Microwave Assisted Synthesis of Some Azo Disperse Dyes part 3: Dye bath Reuse in Dyeing of Polyester

Abstract

Due to the environmental risks that humans may be exposed to, whether from nature or industrial waste, in this study the water resulting from the dyeing bath was treated with sugarcane bagasse to reduce damage to the environment. Waste water of dye bath was also used to dye the polyester fabrics.

Nano ZnO Provides Multifunctional on Dyed Polyester Fabrics with Enaminone-Based Disperse Dyes

“…It is clear from the table 3, the dyeing treatment before the dyeing process (pre-treatment) with nanooxide particles was better than the treatment for polyester fabrics after the dyeing process (posttreatment) for all dyes 1-6. And in detail with regard to treating polyester fabrics with nano-particles of zinc oxide at a rate of 1 g/L, we find that dyes1 and 6 4), (3)(4), ( 4), ( 4)), it is better than treating polyester fabrics after the dyeing process,…”

“…As a result, some prospective treatments for improving the performance of textiles in guarding against UV radiation, particularly on human skin, have been investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The term ultraviolet protection factor (UPF) was coined to describe the tissue's ability to defend itself from UV light damage [8,9,19].…”
