20200224362 · 2020-07-16 ·

The present invention is to provide a method for manufacturing synthetic leather in which, after obtaining a thickened liquid by adding a thickening agent (B) with an oxyethylene group content of 210.sup.2 mol/g or less to an aqueous urethane resin composition containing an aqueous urethane resin (A) having an acid value of 0.01 mgKOH/g or higher in a range of 0.01 to 30 parts by mass relative to 100 parts by mass of the aqueous urethane resin (A), the thickened liquid is coated on a base and coagulated with a coagulating agent (C) containing a metal salt (c-1). As the thickening agent, it is preferable to use one or more kinds of thickening agent that is selected from the group consisting of a cellulose thickening agent, an acryl thickening agent, and a urethane thickening agent. Furthermore, as the metal salt (c-1), calcium nitrate is preferable.

3D PRINTED ARTICLES OF FOOTWEAR WITH PARTICLES

The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles of footwear containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.
