Title : Benefit study of ecological compounds GALACID XT 88 based on lactic Acid and GALASOLV NF 62 based on ethyl lactate and their impact on the surface and mechanical properties of cotton fabrics
Abstract:
Two compounds "GALACID XT 88" based on lactic acid and "GALASOLV NF 62" based on ethyl lactate as being a green solvent, which are biodegradable and renewable compounds. In this study ,we attempted these compounds to use in finishing treatment, especially applied on cotton denim fabric in order to get 3D effects like fashion require. The mechanical, morphological, microscopic characterizations as well as the evaluations obtained were elaborated on the treated fabrics in two steps; before wash BW and after wash AW. In two steps of finishing , Both compounds give acceptable Dry crease recovery angle, but it seems that compound based on ethyl lactate is better in DCRA quality compared to compound based on lactic acid after wash. We finish that the ecological compounds gives a satisfy quality of 3 D effects. Consequently, these compounds preserve the mechanicals properties during two steps (GALACID XT 88 causes loss of 25 % max. and GALASOLV NF 62 cause loss of 8 % max.). These results are proved using Kawabata evaluation system and Surface morphology by SEM. Indeed these compounds improve the quality of treated fabric.
