    摘要: The invention relates to a process for increasing the dyeability of textile fibers and fabrics without the need to use a salt in the dyebath. The dyeing is performed on fibers or fabrics which have been treated with sodium hydroxide and an epoxy ammonium salt of the formula: ##STR1## wherein R,R',R", and R"' are alkyl radicals having 1 to 8 carbon atoms, and X.sup.- is an anionic group selected from the group consisting of sulfate, sulfonate and halide.

    摘要: The invention relates to a process for increasing the dyeability of textile fibers and fabrics without the need to use a salt in the dyebath. The dyeing is performed on fibers or fabrics which have been treated with potassium hydroxide and an epoxy ammonium salt of the formula: ##STR1## wherein R, R', R", and R'" are alkyl radicals having 1 to 8 carbon atoms, and X.sup.- is an anionic group selected from the group consisting of sulfate, sulfonate and halide.

    摘要: A first yarn (21) undergoes a pretreatment process (22) for saturation with a pretreatment solution. In the pretreatment process, the first yarn is supplied to continuously travel through a first bath (100.sub.2) and a second bath (100.sub.3) of the pretreatment solution. The first bath has a volume (V.sub.2) which is less than a volume of the second bath (V.sub.3). Between the first and second baths the pretreatment solution is impressed into the continuously moving first yarn. After the second bath only excess pretreatment solution is removed from the moving yarn, thereby keeping the yarn saturated when it enters a heat treatment (42) for locking the pretreatment solution into the yarn. The first yarn can be subsequently dyed in the same operation or maintain its original appearance (either colored or non-colored). The first yarn can be a warp yarn or weft yarn which, together with either a second yarn (weft or warp yarn, treated or untreated), is woven into a fabric piece (26). Either the fabric piece, or a textile article (28) formed therefrom, is then introduced into a subsequent, specialized dyeing process (30). In the specialized dyeing process, an anionic type dye (such as a direct, fiber-reactive, etc. type dye) is attracted only to the pretreated yarn, so that only the pretreated yarn is colored (dyed or tinted) and the untreated yarn is substantially unchanged.
