Abstract
The present invention discloses a colored stretched polyethylene material which comprises an ultra-high-molecular-weight polyethylene having an intrinsic viscosity of 5-50 dl/g in decalin at 135.degree. C. and 0.001-50 parts by weight, per 100 parts by weight of the polyethylene, of a dye and/or a pigment and which has been stretched at a temperature lower than the melting point of the polyethylene, and a process for producing said polyethylene material. This colored stretched polyethylene material has a tensile modulus of 120 Gpa or more and a tensile strength of 1.5 GPa or more.
