    Abstract: A process for the flame-retardant treatment of a cellulosic fabric by impregnating a fabric with an aqueous solution of a tetrakis (hydroxyorgano) phosphonium (THP) and then at least partially drying it. The partially dried impregnated fabric is passed at a speed of 30 to 100 m/minute once through a chamber containing ammonia for a single cure. Both the moisture contained in the fabric and water produced as a by-product of curing are volatilized and condensed on an interior wall of the chamber and flow down the walls to a drain for removal of the condensed water from the apparatus. The process further includes measuring the rate of ammonia in the gas fed into the chamber, determining the ammonia content of the gas and measuring the temperature within the chamber, for maintaining the initial concentration of ammonia in the gas at 70% to 90% by volume and for maintaining the ratio of ammonia input to the THP composition in the range of at least 1.

  • Patent number: 5837009
    Abstract: A method for cotton purification is described, where the cotton is subject to a purification process in water. The process solution contains calcium hydroxide and a non-ionic detergent wetting agent. Following this processing the cotton is rendered hydrophilic. The cotton is carried in a net with simultaneous removal of the adsorbed processing solution. It is then washed and bleached with H.sub.2 O.sub.2 or ClONa in a two-stage process. The effluent water is processed by anaerobic digestion in the thermophilic region for the production of biogas. The effluent water from the anaerobic digestion process is further processed by aerobic biological treatment. The whole process operates with energy self-sufficiency without resulting in environment pollution. Finally, a high purity cotton is produced with high water absorptivity which is suitable for spinning for the production of quality cotton yarns suitable for weaving quality fabrics or dyeing.

  • Patent number: 5817155
    Abstract: An emulsion for hair treatment is provided which is characterized by the following: the formulation (I) is composed of a W/O type emulsion, which allows the main agent to be stable, and contains preferably an oil soluble polymer compound for the emulsifier; the formulation (I), upon being mixed with formulation (II), can easily undergo demulsification and a phase inversion into an O/W type emulsion; and the emulsion has adequate viscosity to prevent dripping from the hair and a superior dyeing capability. Also, 2-formulation type oxidation hair dye with an excellent hair dyeing effect is provided by adding isostearyl alcohol.

  • Patent number: 5792218
    Abstract: Nitrile activators, such as N-alkyl ammonium acetonitrile activators, are combined with a source of active oxygen as cleaning and bleaching compositions. Preferred activator embodiments of the invention include salts of N-methyl morpholinium acetonitrile, N-butyl morpholinium acetonitrile, N-hexyl morpholinium acetonitrile, and N-octyl morpholinium acetonitrile. A particularly preferred activator embodiment is an N-methyl morpholinium acetonitrile salt. The nitrile and active oxygen react to form a bleaching agent which is applied to a stain on an article. The treated stain is contacted with dense gas so as to provide substantially non-aqueous stain removal. One embodiment is a composition in which the nitrile and active oxygen are disposed in the dense carbon dioxide.

  • Patent number: 5785886
    Abstract: A bleach system is described that includes a peroxygen compound which is hydrogen peroxide or an inorganic substance that generates hydrogen peroxide in water, a C.sub.1 -C.sub.30 imine and a transition metal catalyst. Use of the transition metal catalyst promotes the interaction of the hydrogen peroxide and imine thereby enhancing bleach performance.

  • Patent number: 5783175
    Abstract: The invention relates to substantially dust-free bleach powders that, when mixed with aqueous hydrogen peroxide, yield activated bleach compositions that exhibit improved thixotropy. The bleach powders comprise at least one de-dusting agent and at least one peroxygenated salt. The de-dusting agents, which are preferably present in an amount less than about 10% by weight of the bleach powder are inert, substantially hydrophilic compounds selected from alkylated esters, cyclic ethers and cyclic esters. The bleach powders also comprise powdered polytetrafluoroethylene (PTFE) in an amount of about 1-5% by weight of the bleach powder. The bleach powders also comprise an ammonia source, e.g., an ammonium halide, diammonium phosphate, ammonium sulfate and mixtures thereof. Optionally, one or more hair conditioning agents, thickeners and desiccants may be added to the dust-free bleach powder.

  • Patent number: 5763382
    Abstract: A cold water washing formula and a method of reducing the soil load on a textile by introducing the textile and cold water into an internal assembly within a washing machine. The method includes a first break wash wherein the textile, water, and a solvent are introduced into the washing machine to initiate soil removal. In a second break wash, a surfactant and an alkali are added to the first break wash to continue the washing cycle. The combined first and second break washes are drained from the internal assembly and the textile is rinsed with water. After draining the first rinse from the internal assembly, a second rinse including ozonated water and an acid is introduced into the internal assembly. The second rinse is drained from the internal assembly and a third rinse, which includes ozonated water, is introduced into the internal assembly to rinse the textile.
