Samples employed for the investigation were 3 types of nylon gut used for angling fishery. Both ends of the samples were bound tightly to a tension tester. Let the test piece length be the length of both ends of samples and the length of the knot part used for binding are distinguished from the total length of test piece. Seven kinds of ranging 5-60cm and two types (large and small) of knot part length were employed, and the breaking strength as well as the breaking elongation were measured. The breaking strength (T:Kgw) is expressed as T=kn, where n is the line No. and k is the proportional constant. The value of k ranged 1.5-2.0. The breaking elongation for test piece length 5 cm was 70-110% and when test piece length 60cm showed converging properties at more or less 30%. Breaking elongation of test piece length was approximately 24% and elongation at the knotted part was approximately 20%. The percentage of change of the gut diameter at breaking was approximately 10%. Thus, it became apparent the nylon gut maintains its elongation properties at the knot part when tightly bound., 長崎大学水産学部研究報告, v.66, pp.1-9; 1989}, pages = {1--9}, title = {ナイロンテグスの静力学的特性について}, volume = {66}, year = {1989} }
