Making various monofilaments by spinning and stretching of Ziegler process low pressure polyethylene, the tensile elastic recovery characters of the monofilaments and its ropes were determined. The results are as follows:
1) In relationship between elastic recovery and stretch ratio, monofilaments of higher ratio have lower recovery character at constant extension test method, and higher character at constant load test method.
2) Elastic recovery of Ziegler polyethylene monofilament is less than Nylon-or polypropylene-monofilament.
3) The elastic recovery curves of various fibers after unloading much resemble in type and the great part of elastic recovery occure within one minute.
4) In the case of rope, cord and twine made by twisting multiple monofilaments, because of slip deformation occured between filaments during tension, the filament size and the coefficient of friction have much influence on recovery resistance.
5) The rope of Ziegler polyethylene monofilament has superior tensile elastic recovery character at wet state than each rope of Nylon multifilament, Vinylon spun yarn or Manila.
