Abstract: A system for ammoniating and curing flame-retardant impregnated single textile yarns by steps including impregnating the yarn with THPOH, drying the impregnated yarn, and ammoniating the THPOH-impregnated yarn by passing a single end of the yarn through a small tube leading into an ammoniation chamber wherein there is located a spool and means for rotating said spool for winding the ammoniated yarn onto the spool, the small tube being reciprocatable to traverse the length of the spool for uniformly winding the yarn on the spool.
Abstract: Heat Transfer prints are made by offset printing using a UV curable ink containing subliminal dyes printed onto a heat transfer backing, followed by rapid curing using UV light. The heat transfer prints are then used for dying fabric by applying the heat transfer print to the fabric, heating the print and thereby causing the dyes to sublimate and thereby transfer from the heat transfer print to the fabric where dying of the fabric occurs.
Abstract: Fast colorations can be obtained on cellulose materials with disperse dyestuffs containing ester groups when heat-fixation occurs in the presence of aliphatic alcohols, amines or aminoalcohols. Probably a transesterification and/or amide formation leading to significantly higher molecular weight of the dyestuffs are responsible for the good fastness properties of the colorations.
Abstract: This invention pertains to transfer sheets which comprise a flexible nontextile substrate in sheet, roll or web form having an all-over or discontinuous printed pattern effect thereon with the pattern being formed by a film of a dried ink formulation adapted for heat transfer printing of synthetic textiles in which the ink contains a red azo acylanilide of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which are the same or different, are alkyl. These transfer sheets can be used for the heat transfer printing of synthetic textile fibers such polyester textile fibers and nylon textile fibers.
Abstract: The invention relates to the use of the dye of the formula ##STR1## for transfer printing, and to printing inks and supports for transfer printing which contain, in addition to the customary constituents, the dye of the indicated formula, as well as to the material printed with the dye.
Abstract: A process for printing flat-surface structures of manmade or regenerated polymer materials by the transfer printing process, which comprises the use of dyes of the formula ##STR1## wherein X represents hydrogen, halogen, or a lower alkylsulphone group,Y represents hydrogen, chlorine, bromine, nitro, cyano, or an alkyl group of 1 to 4 carbon atoms,Z represents hydrogen, chlorine, nitro, an acylamino group, or a lower alkylsulphonyl group,R represents an alkyl radical of 1 to 4 carbon atoms, andR.sub.1, R.sub.2 and R.sub.3, each independently of the other, represent an alkyl radical of 1 to 4 carbon atoms, a cycloalkyl radical of 5 to 7 carbon atoms, an aralkyl or an aryl radical.
Abstract: The invention relates to the use of the dye of the formula ##STR1## for transfer printing, and to printing inks and supports for transfer printing which contain, in addition to the customary constituents, the dye of the indicated formula, as well as to the material printed with the dye.
