Knitted fabric and knitted fabric joining method

Abstract

Provided is a knitted fabric in which a first knitted fabric portion and a second knitted fabric portion that overlap each other in the thickness direction are joined to each other so as to be easily rotated about a joint position of the two knitted fabric portions, which serves as a rotation axis. The knitted fabric includes: a passage location (7) at which stitches ( 4 a to 4 d ) of the n-th knitting course ( 4 A) of the second knitted fabric portion ( 4 ) are passed through gaps between stitches in the first knitted fabric portion ( 2 ) from one surface side to the other surface side, so that the up and down positions in the thickness direction of the first knitted fabric portion ( 2 ) and the second knitted fabric portion ( 4 ) are reversed with respect to each other. Furthermore, a terminal portion ( 4 y ) of the second knitted fabric portion ( 4 ) is subjected to an unravel treatment in the vicinity of the passage location at which the second knitted fabric portion ( 4 ) is passed through the first knitted fabric portion ( 2 ), so that the first knitted fabric portion ( 2 ) and the second knitted fabric portion ( 4 ) are joined to each other at the passage location ( 7 ) . Here, the gaps are each surrounded by two adjacent stitches ( 2 a and 2 b through 2 d and 2 e ) in the m-th knitting course ( 2 A) of the first knitted fabric portion ( 2 ), a sinker loop that connects the adjacent stitches, and a sinker loop in the (m+ 1 )-th knitting course ( 2 B).

1 . A knitted fabric in which a first knitted fabric portion and a second knitted fabric portion that overlap each other in a thickness direction in a two-layer independent state are joined to each other, comprising:
 when n and m are suitable natural numbers,   a passage location at which stitches in an n-th knitting course of the second knitted fabric portion are passed through gaps between stitches in the first knitted fabric portion from one surface side to another surface side, so that up and down positions in the thickness direction of the first knitted fabric portion and the second knitted fabric portion are reversed with respect to each other,   wherein a terminal portion of the second knitted fabric portion is subjected to an unravel treatment in the vicinity of the passage location, so that the first knitted fabric portion and the second knitted fabric portion are joined to each other at the passage location, and   the gaps are each surrounded by two adjacent stitches in an m-th knitting course of the first knitted fabric portion, a sinker loop that connects the adjacent stitches, and a sinker loop in an (m+1)-th knitting course.   
     
     
         2 . The knitted fabric according to  claim 1 ,
 wherein the stitches in the n-th knitting course are respectively passed through the plurality of gaps lined up in a predetermined range of the m-th knitting course.   
     
     
         3 . The knitted fabric according to  claim 1 ,
 wherein the first knitted fabric portion is a shoe upper, and the second knitted fabric portion is a tongue, and   a start portion of the shoe upper is formed in the vicinity of the passage location.   
     
     
         4 . A knitted fabric joining method for joining a first knitted fabric portion and a second knitted fabric portion that overlap each other in a thickness direction in a two-layer independent state, using a flat knitting machine with two needle beds, comprising:
 when n and m are suitable natural numbers,   a step of holding an m-th knitting course of the first knitted fabric portion on one needle bed, and holding an n-th knitting course of the second knitted fabric portion on the other needle bed;   a step of moving stitches in the m-th knitting course to the other needle bed and moving stitches in the n-th knitting course to the one needle bed, so that the front and back positions of the first knitted fabric portion and the second knitted fabric portion are reversed with respect to each other in a state in which the stitches in the n-th knitting course are passed through spaces between the stitches in the m-th knitting course;   a step of subjecting the n-th knitting course to an unravel treatment, or knitting several knitting courses that follow the n-th knitting course in a wale direction and then performing an unravel treatment; and   a step of knitting several knitting courses that follow the m-th knitting course.   
     
     
         5 . The knitted fabric according to  claim 2 ,
 wherein the first knitted fabric portion is a shoe upper, and the second knitted fabric portion is a tongue, and   a start portion of the shoe upper is formed in the vicinity of the passage location.
