Wadding

Abstract

Wadding of the present invention is obtained by mixing 20% by mass or more and 95% by mass or less of an acrylic fiber and 5% by mass or more and 80% by mass or less of a polyester fiber, in which a down power is 140 cm 3 /g or more and 300 cm 3 /g or less, and a warmth retention property (Clo value) is 3.7 or more and 5 or less.

         5 . The wadding according to  claim 1 ,
 wherein the down power is 160 cm 3 /g or more and 200 cm 3 /g or less.   
     
     
         6 . The wadding according to  claim 1 ,
 wherein the Clo value is 3.8 or more and 4.8 or less.   
     
     
         7 . The wadding according to  claim 1 ,
 wherein the Clo value is 4 or more and 4.7 or less.   
     
     
         8 . The wadding according to  claim 1 ,
 wherein the single fiber fineness of the acrylic fiber is 0.5 dtex or more and 2.2 dtex or less, and   the single fiber fineness of the polyester fiber is 1.7 dtex or more and 2.2 dtex or less.   
     
     
         9 . The wadding according to  claim 1 ,
 wherein a fiber length of the acrylic fiber is 15 mm or more and 40 mm or less, and   a fiber length of the polyester fiber is 10 mm or more and 40 mm or less.   
     
     
         10 . The wadding according to  claim 1 ,
 wherein a mixing ratio of a heat-bonding short fiber with respect to the wadding is 5% by mass or more and 30% by mass or less, and   at least a part of the heat-bonding short fiber is bonded to the acrylic fiber or the polyester fiber.   
     
     
         11 . The wadding according to  claim 1 ,
 wherein 30% by mass or more and 70% by mass or less of the acrylic fiber and 30% by mass or more and 70% by mass or less of the polyester fiber are mixed, and   the wadding is granular wadding in which one or a plurality of fibers are intertwined.   
     
     
         12 . The wadding according to  claim 11 ,
 wherein the polyester fiber is a conjugate fiber and has a coil-like form in a no-load state.   
     
     
         13 . The wadding according to  claim 11 ,
 wherein the maximum length of the granular wadding is 2 mm or more and 20 mm or less.
