Higher substantivity for cellulose. Dye at 45-50 °C with more caustic soda and less salt (none for mercerised cotton or regenerated cellulosic fibres). 

Table 7.1 Important reactive systems for cellulosic dyeing...

In contrast to cellulosic dyeing with reactive dyes, the fibroin-dye bonds are remarkably stable in aqueous media of pH 4 to 10 [117]. Since there exists only a negligible amount of bond hydrolysis even at high temperature and in a medium of pH 2, the cleavage of the fibroin-dye bond is not a problem in reactive-dyed silk. The stability of these bonds when dyeing with difluoropyrimidine dyes is the highest in both acidic and basic media [118]. 

Adjustment of pH by neutralization. Cellulose dyeing and finishing companies mainly release alkaline baths, which can be neutralized by introduction of C02-containing waste gas from the power/steam generation plant [76].

Natural gum antimigrant for continuous dyeing of cotton and polyester/cotton with disperse and cellulosic dyes. 

Fixative for acid dyes on nylon or wool. Very low free phenol/formaldehyde content. Effective reserve for direct dyes in nylon/cellulosic dyeing.

A 53-year-old man with severe panc5rtopenia and splenomegaly and a history of pain during urination and hematuria for 2 years was found to have increased bladder wall thickness and massive splenomegaly, which was attributed to bladder cancer with splenic metastases [33 ]. He had been exposed to an unspecified cellulosic dye in his job and had a history of smoking and drinking whisky and raki daily for 25 years.
