Abstract
The invention discloses a low-temperature cashmere dyeing method adopting ethanolamine for pretreatment. The method is characterized by pretreating cashmere with ethanolamine at a concentration of 6-10g/l at 30 DEG C in a bath ratio of 1:50, carrying out water bathing for 10-20 minutes, carrying out steaming for 5-10 minutes at 100 DEG C, after pretreatment, using a dye with volume concentration of 5-10%, adding 6g/l anhydrous sodium sulfate and 8g/l peregal 0, regulating the pH value to 4-5, carrying out water bathing and adding a low-temperature aid for dyeing at 80 DEG C, wherein the dye is an acid dye or a reactive dye; the bath ratio of water bathing in the dyeing step is 1:50 and the time is 60-80 minutes; the low-temperature aid is JL-D or ZJ-W; and the volume concentration of the low-temperature aid is 0.5-2%. The method has the obvious advantages that the strength of the yarns after dyeing is 15% higher than that after normal dehaired wool dyeing; the yarn spinnability can be greatly improved; and the damages of dyeing to fibers can be reduced.
Description
Technical field
The present invention relates to a kind of cashmere low-temperature dyeing method, specifically is the pretreated cashmere low-temperature dyeing method of a kind of employing monoethanolamine.
Background technology
Cashmere fiber is behind normal dyeing, yarn strength in spinning process, often occurs and do not reach standard-required, even be lower than the situation of standard 20% to 30%, and problems such as top, garment piece broken hole appear falling in the braiding process, have a strong impact on quality and the manufacturing schedule of product.
Summary of the invention
Goal of the invention: the object of the present invention is to provide the preliminary treatment of a kind of employing monoethanolamine, by low temperature dyeing, improve worsted cashmere yarn row yielding, improve spinnability, reduce the method for the damage that dyeing causes fiber.
In order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:
The pretreated cashmere low-temperature dyeing method of a kind of employing monoethanolamine is the monoethanolamine preliminary treatment of 6 ~ 10g/l with the cashmere working concentration, and in 30 ℃ of temperature; bath raio 1:50; water-bath 10 ~ 20min, and in 100 ℃, decatize 5 ~ 10min; after the preliminary treatment; the use volumetric concentration is 5% ~ 10% dyestuff, adds the glauber salt of 6g/l, the peregal 0 of 8g/l, transfers pH value to 4 ~ 5; water-bath adds cryogenic booster down at 80 ℃ and dyes.
Described dyestuff is ACID DYES or REACTIVE DYES.
Described ACID DYES is Acid Brilliant Scarlet GR, acid navy blue 5R or Weakly Acid Black BR.
But but but described REACTIVE DYES is Dolly Supreme Being orange WNGR, the dark blue WP of Dolly Supreme Being or the black WG of Dolly Supreme Being.
The bath raio of water-bath is 1:50 in the described staining procedure, time 60 ~ 80min.
Described cryogenic booster is cryogenic booster JL-D or cryogenic booster ZJ-W.
The volumetric concentration of described cryogenic booster is 0.5% ~ 2%.
The principle of the invention is: wool is subjected to the effect of monoethanolamine, can generate amino alanine, has increased and has dyed seat; Disulfide bonds in the wool, its structure becomes more loose, for dyestuff provides convenience to the fibrous inside diffusion; Monoethanolamine is alkalescence, can change the surface-activity of wool, promotes wool to the absorption of dyestuff; Monoethanolamine has certain effect to the stripping of binding between horn cell, increased the passage that dyestuff enters wool fibre, and dye-uptake is increased.
Beneficial effect: compared with prior art, remarkable advantage of the present invention is: the present invention adopts the monoethanolamine preliminary treatment, and powerful dyeing than normal woolenless cloth exceeds 15 % after the low temperature dyeing, can greatly improve the yarn spinnability, reduces the damage that dyeing causes fiber.
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
Be the monoethanolamine preliminary treatment of 6g/l with the cashmere working concentration, in 30 ℃ of temperature, bath raio 1:50, water-bath 10min, and in 100 ℃, decatize 5min, after the preliminary treatment, the use volumetric concentration is 5% Acid Brilliant Scarlet GR dyestuff, and the glauber salt of 6g/l, the peregal of 8g/l 0 are transferred pH value to 4, water-bath; bath raio is 1:50, time 60min, the interpolation volumetric concentration is 0.5% cryogenic booster JL-D dyeing under 80 ℃.
Embodiment 2
Be the monoethanolamine preliminary treatment of 10g/l with the cashmere working concentration, in 30 ℃ of temperature, bath raio 1:50, water-bath 20min, and in 100 ℃, decatize 10min, after the preliminary treatment, but the use volumetric concentration is Dolly Supreme Being's orange WNGR dyestuff of 10%, and the glauber salt of 6g/l, the peregal of 8g/l 0 are transferred pH value to 5, water-bath; bath raio is 1:50, time 80min, the interpolation volumetric concentration is 2% cryogenic booster ZJ-W dyeing under 80 ℃.
