Study on Reducing Shrinkage Characteristics Through Woolenized Jute Knitted Fabric

Abstract

The purpose of this study was to investigate the impact of various treatments to solve the problem of considerable shrinking in jute knitted textiles. Without any treatment, jute knit materials naturally shrinks a lot. In this study, firstly 8/1 lb/spindle white tossa jute yarn was selected and a scouring process was applied. Subsequently, the jute yarns were woolenized through 23% sodium hydroxide treatment. After completing the knitting process, the woolenized jute knitted fabrics exhibited a weight of 300- 350 GSM (Grams per square meter). The data were analyzed based on stitch length, compaction, and stentering. The single jersey woolenized jute knitted fabric showed a shrinkage of 4 to 4.5 after the experiment, however, 1x1 woolenized jute knitted Lycra Rib (double jersey) fabrisc showed a more shrinkage range from 4.7 to 5. These findings demonstrate that the proposed treatment method can help reduce the shrinkage of jute knitted fabrics, making it a promising approach for achieving enhanced performance in jute knitted products. The study was conducted at the pilot plant and processing division of the Bangladesh Jute Research Institute. Keywords: Jute wool, shrinkage effect, Jute knitted fabrics, woolenisation effect .
