Description

Following is a sample of the information contained on this CD: TECHNICAL FIELD This invention relates to a composite yarn comprised of a chain stitch yarn and at least one inlay yarn and a manufacturing method thereof. More particularly, this invention relates to a composite yarn having a novel structure which can be obtained by using a warp knitting machine and remarkable features which cannot be obtained in conventional composite yarns, but can be obtained by the above-mentioned novel structure, and a manufacturing method thereof. PRIOR ART Various types of composite yarn have been known. In general, composite yarn is divided into two types, and one type of composite yarn is a yarn composed of fibers constituted with at least two components and another type of composite yarn is a yarn in which at least two yarns constituting the composite yarn are combined with each other. The composite yarn of the present invention is of the latter type. A typical yarn of the latter composite yarn type is a twisted yarn. The twisted yarn has superior tensile strength and abrasion resistance, compared with a single yarn, and a beautiful appearance. Accordingly, the twisted yarn can be widely used in a woven fabric, a knitted fabric, a rope or the like. However, the twisted yarn is generally a non-stretchable yarn. For the sake of the above feature, when a final product having elastically stretchable property (hereinafter, referred as stretchability) is required, a cover yarn manufactured by using a stretchable yarn such as a spandex yarn as a core yarn and wrapping it with a non-stretchable yarn such as a spun yarn, a textured yarn or the like, in one layer or two layers, is used. However, since the other yarn is wrapped about the core yarn in the covering yarn, the appearance of the covering yarn becomes to dull. Accordingly, the covering yarn cannot be used in the applications of a knitted fabric or a won en fabric in which luster is required. However,
