Description: The hydrolysis reaction of reactive dyes always accompanies the bonding reaction of the dyes with cellulose substrate. The competitive hydrolysis reaction causes lower fixation levels and is therefore of great environmental and economic importance. The amounts of active and hydrolysed forms of the dyes in the alkaline solution were measured after various reaction times by means of high performance liquid chromatography (HPLC). The hydrolysis rate constants and temperature sensitivities of the particular reactive dyes were evaluated.

Kapok contains a high percentage of inorganic substances, which, in combination with a high percentage of acetylene groups, imparts excellent hydrophobic properties even after removal of waxes. It has low density, an exceptional capability of liquids retention, good anti-microbial properties. It is distinguished from other cellulosic fibres by its excellent thermal and acoustic insulating properties, high buoyancy, and good oil and other non-polar liquids absorbency. It is physiologically inert.
