  • Publication number: 20090311931
    Abstract: The invention is related to mild pretreatment or preparation process as well as combined scoring and bleaching composition for cellulose-based textile material. The process comprises a sequential or simultaneous scouring step with an enzyme composition acting on the non-cellulosic material on outer layers of cellulosic fibers and a reducing bleaching step with a reducing bleaching agent. The reducing bleaching agent is preferably dithionite. In the process no adjustment of pH and temperature are required. The process is environmentally friendly because no causticizing and oxidizing agents are required to achieve the desired lightness and wettability. Due to the mild pretreatment conditions tensile strength of the fabric is better than that achieved with conventional pretreatments.

  • Patent number: 6599326
    Abstract: Chemical pulps or papers, especially kraft pulps or papers, which may still contain traces of lignin, have enhanced resistance to yellowing when they contain an effective stabilizing amount of a N,N-dialkylhydroxylamine, an ester, amide or thio substituted N,N-dialkylhydroxylamine or N,N-dibenzylhydroxylamine or an amminium salt thereof. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective. N,N-Diethylhydroxylamine and N,N-dibenzylhydroxylamine and their acid salts are surprisingly effective for this purpose.

The decolorizing composition for fibers dyed with an oxidation hair dye composition and/or direct-dyeing hair dye compounds contains a combination of one or more .alpha.-oxo-carboxylic acids and/or physiologically compatible .alpha.-oxocarboxylic acid salts with at least one reductone, or with at least one reductone and at least one thiol compound, or with at least one reductone and at least one sulfite compound, or with at least one reductone and at least one thiol compound and at least one sulfite compound. A multi-part kit for repeatedly dyeing and subsequently decolorizing fibers, especially human hair, contains both a dye composition for dyeing the fibers and the above-described composition for reductive decolorizing of the dyed fibers.

  • Patent number: 5688291
    Abstract: In accordance with the present invention, there is provided a single-step process and composition of a category-2 hair bleach which can simultaneously lighten the hair up to seven levels, and effectively neutralize any undesirable warmth that accompanies the lightening process. This is achieved by including in the bleach composition disperse dye molecules which the present invention has found to be both, stable in the bleach, and capable of depositing the desired amount of various permanent tones on the hair. These disperse dyes do not stain the scalp of the client or the hands of the hairdresser, but are substantive only to the hair fibers. The dyes fall into the classes of anthraquinones and azo compounds.
