ABSTRACT:
The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and porosity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents. Alternatively, it has also been discovered that an anionic derivative can be used to catalyze permanent press resins onto fabrics containing cellulosic fibers, also resulting in anionic cotton.
