Kier boiling

One principal use of cyclohexanol has been in the manufacture of esters for use as plasticizers (qv), ie, cyclohexyl and dicyclohexyl phthalates. In the finishes industry, cyclohexanol is used as a solvent for lacquers, shellacs, and varnishes. Its low volatiUty helps to improve secondary flow and to prevent blushing. It also improves the miscibility of cellulose nitrate and resin solutions and helps maintain homogeneity during drying of lacquers. Reaction of cyclohexanol with ammonia produces cyclohexylamine [108-91-8], a corrosion inhibitor. Cyclohexanol is used as a stabilizer and homogenizer for soaps and synthetic detergent emulsions. It is used also by the textile industry as a dye solvent and kier-boiling assistant (see Dye carriers).

In the kier boiling of cotton, the action of sodium hydroxide can be intensified by the use... 

It has been demonstrated [186] that the inclusion of polyacrylamide in either enzymatic or oxidative desizing formulations results in increased pick-up of the liquor by the sized warp yams. Desizing by hydrolytic degradation of starch during the traditional kier-boiling treatment using 3°Be sodium hydroxide liquor at 110 °C is now rarely encountered as it is a slow and expensive process [169]. 

Cotton linter was purified by Kier boiling and then bleached with the 4-stage bleaching method, namely, chlorination, hot alkali-refining, hypochlorite and chlorine dioxide steps. 

Cotton is frequently treated with hot alkali in the processes preparatory to dyeing, as well as in the preparation of pure cellulose for research purposes. In the now nearly obsolete process of kier boiling as much as 4% of its cellulose content might be lost as soluble products. The observations that the loss in weight of hydrocelluloses in alkali boiling is directly proportional to the copper number led to the suggestion that short-chain materials were detached from the reducing ends of the hydrocellulose chain molecules and passed into the solution [455]. This was later fully confirmed and the mechanism of the process elucidated [456 64].

Usually, prolonged boiling in acid water and then in alkaline water is used to stabilize NS. However, there are claims that boiling with alkaline water decreases NS stability (Ref 28). However, in a previous publication (Ref 27) these same authors claim that kier-boiling or prolonged boiling in water or in dilute alkaline soln improves stability. Addition of substances such as epichlorohydiin that swell the NS and aid water penetration is claimed to improve stability (Ref 16)...
