Abstract

Disclosed is a protective bag that is formed by depositing a light-reflective material and a photocatalyst material on the outer surface of an air-permeable bag. It is preferable that: indentations are formed on the outer surface of the air-permeable bag, and the light reflective material is a coloured fibre and contains first light-reflective particles having a volume average particle size of 100[mu]m-200[mu]m and second light-reflective particles having a volume average particle size of 1[mu]m-5[mu]m.

Description

technical field

[0001] The invention relates to a protective bag for protecting agricultural products such as fruits from pests and the like. Background technique

[0002] Ethylene gas, a growth-promoting substance, generated from agricultural products such as fruits is known to have an effect of promoting the ripening of the above-mentioned agricultural products. In particular, it has been reported that ethylene gas generated from apples causes fruit drop from branches. .

[0003] In addition, the above-mentioned agricultural products generate ethylene gas even after harvesting, and in a space where the concentration of ethylene gas is high, the ripening of the above-mentioned agricultural products is significantly accelerated to cause spoilage.

[0004] Therefore, it is necessary to remove ethylene gas in order to prevent the aforementioned agricultural products from falling and also maintain freshness after harvesting.

[0005] Conventionally, there has been a method of...

Examples

Embodiment 1

[0221] (Example 1: Carrying photocatalyst titanium apatite, coated with light reflective material, the shape of the protective bag is spherical, the structure of the protective bag is formed without recesses on the surface, and the material of the protective bag is non-woven fabric)

[0222]

[0223] A spherical air-permeable bag with a diameter of 300 mm (trade name "fruit bag", manufactured by Sato Sesaku) made of nonwoven fabric (material: pulp, PE, etc.) was prepared. The air-permeable bag was immersed in the aqueous dispersion of photocatalyst titanium apatite prepared as follows for 10 seconds, and dried at 120° C. for 3 hours to make it support the photocatalyst titanium apatite. The prepared aqueous dispersion of the light reflective material was sprayed and dried at 120° C. for 3 hours, and then coated with the light reflective material on the outer surface.

Embodiment 2

[0274] (Example 2: the shape of the protective bag is cube-shaped)

[0275] Except that by using the spherical gas permeable bag of Example 1 and the same surface area as a cube-shaped gas permeable bag with a length of 100 mm to make a protective bag, the same operation was carried out as in Example 1, and the production and evaluation of the protective bag were carried out ( Measurement of photocatalyst titanium apatite loading capacity of protective bag, measurement of coating amount of light reflective material of protective bag, measurement of light reflectance of protective bag, measurement of ethylene gas permeability of protective bag, ethylene gas adsorption of protective bag or degradation performance), cultivation experiments (measurement of ethylene gas concentration, fruit drop rate, bird damage rate, mold rate), storage experiments (ethylene gas concentration, spoilage rate) , Determination of decay rate on the bottom side, measurement of heat retention effect). ...

Embodiment 3

[0276] (Example 3: The shape of the protective bag is a bellows (level difference) type shape)

[0277] Except that by using 100 parallel gas-permeable spherical bags with a width of 10 mm and a height of 0.5 mm to make a protective bag, the protective bag was prepared in the same manner as in Example 1. and evaluation (measurement of the photocatalyst titanium apatite loading capacity of the protective bag, measurement of the coating amount of the light reflective material of the protective bag, measurement of the light reflectance of the protective bag, measurement of the ethylene gas permeability of the protective bag, the measurement of the protective bag Measurement of ethylene gas adsorption or degradation performance), cultivation experiments (measurement of ethylene gas concentration, measurement of fruit drop rate, measurement of damage rate caused by birds, measurement of moldy rate), storage experiments (measurement of ethylene gas concentration, decay Determination...
