Abstract: This invention provides a method for the treatment of cellulose containing fabrics with inorganic phosphorylating agents to obtain durable press or smooth drying fabrics. The method involves treating the cellulose-containing material with 8-16% of an inorganic phosphate, 16-32% of urea, 0.5-2.0% of a catronically emulsified polyethylene fabric softener, 0-6% of a polyacrylate or suitable polymer emulsion (glass transition temperature: -20.degree. to -43.degree. C.), and then drying the fabric at 60.degree.-100.degree. C. for 3-7 minutes. The fabric is crosslinked to obtain durable press or smooth drying properties by curing at 160.degree.-170.degree. C. for 3-9 minutes.

Abstract: The hot-callusing method and apparatus of the invention direct heat to the graft union area of plants or trees to accelerate the callusing of the stock and scion while leaving the remaining plant parts unheated. The apparatus comprises a tube having openings of sufficient size to at least partially enclose the area of the graft union to be callused and to confine heat in said area and a means for providing heat to the graft union area.

Abstract: Water-insoluble chemical biological agents to be encapsulated are dispersed in an aqueous paste of a starch-containing material alkoxide. Subsequent addition of selected water-soluble alkali earth metal cations insolubilize the paste, thereby entrapping the agents in a protective matrix. Encapsulation of biologically active compositions provides a shield against hostile environments, improves safety in handling, and slows the release of such compounds to the surrounding medium. Highly volatile liquids are protected against losses by evaporation. Encapsulation also provides protection against decomposition from exposure to ultraviolet light.

The harvester is also provided with mechanisms for automatically removing or clearing it of branches and debris and for repositioning rods which are moved out of operating position during the harvesting operation.

Abstract: The alkali metal salts of fatty acids (soaps) remaining in fatty acid ester products after interesterification and other processing steps are decomposed by dissolving the fatty acid ester product in a suitable solvent, adding water, saturating the mixture with carbon dioxide, removing the water phase containing excess carbon dioxide and bicarbonate of the alkali metal, converting the bicarbonate into carbonate, and using the carbonate in refining, interesterification and other reactions in the processing of fatty acid esters.

Abstract: Zwitterions are employed as catalysts in a chemical finishing process to treat cellulosic textiles with crosslinking agents and produce easy-care properties in the finished materials. The process comprises treatment of the textile material, such as cotton fabric, by impregnating it with a solution containing a cellulose-crosslinking agent and, as catalyst a zwitterion, alone or in combination with a magnesium salt, drying and curing the fabric. Said finished fabrics are characterized by an unusual combination of useful, desirable properties--smooth-drying appearance, wrinkle resistance, serviceable strength, and inoffensive formaldehyde release.

Abstract: The title compounds, having the formula (RO.sub.2 CNHCH.sub.2).sub.3 PY where Y=oxygen or sulfur, are prepared by reacting a tris(N-carbalkoxylaminomethyl)phosphine, having the formula (RO.sub.2 CNHCH.sub.2).sub.3 P, with an oxidizing or sulfurizing agent. The products, after methylolation with formaldehyde, are useful as finishing agents for imparting flame retardant properties to cotton fabrics.

Abstract: Complex mixtures of branched chain fatty acids or esters in which the yield of monomeric branched chain products are substantially increased and the yield of polymeric products substantially decreased are prepared by heating monounsaturated fatty acids or esters in the presence of certain combinations of catalysts.

Abstract: An apparatus to uniformly wrap filament around the surface of a spun core yarn is disclosed. Means for fabricating a core yarn is provided. At the critical point of yarn fabrication, the spun core is simultaneously twisted or rotated on its longitudinal axis by means of ring spinning and contacted with a filament introduced by means of over-feed rollers. Helical wrapping of the filament around the surface of the staple core yarn takes place as the filament cohesively contacts the twisting core yarn to form a composite filament wound yarn.

Abstract: This invention relates to the transfer printing of cellulosic fabric by in situ polymerization of monomers to form polyamides and polyesters. The process involves treating the fabric with a diamine or bisphenol and then treating with a diacid chloride, drying, rinsing with neutralizing agent, and then heat transfer printing the fabric after drying. The reverse procedure can also be employed in which case the fabric is treated initially with the diacid chloride.
