The Federal Trade Commission announces amendments to Rule 7 of the Rules and Regulations Under the Textile Fiber Products Identification Act (``Textile Rules''), which lists generic names and definitions for manufactured fibers. 16 CFR 303.7 (1996). The amendments create a new subsection that designates a new fiber name, ``elastoester,'' and establishes a definition for the fiber. The Commission initiated this proceeding in response to a petition for a new generic fiber name under the Textile Rules filed by Teijin Limited, a fiber manufacturing company based in Osaka, Japan. Teijin manufactures the fiber under the trade name ``REXE.'' The Commission is making the amendments effective today, as permitted by 5 U.S.C. 553(d), because the amendments do not create new obligations under the Rule; rather, they merely create a fiber name and definition that the public may use to comply with the Rule.
