Effect Of Microencapsulating Of Denim Fabrics With Herbal Extract On The Handle And Care Properties

Abstract

In recent years, handle and Care properties has become a major requirement in textiles. .In the present study focuses on the micro-encapsulation to the 100 % cotton denim fabric using three herbal extracts of Ricinus communis, Senna auriculata and Euphorbia hirta to impart their antimicrobial efficiency by finishing the methanol extracts of these herbs on the denim fabric. The combinations of 1 part of Ricinus communis, 3 part of Senna auriculata and 2 part of Euphorbia hirta and conditions by ENISO20645 have been studied and the antimicrobial efficiency of these extracts (1:3:2) and the conditions of 20kgf/cm2 pressure and 20m/min rpm speed are followed by pad dry cure method for best results. To enhance the durability of the finished fabric, treated and washed samples are tested using such test methods- Drape Coefficient (%) (IS 8357/1977) ,Air Permeability Test (IS 11056: 1984) etc ,SEM and FTIR .The result indicated that the drapabilty and crease recovery of the sample was found increased after washes along with air permeability increase.The maximum was noticed in washed samples. Further the stiffness was found predominantly reduced after washing, and no change noticed in water repellency. In the SEM analyzed it was clear that the microcapsules were present in interstices of the fiber assembly of fabric even after 30 washes proving the adherence of the finishing in the samples and in the FTIR the stretching frequencies were found to exist even after 10, 20 and 30 washes.
