Description

Technical Field

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

[0002] Ribbons and ropes woven from PP (polypropylene) yarns are widely used in various types of luggage straps, travel bags, shoelaces, mobile phone straps, etc. In order to increase the strength and tensile strength of the yarn itself, the existing PP yarn is usually a single-strand or multi-strand synthetic yarn. However, whether it is a single-strand yarn or a multi-strand yarn, the synthesized yarn is a single-core yarn, and its tensile strength and strength are still not good enough, and it is not wear-resistant enough and easy to break, resulting in the woven ribbons and ropes made of the PP yarn being easy to break, affecting product quality. Utility Model Content

[0005] As a preferred implementation, the number of the sub-wires is at least five.

[0008] As a preferred embodiment, the surface of the PP wire core is coated with a polyurethane coating.

[0009] As a preferred embodiment, the surfaces of the nylon fiber and the Kevlar fiber are coated with an anti-ultraviolet coating.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The wear-resistant and high-toughness composite PP yarn is twisted on the surface of the PP core to form at least eight toughened cores. The carbon fiber has the advantages of high tensile strength, strong corrosion resistance, strong shock resistance and strong impact resistance, and the glass fiber has high mechanical strength and good corrosion resistance, thereby enhancing the strength and toughness of the PP yarn and making the PP yarn less likely to break.

[0012] The wear-resistant and high-tenacity composite PP yarn is provided with at least five sub-threads. The nylon fiber has extremely strong wear resistance and fatigue resistance, and the Kevlar fiber has extremely high strength and wear resistance, thereby enhancing the wear resistance of the PP yarn, making the PP yarn less susceptible to wear and breakage, and improving the quality of the woven product.

[0019] See also Figure 1-3The utility model provides a wear-resistant and high-toughness composite PP yarn, including a main line 1 and a sub-line 2. The main line 1 includes a PP core 11 and a toughening core 12. There are multiple toughening cores 12, and the number of toughening cores 12 is at least eight. The multiple toughening cores 12 are spirally twisted around the PP core 11. The toughening core 12 includes carbon fiber 121 and glass fiber 122. The number of carbon fiber 121 and glass fiber 122 is the same, and the carbon fiber 121 and the glass fiber 122 are interlaced and twisted with each other. At least eight toughening cores 12 are twisted on the surface of the PP core 11. The carbon fiber 121 has the advantages of high tensile strength, strong corrosion resistance, strong shock resistance, and strong impact resistance. The glass fiber 122 has high mechanical strength and good corrosion resistance, thereby enhancing the strength and toughness of the PP yarn and making the PP yarn less likely to break.
