regulator solution to neutrality, after being cooled to room temperature and get final product.

Protein-the polyacrylonitrile composite fiber of the present embodiment coloring agent to wig is carried out dyeing process, the dye-uptake of composite fibre reaches 97.5%, and water-fastness COLOR FASTNESS is Pyatyi, and composite fibre intensity is 3.5CN/dtex, and elongation at break is 42.5%; The composite fibre look obtained is spent seldom, and bright color is even, and feel is salubrious.
