    • A first yarn (21) undergoes a pretreatment process (22) for saturation with a pretreatment solution. In the pretreatment process, the first yarn continuously travels through a first bath (100) and a second bath (100) of the pretreatment solution. Between the first and second baths the pretreatment solution is impressed into the continuously moving first yarn. After the second bath excess pretreatment solution is removed from the yarn, 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. The first yarn together with a second yarn is woven into a fabric piece (26). Either the fabric piece, or a textile article (28) formed therefrom, is introduced into a dyeing process (30). In the dyeing process, an anionic type dye is attracted only to the pretreated yarn so that only the pretreated yarn is colored and the untreated yarn is substantially unchanged.
    • 第一纱线(21)经受预处理工艺(22)以用预处理溶液饱和。 在预处理过程中,第一纱线连续地穿过预处理溶液的第一浴(100)和第二浴(100)。 在第一和第二浴之间,将预处理溶液压入连续移动的第一纱线中。 在从纱线中除去第二槽过量预处理溶液之后,当进入用于将预处理溶液锁定到纱线中的热处理(42)时,保持纱线饱和。 第一条纱可以随后在相同的操作中染色或保持其原始外观。 将第一纱线与第二纱线一起编织成织物片(26)。 将织物片或由其形成的织物(28)引入染色过程(30)中。 在染色过程中,阴离子型染料仅被吸收到预处理的纱线上,使得仅预处理的纱线着色并且未处理纱线基本上不变。
