WATER REUSE IN THE TEXTILE INDUSTRY’S DYEING PROCESS

WATER REUSE IN THE TEXTILE INDUSTRY’S DYEING PROCESS

COGORNI, A.; VAZ, C.; LICODIEDOFF, S.; KOSLOWSKI, L. A. D.

Artigo:

Textile industries produce a great amount of water retrieved from processed material, with a very high production of liquid effluents and pollution charge. Current analysis demonstrates the viability of direct reuse of the liquid flow of textile effluents from the dyeing process of cloth made of 100% PES (Polyester), 100% PES/PUE (Polyester with elastane) and 100% PA (Polyamide). This fact implies tolerance limits for the approval of dyed substrate tonality as a variation of tonality (∆E), tissue solidity test and pH in dyeing baths. All types of dyeing and analyses were performed at a laboratory scale in a textile industry in Joinville SC Brazil. A 75% saving in auxiliary dyeing products occurred, coupled to a 40% decrease of effluent that would be used in the liquid treatment process.
