US Patent No. 1,661,142, granted 28 February 1928 to Clarence Lipper of Philadelphia, assignor to Lipper Manufacturing Co. It describes a loom-woven fabric made to look and feel like hand-crocheted hat fabric. The fabric uses a composite weft of a cotton core, a loosely spiralled stiff cellulose (artificial straw) body thread and a binder thread of artificial silk. The warp is two sets of plain warp threads plus a doup warp. The patent has two figures (fabric plan view and composite weft) and 16 claims.
