Extraction of Pectic Acid from Citrus Fruit Peels and its Application as Textile Printing Thickener by Latest Trends in Textile and Fashion Designing in LupinePublishers.
Extraction of pectic acid by acid hydrolysis from citrus fruit peels and
its conversion in to textile printing paste thickener in order
to use it as an alternative substitute of sodium alginate thickener in
reactive printing was studied in this research. Printing with the
alternative thickener, sodium pectate, printed fabric characteristics;
color yield, color brightness and wash fastness were improved.
Pectic acid is extracted from the identified citrus fruit peels i.e.
orange peel, lemon peel and bitter orange peels. Extraction time, type
of solvent and extraction pH was standardized based on pectin yield
obtained. The research found environment friendly extraction
of pectic acid by sodium carbonate instead of acid hydrolysis with HCL
or H2SO4.
