Abstract
The invention provides a continuous high-whiteness whitening process for pure cotton fabric, which is characterized by comprising the following working procedures of: padding whitening agent solution, steaming, washing and drying, wherein the whitening agent solution selects a whitening agent with medium or higher medium affinity; placing the whitening agent solution into a groove, and ensuring that the pure cotton fabric passes through the groove, and has the pickup rate of between 50 and 80 percent; then making the pure cotton fabric enter a guide roller type steamer which is heated to be between 98 and 100 DEG C and is filled with saturated steam to be steamed for 55 to 65 seconds to ensure that the whitening agent has full color development; and then orderly performing washing at a temperature of 50 DEG C for 65 to75 seconds and neutralization in a neutralizing tank for 20 to30 seconds on the pure cotton fabric, performing washing on the pure cotton fabric at a temperature of 50 DEG C for 7 to 17 seconds, and then making the pure cotton fabric enter a drying cylinder at a temperature of between 90 and 120 DEG C to make a fabric cover dry. The process can effectively improve the whiteness of the pure cotton fabrics, and ensure that the soaping fastness of the whitened pure cotton fabrics is improved to more than level 4.
Description
Technical field
The invention provides a kind of continuous high-whiteness whitening process of pure cotton fabric, belong to technical field of textile printing.
Background technology
All cotton woven fabric is a native cellulose fibre, liked by the consumer.But because the whitening process of all-cotton fabric generally adopts low-affinity class brightening agents such as MST, BFA, on tentering, pad, dry and finish with bathing with softener, cause the whiteness of fabric lower, washable weak effect, can not satisfy the high and stable requirement of whiteness of high-grade fabric.Common process: the continous mode whitening process all is from stenter, adopts the low-affinity brightening agent to machine.Its technological process is simple, and whiteness is low, the characteristics of fastness to washing difference but exist, and can not satisfy the whiteness requirement of high-grade fabric.
Summary of the invention
The purpose of this invention is to provide a kind ofly the cotton fabrics whiteness can be brought up to a certain degree, washing fastness reaches more than 4 grades, and can make the continuous high-whiteness whitening process of the pure cotton fabric that woven fabric finishes under open width, continuous processing conditions.Its technical scheme is:
Comprise following operation: pad brightening agent solution, decatize, washing and oven dry, wherein brightening agent solution is selected the brightening agent of medium or medium higher affinity for use, brightening agent solution is put into groove, make pure cotton fabric process groove and have 50～80% pick-up, entered and be warmed up to 98～100 ℃, be full of in the guide roll type decatize case of steam decatize then 60 ± 5 seconds, make the abundant color development of brightening agent, then successively through 50 ℃ of washings 70 ± 5 seconds, closed 25 ± 5 seconds in the neutralization chamber, make the cloth cover drying through the drying cylinder that enters 90 ℃～120 ℃ after 50 ℃ of washings in 12 ± 5 seconds again.
The continuous high-whiteness whitening process of described pure cotton fabric, brightening agent adopts CB or the RSB or the Clariant PC of vapour crust, and the brightening agent solution concentration is not less than 3.5g/L.
The continuous high-whiteness whitening process of described pure cotton fabric, groove adopts the low liquid measure groove of multi roll, and volume is no more than 40 liters, and has automatic liquid level control.
The continuous high-whiteness whitening process of described pure cotton fabric, decatize operation are to carry out in being full of the decatize case of saturated vapor, so that the abundant color development of brightening agent, thereby reach high whiteness.
The continuous high-whiteness whitening process of described pure cotton fabric enters the COTTON FABRIC open width, and the speed of a motor vehicle is controlled at 50～60m/min, can realize continuity processing.
The continuous high-whiteness whitening process of described pure cotton fabric, 50 ℃ of rinsing bowl temperature, the temperature remains within the normal range for neutralization chamber.
The present invention compared with prior art has following advantage: can effectively improve the whiteness of pure cotton fabric, the soaping fastness of the pure cotton fabric after brightening is brought up to more than 4 grades.
