  • Patent number: 4083995
    Abstract: (Z)-9-Tetradecen-1-ol formate [(Z)-9-TDF], a chemical of nonbiological origin, was prepared and found to have excellent potential as an insect control agent for the corn earworm, Heliothis zea (Boddie) and tobacco budworm, H. virescens (F.). Mating of H. zea and H. Virescens moths exposed in the field to an atmosphere permeated with (Z)-9-TDF was greatly reduced. The chemical can be used alone to inhibit mating of H. zea or H. virescens or it can be dispensed together with other mating inhibitors to suppress mating in several pest species simultaneously.

  • Patent number: 4070505
    Abstract: Paramagnetic susceptibility has been imparted to raw unprocessed cotton fibers by impregnating the fibers with a paramagnetic organometallic rare earth compound dissolved in hydrocarbon solvent.

  • Patent number: 4068167
    Abstract: A unique radial electrode has been designed in the same configuration as the feed roller of a cotton ginning system. The electrode is then installed as part of a feed roller and properly insulated from the ginning system. When seed cotton is fed between the feed rollers the charged radial electrode becomes a signal electrode communicating with the rest of the system which forms as a ground. The resultant current flow between the electrode and the ground passing through the seed cotton produces a measure of the moisture in the seed cotton.

  • Patent number: 4067689
    Abstract: Diethylaminoethyl (DEAE)-Cotton, prepared so that the tertiary amine nitrogens have unshared electrons and are thus in the Lewis-base form, is reacted with an alcoholic solution of an alpha-omega dihaloalkane to quaternize amino groups. The fabric produced by this process is crosslinked between tertiary amine nitrogen groups in cellulose and every alkylene group introduced is connected to two quaternary ammonium ions. The products of this process have strong base anion exchange properties and fabrics of high nitrogen content are imparted both wet and dry crease resistance.

  • Patent number: 4063885
    Abstract: A single treatment process for imparting durable soil release and soil repellent properties to cotton fabrics and to cotton polyester blend fabrics with widely different constructions and compositions comprising free radical initiated reactions of a vinyl monomer that contains carboxyl functional groups with cotton and polyester in the fabrics, is described. Of special interest is the unusually high efficiency of removal of both aqueous soils and oily soils from the treated fabrics and the unusually high durability of the properties of treated cotton fabrics and cotton polyester blend fabrics with widely different constructions and compositions to laundering and cleaning.

  • Patent number: 4062841
    Abstract: Acetylthio amides and esters were prepared by the free radical addition of thiolacetic acid to the terminal and nonterminal double bonds of N-substituted fatty amides and fatty esters. The free radical additions of the thiolacetic acid to the unsaturated compounds were initiated by irradiation using cobalt-60. The process using irradiation with cobalt-60 was also used to bring about the addition of bromotrichloromethane to N-substituted fatty amides and fatty esters to produce halogen-containing amides and esters. These new sulfur or halogen-containing compounds were found to have antimicrobial activity and to possess properties making them useful as antimicrobial agents.

  • Patent number: 4061465
    Abstract: Cellulosic textiles are impregnated with an aqueous solution containing a methylol crosslinking reagent and either a half amide of a 1,2- or 1,3-dicarboxylic acid or a half ammonium, sodium, or potassium salt of a 1,2- or 1,3-dicarboxylic acid. After the impregnated textiles are cured, they have high levels of crosslinking as indicated by high resilience and high levels of acidic groups as indicated by basic dye adsorption and the ability to form new, permanent creases when pressed at high temperatures.

  • Patent number: 4055720
    Abstract: 2,4-Diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine were prepared by the reaction of the corresponding methyl or ethyl .gamma.-tribromo-butyrate or methyl or ethyl .gamma.-trichlorobutyrate with biguanide. The N-methylol derivatives of the diaminotrihalopropyl triazines were prepared by the reaction of the triazines with aqueous formaldehyde. Two pure tetramethylol derivatives were prepared, namely: 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazin e and 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazi ne. The tetramethylol derivatives were used to impart durable flame retardancy and wrinkle recovery to cellulosic textiles, particularly to cotton. Flame-retardancy was also imparted to wool and to blends of cotton and polyester.

  • Patent number: 4046953
    Abstract: 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.
