摘要:
An acrylonitrile-containing fiber includes 100 parts by mass of a polymer including at least 15 parts by mass of acrylonitrile; and 1.0 to 50 parts by mass of a water absorbent resin having a pure water absorption capacity (g/g) with respect to its own weight of at least 10 but less than 100, wherein the fiber is dyeable with a disperse dye.
摘要:
The present invention relates to a process for continuous dyeing of filaments based on atactic polyvinyl chloride in the course of production.It comprises, in succession, the phases of drawing, impregnation of the filaments by padding while, at the time of the impregnation, the filaments have a density of between 1.3 and 1.4 g/cm.sup.3 (the filament roving having a water content of 10 to 30% by weight), of stabilization under tension in the presence of steam under pressure at a temperature between 100.degree. and 130.degree. C. for 2 to 20 seconds, and then oiling and shrinking in a known manner.Dyeing carried out in this manner is quick and makes it possible to produce colors having good fastness.

A hydrophobic fiber material is dyed in a dye bath containing at least nine disperse dyes having different chemical structures from one another within a short period of time with a good levelness.
摘要:
Process for dyeing materials which contain synthetic fibres with dyes that are sparingly soluble to insoluble in water, in the presence of dyeing auxiliaries which are polyadducts of propylene oxide and a polyhydric aliphatic alcohol of at least 2 carbon atoms, wherein said adducts are soluble in water and contain sulphonic acid groups.The process of present invention is especially suitable for dyeing linear polyester fibres wherein level and strong dyeings are obtained which are in addition characterized by good fastness to rubbing.
摘要:
Basic azo dyes are made by coupling an appropriate diazotized benzenoid or heterocyclic base with an N-dialkylaminoalkylene ( Alpha (N-alkylanilino))m- or p-toluenesulfonamide. Quarternization of the pendant dialkylamino group in the coupler may be carried out before or after coupling if desired to yield quaternary structures. The unquaternized structures, when properly dispersed, are applied to polyesters with excellent substantivity, outstanding fastness to sublimation and good fastness to light. The disperse unquaternized dyes are applied to polyacrylonitrile fabrics from a neutral or acidic bath; the water soluble quaternary structures are especially useful for coloring acrylic fibers.
WHEREIN M stands for a divalent radical, W for the nitro group or for an amino group, K e.g. for an ammonium-, hydrazinium- or an amminogroup, A for an anion and wherein the ring B and/or D may be further substituted. They can be used for the dyeing of acrylonitrile polymers or copolymers.

摘要:
Heterocyclic disazo compounds containing two heterocyclicazoaniline groups of general formula WHERE D is a heterocyclic diazo component such as thiazolyl, benzthiazolyl, benzimidazolyl, etc. C AND D ARE SUCH SUBSTITUENTS AS METHYL, ETHOXY, PHENOXY AND ACYLAMINO R1 can be hydrogen, lower alkyl and lower alkyl substituted by cyano, phenyl, hydroxy, alkoxy, etc. R3 can be alkylene and substituted alkylene, etc. are bridged by a bridging group, Z, which has no dyestuff characteristics, such as -O-R5-O-, -NH-R5-NH- where R5 is aliphatic, cyclo- or araliphatic, aromatic or acyl, WHERE X'' is oxygen, sulfur or -NH and R6 is aliphatic, cycloaliphatic, aromatic or heterocyclic. The compounds are useful in dyeing synthetic fibers, especially polyester and acrylic.
