Problems solved by technology

[0004] However, this kind of light-shielding curtain cloth woven with composite yarns will cause environmental problems because it contains PVC that is not easy to corrode.
Furthermore, because PVC is not easy to shape after being bent, it is not suitable for making curtains with multiple pleats such as Roman shades, otherwise there will be uneven lack of pleats concentrated at the lower end of the curtain due to gravity
In addition, because the curtain fabric with light transmittance is made by weaving method, fringe is easy to appear on the edge, which damages the sense of value of the finished product

Embodiment Construction

[0022] The foregoing and other technical contents, features and functions of the present invention will be clearly understood in the following detailed description of preferred embodiments with reference to the accompanying drawings.

[0023] As shown in FIG. 1 , the present invention is used to manufacture the equipment 1 of the light-shielding sheet material with predetermined light transmittance, comprises the greige cloth 11 that rolls is guided by a plurality of rollers 12, passes through the impregnation tank 14 that paint 13 is housed in sequence, a Pressing roller 15, drying and shaping zone 16 (blowing device 161, dryer 162), and cooling zone 17 (cooling wheel 171), finally the shading sheet 18 is rolled into a cylinder for storage or transportation.

[0024] According to the operation sequence of the equipment shown in Figure 1, the manufacturing method of the light-shielding sheet 18 with predetermined light transmittance of the present invention comprises: providing...

Abstract

A lightproof sheet material with a predetermined transmittance and the manufacturing method thereof are provided. The method comprises the following steps: providing a knitted substrate with a plurality of holes, immersing the substrate in a coating, extruding the substrate adhered with the coating, blowing off the coating in the plurality of holes to allow the substrate to have the plurality of holes, and drying and shaping. The lightproof sheet material has a plurality of holes and thus has a predetermined transmittance.

Description

technical field [0001] The invention relates to a shading sheet with predetermined light transmittance and its manufacturing method, in particular to a shading sheet used as a curtain cloth and its manufacturing method. Background technique [0002] Curtain fabrics are divided into two categories: opaque curtain fabrics and curtain fabrics with predetermined light transmittance. An existing light-tight curtain cloth is to apply a high-concentration and high-viscosity mixture such as resin, titanium dioxide (TiO2), and coloring material on the opposite sides of the cloth for multiple times with a scraper, and the The gap is completely filled and made. The disadvantage of this kind of opaque curtain fabric is that it almost completely loses the texture of the fabric; and because the coating is too thick, it will crack when the curtain fabric is folded and cannot maintain the shape of the pleats for a long time; Gravity makes the pleats closer to the upper end of the curtain ...
