[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD This invention relates to an improvement in a light-shielding curtain suitable for use in indoor applications that require flame retardancy, such as theater interiors. Prior Art and Problems Conventionally, blackout curtains used in public places such as theaters have been required to be flame retardant, and the design of blackout curtains suitable for use in such places has been The surface layer in the cross-sectional structure (assuming that the curtain is attached so that the surface layer faces indoors) is a fiber-based fabric (however, this fabric is a broad term that refers to curtain fabric, and is in fact a knitted fabric). It is known that a resin layer constituting artificial leather is bonded to the synthetic leather. For example, Utsukai Showa 61-15878. In manufacturing curtains with the above structure, it is easy to make the resin layer flame retardant, but pre-flame retardation of the curtain fabric fibers (for example, by kneading flame retardant into the base material) is expensive. Therefore, it is common practice to treat non-flame retardant fabrics to make them flame retardant. The present invention relates to improving the flame retardancy of fiber/resin bonded type blackout curtains produced by this fabric post-treatment method. In other words, when the above types of flame-retardant blackout curtains are washed, they lose their flame-retardant properties. When you receive it,
The flame retardant performance deteriorated, and it had the drawback of failing to pass the Fire and Disaster Management Agency's (A) label. The present invention ameliorates this drawback. Means for Solving Problems and Effects That is, the present invention provides flame-retardant and wash-resistant curtain fabric by further applying water-repellent or oil-repellent treatment using a futsuo-based compound or silicon-based compound to curtain fabric that has been subjected to flame-retardant treatment. Improvements have been made to improve the properties of the material, allowing it to pass the above flame retardant (A) label even after repeated dry cleaning and washing with water, and at the same time improve wrinkle resistance, stain resistance, etc. be. Examples will be described below, including selection of curtain fabric (surface layer) and curtain configuration. The curtain fabric (surface layer) may be selected from polyester, polyacrylic, nylon, polypropylene, rayon, natural fibers, etc., but if the weave structure is relatively fine, as shown in Figure 1, the surface layer Layer 1/dark color (for example, black) light-shielding adhesive resin layer 2/any colored leather back layer 3 can be suitably constructed, and the resins used for these 2 and 3 are polyurethane, nylon, polyethylene, etc. , polyacrylic esters, and the like. When the surface layer of the fabric has a relatively coarse weave structure, as shown in FIG. 2, the surface layer 1/transparent or light-colored adhesive resin layer 2a/
A structure of a dark-colored (for example, black) light-shielding coating layer 4/any colored coating back layer 3 can be suitably taken, and the resins used in the above-mentioned 2a and 4 can be similarly selected from the above-mentioned ones. The production of the above-mentioned light-shielding curtains will be described as follows: A. The curtain fabric is subjected to flame retardant treatment using, for example, an aliphatic cyclic phosphonic acid ester-based drug, and B. Then, the surface layer of the curtain fabric is bonded. A doctor knife is used to sequentially remove the resin that forms the adhesive resin layer and the film layer.
A method of completing multiple layers by coating with a reverse roll coater, roll-on knife coater, etc. C Alternatively, a transfer method may be used in which a colored layer, a light-shielding layer, or an adhesive layer are sequentially provided on a release paper, a surface layer is laminated, and the release paper is peeled off after aging. D Alternatively, it is also possible to provide only an adhesive layer on the surface layer, and then provide a light-shielding layer and a colored layer thereon by a calendering method, an extrusion method, or the like. E The amount of solid content applied above is usually 10 to 150 g/m ² for the colored layer, light shielding layer, and adhesive layer. F Among methods B, C, and D above, the texture of the product,
Method C is preferable due to its softness, ease of processing, lightness, etc. G Water- and oil-repellent treatment using a fluorine-based compound or a silicone-based compound may be applied to the surface layer fabric before it is bonded to other layers as described above, or it may be applied to the surface layer fabric before it is bonded to other layers. This may be done after the fabric has been joined with other layers. The fluoroalkyl group-containing compound described as a fuso-based compound is used as an aqueous dispersion or an organic solvent solution. The compounds may be used alone or in a mixture. Furthermore, a silicone compound and a reactive resin having a methylol group can also be used in combination with the fuso compound. and for the textile products to be processed.
Treat by absorption method, coating method, etc. so that 0.1 to 10% by weight adheres. As the silicone-based compound, one containing organohydrodiene polysiloxane as the main ingredient and a curing catalyst blended therein is suitable. For example, an organic halogen-based polyvalent metal oxide can be used to make the resin layer flame retardant. Examples and Comparative Examples The curtain fabric that is the surface layer is commonly used, and its surface color may be either undyed or appropriately dyed. Generally, the basis weight of curtain fabric is 50 to 50.
250 g/m ² is preferred. Below, the curtain fabric is polyester filament 100 denier/72 filament in warp and weft, warp density 176.8x2, weft density 303, basis weight.
A material woven at 99.13 g/m ² was used. The above fabric was previously flame-retardant treated with an aliphatic cyclic phosphonic acid ester, and then a water- and oil-repellent 1% solution of solids was applied to the fabric using a gravure roll coater (120 wires). Apply with roll)
Dry at 120 ^0e for 1 minute, solid content coverage 0.1 to 0.29/m ²
A treatment layer was provided. A colored back layer (corresponding to 3 in Figure 2 above) of a resin compound liquid is applied onto a polypropylene release paper.
Dry at 100 ^0C for 1 minute to form a back layer with a solid content of 40g/m ² , then apply a resin blend solution for the light shielding layer (corresponding to 4 in Figure 2 above) and dry at 100 ^0C for 1 minute. A light-shielding layer with a solid content of 35 g/m ² was formed, and an adhesive (corresponding to 2a in Fig. 2 above) was applied.
After drying at 80 ^°C for 1 minute to form an adhesive layer with a solid content of 40g/m ² , it was immediately bonded to the curtain fabric that had been treated with the above-mentioned water- and oil-repellent treatment and was left at room temperature for 24 hours.
Time aged. Thereafter, the release paper was peeled off to produce light-shielding curtains of Example A and Comparative Example B. The table shows the resin formulations employed in the production of Example A and Comparative Example B and the flame retardant test results of the curtains.
