Abstract
The invention relates to a method for dyeing green silk fabrics by sodium copper chlorophyllin. The dyeing method is a direct dyeing method without using mordant, and the parameters of the dyeing process are as follows: the bath ratio is 1:30-50, the pH value of a dye bath is 7 to 9, the dyeing temperature is 70 to 90 DEG C, the heat-insulating dyeing time is 60 to 120min, and the weight of the sodium copper chlorophyllin accounts for 1 to 3 percent of that of the silk fabric to be dyed; NaCl additives can simultaneously be added into the dye bath, and the application amount thereof is 2-8g/L, the NaCl additives and the sodium copper chlorophyllin can be simultaneously added into the dye bath for one time or for times. The sodium copper chlorophyllin in the invention is safe and non-toxic, and is widely used in food colourants; and the green silk fabrics dyed by the sodium copper chlorophyllin are vivid and bright, and can be used in the development of high-grade pure silk underwear.
Description
Technical field
The present invention relates to a kind of method of natural dye green colouring silk fabric, especially relate to a kind of method of sodium copper chlorophyllin green colouring silk fabric, belong to natural dye and dye the silk field.
Background technology
Along with the raising of people's health care consciousness and quality of life, more and more higher to the security requirement of garment material.Safety non-toxic, renewable, eco-friendly natural dye are favored by people more, have vast potential for future development.
Adopt natural dye dying to have a long history in China.Reportedly, China is as far back as Yellow Emperor, a legendary ruler period, and people just can utilize the juice dyeing of plant.Archaeologist nineteen fifty-nine, for the silk thread of finding to have dyeing the grave, this explanation can be adopted natural dye dying in the Yin Dynasty for people at least from abundant mouthful of Yin Dynasty of Earthquake of Anyang station in Henan king.China people are accumulating many experiences in the extensive use process to vegetable colour for thousands of years, such as can propose curcumin from ginger juice, can propose hematoxylin etc. from bush.
Vegetable colour especially is suitable for the silk broadcloth dying of small lot, top grade, and it not only can improve the silk broadcloth value-added content of product, and can attract the consumer colonies of advocating health, green idea to choose the silk broadcloth product more.
Press by the color classification of dyeing and weaving thing gained, it is vegetable colour that natural dye can be divided into blue system, yellow system, red colour system, violet, dark brown and brown system, grey and black.In the natural dye of having added up with yellow, blue, red kind is more, and is green and black is less.Adopt yellow, blue two kind of plant dyestuffs by the cover dyeing method can dye green-fabrics, but resisdye complex process, dyeing time is long, the green vividness of institute's dyeing and weaving thing is relatively poor.Chlorophyll is the stereon that extensively is present in the plant, but very unstable.With spinach or silkworm faeces is raw material, extracts chlorophyll with acetone or alcohol, and the sodium copper chlorophyllin that makes through copper generation, saponification is a kind of very metalloporphyrin of high stability that has, and is blackish green powder, strong coloring force, and color and luster is beautiful.At present, sodium copper chlorophyllin has been widely used as fields such as food additives, cosmetic additive agent, food and medicine colouring agent.
Summary of the invention
The present invention is intended to adopt the chlorophyll copper sodium salt pair silk fabric of aboundresources, safety non-toxic to dye, with the green silk fabric that dyes bright in colour, beautifully.
For achieving the above object, the present invention adopts following technological process that silk fabric is dyeed: silk fabric → come unstuck → clean → chlorophyll copper sodium salt dyeing → washing.
Silk fabric of the present invention adopts the Carbon Dioxide sodium solution to come unstuck, its technological parameter is as follows: the Carbon Dioxide sodium solution of 0.5-1g/L; bath raio 1: 50; 100 ℃ of temperature; boil and boil 30-60min; the silk fabric after coming unstuck respectively with 95 ℃ of deionized water washings, 60 ℃ of deionized water washings for several times, and is clean with cold water flush at last.
It is as follows that sodium copper chlorophyllin of the present invention dyes the silk technological parameter: dye bath ratio 1: 30-50, dye bath pH value 7-9, dyeing temperature 70-90 ℃, insulation dyeing time 60-120min, sodium copper chlorophyllin dye dosage wait to dye the 1-3% of silk fabric weight; Add the NaCl salt assitant simultaneously, its consumption is 2-8g/L, can once add dye bath simultaneously with the chlorophyll copper sodium salt dyestuff, also can gradation add dye bath.Dye bath pH value selects 7-9 to be because the chlorophyll copper sodium salting liquid can precipitate under acid condition, silk fiber itself is not alkaline-resisting, property or weak basic condition dyeing down hereinto, the silk fabric that sodium copper chlorophyllin can dye bud greenly.In dyeing course, add the NaCl salt electrolyte, this is because under dye bath pH=7-9 condition, silk fiber is electronegative, the chlorophyll copper sodium dye molecule is also electronegative, the NaCl salt electrolyte can reduce the electrostatic repulsion forces between electronegative dye molecule and the fiber molecule, improves the absorption of dyestuff to fiber.
Specific embodiment
Sodium copper chlorophyllin dyes silk fabric specific embodiment 1
Adopt the Carbon Dioxide sodium solution of distilled water preparation 1g/L, the silk fabric that will come unstuck at 1: 50 with bath raio adds in the solution, 100 ℃ boil and boil 30min in thermostat water bath, then respectively for several times with 95 ℃ of deionized waters, 60 ℃ of deionization washings, with cold water flush for several times, residual alkali lye, salt ion and sericin on silk fabric are removed fully at last.Adopt the sodium copper chlorophyllin dye liquor that the silk fabric after coming unstuck is dyeed; bath raio 1: 50; sodium copper chlorophyllin dye dosage 3% (o.w.f) (dye dosage is the percentage that chlorophyll copper sodium salt dyestuff weight accounts for silk fabric weight), 70 ℃ of dyeing temperatures, insulation dyeing 120min.Silk fabric after the dyeing adopts flushing with clean water not wash out to there being loose colour.
Sodium copper chlorophyllin dyes silk fabric specific embodiment 2
Adopt the Carbon Dioxide sodium solution of distilled water preparation 0.5g/L, the silk fabric that will come unstuck at 1: 50 with bath raio adds in the solution, 100 ℃ boil and boil 60min in thermostat water bath, then respectively with 95 ℃ of deionized waters, 60 ℃ of deionized water washings, with cold water flush for several times, residual alkali lye, salt ion and sericin on silk fabric are removed fully at last.Adopt the sodium copper chlorophyllin dye liquor that the silk fabric after coming unstuck is dyeed; bath raio 1: 30; sodium copper chlorophyllin dye dosage 2% (o.w.f) (dye dosage is the percentage that chlorophyll copper sodium salt dyestuff weight accounts for silk fabric weight), 80 ℃ of dyeing temperatures, insulation dyeing 90min.Silk fabric after the dyeing adopts flushing with clean water not wash out to there being loose colour.
