摘要:
A cutting and double-face leather integrated dyeing process for Tan sheep skin, which comprises the following steps: cutting→washing with water→retanning→primary dyeing→primary color fixing→secondary dyeing→fatliquoring→secondary color fixing→bleaching→drying→a finished product. Tan sheep skin leather boards and fleeces dyed by the process of the invention have no cross color and color fading with each other, a high color fastness, and uniform dyeing; the prepared Tan sheep skin products such as clothing, etc., not only have the characteristics of a high added value and good practicability, but also can more largely increase product benefits and lower the production cost.
摘要:
Composite particulates, topical composition containing composite particulates, methods for improving the appearance of skin depth, dimensionality or undertones; a method for improving the ashy, chalky or mask-like appearance of color cosmetic compositions on the skin; and a method for reducing the number of shades in a color cosmetic shade range by formulating the cosmetic with composite particulates.
摘要:
Disclosed is composition comprising an aqueous dispersion containing a dye, a stain blocker component, and an anti-soil component. The composition provides uniform dyeing, and superior stain blocking and anti-soil characteristics to fibers, carpets, and fabrics by adjusting the conductivity and pH of the dispersion. Alternatively, the composition can comprise an aqueous dispersion containing a dye, a stain blocker component, and a retarder for slowing down the rate of dye reaction. Also disclosed is a method of applying the compositions and dispersions to fibers, carpets, and fabrics.
摘要:
Provided are compounds and methods for modifying a material to change properties of the material, as well as a variety of products obtained using the methods. In one embodiment, a material comprising one or more modifiable functional groups is reacted with an activated hydrophobic acyl group in the presence of a hindered base, thereby to covalently attach the hydrophobic acyl group to the modifiable functional groups on the material. The material which is modified may be, for example, a carbohydrate, and the modifiable functional groups on the material may be hydroxyls. For example, materials such as cellulose may be modified by reacting it with an acid chloride or acid anhydride including a hydrophobic acyl group, in the presence of a hindered base, such as tripentylamine, to attach the hydrophobic acyl groups to the hydroxyls on the cellulose, thereby to increase the hydrophobicity of the cellulose. The methods and compounds disclosed herein may be used to modify materials to improve properties such as resistance, grease repellency, soil resistance and permanent press properties.

Provided are compounds and methods for modifying a material to change properties of the material, as well as a variety of products obtained using the methods. The material which is modified may be, for example, a carbohydrate, and the modifiable functional groups on the material may be hydroxyls. Multifunctional molecules for use in modifying the surfaces of materials such as textile fibers, yams and other fabrics made of or, including cotton, wool and nylon, are provided. The multifunctional molecules can include hydrophobic regions and/or hydrophilic regions. The multifunctional molecules also may include binding functional groups that permit either non-covalent or covalent binding to the material being modified, thus permitting the multifunctional molecule to form a non-covalent or covalent coating on the material. The methods and compounds disclosed herein may be used to modify materials to improve properties such as resistance, grease repellency, soil resistance permanent press properties, and quickness of drying.
摘要:
Textile materials having high colorfastness, and methods for their production are described. The process involves heatsetting a textile material, then applying a polysiloxane/catalyst combination to the heatset material. The textile material is then dried at low temperature, thereby resulting in a material having good colorfastness and shade. The process can be used to process fibers, yarns or fabrics, and is particularly useful in the processing of microdenier fibers.

The present invention relates to a process for providing a bleached look in the color density of the surface of dyed fabric, especially cellulosic fabric such as denim, comprising use of a phenol oxidizing enzyme such as a peroxidase or a laccase, a hydrogen peroxide source and an enhancing agent represented by formula (I). ##STR1##
摘要:
Dyed or printed synthetic fibers or materials consisting of synthetic fibers or of a mixture of synthetic fibers with other fibers are aftertreated with aqueous solutions which contain from 0.2 to 20 g/l of a mixture of one or more surfactants and a reductonate. The pH of the liquor is brought to above 8 and the aftertreatment is carried out at from 40.degree. to 100.degree. C.
摘要:
A process for aftertreating dyed textile material consisting of or containing polyester fibres and thus preventing oligomer deposits on the dyeings, which process comprises treating said textile material at a temperature below the glass transition point of the polyester fibres with an aqueous emulsion of an oligomer-dissolving substance which consists of(a) an ester of an aliphatic or aromatic carboxylic acid with an aliphatic or araliphatic monoalcohol containing 1 to 10 carbon atoms,(b) an aliphatic or aromatic halogenated hydrocarbon,(c) a non-ionic adduct of not more than 10 moles of alkylene oxide with alcohols, fatty acids or amines, each containing 8 to 22 carbon atoms, or with phenols which can be substituted by alkyl or phenyl, the cloud point of said adduct being below the application temperature, or(d) a polyethylene oxide/polypropylene oxide block polymer, the hydrophobic polyoxypropylene moiety of which has a molecular weight of 800 to 4000, and the hydrophilic moiety of the entire molecule is from 10 to 35% by weight, the cloud point of said block polymer being below the application temperature,Or which consists of a mixture of said substances (a), (b), (c) and (d).
