THE INFLUENCE OF INDUSTRIAL FINISHING TREATMENTS AND THEIR SUCCESSION ON THE MECHANICAL PROPERTIES OF DENIM GARMENT

Abstract The principal aim of this work is to study the effect of matter, types of launderings (stone wash, enzyme wash, mixed wash and rinse), special treatments applied during the manufacturing process of garment washing (brushing, sanding, resin-treatment, bleach-treatment, permanganate-spray and softening) and their succession on the fabric mechanical properties: Tear strength (T. S) and Breaking strength (B. S). The results show that all these treatments, applied to obtain more worn appearance and aged look for garment has decreased the mechanical properties. Moreover, the resin- treatment is the most aggressive for cloths in the set of the special treatments. In fact, whatever the following washing process is stone washing or mixed washing, the finishing resin-treatment destroys the matter and reduces a lot the mechanical resistance. Thus, we proved that in the case of washed denim fabric, it is advisable to avoid the line of succession of treatments containing the resintreatment and mixed washing process.
