  • Publication number: 20230348710
    Abstract: The invention pertains to a composition which is suitable for 3D printing, which composition comprises —a polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, the polyester having an extent of polymerization, which is the ratio of the fraction of functional groups that have reacted to the maximum of those functional groups that can react, of at most 0.6, —solid filler, —diluent. The invention further pertains to a method for preparing a shaped object comprising the steps of —providing a composition as described herein, —extruding the composition through a printer nozzle to form a layer of the composition in a desired shape, building up the layers onto each other to form a shaped object, —subjecting the shaped object to a curing step to form a cured shaped object, wherein the curing step takes place during and/or after the extrusion step. The shaped object is also claimed.

  • Publication number: 20220186024
    Abstract: The invention pertains to a layered high-void-fraction material comprising a composite surface layer comprising structural material and a polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, wherein the surface layer is connected to a high-void-fraction layer of structural material. As compared to a high-void-fraction material without the composite surface layer, the material has, among others, improved surface properties, and improved bending stiffness, while insolation properties for both sound and heat are maintained. The material may be used, e.g., as insulating material, as filtration material, or in hydroponics.

  • Patent number: 11274381
    Abstract: Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
