<p>A composite, suitable for application to the waist of a disposable nappy comprises a web of non-woven textile material impregnated with a stiffening agent e.g. sucrose. Elastic strands in a stretched condition are adhesively secured to the web, but the stiffness of the web is sufficient to resist the contractile forces of the elastic material. The composite is activated by treatment with a suitable agent, e.g. saturated steam, in order to reduce the stiffness of the web.</p> |
