摘要： 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.

摘要： 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.

摘要： Manufacturing a spun-dyed para-aramid filament yarn includes (a) preparing a spin dope comprising a para-aramid polymer, at least one dyestuff and concentrated sulfuric acid, (b) spinning the spin dope through a spinneret to obtain spun filaments, (c) coagulating the spun filaments to obtain coagulated filaments, (d) neutralizing the coagulated filaments to obtain neutralized filaments, (e) washing the neutralized filaments to obtain washed filaments, and (f) drying the washed filaments to obtain dried filaments. In step a) the spin dope includes 17.5 to 18.5% by weight of a para-aramid polymer with respect to the weight of the spin dope, and 4 to 15% by weight of the at least one dyestuff with respect to the weight of the para-aramid polymer plus the at least one dyestuff. In step f) the filaments are hold under a tension in a range from 0.2 to 0.8 cN/dtex.

摘要： The invention relates to an apparatus for producing monofilaments or ribbons which are guided in parallel through several treatment devices in an extrusion process. For this purpose, an extrusion device is connected downstream in several treatment device, wherein for guiding the monofilaments or ribbons at least one rod-shaped guide element is provided which has a contact surface for guiding the ribbons or monofilaments. In order to enable low-friction and wear-resistant guidance, in particular when using very elastic monofilaments or ribbons, the contact surface has a multiple coating comprising several coating materials that are applied in several single coatings, each with a different layer thicknesses, wherein the single coatings are formed in a sandwich-like manner on the contact surface.
