Description

  The present invention relates to a horizontal opening / closing curtain.

  It is generally well known that a cold draft occurs around the window glass on a cold winter day, causing inflow of cold air and condensation on the window glass.

  This is because the window glass cooled to the outside air acts as a cooler in the room and cools the air near the window glass, increasing the specific gravity of the air and generating a downdraft, and at that time, saturated water vapor is discharged. This is a phenomenon in which the cycle of condensation on the window glass is repeated.

  As a method for preventing this, the inventor applied for the curtain lower airflow blocking method, the curtain hanging device with a lifting mechanism, and the curtain rail device of Japanese Patent Application No. 2005-173405. With the curtain closed, the curtain rail is lowered to lower the entire curtain, the skirt of the curtain is brought into close contact with the floor, and the flow path of the cold draft descending airflow is blocked, and at the same time, the curtain is the boundary. Then, an air insulation layer is formed on the window side to improve the room temperature insulation.

  This is an improvement over the drawbacks of the conventional method of making the curtain length longer in winter and keeping the curtain hem in close contact with the floor. That is, according to the above-described method, the skirt is always dragged when the curtain is opened and closed, so that the movement of the curtain is disturbed. It eliminates the disadvantages of detracting from aesthetics, such as the curtain hem being easily soiled and frayed.

  According to the above-described method of eliminating the gap between the top, bottom, left and right of the curtain, the inflow of cold air is remarkably reduced and the discomfort caused by the cold air is eliminated. Proven.

  However, at this time, it was confirmed that the harmful effect of increasing the amount of condensation on the window glass occurred. This is because the flow of air can be prevented in conventional curtains, but the moisture contained in the air cannot be prevented from moving, so the saturated water vapor contained in the air is increased by the increase in room temperature and comfort. The amount increases, and as a result, the amount of condensation on the window glass increases accordingly.

In other words, it is considered that such a problem occurs because most of the conventional curtain fabric is made of moisture-permeable fabric.
Some of the conventional curtains for indoor use have a water-repellent finish, but the aim was mainly to prevent soiling of the fabric and to prevent shrinkage due to moisture, and it was in the category of moisture-permeable waterproofing. There are no products that prevent the condensation of curtains due to the moisture-impermeable function as described above.

  For shower curtains, fabrics such as nylon that have water repellency and waterproof functions are common, but they do not satisfy the texture, texture, volume, etc. required for indoor curtains. It is desired to develop a curtain with impermeable properties without impairing the functions of the fabric such as texture, pattern, design, fashion, heat retention, heat insulation, light shielding, and soundproofing.

The present invention provides a curtain to which moisture impermeability is added for a popular indoor curtain excluding a shower curtain.
It is intended to provide curtains with moisture impermeability without impairing functions such as fabric texture, pattern, design, fashionability, heat retention, heat insulation, light shielding, soundproofing, etc. is there. In addition, this moisture-impermeable curtain is used to provide a method for preventing moisture from moving from the indoor side to the window side while the curtain is closed, thereby preventing window condensation.

The main configuration of the present invention is as follows.
(1) A method of preventing condensation of the window by making it difficult for moisture to move from the indoor side to the window side when the curtain is closed by using a moisture-impermeable and waterproof curtain.
(2) By using a curtain with a moisture permeability of 2000 g / m2-24h or less, which prevents moisture from moving from the indoor side to the window side when the curtain is closed, that is, with the curtain closed. How to prevent window condensation.
(3) Curtain with impermeable and waterproof treatment.
(4) A curtain that has been subjected to moisture-impervious waterproofing with a moisture permeability of 2000 g / m 2-24 h or less.
(5) Indoor curtains that have flexibility as seen in laminates and coatings such as rubber, fluororesin, vinyl, nylon, urethane, silicone, vinyl chloride resin, chlorosulfonated polyethylene resin, and water repellent Teflon. A highly waterproof material with a moisture permeability of 2000 g / m2-24h or less by spraying, applying, printing, sticking, sewing, laminating, coating, etc. with a waterproof material in sheet form on one or both sides of the curtain A curtain and a curtain fabric characterized in that a film is formed and a moisture-impermeable function is added to the curtain.
(6) Indoor curtains with a moisture permeability of 2000 g / m2-24h or less, such as rubber, fluororesin, vinyl, nylon, urethane, silicon, vinyl chloride resin, chlorosulfonated polyethylene resin, water repellent Teflon A curtain having a moisture-impermeable function added to the curtain by adhering a sheet having a moisture-impermeable waterproof function to the curtain, and forming a moisture-impermeable film by adhering by a method such as sewing, pressure bonding, and heat fitting. Curtain fabric.
(7) By using the curtains of (3), (4), (5), and (6) above, it is difficult for moisture to move from the indoor side to the window side with the curtain closed, and condensation of the windows is prevented. How to prevent.

  According to the curtain of the present invention, if there is no gap between the top, bottom, left and right of the curtain when the curtain is closed, the movement of air and moisture between the window side and the indoor side can be blocked by the curtain, so that the room temperature insulation is maintained. This improves energy efficiency and reduces discomfort due to the inflow of cold air. In addition, since moisture transfer is reduced, it can be expected to reduce the amount of condensation on the window glass.

The present invention does not impair the moisture permeability which has been a drawback without impairing the fabric pattern, texture, design, fashionability, heat retention, heat insulation, light shielding, soundproofing and other functions of conventional curtain fabrics. It is something to try.
It is characterized in that a conventional curtain fabric is arranged on the indoor side as a surface and a sheet-like waterproof film is provided on the lining or intermediate layer.
Conventionally, some water-repellent curtain fabrics, which have been seen in some cases, have been woven with waterproof fibers, or sprayed or coated with a waterproofing agent such as fluororesin on the fabric. Moisture passed through the gaps between the fibers and between the adhering spray particles. That is, since the water-repellent layer is mesh-like or patchy, the moisture-repellent waterproofing process is insufficient to block the movement of moisture.
On the other hand, the present invention is characterized in that the movement of moisture can be completely blocked by providing a sheet-like waterproof film. There are some waterproof membrane construction methods that are very similar to conventional methods, such as attaching and sewing an independent waterproof membrane to the back of the outer material, or printing and applying a waterproofing agent directly to the rear surface of the outer material. Thick enough to fill the gap, it is completely different from the conventional one in that it is aimed at moisture impervious waterproofing.
