[0001] The utility model relates to the technical field of textile yarns, in particular to a composite yarn. Background Art
[0002] There are endless yarns on the market with different materials and structures, which are widely used in weaving, rope making, thread making and other areas of life.
[0003] Slub yarn is the most common type of fancy yarn. Its notable feature is that the yarn is sometimes thin and sometimes thick. The overlapping parts of the yarn are called slub yarns, and the slub yarns can be regularly or irregularly distributed. During processing, it is generally divided into air-spun slub yarn and ring-spun slub yarn.
[0004] At present, the existing slub yarn has a good three-dimensional sense due to its sometimes thin and sometimes thick appearance. However, since the slub yarn has protruding slub nodes, when it is made into fabric and used, the slub nodes will frequently come into contact and friction with the outside world, which can easily cause wear and tear and poor durability.

[0007] As a further configuration of the utility model, the wire core comprises a shaped polyester fiber monofilament, the cross section of the shaped polyester fiber monofilament is cross-shaped, and a plurality of elastic yarns are arranged between the shaped polyester fiber monofilament and the reinforcing yarn.
[0008] As a further configuration of the utility model, the elastic yarn is formed by spirally twisting a first winding and a second winding, the first winding is formed by twisting a plurality of spandex fibers, and the second winding is formed by twisting a plurality of bamboo charcoal fibers.
[0009] As a further configuration of the utility model, the yarn body is formed by twisting two base yarns, and the base yarn includes an inner core and a covering yarn spirally wound around the outer side of the inner core.
[0010] As a further configuration of the utility model, the inner core is formed by twisting a plurality of hemp fibers.
[0011] As a further configuration of the utility model, the covered yarn is formed by twisting a plurality of lyocell fibers.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model wraps the bamboo joints with wear-resistant yarns. When the yarns are made into fabrics and used, the wear-resistant yarns block the bamboo joints from directly contacting and rubbing with the outside world, thereby avoiding wear and tear, and greatly improving the durability of the composite yarn.
