摘要： The process for production of a heat-stable and light-fast product consisting of multifilaments, monofilaments or flock for textile and industrial applications includes mixing from 0.2 to 0.5% by weight, based on the amount of product, of a UV absorber having a melting point of from 135 to 145° C. and a colorant having a melting point greater than 180° C. with a polyester powder at room temperature to form a starting mixture; feeding from 1 to 100% of the starting mixture and from 0 to 99% by weight PET granules into a cooled feed zone of a twin-screw extruder; operating the twin-screw extruder to melt, knead and homogenize the feed to form polymer strands, which are then cooled and cut to form a compound; and subsequently melt-spinning the compound to form the product. When the product is made by this method the UV absorber is incorporated in the product, thus avoiding the additive-related manufacturing problems.

摘要： The invention relates to a method for producing fine monofilaments with an improved abrasion resistance from a polypropylene with a melt fusion index (MFI) 230 DEG C/12.16 kg of 2-16g/10 min to a titer of 5-20 dtex (0.027 mm-0.053mm). According to said method, a compound of 80 to 99.9 wt. % granulate and 20 to 0.1 wt % of an additive is added to the extruder, the melt is spun at a speed of at least 1200 m/min, cooled in an air bath at room temperature, stretched at a temperature of between 110 and 150 DEG C to a titer of 5-20 dtex and wound. The monofilaments consisting of a polypropylene with a melt fusion index (MFI) 230 DEG C2.16 kg of 2-16g/10 min, improved abrasion resistance and a titer of 5-20 dtex (0.027 mm-0.053mm) have an abrasion resistance

摘要： The invention concerns a method for making propylene monofilaments having a 230 °C/2.16 kg melt flow index (MFI) from 2 to 16 g/10 min, having a diameter larger than 0.050 mm and improved abrasion resistance, which consists in adding to the polypropylene 20 to 0.1 wt. % of an additive upstream of the extruder, spinning the molten material in a water bath, drawing it and winding it. The invention also concerns a polypropylene monofilament having a 230 °C/2.6 kg melt flow index (MFI) from 2 to 16 g/10 min, having a diameter greater than 0.050 mm and improved abrasion resistance, exhibiting a strength of at least 50 cN/tex, for an elongation corresponding to the maximum tensile stress (elongation at rupture) of at least 30 %. Furthermore, it has an abrasion of less than 0.05 % and a relative tensile energy absorption > 100 % after being treated for 24 hours at 120 °C.

摘要： The invention relates to a method for the production of hydrolysis stabilized polyester monofilaments having a diameter of 0.12 - 0.80 mm and a viscosity index (VI) of at least 90 ml/g, wherein a liquid additive mixture consisting of ethylene carbonate and an alkylphosphonium salt as a catalyst is continuously added in a metered manner immediately in front of the extruder. The monofilament produced according to the inventive method is characterized by a residual tear strength of more than 55 % after a 6-day period of treatment in water at a temperature of 125 °C and by a viscosity index of at least 75 ml/g.
