  • Publication number: 20230416980
    Abstract: A method to manufacture a (recyclable) polyester textile product is disclosed which includes providing a first polyester sheet, stitching polyester yarns through the first sheet to form a pile on a first surface of the first sheet, the pile extending from this first surface, and to form loops of the yarns at an opposing second surface of the first sheet, applying a first quantity of a dispersion including an aqueous dispersion medium and polyester particles dispersed in the medium, to the second surface of the first sheet, thereafter removing the aqueous dispersion medium from the said quantity of the aqueous dispersion, heating the polyester particles to above a temperature at which the polyester of these particles softens, and subsequently cooling the polyester of the particles to below a temperature at which this polyester solidifies to therewith interconnect the loops and the first sheet with the solidified polyester.

  • Publication number: 20230312914
    Abstract: The present invention pertains to a dispersion of polyester particles in an aqueous dispersion medium, wherein the particles have a number average particle size below 1000 nm, and wherein the polyester particles are composed of a polyester material that has a HLB (hydrophilic-lipophilic balance) value between 7.6 and 10.5.

  • Publication number: 20200331254
    Abstract: The present invention pertains to a method for producing and recycling an object consisting of a panel durably provided with a surface covering, comprising bringing the panel and the surface covering in a spatially aligned relationship, providing a layer of hot melt adhesive between the panel and the surface covering, heating the hot melt adhesive to a temperature above its melting temperature, pressing the surface covering against the panel with the molten hot melt adhesive in between the panel and surface covering, cooling down the hot melt adhesive to a temperature below its melting temperature to form the object, and after an end-of-life of the object, heating the hot melt adhesive to a temperature above its melting temperature, and separating the panel from the surface covering. The invention also pertains to a method of producing such an object and a panel for use in this method.

  • Patent number: 8945681
    Abstract: There is described (pref. non-adhesive) coating compositions (which may be either water or solvent borne) that comprise an autoxidisable vinyl polymer, the autoxidisable polymer having a vinyl polymer backbone 25% to 75% by wt of the autoxidisable polymer; fatty acid residue 25% to 75% by wt of the autoxidisable polymer; Tg from ?60° C. to +20° C., Mw from 3500 to 50000 g/mol; and polydispersity from 2 to 10; the autoxidisable polymer obtained by a process of: (A) polymerising ethylenically unsaturated vinyl monomers comprising: at least one epoxy functional vinyl monomer 15% to 100% by wt total monomers in (A); 0 to 85% of at least one other ethylenically unsaturated vinyl monomer, (preferably other than styrenic monomers) by wt total monomers in (A); (B) reacting the epoxy functional polymer from (A) with fatty acids having an average iodine value from 30 to 250 g I2/100 g fatty acid; where composition has: a) a opt.
