Claims
- 1. Crosslinked polyethylene filaments made of uncoated polyethylene which is stretched and subsequently crosslinked by irradiation of radioactive rays, said uncoated, stretched and crosslinked filaments having an average molecular weight of not less than 4.times.10.sup.5, a tensile strength of not less than 20 g/d and an initial modulus of not less than 400 g/d.
- 2. A method of producing uncoated, crosslinked polyethylene filaments having high strength, high modulus, excellent heat resistance and size stability, comprising the steps of:
- stretching uncoated polyethylene filaments; and
- irradiating the stretched uncoated polyethylene filaments with radioactive rays such that said stretched and irradiated filaments have an average molecular weight of not less than 4.times.10.sup.5, a textile strength of not less than 20 g/d and an initial modulus of not less than 400 g/d.
