Problems solved by technology

[0002] The core-spun rope is widely used due to its good properties of the inner and outer materials. Therefore, the core-spun rope is an important daily necessities. In the existing core-spun rope, although it has other high-performance However, the disadvantages of existing core-spun ropes are that they are not acid-resistant and alkali-resistant. Corrosion occurs after being eroded by acid and alkali, and the expansion is loose, which affects the quality and appearance of the rope.

Embodiment 1

[0031] 1) Material selection: select polypropylene fiber filaments and nylon fiber filaments with a specification of 1000D;

[0032] 2) Doubling: use 6 polypropylene fiber filaments and make 1 strand, and 5 nylon fiber filaments and make 1 strand;

[0033] 3) Twisted thread: After paralleling, the polypropylene fiber filament and nylon fiber filament are twisted through the twisting machine to form three strands of twisted thread. The transmission belt of the twisting machine is tight and tight, and each filament must be controlled by a tension regulator. Regularly measure its speed and twist, and the twist depends on the size of the rope strands;

[0034] 4) Pre-weaving: The polypropylene fiber filament strands twisted by the twisting machine are pre-woven on the automatic pre-loom, 18 strands are in the S twist direction, and 18 rope strands are in the Z twist direction. A bobbin of the spindle size of a high-speed double braiding machine is used to make the outer casing o...

[0040] 1) Material selection: select polypropylene fiber filaments and nylon fiber filaments with a specification of 840D;

[0041] 2) Doubling: use 6 polypropylene fiber filaments and make 1 strand, and 5 nylon fiber filaments and make 1 strand;

[0042] 3) Twisting: The polypropylene fiber filaments and nylon fiber filaments after paralleling are twisted by a twisting machine to form three twisted threads. The transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator. Regularly measure its speed and twist, and the twist depends on the size of the rope strands;

[0043] 4) Pre-weaving: The polypropylene fiber filament strands twisted by the twisting machine are pre-woven on the automatic pre-loom, 12 strands are in the S twist direction, and 12 rope strands are in the Z twist direction. A bobbin of the spindle size of a high-speed double braiding machine is used to make the outer casing of the rope sheath 1;

[0048] 1) Material selection: select polypropylene fiber filaments and nylon fiber filaments with a specification of 2000D;

[0049] 2) Doubling: use 6 polypropylene fiber filaments and make 1 strand, and 5 nylon fiber filaments and make 1 strand;

[0050] 3) Twisting: The polypropylene fiber filaments and nylon fiber filaments after paralleling are twisted by a twisting machine to form three twisted threads. The transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator. Regularly measure its speed and twist, and the twist depends on the size of the rope strands;

[0051] 4) Pre-weaving: The polypropylene fiber filament strands twisted by the twisting machine are pre-woven on the automatic pre-loom, 16 strands are in the S twist direction, and 16 strands are in the Z twist direction. A bobbin of the spindle size of a high-speed double braiding machine is used to make the outer casing of the rope sheath 1;

Abstract

The invention discloses a waterproof acidproof alkali-proof fiber rope and a production method thereof and relates to the field of ropes. The waterproof acidproof alkali-proof fiber rope comprises a shell (1), a rope core (2) and a waterproof acidproof alkali-proof coating (3). The rope core (2) is disposed inside the shell (1). The waterproof acidproof alkali-proof coating (3) is arranged outside the shell (1). The shell (1) is made by weaving half S-directionally-twisted polypropylene fiber strands and half Z-directionally-twisted polypropylene fiber strands. The rope core (2) is a thermally-set combination of triple strands of nylon fiber filaments. The fiber rope includes the three layers from inside to outside; the process is simple to operate; the fiber rope is fine in water proofing, acid proofing, alkali proofing, corrosion resistance, and safety.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a waterproof, acid-resistant and alkali-resistant fiber rope and a manufacturing method thereof. Background technique [0002] The core-spun rope is widely used due to its good properties of the inner and outer materials. Therefore, the core-spun rope is an important daily necessities. In the existing core-spun rope, although it has other high-performance But the shortcoming that the existing core-spun rope exists is that it is not resistant to acid and alkali, corrodes after being eroded by acid and alkali, and expands loosely, which affects the quality and appearance of the rope. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a waterproof, acid-resistant and alkali-resistant fiber rope and its production method. It has a three-layer structure from the inside to the outside, and the process is simple. It has good...
