Abstract
The present invention relates to low temperature environment protection dispersing dye which is particularly suitable for printing and dyeing polyester material and vinegar fiber material. The low temperature environment protection dispersing dye of the present invention is composed of the following components by the weight proportion: 15 to 50% of dye monomer A, 3 to 25% of dye monomer B and an auxiliary agent as the rest. The low temperature environment protection dispersing dye of the present invention has the advantages of high fastness of preparation products, high coloring power, brilliant color light, high level dyeing performance and high lifting performance. The low temperature environment protection dispersing dye can be used as a single color product and can also be matched with dispersing dye, such as 2BLN blue, 3B red, etc. The low temperature environment protection dispersing dye has optimal compatibility.
Description
(1) technical field
The present invention relates to a kind of low-temperature environment-friendly type dispersed dye, be specially adapted to the printing and dyeing of polyester material and vinegar fiber material.
(2) background technology
Polyester material and the dyeing of vinegar fiber material are a lot of with the type of Yellow disperse dye, wherein the usage quantity of C.I. DISPERSE YELLOW 23 (strong yellow RGFL) is bigger, but, classified as the forbidding dispersed dye by European Union member countries such as Germany because of it can cracking produce carcinogenic suspicious material or harmful aromatic amine under given conditions.Therefore, the kind that can effectively substitute this strong yellow RGFL is badly in need of seeking in each producer at present, and sodium yellow must be approaching with it, aspect of performance also needs similar with it simultaneously, as necessary low temperature modification, can form effective compatibleness with low temperature modification dyestuffs such as 2BLN indigo plant, 3B are red, in addition on the one hand must environmental protection, can satisfy the needs that dyeing textile product export.
Alternative C.I. DISPERSE YELLOW 23 effect better products of Chu Xianing in the market, most typical is that the SE-3R of Katyuan, Wenzhou leather company limited is golden yellow, but find through the use gradually of producer: SE-3R golden yellow with colorant match processes such as 2BLN indigo plant, 3B is red in compatibleness relatively poor,, overflow dyeing poor end to end as being prone in the dye gigging is prone to phenomenons such as a difference even look flower.So search out the product that can effectively substitute strong yellow RGFL, be still the difficult problem of pendulum in face of each printing and dyeing producer.
(3) summary of the invention
For the environmental issue that solves RGFL and with the compatibility problems of low temperature dyestuff, the invention provides a kind of low-temperature environment-friendly type dispersed dye.
Low-temperature environment-friendly type dispersed dye of the present invention, composed of the following components:
Weight fraction be 15～50% dye monomer A as chemical formula (I),
Weight fraction be 3～25% dye monomer B as chemical formula (II),
Surplus is an auxiliary agent.
Auxiliary agent described in the present invention comprises one of following or its mixture: naphthalene sulfonic acidformaldehyde condensation product, alkyl naphthalene sulfonic acid formaldehyde condensation products, sulfonated lignin.Described naphthalene sulfonic acidformaldehyde condensation product such as dispersing agent NNO; Alkyl naphthalene sulfonic acid formaldehyde condensation products such as Dispersant MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde), dispersing agent CNF (benzyl naphthalenesulfonate formaldehyde condensation compound) etc.; Sulfonated lignin such as sodium lignosulfonate (as commercial dispersants Reax 83A, Reax 85A) etc.
The weight fraction of above-mentioned dye monomer A is preferably 18～40%, and the weight fraction of dye monomer B is preferably 4～15%.The weight ratio of dye monomer A and dye monomer B is preferably 3～5: 1.
Low-temperature environment-friendly type dispersed dye of the present invention can prepare by the following method:
After dye monomer A, dye monomer B, auxiliary agent, water or the mixing of other wetting agent with the metering ratio, grind dispersion with shredder, then spraying drying.Above-mentioned dye monomer A can adopt the commercially available prod, as the C.I. DISPERSE YELLOW 54 former dyestuffs of Yabang Group Co, Jiangsu's production; Dye monomer B can adopt the commercially available prod, as the C.I. DISPERSE ORANGE 30 200 25 former dyestuffs of Zhejiang Province Longsheng Group Co., Ltd's production.
Low-temperature environment-friendly type dispersed dye of the present invention also can prepare by the following method:
With the metering C.I. DISPERSE YELLOW 54 (main ingredient is dye monomer A and auxiliary agent) of ratio and C.I. DISPERSE ORANGE 30 200 25 (main ingredient is dye monomer B and auxiliary agent), auxiliary agent add water piece together mix after, grind dispersion, then spraying drying; Also C.I. DISPERSE YELLOW 54, C.I. DISPERSE ORANGE 30 200 25 and auxiliary agent directly can be pieced together mixedly, be ground to and be uniformly dispersed.Above-mentioned C.I. DISPERSE YELLOW 54 and C.I. DISPERSE ORANGE 30 200 25 can adopt the commercially available prod, as the C.I. DISPERSE YELLOW 54 of Yabang Group Co, Jiangsu's production and the C.I. DISPERSE ORANGE 30 200 25 of Zhejiang Province Longsheng Group Co., Ltd's production.
Because dye monomer A, dye monomer B described in the present invention are the low temperature modification dyestuff, so dispersed dye of the present invention with low temperature modification dyestuff (2BLN indigo plant, 3B red) when matching, its compatibleness and consistency are all more satisfactory, can effectively substitute this product of strong yellow RGFL, also solve phenomenons such as golden yellow aberration end to end that is easy to generate of present SE-3R and look flower.
Low-temperature environment-friendly type dispersed dye preparation fastness excellent property of the present invention, tinting power height, coloured light is bright-coloured, has good level-dyeing property and enhancing, both can do monochromatic product use, also can carry out colorant match with dispersion dyestuffs such as 2BLN indigo plant, 3B are red, and compatibleness is splendid.
