Condensation products of complex copper compounds with nitrogen-containing compounds and aldehydes

The wet-fastness of dyeings and prints made with water-soluble substantive dyestuffs on cellulose fibres is enhanced by treating them with an aqueous solution of a resin made by condensing an aldehyde, a complex copper salt and a compound of the urea family containing at least once the grouping <FORM:0736792/IV (c)/1> The condensation may be performed in presence of an ammonium salt, an amine or an amine salt.

Cellulose/synthetic fibre mixts - simultaneous dyeing and making water-repellant

Piece goods of cellulose fibres mixed with synthetic fibres, pref. polyester fibres are simultaneously coloured and made hydrophobic by impregnation of the textile material at room temp. with an aq. dye liquor which in addn. to reactive dyes and dispersion dyes contains heat-condensable or fibre-philic agent for making hydrophobic and possibly catalysts necessary for the condensation, a protective colloid and possibly a heat active alkali spender. The treated articles are dried, then undergo a thermal treatment for fixing of the dispersion dye as well as for condsn of the hydrophobing agent using dry heat at 140-210 degrees C. Finally the fixing of the reactive dye is carried out by the wet-fixing method. This single bath treatment is cheaper than previous processes.

Printing pastes for cellulose textiles - contg reactive dyes,aminoplast resins and thickeners without reactive hydrogen

The printing pastes have a pH of 4.5 - 7.5 and contain thickeners with no reactive H to react with the aminoplast resins present. Suitable thickeners are synthetic polymers, esp. copolymers from maleic anhydride and vinyl isobutyl ether, lightly cross-linked with hexamethylene diamine, or alkali salts of polyacrylic acid opt. lightly cross-linked e.g. with divinyl dioxane.

Fibers containing marker compositions and cross-linked polymers

Fibers and other articles of manufacture have a near-infrared fluorescent compositions, useful as identification markers, attached to the fiber or article of manufacture by a cross-linking agent. The marker compositions may contain other ingredients, such as antistats, antimicrobials and/or other additives mixed therein. Effective cross-linking can be obtained by several means, including heating in an oven, air-drying, etc. A method for marking the fiber or article includes contacting the material with a cross-linking agent and a near-infrared fluorescing compound having an absorbance of illumination radiation ranging from about 650 nm to about 100 nm.

Process to improve resistance to stains on fibres and derived products

The invention consists of a process to improve the resistance to stains on f ibres, processed or not, finished or not on the basis of dyeable natural or synthetic fibres, in particular polyamide. According to t he invention the fibres are treated with a solution cont aining tannic acid and a condensation product of a sulphonated phenol- or naphtol-d erivate with an aldehyde. The treatment can be made befo re, during or after the dyeing process. The treatment is done in an acid medium.

Production process of all-cotton flannel printed fabric

本发明涉及法兰绒面料生产工艺技术领域，特别是涉及一种全棉法兰绒印花面料的生产工艺，包括：将全棉21s纱线和粗梳毛纱分别通过固酸、固色和干燥后得到预处理的全棉21s纱线和预处理的粗梳毛纱；再通过两上两下左斜斜纹织造法进行织造，得到织造后的面料待用；将织造后的面料放入印花浆中进行印花处理，再经过水洗、脱水和烘干定型，即得。本发明解决现有技术中全棉法兰绒面料易掉色的问题；将全棉21s纱线和粗梳毛纱进行预处理后更容易上色，上色后不容易掉色，色牢度更高；通过活性印花工艺进行生产，印花浆中的活性成分更好进入纤维中，从而提高色牢度。
