The Durability of Polybutylene Succinate Monofilament for Fishing Net Twines by Outdoor Exposure Test

Abstract

Biodegradable polybutylene succinate(PBS) is a kind of environmentally friendly plastics for fisheries, because it can mitigate the ghost fishing problem caused by gill-net and trap fisheries. To evaluate durability of PBS monofilament, each of different diameter 3 types of monofilaments were spun and exposed to 56 month outdoor and then their gravity, modification of surface, breaking strength, and elongation were analysed. The gravity of PBS monofilament was estimated to be approximately 1.24 when spinning ratio from 4.8 to 6.1. PBS monofilaments did not show any crack after 56 month exposed to outdoor and load-elastic elongation curve was showed sigmoid type. Decreasing ratio of elongation was appeared in the thinnest monofilament 0.2mm diameter and breaking strength was in the thickest monofilament 0.4mm diameter. Breaking strength and elongation at break were decreased rapidly after 48 month exposed to outdoor. Breaking strength reduced linearly after 48 month exposure, while no such linear relationship was found in the case of elongation at break. In results, it was investigated that the durability of PBS monofilament nets for gillnet and trap were 24, 50 month when keep to land, respectively.

The Production and Physical Characterization of Polybutylene Succinate Multifilament Yarns

“…Mechanical properties such as tensile strength, elongation and softness are important in this application area, and it has been observed that the mechanical properties of PBS monofilament are maximized by being mixed with 5% measured by weight polybutylene adipate-co-terephthalate. In addition, good durability of PBS monofilaments for outdoor use has been demonstrated [33,34]. In the study on PBS homopolymer; bulk continuous filament (BCF) and continuous filament (CF) fibers were obtained while extruder temperatures were stated to be in the range of 200-230oC.…”

Monitoring-System Development for a Bottom-Set Gillnet through Time-Domain Dynamic Simulations

“…In this study, a bottom-set gillnet, which is one of the most widely used types of fishing gear in Korea [16], was selected. A bottom-set gillnet generally consists of a long, slender net (also defined as the net assembly in this study), mooring lines and ropes, and location buoys.…”
