Description

This invention is knitted stretch of weft method for manufacturing of the inserted elastic weft insertion through knitted fabric Keiami.

  Since knitted fabrics are highly stretchable and excellent in comfort when worn, clothes using knitted fabrics are widely provided in various fields. Further, in recent years, an example in which a knitted fabric having high comfort is used for clothes that have been manufactured using woven fabrics. However, the knitted fabric is not suitable for clothes and members that need to keep its shape because it does not have a tightness or firmness compared to the fabric of the woven fabric.

  Therefore, a fabric having characteristics of both woven fabric and knitted fabric is demanded. For example, as disclosed in Patent Document 1, a fabric in which wefts are inserted into a warp knitted fabric has been proposed. This fabric is formed by inserting wefts extending long in the course direction between the stitches of the warp knitted fabric. The wefts inserted into the fabric do not form stitches and extend straight in the course direction, and are obtained by inserting the wefts into the warp knitted fabric.
