  • Publication number: 20140057324
    Abstract: Variants of Bacillus sp. no. 707 alpha-amylase are provided that are produced more efficiently and thus more economically. Higher fermentation yields are achieved through introducing amino acid variations that promote solubility of the variant in a fermentation broth. Increased solubility allows more enzyme to remain in solution after expression in a host cell. This in turn increases the efficiency with which the expressed variant enzyme can be recovered from the fermentation broth.

    Abstract: Variants of B. licheniformis alpha-amylase advantageously exhibit improved enzymatic performance. Suitable variants include those with an altered charge distribution on the surface of the enzyme or with altered active site residues. Structural modeling can inform the choice of amino acid modifications so that modified amino acids correspond to residues found in more active alpha amylases, for example. Compositions comprising the variants are useful in methods of cleaning surfaces, laundering textiles, desizing, treating starch, e.g., liquefaction and saccharification, and hydrolyzing biofilms off various substrates.

  • Patent number: 6524349
    Abstract: A method for maintaining the hydrophobicity of a hydrophobic polyolefin textile material over time and use. The method includes providing a solution having a pH level between 3.5 and 5.9, subjecting the hydrophobic polyolefin textile material to the solution, and drying. The processed hydrophobic polyolefin textile material maintains hydrophobicity with a contact angle with water of at least 90 degrees permanently. The processed hydrophobic polyolefin fabric can be used in a monolayer or bilayer configuration. The processed hydrophobic polyolefin fabric improves the water vapor transfer through the processed fabric because the processed hydrophobic polyolefin fabric does not saturate, wick or swell with liquid perspiration thereby reducing water liquid attached to fabric pores which increases the volume of space for diffusion of perspiration vapor from the skin, through the fabric, to the outside ambient air. The result is a drier, more comfortable processed garment.

  • Patent number: 6036864
    Abstract: An economical process for reducing water consumption and, therefore, water discharge during the dyeing of textile goods is disclosed. Processing baths during dyeing, which can be reused directly or after minimal treatment, are segregated from baths which contain a high level of pollutants and color. The reuse baths are combined and stored separately from baths which are to be discharged. The reuse baths are then recycled directly or after minimal treatment to the dyeing process. Baths containing a high level of pollutants and color are either discharged directly to the local public treatment works or are treated in a conventional wastewater treatment plant. The process results in substantial economic benefits because the operating costs of recycling reuse baths are low and because the quantity of wastewater discharged is substantially reduced.

  • Patent number: 5334224
    Abstract: A method for the pretreatment of a long cloth continuously in which a cloth to be subjected to desizing, scouring and bleaching for the pretreatment thereof is preliminarily subjected to souring treatment in the sodium chlorite solution prepared by absorbing the chlorine dioxide gas, which is exhausted from the subsequent bleaching process with the use of chlorite, in a solution of H.sub.2 O.sub.2 and NaOH, and accordingly it is possible to transport the long cloth continuously in the pretreating process speedily with no need of staying the cloth in folded state for increasing the productivity and improving the quality of the product, and further to render the pretreating apparatus compact so as suitable for the production of small lot products.

  • Patent number: 5331773
    Abstract: The machine for the superficial abrasive treatment of fabrics comprises means (B1, B2, 1, 3, 5, 7, 9, 11) for feeding the fabric (T) for treatment and for pressing said fabric against an abrasive means (29; 51) which exerts an abrasive action on said fabric. The abrasive means comprises one or more blocks (33, 34, 35, 36; 51) of a natural, artificial or synthetic cellular or honeycombed abrasive material; the relative velocity between the active surface of the abrasive means and the fabric is between 10 and 60 m/min.

  • Patent number: 5234463
    Abstract: A method for desizing and scouring of a long length of cloth comprising desizing a cloth washed with hot water, and then subjecting the cloth thus washed successively to soaking with a hot alkaline sodium chlorite solution, immersing in a hot acid solution with a pH of 2-4, then to soaking with a caustic soda solution, and finally to the wet heat treatment under the ordinary pressure.

  • Patent number: 4712290
    Abstract: Yarn to be utilized for the manufacture of pre-softened fabric is stiffened without the use of binding agents. Only corn starch and low temperature wax are utilized as stiffeners. Fabric manufactured from such yarn is then subjected to a finishing process, in which enzymes capable of breaking down the corn starch and a wetter/rewetter are added to the fabric itself. These enzymes are activated during a subsequent soaking in water only, followed by agitation, whereby stiffness may be removed from the fabric in approximately 5 minutes. In accordance with another aspect of the invention, softeners are also added to the fabric during the finishing process. The softeners are also released during the subsequent garment washing operation. Preferably, the softeners include at least reactive silicon. This serves the additional purpose of lubricating sewing needles and cutting knives during the garment manufacturing process.

  • Patent number: 4624675
    Abstract: A process for producing a woven cotton fabric wherein the warp is treated with water-soluble cold size. A pile warp, if present, is sized after warping. After weaving, the size is washed out with soda and a decalcifying agent. By rinsing twice, the dissolved size, lime and soda residues are removed. Drying is effected on a tenter frame, with or without shrinking. The process produces a fabric wherein the cotton fibers retain many of their natural properties.
