Cotton and regenerated cellulose had been hydrolyzed under acid conditions on thermally pretreated and untreated samples. Three to four times higher rate constants could be calculated from the loss in DP of the acid-hydrolyzed thermally pretreated ce

Dyeings on cellulose produced with four different azo reactive dyes were exposed to the action of cellulase enzymes. The analysis of the resultant fabrics indicated that the level of depolymerization decreased with increasing concentration of covalen

Cotton cellulose was swollen in a sodium hydroxide solution and carboxymethylated by a two-bath method for different periods of time for each process. The kinetics of acid hydrolysis and the crystallinity of the swollen and carboxymethylated samples

Presented at the 13th Congress of the International Federation of Associations of Textile Chemists and Colourists in London on 20 September 1984. Processes induced by two kinds of illumination (ultra-violet and Xenotest) in wool dyed with reactive dy

A modified mathematical model has been derived for the description of the reactive dyeing mechanism of cellulose. For the experiments film and fabric based on regenerated cellulose and a dye of monochlorotriazine type (C.I. Reactive Red 43) have been

Radiometric method was developed for the analysis of endogenous formaldehyde in human blood and urine using dimedone-14C reagent. The method based on that dimedone /5,5-dimethyl-cyclohexane-1, 3-dione/ can very easily condense with formaldehyde and o

Summary The possibilities of industrial uses of various cation-exchange resins have been studied in acetic acid esterification reactions. Catalytic activities and life-times of resins have been studied and compared. The oleophilic sulphonated styrene

For the inhibition of spontaneous N epsilon-methylation and N epsilon-formylation reactions between L-lysine and formaldehyde, L-ascorbic acid proved to be most suitable. The inhibition was not complete unless the molar concentration of ascorbic acid
