During printing and dyeing of nylon cloth, problems of competitive dyeing, dyeing defects, color spots, color marks and the like may occur due to the problems of dye property difference, poor adaptability of equipment to dyes, improper setting of process parameters and the like, and printing and dyeing defects need to be repaired.
The traditional color repair process generally comprises the following steps: cloth preparation → stripping → secondary bleaching and dyeing → dehydration → drying in-process → sizing, namely the color of the abnormal cloth needs to be faded out (stripping), and then the required color is bleached and dyed again, the specific procedures include: cloth preparation: rewinding the abnormal cloth and distributing the abnormal cloth to a cloth vehicle; stripping: fading the color of the abnormal cloth; secondary bleaching and dyeing: re-coloring; dehydrating, drying, detecting and confirming bleaching and dyeing quality; and (6) shaping. Wherein, the secondary bleaching and dyeing process is the same as the bleaching and dyeing process, and the used reagents during stripping comprise the following components in percentage by mass: 1-3% of NaOH, 15-20% of peregal O and 5-8% of synthetic detergent, and sequentially adding the reagents into a stripping tank, wherein the bath ratio is 1: 25-30, the temperature is 98 ℃, and the stripping treatment is carried out for 20-30 min until all colors are faded; gradually cooling after stripping, washing with water, placing the cloth in 0.5ml/L acetic acid, treating at 30 deg.C for 10min, neutralizing residual alkali solution, and washing with clear water. In order to improve the color fastness of the cloth, the color fixing treatment can be carried out after the secondary bleaching and dyeing.
Although the traditional color repair process can achieve the repair treatment of abnormal grey cloth, the main defects exist: if the dyeing process is carried out for one time due to the errors of bleaching and dyeing, all colors are bleached out and then bleached and dyed again, so that the bleaching and dyeing working hours are prolonged, the treatment procedures and the use amount of chemical auxiliaries are increased, multiple times of bleaching and dyeing sewage can be generated, and the quality of cloth obtained by secondary bleaching and dyeing is not as good as that of initial bleaching and dyeing.
In the prior art related to the color correction of the cloth, a method for repairing the abnormal color mark of the nylon cloth after the color is patterned is not found. For example, the chinese patent application with the application number of "200910099745.7" entitled "method for fixing color of cotton knitted fabric on forming machine" discloses a method for fixing color of cotton knitted fabric on forming machine, which mainly comprises the following steps: preparing a repairing liquid, preparing grey cloth, padding the repairing liquid, baking by a setting machine, washing, drying, napping and setting, wherein the repairing liquid is mainly used for repairing colors of cotton knitted grey cloth; for example, the application number is '201610452953.0', the invention is named as a dyeing method for preventing cloth cover color spots, white spots and floating colors of light and thin fabrics, and the dyeing method is mainly used for preventing the light and thin fabrics from having color spots, white spots and floating colors, and provides a dyeing scheme capable of preventing the light and thin fabrics from having slight defects, and the scheme has an unsatisfactory prevention effect on fabrics with medium density or above or with large dyeing defects and is not suitable for repairing the color defects of nylon cloth.
