Description

Technical Field

[0001] The utility model relates to the technical field of curtain fabrics, and specifically, to a dimming curtain fabric. Background Art

[0002] The existing dimming curtain fabric includes a first light-transmitting part and a second light-transmitting part, and a plurality of light-shielding parts are adhesively connected between the first light-transmitting part and the second light-transmitting part. When it is necessary to block sunlight, the light-shielding parts stand up, blocking the part between two adjacent light-shielding parts on the first light-transmitting part and the second light-transmitting part, so as to block the sunlight from passing through the first light-transmitting part and the second light-transmitting part. When it is not necessary to block sunlight, the light-shielding parts lie down horizontally, not blocking the part between two adjacent light-shielding parts on the first light-transmitting part and the second light-transmitting part, so that sunlight passes through the first light-transmitting part and the second light-transmitting part.

[0003] As Figure 6 shown, the above technical solution has the following disadvantages: 1. In order to ensure the light-shielding effect, the line density of the light-shielding parts is relatively large, and the softness is poor. When the light-shielding parts stand up or lie down, the deformation of the light-shielding parts and the light-transmitting parts is relatively large, and the appearance is not beautiful; 2. The existing light-shielding parts are of the same hardness and softness. When the light-shielding parts are opened, the fabric forms an S shape. After a long time, fatigue will occur. In addition, the light-shielding parts can only stand up in the forward direction. When the light-shielding parts stand up in the reverse direction, due to the poor softness, the arc at the connection between the light-transmitting part and the first light-transmitting part and the second light-transmitting part is relatively large, and there is a risk of light leakage when blocking light. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a dimming curtain fabric for the above problems, reducing the deformation of the light-shielding parts, making the appearance more beautiful, and reducing the risk of light leakage.

[0005] To achieve the above purpose, the utility model discloses a dimming curtain fabric, which includes a first light-transmitting part and a second light-transmitting part. A first flexible part is connected between one side of the light-shielding part and the first light-transmitting part, and / or a second flexible part is connected between the other side of the light-shielding part and the second light-transmitting part. The light transmittance of the light-shielding part is less than that of the first light-transmitting part and the second light-transmitting part, and the softness of the flexible part is less than that of the light-shielding part. The light-shielding part can be flipped within a range of 180 degrees under the traction of the first light-transmitting part and the second light-transmitting part.

[0006] In this process, due to the relatively soft texture of the flexible part, it is beneficial to bend, facilitating the reduction of the deformation of the light-shielding parts and the light-transmitting parts when the light-shielding parts and the flexible parts stand up or lie down, making the appearance more beautiful; at the same time, fatigue will not occur after a long time, and it is tightly closed when blocking light, and there is no risk of light leakage whether from top to bottom or from bottom to top in high-rise buildings.

[0007] Preferably, the warp density of the light-shielding part is greater than that of the first flexible part and the second flexible part.

[0008] In this structure, since the warp density of the light-shielding part is greater than that of the flexible part, the softness of the flexible part is less than that of the light-shielding part.

[0015] Preferably, the denier of the low melting point yarns is 20D-300D.

[0016] In this structure, the softness of the flexible part is less than that of the light-shielding part.

[0019] Preferably, the total width of the combination of the light-shielding part, the first flexible part and the second flexible part is LS, and the distance between the joints of two adjacent combinations and the first light-transmitting part or the second light-transmitting part is LL, where LL<LS<2LL.

[0020] When it is necessary to block sunlight, in the state where the light-shielding part and the flexible part are fully erected, the light-shielding part can completely block sunlight from passing through the first light-transmitting part and the second light-transmitting part, which is convenient for use.

[0021] Preferably, the first flexible part, the second flexible part are woven and joined with the light-shielding part, the first flexible part is woven and joined with the first light-transmitting part, and the second flexible part is woven and joined with the second light-transmitting part.

[0022] During use, the softness at the woven and joined parts is higher, which is beneficial to bending, and is convenient for reducing the deformation of the light-shielding part when the light-shielding part and the flexible part are erected or laid down, and the appearance is more beautiful.

[0023] Preferably, the first flexible part, the second flexible part are woven and joined with the light-shielding part, the first flexible part is woven and joined with the first light-transmitting part, and the second flexible part is woven and joined with the second light-transmitting part; or, the first flexible part and the second flexible part are separately or integrally arranged, the first flexible part and the second flexible part are adhesively bonded to the light-shielding part, the first flexible part is adhesively bonded to the first light-transmitting part, and the second flexible part is adhesively bonded to the second light-transmitting part.

[0025] Preferably, the first flexible part, the second flexible part or the light-shielding part is made of non-woven fabric, woven fabric or knitted fabric.

[0026] This structure is convenient for processing and manufacturing.

[0027] To sum up, the beneficial effects of the present utility model are as follows: Since the texture of the flexible part is relatively soft, it is beneficial to bend, which is convenient for reducing the deformation of the light-shielding part and the light-transmitting part when the light-shielding part and the flexible part are erected or laid down, and the appearance is more beautiful; at the same time, it will not get fatigued after a long time, and it is tightly closed when blocking light, and there is no risk of light leakage from top to bottom or from bottom to top in high-rise residences.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0041] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners:

[0042] As Figures 1 to 5 shown, a dimming curtain fabric includes a first light-transmitting part 1 and a second light-transmitting part 2. It is characterized in that a first flexible part 401 is connected between one side of the light-shielding part 3 and the first light-transmitting part 1, and / or a second flexible part 402 is connected between the other side of the light-shielding part 3 and the second light-transmitting part 2. The light transmittance of the light-shielding part 3 is less than that of the first light-transmitting part 1 and the second light-transmitting part 2, and the softness of the flexible part is less than that of the light-shielding part 3. The light-shielding part 3 can be flipped within a range of 180 degrees under the traction of the first light-transmitting part 1 and the second light-transmitting part 2.

[0043] Specifically, in one embodiment, a first flexible part 401 is connected between one side of the light-shielding part 3 and the first light-transmitting part 1, and the other side of the light-shielding part 3 is directly connected to the second light-transmitting part 2.

[0044] Specifically, in another embodiment, one side of the light-shielding part 3 is directly connected to the first light-transmitting part 1, and a second flexible part 402 is connected between the other side of the light-shielding part 3 and the second light-transmitting part 2.

[0045] Specifically, in another embodiment, a first flexible part 401 is connected between one side of the light-shielding part 3 and the first light-transmitting part 1, and a second flexible part 402 is connected between the other side of the light-shielding part 3 and the second light-transmitting part 2.

[0046] Specifically, in one embodiment, the light transmittance of the first light-transmitting part 1 is greater than that of the second light-transmitting part 2.

[0047] Specifically, in another embodiment, the light transmittance of the first light-transmitting part 1 is less than that of the second light-transmitting part 2.

[0048] Specifically, in another embodiment, the light transmittance of the first light-transmitting part 1 is equal to that of the second light-transmitting part 2.

[0049] When sunlight needs to be blocked, the light-shielding part 3 and the flexible part stand up, blocking the part between two adjacent light-shielding parts 3 on the first light-transmitting part 1 and the second light-transmitting part 2, thereby blocking sunlight from passing through the first light-transmitting part 1 and the second light-transmitting part 2.

[0050] When sunlight does not need to be blocked, the light-shielding part 3 and the flexible part lie down, not blocking the part between two adjacent light-shielding parts 3 on the first light-transmitting part 1 and the second light-transmitting part 2, so that sunlight can pass through the first light-transmitting part 1 and the second light-transmitting part 2.

[0051] Specifically, the first light-transmitting part 1 can move downward or the second light-transmitting part 2 can move upward, and the light-shielding part 3 and the flexible part rotate clockwise; or the first light-transmitting part 1 can move upward or the second light-transmitting part 2 can move downward, and the light-shielding part 3 and the flexible part rotate counterclockwise. The light-shielding part 3 and the flexible part can rotate 180 degrees, which is more convenient for adjusting the light.

[0052] During this process, due to the relatively soft texture of the flexible part, it is beneficial to bend, which is convenient for reducing the deformation of the light-shielding part 3 and the light-transmitting part when the light-shielding part 3 and the flexible part stand up or lie down, making the appearance more beautiful; at the same time, it will not become fatigued after a long time, and it is tightly closed when blocking light, so there is no risk of light leakage from top to bottom or from bottom to top in high-rise buildings.

[0053] The warp density of the light-shielding part 3 is greater than that of the first flexible part 401 and the second flexible part 402.

[0054] In this structure, since the warp density of the light-shielding part 3 is greater than that of the flexible part, the softness of the flexible part is less than that of the light-shielding part 3.

[0055] The warp threads of the first flexible part 401 or the second flexible part 402 include fine denier multi-F yarns. Specifically, the F number of the yarn is two or more.

[0057] The denier of the fine denier multi-F yarn is 20D - 60D. Specifically, it can be 20D, 30D, 40D, 50D or 60D.

[0058] In this structure, the flexibility of the flexible part is relatively high.

[0059] The warp threads of the light-shielding part 3 include fine denier multi-F yarns and low-melting-point yarns. Specifically, the melting point of the low-melting-point yarn is 100 - 200 degrees Celsius.

[0060] In this structure, since the warp density of the light-shielding part 3 is greater than that of the flexible part, the flexibility of the flexible part is less than that of the light-shielding part 3.

[0061] The denier of the low-melting-point yarn is 20D - 300D. Specifically, it can be 20D, 50D, 100D, 200D or 300D.

[0062] In this structure, the flexibility of the flexible part is less than that of the light-shielding part 3.

[0063] The width of the flexible part is 1mm - 30mm. Specifically, it can be 1mm, 5mm, 10mm, 20mm or 30mm.

[0064] In this structure, it is convenient for the light-shielding part 3 and the flexible part to be bent.

[0065] The total width of the combination of the light-shielding part 3 and the first flexible part 401 and the second flexible part 402 is LS, and the distance between the joints of two adjacent combinations and the first light-transmitting part 1 or the second light-transmitting part 2 is LL, where LL < LS < 2LL.

[0066] When sunlight needs to be blocked, in the state where the light-shielding part 3 and the flexible part are fully erected, the light-shielding part 3 can completely block sunlight from passing through the first light-transmitting part 1 and the second light-transmitting part 2, which is convenient for use.

[0068] During use, the flexibility at the woven joints is higher, which is beneficial for bending, and it is convenient to reduce the deformation of the light-shielding part 3 when the light-shielding part 3 and the flexible part are erected or laid down, making the appearance more beautiful.

[0069] Such as Figure 7As shown, the first flexible part 401 and the second flexible part 402 are separately arranged. The first flexible part 401 and the second flexible part 402 are bonded to the light-shielding part 3. The first flexible part 401 is bonded to the first light-transmitting part 1, and the second flexible part 402 is bonded to the second light-transmitting part 2.

The first flexible part 401 and the second flexible part 402 are bonded to the light-shielding part 3. The first flexible part 401 is bonded to the first light-transmitting part 1, and the second flexible part 402 is bonded to the second light-transmitting part 2.
