摘要:
Glasslike materials have been produced by heating plumbite-treated cellulosics in a limited oxygen atmosphere while in contact with a glass or ceramic surface. Cotton-lace, knits, and other designs of cellulosic materials can be applied to glass or ceramic surfaces by process of this invention. Glass or ceramic materials have been joined together to form a strong bond by placing a piece of the plumbite-treated cellulosic material between the glasses and heating the assembly in a limited oxygen atmosphere. Etching of glass has also been achieved by process of this invention.

摘要:
This invention relates to a process for converting cellulose to amino acids by radiofrequency plasma of nitrogen and hydrogen gases. Cellulose is placed between the electrodes in a radiofrequency plasma reaction chamber which is sealed and maintained at a reduced pressure. Hydrogen and nitrogen mixture is bled through the chamber and sufficient radiofrequency electric current applied until the cellulose is consumed, thereby producing a mixture of amino acids. The cellulose can be either cotton or wood derivatives.
摘要:
Certain chemically modified cotton fabrics have been treated with vapors of glycidol at reduced pressures in a heated chamber to impart improved wet and dry wrinkle recovery characteristics.
摘要:
Partially Aminoethylated cotton fabric is reacted with either propylene carbonate (4-methyl 1,3 dioxol-2-one) or ethylene carbonate (1,3 dioxol-2-one) with potassium carbonate as catalyst. Reaction is carrid out in a heated vacuum oven. The resultant product has urethane crosslinks and improved wrinkle recovery properties.

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.
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:
Cellulosic fabric is reacted with a mixture of diethylene glycol, dibasic acid, and either ethylene carbonate (1,3 dioxol-2-one) or propylene carbonate (4-methyl 1,3 dioxol-2-one) in a heated evacuated oven. The resultant product has polyester linear grafts and crosslinks and improved resistance to wrinkling.
摘要:
Partially carboxymethylated-cotton fabric prepared by a non-aqueous procedure is reacted with either ethylene carbonate or propylene carbonate in a heated, evacuated oven. The product of either reaction is a fabric with high conditioned and high wet wrinkle recovery.
