Embodiment 1

[0061] A color-fixing method for screen printing natural fiber fabrics with reactive dyes, the grammage output by screen printing equipment is >200g / m 2 The reactive dye screen printing printed cotton fabric is the color fixing object, and the wet pile fixing method is adopted, and the following steps are followed in turn:

[0062] a, screen printing fabrics for the front side of the reactive dyes, lining the isolation chemical fiber fabric polyester cloth, and the cloth heads of the two are wound together on the wet stack winding roller;

[0063] b. The screen printing cloth on the front side of the fabric reactive dye is directly output by the screen printing equipment and moves in open width, and enters the wet stack production unit together with the isolated chemical fiber fabric polyester cloth. Coil into a shaft. Then the winding roller is separated from its driving motor, and then the winding roller full of the fabric is transported to the wet stacking area through the...

Embodiment 2

[0066] A color-fixing method for screen-printed natural fiber fabrics with reactive dyes, the weight of which is downloaded and output by screen-printing equipment is 2 The reactive dye screen printing silk fabric is the color fixing object, and the wet pile fixing method is adopted; in its processing steps, except for the winding line speed of the winding roller described in the b step, the line moving with the open width of the screen printing fabric The ratio of speed is 1: 1.05, and the wet stacking time described in step b is 15 hours, others are all the same as embodiment one.

Embodiment 3

[0067] Embodiment three, please refer to the attached image 3 .

[0068] A kind of equipment that is used for described fabric color fixing method, comprises a wet stack winding roller 3; The wet stack winding roller 3 can be supported on the A frame and can rotate; A motor 8; The motor 8 can be connected with The wet stack winding roller 3 is coaxially quickly assembled and disassembled; a frequency converter 7; the frequency converter 7 is electrically connected to the motor 8; a PLC controller 16; the PLC controller 16 is electrically connected to the frequency converter 7; 21; a pair of cloth guide rollers 20, 21 are arranged on the cloth feeding side of the wet stack winding roller 3, and a distance is kept between the two; thereby making the fabric form a vertical loop 17 in its open-width movement; a photoelectric control Device pair G; the light source 18 and the photoelectric sensor 19 of the photoelectric controller pair G are respectively arranged under a pair of ...

Abstract

The invention discloses a fixation method and fixation equipment for screen printing of natural fiber fabrics by reactive dye. The fixation method is mainly characterized in that: the fixation method adopts constant linear speed and low and even tension of a humid heap wind-up roll for winding, and adopts statistic humid heap fixation; the fixation equipment is mainly characterized in that: the fixation equipment comprises the humid heap wind-up roll, a motor coaxially connected with a wind-up roll shaft, a frequency convertor electrically connected with the motor, a controller electrically connected with the frequency convertor, a pair of cloth guide rollers, a spreading roll, a photoelectric controller pair and a constant linear speed tension controller which are connected with the controller through electric signals, a constant linear speed tension control device separating chemical blended fabrics, and a second spreading roll; and the constant linear speed tension controller is the tension controller according with a winding machinery characteristic curve mu K=f(D). The fixation method has the characteristics of short process flow, no occurrence of color paste adhesion, color overlapping contamination and pattern distortion, energy conservation, consumption reduction and emission reduction, and the like; and the equipment has the characteristics of reasonable structure, low preparation cost, good quality of finished products printed cloth, and the like. The invention initiates a novel method for the screen printing of the natural fiber fabrics by the reactive dye.

Description

technical field [0001] The invention relates to a color-fixing method and equipment for reactive dye screen printing natural fiber fabrics, belonging to the natural fiber fabric printing technology. Background technique [0002] The printing process of the natural fiber fabric of prior art is reactive dye one-phase method printing process, and its technological process is: [0003] Pretreatment of semi-finished products (grain cloth)—reactive dyes (including alkali and urea, etc.) in the same paste printing (plate screen printing or cylinder screen printing)—drying—steaming and color fixing (102°C, 7~8min)—— Soaping - drying - to get printed fabrics. [0004] This traditional printing process not only has a long process, but also requires a large investment in equipment, high energy consumption, and a large amount of sewage (waste gas, waste water). Then, how to reform this traditional process and provide a new process of reactive dye screen printing for natural fiber fabr...
