Abstract
A polyethylene fiber characterized by having an intrinsic viscosity [η] of 0.8 dL/g or more and less than 5 dL/g; being composed of a repeating unit substantially derived from ethylene; having pores formed inside of the fiber; having an average diameter of the pores of ranging from 3 nm to 1 μm when the diameter is measured, by each pore being approximated by a column, at a contact angle of 140 degrees, in a mercury intrusion method; a porosity of the pores of ranging from 1.5% to 20%; and having a tensile strength greater than or equal to 8 cN/dtex.
Claims18
A polyethylene fiber comprising a polyethylene, wherein
- the polyethylene has an intrinsic viscosity [η] of greater than or equal to 0.8 dL/g, and less than 5 dL/g, and substantially contains ethylene as a repeating unit,
- the polyethylene fiber comprises pores formed inside of the fiber,
- the average diameter of the pores is in the range of from 3 nm to 200 nm when the diameter is measured, by each pore being approximated by a column, at a contact angle of 140 degrees, in a mercury intrusion method,
- the porosity of the fiber is in the range of from 1.5% to 15%, and
- the polyethylene fiber has a tensile strength greater than or equal to 8 cN/dtex.
