Technical Field
The invention relates to a disperse/reactive dye one-bath dyeing process for polyester-cotton dark fabric, belonging to the technical field of textile printing and dyeing.
Background
With the rapid development of science and technology, the living standard of human beings 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 by saving water and energy, reducing consumption and emission, and the method becomes a priority of various enterprises.
The existing polyester-cotton deep-color fabric is dyed by an active/disperse two-bath method, and the dyeing technology has the advantages of long process flow, low production efficiency, large energy consumption of water, electricity, steam and the like and high production cost. Under the current mode of advocating energy saving and emission reduction and green manufacturing, the short-flow continuous dyeing processing of the polyester-cotton fabric is realized by researching polyester-cotton one-bath dyeing, and the method has important significance for reducing the order cost of polyester-cotton dyeing, improving the production efficiency and leading the market.
In recent years, many printing and dyeing enterprises try to replace a two-bath dyeing method of polyester and cotton by a one-bath dyeing method of polyester and cotton fabric with dark color, but the problems that the dyeing fastness of the polyester and cotton one-bath dyeing method cannot meet the requirement, the color yield of the fabric is low and the like cannot be effectively solved, and the method is abandoned.
Patent CN101392462A discloses a process for dyeing polyester-cotton fabric with disperse and reactive dyes in a very deep bath, which selects WW series disperse dyes and C series reactive dyes, puts pure cotton fabric into dye liquor to dip once, then rolls once with padder, rolls, pre-dries, dries after pre-dries, then steams in a steaming box, washes after steaming, washes with water, washes with soap after washing, washes with water, dries, and finishes dyeing. The dyeing process has certain limitation on the specific dye used.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a disperse/reactive dye one-bath dyeing process for polyester-cotton dark fabric, which has the advantages of scientific and reasonable design, simple process flow, stable production, effective reduction of the production cost of the polyester-cotton dyed fabric and high dyeing fastness and depth.
The preparation method of the polyester-cotton deep color fabric disperse/reactive dye one-bath dyeing process specifically comprises the following steps:
padding the fabric which is processed and pretreated with dye liquor → drying → high-temperature baking → padding color fixing liquor → steaming → washing with clear water → washing with reducing detergent → soaping → drying.
When cleaning with a reducing cleaner, the solution composition is preferably: reducing the cleaning agent GIN: 8-10 g/L, NaOH: 2.5-3.5 g/L, and the balance of water.
The reducing cleaning agent GIN is a liquid reducing cleaning agent which does not contain sulfur, is environment-friendly and has a dispersing function.
When the reducing cleaning agent is used for cleaning, preferably, the pH value of the solution is 8-9, and the temperature of the rinsing bath is 90-95 ℃.
The preferred soaping solution in the high-temperature soaping in the active color fixation is as follows: soaping agent Isopon RSS Liq NEW: 2-3 g/L, and the balance of water.
The soaping agent Isopon RSS Liq NEW used is a high-concentration dispersion anti-staining agent soaping agent.
Among them, preferred materials are as follows:
the reducing cleaning agent REDULIT GIN, a commercially available product of Shanghai Jia and chemical Co.
The soaping agent Isopon RSS Liq NEW is a product sold by Hongyuan industrial and trade company Limited in Tianjin city.
Compared with the prior art, the invention has the following beneficial effects:
(1) according to the method, a reducing cleaning agent GIN and NaOH are added into a washing tank during active color fixation, under the conditions that the pH value of a solution is 8-9 and the temperature is 90-95 ℃, the oxidation-reduction potential generated by the reducing cleaning agent GIN is enough to destroy most disperse dyes but not enough to destroy many active dyes, and under the strong dispersing capacity of the reducing cleaning agent GIN, after unfixed disperse dyes adsorbed on the surface of a fiber are destroyed, degradation products of the unfixed disperse dyes are well dispersed in a treatment bath and cannot be back-stained on a cloth cover, so that the fabric obtains better fastness;
(2) according to the soaping method for active color fixation, the high-concentration dispersion anti-staining soaping agent is adopted, unfixed dye can be effectively removed, and loose color can be effectively removed even if part of salts used in dyeing are still remained, so that the fastness of the fabric is further improved;
(3) the invention omits two processes of rolling dry dyeing and disperse color fixation, greatly reduces the discharge of waste water, and realizes the purposes of energy conservation, emission reduction, environmental protection and consumption reduction.
