摘要:
A process for the production of aminated cotton fibers by subjecting a raw cotton or cotton-polyester mixture to a modification with a saturated aliphatic compound of 3 to 15 carbon atoms which contains at least one primary, secondary, tertiary, or quaternary amino group and at least one hydrolyzable ester group, in which the saturated radical is straight chain, branched, or cyclic, and may be interrupted by one or more hetero groups and may be substituted by one or more hydroxyl groups. The modification occurs simultaneously with scouring, kiering, or dry mercerizing.
摘要:
Fiber materials are modified with a polyalkyleneimine polymer at crosslinking agent, preferably glyoxal, and optionally dyed with water-soluble, anionic dyes, preferably reactive dyes. The dyeing process with fiber materials modified according to the invention can be carried out low-salt or completely without salt and also alkali-free or using only minimal amounts of alkali.
摘要:
The present invention relates to dyes of the formula (I), in which R1 to R4, D1, f, and M are defined as indicated in claim 1, to processes for preparing them, and to their use for dyeing and printing hydroxyl- and/or carboxamido-containing materials.
摘要:
Disclosed are aminated acetate fiber comprising acetylcellulose and one or more water-insoluble quaternary starch ether esters, said starch ether esters containing ester groups of formulae --O--CO--CH.sub.3 and/or --O--CO--C.sub.2 H.sub.5 and ether groups of the general formula I--O--CH.sub.2 --X--CH.sub.2 --N.sup.+ R.sub.3 A.sup.- (I)whereX is a direct bond or --CH(OH)-- andA.sup.- is an anion or one equivalent of an anion, andR is hydrogen, methyl and/or ethyl,and the degree of substitution of said ether group being within the range from 0.002 to 0.8, the degree of substitution of said ester group being within the range from 0.7 to 2.998 and the overall degree of substitution being within the range from 1.5 to 3, its preparation and its use and also quaternary starch ether esters present therein.
摘要:
Cellullosic textile materials are dyed by a pad or spraying process using a solution which contains 5-100 g/l of inorganic polyphosphate and has a pH of 10-13.5.
摘要:
Process for dyeing regenerated cellulose fibers, which comprises adding an amine-substituted cellulose derivative to a viscose dope or to an alkali cellulose and spinning fibers by the viscose spinning process, or adding said cellulose derivative to a cellulose solution and spinning fibers from the solution, processing fibers into a woven or knitted fabric and dyeing the fabric with a direct or acid dye in the absence of additional electrolyte salt.
摘要:
Aqueous ink formulation and a process for printing sheetlike cellulose fiber materials or materials containing cellulose fibers with reactive dyes using a single-phase inkjet process or some other non-contact minimal addon spray technique and subsequent fixation of the reactive dyes on the fiber, which comprises using an aqueous ink formulation comprising an alkali metal fluoride, an alkali metal formate, an alkali metal citrate, an alkali metal salt of a C.sub.2 -C.sub.4 -dicarboxylic acid or a mixture thereof.
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.
