Embodiment 1、 comparative example 1

[0041] [Example 1, Comparative Example 1: multilayer sheet for agriculture and gardening]

[0042] (test 1)

[0043] Various crops were cultivated on the farm using an agricultural multilayer sheet made of Japanese paper yarn (Example 1) or an agricultural multilayer sheet made of polyethylene (Comparative Example 1), and the growth state, Chlorophyll content, biodegradability in crops.

[0044]

[0045] The Japanese paper made from Manila banana is cut into 2.0mm width, and twisted 3 times (+600, -800, +1000T / m) by dry method to produce 240dtex Japanese paper yarn. After piqué knitting, it was washed with water and then dried to produce a knitwear with 10 stitches.

Embodiment 2、 comparative example 2

[0074] [Example 2, Comparative Example 2: Substrate for hydroponics]

[0075] Spread the Japanese paper yarn knitwear prepared in the same manner as in Example 1 on the bottom of a plastic container for hydroponic cultivation, form a mat and moisten it with water, such as Figure 3a Seeds of red mustard greens (left) and romaine lettuce (right) were sown on them and stored at room temperature. 6 days later, if Figure 3b As shown in (left: mustard greens, right: romaine lettuce), good germination was confirmed. Figure 3c It is a photo of red mustard greens harvested 25 days after sowing, Figure 3d It's a picture of romaine lettuce. As Comparative Example 2, the same cultivation was performed using a conventional urethane mat.

[0076]

[0077]Vitamin A contained in the obtained romaine lettuce and the number of common bacteria (viable bacteria number) were analyzed by the methods shown below. The results are shown in Table 3.

[0078] (1) Vitamin A: High Performance ...

Embodiment 3、4、 comparative example 3

[0090] [Example 3, 4, Comparative Example 3: Decontamination Sheet]

[0091] After soaking the Japanese paper yarn knitwear produced in the same manner as in Example 1 for 60 minutes in a liquid obtained by dispersing 5% (w / v) cyanine in 100 L of warm water at 80 to 90°C, It was washed with water, dried naturally outdoors, and colored (Example 4). A 10 cm x 14 cm uncolored Japanese paper yarn knit fabric (Example 3), a Japanese paper yarn knit fabric colored by the above-mentioned method (Example 4), and cotton colored by the same method (Comparative Example 3) were soaked in a mixture containing After a predetermined time in 1000 mL of an aqueous solution of 137Cs, water was collected and radioactivity was measured using a germanium semiconductor detector (manufactured by ORTE, GEM-35). The results are shown in Table 5. In Table 5, "blank sample" is an aqueous solution containing 137Cs.

[0092] [table 5]

[0093]

[0094] As shown in Table 5, although about 25% of 137...

Abstract

The object of the present invention is to provide an agricultural material that is superior in stretchability to paper and exhibits the unique effect of Japanese paper yarn that has not been seen in conventional agricultural materials. The solution of the present invention is an agricultural and horticultural material of a knit or textile comprising Japanese paper yarn.

Description

technical field [0001] The present invention relates to an agricultural and horticultural material, and more specifically, to an agricultural and horticultural material that includes Japanese paper yarns for knitwear or textiles and exhibits the unique effects of Japanese paper yarns in addition to being a biodegradable material . Background technique [0002] Agricultural and horticultural materials are various materials that can be used in agriculture or home gardens, such as multilayer sheets for covering the soil to prevent drying of the soil and suppress the growth of weeds, and mulching for protecting fruits or vegetables from pests Mesh, etc. In recent years, biodegradable materials have been used as agricultural and horticultural materials because they can be hoeed into the soil after harvesting and can reduce the labor and cost of recycling work that was previously necessary. For example, paper multilayer sheets such as kraft paper and Japanese paper are known as ...
