Abstract

Belonging to the technical field of dyed umbrella cover cloth manufacturing, the invention discloses a short-flow preparation method for a padder dyed umbrella cover cloth. The method includes the steps of: a) umbrella cover cloth pretreatment: soaking an umbrella cover cloth in a strong alkali solution and performing washing to obtain pretreated umbrella cover cloth; b) dyeing liquor preparation:mixing an alkali liquid with a dye solution to obtain dye liquor; c) padding the pretreated umbrella cover cloth in the dye liquor to obtain dyed umbrella cover cloth; d) baking and color fixing: baking the padded umbrella cover cloth to obtain baked umbrella cover cloth; and 3) washing. The method provided by the invention is suitable for all medium color and light color systems, and can reduce50-60% of dye vat dyeing production, and the color accuracy can reach 99% or more. The method provided by the invention can reduce sewage discharge and energy consumption on the basis of guaranteeingthe existing product quality, and achieves the goal of energy saving and emission reduction. The umbrella cover cloth prepared by the method provided by the invention has the characteristics of high color saturation, good color fastness, etc.

Description

technical field [0001] The invention relates to the technical field of manufacturing dyed canopy cloth, in particular to a preparation method of dyed canopy cloth by a short-process pad car. Background technique [0002] High temperature and high pressure jigger dyeing and overflow dyeing are currently the most important dyeing methods in the polyester canopy market, which can not only obtain satisfactory color saturation, but also perfectly reflect the color fastness and shade of the dye. [0003] The company's current normal dyeing production accounts for about 55-60%, and the monthly output is roughly 21-23 million meters. Although the traditional high-temperature, high-pressure jigger dyeing and overflow dyeing are simple to operate, they also have certain defects: high energy consumption, low output, high cost, and large amount of sewage, which seriously affect the development prospects of printing and dyeing enterprises. Contents of the invention [0004] In order t...
