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 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 fibr...
1. A process for preparing a fibrous web, comprising:providing a polymeric melt comprising a thermoplastic polymer; melt-blowing a body of fibers from said solution, said body comprising a plurality of fibers, said fibers being at a temperature sufficient to render said fibers tacky; cooling said body with a cooling medium, said cooling medium including a cooling liquid and discrete plural particles of an adherent, whereby at least some of said discrete particles adhere to said body; and collecting said body on a collector thereby forming a web. 2. A pro...
