ABSTRACT:
TECHNICAL FIELD
The present invention relates to a seamless warp knit fabric comprising a fabric portion (also referred to as a ground structure) and a lace portion that are integrally knitted.
BACKGROUND ART
In a conventional warp knit fabric, the fabric portion and the lace portion are separately knitted, for example, by using a raschel machine. Therefore, they are integrated exclusively by sewing, for example, when attaching the lace portion to the peripheral portion of the fabric portion of women's underwear (shorts, slips and the like), negligees, and the like.
In sewing, however, the sewn portion is necessarily thicker than the fabric portion and the lace portion. Therefore, such a warp knit fabric is not comfortable for wearing. Furthermore, the seam line protrudes outside, so that there are problems in fashion and design as well. In addition, in a conventional warp knitting machine, the knitting speeds of the fabric portion and the lace portion are different from each other because the densities of stitches of the fabric portion and the lace portion are different from each other. Therefore, the fabric portion and the lace portion cannot be knitted uniformly when trying to knit the fabric portion and the lace portion integrally.
DISCLOSURE OF INVENTION
In order to solve the above problems, it is an object of the present invention to provide a seamless warp knit fabric comprising a fabric portion and a lace portion that are integrally knitted so as to form one continuous warp knit fabric.
In order to achieve the purpose, a seamless warp knit fabric of the present invention comprises a continuous warp knit fabric comprising a fabric portion and a lace portion that are integrally knitted in the advance direction of stitches.
It is preferable that the width of the fabric portion is at least three times the width of the lace portion, because such a seamless warp knit fabric is suitable for using the fabric portion widely inside and locating the lace portion in an outside narrow portion when it is used for inner wear such as underwear.
It is preferable that a plurality of the lace portions are formed in the advance direction of stitches, because such a seamless warp knit fabric is suitable to use with left-right symmetric location when it is used for inner wear such as underwear.
It is preferable that the warp knit fabric is at least one knit fabric selected from the group consisting of a knit fabric using inelastic yarns (a rigid knit fabric), a knit fabric using elastic yarns in one direction (a one-direction stretchable knit fabric), and a knit fabric using elastic yarns in two directions (a two-direction stretchable knit fabric). The rigid knit fabric is useful for a blouse, a tablecloth, or the like. The one-direction or two-direction stretchable knit fabric is useful for inner wear such as underwear. Any one of the knit fabrics can be used for a negligee.
It is preferable that the yarn of the fabric portion is a covered yarn in which an elastic filament yarn is wound around an inelastic filament yarn, because such a seamless warp knit fabric is excellent in elasticity and touch. Any yarn can be used as the inelastic fiber yarn, for example, a synthetic filament yarn such as a nylon filament yarn or a polyester filament yarn, a spun yarn of synthetic staples such as nylon staples, polyester staples, or acrylic staples, a chemical fiber yarn such as a rayon yarn, a natural fiber yarn such as a cotton yarn, a linen yarn, a silk yarn, or a wool yarn, or a blended spun yarn such as polyester/cotton or rayon/cotton.
In addition, the fabric portion (the ground structure) may be a knit fabric selected from the group consisting of a solid-colored knit fabric and a knit fabric having a solid-colored pattern.
Furthermore, the fabric portion (the ground structure) may be a knit fabric selected from the group consisting of a single knitted structure and a double knitted structure. When the fabric portion (the ground structure) is a double knitted structure and such a seamless warp knit fabric is sewn for lingerie (underwear) such as shorts, slips, and the like, or negligees, the impression of being see-through is not provided. Therefore, a high-grade knit fabric can be provided. On the contrary, when the fabric portion (the ground structure) is a single knitted structure, the impression of being see-through can be provided.
It is preferable that the lace portion is a knit fabric selected from the group consisting of a knit fabric forming a pattern and a knit fabric forming a narrow lace portion.
Furthermore, an end of the seamless warp knit fabric can be formed by drawing a yarn from the knitted structure in at least one boundary between the lace portion and the fabric portion adjacent to the lace portion. Of course, the seamless warp knit fabric can be cut with scissors or a cutting machine. In addition, the end of the knit fabric may be linear or curved.
As described above, according to the present invention, the fabric portion and the lace portion are integrally knitted in the advance direction of stitches, so that the sewn portion between the fabric portion and the lace portion can be eliminated. Therefore, a warp knit fabric that is comfortable for wearing and is excellent in fashion and design without the protrusion of the seam line can be provided.
