Utilization of Artocarpus heterophyllus lam seeds for wet processing of textiles – as sizing agent on cottons

Abstract

Artocarpus heterophyllus Lam seeds have potential starch content, which can be used for different end uses. Characterization and application of Jack Fruit Seed Starch (JFSS) as a substitute to commercially available, Arrow root starch (ARS) for sizing of cotton fabrics (Cambric and voile) was carried out in the present study. Starch was extracted from Artocarpus heterophyllus Lam through isolation method, which gave very fine texture on par with ARS. Scanning Electron Microscopy (SEM) analysis revealed that, the size of JFS ranges between 5.5 to 9.03 μm. The pasting character of JFSS has shown a viscosity of 489 with a peak time at 8.74 min and maintaining gelatinization temperature at 85ºC. 5, 10, 15 & 20 percentage of ARS and JFSS were applied to cotton fabric and were tested for geometrical, mechanical and handle properties. Along with control sample (CS) i.e., untreated sample, JFSS treated samples, when tested against ARS treated samples for different fabric properties are found to be on-par with ARS treated samples. Apart from CS and ARS treated samples, JFSS treated samples with 10% followed by15% has shown good tear resistance along with stiff hand. Hence, it can be used as a substitute to commercial starches.
