Abstract

The invention discloses a black hair bleaching method. The black hair bleaching method is characterized by comprising the following steps that firstly, black hair is processed through potassium peroxodisulfate to erode scale layers of the black hair and break part of natural pigment; secondly, the black hair is processed through formamidinesulfinic acid, the natural pigment in the black hair is reduced through higher reduction potential in the formamidinesulfinic acid, the further bleaching effect is achieved on the black hair, therefore, the better decoloring effect is obtained, and the better power is maintained.

Description

A kind of black drift color method

technical field:

The present invention relates to a kind of black drift color method, especially relate to a kind of adopt potassium peroxydisulfate and first to narrow sulfinic acid Combined Treatment carries out floating look method to black.

background technology:

Wig is described as " on head fashionable dress ", as the exported product that a kind of added value is higher, 19 beginnings of the century by the Jew in Germany start to walk manage, after be progressively transferred to Korea Spro, day and Hong Kong and Taiwan.After reform and opening-up, the domestic industry transfer accepting Korea S in batch, wig manufacturing enterprise once made a living with original equipment manufacturer and imitation, at present, China be in the world maximum wig produce, exported country, increasing wig export enterprise participates in the competition of overseas market.Along with wig overseas market changes in demand is more and more faster, market competition is more and more white-hot, and wig enterprise especially export-oriented enterprise more needs to improve the quality of products to enhance one's market competitiveness.

The raw material making wig has Zhen Fa and chemical fibre two kinds, and high-quality wig popular in the market substantially all true sending out is made.Black is a kind of natural protein fibre, and the pigment in black is present in fibrage, and due to hair Microstructure of epidermal scale, carrying out drift look to hair, not injure again fiber be very difficult.Tradition drift look technique mainly adopts hydrogen peroxide to process, and condition is comparatively violent, and fibre damage is serious, and the hair feel after impaired is coarse, and brute force declines.Because client is more and more wider to the demand of color development and range of choice, therefore develop gentleness, protect black strong drift look technology there is good researching value and application prospect.

summary of the invention:

The invention provides a kind of chromatic effect that floats good and black better powerful drift color method can be kept.

The technical scheme that the present invention takes is as follows, and a kind of black drift color method, is characterized in that: comprise the steps:

(1) by potassium peroxydisulfate treatment process, scale layer and the part natural colouring matter of black is destroyed;

(2) narrow sulfinic acid process by first, vat black send out in natural colouring matter, and produce further drift look effect to black.

Operation principle of the present invention is as follows:

Because hair surface exists Microstructure of epidermal scale, the drift look of hair is made to become comparatively difficulty.Applicant is found by research: utilize the newborn oxygen of potassium peroxydisulfate decomposition releasing that hair scale layer is had to destruction and checks colors and have the principle of decolorization, potassium peroxydisulfate process is first adopted to corrode hair scale layer, the cystine in scale is made to be oxidized to cysteine, with the hydrolysis of peptide chain, scale is partly divested, then narrow sulfinic acid to black drift look process further by first again, the effect of more outstanding bleaching can be obtained, narrowed the synergy of sulfinic acid by potassium peroxydisulfate and first, make black prosperity to floating chromatic effect preferably and keeping powerful preferably.

As preferred version of the present invention, adopt following technique can obtain more outstanding bleaching effect:

In step (1), described potassium peroxydisulfate treatment process comprises: the preparation of (1) treatment fluid: potassium peroxydisulfate consumption is 3-8%owf, sulfuric acid 1%, and bath raio 1:50, is modulated into treatment fluid; (2) process conditions: under the condition of temperature 30-40 DEG C, are immersed in treatment fluid 20-40 minute by black, washing.

In step (2), described first is narrowed sulfinic acid treatment process and is comprised: (1) technology preparation: first narrows sulfinic acid 3-15%, sodium phosphate trimer 4%, bath raio 1:50; (2) process conditions: under the condition of temperature 40-70 DEG C, are immersed in treatment fluid 1-8 hour by black, washing, dry.

Percentage composition in step (1), (2), apart from outside special instruction, all refers to its mass percentage in treatment fluid.

Technique effect of the present invention is as follows:

(1) better chromatic effect is floated:

Hair scale layer is corroded owing to first adopting potassium peroxydisulfate process, make the cystine in scale be oxidized to cysteine, with the hydrolysis of peptide chain, scale is partly divested, then narrow sulfinic acid to black drift look process further by first again, the effect of more outstanding bleaching can be obtained.

(2) hair damage is little, and strength retention is high:

Prove by experiment, adopt potassium peroxydisulfate and first to narrow the synergy of sulfinic acid, while making black prosperity to good drift chromatic effect, the fracture strength loss for hair is little, and the hair after drift look still keeps good brute force.

Below in conjunction with embodiment, the present invention is described in further detail:

detailed description of the invention:

embodiment 1:

Adopt potassium peroxydisulfate and first to narrow sulfinic acid Combined Treatment and carry out drift look to black, method is as follows:

(1), potassium peroxydisulfate consumption is 5%owf, sulfuric acid 1%, and bath raio 1:50, is modulated into treatment fluid, under the condition of temperature 40 DEG C, is immersed in treatment fluid 60 minutes by black, washing.

(2), then narrow sulfinic acid 8% by first, sodium phosphate trimer 4%, bath raio 1:50, under the condition of temperature 60 C, black is immersed in treatment fluid 2 hours, washing, dry.The results are shown in Table 1.

Table 1, untreated hair and drift look hair performance comparison.

embodiment 2:

The process of independent employing potassium peroxydisulfate carries out drift look to black, and method is as follows:

Potassium peroxydisulfate consumption is 5%owf, sulfuric acid 1%, and bath raio 1:50, is modulated into treatment fluid, under the condition of temperature 40 DEG C, is immersed in treatment fluid 60 minutes by black, washing.The results are shown in Table 2.

Table 2, untreated hair and drift look hair performance comparison.

embodiment 3:

Independent employing first is narrowed sulfinic acid process and is carried out drift look to black, and method is as follows:

First narrows sulfinic acid 8%, sodium phosphate trimer 4%, bath raio 1:50, under the condition of temperature 60 C, black is immersed in treatment fluid 2 hours, washing, dries.The results are shown in Table 3.

Table 3, untreated hair and drift look hair performance comparison.

Sample	Aberration	K/S	Breaking strength retention	Color
					Untreated black	-	30.74	-	Black
Drift look hair	29.51	12.26	96.2%	Light yellow

analyze:

The drift look hair processed respectively by embodiment 1-3, compares with untreated black, can find:

1, separately adopt potassium peroxydisulfate process, have certain bleaching effect but not good, the hair color after process becomes pitchy by original black, and the fracture strength loss of hair is little;

2, adopt first to narrow sulfinic acid and sodium phosphate trimer process, bleaching effect comparatively potassium peroxydisulfate increases, but hair color still can only reach light yellow;

3, employing is first carried out potassium peroxydisulfate process, is narrowed sulfinic acid and sodium phosphate trimer process through first again, because potassium peroxydisulfate first can destroy scale layer and the part natural colouring matter of black; Then narrow sulfinic acid process by first, vat black send out in natural colouring matter, and produce further drift look effect to black, therefore, can obtain more excellent bleaching effect, it is even white that hair color can reach rice white, and the loss of the fracture strength of hair is less, meets instructions for use.
