Laminated body for vehicle and method of producing the same

Abstract

A laminated body for a vehicle includes a surface material, a cushion material, and a backing cloth that are stacked. The backing cloth is formed by stacking a plurality of short fibers so that the short fibers are oriented in different directions that cross each other, and then, three-dimensionally interlacing the short fibers with each other.

1 . A laminated body for a vehicle, comprising:
 a surface material;   a cushion material; and   a backing cloth formed by stacking a plurality of short fibers so that the short fibers are oriented in different directions that cross each other, and three-dimensionally interlacing the short fibers with each other,   wherein the surface material, the cushion material, and the backing cloth are stacked.   
   
   
       2 . The laminated body according to  claim 1 , wherein:
 the backing cloth includes a first belt-shaped web that includes the short fibers that are carded;   the first belt-shaped web is folded in a zigzag manner on a belt conveyer so that the short fibers are oriented in the different directions that cross each other and that cross a conveyance direction in which the belt conveyer conveys the first belt-shaped web; and   the short fibers of the folded first belt-shaped web are three-dimensionally interlaced with each other physically or mechanically.   
   
   
       3 . The laminated body according to  claim 2 , wherein:
 the backing cloth includes the first belt-shaped web and a second belt-shaped web that includes the short fibers that are carded;   the second belt-shaped web is folded in the zigzag manner on the folded first belt-shaped web so that the short fibers are oriented in the different directions that cross each other and that cross the conveyance direction in which the belt conveyer conveys the first belt-shaped web and the second belt-shaped web; and   the short fibers of the first belt-shaped web and the second belt-shaped web are three-dimensionally interlaced with each other physically or mechanically.   
   
   
       4 . The laminated body according to  claim 2 , wherein:
 the first belt-shaped web is folded so that four layers are formed; and   a vertex, which is formed by an edge of one layer of the four layers and an edge of an upper layer located on the one layer, is positioned at a substantially center of a length of a lower layer located immediately under the one layer, in the conveyance direction, the edge of the one layer extends in parallel with the direction in which the short fibers in the one layer are oriented, and the edge of the upper layer extends in parallel with the direction in which the short fibers in the upper layer are oriented.   
   
   
       5 . The laminated body according to  claim 1 , wherein:
 the backing cloth is made of cellulosic short fibers and synthetic fibers; and   a ratio of the synthetic fibers to all the short fibers is 20% to 50% by weight.   
   
   
       6 . A method of producing a laminated body for a vehicle, in which a surface material, a cushion material, and a backing cloth are stacked, the method comprising:
 folding a first belt-shaped web, which includes a plurality of short fibers that are carded, in a zigzag manner on a belt conveyer so that the short fibers are oriented in different directions that cross each other, and cross a conveyance direction in which the belt conveyer conveys the first belt-shaped web;   folding a second belt-shaped web, which includes a plurality of short fibers that are carded, in a zigzag manner on the belt conveyer so that the short fibers are oriented in different directions that cross each other, and cross the conveyance direction, thereby forming a laminated web in which the first belt-shaped web and the second belt-shaped web are stacked;   three-dimensionally interlacing the short fibers of the laminated web with each other physically or mechanically, thereby forming the backing cloth; and   arranging the surface material, the cushion material, and the backing cloth in a stated order, and then, joining the surface material, the cushion material, and the backing cloth, thereby forming the laminated body.   
   
   
       7 . A method of producing a laminated body for a vehicle, in which a surface material, a cushion material, and a backing cloth are stacked, the method comprising:
 folding a first belt-shaped web, which includes a plurality of short fibers that are carded, in a zigzag manner on a belt conveyer so that an even number of layers are formed, and the short fibers are oriented in different directions that cross each other, and cross a conveyance direction in which the belt conveyer conveys the first belt-shaped web;   three-dimensionally interlacing the short fibers in all the layers of the first belt-shaped web with each other physically or mechanically, thereby forming the backing cloth; and   arranging the surface material, the cushion material, and the backing cloth in a stated order, and then, joining the surface material, the cushion material, and the backing cloth, thereby forming the laminated body.   
   
   
       8 . The method of producing the laminated body for a vehicle according to  claim 7 , wherein
 the first belt-shaped web is folded so that four layers are formed.
