Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to synthetic fibers for fishery industry materials, particularly synthetic fibers for fishery materials such as fishing nets, ropes for fishing nets, p-builds for mooring, etc. that have less adhesion of seaweed. Regarding.

BACKGROUND OF THE INVENTION It is well known that seaweed, shellfish such as Fujitbo and mussels adhere to and accumulate on fishery materials, causing various problems.

Conventionally, as a synthetic #fiber for fishery industry materials, Naipun! Fibers or molded products made of various synthetic fibers such as vinylon, polyvinylidene chloride, polypropylene, and polyester are used.

However, seaweeds including diatoms also adhere to fishery materials made of these synthetic fibers 9 synthetic resin molded products, reducing the performance of the fishery materials. Therefore, the development of synthetic fibers for fishing nets and other fisheries materials that can prevent seaweed from adhering to water is highly desired. Therefore, conventional methods of treating synthetic fibers using antifouling agents to prevent the adhesion of seaweed, methods of blending agents with antifouling effects into polymers that make up synthetic fibers, or methods of mixing and twisting metal wires with synthetic fibers have been proposed. Several methods have been proposed. However, the method of treating with an antifouling agent has poor adhesion between the synthetic fiber substrate and the antifouling agent.

The method of blending an antifouling agent with a polymer has the problem of the heat resistance of the antifouling agent itself. The method of mixing and twisting metal wires with synthetic fibers has the drawback that the modulus of the metal wires and the modulus of the synthetic fibers are extremely different, making it unavoidable to make the product non-uniform, so it is not recommended.

Therefore, the present inventors have conducted extensive research in order to provide synthetic fibers for fishing nets, polypropylene, and other fishery materials that do not have the above-mentioned drawbacks and can prevent seaweed from adhering to them. We have succeeded in developing a synthetic 9' string for fishery materials that has excellent adhesion and durability to materials and can prevent seaweed from adhering to it, leading to the present invention.

The structure of the invention, that is, the present invention is based on the following: A synthetic fiber for fishery industry materials in which an oxide of one or more selected elements and an oxide of tin are adhered to a textile surface using a water-soluble adhesive.

(2: Oxide is aluminum, silica, titanium.

The synthetic fiber for fisheries materials according to claim 11, which is an oxide of one or more elements selected from the group consisting of zirconium and an oxide of tin.

(3: Claim 01 or (2) in which the fiber is a fiber made of a linear aromatic polyester whose main constituent is a repeating unit represented by the general formula (n is an integer a of 2 to 6) "Synthetic fibers for fisheries materials as described in Section 1."

Here, the elements in the 3rd, 4th, and 5th period K14-f of group 111 in the periodic table of elements are aluminum, gallium, indium, etc.
The elements in the period, 4th period, and 5th period K14 are silicon,
These include titanium and zirconium. Elements that fit into the fourth period of the group include cobalt, nickel, and the like.

Oxides of one or more elements selected from these element groups are
As for oxides, the number of bonded oxygen atoms is not limited.

However, although only a tin oxide may be used, when an oxide of an element other than tin is used, it is essential that a tin oxide be present together. Fibers are polypropylene fibers, polyamide fibers,
It is also possible to use polyvinyl alcohol fibers, aramid fibers, polyester fibers, or a combination thereof, but it is preferable to use polyester fibers because of their excellent versatility.

In the present invention, the linear aromatic polyester specifically refers to a bifunctional aromatic acid such as terephthalic acid, isofucric acid, naphthalene dicarboxylic acid, diphenyl dicarboxylic acid, etc. as an acid component, and ethylene glycol, Examples include polyester 7T whose glycol component is a glycol such as trimethylene glycol, tetramethylene glycol, or hexamethylene glycol. Preferably, polyester is used as a t filter constituent component, and in particular, 7I whose main glycol component is at least one glycol selected from ethylene glycol and tetramethylene glycol.
(Esters are preferably used.

Such polyesters may have some of their acid components replaced by other difunctional carboxylic acids.

Examples of such other carboxylic acids include carboxylic acids other than the above-mentioned carboxylic acids used as the main component, such as terephthalic acid and inphthalic acid.

Naphthalene dicarboxylic acid, diphenyl dicarboxylic acid, diphenoxyethane dicarboxylic acid! Difunctional aromatic carboxylic acids such as β-oxyethoxybenzoic acid, pi-oxybenzoic acid, difunctional fatty acid carboxylic acids such as sebacic acid, adipic acid, oxalic acid, or 1,4-cyclohexanedicarboxylic acid. Examples include difunctional alicyclic carboxylic acids such as. Further, a part of the glycol component of the polyester may be replaced with another glycol component, and such glycol components include the above-mentioned glycol and other diol compounds other than the main component, such as cyclohexane-1,4-dimethanol, neopentyl glycol, bisphenol, etc. Examples include aliphatic, alicyclic, and aromatic diol compounds such as t''A+bisphenol S.

In the periodic table of elements, the 3rd, 4th, and 5th period of Group 1 or Group 1 or the 4th period of Group 4 FcJ
The following methods can be used to attach oxides of elements selected from the group consisting of elements Ii and oxides of tin to the fiber surface on 7t'lJM.

The simplest method is to apply the oxide powder to the yarn immediately after spinning without solidifying it, or to apply a spinning hindlimb oxide dispersion to the yarn. However, there are problems in that the oxide powder causes yarn breakage, fuzz, etc. in the silk reeling process after spinning, and the oxide easily separates from the fibers, making it impossible to obtain the expected effect, making it impractical. .

In the present invention, a synthetic fiber for fisheries materials having a nucleic oxide on the surface was obtained by the following method.

First, the surface of the #l fiber is degreased in a conventional manner.

Next, 7 minium and zirconium! For example, a water-soluble adhesive having an epoxy group is added to a mixed solution of an aqueous solution of an alkoxide such as titanium 9 silicon and an aqueous solution of a tin alkoxide, and then an acid is added to hydrolyze the alkoxide. Spraying the resulting aqueous solution onto defatted fibers,
It is applied and heat treated according to a conventionally known method such as a coating method or a dipping method. As a result, a gel-like polymer of 311 oxide is applied to the surface of the gauze together with a water-soluble adhesive having an epoxy group.
Fixed.

The number degree of the fiber used in the present invention is preferably in the range of 0.5 to 20 deniers in terms of single yarn steepness, particularly 1.5 to 20 deniers.
A range of 15 denier is preferred. If the single yarn steepness is less than 0.5 denier, it is not preferable because fuzz and single yarn breakage are likely to occur during the spinning process. If it exceeds 20 denier, it becomes difficult to twist yarn, S-net, etc., so it is not preferable.

Effects of the Invention As a result of the construction as described in detail above, when the synthetic fiber for fishery industry materials of the present invention is used to make fishing nets and ropes, the anti-algae effect is significantly superior to that of conventional products.
