Abstract: The present invention relates to a process for production of water-absorbing textile composite materials comprising the use of a polymeric composite solution and a textile material (non-woven, woven and other). The textile material is impregnated with the composite polymeric solution, which after thermal treatment is cross-linked in situ. More particularly, the present invention relates to an absorbent textile composite article comprising textile fibers and a polymers network interpenetrating the textile fibers, the polymers network comprising natural polymer crosslinked to synthetic polymer in the absence of non-polymeric crosslinking agent. The textile composite article exhibits excellent absorbency of aqueous media such as food liquids, cosmetic liquids, pharmaceutical liquids or human body secretions.
