Abstract

The effect of cleanness defects of raw silk on tenacity and elongation has been studied to quantify the extent of damage. Multivoltine raw silk reeled on multiend reeling machine was used for the experiment. About 100pairs of defective part and the adjoining normal part were tested for strength and elongation. It has been observed that around 85% of the cleanness defects show a decrease in strength and elongation. Cleanness detects with additional material attached to raw silk do not affect the strength and elongation. The average decrease in strength and elongation of defective parts is 18% and 39% respectively. Around 20% of the defects show a tenacity of3 gjden and below and around 38% of the defects show an elongation below 15%.
