Sustainable dyeing of jute fabric with natural dye sources by cold pad batch technique

Abstract

Jute is popularly known as perishable, reusable and ecological friendly fiber having golden & silky shine appearance; therefore termed as the Golden fibre in Bangladesh. Jute is budget friendly vegetable fiber procure from the bast or skin of the plant's stem and most important fiber after cellulosic cotton fibre in terms of variation in usage, universal consumption generation & availability. Natural dyestuffs are popular now days for sustainable issues in textiles industries. This research was focused on environment friendly natural dyeing technique on jute fabric with natural dye sources through cold pad batch (CPB) dyeing technique. Java plum fruit, kadamba flower & malbar spinach vegetable were selected as natural dye sources and extracted dye liquors using methanol solvent. Evaluated dyed samples by color co-ordinate values by spectrophotometer where lighter to darker shades were achieved on dyed Jute samples with the dye extracts and K/S value was analysis to assess color strength among dyed samples. Different Color fastness test was done to find better dyeing performance on jute where sample dyed with malbar spinach vegetable extract showed better performance compared to other dye extracts. Moreover, the research was intended to observe dyeing possibilities of jute fabric with natural sources without focusing on mordant for opening a new export area of sustainable dyed jute goods maintaining sustainable textile processing.
