Abstract

Provided is a weft knit fabric with excellent raw edge properties and flexural softness. This weft knit fabric, which contains non-elastic yarns and elastic yarns and has a front surface and a back surface, is characterized in that: the elastic yarns connect the front surface with the back surface; the front surface and the back surface have portions wherein the non-elastic yarns and the elastic yarns form needle loops together; and the ratio of the number of sinker loops formed by the non-elastic yarns and the elastic yarns together with respect to the total number of sinker loops of the non-elastic yarns on the front surface and the back surface is not more than 50%.

First claim

The invention claimed is:

1. A weft knit fabric comprising non-elastic yarn and elastic yarn and having a front side and a back side, wherein the elastic yarn connects the front side and back side, with the front side and the back side having sections that form needle loops by doubling of the non-elastic yarn and the elastic yarn, and the proportion of the number of sinker loops formed by doubling of the non-elastic yarn and elastic yarn is 50% or lower with respect to the total number of sinker loops of the non-elastic yarn on the front side and the back side, and when the weft knit fabric is elongated with a load of 9.8 N from both a warp and a weft, the ratio between the needle loop lengths and the sinker loop lengths of the non-elastic yarn loops is 0.20 to 0.80.

2. The weft knit fabric according to claim 1 , which has no sections where the non-elastic yarn and elastic yarn form sinker loops by doubling.

3. The weft knit fabric according to claim 1 , wherein the proportion of the number of needle loops formed by doubling between the non-elastic yarn and the elastic yarn is 50% or greater with respect to the total number of needle loops of non-elastic yarn on the front side and the back side.

4. The weft knit fabric according to claim 1 , wherein the non-elastic yarn composing either the front side or the back side does not connect with the other side.

5. The weft knit fabric according to claim 1 , wherein the non-elastic yarn forms only a knit structure on the front side and the back side.

6. The weft knit fabric according to claim 1 , which has a structure in which the elastic yarn alternately repeats a knit structure on either the front side or the back side and a tuck structure on the other side, in the weft direction of the knitted fabric.

7. The weft knit fabric according to claim 1 , wherein the elastic yarn is coalesced or fused together.

8. The weft knit fabric according to claim 1 , wherein the elastic yarn and the non-elastic yarn are coalesced or fused together.

9. The weft knit fabric according to claim 1 , wherein elastic yarn is included in all of the courses of the weft knit fabric.

10. The weft knit fabric according to claim 1 , wherein the proportion of the number of courses where the non-elastic yarn and elastic yarn are knitted by plating is 50% or lower with respect to the total number of courses.
