Tufted carpet

Abstract

A tufted carpet has a high density portion and a low density portion. The high density portion has pile yarns implanted into a base fabric with high density. The low density portion has pile yarns implanted into the base fabric with low density. The fiber density of the high density portion is in the range of 280 to 700 g/m 2 . The fiber density of the low density portion is in the range of 200 to 500 g/m 2 . The fiber density of the high density portion is set to a value greater than the fiber density of the low density portion. The difference between the fiber density of the high density portion and the fiber density of the low density portion is set to a value in the range of 30 to 250 g/m 2 .

1 . A tufted carpet comprising: pile yarns implanted into a base fabric;
 a high density portion having the pile yarns implanted into the base fabric with a high density; and   a low density portion having the pile yarns implanted into the base fabric with a low density.   
     
     
         2 . The tufted carpet according to  claim 1 , wherein:
 the fabric density of the high density portion is in the range of 280 to 700 g/m 2 ;   the fabric density of the low density portion is in the range of 200 to 500 g/m 2 ; and   the fabric density of the high density portion is set to a value greater than the fabric density of the low density portion.   
     
     
         3 . The tufted carpet according to  claim 1 , wherein:
 the stitch of the high density portion is in the range of 8.0 to 17.0;   the stitch of the low density portion is in the range of 6.0 to 12.0; and   the stitch of the high density portion is set to a value greater than the stitch of the low density portion.   
     
     
         4 . The tufted carpet according to  claim 1 , wherein the difference between the fiber density of the high density portion and the fiber density of the low density portion is in the range of 30 to 250 g/m 2 . 
     
     
         5 . The tufted carpet according to  claim 1 , wherein the high density portion of the tufted carpet is formed by making the speed for moving the base fabric in a tufting machine lower than the speed for moving the base fabric at the time when the low density portion is being formed.
