<p>Disclosed is a process for preparing a fibrous web. The fibrous web 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 (12) process, cooling water (17) containing the microcapsules is used to cool melt blown fibers prior to collection on a collector (16). In the spun-bonding (21) process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendered (28, 29). The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.</p> |
