Abstract: A process for producing an ionic crosslinked fibrous material, such as a cellulosic fabric, paper, or other substrate, wherein the ionic crosslinked fiber exhibits an increased wrinkle resistance angle. A process for producing a cationized chitosan, wherein the cationized chitosan exhibits cationization at the C6 and ring hydroxyl sites and the reactivity of the ring NH2 sites is preserved. A process for applying a polycation to an anionic fibrous material to form an ionic crosslinked fibrous material. A process for producing a cationized fibrous material, wherein the process is performed as a pad-batch process, an exhaust fixation process, a pad-steam process, or a pad-dry-cure process.

Abstract: Water-soluble, i.e. easily dispersible, amino-functional polyorganosiloxanes obtained by radical polymerization of vinyl compounds containing amino or ammonium groups onto polyorganosiloxanes which contain at least one mercapto group. They are suitable as textile finishing aids, surfactants and emulsifiers.
