Embodiment Construction

[0015] An ecological production method for wool blue cloth, including dyeing, after the cloth 1 is dyed in the dyeing tank 2, hangs through a plurality of rack devices 3, and at the same time blows and oxidizes the cloth on the rack with a blower 4 with air filtering function , the cloth on the hanger enters the dyeing tank for dyeing, and after being cycled to the required color depth (determine the number of cycles according to the required dyeing depth), the final product is blown, oxidized, dried, and stretched.

[0016] In each cycle, the time for the cloth to blow and oxidize on the hanger is 100 to 200 seconds. The weight ratio of the dye bath in the dye tank is: indigo dye: sodium hydrosulfite: caustic soda = 0.64-0.68: 0.59-0.63 In each cycle, the time for the cloth to be dyed in the dye tank is 20 to 30 seconds.

[0017] A kind of special equipment for the environment-friendly production method of woolen blue cloth, including a dyeing tank 2, and a hanger 3 for the c...

Abstract

The invention discloses a blue nankeen ecological production method and special equipment, wherein the method comprises the following steps: dyeing; hanging on a plurality of hanging racks after dyeing in a dye vat; blowing and oxidizing the cloth on the hanging racks by a blower with air filtration; dyeing the cloth on the hanging racks in the dye vat again; repeating the steps until the required color depth is achieved, blowing and oxidizing at the last time, and drying and tentering to obtain blue nankeen. The invention has simple process and short dyeing time, completes the whole dyeing procedure within 3-5h usually, and achieves the purpose of nearly zero sewage emission because dye liquor can be continuously used through replenishing dye materials, thereby being beneficial to the environment protection.

Description

Technical field: [0001] The invention relates to a production method and equipment for wool blue cloth. Background technique: [0002] In the existing production of wool blue cloth, after dyeing, it needs about 10 days of repeated exposure to the sun and repeated dyeing before the dyeing process can be completed. Invention content: [0003] The object of the present invention is to provide an environment-friendly production method and special equipment for wool blue cloth with short dyeing time and good environmental protection. [0004] Technical solution of the present invention is: [0005] An environment-friendly production method for wool blue cloth, including dyeing, characterized in that: after the cloth is dyed in a dyeing tank, it passes through a plurality of hangers, and at the same time uses a blower with an air filter device to uniformly blow and oxidize the cloth on the hangers , the cloth on the hanger enters the dyeing tank for repeated dyeing according t...
