Heat insulation sheet for tent

Abstract

Provided is a heat insulation sheet for a tent that suppresses the temperature rise inside the tent on sunny days. 【Solution means】A heat insulation sheet S for a tent, in which a water repellent layer 2 is formed on the surface of a base fabric 1 in which warp and weft are nylon yarns and aluminum raw yarns are woven in one direction, and a polyurethane processing layer 3 is formed on the back surface.

Description

Technical Field

[0001] The present invention relates to a heat insulation sheet for a tent that prevents the temperature inside the tent from rising due to strong sunlight, the irregular reflection of light and heat, and the irregular reflection of light and heat due to radiation, and improves the living environment.

Background Art

[0002] Conventionally, outdoor tents have mainly been used as sunshades on sunny days. However, even when direct sunlight is avoided on sunny days, it has been difficult to withstand the rise in temperature inside the tent.

[0003] Therefore, the applicant of the present application proposed a heat insulation sheet for a tent in which a Teflon processing layer is formed on the surface of a base fabric woven with aluminum raw yarn as the warp and nylon yarn as the weft, and a black polyurethane processing layer is formed on the back surface (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] With the above proposal, the heat insulation and light shielding effects were demonstrated, and the effects of preventing the temperature inside the tent from rising due to strong sunlight, the irregular reflection of light and heat, and the irregular reflection of light and heat due to radiation could be obtained.

[0006] However, the aluminum raw yarn has weak tear and tensile strength, and there is a risk of insufficient strength such as wind countermeasures with only one-way nylon yarn. The purpose of the present invention is to provide a heat insulation sheet for a tent that improves strength and improves the living environment.

Means for Solving the Problems

[0007] In order to solve the above problems, the heat insulation sheet for tents of the present invention is characterized in that the warp and weft are nylon (registered trademark) threads, a water-repellent layer is formed on the surface of a base fabric in which aluminum raw yarns are woven in one direction, and a polyurethane-treated layer is formed on the back surface (Claim 1). Note that the disclosure of the warp, weft, and one direction thereof is a relative expression and does not have a specific meaning respectively.

[0008] According to the heat insulation sheet for tents of the present invention having the above configuration, since both the warp and weft are made of nylon threads, the strength of the base fabric containing aluminum raw yarns is improved, and the surface has heat insulation, heat insulation, light shielding, ultraviolet shielding, and antifouling effects due to the functions of the base fabric and the water-repellent layer.

[0009] Furthermore, the polyurethane-treated layer on the back surface prevents irregular reflection of light and heat, prevents irregular reflection of light and heat due to radiation, and reduces glare and the like. As a result, the heat insulation sheet of the present invention suppresses the rise in temperature inside the tent by the functions of the base fabric and both the front and back surfaces, and improves the living environment.

[0010] One embodiment of the present invention is characterized in that the polyurethane-treated layer on the back surface is black (Claim 2). According to this embodiment, irregular reflection of light and heat due to radiation is prevented, and glare inside the tent is reduced.

[0011] One embodiment of the present invention is characterized in that the polyurethane-treated layer on the back surface contains a flame retardant (Claim 3). According to this embodiment, the flame retardant improves the flame retardant effect of the entire sheet.

Effects of the Invention

[0012] According to the present invention, it is possible to provide a heat insulation sheet for tents that improves strength, prevents the temperature inside the tent from rising due to strong sunlight and irregular reflection of light and heat, and further prevents irregular reflection of light and heat due to radiant heat.

Embodiment for Carrying out the Invention

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] The heat insulation sheet S for a tent of the present invention is composed of a base fabric 1 in which warp and weft are nylon threads and aluminum raw threads are woven in one direction. Here, warp and weft are relative expressions, and one direction means either warp or weft.

[0016] In the present invention, a water-repellent layer 2 is formed on the surface of the base fabric 1 that directly receives sunlight (hereinafter referred to as the "surface"). For example, Teflon (registered trademark) treatment is performed.

[0017] Furthermore, a polyurethane processing layer 3 is formed on the inner surface of the tent of the base fabric 1 (hereinafter referred to as the "back surface"). Preferably, the polyurethane processing layer 3 is formed in black.

[0018] The formation of the water-repellent layer 2 and the polyurethane processing layer 3 can be performed by adding coating agents to Teflon (registered trademark) and polyurethane, adjusting the thickness according to the usage, coating them on the base fabric 1 respectively, and then integrating them with the base fabric 1 by heat treatment.

[0019] Furthermore, in the present invention, the polyurethane processing layer 3 on the back surface is preferably a layer containing a flame retardant. As the flame retardant, flame retardant antimony is preferable.

[0020] The heat insulation sheet for a tent having the above configuration has strength against wind countermeasures and the like, and its surface is a silver-white surface. Therefore, it exhibits heat insulation, heat insulation, light shielding, and ultraviolet shielding properties, and has antifouling properties due to the water-repellent layer.

[0021] On one side, the inner surface prevents the irregular reflection of light and heat and exhibits the effect of preventing such irregular reflection of light and heat. Therefore, due to the functions of both the front and back surfaces of the heat-insulating sheet for tents of the present invention, the temperature rise inside the tent is suppressed to maintain a good living environment.
