Claims7
A polyethylene yarn having a weight average molecular weight of 80,000 to 160,000 g/mol, a strength of 11 to 18 g/d, an initial modulus of 150 to 200 g/d, an elongation of 6 to 10%, and a dry heat shrinkage at 100° C. of 3.0 to 3.5%,
- wherein a ratio of a storage elastic modulus at 50° C. to a storage elastic modulus at 30° C. of the polyethylene yarn is 65 to 75%,
- a ratio of a storage elastic modulus at 80° C. to a storage elastic modulus at 30° C. of the polyethylene yarn is 30 to 45%, and
- a ratio of a storage elastic modulus at 105° C. to a storage elastic modulus at 30° C. of the polyethylene yarn is 10 to 25%.
