Abstract

The invention relates to the application of high-strength high-mode polyethylene fiber to flexible optical cable manufacturing. The manufacturing method comprises the following steps of: (1) releasing an optical fiber and a high-strength high-mode polyethylene fiber, namely, releasing the optical fiber from an optical fiber disk by an optical fiber wire-releasing device, and simultaneously releasing the high-strength high-mode polyethylene fiber from a high-strength high-mode polyethylene fiber cone by a high-strength high-mode polyethylene fiber wire-releasing device and coating the high-strength high-mode polyethylene fiber on the outer part of the optical fiber; (2) extruding sheath materials by a plastic extruding machine, and coating the sheath materials on the outer part of the high-strength high-mode polyethylene fiber to obtain the semi-finished product of the flexible optical cable; and (3) cooling, blow-drying and winding the semi-finished product of the flexible optical cable to obtain the flexible optical cable. Compared with the prior art, the application of the high-strength high-mode polyethylene fiber to the flexible optical cable manufacturing improves the strength and modulus of the flexible optical cable, reduces mass of the flexible optical cable, makes the flexible optical cable possess excellent ultra-violet resistance, anti-corrosion, wear resistance and deflection, and greatly lowers the manufacturing cost of the flexible optical cable, and greatly facilitates the use of the flexible optical cable.

Description

technical field [0001] The invention relates to high-strength and high-modulus polyethylene fibers, in particular to the application of high-strength and high-modulus polyethylene fibers in manufacturing soft optical cables. Background technique [0002] With the continuous development of the communication industry, the application fields of flexible optical cables are becoming wider and wider, and the demand is also increasing. Therefore, the performance and quality requirements of flexible optical cables are also increasing. At present, most of the existing flexible optical cables use aramid fiber as the reinforcing core. This type of flexible optical cable has strong mechanical strength and can withstand large tensile and impact forces. However, the price of aramid fiber is relatively expensive, and its density, strength , modulus and elongation and other properties also have certain deficiencies, which have caused obstacles to the popularization and use of flexible optic...
