Patent ID: 8137809

Claim:
A gel spun, ultrahigh molecular weight polyethylene (UHMWPE) multifilament yarn, wherein the yarn comprises individual monofilaments having a coefficient of variation of their linear density, hereafter CV intra , of less than 30%, wherein the CV intra of a monofilament was determined from linear density values corresponding to a number of 20 representative lengths randomly extracted by cutting from said monofilament and using Formula 1 CV INTRA = ∑ i = 1 n ⁢ ( x i - x _ ) 2 n - 1 × 1 x _ × 100 Formula ⁢ ⁢ 1 wherein x i is the linear density of any one of the representative lengths extracted from the monofilament under investigation and x is the averaged linear density over the n=20 measured linear densities of said n=20 representative lengths.
