Explored Agro-waste Starches/Gums as Thickening/ Binding Agents for Textile Printing/Sizing

Starches, Gums/Mucilage are highly viscous in nature, so, in the present study agro waste plant sources, namely Jack fruit seeds (JFS), Mango kernel (MK) and Lasoda fruit (LF) were explored to extract starch/mucilage content. Compositional analysis revealed that presence of carbohydrate content in JFS and MK powder, mucilage content of Lasoda fruit contributes good substitute to binding/sizing agents in textiles. SEM analysis revealed particle size of - JFS powder as 5.87-14.4m lengthwise and 5.87-11.8m on width direction, MK powder as 18.2-20.1m length wise and 9.61-15.7m width wise, which was efficient enough to penetrate into fiber polymer structure. Also viscosity reveals that, selected sources were suitable for printing/sizing, with an appreciable viscosity of 11.9, 7.86 & 3.86 centi-poise for MK, JFS and LF respectively.
