Embodiment Construction

[0016] Such as Figure 1-2 As shown, a polyester and polypropylene composite cable comprises twelve strands 1 braided together, of which six strands are left twisted strands and six strands are right twisted strands; said strands 1 include twisted strands formed Outer layer 2, middle layer 3, inner layer 4, core layer 5 polyester and polypropylene fiber twisted yarn.

[0017] A kind of polyester and polypropylene composite cable preparation process of the present invention comprises the following steps:

[0018] 1) Select raw materials: The selected raw materials are polyester and polypropylene fibers, the fiber strength is 2.5-3.5Gpa, the breaking strength is greater than 30cn / dtex, and the fiber surface is required to be smooth and clean;

[0019] 2) Twisting: When twisting, the tension of the twisting machine drive belt should be consistent. Each yarn must be controlled by a tensioner, and the rotation speed and twist should be tested regularly. The twist of each layer of ...

Abstract

The invention relates to a polyester and polypropylene compound mooring rope and a preparation process thereof. The polyester and polypropylene compound mooring rope comprises twelve strands which are knitted into a whole, wherein six strands are used as left twisted strands and other six twisted strands are used as right twisted strands; the strands comprise outer layers, intermediate layers, inner layers and core layers which are formed by twisting and other polyester and polypropylene fiber twisting wires; the preparation process comprises the following steps: (1) selecting raw materials; (2) twisting wires; (3) producing strands; and (4) forming ropes. The invention has the beneficial effects that the mooring rope not only has the characteristics of low density, light weight, high strength, favorable specific modulus and impact resistance and the like which are the same as the characteristics of like products, but also has the performances of corrosion resistance, fatigue resistance, wear resistance, heat resistance, high melting point, ultraviolet ray resistance and the like; the wear resistance is about 8 percent higher than that of the like products, the fracture strength is 10 percent higher than that of the like products, the compressive strength is high and the structure is reasonable, attractive and practical.

Description

technical field [0001] The invention relates to a polyester and polypropylene composite cable and a preparation process thereof. Background technique [0002] At present, the annual demand for marine cables in China is close to 10,000 tons. With the improvement of my country's economic development level, marine cables made of high-performance fibers will gradually replace existing ship cables. Polyester and polypropylene composite cables are widely used in marine projects such as oil tankers and asphalt ships due to their light weight, high strength, long service life, wear resistance, moisture resistance, and large elongation at break, and their development speed is extremely rapid; however, polyethylene fibers exist The following defects: 1), due to the low interface bonding strength, due to the inertness and non-polarity of the polyethylene fiber surface, the wettability is poor, so the interface bonding strength between the fiber and the matrix is ​​low, which affects th...
