摘要:
Process for preparing on textile materials consisting of polyamide fibres or of their mixtures with cellulose fibres, or containing such fibres or fibre blends, prints and pad-dyeings having extremely good fastnesses to wet processing, using reactive dyestuffs for printing and padding, and fixing these dyestuffs by steaming at a pH range of from about 6 to 11, preferably of from 7 to 8.5.

WHEREIN X IS ZERO OR A NUMBER OF FROM 1 TO 4, ARE USED AS FIXING AUXILIARIES. The prints which are prepared by using these fixing auxiliaries are distinguished by a good to excellent dyestuff yield with brilliant shades, they have a good to very good fastness to light and to use required for textile materials. Furthermore, the fixing auxiliaries facilitate the elimination of the carriers also used by their emulsifying properties in the usual aftertreatments of dyeings and prints by rinsing, so that the shades are protected from being spoiled and the fastness to light is increased.
A process for printing and continuously fixing prints of disperse dyestuffs on fibrous materials of polyester, cellulosetriacetate and cellulose-2 1/2 -acetate and mixtures thereof or mixtures with wool, natural or regenerated cellulose fibers or with other synthetic fibers, wherein compounds of the formula (1) R1-CO-(OC2H4)n-O-C4H8-O-(C2H4O)m-OC-R2(1) wherein R1-CO- and R2-CO- each represents the acyl radicals of linear or branched alkane- or alkene monocarboxylic acids with from 12 to 22 carbon atoms and n and m each is a number of from 4 to 12, alone, or in combination with oxethylated naphtols of the formula (2)
摘要:
A process for printing and continuous fixation of stabilized dyeing preparations forming azo dyestuffs and of reactive dyestuffs on textile materials containing cellulose or consisting exclusively of cellulose material, comprising a continuous working process of steaming the material printed with the dyeing preparations and reactive dyestuffs, for a short time for developing and fixing the azo dyestuffs using high concentrations of volatile acids with or without use of a counter-current operation method, and of treating then the material according to a known two-phase-fixation process for fixing the reactive dyestuffs and finishing it as usual by washing, soaping and rinsing as well as a process comprising the said very rapid fixation process of stabilized dyeing preparations forming azo dystuffs, by means of acid steam except for the use of reactive dyestuffs and for the use of the two-phase-fixation process which leads to dyeings of azo dyestuffs and of reactive dyestuffs of good fastenesses and brilliancy obtained in a very short time by means of a fully continuous process of fixing azo and reactive dyestuffs and of after-treatment the dyed material.
摘要:
The present disclosure is directed to a process and apparatus for the heat-treatment of textile materials, particularly those materials which are only slightly or not permeable to air when in a wet condition. More particularly, the present disclosure is directed to a process and apparatus for producing a steam cushion at the surface of the material being treated, said material being conveyed on the surface of sieve drum means.
