Zusammenfassung: | To provide very long, filled multifilament yarn that limits or even prevents filament or even yarn breakage during manufacture of the yarn and also during processing of the yarn into articles.SOLUTION: The present invention relates to filled multifilament yarn comprising UHMWPE with an intrinsic viscosity and a filler with a diameter of at most 20 μm in an amount such that the ratio of the mass of filler to the combined masses of the UHMWPE and filler is between 0.02 and 0.50, where the intrinsic viscosity is at most 225 times the filler ratio, and where at least (i) the coefficient of variation in linear density between the filaments of the yarn is at most 12%, (ii) the coefficient of variation in tenacity (ten) between the filaments of the yarn is at most 12%, or (iii) the coefficient of variation of the Tenacity (TEN) of the multifilament yarn is at most 1.0%. The application further relates to a method of producing such yarn, and articles comprising such yarn.SELECTED DRAWING: None
【課題】糸の製造中、また糸から物品への加工中のフィラメント又はさらには糸の破壊を制限し、又はさらには防止する、非常に長い充填剤入りマルチフィラメント糸を提供する。【解決手段】充填剤入りマルチフィラメント糸であって、ある固有粘度を有するUHMWPEと、充填剤の質量の、UHMWPE及び充填剤の総質量に対する比が0.02~0.50の間となる量の最大20μmの直径を有する充填剤とを含み、上記固有粘度が上記充填剤比の最大225倍であり、少なくとも、(i)上記糸のフィラメント間の線密度の変動係数が最大12%となる、(ii)上記糸のフィラメント間のテナシティ(ten)の変動係数が最大12%となる、又は(iii)マルチフィラメント糸のテナシティ(TEN)の変動係数が最大1.0%となる、充填剤入りマルチフィラメント糸に関する。本出願はさらに、このような糸の製造方法、及びこのような糸を含む物品に関する。【選択図】なし |
