There is disclosed a non-woven material having a superficial coating of a linear polymeric biguanide in which the recurring unit is of the formula ##STR1## wherein X and Y, which may be the same or different, represent bridging groups in which the total number of carbon atoms in X and Y taken together, directly interposed between the pairs of nitrogen atoms linked thereby, is from 10 to 16, or the salt thereof with an acid. Preferably the polymeric biguanide is polyhexamethylene biguanide dihydrochloride. The material is useful in the form of an article designed for the collection of human body emissions, more particularly disposable nappies to avoid bacterial activity.
