During the dyeing process, the dye must become close and even with the material in order to produce a uniform color that is fast to moisture, heat, and light. [5] Due to their superior fastness properties and simple application, reactive dyes are currently the most common type of dye for cotton dyeing. [6] The CPB technique uses less water and ...
Batch dyeing (exhaust dyeing) is a method of dyeing a textile material. The method involves the gradual transfer of dye from a dye bath to the textile material in the same piece of equipment. [1] The various methods of batch dyeing result from the type of machine used in the dyeing process.
This technique of dyeing is unique, in that the final color is controlled by the choice of the diazoic and coupling components. This method of dyeing cotton is declining in importance due to the toxic nature of the chemicals used. Sulfur dyes are two-part "developed" dyes used to dye cotton with dark colors. The initial bath imparts a yellow or ...
Cotton is shipped to mills in large 500-pound bales. When the cotton comes out of a bale, it is all packed together and still contains vegetable matter. The bale is broken open using a machine with large spikes, called an opener. To fluff up the cotton and remove the vegetable matter, the cotton is sent through a picker or a similar machine.
Cotton is an absorbent fibre which responds readily to colouration processes. Dyeing is commonly carried out with an anionic direct dye by completely immersing the fabric (or yarn) in an aqueous dyebath according to a prescribed procedure. For improved fastness to washing, rubbing, and light, other dyes such as vats and reactives are commonly ...
The process is called dyeing. dye lot The dye lot is a number that identifies yarns dyed in the same vat at the same time. Subtle differences can appear between different batches of the same color yarn from the same manufacturer.
The common dyeing process of cotton yarn with reactive dyes at package form is as follows: The raw yarn is wound on a spring tube to achieve a package suitable for dye penetration. These softened packages are loaded on a dyeing carrier's spindle one on another. The packages are pressed up to a desired height to achieve suitable density of packing.
