摘要

Many hygiene and medical products require both improved methods of encapsulating actives within their structure up to the point of use and controlled release of active ingredients from within the fabric to the outer surfaces during use. Depending on the application, the release of encapsulated actives may be facilitated by wetting (e.g. by water, sweat, body fluid and blood). In this type of delivery system, the liquid permeates in to the fabric and solubilises the encapsulated material to facilitate its delivery to one or more of the outer fabric surfaces. Currently, there are various approaches to the design of nonwoven delivery systems each with particular modes of manufacture and physical properties. The paper is primarily concerned with the engineering design and function of an alternative type of nonwoven delivery system based on a family of hydroentangled spacer fabrics (known as Hydrospace~(TM) materials). These fabrics have complex microstructural architectures the features of which are strongly influenced by fibre properties and water jet conditions during manufacture and are characterised by discrete internal cavities of varying dimensions and geometrical shapes. The principle mechanisms of storage and release in such fabrics are introduced in terms of fabric microstructure and the physics of fluid flow. The structural features and dimensions of these fabrics are discussed in relation to their corresponding physical properties.
