Coffee ground residues is considered as biomass and organic wastes that can be used for further application due to their deodorant properties. The purpose of this study is applying anti-odor treatment on 100% wool fabric by bi-functional dyeing process with colorant extracted from coffee ground residues. The extraction was done with water at 100ºC with different extracting ratio. The knitted wool fabrics were IR dyed with extracting solutions at 80ºC, 90 min, then dried at 60ºC, 30 min. The effectiveness of treatment on wool fabric was determined by colour strength K/S and FT-IR spectra. The colour fastness after hand wash were tested by AATCC standard to confirm the treatment after laundering, exhibited good color fastness at grade 4-5. The anti-odor effect was also evaluated according to AATCC 2017 Methods for Odor Evaluation of Textiles and other Materials for fabric before and after laundering, which proved the efficiency of deodorization of treated fabric by coffee residues extraction, even with strong odor like onion |
