CONSTITUTION:The objective material is a water-soluble cloth (e.g., cloth of carboxymethylcellulose sodium salt) which can be dissolved essentially within 5min in seawater. A fishing bait attached to a fishing hook is wrapped or covered with the cloth to hide said bait from small fish until the bait reached the swimming layer of the objective fish. The fishing bait is protected by the material from external force applied to the bait in spinning, etc., and from small fish swimming in the surface layer or the middle layer.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a protective material for fishing bait in fishing or recreational fishing. More specifically, the bait attached to the hook is coated and coated to the depth layer where the target fish swims.
This invention relates to a protective material for fishing bait that hides and protects it from being eaten by small fish on the surface.

(Prior art) In fishing or recreational fishing, high quality fish and large adult fish swim in relatively deep areas such as ditches or lakes (hereinafter referred to as the sea), so it is necessary to insert the hook to the depth where the target fish swims. It needs to sink.

However, until the hook sinks to the desired depth, there are many small fish of low commercial value, such as young mackerel, swimming in the surface and middle layers, and there is a problem that they steal expensive bait and eat it. So far, no effective means of defense has been found.

Furthermore, in cast fishing, there is also the problem that soft bait such as a bait may come off the hook due to the impact when throwing out the hook, air resistance in the air, or even the impact when landing on the water.

(Problems to be Solved by the Invention) The purpose of the present invention is to solve such problems related to baits for fishing. To protect the bait from small fish (hereinafter referred to as small fish) and deliver the bait attached to the hook to the fish swimming in the deep sea (hereinafter referred to as target fish); to spin the bait that falls off the hook during cast fishing; The purpose is to provide materials that protect fishing bait until it reaches the target fish.

(Means for Solving the Problems) The present invention is a fishing bait protection material that is wrapped around or covered with a fishing bait attached to a fishing hook to hide the bait from minor fish until it reaches the swimming layer of the target fish. 5 when the material is in seawater
A protective material for fishing bait characterized by comprising a water-soluble fabric that substantially dissolves within minutes.

It is important that the fabric forming the protective material of the fishing bait of the present invention is water-soluble, and is completely dissolved or almost completely dissolved within 5 minutes in seawater at the latest. As a result, the fabric shape is no longer recognized, the bait is exposed, and the odor and appearance of the bait are effective enough to attract the target's interest.

If it takes longer than 5 minutes, fishing results tend to deteriorate, perhaps because the exposure of the bait is delayed, which reduces the efficiency of fishing, or because the diffusion of the scent of the bait is inhibited.

Of course, it is not necessary that the entire protective material be completely dissolved;
Even if there is a partially dissolved residue, the effects of the present invention can be obtained as long as the fabric substantially loses its form.

The lower limit of the dissolution time varies greatly depending on the thickness of the swimming layer of small fish, the speed of the ocean current, the size of the weight, etc., but the objective of the present invention can be achieved if it is approximately 10 seconds or more.

Water-soluble fabrics include fabrics made of carboxymethylcellulose-sodium salt (hereinafter abbreviated as CMC-Na), polyacrylamide, acrylate-acrylonitrile copolymers, or copolymers of these with other comonomers. Fabrics consisting essentially of water-soluble polymers and other water-soluble polymers are preferably used.

In addition, the shape of the fabric includes knitted fabric, non-woven fabric,
Its form is not limited as long as it does not impair the effects of the present invention, but since it is intended for such disposable and consumable use, it is preferable to be inexpensive, and in that sense nonwoven fabric is preferable. Further, since the fabric is less likely to be damaged during coating, long-fiber nonwoven fabrics are more preferable because they tend to exhibit yarn strength.

A method for manufacturing these water-soluble fabrics is disclosed in Japanese Patent Application Laid-Open No. 62-1
No. 5318, as in other methods, acrylic acid and acrylonitrile are copolymerized, or as in JP-A No. 6, No. 77313, an acrylic polymer is partially hydrolyzed to modify it into an acrylic acid-acrylonitrile copolymer. The fibers obtained by spinning the water-soluble polymer can be further knitted or woven, or the fibers obtained by spinning the water-soluble polymer can be further knitted or woven, such as by spinning the water-soluble polymer and then neutralizing it to make water-soluble fibers. It can also be provided by processing the cellulose fiber fabric into a non-woven fabric using the method described above, but more conveniently, CMC-Na A method of modifying a fabric made of acrylic fibers into an acrylate copolymer by partially hydrolyzing it, then neutralizing it by applying other methods disclosed in JP-A-57-77313. It can be manufactured by

There are no particular restrictions on the thickness of the fabric,
It may be arbitrarily determined based on the dissolution rate of the fabric in seawater and the strength required for the fabric. Also, in actual use,
These requirements can be easily adjusted by using an appropriate number of layers.

The protective material may be of any type as long as it can cover the entire fishing hook with the bait attached and hide the bait from small fish.
For example, it is preferable to use a bag-like bag in which the fishing hook and bait can be stored, and if necessary, secure the bag by tying off the entrance. Also, considering the labor cost of processing it into a bag,
The purpose of hiding fish from small fish can also be achieved by wrapping or wrapping them around fishing hooks and bait in the form of bandages, triangles, or furoshiki.
This is a more preferable embodiment because it can be freely adapted to the size and shape of the bait, wrapped around it like a bandage for the required length, and cut at any point. In any case, the form of the protective material is not essential and is not particularly limited in order to achieve the purpose of the present invention.

(Function) According to the fishing bait protection material of the present invention, while the fishing bait is wound or wrapped together with the fishing hook in the protection material and the protection material maintains the form of a fabric, external forces acting on the fishing bait during cast fishing etc. While the bait is settling, it is protected from small fish that attack it, and the material dissolves and disappears for the first time while it settles in seawater, allowing it to be safely delivered to the target fish as bait.

(Examples) Specific embodiments of the present invention will be described below with reference to Examples, but it goes without saying that the present invention is not limited only to the Examples.

Example 1 100 g of bleached cloth, which is a commercially available cotton cloth, was
5458, in an 85:15 (volume ratio) mixture of 2-propanol and water containing 0.6% by weight of chloroacetic acid and IJium hydroxide, respectively.
The mixture was reacted at 65°C for 90 minutes to form CMC-Na, then washed with a mixture of methanol and water at a ratio of 80:20 (volume ratio), further replaced with methanol, and then dried to obtain a degree of substitution of 0.35. A CMC-Na woven fabric was obtained.

When this cloth was immersed in seawater collected from the Hyuganada Sea and adjusted to 20°C, it was confirmed that it was almost completely dissolved in about one minute.

Example 2 Superlab (trademark of Asahi Kasei Industries, Ltd.), which is commercially available as a long fiber nonwoven fabric of CMC-Na, was cut into a bandage shape with a width of 5 mm and was actually attached to a fishhook. The bandage was wrapped in three layers so that the entire area was covered, and the ends of the bandage were torn to form two strings and tied to prevent the bandage-like protective material from unraveling.

When the offshore net coated with the protective material of the present invention was immersed in the seawater of Example 1, it was demonstrated that the protective material dissolved in about 5 minutes and the offshore net was exposed. .

Example 3 The commercially available CMC-Na nonwoven fabric used in Example 2 was sewn into a bag shape with an entrance width of 6C:m and a depth of 8cm, and the Oki net used in Example 2 was attached to the needle inside. When I inserted the object, tied the entrance with a string, and immersed it in seawater in the same way, about 1
The CMC-Na nonwoven fabric was dissolved in minutes, and the bottom layer was exposed.

Example 4 In place of the CMC-Na nonwoven fabric of Example 3, a plain woven fabric of acrylic fibers was hydrolyzed and then neutralized in accordance with the method disclosed in JP-A-57-77313 to reduce sodium acrylate to approx. A copolymer containing 35% was prepared, and in the same manner as in Example 2, it was cut into a bandage shape and wrapped around an oki net attached to a needle.

When this protected fishing bait was attached to a No. 4 weighted line and cast with a cast fishing rod to the ground at a distance of 50n+, it was affected by the impact of the casting, air resistance in the air, collision with the ground, etc. It withstood well and was not damaged at all.

For comparison, when a similar test was conducted using unprotected fishing bait, Okiami came off the bait.

(Effects of the Invention) According to the present invention, the bait attached to the hook is protected from external forces acting on the bait during cast fishing, etc., and from small fish that attack the bait while it is settling, and is safely delivered to the target fish as bait. This makes it possible to improve fishing performance.
