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.
A textile composite article comprising textile fibers impregnated by a continuous polymers network creating a pattern of impregnated areas in the textile in which said polymers network penetrates fully within the textile and comprises natural polymer (NP) crosslinked to synthetic polymer (SP) in the absence of non-polymeric crosslinking agent and said textile composite article having a water absorbency by at least 10% higher in comparison to same textile without said polymers network.
