CN101392459A - Finishing auxiliary agent of natural hair and artificial fiber curving hair - Google Patents

Abstract

The invention discloses an after-finishing auxiliary for natural hair and artificial curved hair. The auxiliary is novel quarternary ammonium salt silicone after-finishing agent, and consists of alkyl quarternary ammonium salt, emulsifying agent, a silica gel elastic body, amido silicone oil or modified amido silicone oil, modified organic silicone, polyvinyl alcohol and ramifications thereof. The preparation of the auxiliary includes the following steps: evenly mixing the quarternary ammonium salt, the emulsification ingredient and proper amount of water in an emulsion machine at the temperature of 70-90 DEG C to obtain transparent and even liquid, then cooling the temperature to 60 DEG C, then regulating the PH value to weak acid, and adding the amido silicone oil, keeping an isothermal reaction for 0.5-1.5 hours and then cooling and neutralizing to obtain the finished product. The accessory ingredient has strong soaking penetrability, good absorbing, filming and humidity-keeping function, can lead the curved hair fiber to be soft, smooth, bright and elastic, leads the fiber to be stainless and antistatic, and realizing perfect finishing effect.

Description

A kind of natural hair and artificial fiber curly hair after-treating auxiliary

Technical field

The invention belongs to after-treating auxiliary of the band curvature product that chemical fields such as natural and artificial fiber use and its production and application.Be particularly related to methods and applications that use the emulsification compounded technology to prepare a kind of multifunctional modification organic silicone emulsion.

Background technology

Feel is people's summaries to some fibre textile fabrics sense of touch comprehensive characteristics in long-term practice, is a kind of sense feature.In recent years, along with The development in society and economy, people are strong day by day to the personalization of fibre (particularly fiber hair hair products), superior and diversified requirement, make the fibre of high sense organ gain great popularity.Submissive smooth hand feeling feature can not satisfy people's demand, and the bright and clean external appearance characteristic such as lasting of external beautiful design, flexible, the curvature of light is more paid close attention to.

Before fibre is finished, mostly will carry out impregnation process through various auxiliary agents, its principle is to rely on the effect of assistant for immersing, and can form one deck auxiliary agent film at fiber surface and give product various good performances, thus the quality scale and the added value of raising product.What middle nineteen nineties grew up is the organic silicone finishing agent of major constituent with aminoethyl aminopropyl silicone oil, substantially can satisfy the demand of domestic market, but be subjected to the hydrophobic restriction of silicone softening agent, fibre after the arrangement has static electrification, inhale ash, shortcomings such as curvature is easily at random lastingly, and hand feel performance is single.For overcoming above-mentioned drawback, the present invention adopts and introduces amino carry out modification in the organosilicon main chain, improves that it is water-soluble, and that composite adding simultaneously has is antistatic, soft, smooth, the composition of elasticity, function such as bonding, makes it reach perfect finishing effect.

Summary of the invention

1, the object of the invention is to provide a kind of good curly hair fiber finishing additive.The basic point of departure of each component minor structure of after-treating auxiliary of the present invention and prescription design is: by the post processing impregnation technology, antistatic, bonding, high-elastic to the fibre property contribution, preserve moisture, performance such as bright, soft, smooth, antifouling.The combination of these performances is not simplely between several functional products to add and concern yet, exist complicated consonance effect between them, also exist several to repelling the negative effect of offsetting each other, therefore seek appropriate equalization point, various performances are fully showed on this optimization equalization point, and promptly optimum formula determines it is the key of this inventive concept success.

2, after-treating auxiliary provided by the invention, contain following composition:

(1) 5～30% alkyl quaternary amine salt;

(2) 1～10% emulsifying agent;

(3) 5～20% silica gel elastomer;

(4) 5～30% amido silicon oil or modified amino silicon oil;

(5) 5～20% modified organic silicon ketone;

(6) 1～5% polyvinyl alcohol and derivative thereof.

Can be mixed with the emulsion of different whites of moisture difference or blueing light with viscosity by above-mentioned prescription.

The object of the present invention is to provide a kind of composite preparation method of emulsification of above-mentioned auxiliary agent.

The present invention can adopt the preparation of following method, and the concrete operations step is: at 70 ℃--under 90 ℃, quaternary amine and emulsified component and an amount of water stirring and evenly mixing in mulser, obtain transparent and uniform liquid, be cooled to 60 ℃, after the adjusting pH value is faintly acid, add amido silicon oil.Isothermal reaction 0.5～1.5H can obtain product after the cooling neutralization.

3, another object of the present invention is to provide a kind of after-treating auxiliary to use impregnation technology.The steps such as---moulding---oven dry that mainly comprise immersion.Concrete operations are as follows:

(1) pending fiber is fully immersed in the maceration extract that is added with this finishing auxiliaries, parameter is as follows:

Consumption 5--10% (o.w.f)

Bath raio 1: 10--15

Soaking temperature 25--30 ℃

Soak time 15-20min

(2) fiber behind the dipping is taken out, finish certain curvature moulding as required after, oven dry gets final product.

4, the present invention has following beneficial effect:

Be a kind of modified organic silicon ketone finishing agent, production equipment is simple, and cost is low.Can with water arbitrarily than dilution, flood easy to usely, particularly natural hair and the artificial fiber that needs the curvature moulding in the postprocessing working procedures had good finishing effect.
