Abstract
Nonwoven fabrics may be fashioned as topical delivery systems with increased and controllable rate of product release, while still possessing the requisite strength and durability for mass production and distribution. Such delivery systems comprise fabrics that are fashioned from micro-denier fibers that are produced by fibrillating bicomponent island-in-the-sea fibers. Facial masks made from these fabrics can achieve adequate product delivery in 3-5 minutes or less.
Claims7
A sheet mask for delivering a liquid composition to a skin surface, the sheet mask comprising an island-in-the sea nonwoven fabric made from bicomponent island-in-the-sea fibers, wherein:
- the bicomponent island-in-the sea fibers comprise:
- an island fiber made from a first polymeric material;
- a sea fiber made from a second polymeric material;
- the weight ratio of the first polymeric material to the second polymeric material is between 1:4 and 1:6;
- the fiber packing density of the nonwoven fabric is 5%-30%;
- and
- the sea and island fibers are entangled by water-jetting with a jet-to-jet spacing of 600μ-2400μ.
