Process for the manufacture of a dyed sheet-like textile structure

A process for the manufacture of a uniformly dyed textile web selected from woven and non-woven fibrous materials intended for subsequent making-up into garments adapted to have a non-uniformly worn and faded appearance, those areas which are exposed to a greater degree of wear having a lighter color, comprising the steps of:

• 1. pretreating textile yarn by at least one step selecting from the group of cleaning, bleaching, mass dyeing and fast dyeing which results in conferring to said textile yarn and uniform base color over the entire cross-section thereof and having good fastness to washing and abrasion;
• 2. applying to the surface of the thus pretreated yarn a pigment composition containing a pigment dyestuff and a binder, the binder to pigment ratio not exceeding about 5:1, said pigment dyestuff being selected as to shade and amount to confer to the surface of the pretreated textile yarn a surface color having a color difference, as compared with said base color, of stage 4 or lower of the international gray scale for color change, AATCC Evaluation Procedure 1;
• 3. thermofixing the pigment composition;
• 4. subsequently subjecting the dyed textile yarn to an aqueous wash;
• and
• 5. making-up the textile yarn into a textile web after any one of step (1), step (2), step (3) and step (4).

• 3. partially thermofixing the pigment composition to produce an insufficient fixing of the pigment dyestuff and provide an abrasion fastness of the partially fixed pigment composition of at least one stage of the quoted gray scale lower than the abrasion fastness of said base color;
• and
• 4. subsequently subjecting the dyed textile web to an aqueous wash.
