    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： A catalyst system comprised of copper sulfate and hydrogen peroxide is utilized to cure unsaturated flame retardants on textiles. The resultant flame retarded textiles have unusually good hand (softness); even with high add-on (weight percent of chemicals applied to a textile) of the flame retardants. Conventional techniques and equipment can be used with the system of the present invention.

    摘要： A method for modifying fibers of a fabric which comprises applying an effective amount of an aqueous salt solution to the fabric to sufficiently wet all of the fibers of the fabric with the salt solution, removing excess solution from the fabric, contacting the wetted fabric with a pair of electrodes through which a sufficient electromotoric force is aplied to the salt solution in the fabric to generate an acidic and/or caustic solution at or near the surface of the fabric. Thereafter, the fabric is heated for a period of time and at a temperature effective to produce a chemical reaction between the fibers wet with the acidic and/or caustic constituent resulting from the above electrolysis of the aqueous salt solution. After the desired degree of fiber modification has occurred, the chemical reaction is quenched and the resulting product recovered. The particular salt constituent employed in the aqueous salt solution will be dependent upon whether the desired fiber modifying agent is an acid, base, or both.
