Abstract
The invention is concerned with filled multifilament yarn according to the present invention whereby the filler ratio, χ, in the yarn is greater than 0.004 times the IV of the UHMWPE present in the multifilament yarn (IVYUH), i.e. χ≥0.004 g/dL*IVyH, and whereby the tenacity (TEN, in cN/dtex) of the filled multifilament yarn is such that TEN≥IVYUH*(1.5-3.25*χ), or whereby the tenacity of a filled monofilament in the yarn is ten≥IVYUH*(2-4.35*X). The invention is further concerned with a method to manufacture said multifilament yarn and articles comprising said multifilament yarn.
Claims27
A filled multifilament yarn comprising:
- an ultrahigh molecular weight polyethylene (UHMWPE) with an intrinsic viscosity (IVUHY) of <20 dL/g,
- a filler with a numerical average diameter of at least 1 μm and at most 20 μm and an aspect ratio L/D of at least 3 in an amount such that a ratio (χ) of the mass of the filler to a combined masses of the UHMWPE and filler is between 0.06 and 0.50, wherein
- χ>0.004 g/dL*IVUHY, and wherein
- the filled multifilament yarn has a tenacity (TEN) such that TEN≥IVUHY*(1.5-3.25*χ).
