Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nonwoven fabric used when transplanting plants.

When planting plants in pots, plaster or pieces of flower pots have been used to fill the drain holes at the bottom of the pot to prevent soil from washing out when watering. These days, hard mesh plastic molded products called pot soles are also commercially available.

However, this traditional method leaves large gaps, and when a transplanted plant is watered, dirt always flows out from the bottom of the pot. In particular, plastic pots with many holes on their uneven bottoms are prone to soil leakage.

This also applies to plastic planters used in place of flowerpots.

Also, when transplanting a tree, etc., it has traditionally been the practice to surround the pot with soil around the tree's roots with a straw vine and tie it with a rope to prevent the soil from falling from the tree's roots. It's getting swollen. This work requires skill, and soil tends to fall off during transport.

As mentioned above, when transplanting plants, if you use the conventional method based on your past experience, it may cause soil runoff,
It cannot be said that protection of plants and dirt caused by falling is sufficient.

According to the present invention, when a nonwoven fabric is used in place of the imported product,
It prevents soil from flowing out and falling, and has the following features.

(a) Although nonwoven fabric has small gaps and is difficult for dirt to pass through, it drains excess water well and has good breathability.

(b) The nonwoven fabric can be cut with scissors to fit the shape of the bottom of the flowerpot or planter, making it large or small.

(c) Non-woven fabric can be used in place of straw mushiro and can be used repeatedly as it is more durable than straw mushiro.

It is also possible to make a bag out of non-woven fabric and wrap the roots in it.

(d) If a thick non-woven fabric is used around the inner surface of the flower pot, it will have an insulating effect and will make it easier to maintain the soil temperature at an appropriate temperature.

The nonwoven fabric used in the present invention is rayon, acetate,
Items made of synthetic fibers, including those that have been heat-treated or processed with synthetic resin. It may be used as it is, or it may be colored ocher or brown, which makes stains less noticeable, or colored in any color.

Synthetic resin processing of nonwoven fabrics is carried out using polyvinyl acetate resin, acrylic resin, synthetic rubber latex, urea resin, melamine resin, etc., and can be processed from soft to hard, from hydrophilic and water-retentive to hydrophobic. It is possible to obtain products with desired properties, even those without water retention.

In general, nonwoven fabrics treated with synthetic resin have increased dimensional stability and durability compared to untreated fabrics, and are often suitable for the purpose of the present invention.

The nonwoven fabric used in the present invention has a thickness of approximately 0.1 mm to 5 mm.
．． 0mm and weighs 20g/m2 to 500g/m2 and cut into appropriate sizes. For example, the bottom of a flower pot can be cut into 5 cm square to 30 cm square, and for transplanting a garden tree, it can be cut into a width of about 90 cm and a length of about 2 m.

The nonwoven fabric used in the present invention is breathable in itself, but if higher breathability is required or if a small amount of soil is allowed to flow out, the nonwoven fabric may be punched or other methods may be used. The size of one hole is 0.01cm2~
One or more pieces of about 3.0 cm2 can be used.

These perforated nonwoven fabrics can be used one by one, or two or more can be used so that the positions of the holes do not overlap.

Examples will be described below.

Examples, 1. A plastic flower pot with a diameter of 15 cmφ and a height of 12.5 cm has a bottom diameter of 9.5 cmφ and a height of 1.5 cm in the center.
0cm, 6.5cmφ, and the major axis is 1.2cm, and the minor axis is 0.7cm at the 7.7cmφ position on the bottom.
There are 8 cm circular drain holes provided at approximately equal intervals, and 9 drain ports each having a diameter of 0.7 cm at approximately equal intervals at positions of 4.0 cm on the surface of the center height of the bottom. In addition, 7 on the bottom
．． The reason why the eight drain holes located at the 7 cm diameter are formed in a circular shape is because the drain holes are located on the slope between the bottom surface and the plane at the center height of the bottom surface.

For flowerpots with uneven bottoms and numerous drainage holes, spunbond nonwoven fabric of 50% polyester and 50% rayon, 1 mm thick and 100 g/m2 in weight, is coated with vinyl acetate water-based emulsion resin. It can be processed with resin and cut into 15 cm diameter pieces to be used as pot soles.

Examples, 2. The inside base of a flat pot with a diameter of 27cmφ and a height of 12cm is 15
cmφ, and there is a 6cmφ hole in the center for drainage.

Cut a polypropylene nonwoven fabric with a thickness of 5 mm and a weight of 450 g/m2 into a size of 12 cm x 12 cm, and punch 4 holes of 0.5 cm diameter diagonally at positions 2.7 cm from each of the four corners. Open it up and use it as the bottom of the pot.

Example. 3 Spunbond nonwoven fabric made of 20% polyester, 10% polypropylene, and 70% rayon, 0.8 mm thick and 110 g/m2 in weight, processed with melamine resin to make it slightly harder, 210 cm x 91 cm or 176 cm x 8
Cut into 5cm pieces and use to make pots when transplanting trees.
