Abstract
The invention discloses a cashmere loose fiber and a cashmere strip staining method. The method comprises the following steps of: A, performing acetone impregnation; B, performing plasma treatment; C, staining by using a staining solution containing 3-7 weight percent of liquid dye, 1-2 weight percent of a protective agent, 1-1.5 weight percent of a dye leveler, 2-3 weight percent of 1-methoxy-2-propyl alcohol, 0.5-1 weight percent of propylene glycol block polyether, 0.8-1.5 weight percent of a penetrating agent JFC, 5-10 weight percent of anhydrous sodium sulfate and 20-30 weight percent of isopropyl alcohol; D, soaping by using a 2-3 weight percent of SKDA aqueous solution; E, performing yarn steaming by adopting 100% saturated vapor; and F, cooling and drying. The damage of the staining process on the cashmere is reduced by utilizing the low-temperature staining process, and the staining vividness and color fastness are improved through ultrasonic oscillation and yarn steaming process.
Description
Technical field
The present invention relates to the stock-dye technical field, the colouring method of especially a kind of cashmere bulk fibre and suede bar.
Background technology
Cashmere is to be grown in goat appearance cortex, covers the very thin fine fleece of one deck at goat coarse wool root, belongs to rare special animal fiber.The good quality of cashmere is that human existing textile raw material is all incomparable.
Cashmere product belongs to grade textiles, and finished product requires bright-colored, and should reach International Wool Secretariat's " machine washable " international standard.But because the cashmere its specific structure causes common colouring method can cause the tensile property of cashmere and feel to descend, the COLOR FASTNESS of dyeing also can't reach higher level, has influenced the quality of cashmere product.
Summary of the invention
The technical problem to be solved in the present invention provides the colouring method of a kind of cashmere bulk fibre and suede bar, can solve the deficiencies in the prior art, utilize the technology of low temperature dyeing, reduced the damage of dyeing course to cashmere, by supersonic oscillations and yarn steaming technology, improved vividness and the COLOR FASTNESS of dyeing.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
The colouring method of a kind of cashmere bulk fibre and suede bar, step is as follows:

Cashmere is put into acetone flooded 1.5～2 hours, take out the cashmere air dry;
B, Cement Composite Treated by Plasma
Dried cashmere was carried out Cement Composite Treated by Plasma 2～3 minutes;
C, dyeing
To carry out cashmere after the Cement Composite Treated by Plasma puts into dyeing liquor and soaked 1 hour, the temperature of dyeing liquor at the uniform velocity is increased to 50 ℃ from 30 ℃ in immersion process, soak and in dyeing liquor, add supersonic oscillations after 1 hour, keep 50 ℃ temperature 1～1.5 hour, stir simultaneously;
The constituent of dyeing liquor comprises: the penetrating agent JFC of 1-methoxyl group-2-propyl alcohol of the dye leveller of the liquid dyes of 3～7wt%, the protective agent of 1～2wt%, 1～1.5wt%, 2～3wt%, the propylene glycol block polyether of 0.5～1wt%, 0.8～1.5wt%, the anhydrous sodium sulfate of 5～10wt%, the isopropyl alcohol of 20～30wt%, surplus are water;
In the forward direction dyeing liquor that dyes, add sour ph value with dyeing liquor and be adjusted to 4.0～5.0;
Bath raio during dyeing is 10:1～12:1;
D, soap
The SKDA aqueous solution that cashmere after the dyeing is put into 2～3wt% carries out rinsing, adds sodium carbonate simultaneously and neutralizes, and the ph value of the liquid after the rinsing is adjusted to 6.5～7.5, and the temperature of rinsing remains on 50 ℃;
E, yarn steaming
Serviceability temperature is that 60 ℃ 100% saturated vapor was handled 10 minutes the cashmere of soaping later, and serviceability temperature is that 75 ℃ 100% saturated vapor was handled 20 minutes cashmere then;
F, oven dry
The cashmere that carries out after yarn steaming is handled was dried 2～3 hours, and bake out temperature at the uniform velocity is reduced to 30 ℃ from 75 ℃, and the oven dry wind speed is 3～5m/s.
As a kind of optimal technical scheme of the present invention, described plasma adopts the glow discharge mode to produce, and reacting gas is oxygen.
As a kind of optimal technical scheme of the present invention, described protective agent is dimethylol ethylene urea.
Be a kind of optimal technical scheme of the present invention, described acid is formic acid.
Be a kind of optimal technical scheme of the present invention, described dye leveller is peregal-O.
Be a kind of optimal technical scheme of the present invention, the frequency of described supersonic oscillations is 45kHz.
Be a kind of optimal technical scheme of the present invention, the speed of described stirring is 4r/min.
The beneficial effect that adopts technique scheme to bring is: by using plasma cashmere is carried out preliminary treatment, can make the big molecular scission on cashmere surface, form ion or free radical, reduced dyeing temperature effectively, reduced the damage of dyeing course to cashmere.The maximum stretching resistance of cashmere, fracture tensile elongation and fibre length all can remain on below 5% at the damage ratio after the dyeing.By appropriate design dyeing liquor proportioning and add supersonic oscillations, dye-uptake can be increased to more than 99.7%, degree of fixation is increased to more than 99.5%.By the processing of yarn steaming, COLOR FASTNESS can be stabilized in the 4-5 rank.
The specific embodiment
The colouring method of a kind of cashmere bulk fibre and suede bar, step is as follows:
A, dipping
Cashmere is put into the acetone dipping 1.5 hours, take out the cashmere air dry;
