[Industrial applications]

 The present invention relates to a UV-cut blind which prevents skin aging and sunburn due to UV rays by using a sheet material having extremely high UV absorption and shielding properties.

[0002]

[Prior art]

 Generally, ultraviolet rays are classified into three types, UV-A (320 to 400 nm), UV-B (290 to 320 nm), and UV-C (280 nm or less), depending on the length of the wavelength. It is absorbed and scattered and does not reach the surface of the earth. UV-A has a long wave length and reaches the dermis, and if it is exposed to this everyday, the elasticity and tension of the skin are lost, and melanocytes (pigment forming cells) are activated to darken spots and freckles. Promote aging. This UV-A also penetrates the window glass and adversely affects the skin in daily life. On the other hand, UV-B causes ultraviolet rays having a short wavelength to cause inflammation of the epidermis, which is a main cause of outdoor sunburn particularly by sea bathing, skiing, golfing and the like.

These ultraviolet rays easily cause photocontact dermatitis. The types of dermatitis are phototoxicity, which is activated by ultraviolet rays when they are in contact with the skin and stimulates the skin to cause inflammation. There is photoallergy caused by the production of antigens. Photocatalytic dermatitis is easier and more effective to prevent UV radiation through blinds than to prevent it by applying sunscreen cosmetics to the skin.

[0004]

[Problems to be solved by the device]

 Woven fabrics such as cotton, polyester and cotton, acrylic and cotton, and lace products already exist as UV-cut fabrics for preventing photo-contact dermatitis due to ultraviolet rays. It is true that the aging of skin and sunburn due to ultraviolet rays in the sun's rays can be prevented to some extent by sewing car shades, sun shade handle covers, sun shade drive gloves, etc. with these fabrics.

However, this type of UV-cut fabric is not very good in ultraviolet absorption and shielding properties, and has poor moisture absorption and release properties in the rainy season with high humidity, resulting in poor usability in the room. In addition, these cloth products have low cushioning property and rigidity, and the places where they can be suitably used are naturally limited.

The present invention has been proposed in order to improve the above-mentioned problems associated with conventional UV-cut fabrics, and has excellent UV absorption and shielding properties, as well as high UV absorption and release properties. It is intended to provide blinds for cuts. Another object of the present invention is to provide a UV-cut blind which can be applied to a special purpose by improving characteristics such as cushioning property or rigidity.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the corrugated sheet material 5 (Fig. 2) for the blind 1 (Fig. 5) of the present invention is a sheet material mainly made of wool felt, or a fiber wrap. Use a sheet material that has been integrated into a sheet and then coated with a keratin additive or UV cut chemical. Examples of the UV-cutting agent include polyurethane resin in which fine particles of anhydrous silica are emulsified and dispersed. Generally, the thickness of this sheet material is set to about 0.5 to 1.0 mm and its density is set to 0.20 to 0.50.

The sheet material may be manufactured by, for example, slicing an appropriately entangled wool felt into a sheet shape, or by pressing the felt. As illustrated in FIG. 1, the sheet material 2 may be formed by integrating a fiber wrap 3 such as wool with a thin reinforcing cloth 4 such as woven or knitted cloth into a sheet by needle punching or water jet processing. . The needle punching or the water jet treatment may be performed not only individually, but also after the needle punching is integrated into a sheet shape, the water jet treatment may be further performed once or several times.

This sheet material is impregnated with a thermoformable resin, and is then molded into a corrugated cross-section by heating and pressurizing using a publicly known press or molding machine. ) Get. The moldable resin with which the sheet material is impregnated is, for example, acrylic resin, polyvinyl chloride resin, SBR resin, or the like.

As shown in FIG. 3, a bar 7 made of metal or plastic can be preliminarily inserted into each bent portion 6 of the corrugated sheet material 5 for easy folding or reinforcement. . The corrugated sheet material 5 is trimmed around the corrugated sheet material 5 as desired, or a wire or the like is sewn into the perimeter or the inside of the corrugated sheet material 5 to enhance the shape retention, thereby forming the blind 1.

[0011]

[Action]

 Since the blind 1 of the present invention mainly uses the wool-made felt or the keratin additive or the sheet material 2 coated with the ultraviolet ray-cutting agent, the ultraviolet ray-absorbing property and the shielding property are very high. The blind 1 almost completely blocks strong sunlight, and has a high moisture absorbing / releasing property in the rainy season, which makes the indoor feeling good.

The blind 1 of the present invention is formed by impregnating a thermoformable resin and molding it by heating and pressurizing, thereby maintaining a predetermined corrugated cross-sectional shape and having a special use which is not present in conventional metal blinds. Applicable to If desired, the blind 1 may be subjected to a water jet treatment from above to promote close entanglement of the fibers to remove short fibers that cause fluff from the sheet material 2.
