Abstract
The invention discloses a low-temperature cashmere dyeing method adopting an ionic liquid for pretreatment. The method is characterized by after pretreating cashmere with an ionic liquid with volume concentration of 5-10%, using a dye with volume concentration of 5-10%, 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 pretreatment temperature is 80 DEG C; the bath ratio is 1:50 and water bathing time is 10-20 minutes; 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 low-temperature dyeing is 10.5% 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 ionic liquid.
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 ionic liquid, 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 ionic liquid, after using volumetric concentration to be 5% ~ 10% ionic liquid preliminary treatment the cashmere, the use volumetric concentration is 5% ~ 10% dyestuff, the glauber salt of 6g/l, the peregal of 8g/l 0, transfer pH value to 4 ~ 5, water-bath is added cryogenic booster dyeing down at 80 ℃.
Described preliminary treatment is in 80 ℃ of temperature, bath raio 1:50, water-bath 10 ~ 20min.
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%
Beneficial effect: compared with prior art, remarkable advantage of the present invention is: powerful dyeing than normal woolenless cloth exceeds 10.5 % after the low temperature dyeing of the present invention, 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
It is 5% ionic liquid that cashmere is used volumetric concentration, in 80 ℃ of temperature; bath raio 1:50, after the water-bath 10min preliminary treatment, the use volumetric concentration is 5% dyestuff; the glauber salt of 6g/l, the peregal of 8g/l 0; transfer pH value to 4, water-bath, and bath raio is 1:50; time 60min, the interpolation volumetric concentration is 0.5% cryogenic booster JL-D dyeing under 80 ℃.
Embodiment 2
It is 10% ionic liquid that cashmere is used volumetric concentration, in 80 ℃ of temperature; bath raio 1:50, after the water-bath 20min preliminary treatment, the use volumetric concentration is 10% dyestuff; the glauber salt of 6g/l, the peregal of 8g/l 0; transfer pH value to 5, water-bath, and bath raio is 1:50; time 80min, the interpolation volumetric concentration is 2% cryogenic booster ZJ-W dyeing under 80 ℃.
