fluid applied to fluid filaments obtained by spinning a solution of UHMWPE through a spinneret and into an air gap, is at least 450, wherein DR
fluid = DR
sp * DR
ag , the DR
sp and DR
ag being the draw ratios in the spinholes and in the air gap, respectively; and provided that DR
ag is at least 30. The UHMWPE multifilament yarns produced thereof were characterized by a tensile strength of at least 3.5 GPa and contained filaments having a dtex of at most 0.5. The invention further relates to products comprising said yarns, e.g. fabrics, medical devices and composite and ballistic articles.-

摘要： Process for removing residual spin solvent from a gel spun, UHMwPE filament having an effective diameter of above 16 μm, comprising the steps of: removing residual spin solvent from the filament to a level of below 100 ppm at elevated temperature, while keeping the filament taut. The invention also relates to gel spun UHMwPE filament having an effective diameter of above 16 μm and a residual spin solvent residue of less than 100 ppm. Preferably the filament has a creep rate, measured at 5O °C, under a load, so that the initial stress is 600 MPa, of less than 5⋅10-6 sec-1.

摘要： The invention relates to a process for producing gel-spun ultra high molecular weight polyethylene (UHMWPE) fibres having high tensile strengths and improved creep rates wherein the UHMWPE used in said process comprises per thousand carbon atoms between 0.1 and 1.3 methyl side groups; and between 0.08 and 0.6 of methyl end groups; and wherein the overall draw ratio (DRoverall = DRfluid x DRgel x DRsolid) is at least 7000 provided that the fluid draw ratio DRfluid = DRsp x DRag is at least 100, wherein DRsp is the draw ratio in the spinholes and DRag is the draw ratio in the air gap. The invention further relates to gel-spun UHMWPE fibres produced thereof. The gel-spun UHMWPE fibres of the invention have a tensile strength of at least 4 GPa, and a creep rate as measured at 70°C under a load of 600 MPa of at most 6 x 10-7 sec-1. The gel-spun UHMWPE fibres produced thereof are useful in a variety of applications, the invention relating in particular to ropes, medical devices, composite articles and ballistic-resistant articles containing said UHMWPE fibres.

摘要： The invention relates to a process for making a monofilament-like product from a precursor containing a multitude of continuous polyolefin filaments, comprising exposing the precursor to a temperature within the melting point range of the polyolefin for a time sufficient to at least partly fuse adjacent fibres and simultaneously stretching the precursor at a draw ratio of at least 2.8. With the process according to the invention a monofilament-like product can be made that shows improved tensile properties; making it very suitable for application as e.g. fishing line.

摘要： The invention relates to a process for making a polyethylene multifilament yarn comprising the steps of a) spinning multiple filaments from a solution comprising between 0.5 and 30 mass% of ultra high molecular weight polyethylene in a solvent; b) cooling the filament obtained to form gel filaments; c) removing at least partly the solvent from the gel filaments; d) drawing the filaments in at least one drawing step before, during or after removing the solvent, wherein the solution of step a) further comprises between 0.1 and 7 mass% of a sorbitol derivative and at step d) the filaments are drawn with a draw ratio of more than 15 to a strength of at least 1 GPa. The invention further relates to a high performance polyethylene multifilament yarn having a strength of at least 1 GPa, wherein the yarn comprises between 0.1 and 5 mass% of a sorbitol derivative.
