Description

Technical Field

[0001] The utility model belongs to the technical field of yarns, and in particular relates to a high-strength composite yarn. Background Art

[0002] Yarn is a textile product that is made of various textile fibers and processed into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. Traditional yarns such as polyester yarns have high strength and their wear resistance can be further improved after twisting. However, the tensile strength of polyester yarns is relatively low. After twisting, its tensile strength will be further reduced, resulting in an increased risk of breakage during use.

[0003] To this end, the applicant has conducted useful explorations and attempts and found solutions to the above problems. The technical solutions to be introduced below were produced in this context. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a high-strength composite yarn.

[0005] The above technical problems of the utility model are mainly solved by the following technical scheme: a high-strength composite yarn, including a core layer, a reinforcement layer and an outer covering layer, wherein the reinforcement layer wraps the outer periphery of the outer core layer, and the outer covering layer wraps and is wound around the outer periphery of the reinforcement layer, and the core layer includes 3 base wires and structural wires, and the structural wires are staggered and wound on the 3 base wires in a spiral form.

[0006] Preferably, the reinforcement layer includes a plurality of reinforcement wires and the plurality of reinforcement wires are spirally wound around the periphery of the core layer.

[0007] Preferably, the outer covering layer comprises a plurality of wear-resistant wires 1 and 2, and the plurality of wear-resistant wires 1 are all spirally wound around the periphery of the reinforcement layer, and a wear-resistant wire 2 is arranged between every two adjacent wear-resistant wires 1.

[0008] Preferably, the diameter of the wear-resistant wire one is greater than the diameter of the wear-resistant wire two.

[0009] Preferably, the twist of the wear-resistant wire 1 and the wear-resistant wire 2 are both 1200-1500 twists / m.

[0010] The utility model has the beneficial effects:

[0011] Compared with the prior art, the utility model arranges a structural wire to wrap and bundle multiple base wires into a whole, thereby enhancing the tensile strength of the yarn. By arranging a reinforcement layer and an outer covering layer, the structural strength and wear resistance of the yarn itself can be improved, thereby ensuring the structural integrity of the yarn and preventing the yarn from becoming loose.
