Circular knitted fabric

Abstract

Provided is a circular knitted fabric that has a good balance in elongation between a wale direction and a course direction, and also a knitted pattern. A circular knitted fabric having a 1×1 rib jacquard knitted structure as a basic structure, in which non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted, knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is included so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location, elongation in each of a wale direction and a course direction is 100 to 280% under a load condition of 14.7 N/2.54 cm, and an elongation ratio, that is, (elongation in wale direction)/(elongation in course direction), is 0.5 to 2.0 under the load condition of 14.7 N/2.54 cm.

1 . A circular knitted fabric having a 1×1 rib jacquard knitted structure as a basic structure,
 wherein non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted, 
 knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is included so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location, 
 elongation in each of a wale direction and a course direction is 100 to 280% under a load condition of 14.7 N/2.54 cm, and 
 an elongation ratio, that is, (elongation in wale direction)/(elongation in course direction), is 0.5 to 2.0 under the load condition of 14.7 N/2.54 cm. 
 
     
     
         2 . The circular knitted fabric according to  claim 1 , wherein a finished knitting density is 105 courses or more/2.54 cm and 48 wales or more/2.54 cm. 
     
     
         3 . The circular knitted fabric according to  claim 1 , wherein fineness of the elastic fiber yarn is 11 to 110 dtex, and fineness of the non-elastic fiber yarn is 11 to 110 dtex, and
 the fineness of the elastic fiber yarn:the fineness of the non-elastic fiber yarn is 1:0.3 to 1:4.5.   
     
     
         4 . The circular knitted fabric according to  claim 1 , wherein as for the non-elastic fiber yarn at least two types of non-elastic yarns are used. 
     
     
         5 . The circular knitted fabric according to  claim 4 , wherein as for the non-elastic fiber yarn, the two types of non-elastic yarns which are different in fineness are used, and a fineness ratio is 1:0.5 to 1:4. 
     
     
         6 . A method of manufacturing a circular knitted fabric in which a 1×1 rib jacquard knitted structure is knitted as a basic structure, wherein non-elastic fiber yarn and elastic fiber yarn are fed as a full set and plate-knitted:
 knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is formed so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location; and 
 in feeding each of the non-elastic fiber yarn and the elastic fiber yarn, while tension of yarn to be supplied is monitored, an amount of fed yarns is adjusted such that the tension is kept constant. 
 
     
     
         7 . The circular knitted fabric according to  claim 2 , wherein fineness of the elastic fiber yarn is 11 to 110 dtex, and fineness of the non-elastic fiber yarn is 11 to 110 dtex, and
 the fineness of the elastic fiber yarn:the fineness of the non-elastic fiber yarn is 1:0.3 to 1:4.5.   
     
     
         8 . The circular knitted fabric according to  claim 2 , wherein as for the non-elastic fiber yarn, at least two types of non-elastic yarns are used. 
     
     
         9 . The circular knitted fabric according to  claim 3 , wherein as for the non-elastic fiber yarn, at least two types of non-elastic yarns are used.
