US Patent 5,598,615 (granted Feb. 4, 1997) to Tooru Takada, assigned to K. K. Age of Tokyo, for a silk velvet fabric or jersey and its manufacture. Spun or pure silk is twisted, pasted or steamed, then worked on a pile loom or pile knitting machine. The piece is dipped in lukewarm water to remove the paste, which makes the ground shrink and lock the cut piles in place. The document gives claims, yarn counts, twist levels, shrinkage figures and one cross-section drawing. It contains a USPTO database printout followed by the patent's printed pages.
