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 wherein ϰ
i is the linear density of any one of the representative lengths extracted from the monofilament under investigation and Formula 1A is the averaged linear density over the
n = 20 measured linear densities of said

摘要： The invention relates to a process for making a monofilament-like product from a precursor containing at least one strand of fibres made from ultra-high molar mass polyethylene, comprising a) exposing the precursor to a temperature within the melting point range of the polyethylene for a time sufficient to at least partly fuse adjacent fibres and b) simultaneously stretching the precursor, wherein the precursor is mechanically compressed during fusing. The monofilament-like product thus made has a smoother surface appearance, and improved abrasion resistance, for example a reduced tendency to pilling during use as fishing line, than known similar products; making it very suitable for use as fishing line and the like. The invention further relates to a monofilament-like product obtainable by said process, and to semi-finished and end-use products comprising said monofilament-like product.

摘要： The invention relates to a process for making a multi-filament polyethylene yarn via a gel-spinning process, wherein a spin finish is applied at least once in an amount of 0,1-10 mass % based on the filament, to a filament that contains less than 50 mass % of solvent; the spin finish comprising at least 95 mass % of at least one volatile compound having a boiling point at 0,1 MPa pressure of from 30 to 250 °C; and the spin finish is subsequently removed by exposing the filament to a temperature of below the melting temperature of the filament. With this process a yarn is made that has a very low amount of residues on the surface of the fibres, without the need for a washing or extraction step, showing good mechanical properties, and very suited for e.g. biomedical applications. The invention further relates to a process for converting polyolefin fibres into a semi-finished or end-use product. The invention also concerns a polyethylene yarn and a semi-finished or end-use product obtainable by said processes, as well as to the use of thereof in biomedical applications.
