Abstract
Down-proof baffles are described herein. An example down-proof baffle may comprise composite material. The composite material may be or comprise the shell of the example down-proof baffle. The example composite material may comprise a membrane disposed adjacent one or more layers.
Claims14
A down-proof baffle having a baffle shell formed from a composite material, wherein the composite material comprises:
- a membrane;
- a face layer disposed adjacent a first side of the membrane;
- and
- a backer layer disposed adjacent a second side of the membrane opposite the face layer to effect the downproofing;
- wherein the composite material exhibits a low range hydrostatic water resistance as received of between 5000 mm and 15000 mm and, after 20 launderings, of between 2000 mm and 6000 mm, each as measured using AATCC 127,
- wherein the composite material exhibits an air permeability of between 0.40 cfm and 0.90 cfm as measured using ASTM D737, and
- wherein the composite material exhibits a moisture vapor transmission rate (MVTR) of greater than 8000 g/sqm/24 hr as measured using JIS L1099-B1,
- wherein the composite material exhibits a high range hydrostatic water resistance, after 20 launderings, of between 23 psi and 39 psi as measured using ASTM D751, and
- wherein the composite material has a fabric weight of less than 200 gsm.
