    摘要: A process for producing a polymeric-type film in the surface of cellulosic fibers is disclosed. Cellulosic fibers are irradiated in the colored area of a radiofrequency plasma of ammonia for a period of about 10 minutes to 2 hours in a reactor designed to admit ammonia between electrodes at a rate such that all of the ammonia molecules have been activated to plasma. A polymer coating is formed in the surface of the cellulosic fibers that is alkali resistant, water-repellent and improves the wrinkle recovery of the fabrics.

    摘要: Novel cellulosic fiber with improved resistance to abrasion and increased permeability to chemicals characterized by highly stable crystalline cellulose III and cellulose IV forms is disclosed. Cellulose selected from either fiber, yarn, fabric, cotton, or mercerized cotton is treated with ammonia vapors at from about ambient to 140.degree. C. and from about 100 psi to 1700 psi for sufficient time to alter the interatomic planar distances and produce stable crystalline cellulose III polymorph. Crystalline cellulose III can also be immersed in ethylenediamine and then boiled in dimethylformamide to completely convert the III to cellulose IV.

    摘要: Electrically conductive glasslike films have been produced on the surface of various types of glass and porcelain by heating plumbite-treated cellulosics while one surface of the plumbite-treated cellulosic was in contact with glass or porcelain and the other surface of the cellulosic was covered with either aluminum foil or powder. The heating was carried out in a closed oven with a limited availability of oxygen. The various glasses and ceramics treated by the process of this invention were imparted a conductive coating or surface which appeared to be rigid with respect to abrasion and grey with respect to coloration.
