阅读说明：本技术 不透明制品和制备方法 (Opaque article and method of making ) 是由 M·奈尔 M·C·布里克 于 2019-08-30 设计创作，主要内容包括：不透明制品具有(i)具有正面和背面的织物；和(ii)具有基材和干燥不透明层的不透明元件,该基材具有第一相对表面和第二相对表面,该干燥不透明层具有内表面和外表面。设置干燥不透明层,使其内表面与基材的第一相对表面接触。干燥不透明层具有(a)40-90重量%的多孔颗粒,其各自具有连续聚合物相和分散在连续聚合物相内的离散孔。多孔颗粒具有2-50μm的众数粒度和20-70体积%的孔隙率。干燥不透明层还含有(b)10-60重量%的粘合剂材料。将(ii)不透明元件层压到织物的背面,以提供不透明制品。(An opaque article has (i) a fabric having a front side and a back side; and (ii) an opacifying element having a substrate with first and second opposing surfaces and a dry opacifying layer with inner and outer surfaces. The dry opaque layer is positioned such that its inner surface is in contact with the first opposing surface of the substrate. The dry opaque layer has (a)40 to 90 wt% porous particles each having a continuous polymer phase and discrete pores dispersed within the continuous polymer phase. The porous particles have a mode particle size of 2-50 μm and a porosity of 20-70 vol%. The dry opaque layer further comprises (b)10-60 wt% of a binder material. (iii) laminating (ii) an opacifying element to the back of the fabric to provide an opaque article.)
