Abstract

The invention discloses a kind of bleaching process of purple cashmere, including cashmere cleaning, ferrous complexing, oxidative decoloration and reduction four steps, the bleaching process of the purple cashmere increases ferrous complexation approach, pigment can be complexed to form chelate with ferrous ion in purple cashmere, it is bleached again by redox, purple cashmere is overall white after bleaching, and cashmere fiber whiteness significantly improves and weight loss control is within 5%, and the influence to cashmere configuration and structure strength is smaller.

Description

A kind of bleaching process of purple cashmere
Technical field
The present invention relates to cashmere processing technology fields, and in particular to a kind of bleaching process of purple cashmere.
Background technique
Cashmere is thin and curved fiber one by one, wherein containing many air, and forms air layer, can be defendd outer Carry out the invasion of cold air, retaining body temperature will not lower.Cashmere is thinner than wool very much, and outer scale is also finer and closely woven than wool, smooth, because This, light-weight, soft, good toughness.It is particularly suitable for manufacturing underwear, it is light, soft, soft, sliding when wearing next to the skin, as snug as a bug in a rug.
Purple suede means black goat suede produced, and the black wool and suede color in purple suede are more clearly demarcated, traditional production technology benefit It is produce dark product with the purple of looks more, but the whiter suede of its yield is much higher, and on the market for the demand of Aries suede It is larger.Decoloration process directlys adopt hydrogen peroxide oxidation decoloration more in the prior art, but decolorizing effect is poor, to the fiber of cashmere Intensity effect is larger.Therefore, one of the technical issues of how purple suede being bleached the colour of camel's hair, be puzzlement those skilled in the art.
Summary of the invention
It is an object of the present invention to overcoming defect existing in the prior art, a kind of bleaching work of purple cashmere is provided Skill, the cashmere after above-mentioned decolorization have good whiteness and preferable dyeability.
To achieve the above object, the technical solution of the present invention is as follows: a kind of bleaching process of purple cashmere, which is characterized in that packet Include following steps:
S1: cleaning cashmere, drying;
S2: cashmere obtained by S1 is placed in enveloping agent solution, and based on cashmere weight, the composition of enveloping agent solution includes 3~5owf% Ferrous sulfate, the citric acid of 2~3 owf %, the sodium hydrosulfite of 2.5~4 owf%, 2.5~4 owf% polyethylene glycol 400s, 50~ 60 DEG C of 2~3h of water-bath take out cashmere, drying;
S3: cashmere obtained by S2 is placed in containing hydrogen peroxide stabilizer, weak acid, 30%H2O2Oxidative decoloration solution in, 50~60 DEG C 2~3h of water-bath, the pH value of oxidative decoloration solution are 6.7~7, wash cashmere;
S4: cashmere obtained by S3 is placed in insurance amidin and is rinsed at least twice, the cashmere of bleaching is obtained.
Preferred technical solution is, hydrogen peroxide stabilizer is that poly- a- hydroxy acrylic acid salt, polyacrylamide are steady in S3 Determine one of agent or two or more combinations.
Preferred technical solution is that weak acid is selected from one of orthophosphoric acid, formic acid, acetic acid and benzoic acid or two in S3 Kind or more combination.
Preferred technical solution is 30%H in S32O2Dosage be 10~15 owf %, the 30%H2O2For the side of dropwise addition Formula is added in S3 reaction system.
Preferred technical solution is to clean cashmere using acetone in S1.
The advantages and beneficial effects of the present invention are:
The bleaching process of the purple cashmere increases ferrous complexation approach, and pigment can be complexed to be formed with ferrous ion in purple cashmere Chelate, then bleached by redox, purple cashmere is overall white after bleaching, cashmere fiber whiteness significantly improve and Weight loss controls within 5%, and the influence to cashmere configuration and structure strength is smaller.
Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is further described.Following embodiment is only used for more Add and clearly demonstrate technical solution of the present invention, and not intended to limit the protection scope of the present invention.
Embodiment 1
The bleaching process of the purple cashmere of embodiment 1 the following steps are included:
S1: cleaning cashmere, drying;
S2: cashmere obtained by S1 is placed in enveloping agent solution, and based on cashmere weight, the composition of enveloping agent solution includes 3owf%'s Ferrous sulfate, the citric acid of 3 owf %, the sodium hydrosulfite of 2.5 owf%, 4 owf% polyethylene glycol 400s, 50 DEG C of water-bath 2h take out sheep Suede, drying;
S3: cashmere obtained by S2 is placed in containing hydrogen peroxide stabilizer, weak acid, 30%H2O2Oxidative decoloration solution in, 60 DEG C of water-baths 2h, the pH value of oxidative decoloration solution are 7, wash cashmere;
S4: cashmere obtained by S3 is placed in insurance amidin and is rinsed at least twice, the cashmere of bleaching is obtained.
Hydrogen peroxide stabilizer is sodium metasilicate in S3
Weak acid is selected from one of orthophosphoric acid, formic acid, acetic acid and benzoic acid or two or more combinations in S3.
30%H in S32O2Dosage be 10 owf %, hydrogen peroxide is directly added into oxidative decoloration solution.
The aqueous solution that 8 owf % of lauric acid diethyl amide is used in S1, is heated to 45 DEG C of cleaning cashmere.
Embodiment 2
Embodiment 2 the difference from embodiment 1 is that: the composition of S2 enveloping agent solution includes the ferrous sulfate of 5owf%, 2owf % Citric acid, the sodium hydrosulfite of 4 owf%, 2.5owf% polyethylene glycol 400,50 DEG C of water-bath 3h;
50 DEG C of water-bath 3h in S3, the pH value of oxidative decoloration solution are 6.7;
Hydrogen peroxide stabilizer is poly- a- hydroxy acrylic acid brine in S3.Weak acid is orthophosphoric acid in S3.30%H in S32O2Dosage be 10owf %, 30%H2O2It is added in S3 reaction system for the mode of dropwise addition.
Embodiment 3
Embodiment 3 the difference from embodiment 1 is that: S2 enveloping agent solution composition include 4owf% ferrous sulfate, 2.5owf % Citric acid, the sodium hydrosulfite of 3.2owf%, 3.2owf% polyethylene glycol 400,55 DEG C of water-bath 2.5h;
