DOWN PROOF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a down proof structure having air permeability excellent in blowing in and filling feathers and shape recovery in using, preventing blowing-out of feathers, and excellent in durability allowing to retain feather blowing-out preventing effect even in the case of long time use and high use frequency. SOLUTION: This down proof structure includes feathers in an outer fabric formed in a bag-like shape. A cotton pad nonwoven fabric which lies between the outer fabric and the feathers is made of a nonwoven fabric which has an average fineness of the constituent fiber of 0.5-5 decitex, a thickness of 5-20 mm, and a surface density of 50-200g/m2. The ventilation volume of the outer fabric is 3-15 (cm3/cm2×s). COPYRIGHT: (C)2009,JPO&INPIT
