Abstract
The invention discloses a dyeing method for a deep color polyester-cotton fabric. According to the method, a traditional dyeing process comprising preparation of polyester-cotton fabric semi-finished product, dispersing for bottoming, baking, reduction clearing, wrinkle pulling, obtaining activity through a padding machine and steam washing is improved to be the processes of preparation of the polyester-cotton fabric semi-finished product, dispersing for bottoming, baking, obtaining activity through a cold dyeing machine, stacking and water washing, so as to improve the traditional dyeing process. The dyeing process is as follows: after padding and dye solution dispersing are performed on the polyester-cotton fabric semi-finished product and baking is performed, the traditional procedures of reduction clearing, wrinkle pulling and steam washing are eliminated, after the cold dyeing machine is selected for padding reactive dye and an alkaline agent, coiling and thermal insulation stacking are performed on the fabric so as to enable the reactive dye to dye, and under the effect of the alkaline agent, the purpose of reduction and clearing of disperse dye can be achieved through water washing. The dyeing method provided by the invention can be used for performing deep concentration coloring on the T/C fabric, so that the product quality can be stabilized, and a remarkable effect on energy conservation and emission reduction is realized.
Description
Technical field
The present invention relates to dark T/C(polyester-cotton blend) dyeing of fabric dispersed activity dyestuff, belong to dyeing and printing process field.
Background technology
In the dyeing processing of dark T/C fabric, conventionally use padding machine pad dyeing method to dye to fabric, fabric disperses dye liquor to dry, bake by padding, first make to dye in the polyster fibre component of fabric, through the loose colour on reduction cleaning removal fabric face and the staining on cotton fiber, then through pulling off son, then pad REACTIVE DYES, oven dry by padding machine again, rinsing machine vapour steaming colour fixing makes to dye cotton fiber in REACTIVE DYES, finally water-wash away on fabric face loose colour and dry.This technological process is long: dispersion bottoming → bake → reduction cleaning → pull off the washing of son → bottoming mantle activity → decatize, recruitment is many, is unfavorable for production operation, easily because of Steam pressure control shakiness, causes the faults such as water spot, aberration.Operation is many, need to carry out reduction cleaning, pull off son, decatize, causes the consumption for the energy sources amount large, and adjuvant used kind and quantity are many, as sodium hydrosulfite, salt, caustic soda, soda ash etc., very unfavorable to energy-saving and emission-reduction.The adjuvant used contrast of traditional handicraft and new technology is as shown in table 1.
Therefore, the inventor considers, conventional process flow " T/C fabric semi-finished product → dispersion bottoming → bake → reduction cleaning → pull off son → bottoming mantle activity → decatize to wash " is improved to " T/C fabric semi-finished product → dispersion bottoming → bake → cold dyeing mantle activity → bank up → wash ", , save the reduction cleaning of traditional handicraft, pull off son and decatize operation, after selecting cold dyeing machine to pad REACTIVE DYES and alkaline agent, clot insulation is banked up, make to dye in REACTIVE DYES, under the effect of alkaline agent, by washing, realize DISPERSE DYES reduction cleaning simultaneously, thereby shortened process, reduce the consumption of the energy, reducing auxiliary agent uses, reach the object of energy-saving and emission-reduction.
Summary of the invention
The technical problem that the present invention solves is, a kind of colouring method of dark T/C fabric is provided, and uses the method to dye and can reach the quality requirement of finished product textiles, and shortening flow process, the energy consumption that reduces, minimizing auxiliary agent are used, thereby reaches the object of energy-saving and emission-reduction.Traditional technological process is: T/C fabric semi-finished product → dispersion bottoming → bake → reduction cleaning → pull off son → bottoming mantle activity → decatize to wash.
In order to solve above technical problem, the invention provides a kind of colouring method of dark T/C fabric, comprise: the process of described dyeing is: T/C fabric semi-finished product are padded to DISPERSE DYES through padding machine and dry, bake, save traditional handicraft reduction cleaning, pull off son and decatize operation, after selecting cold dyeing machine to pad REACTIVE DYES and alkaline agent, clot insulation is banked up, make to dye in REACTIVE DYES, under the effect of alkaline agent, by washing, reach the object to DISPERSE DYES reduction cleaning simultaneously.New technological flow is: T/C fabric semi-finished product → dispersion bottoming → bake → cold dyeing mantle activity → bank up → wash.
Preferably, padding machine pads the DISPERSE DYES speed of a motor vehicle 40 ± 1m/min, car pick-up 65 ± 3%, padding machine pressure be adjusted to left 0.219MPa, in 0.19 MPa, right 0.19 MPa.
Preferably, the baker speed of a motor vehicle 40 ± 1m/min, 195 ± 2 ℃ of preliminary drying temperature, 200 ± 1 ℃ of baking temperatures
Preferably, described colouring method, save traditional handicraft reduction cleaning, pull off son and decatize operation, select cold dyeing machine to pad REACTIVE DYES and alkaline agent after clot insulation bank up, make to dye in REACTIVE DYES, under the effect of alkaline agent, by washing, reach the object to DISPERSE DYES reduction cleaning simultaneously
Preferably, described fabric dyeed and is specially:
(1) cold dyeing locomotive speed 40 ± 1m/min, car pick-up 65 ± 3%, padding machine pressure be adjusted to left 0.23MPa, in 0.18 MPa, right 0.23 MPa.Clot is initiatively rolling of low-tension, clot tension force 0.1MPa.
(2) the temperature 20-30 ℃ of 10-12 hour that banks up.
Preferably, the process of described washing is: by the first cold wash (30 ± 5 ℃) of the fabric after dyeing, after soap (95 ± 2 ℃), then hot water wash (80-85 ℃), cold wash, oven dry.
Preferably, described alkaline agent concentration is 23g/L ~ 34 g/L.
Preferably, the concentration of soaping agent in liquid of soaping described in is 2.8g/L.
Preferably, described soaping agent is neutral soap lotion.
Preferably, the temperature of described oven dry is 110 ℃ ~ 120 ℃.
The specific embodiment
In order further to understand the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these are described is for further illustrating the features and advantages of the present invention, rather than limiting to the claimed invention.
The colouring method that the embodiment of the invention discloses a kind of dark T/C fabric, comprising:
A, use operation well known to those skilled in the art;
B, with dyestuff well known to those skilled in the art, auxiliary agent.
Flow process as designed in the present invention, the process of described dyeing is:
T/C fabric semi-finished product are padded to DISPERSE DYES through padding machine to be dried, bakes, save traditional handicraft reduction cleaning, pull off son and decatize operation, after selecting cold dyeing machine to pad REACTIVE DYES and alkaline agent, clot insulation is banked up, make to dye in REACTIVE DYES, under the effect of alkaline agent, by washing, reach the object to DISPERSE DYES reduction cleaning simultaneously.
