Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a rope having high strength, antifouling properties and water absorption properties and excellent durability.

[0002]

2. Description of the Related Art Conventionally, synthetic fiber ropes such as polyester fibers and polyamide fibers have excellent wear resistance, cold and heat resistance, strong physical properties, and fatigue resistance, so that they can be used for fishing materials such as seine nets, seine nets, and fixed nets. It is widely used as ship materials such as suspending ropes, construction materials such as safety nets, civil engineering materials, and packaging materials. These are often used outdoors, and their physical properties are deteriorated by the effects of sunlight, wind and rain, seawater, cement and the like. Among these, the influence of water is also great. That is, due to the influence of water, the synthetic fibers are hydrolyzed to deteriorate the physical properties, soiled due to the attachment of dirty water, mold is generated, and the absorbed water is frozen and deteriorates in cold regions. Further, in the above-mentioned material field, it has become a problem in terms of working conditions that the rope becomes heavy due to water permeation and becomes difficult to handle.

Generally, in the case of a fiber cloth, a water absorption preventing property is imparted by a method of immersing the cloth in a bath of a fluorine compound or a silicon compound, squeezing it with a mangle or the like to adhere a predetermined amount, and then heat treating it. However, even if this method is applied to the rope, it cannot be processed by infiltrating even into the twisted inside, and after the treatment only on the very surface of the rope, the water absorption prevention performance is evenly distributed over all the monofilaments constituting the rope. Cannot be given.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation as described above, and prevents the generation of dirt and mold due to the adhesion of water, and the weight due to the penetration of water into the interior. The purpose of the present invention is to provide a rope with excellent durability that does not increase or freeze.

[0005]

The present invention achieves the above object and has the following structure. That is, according to the present invention, the strength is 7 g / denier or more, and the perfluoroalkyl group-containing compound is 0.1 to 0.1 with the spinning oil agent.
Made of synthetic fiber with 3.0% added, then 13
The gist of the present invention is a rope manufacturing method characterized by heat treatment at a temperature of 0 to 200 ° C.

The present invention will be described in detail below. In the present invention, a synthetic fiber having a strength of 7 g / denier or more is used. Synthetic fibers include polyester fiber, polyamide fiber,
Polyolefin fibers, polyvinyl alcohol fibers, etc. are used, and among these, aromatic polyester fibers, aromatic polyamide fibers, highly oriented polyolefin fibers, highly oriented polyvinyl alcohol fibers, etc. are also suitably used. Also,
As the polyester fiber, a fiber containing polyethylene terephthalate as a main component, and a polyester fiber obtained by copolymerizing a third component to the extent that the characteristics of polyethylene terephthalate are not impaired can also be used. Regarding polyamide fiber, nylon 6, nylon 66, nylon 4
It is possible to use a polyamide fiber containing 6 or the like as a main component, and a polyamide fiber obtained by copolymerizing a third component to the extent that the characteristics are not impaired.

The strength of the synthetic fiber used in the present invention must be 7 g / denier or more. When the strength is less than 7 g / denier, when the rope made of the fiber is used as a fishing material, a ship material, a construction material, a packing material, etc., the strength is insufficient, and a product satisfying the required characteristics for each application is obtained. I will not be able to.

The synthetic fiber used in the present invention is spun from a spinning section through a nozzle, and after cooling or spinning solution removal,
It is introduced into an oil agent applying device to apply a perfluoro group-containing compound together with a spinning oil agent. The spinning oil agent in the present invention means a normal oil agent containing a smoothing agent, an emulsifying agent, an antistatic agent, and the like, and the smoothing agent includes mineral oil, fatty acid esters, etc., and the emulsifying agent includes higher alcohols or ethylene oxide. There are (EO) adducts and the like, and as the antistatic agent, various surfactants such as anionic and cationic surfactants are used.

The perfluoroalkyl group-containing compound is generally used as a water / oil repellent agent, and is a perfluoroalkyl group-containing acrylic acid ester / methacrylic acid compound / urethane compound or the like.
From the viewpoint of heat stability and performance, 1,3,5-tris (6-isocyanate hexyl) buret has 2-
{(Perfluoroalkyl (C ₆ -C ₁₈ ))} ethanol, 1 octadecanol, 2,3-epoxy-1-propanol adduct and derivatives thereof are suitable, and even if these compounds are used alone. , May be used in combination.

The total amount of the spinning oil and the compound containing the perfluoroalkyl group is 0.2 to 5% by weight, and the amount of the compound containing the perfluoroalkyl group is 0.1 to 3% by weight. Is. If the amount of the perfluoroalkyl group-containing compound applied is less than 0.1% by weight, sufficient water absorption preventing performance cannot be obtained. On the other hand, if the applied amount exceeds 3% by weight, stable winding on the bobbin during fiber production is difficult.

Although the spinning oil agent and the perfluoroalkyl group-containing compound may be mixed in advance and applied simultaneously, a one-step application method may be used. However, the spinning oil agent is first applied and then the perfluoroalkyl group-containing compound is applied in two steps. The grant method may be adopted. When the spinning oil and the perfluoroalkyl group-containing compound are applied at the same time, it is important to select a compatible agent that does not cause precipitation or the like.

After the spinning oil agent and the perfluoroalkyl group-containing compound have been applied, they are introduced into a hot drawing step and heat-fixed. The heat-fixing method is a method of contacting with a hot roller or a hot plate.
Any method of allowing the yarn to pass through the heating atmosphere may be used.
In addition, the heat treatment is not sufficient in the fiber manufacturing process, and the water repellency is insufficient at the raw yarn stage, but the heat treatment performed to stabilize the shape, quality, and performance of the rope after rope making It is also possible to exhibit water repellency.

In the present invention, various types of ropes are adopted according to the intended use, and the ropes are made by making the above synthetic fiber yarns by a conventional method. That is, it is first twisted by a ring twister or the like, first twisted by a flyer twister or capsten twister, made into strands by a strander, and ropes by a closer or knitting machine.

The rope made of rope is heat-treated in order to stabilize its shape, quality and performance. As a heat treatment device,
Although various methods such as high-frequency heat treatment and infrared heater can be used, the heat treatment temperature is set to 130 to 200 ° C. The heat treatment temperature is set to 130 to 200 ° C. so that the water-repellent performance of the perfluoroalkyl group-containing compound provided at the time of fiber production can be sufficiently exerted. When the heat treatment temperature is less than 130 ° C., satisfactory water repellent performance can be obtained. I can't. 200
Water-repellent performance is sufficient when heat-treated at a temperature above ℃,
Problems such as deterioration of fiber performance will occur.

[0015]

According to the present invention, since the synthetic fiber having a strength of 7 g / denier or more is used, a rope having strong properties suitable for each application can be obtained, and a perfluoroalkyl group-containing compound is added together with a spinning oil agent. Since heat treatment is performed at 130 to 200 ° C. using the synthetic fiber described above, it is possible to impart water repellency to individual fibers constituting the rope,
Sewage does not adhere and become dirty, and mold does not occur, and moisture does not penetrate into the rope due to the capillary phenomenon, so that workability deterioration due to weight increase and deterioration due to freezing hardly occur.
