Abstract
The invention discloses a solution-discharge-free reduction method for polyester fibers. The solution-discharge-free reduction method for the polyester fibers specifically comprises steps as follows: (1) fabric preparation: performing inspection, fabric turning and end sewing on a polyester fiber fabric; (2) pretreatment: performing desizing treatment on the polyester fiber fabric; (3) dyeing: dyeing the fabric with disperse dye at the temperature of 135 DEG C, and keeping the temperature for 60 min; (4) fixation: reducing the temperature to 80 DEG C after dyeing, directly adding 1-3 g/L of acid reducing agent into a solution after dyeing without discharging the solution, and keeping the temperature for 30 min; (5) fabric spreading and shaping: shaping the fabric at the temperature of 170 DEG C and at the speed of 35-45 m/min; (6) packaging and storing in a storehouse. According to the method, the fabric with 100% polyester fibers is adopted, the production process is shortened with the solution-discharge-free reduction method, the vat occupying time is shortened, the cost is reduced, meanwhile, the pollution discharge is reduced, the color fastness can exceed the level 4, and the fabric is applicable to products such as sportswear, outdoor jackets and the like.
Description
Technical field
The present invention relates to dyeing field, specifically a kind of not discharge opeing of polyster fibre reducing process.
Background technology
Dyeing catch color, also deserves to be called look, refers to by chemical or other method and affect material itself and make it painted.By dyeing, can make object present the needed shades of colour of people, with colourful, decorate life.Textile material is processed with dye bath, makes dyestuff and fiber generation chemistry or physical chemistry combination, or on fiber, generates the technical process of insoluble coloring matter.Dyestuff should have the performances such as certain water-fastness, solarization, friction on fiber, and this performance is called dyefastness.
Dyeing course can be divided into three root phases.1. absorption: after fiber drops into dye bath, dyestuff is first diffused into fiber surface, then gradually transfers to fiber surface by solution, and this process is called absorption.As time goes on, the dye strength on fiber increases gradually, and dye strength in solution reduces gradually, through after a period of time, reaches poised state.Absorption inverse process be desorb, upper dye process in sorption and desorption be simultaneous.2. diffusion: the dyestuff that is adsorbed on fiber surface spreads to fibrous inside, until the dye strength of fiber each several part trend is consistent.Owing to being adsorbed on the dye strength of fiber surface and being greater than the dye strength of fibrous inside, impel dyestuff to be spread to fibrous inside by fiber surface.Now, the diffusion of dyestuff has destroyed the adsorption equilibrium of initial foundation, and the dyestuff in solution can constantly be adsorbed onto fiber surface again, and sorption and desorption reaches balance again.3. set: be the process that dyestuff is combined with fiber, different with fiber with dyestuff, its combination is also different.
In contemporary dye process, during to the fixation of fiber cloth, solution after dyeing in dye vat need be processed to rear discharge, in dye vat, put into again color-fixing agent and carry out fixation, after fixation, also need sewage to process, this process not only complicated, length expends time in, and strengthen and pollute, the cost of sewage disposal is increased, further raise the cost again, company is caused to certain pressure.
Summary of the invention
The object of the present invention is to provide not discharge opeing of the polyster fibre reducing process that a kind of time is short, COLOR FASTNESS is high, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
Not discharge opeing of a polyster fibre reducing process, specifically comprises the steps:
(1) join cloth: cloth, margin to seam are tested, turned over to polyster fibre fabric;
(2) pre-treatment: polyster fibre fabric is carried out to destarch processing;
(3) dyeing: utilize DISPERSE DYES to dye to fabric, temperature is 135 ℃, insulation 60min;
(4) fixation: be cooled to 80 ℃ after dyeing, not discharge opeing directly adds acidic reduction agent 1-3g/L in the solution after dyeing, insulation 30min;
(5) spread, sizing: in temperature, be under 170 ℃, the speed of a motor vehicle condition that is 35-45m/min, cloth to be shaped;
(6) packing warehouse-in.
As the further scheme of the present invention: the composition of polyster fibre fabric is 100% terylene.
As the further scheme of the present invention: in step (4), acidic reduction agent is 2g/L.
As the further scheme of the present invention: in step (5), the speed of a motor vehicle is 40m/min.
Compared with prior art, the invention has the beneficial effects as follows: adopt polyster fibre 100% fabric, through not discharge opeing reducing process, shortened production technology, reduce and account for the cylinder time, when reducing costs, reduced blowdown, more than COLOR FASTNESS can reach level Four.
