Dyeing technology

Abstract

The invention discloses a dyeing technology which specifically comprises the following steps: 1) mounting a primary color yarn and a transfer paper and starting a machine; 2) bending a high-temperature tape and the transfer paper toward a heating roller and keeping a certain distance by hydraulic devices at the two ends of the high-temperature tape; 3) heating the transfer paper and the primary color yarn by the high-temperature tape and the heating roller, heating and subliming the ink on the transfer paper and attaching to the primary color yarn and then recovering the dyed yarn by a yarn reel. According to the technology, the heated subliming dye is adopted for directly transferring on the yarn, the ink is automatically blended on a printer so that the yarn color can be realized; the color is accurate and repeated color change is not required; the color index is higher and can reach above level-4; the technology is simple and convenient in operation; the production efficiency is increased; the dyeing technology also can be directly used for dyeing the warp yarns in a textile machinery plant, can increase the economic benefit and can reduce resource waste and environmental pollution; one yarn can be dyed in different colors and different lengths according to the technology.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a dyeing process. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. As early as the Neolithic Age six or seven thousand years ago, our ancestors were able to use Hematite powder dyes the linen red. The primitive tribes living in the Nomuhong area of ​​the Qaidam Basin in Qinghai can dye the wool into yellow, red, brown, blue and other colors, and weave woolen cloth with color stripes. my country The printing and dyeing industry is also very developed.

Problems solved by technology

Yarn dyeing is a kind of printing and dyeing process. At present, yarn dyeing uses a large amount of water vapor and fuel, which has a bad impact on environmental protection. Traditional yarn dyeing uses a large amount of steam and fuel to incinerate to produce a large amount of air pollutants, which damages the environment. Fuel and injection A large amount of sewage is produced by rinsing several times with water, and the sewage must be treated by sewage, which wastes a lot of resources, land and facilities
