FIG. 1 is a perspective schematic diagram of a dimming and heat-insulating curtain cloth 100 according to some embodiments of the present disclosure. Fig. 2 is a schematic front view of the dimming and heat-insulating curtain cloth 100 of Fig. 1, and Fig. 2 is a state in which the dimming and heat-insulating curtain cloth 100 is unfolded on its entire surface. Please refer to Figure 1 and Figure 2 at the same time. The dimming and heat-insulating curtain cloth 100 includes a light-transmitting area TA and a light-shielding area SA. In some embodiments, the light-transmitting area TA and the light-shielding area SA may be alternately arranged, for example. More specifically, the dimming and heat-insulating curtain cloth 100 may be, for example, a zebra curtain. The dimming and heat-insulating curtain cloth 100 of the present disclosure can be rolled by a lifting device so that the shading area TA selectively shields part or the entire light-transmitting area SA (as shown in Figure 1), so as to adjust the adjustment according to the needs of indoor personnel. Light penetration and heat insulation of the light-insulating curtain cloth 100.

The light-transmitting area TA and the light-shielding area SA of the dimming and heat-insulating curtain cloth 100 of the present disclosure are each alternately woven by warp yarn 102 and weft yarn 104, and warp yarn 102 is polyester with a yarn diameter between 0.10 mm and 0.15 mm. Single yarn. By using polyester single yarns within the above yarn diameter range as the warp yarns 102 in the light-transmitting area TA and the light-shielding area SA, the weaving density of the weft yarn 104 in the light-transmitting area TA and the light-shielding area SA can be well controlled.

TA has better shading and heat insulation properties. In some embodiments, the knitting density of the weft yarn 104 in the light-shielding area SA may be between 54 yarns/inch and 100 yarns/inch, and the knitting density of the weft yarn 104 in the light-transmitting area TA may be 24 yarns/inch. To 28 pieces/inch. Due to the difference in the weaving density of the weft yarn 104, the light-shielding area SA of the dimming and heat-insulating curtain cloth 100 can have good light-shielding and heat insulation effects, and the light-transmitting area TA can have good light penetration. In this way, the dimming and heat-insulating curtain cloth 100 can have good light regulation and heat insulation performance by staggering or overlapping the shading area SA and the light-transmitting area TA.

The width W1 of the light-shielding area SA of the dimming and heat-insulating curtain cloth 100 of the present disclosure is greater than the width W2 of the light-transmitting area TA to ensure that the light-shielding area SA can completely shield the light-transmitting area TA, thereby avoiding light from the external environment under specific requirements Enter the indoor environment. In some embodiments, the width W1 of the light-shielding area SA is 115% to 125% of the width W2 of the light-transmitting area TA, so that the light-shielding area SA can well shield the light-transmitting area TA when the light is to be shielded, and prevent the light-shielding area SA from being exposed to light. The light-transmitting area TA is still blocked when the light is to be transmitted.

Fig. 3 shows a schematic cross-sectional view of the dimming and heat-insulating curtain cloth 100 of Fig. 2 taken along the line AA′. Please refer to Figure 3. The thickness T1 of the shading area SA of the dimming and heat-insulating curtain cloth 100 of the present disclosure is greater than the thickness T2 of the light-transmitting area TA, so that the shading area SA can have good shading and heat insulation performance, and the light-transmitting area TA can have good Light penetration. In this way, the dimming and heat-insulating curtain cloth 100 can have good light regulation and heat insulation performance by staggering or overlapping the shading area SA and the light-transmitting area TA. In some embodiments, the thickness T1 of the light shielding area SA may be between 0.54 mm and 0.56 mm, and the thickness T2 of the light transmission area TA may be between 0.34 mm and 0.38 mm.
