摘要:
A process for dyeing textile fiber materials with water-soluble dyestuffs, in particular anionic dyestuffs, and of these in particular those having a fiber-reactive group, in which the dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye liquors or printing pastes and a fiber material which has been modified with a silane compound containing amino groups is used as the textile material. The fiber material is modified by applying the silane compound containing amino groups to the material in aqueous solution and subjecting the impregnated material to a heat treatment. Novel silane compounds which contain a secondary amino group and can likewise be employed for the purpose mentioned are furthermore described.

Buttons or similar products in vegetable ivory undergo a first base dyeing, are then covered in preset areas with a temporary protecting film, and submitted to a second dyeing; the protecting film is eventually removed to obtain a multicolor product.
摘要:
An elastic warp knitted fabric having a pulling out force for pulling out an elastic yarn from the knitted fabric of 30 g or more, and in which a shape of a sinker loop of a nonelastic yarn is maintained as a bulge shape after an application of a dyeing and finishing treatment. This elastic warp knitted fabric can be manufactured by using a specially prepared dyeing and finishing treatment, so that the sinker loop of the nonelastic yarn can be maintained in the treatment.
摘要:
A method for tinting a water-absorptive contact lens to have a mark tinted thereon, which comprises superimposing on a water-absorptive contact lens in the dry state a screen provided with a tinting pattern corresponding to the mark to be tinted on the contact lens, applying to the contact lens through the tinting pattern of the screen a dye solution containing a vat dye and an alkaline reducing agent, followed by insolubilizing the vat dye.

3-Substituted para-aminophenols of general formula: ##STR1## where X.dbd.H, halogen; Y.dbd.O--, --S--; R.dbd.alkyl, hydroxyalkyl, C.sub.1-4 aminoalkyl or C.sub.3 -C.sub.6 polyhydroxyalkyl;with the proviso that, when X.dbd.H, R is not methyl, and when X.dbd.H and Y.dbd.O, R is not ethyl;process for preparing them, intermediate compounds of formula: ##STR2## where X.sub.1 =halogen, Y and R have the meaning stated above; with the proviso that, when Y.dbd.O, R is not methyl, and when R=aminoalkyl, X.sub.1 can also denote hydrogen;dyeing compositions containing one or more compounds of formula (I), and a process for dyeing human hair.
摘要:
A method of producing a dyed polysaccharide which comprises linking a dye, capable of linking to amino group or imino group, to a starch derivative having a glucose derivative unit shown in a general formula [I] as a partial structure of the starch derivative. ##STR1## In the formula [I], R represents an arylene group or an alkylene group, R.sub.1, represents hydrogen atom or an alkyl group, and X and Y represent linking portions to other portions of the starch molecule, respectively.According to the method of the invention, dyed polysaccharides can readily be obtained by using a commercial reactive dye at room temperature under neutral conditions.
摘要:
A process for coloring hair in which a functional metal ion and aminoalkyl or aminohydroxyalkyl catechols are used in combination or applied sequentially to dye the hair rapidly.
摘要:
A composition for coloring bait which comprises (a) at least one biologically acceptable and palatable colorant; (b) a mordant for binding said colorant to live bait; (c) a surfactant or an acidulant; and (d) an aqueous carrier. A kit for coloring live bait to catch fish comprising (a), (b) and (c) of the composition also forms part of the invention.
摘要:
The invention relates to reactive dyes of the formula ##STR1## wherein D is the radical of a dye of the monoazo or polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide series, each of R.sub.1 and R.sub.2 independently is hydrogen or an unsubstituted or substituted C.sub.1 -C.sub.4 alkyl radical, X.sub.1 is an unsubstituted or substituted aminofluoro-s-triazine radical, and X.sub.2 is a heterocyclic reactive radical which is attached direct to the radical D through the --N(R.sub.2) bridge member, excepting an unsubstituted or substituted aminofluoro-s-triazine.These dyes are particularly suitable for dyeing and printing cellulosic fibre material by the cold pad-batch method and give dyeings and prints of good fastness properties and high tinctorial strength.
