    摘要: This invention relates to a method of treating a surface with reagents. The method comprises:(i) establishing a reagent in a liquid phase;(ii) forming a foam of said liquid phase;(iii) applying said foam to said surface to be treated;(iv) causing or allowing the foam to collapse at the interface of said surface being treated to deposit the reagent thereon and thereafter removing or deactivating the reagent on said surface when the treatment is complete, whereby the rate of foam collapse is controlled to control the rate of application of the reagent to the said surface.

    摘要: A fibrous material is bleached by hydrogen peroxide in a weakly acidic state at a pH of 5-7, and then in a weakly alkaline state at a pH of 8.5-1.1 by adding an alkaline agent to the hydrogen peroxide by one whole charge or continuously after the bleaching in the weakly acidic state and utilizing the remaining hydrogen peroxide. The bleached fibrous material has a soft handling and a high whiteness, and no bleaching unevenness.

    摘要: A method of desizing, scouring and bleaching greige cotton/polyester fabrics containing colored portions constructed of yarns dyed with an excess of sensitive dyestuffs without incurring color markoff upon, or bleeding into the white background portions of the fabric. The dry greige fabric is first singed then quenched with steam or a water mist under conditions preventing a water pickup exceeding 30 percent of the fabric weight. The fabric is then passed through a multidip-type rope washer used as a treating chamber in which the solution contained therein is a hot alkaline solution of surface active agent held at 160*-210* F. and is at a solution to fabric weight ratio of 20-40:1. The motion of the fabric through the solution and alternate dipping and squeezing action of the solution through the fabric acts to scour, desize and remove excess dyestuff therefrom. After then washing thoroughly with water, the fabric is finally saturated with a peroxymonosulfate solution buffered at a pH of 5 to 8.5, then heated in the saturated condition at a temperature of 100*-212* F. to effect bleaching.

    摘要: A method for scouring and bleaching cotton fabric with composite enzyme preparation in one bath is provided. The method relates to the application of composite alkaline enzyme preparation in scouring and bleaching processes of cotton fabric. The enzyme preparation for scouring and bleaching cotton fabric is compounded from cutinase, alkaline pectase, alkaline xylanase, alkaline cellulose, and carbohydrate oxidase. The method includes: scouring the cotton fabric by adding the composite enzyme preparation, glucose, oxidation bleaching stabilizer RB-3, penetrant JFC, and Triton X-100 in a treating bath at 55-70° C. and pH 8-10, and then bleaching the cotton fabric for 30 min by directly adding tetraacetyl ethylenediamine (TAED) in the scouring bath to activate hydrogen peroxide. After being treated by the method of the present invention, the cotton fabric has high impurity removal ratio, favorable wettability, and high whiteness. The present invention has the advantages of low power consumption, short process flow, and being environment friendly, and may be used to replace conventional chemical treatment process under the condition of concentrated alkali and high temperature.
