Description

Technical field:

[0001] The invention relates to a fiber material dyeing technology, in particular to a reactive dye denaturation bath dyeing technology. technical background:

[0002] Textile dyeing can be divided into one-bath dyeing and two-bath dyeing according to the nature of the dyeing bath. Generally speaking, the dyeing of pure textiles with a single component can be completed by using only one dye in one bath; for blended products, if the dyeing performance of each component is significantly different, it is necessary to use different types of dyes in different Two-bath dyeing is carried out under dyeing conditions. If the dyeing performance of each component is similar, it is possible to carry out one-bath dyeing under certain specific conditions. However, whether it is one-bath dyeing or two-bath dyeing, the common feature is that each dye bath keeps dyeing the dyed object during the dyeing process and the nature of the dye bath itself does not change fundamenta...
