Abstract
The invention relates to a method for dyeing pure silk by regarding a rare earth material as a mordant. The adopted technical scheme is as follows: taking a bleaching liquor according to a bath ratio of 1: (25-35) and pre-treating at a temperature of 90 DEG C; washing the pre-treated pure silk with a water washing liquor for twice to three times; dewatering and drying the pure silk; taking a dye liquor according to a bath ratio of 1: (25-35), adjusting PH of the dye liquor to 3-3.5, heating the dye liquor to 50 DEG C; adding the dried pure silk in the dye liquor and heating to 90 DEG C at a temperature rise speed of 2 DEG C per each minute, keeping the heat for 30-40 min and then cooling to 70 DEG C; and adding a rare-earth solution to soak the pure silk for 10-15 min, then heating to 90 DEG C at a temperature rise speed of 2 DEG C per each minute, keeping the heat for 30-40 min, washing with clear water for twice to three times, dewatering and drying. By adopting the method for dyeing the pure silk by regarding the rare earth material as the mordant, disclosed by the invention, color fastness requirements needed by the production of green environment-friendly textiles not only can be satisfied, but pollution from the traditional mordants to the environment can also be avoided.
Description
Technical field
The present invention relates to field of textiles, particularly a kind of rare-earth substance that adopts is the colouring method of mordant to silk broadcloth.
Background technology
Silk broadcloth is graceful noble, good with the compatibility of skin, softness comfortable and easy to wear, and moisture absorption is warming, can effectively prevent skin disease.With natural plant dye dyeing green, environmental protection, can make the good character of silk broadcloth more perfect, become real " complete green fabric ", at back to nature, focus on environmental protection, advocate green and pursue personalized today, to the demand of this " complete green fabric ", will constantly increase.The existing long history of application of natural plant dye, but most of natural plant dye is low to the affinity of fiber, must just can anchor on fiber by mordant, completes the dyeing to fabric.In traditional mordant dyeing technique, conventional mordant is mostly heavy metal ion, as: copper, iron, chromium or aluminium etc.But, along with being subject to heavy metal ion content in forbidding and textiles, part kind in synthetic dyestuffs is restricted, and make to select new mordant to replace the vital task that traditional heavy metal ion becomes the ecological processing of current development textiles.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of employing rare-earth substance and as mordant, silk broadcloth is dyeed, both can meet the needed dyefastness requirement of production environmental protection textiles, the pollution that can avoid traditional mordant to bring environment again.
The technical solution used in the present invention is: the silk broadcloth dying method that the rare-earth substance of take is mordant, and step is as follows:
1) preliminary treatment: get bleaching liquid by bath raio 1:25～35, bleaching liquid is warming up to 98 ℃, add silk broadcloth, keeping temperature is 98 ℃, soaks 30～40 minutes; Described bleaching liquid consists of: in every 1 premium on currency, add 5～15g hydrogen peroxide, 2～3g soda ash, 1.5～2.5g paregal O and 2～4g sodium metasilicate;
2) washing: by pretreated silk broadcloth water washing lotion washing 2～3 times; Described water lotion is: getting clear water adjusting PH is 5.5～6.5;
3) dehydration: after washing, dehydration, dry;
4) dyeing: get dye liquor by bath raio 1:25 ~ 35, regulating the PH of dye liquor is 3～3.5, is warming up to 50 ℃, add through the 3rd) the dried silk broadcloth of step, with 2 ℃ to 98 ℃ of intensifications per minute, be incubated 30 ~ 40 minutes, then be cooled to 70 ℃, add earth solution, soak 10 ~ 15 minutes, then with 2 ℃ to 98 ℃ of intensifications per minute, be incubated 30～40 minutes, with clear water, clean 2～3 times, dehydration, dry.
Above-mentioned take the silk broadcloth dying method that rare-earth substance is mordant, being formulated as of dye liquor: in every 1 premium on currency, add 0.05～7g vegetable colour; Preferably, vegetable colour is safflower, Asian puccoon, Chinese gall, indigo, lac is red, Gardenia Yellow, gardenia blue or safflower yellow.
The present invention adopts rare-earth substance as mordant, and preferred rare-earth substance is Pr
