Abstract
The invention discloses a dyeing and finishing process of polyester fabrics. The dyeing and finishing process comprises the following steps: (a) desizing, namely dipping and rolling the fabrics in desizing liquid, and adding 4-6g of oxidized desizing liquid, 2-3g of chelating dispersant and 300-310g of liquid caustic soda into the desizing liquid per gram; (b) dyeing, namely preparing dyeing liquid according to the bathing ratio of 1:8, firstly adding water at the temperature 40 DEG C, then adding dispersed dyestuff, a dye leveling agent and a buffering agent into the water, heating the dyeing liquid to 130 DEG C at the heating speed of 1.5-2 DEG C/min, then performing heat preservation, dipping the fabrics for 50 minutes, then cooling the dyeing liquid to 70-80 DEG C, then performing heat preservation, adding an acid reducing agent, and dipping and dyeing the fabrics for 20 minutes; and (c) soaping, namely conveying the fabrics into a soaping box by a conveying belt, and carrying out dynamic showering by circulation of soaping liquid. The dyeing and finishing process disclosed by the invention has the advantages that oil stains on the fabrics can be removed with high efficiency, so that the energy-saving and timing-saving effects are achieved.
Description
Technical field
The present invention relates to a kind of dyeing and finishing technology of polyester textile.
Technical background
When taking yarn as the destarch pre-treatment in dyeing and finishing technology of the polyester textile of warp, be present in efflorescence slurry concentration in auxiliary agent groove very high, these chemical sizwes are all high molecular polymers, and its viscosity is high, easily condense, and easily cause the anti-phenomenon of being stained with cloth cover of slurry.On the other hand, spinning oil is when destarch process, and the oil assistant that removes of interpolation usually well can not soak the greasy dirt on fabric, permeates, as flower, dispersion, solubilising, the effect of washing lamp, finish and greasy dirt removed from fiber and fabric.Traditional dyeing and finishing technology needs to remove impurity by refining procedure, and processing step is numerous and diverse, during consumption energy consumption.
Summary of the invention
The technical problem that the present invention solves provides a kind of dyeing and finishing technology of polyester textile, can remove the greasy dirt on fabric more efficiently, energy-and time-economizing more.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of dyeing and finishing technology of polyester textile, comprises the following steps:
A, destarch: textile pad desizing liquid, desizing liquid adds 4 ~ 6g/L and is oxidized desizing liquid, 2 ~ 3g/L chelated dispersants, 300 ~ 310g/L liquid caustic soda;
B, dyeing: be that 1:8 configures dye liquor with bath raio, first add 40 DEG C of water, then in water, DISPERSE DYES, dye leveller and buffer is added, be incubated after dye liquor being heated to 130 DEG C with the programming rate of 1.5 ~ 2 DEG C/min, contaminate fabric 50min, then dye liquor is cooled to 70 ~ 80 DEG C of insulations, adds acidic reduction agent and contaminate fabric 20min;
C, to soap: fabric is delivered to by conveyer belt and soaps in case, carry out dynamic shower by circulation soap lye.
Preferably, in described step a, the temperature of desizing liquid is 95 DEG C, and fabric is 80m/min by the speed of desizing liquid.
Preferably, the dye leveller in described step b is that dimethylethanolamine and ethoxylated lanolin mix with the ratio of 4:1.
The present invention is after fabric carries out destarch, directly dyeing, by adding DISPERSE DYES, dye leveller and buffer in dye liquor, improve the ability of emulsification and dispersed paste, eliminate the refinement step in traditional dyeing and finishing technology, decrease process time and energy resource consumption.
Detailed description of the invention
The dyeing and finishing technology of a kind of polyester textile of the present invention, comprises the following steps:
A, destarch: textile pad desizing liquid, desizing liquid adds 4 ~ 6g/L and is oxidized desizing liquid, 2 ~ 3g/L chelated dispersants, 300 ~ 310g/L liquid caustic soda;
B, dyeing: be that 1:8 configures dye liquor with bath raio, first add 40 DEG C of water, then in water, DISPERSE DYES, dye leveller and buffer is added, be incubated after dye liquor being heated to 130 DEG C with the programming rate of 1.5 ~ 2 DEG C/min, contaminate fabric 50min, then dye liquor is cooled to 70 ~ 80 DEG C of insulations, adds acidic reduction agent and contaminate fabric 20min;
C, to soap: fabric is delivered to by conveyer belt and soaps in case, carry out dynamic shower by circulation soap lye.
Wherein, in step a, the temperature of desizing liquid is 95 DEG C, and fabric is 80m/min by the speed of desizing liquid.Dye leveller in step b is that dimethylethanolamine and ethoxylated lanolin mix with the ratio of 4:1, buffer be NH3H2O and NH4Cl configuration cushioning liquid in order to regulate dye liquor pH value, acidic reduction agent is stannous chloride solution.
Claims (3)
