Problems solved by technology

[0002] During the dyeing and finishing process of cotton knitted fabrics, customers have higher and higher requirements for color accuracy, and the requirements for cylinder difference greatly exceed the industry standard 3-4 level allowable range. In addition to normal process control and quality control, dyeing and finishing plants , it is unavoidable that some fabrics have entered the drying and finalizing process after dyeing, and only found that the color tank is poor. It is very troublesome to go to the dyeing machine for such fabrics to repair. The color is not repaired, but the strength of the fabric and other quality indicators are damaged, causing major economic losses

Embodiment 1

[0102] Gray fabric specification: 300 grams of CVC brushed fleece

[0103] Fabric color: navy blue

[0104] Reason for repairing gray fabric: light color

[0105] Repair solution formula:

[0106] M-2GE Blue 0.6g / L

[0107] M-3BE red 0.45g / L

[0108] M-3RE yellow 0.22g / L

[0109] Penetrant 1g / L

[0110] Yuanming powder 10g / L

[0111] Soda ash 5g / L

[0112] When repairing the color, prepare the repair solution according to the above ratio, generally use a uniform small padding car, one dipping and one rolling the gray cloth rolling rate is 75%, the padding temperature is 30°C-40°C, and bake on the setting machine for 90 seconds. 150°C, then control the temperature at 50°C and wash with water for 10 minutes. Finally, after drying, napping, and setting, use the ORINTEX color measurement system for color matching. The color difference is 4-5 after testing. The washing fastness is tested according to GB / P3921-2008. The color fastness to cotton staining is grade 4, which is ...

Abstract

The invention relates to a method for the color retouching of a raw fabric, in particular to a method for the color retouching of cotton knitted fabric on a forming machine. The method is characterized by comprising the following processing steps: blending a retouching solution, preparing the raw fabric, padding the retouching solution, water scrubbing, drying, napping and forming. By using the method for the color retouching of the cotton knitted fabric, when the color cylinder difference is discovered after the cotton knitted fabric is dyed and enters the finishing procedure after the dryingand the forming, the cotton knitted fabric can be directly retouched on the forming machine; through analytic studies, reactive dyes such as M-2G blue, M-3BE red and M-3RE yellow for the padding areadopted as color retouching dyes; in order to increase the permeability of the raw fabric, a non-ionic penetrating agent is added into a padding solution, simultaneously the padding solution is addedwith anhydrous sodium sulfate and anhydrous sodium carbonate to ensure the water scrubbing chroma of the raw fabric after the color retouching, and the retouching solution can be prepared only according to the chroma; and the chroma can be adjusted to the normal quality standard through the treatments in the processing steps. The process method has the advantages of quick color retouching speed, good accuracy, no influence on other quality indexes of fabrics, cost saving and less discharge capacity.
