Abstract
The invention discloses a low temperature dyeing method of wool fibers, which comprises the steps of (1) wool washing, (2) chlorination modification of wool, (3) protease treatment of the wool, and (4) low temperature dyeing treatment. Step (4) comprises the steps of reactive dyeing, post treatment, neutral cleaning, soap boiling and water washing. The method can obviously improve dyeing properties of the wool fibers, reduces energy consumption with the adoption of the low temperature dyeing, lowers the cost, and is greener, and more ecological, environment-friendly and economical.
Description
Technical field
The present invention relates to a kind of method of dyeing wool fibers at low temperature, be specially a kind of method of dyeing wool fibers at low temperature
,Belong to field of textiles.
Background technology
Wool is in dyeing course, because there is hydrophobic fine and close scale layer in the wool fibre appearance, hinders dyestuff to the absorption of wool fibre with to diffusion inside, so wool generally dyes under 98 ℃ hot conditions, can improve the diffusion rate of dyestuff like this.But high-temp dyeing is not only consumed energy greatly, has increased cost, and makes wool suffer the effect of heat and chemical agent, causes the wool yellowing, influences feel, gloss, the vividness of fabric, makes its powerful decline.
Summary of the invention
Goal of the invention: the object of the present invention is to provide that a kind of Color is good, little to fabric damage, the method for the dyeing wool fibers at low temperature of economic environmental protection.
In order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:
A kind of method of dyeing wool fibers at low temperature, described method is carried out as follows:
(1) washing wool:
(2) chlorination of wool modification;
(3) wool Protease Treatment;
(4) low temperature dyeing is handled.
Described step (1) is: wool is placed the scouring of wool liquid of 2 ~ 5g/L in 25 ℃ of constant temperature washing 20 ~ 30min, bath raio 1:15 again through washing, squeezes the branch that anhydrates after the washing, and oven dry is stand-by.
Described step (2) is: with the DCCA of washed wool with 4%owf, the pH value is 4, bath raio 1: 30, and 25 ℃, 40min carries out chlorination modified.
Described step (3) is: to press the alkali protease of 4% owf through chlorination modified wool, the pH value is 8～8.5, handles 50 ~ 60 min in 50 ~ 55 ℃ of constant temperature; Then at 1% owf, pH handles 15min in 70 ~ 80 ℃ in 4 the paregal O solution, makes enzyme deactivation, and branchs that anhydrate squeezed in washing then, dries.
Described step (4) is: reactive dyeing → post processing → neutralization cleaning → soap boiling → washing.
Described reactive dyeing be bright powder, 5% owf of ammonium sulfate, 3% owf of acetic acid, 2% owf of volumetric concentration 40%, 1% owf Shuangzi CATION, 3% owf receive the uniformly dyeing material especially, transferring pH is 6; bath raio 1: 20; in 40 ℃ of water-bath 30min, the speed with 2 ℃/min is warming up to 65 ~ 85 ℃ again.
Described post processing is the ammoniacal liquor with volumetric concentration 25%, and adjust pH is 8～9.
It is with 20 ~ 50ml that described neutralization is cleaned, the neutralization of the acetic acid of volumetric concentration 40%.
Beneficial effect: compared with prior art, remarkable advantage of the present invention is: the present invention can obviously improve the dyeability of wool fibre, adopts low temperature dyeing to reduce energy consumption, has reduced cost, more green, ecological, environmental protection, economy.
The specific embodiment
The present invention is further described below by specific embodiment; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
Embodiment 1
Wool is placed the scouring of wool liquid of 2g/L in 25 ℃ of constant temperature washing 20min, bath raio 1:15 again through washing, squeezes the branch that anhydrates after the washing, and oven dry is stand-by.With the DCCA of washed wool with 4%owf, the pH value is 4, bath raio 1: 30, and 25 ℃, 40min carries out chlorination modified.To press the alkali protease of 4% owf through chlorination modified wool, the pH value is 8, handles 50 min in 50 ℃ of constant temperature; Then at 1% owf, pH handles 15min in 70 ℃ in 4 the paregal O solution, makes enzyme deactivation, and branchs that anhydrate squeezed in washing then, dries.The wool that Protease Treatment is crossed is received the uniformly dyeing material especially with the Shuangzi CATION of the bright powder of the ammonium sulfate of the acetic acid of volumetric concentration 40%, 1% owf, 2% owf, 3% owf, 5% owf, 3% owf's, transferring pH is 6; bath raio 1: 20; in 40 ℃ of water-bath 30min, the speed with 2 ℃/min is warming up to 65 ℃ again.Use the ammoniacal liquor of volumetric concentration 25% again, adjust pH is 8.Use 20ml, the acetic acid neutralization of volumetric concentration 40%.Through soap boiling, washing, finish dyeing again.Treated wool oven dry namely can be used as textile.
