Embodiment 1

[0023] Take 30g of disperse red dye and 200g of siloxane medium to prepare a dye solution for later use. Get 6kg of polyester fiber and put it into siloxane medium, liquor ratio 1:4.5, add dyeing solution and 500g ethyl acetate, keep 7 o C / min heating up to 80 o C, keep 2 o C / min heating up to 140 o C, keep warm for 60min, quickly cool down and remove the liquid, then add siloxane medium, with 7 o C / min heating up 80 o C to keep warm for 10 minutes, wash twice in total, and finally deliquify and dry to obtain the finished dyed product.

[0024]

Embodiment 2

[0026] Take 10g of disperse orange dye and 200g of siloxane medium to prepare a dye solution for later use. Take 1.5kg of polyester fiber and put it into siloxane medium, bath ratio 1:5, add dye solution and 50% ethanol, keep 5 o C / min heating up to 80 o C, keep 3 o C / min heating up to 140 o C, keep warm for 50min, quickly cool down and remove the liquid, then add siloxane medium, with 8 o C / min heating up to 90 o C to keep warm for 10 minutes, wash twice in total, and finally deliquify and dry to obtain the finished dyed product.

[0027]

Embodiment 3

[0029] Take 0.1g of disperse blue dye and 1g of siloxane medium to prepare a dye solution for later use. Take 10g of polyester fiber and put it into siloxane medium, the bath ratio is 1:10, add dyeing solution, keep 7 o C / min heating up to 80 o C insulation for 30min, the insulation process is divided into four equal parts, the first three parts are three times to add dye solution, the last part is to add 1g acetic acid, keep 2 o C / min heating up to 140 o C, keep warm for 60min, quickly cool down and remove the liquid, then add siloxane medium, with 7 o C / min heating up 80 o C to keep warm for 10 minutes, wash twice in total, and finally deliquify and dry to obtain the finished dyed product.

Abstract

The invention discloses a disperse dye polyster dyeing method using siloxane as a medium, and belongs to the technical field of textile dyeing and finishing. The method comprises the following steps of (1) adding materials to be dyed, a prepared dye solution and dye accelerators into the dye medium to be dyed; (2) performing liquid removal, siloxane medium washing and drying after the dyeing so asto obtain a dyeing finished product. Compared with a patent CN103074781A, the method provided by the invention has the advantages that ordinary materials to be dyed is not needed to be pre-treated; during the dyeing, only a small number of nontoxic and harmless dye accelerators need to be added; the dyeing of the polyster fabric under the condition of normal pressure or micro pressure is realized, so that the dependence and requirements (high temperature and high pressure) on the equipment are reduced. In the subsequent washing, a water washing method is avoided; the siloxane medium is used;the zero sewage discharge is reached; the dyeing uniformity and color firmness of the disperse dye dyeing can be effectively improved; the siloxane medium obtained through dyeing, washing and drying can be cyclically used through recovery; the ecological dyeing of the disperse dye is really realized.

Description

technical field [0001] The invention relates to a new polyester dyeing method with disperse dyes, especially polyester without any pretreatment, and during dyeing and washing in silicone medium, without using a large amount of water, dispersant and carrier, reducing the degree of pollution and realizing Zero discharge of sewage belongs to the technical field of textile ecological dyeing and finishing. Background technique [0002] Disperse dyeing is mainly for polyester and other synthetic fibers. The conventional dyeing of polyester fibers by disperse dyes at home and abroad is still water bath dyeing under the action of auxiliary agents, and the dyes are evenly dispersed in aqueous solution with the help of dispersants. In the actual dyeing process, a large amount of dispersant or carrier needs to be added. The carrier is toxic and will cause great harm to the environment and the human body. The solubilizing effect of the dispersant will cause more dyes to remain in the dy...
