    Abstract: This invention provides a process for sculpturing pile fabrics which comprises: (a) selectively contacting the surface of a pile fabric corresponding to a pattern a fiber degrading composition, said composition comprising a fiber degrading agent in a concentration sufficient to reduce the tensile strength of the fibers of the pile, said fiber degrading agent being selected from a compound of the formula: ##STR1## wherein R and R' are each independently selected from a lower alkyl group having from one to about five carbon atoms, dyes are optionally selectively applied in pattern form and in register with the fiber degrading composition; (b) heating the pile fabric to temperatures above 180.degree. F. but below 250.degree. F., more specifically, heating with atmospheric steam to degrade the selected fibers of the pile and to provide fixation of the dyes; (c) the fiber degrading agent neutralizing with a solution of a base selected as a hdyroxide, carbonate, or phosphate of group I and II metals; (d) washing the pile fabric with water, to remove any residual components of the fiber degrading composition from the pile fabric; (e) conventionally drying the pile fabric; and (f) removing said selected and degraded portion of the fibers of the pile by mechanical means to provide a sculptured pile fabric.

    Abstract: Organic inherently conductive polymers, such as those based on polyaniline, polypyrrole and polythiophene, are formed in-situ onto polymeric surfaces that are chemically activated to bond ionically the conductive polymers to the substrates. The polymeric substrate is preferably a preshaped or preformed thermoplastic film, fabric, or tube, although other forms of thermoplastic and thermoset polymers can be used as the substrates for pretreatment using, most preferably, phosphonylation-based processes followed by exposure to an oxidatively polymerizable compound capable of forming an electrically conductive polymer. The resultant conductive surface imparts unique properties to the substrates and allows their use in antistatic clothing, surface conducting films for electronic components and the like, and electromagnetic interference shielding. In an alternative embodiment, metals such as gold or platinum are bonded to the chemically interactive surface of a preshaped thermoplastic or thermoset article.
