Abstract
A polyethylene fiber wherein when a free induction decay (M(t)) of the polyethylene fiber at 90° C. measured by a pulsed nuclear magnetic resonance (NMR) solid echo method is approximated to three components of a component (α) having a lowest mobility, a component (β) having an intermediate mobility, and a component (γ) having a highest mobility, by fitting using formula 1 (M(t)=α exp(−(½)(t/T))sin bt/bt+β exp(−(1/Wa)(t/T))+γ exp(−t/T)), a composition fraction of the component (γ) having the highest mobility is 1% or more and 10% or less, and a relaxation time of the component (γ) having the highest mobility is 100 μs or more and 1000 μs or less.
