  • 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: 5490866
    Abstract: A process is disclosed for washing-off prints or dyeings produced with dyes on cellulosic textile materials, which comprises treating the printed or dyed fabrics in an aqueous wash liquor with a washing-off formulation comprising(a) a polyvinyl pyrrolidone homopolymer or copolymer, and(b) a water softener.The inventive process makes it possible to remove unfixed dye from the fibre material completely and thus to enhance the fastness properties of the dyeings.

  • 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: 5069919
    Abstract: A high yield process is provided for treating lignocellulose food fiber to sanitize and bleach the fiber. The process is not only a high yield process but produces better or equivalent bleaching than alternative processes and further does not produce a waste disposal problem. The process also has the advantage of requiring very little energy compared to alternative processes.

  • Patent number: 4834766
    Abstract: A method for preventing the adhesion of scale on the sealing mechanism of a high pressure steamer in a process of continuous scouring of a long cloth therein, which comprises washing the cloth to be subjected to scouring with the use of weak acidic water with a pH of 5-6 outside of the steamer body, passing the thus washed cloth through the sealing mechanism of the steamer body, and then applying a scouring agent solution to the cloth in the interior of the steamer body. A durable sealing mechanism can be offered by preventing the damage of the sealing mechanism.

  • Patent number: 4797128
    Abstract: Garments contaminated with radioactive, toxin, biological and/or chemical contaminants are deposited in a cleaning drum and the drum is agitated during a wash cycle. A dry cleaning solvent is added to the drum during the initial wash cycle and then drained to a distillation means. Within the distillation means, there is a neutralizing agent which deactivates the biological and toxin contaminants and chemically breaks down the chemical contaminants removed with the dry cleaning solvent from the cleaning drum. Dry cleaning solvent is then continuously added to the drum during the secondary wash cycle and continuously removed from the drum. After the dry cleaning solvent is removed from the drum, and before it is pumped back to the drum, the dry cleaning solvent is filtered to remove remaining trace particulate contaminants. The dry cleaning solvent is also passed through an absorber where remaining trace chemical contaminants dissolves in the dry cleaning solvent are removed.
