In textile processing, stripping is a color removal technique employed to partially or eliminate color from dyed textile materials. Textile dyeing industries often face challenges like uneven or flawed dyeing and the appearance of color patches on the fabric's surface during the dyeing process and subsequent textile material processing stages.
Industrial dye degradation is any of a number of processed by which dyes are broken down, ideally into innocuous products. [1] Many dyes, specifically in the textile industry such as methylene blue or methyl red, are released into ecosystems through water waste. [2] Many of these dyes can be carcinogenic.
Textile dyeing plants generate wastewater that contain synthetic (e.g., reactive dyes, acid dyes, basic dyes, disperse dyes, vat dyes, sulphur dyes, mordant dyes, direct dyes, ingrain dyes, solvent dyes, pigment dyes) [40] and natural dyestuff, gum thickener (guar) and various wetting agents, pH buffers and dye retardants or accelerators.
Skein, package, beam, and space dyeing methods are used to dye yarns. In skein dyeing the yarns are loosely wound into hanks or skein and then dyed. The yarns have good dye penetration, but the process is slow and comparatively more expensive. In package dyeing yarns that have been wound on perforated spools are dyed in a pressurized tank.
The textile bleaching (or bleaching of textiles) is one of the steps in the textile manufacturing process. The objective of bleaching is to remove the natural color for the following steps such as dyeing or printing or to achieve full white. [1] All raw textile materials, when they are in natural form, are known as 'greige' material. They have ...
Textile manufacturing or textile engineering is a major industry. It is largely based on the conversion of fibre into yarn , then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing , household items, upholstery and various industrial products.
Textile recycling is the process of recovering fiber, yarn, or fabric and reprocessing the material into new, useful products. [1] Textile waste is split into pre-consumer and post-consumer waste and is sorted into five different categories derived from a pyramid model.
Scouring is an essential pre-treatment for the subsequent finishing stages that include bleaching, dyeing, and printing. [5] Raw and unfinished textiles contain a significant amount of impurities, both natural and foreign. It is necessary to eliminate these impurities to make the products ready for later steps in textile manufacturing. [6]
