Knitted fabric for promoting heat dissipation

Abstract

A knitted fabric for promoting heat dissipation is to be an insole and covers a wearer's skin when in use, and has two surface layers, an intermediate layer, and multiple channels. The two surface layers are disposed at a spaced interval, and include a first surface layer and a second surface layer oriented to the wearer's skin when the knitted fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight and extends in a widthwise direction. The intermediate layer is formed with multiple monofilaments knitted between the two surface layers and divergently stretch out from each braid toward the first surface layer. Each monofilament intercrosses with another at a point near the first surface layer. A channel is formed among the intermediate layer and adjacent two said braids and has a V-shaped cross section.

What is claimed is: 
     
         1 . A knitted fabric for promoting heat dissipation, the knitted fabric configured to be an insole which has a widthwise direction and covering a wearer's skin when in use, and comprising:
 two surface layers disposed at a spaced interval, and comprising
 a first surface layer having
 multiple first fibers disposed parallelly; and 
 multiple second fibers, each one of the multiple second fibers shuttled back and forth and knitted with the multiple first fibers; and 
 
 a second surface layer oriented to the wearer's skin when the knitted fabric is in use, and having
 multiple braids disposed parallelly, each one of the multiple braids being straight and extending in the widthwise direction of the insole; 
 
   an intermediate layer formed with multiple monofilaments which are knitted between the multiple braids of the second surface layer and the first surface layer and divergently stretch out from each one of the multiple braids toward the first surface layer, and each one of the monofilaments intercrosses with another monofilament at a point near the first surface layer and away from the second surface layer; and   multiple channels, each one of the multiple channels formed among the intermediate layer and adjacent two of the multiple braids and having a V-shaped cross section.   
     
     
         2 . The knitted fabric as claimed in  claim 1 , wherein each one of the multiple braids is made of a first yarn and a second yarn interlaced with the first yarn.
