Abstract: A method and an installation for producing a twisted synthetic yarn, comprising a spin-drawing installation configured to produce continuous filaments from a liquid plastics material or granular material by at least one spinneret and then to produce at least one yarn from at least two continuous filaments. A downstream treatment apparatus treats the at least one yarn which is transferred, without interruption, from the treatment apparatus to a downstream twisting/cabling apparatus via a collection and transport apparatus in a continuous process from the spin-drawing installation to the twisting/cabling apparatus. The collection and transport apparatus is configured to compensate for a difference in a production speed between the spin-drawing installation and the twisting/cabling apparatus.

Abstract: This invention involves a new and better solution to the problems associated with the premature softening of PLA filaments in the additive manufacturing of three dimensional articles. It is based upon the finding that poly(lactic acid) filaments with high crystallinity offer much better resistance to heat-induced softening. The crystalline poly(lactic acid) filament of this invention can accordingly be used in the additive manufacturing of three dimensional articles without encountering the problems associated with premature softening, such as poor quality and printer jamming. The crystalline poly(lactic acid) filaments of this invention can also be used in additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, or leading to increased printer complexity. This invention more specifically discloses a filament for use in three-dimensional printing which is comprised of crystallized poly(lactic acid), wherein said filament has a diameter which is within the range of 1.65 mm to 1.85 mm.

Abstract: The invention discloses a method for preparing nylon yarns. The method comprises the following steps: mixing, blending, spinning, cooling and then winding an organic copper complex, color masterbatches and PA6 slices into bobbins, wherein the organic copper complex is obtained after a coordinated ionic liquid reacts with copper powder oxidized by an oxidant, and the color masterbatches are obtained through blending granulation of the PA6 slices, germanium powder slurry and modified negative ion far-infrared powder. The method has the beneficial effect that the nylon yarns obtained by the preparation method are healthier and safer to the human body.
