Jet Dyebath Reuse in the Coloration of Polyester Knits
Multicycle reuse of disperse dyebaths on pilot scale jet equipment was investigated in dyeing of staple and filament 100% polyester knit fabrics. Long reuse runs of single shades produced good batch-to-batch shade uniformity. Multishade reuse runs were found feasible in the forward (light-mediumdark) direction for both fabric types even though dyes were not completely common in successive shade...
متن کاملEnergy Conservation in Carpet Dyeing by Dyebath Recycling
ABSTMCT: Reduction in the requirements for water, energy, and chemicals have been achieved by changes in carpet beck dyeing procedures. Instead of discharging the dyebath following each dye cycle, in the new procedure the spent bath is analyzed, reconstituted to the desired concentration of dyes and auxiliary chemicals, and reused. Bench scale dyeings were conducted initially to define operat...
متن کاملOne-pot synthesis of disperse dyes under microwave irradiation: dyebath reuse in dyeing of polyester fabrics.
A series of 4-hydroxyphenylazopyrazolopyrimidine disperse dyes were prepared via one-pot reactions of p-hydroxyphenylhydrazone, hydrazine hydrate, and acetylacetone or enaminones using microwave irradiation as an energy source. Structural assignments of the dyes were confirmed by X-ray crystallographic structure determination. Instead of discharging the dyebath after each dyeing cycle, the resi...

Until the brain is capable of supporting a level of symbolic complexity such that social life itself can be symbolically organized, then symbolism may be of only marginal consequence. What, then, were the selective factors behind this watershed transition? Social Complexity and Cogn...
