Description
Technical Field
The invention relates to a polyester cotton dark colored fabric disperse/reactive dye one-bath dyeing process, and belongs to the technical field of textile printing and dyeing.
Background
With the rapid development of science and technology, the human living standard is continuously improved, and especially the ecological environment protection is paid unprecedented attention. In the printing and dyeing industry, the pollution to the environment is reduced through water and energy conservation, consumption reduction and emission reduction, and the method becomes urgent for each enterprise.
The existing polyester cotton dark colored fabric is dyed by adopting an active/disperse two-bath method, and the dyeing technology has the advantages of long process flow, low production efficiency, high energy consumption of water, electricity, steam and the like and high production cost. Under the form of advocating energy saving, emission reduction and green manufacturing at present, research polyester cotton one-bath dyeing realizes the short-flow continuous dyeing processing of polyester cotton fabric, and has important significance for reducing the cost of polyester cotton dyeing orders, improving the production efficiency and leading to the market.
In recent years, many printing and dyeing enterprises try a polyester-cotton one-bath dyeing method of deep-color polyester-cotton fabric to replace a polyester-cotton two-bath dyeing method, but the problems of low dyeing fastness, low fabric color yield and the like of the polyester-cotton one-bath dyeing method are abandoned because the dyeing fastness of the polyester-cotton one-bath dyeing method is not required.
The patent CN101392462A discloses a polyester cotton fabric dispersing and reactive dye one-bath extra-deep dyeing process, which comprises the steps of selecting WW series disperse dye and C series reactive dye, immersing pure cotton fabric in dye liquor once, rolling once by a padder, pre-drying after rolling, baking after pre-drying, steaming in a steaming box, washing with water, soaping after washing with water, and drying to finish dyeing. The dyeing process has certain limitations on the specific dye used.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a polyester cotton dark colored fabric dispersion/reactive dye one-bath dyeing process which is scientific and reasonable in design, simple in process flow, stable in production, and high in dyeing fastness and depth, and the production cost of polyester cotton dyed fabrics is effectively reduced.
The invention relates to a preparation method of polyester cotton dark colored fabric disperse/reactive dye one-bath dyeing process, which specifically comprises the following steps:
padding the processed and pretreated fabric with dye liquor, drying, high-temperature baking, padding the dye liquor, steaming, cleaning with clean water, cleaning with a reductive cleaner, soaping and drying.
When cleaning with a reductive cleaner, the solution composition is preferably: reductive cleaner GIN: 8-10 g/L, naOH: 2.5-3.5 g/L, and the balance of water.
The reductive cleaner GIN is a liquid reductive cleaner which is free of sulfur, environment-friendly and has a dispersing function.
When the cleaning agent is used for cleaning, the pH value of the solution is preferably 8-9, and the temperature of the water washing tank is preferably 90-95 ℃.
The soaping solution for high-temperature soaping during active fixation is preferably: soaping agent Isopon RSS Liq NEW: 2-3 g/L, and the balance of water.
The soaping agent Isopon RSS Liq NEW is a high-concentration dispersing anti-sticking agent soaping agent.
Among these, preferred materials are as follows:
the reducing cleaning agent REDULIT GIN is commercially available from Shanghai Jia and chemical Co.
The soaping agent Isopon RSS Liq NEW is a product sold by Tianjin Hongliyuan industry and trade company Limited.
Compared with the prior art, the invention has the following beneficial effects:
(1) According to the invention, a vat cleaning agent GIN and NaOH are added into a water washing tank during active fixation, and under the conditions that the pH value of a solution is 8-9 and the temperature is 90-95 ℃, the redox potential generated by the vat cleaning agent GIN is enough to destroy most of disperse dyes, but not enough to destroy many reactive dyes, and under the strong dispersion capability, after the unfixed disperse dyes adsorbed on the surface of the fiber are destroyed, degradation products of the unfixed disperse dyes are well dispersed in a treatment bath and are not stained back on the cloth surface, so that the fabric obtains better fastness;
(2) The soaping with active fixation adopts the high-concentration dispersion anti-staining soaping agent, so that unfixed dye can be effectively removed, and even if a part of salts used in dyeing still remain, the floating color can be effectively removed, so that the fastness of the fabric is further improved;
(3) The invention omits two processes of pad drying dyeing and dispersion fixation, greatly reduces the discharge of waste water, and realizes the purposes of energy conservation, emission reduction, environmental protection and consumption reduction.
