Disclosed is a fibrous web which includes a microencapsulated material,
such as a microencapsulated phase change material, adhered to the web.
Preferably, the web is prepared in a melt-blowing or spun-bonding
process. In the melt-blowing process, cooling water containing the
microcapsules is used to cool melt blown fibers prior to collection on a
collector. In the spun-bonding process, microcapsules are applied in
liquid suspension or in dry form to a heated web, for instance, after the
web has been calendared. The fibrous webs thus prepared have numerous
uses, and are particularly suited to the manufacture of clothing.
