US Patent 3,377,678 (granted 16 April 1968 to Toshihiko Moriya, assignor to Nihon Vinylon Co., Tokyo) describes a method of making embroidery lace. A fine foundation cloth is woven from hot-water-insoluble yarn (nylon, polyester, silk or cotton, 10-40 denier) combined with hot-water-soluble polyvinyl alcohol or alginic acid yarn. The cloth is embroidered with insoluble thread, then immersed in hot water to dissolve the soluble yarns, leaving a delicate guipure-like lace. The patent includes a drawing sheet with three figures, four worked examples with yarn sizes and dissolving temperatures, and nine claims.
