Patent Searching and Data


Title:
耐熱性複合布シート
Document Type and Number:
Japanese Patent JP4769807
Kind Code:
B2
Abstract:
A thermally-resistant composite fabric sheet for use as single or outer layer of protective garments, comprises inside and outside fabric layers (B,A) joined together by an array of connection lines ( 12,22,32 ) arranged so that the inside layer forms bubble-like pockets ( 16 ) when the outside layer (A) is caused to shrink by the external application of intense heat. The array of connection lines ( 12,22,32 ) is constituted by a plurality of isolated single connection lines ( 22 ) and/or by a plurality of isolated groups of connection lines ( 12,32 ), for example forming a series of Y or V shapes. The connection lines are arranged at different angles and are spaced apart from one another to leave gaps ( 42 ) where the two layers (A,B) are not connected to one another. These gaps ( 42 ) unite a continuous expanse ( 40 ) of the two unconnected layers that surrounds each isolated connection line ( 22 ) or group of connection lines ( 12,32 ). This continuous expanse ( 40 ) has a labyrinth-like structure delimited by the connection lines ( 12,22,32 ) at different angles, such that when a given area of the outside layer (A) is subjected to intense heat resulting in thermal shrinkage the inside layer (B) forms under the given area a series of self-closing bubble-like pockets ( 16 ) that form individually in discrete areas of the continuous expanse ( 40 ) between the connecting lines ( 12,22,32 ) and that are inhibited by the labyrinth-like structure from propagating along or across the sheet.
