Embodiment 1

[0020] The 600D / 192F polyester DTY low elastic yarn is twisted 5 times to obtain fiber bundles, and the fiber bundles are pulled out from the spool at a speed of 1m / min and guided to the braiding point by the guide wheel of the 24-spindle high-speed braiding machine, and braided into an inner diameter A hollow braided rope with a diameter of 2.2mm and an outer diameter of 3.2mm, and then a stainless steel wire with a length of 30cm and a diameter of 2mm is threaded in the hollow of the braided rope, and the braided rope is treated with a drum-type microwave continuous heater, and the microwave output power is controlled. 200w, the heating temperature is 200°C, and the treated braided rope is led out with a guide wheel to obtain a hollow braided rope.

Embodiment 2

[0022] Select 300D / 144F polypropylene elastic yarn and twist it 3 times to obtain fiber bundles, pull the fiber bundles from the spool at a speed of 10m / min and guide the weaving point through the guide wheel of the 32-spindle high-speed braiding machine, and weave the inner diameter of 1.6mm , a hollow braided rope with an outer diameter of 2.6mm, and then a stainless steel wire with a length of 20cm and a diameter of 1.5mm is threaded in the hollow of the braided rope, and the braided rope is treated with a drum-type microwave continuous heater, and the microwave output power is controlled to 400w. The heating temperature is 300°C, and the treated braided rope is drawn out with a guide wheel to obtain a hollow braided rope.

Embodiment 3

[0024] Select 600D / 192F polyester DTY low elastic yarn and 300D / 144F polypropylene elastic yarn as raw materials, twist the two raw materials and pull the fiber bundle from the bobbin at a speed of 4m / min through the guide wheel of the 42-spindle high-speed braiding machine Lead to the braiding point, weave into a hollow braided rope with an inner diameter of 1.0mm and an outer diameter of 2mm, and then pass a stainless steel wire with a length of 5cm and a diameter of 0.9mm in the hollow of the braided rope, and treat it with a drum type microwave continuous heater For the braided rope, the microwave output power is controlled to be 450w, and the heating temperature is 350° C., and the treated braided rope is led out with a guide wheel to obtain a hollow braided rope.

Abstract

The invention relates to a manufacturing method and an application of a hollow braided rope. The manufacturing method includes the steps of selecting fibers of specific fineness as materials, braiding the fibers by a braider after the fibers are twisted into strands, or braiding the fibers by the braider with the fibers not twisted into strands, inserting a stainless steel wire into the hollow space of the braided rope, shaping by a drum type microwave continuous heater, and the like. The hollow braided rope is shaped by microwave heating which belongs to an internal shaping process, and original surface appearance of the braided rope fibers is maintained. Compared with traditional external heat setting processes, according to the hollow braided rope obtained by the manufacturing method, space between each two strands of the rope and between each two fibers are not too tight, the rope surface is not smooth, and bonding effects are not affected. The hollow braided rope obtained by the manufacturing method can be used as an internal supporting material for internally supporting hollow fiber membranes. The outer surface of the hollow braided rope is rough, thereby bonding performance between the rope and skin membrane materials is improved, and the skin membrane materials are prevented from falling off during usage.

Description

field of invention [0001] The invention relates to a preparation method of a hollow braided rope and its application, in particular to a preparation method of an inner support material used for inner support of a hollow fiber membrane. Background technique [0002] Rope is a special variety of the textile industry, widely used in civil, national defense and other fields, such as for ships, lifting and unloading, clothing and airborne parachute, aircraft drag parachute, throwing parachute and sports parachute and other industries. According to the weaving method, it can be divided into twisted rope and ordinary mechanical braided rope. The former does not need a rope core when weaving, and the production method is simple, but it is easy to become a flat belt. Very round. [0003] As a kind of membrane form, hollow fiber membrane is widely used in various fields of membrane separation. However, due to the imperfect preparation process of domestic membranes, the membrane stre...
