Description

[Detailed Description of the Invention] The present invention relates to a one-trick water supply rod M***Hatazukuri**, and more particularly, it is made of a fiber molded body whose form has been stabilized by heat Il & 1liI of heat-adhesive rings. Yugei water supply stick※na※※
*It is related to the Qin jar *Dake*.

When cultivating parent prize plants and home garden vegetables using flowerpots, irrigation work requires careful attention and is an essential daily task, especially for professionals who manage a large number of pots. The effort is also a big burden. For this reason, methods have been devised to continuously supply a suitable amount of water to a flowerpot.2For example, a flowerpot is placed on top of an aquarium, and a cloth or paper rolled up into a stick is inserted into the drainage hole of the flowerpot and then placed in the wick of a lamp. There is a method of supplying water from an aquarium to a flower pot using the following method.

However, cloth and paper are not made of a constant material, require work to be formed into a rod shape, and the shapes and hardness of the formed pieces vary, making it inconvenient to insert into the drainage hole of a flower pot, and not only does it guarantee a certain water supply capacity. In addition, there are drawbacks to rice, such as the risk of it rotting and disappearing during use.

It is also known that cellulose acetate twill tow is formed into a rod shape and used as a water supply rod.

In this case, it is convenient to install flower pots, etc., but it swells with water during use, making the shape unstable and rotting if used for a long time.The water supply capacity is also inconsistent, making it difficult to use apricots. It has the disadvantage of an unbearable cape.

The purpose of this defense is to eliminate the above-mentioned drawbacks of conventional water supply materials.

The purpose is to provide a water supply system for gardening that has a stable form, a high water supply capacity, and can withstand repeated use for a long period of time.

The gardening monthly watering rod of the present invention is made of heat-fusible fibers or mixed fibers with other fibers containing 40 weight or more of heat-fusible fibers, and the shape is changed by heat-fusion of the heat-fusible fibers. It is a stabilized round rod-shaped molded product.

The monthly water supply rod for gardening is characterized by a porosity of 70 to 80 valence inside the hollow molded product.

The heat-fusible fibers used in the present invention are fibers made of a fibril-forming thermoplastic resin, and examples of such thermoplastic resin include polyethylene.

There are resins such as polypropylene, polybutene, ethylene-vinyl acetate copolymers and saponified products thereof, polyesters, polyamides, comonomers containing these resins as main components, and mixtures of these resins. The heat-fusible fiber may be a single-composition fiber made of only one of the above-mentioned thermoplastic resins.

Alternatively, it may be a fused ring composed of a plurality of components. This is because the heat-fusible fiber can be heat-treated at a temperature below the melting point of two components with a melting point difference of 10°C or more, and melt bonding can occur at the contact point of the low-melting component while maintaining the overall fiber shape. 1. A rod-shaped body with high elasticity and high porosity can be obtained.

The heat-transmitting fiber is formed into a water-absorbing rod by itself or in combination with other gauze fibers. Other fibers preferably include fibers having a melting point higher than the heat treatment temperature during molding.9 For example, natural fibers such as cotton, linen, and wool.

Examples include chemical fibers such as rayon and acetate, as well as 1% inorganic fibers such as glass powder and asbestos.

When used in combination with these other fibers, it is preferred that the mixed fibers contain 40 or more heat-fusible fibers for reasons such as ease of molding and stability of the shape of the molded material.

The water absorption and elongation properties of this @mei are filaments of the heat-adhesive mackerel fibers or a mixture of heat-adhesive fibers and filaments.

The appropriate amount of tow or sliver is collected so that the desired thickness has a porosity of 70 to 90%.

The heat-adhesive mackerel fibers are fused and dusted by heat treatment to form a rod-shaped body with a stable shape, which is then cut into a desired length.

The performance of the water supply rod of the present invention is the water absorption power due to the capillary phenomenon of the l11 fiber peak and the water retention power of the space created at the fusion point.

Furthermore, it is based on hardness and elasticity suitable for use. When the porosity inside the water supply rod is less than 10%.

The water permeation resistance is large, and the water supply capacity is reduced because the wire gaps are easily blocked by foreign matter.Also, in the case of thick water supply rods, heat transfer to the center of the rod is likely to be insufficient during molding. Processing becomes difficult. If the porosity exceeds 90, capillary phenomenon occurs in the fiber gaps, resulting in poor water supply ability, and in extreme cases, no water can be absorbed at all. In addition, the water supply rod is not hard enough, making it difficult to push it into a flowerpot, making it inconvenient to handle.

As a molding method, any of the methods shown in Japanese Patent Publication No. 45-5439 or Japanese Patent Application Laid-Open No. 55-6'7415 can be used, but the method using a heated mold by Curver causes thermal fusion to the surrounding surface of the fiber bundle. Easy to concentrate and form a shell.

On the other hand, the fusion bond in the center part is weak, so fibers may fall off during use. The surface of the rod has poor water permeability, and water absorption from the aquarium and water supply into the soil of the flower pot are both performed through the cut end of the fiber bundle, which tends to result in poor water supply ability. In the latter method, the fiber bundle is exposed to a heated air stream and then closely molded in a mold, so that uniform heat fusion occurs to the center of the rod-shaped body, the shape is stabilized, and a shell is formed on one surface. Therefore, it is possible to obtain a rod-shaped body with a large water supply capacity.

The water supply rod of the present invention utilizes the capillary 1f phenomenon of the line gap as described in a, and once the water supply rod is filled with water, a continuous water supply action is maintained. However, if the shell is mainly composed of hydrophobic fibers, the suction capacity may be insufficient at the beginning of use. In such cases, it can be used by pre-impregnating it with enough water, but it is also effective to add a layer of surfactant to the surface of the hydrophobic fibers to improve the water supply capacity. . Methods for attaching the surfactant include a method of impregnating a surfactant solution in a water supply tube, a method of applying a surfactant to the fiber when producing the hydrophobic fiber, and a method of applying the surfactant to the fiber when producing the hydrophobic fiber. Any method can be used in which a surfactant is kneaded into the thermal tlTwIi resin as a raw material during spinning of the fiber.

Even if the amount of surfactant sealed in the water supply rod is 0.23 or more, it exhibits excellent water absorption.

Hereinafter, the present invention will be specifically explained with reference to Examples. The planning method for water supply 1- shown in the example is as follows.

1. Water absorption capacity: Fill a water tank with water colored with red ink, and dip the bottom end of a water supply rod held vertically to a depth of 20 mm. Measure the height from the water surface to the top of the colored part colored by the water sucked up by the water supply rod. Those with a height of 130 mm or more after 60 minutes are considered acceptable.

2.ftI! A: After submerging the water supply rod in water for an hour, test the hardness by picking it up with your fingers. Three levels of 1 valence were performed.
