A. Technical Field of the Invention The present invention relates to artificial sphagnum moss, and more particularly to artificial sphagnum moss composed of fibers. B. Conventional technology and its problems The demand for natural sphagnum moss, which is used for horticultural purposes such as growing orchids and ornamental plants, has increased recently, and domestic production alone cannot keep up with the demand, and the supply volume is decreasing due to soaring prices. The current situation is that there is a strong demand for an increase from all quarters. However, since it is a naturally occurring product, there is little hope that the supply will increase in the future. Under these circumstances, various types of artificial sphagnum moss have recently been announced and put on the market, but they have a good balance of the properties of natural sphagnum moss, such as excellent bulk, water absorption performance, water retention performance, and breathability. At present, nothing comparable to the natural sphagnum moss has yet been obtained. The basic properties required for horticultural sphagnum moss are not only excellent water absorption and water retention performance, bulkiness, and air permeability, but it is also extremely important to have a structure that does not inhibit the normal growth and rooting of plants. However, it cannot be said that conventional artificial sphagnum moss satisfies all of these required performances in a well-balanced manner. A sheet-like nonwoven fabric made by heat-sealing single fibers to each other is slit and shredded (Japanese Unexamined Patent Publication No. 131318/1982), and a porous material made by foaming a water-absorbing polymer and containing countless fine air bubbles. Artificial sphagnum moss is commonly known as shredded sphagnum moss or aggregates of short fibers of relatively thick denier with fine pores on the surface layer (Japanese Patent Publication No. 40243/1983). Because it has a simple structure, it has excessive bulk and air permeability, and its water absorption and water retention properties, which are essential for sphagnum moss, are far inferior to natural sphagnum moss. In addition, similar to film slits, slits made of fused nonwoven fabric have too high bulk and air permeability, are significantly inferior in water absorption and water retention, and the constituent fibers are fused and fixed to each other. Because it has been
The fine roots of the plant that have penetrated between the fibers are constricted by the constituent fibers, inhibiting the normal growth of the roots, and when replanting the plant, the roots do not easily separate from the sphagnum moss, resulting in severe damage to the roots. It has certain disadvantages. In addition, in the case of artificial sphagnum moss made of porous foam material, it has relatively high bulk, water absorption, and water retention properties, but the fine roots of plants that encounter partially existing closed cells cannot grow and die. In addition to this, it is inconvenient to handle because it lacks the mutual entanglement required for sphagnum moss. The problem with artificial sphagnum moss made from short fibers with microscopic voids on their surface lies in their water absorption performance; simply the total volume of the microscopic voids existing on the fiber surface is not enough to secure and absorb the required amount of moisture for sphagnum moss. I can't. As a result of a detailed study of the structure of natural sphagnum moss, the present inventors found that there are countless huge bag-shaped water storage cells in the parts corresponding to the leaves, and the cells absorb a large amount of water. It has a special structure that lasts for a long time, and the trunk and branches that support the leaves are relatively thick and rigid, giving it superior bulk and air permeability that cannot be obtained from sphagnum moss leaves alone. I have a role to play. By forming such a two-component structure,
For the first time, it was discovered that it satisfies all of the contradictory properties required of sphagnum moss. All currently known artificial sphagnum moss has a single-component structure, and such a structure cannot satisfy all the performance requirements for sphagnum moss in a well-balanced manner. C. Purpose of the present invention From the above viewpoint, we have created a two-component structure that has a water-absorbing/water-retaining component corresponding to the water-storing cells of natural sphagnum moss, and a bulk-height/breathability imparting component corresponding to the trunk/branches. It was found that artificial sphagnum moss with well-balanced performance as sphagnum moss can be obtained.
The present invention was achieved by confirming this through experiments. That is, an object of the present invention is to provide an artificial sphagnum moss that satisfies the properties required for sphagnum moss in a well-balanced manner, does not inhibit plant growth, and is easy to handle. D. Configuration of the present invention The object of the present invention is achieved by the following configuration. (1) A fiber aggregate with a particle size of 15 mm is made of short fibers that are interconnected so that they can move relatively freely.
An artificial sphagnum moss formed by mixing and entangling the following granular entangled short fibers formed by entangling the short fibers with each other. (2) The artificial sphagnum moss according to claim 1, wherein the fiber aggregate is composed of short fibers having a single fiber denier of 5 denier or more and 80 denier or less. (3) The short fiber granular entangled body has a single fiber denier of 5.
The artificial sphagnum moss according to claim 1, which is made of short fibers of denier or less. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a model diagram for explaining the artificial sphagnum moss according to the present invention, and FIG. 2 is an enlarged diagram of a granular entangled body made of short fibers. In the figure, reference numeral 1 indicates a granular entangled body that constitutes the water-absorbing and water-retaining component, which is composed of relatively fine denier short fibers 3, and is formed by entangling each of these short fibers. It is a fiber aggregate, and inside it has countless microscopic spaces formed by a large number of intertwined fibers. Due to this structure, moisture is drawn into the microscopic spaces by capillary action, and the moisture in the fiber aggregate becomes like a single water droplet. Therefore, inhaled moisture is retained for a relatively long period of time.
It has properties suitable for sphagnum moss. The short fibers 3 constituting the granular entangled body can be natural fibers, man-made fibers, synthetic fibers, water-absorbing fibers, as well as fibers with high shrinkage caused by heat or fibers that develop shrinkage, but from the viewpoint of corrosion resistance, Synthetic fibers are preferred. Of course, these fibers may be used alone or in combination. Furthermore, short fiber 3
When short fibers having hydrophilic or water-absorbing properties are used, further water-absorbing and water-retaining effects can be expected. As for the thickness of the short fibers used here, it is preferable that the short fibers be thinner, as this will result in the formation of small and large numbers of microscopic spaces; if the short fibers are too thick, the formed spaces will be coarse, and the effect of capillary action will not be exhibited satisfactorily. , water absorption and water retention performance decreases. Therefore, the appropriate thickness of the short fibers is 5 deniers or less, preferably 3 deniers or less. There is a nearly constant relationship between the thickness of the short fibers used here and the average particle diameter of the granular entangled bodies formed thereby, and if the thickness of the short fibers is d denier, then The average grain size Dmm of the granular entangled bodies thus formed is in the relationship D=3×d. Therefore, when d is 5 deniers or less, the average grain size is 15 mm or less. The short fibers should preferably have a large number of crimps and be fine in order to form fine spaces, and suitably have a degree of crimping of 15% or more and a number of crimps of 15 threads/25 mm or more. When forming such short fibers into small lumps,
In order not to inhibit the normal growth of plant roots, strong adhesion methods such as heat fusion between fibers or adhesives should be avoided. It is necessary to have a structure that allows the single fibers to move relatively freely. The artificial sphagnum moss according to the present invention is produced by mixing the water-absorbing/water-retaining component 1 made of entangled particles in the form of small particles with the fiber aggregate 4 made of relatively thick and rigid short fibers, and entangling the two. By combining and interlocking, the sphagnum moss has an integral structure and is given the required bulk and air permeability. Here, the short fibers constituting the fiber aggregate 4 include various natural fibers, artificial fibers, synthetic fibers, water-absorbing fibers, and highly shrinkable or shrinkable fibers developed by heating, in the form of single short fibers. , or can be used in combination, and the thickness of the single fiber used for this is 5 deniers or more, 80
Denier or less is appropriate. If it exceeds 80 denier, it is difficult to intertwine and link, and it is meaningless as a linking fiber. Moreover, if it is less than 5 denier, the bulkiness will be lowered. When forming an integral structure consisting of or mainly consisting of the granular entangled bodies 1 and the rectangular fibers 4 as described above, the interlocking means of the granular entangled bodies 1 and the finite long fibers 4 are necessary. Adhesion using adhesives or heat fusion fixes the fibers and inhibits the free movement of single fibers, which is unfavorable for plant growth. A monolithic structure is formed by intertwining the interconnected fibers, but to further improve the bulk, heat treatment using wet heat or dry heat is also possible, and if stronger shape retention is required, a separate The interconnected fibers can be tied together using knitting thread or sewing thread, or the intertwining of interconnected fibers can be made stronger using needles, or this integrated structure can be formed into a sash-like shape to produce 30T/M. It is also possible to add the following twists. In the artificial sphagnum moss according to the present invention, the proportion of the small aggregate fiber aggregate to the total weight is 5% or more in order to provide the desirable bulkiness, water absorption, water retention, and air permeability for sphagnum moss in a well-balanced manner. An appropriate range is 90% or less, preferably 10% or more, and 80% or less. If it is less than 5%, the bulk is high, but the breathability is excessive, and the water absorption and retention performance is not satisfied, resulting in frequent watering. Requires. If it exceeds 90%, water absorption and water retention will be excessive, and bulkiness and breathability will be insufficient, leading to root rot, which is not desirable. E. Effects of the present invention As described above, the artificial sphagnum moss composition according to the present invention has an integrated structure of two components: small aggregate fiber aggregates as a water absorbing/water retaining component, and fibers connecting these as a bulk retaining component. It is an artificial sphagnum moss, and with such a structure, the water absorption and water retention properties necessary for sphagnum moss are achieved by the small aggregated fiber aggregates, and the bulkiness and air permeability are achieved by the interconnected fibers. Furthermore, since the constituent single fibers are bonded by entanglement, the single fibers can move relatively freely and do not inhibit root growth, making it an ideal artificial sphagnum moss. Furthermore, in order to further increase the added value of sphagnum moss, appropriate antibacterial agents, insect repellents, water absorbing agents, etc. are added to prevent the proliferation of pests and bacteria, or to further improve water absorption performance. It is also possible. The two-component integrated structure according to the present invention can be made into any form that is easy to use as sphagnum moss, such as a pine-like shape, a rod-like shape, a slitted ribbon-like shape, or a shredded small-sized lump-like shape. It is ideal for cultivating flower petals or ornamental plants. The present invention will be specifically described below based on Examples.
The bulkiness described here is the volume per 1g of sphagnum moss expressed in cm 2 under a load of 11g/cm 2 , and the water absorption capacity is the amount of water absorbed relative to the bone dry weight of sphagnum moss expressed as a ratio. It is something. Further, the water release rate is the amount of water reduced after being allowed to stand for 5 days after water absorption, expressed as a percentage of the initial water amount. Furthermore, the solid phase rate, liquid phase rate, and gas phase rate are the volume ratios occupied by sphagnum moss, moisture, and air relative to the total volume after water absorption by sphagnum moss, expressed as percentages, and the liquid phase rate is 55~
65%, and a gas phase ratio of 35 to 45% is an appropriate range. Example 1 Short polyester fibers with a thickness of 0.8 denier and a length of 30 mm were entangled to make a granular entangled body with an average diameter of 2.4 mm, and this was used as water absorption/water retention component A.
Polyester short fibers with a denier and a fiber length of 70 mm are used as bulk component B, and both components are mixed at a weight ratio of 50%.
A web with a basis weight of 100 g/m 2 was produced using a card machine, and this was cut into ribbons of 20 mm in width and 100 mm in length to obtain artificial sphagnum moss according to the present invention. On the other hand, we prepared 100% component A and 100% component B, added natural sphagnum moss to these three types of artificial sphagnum moss, and compared and evaluated the performance of the sphagnum moss. Table 1 shows the results.

[Table] When component A is 100%, water absorption and water retention are excessive.
The vapor phase ratio is extremely low, and root rot occurs with only component A. Those containing 100% B component have a high gas phase ratio, low liquid phase ratio, and low water absorption capacity, and require frequent irrigation, making them unsuitable as sphagnum moss. In contrast, the product of the present invention had good water absorption capacity, liquid phase ratio, and gas phase ratio. Example 2 Cotton fibers were entangled to create a granular entangled body with an average diameter of 4 mm, which was used as component A, and 30% polyester staple fibers with a thickness of 6 denier and a fiber length of 70 mm.

A sliver of 40 g/m 2 was spun. From this sliver, roving yarn with a basis weight of 2 g/m 2 and a number of twists of 10 times/m was prepared, and this was cut into pieces of about 7 cm length to obtain artificial sphagnum moss according to the present invention. On the other hand, rovings were prepared using 100% B component under the same conditions and cut into approximately 7 cm pieces, and the results of a comparative evaluation of three types including natural sphagnum moss are shown in Table 2.
