Grey fabric dirt removing method used in terylene bags and suitcases light color/bright color dyeing

Abstract

The invention relates to a grey fabric dirt removing method used in terylene bags and suitcases light color / bright color dyeing. The grey fabric dirt removing method used in terylene bags and suitcases light color / bright color dyeing comprises following steps: 1, 3g / L of an oil removing agent and 3g / L of caustic soda are introduced into a desizing water-washing combined trough, the temperature isincreased to 100 DEG C, and grey fabric full width is introduced into the desizing water-washing combined trough for wetting, thermal expansion, and emulsification; and 2, three times of hot water rolling washing and one time of cold water rolling washing are carried out. The treatment time is short; speed is fast; dirt and oil spots can be removed completely; dyeing finished products obtained viatreatment possesses following advantages: the cloth surface is more flat, and the color is more bright.

Description

technical field [0001] The invention relates to a process for removing dirt from gray cloth, in particular to a process for removing dirt from gray cloth for polyester luggage. Background technique [0002] During the printing and dyeing process, the gray cloth often has dirt and oil spots, etc. If these dirt and oil spots are not removed during the dyeing process, it will seriously affect the quality of the product. Enterprises have brought great losses. At present, most printing and dyeing enterprises use degreaser and caustic soda alone for high-temperature pre-treatment. After 50 minutes of heat preservation at 130°C in the dyeing vat, the dirt can be removed, and hot water and cold water are also used. Wash the lye on the cloth surface, and then dye it, which will consume a lot of production costs such as water, electricity, steam, etc., and the processing time is long, and it is difficult to improve the economic benefits of the enterprise. If the degreasing agent, caus...

If the degreasing agent, caustic soda and The dye is dyed together in the same bath. Because the dye is not resistant to alkali, it will cause discoloration, and the one-bath method cannot be used. If no caustic soda is added, only the degreasing agent and the dye are added in one bath. The decontamination effect is not good, and the cloth surface remains 50% stain present
