Changes in properties of polyamide netting materials exposed to different environments.

Abstract

Quality of a material and its durability in different environmental condition are two major factors influence the selection of material for fishing gears. A knowledge on the loss of properties is very useful for taking preventive measure. Present study aimed to find the changes in the properties of polyamide monofilament yarns and multifilament twines exposed to three different environments for a period of 90 days. Significant reduction in both breaking strength (P<0.05) and weight (P<0.05) was recorded in the test samples exposed to soil, water & weathering condition. The multifilament twines had more loss in breaking strength and weight than monofilament yarns in all three environments.
