Description

Technical Field

[0001] The present application relates to the technical field of curtain fabrics, and in particular to a laminated composite curtain fabric. Background Art

[0002] Curtain fabrics, as a kind of home decoration fabrics, are of various types in modern times. With the improvement of production level, people have more and more requirements for curtain fabrics, but the functionality of existing curtain fabrics is relatively single. How to prepare a multifunctional curtain fabric through multi-layer composite has become a problem to be solved.

[0003] Curtain fabric is a curtain made of decorative fabric through design and sewing. It has the functions of sunshade, heat insulation and indoor light adjustment. Families often use a layer of window screen and a layer of curtain. The curtain track includes a curtain rail and a curtain rod. The curtain rail is generally installed in the curtain box. The curtain rod itself is a decoration and can be used for open installation. With the continuous improvement of people's material quality of life, the pursuit of high-quality home life is getting higher and higher, which is reflected in the increasingly high aesthetic and functional requirements on curtains. Curtain fabric will inevitably produce a lot of dust when used. Most of the curtain fabrics in the prior art are completely made of fabric. Especially in the dry environment of autumn and winter, curtain fabrics are prone to static electricity and cause a lot of dust to be adsorbed on the surface of the curtain. When dust accumulates on the curtain fabric, it is very difficult to clean this part of the dust. Users often need to remove the entire curtain and wash it to keep the curtain fabric clean, which is very troublesome.

[0004] The main function of curtains is to isolate the room from the outside light source and maintain the privacy of the room. At the same time, it is one of the indispensable decorations for home decoration. Modern curtains can reduce light and block light to meet people's needs for different light intensities; they can also prevent wind, moisture, mildew, dust, radiation, and ultraviolet rays to improve the climate and environment of the room. Therefore, the ingenious combination of decoration and practicality is the biggest feature of modern curtains.

[0005] Therefore, we proposed a functional laminated composite curtain fabric to solve at least one of the above technical problems. Summary of the invention

[0006] The purpose of this application is to provide a laminated composite curtain fabric, in which a white elastic laminated layer and a silver elastic laminated layer are directly bonded to a black base fabric layer, thereby eliminating the need for dipping adhesive and simplifying the structure of the composite curtain fabric. At the same time, a back-coated silver laminated layer is provided to reduce the light transmittance. Both the white elastic laminated layer and the silver elastic laminated layer are modified for flexibility and antibacterial and mildew resistance. The black base fabric layer is light and environmentally friendly, has good light-shielding properties, strong weather resistance, strong mechanical properties, good antibacterial and mildew resistance, and a long service life. The edges of the laminated composite curtain fabric are subjected to high-frequency embossing treatment, which increases the tensile strength and bending resistance, and has a wider range of applications.

[0007] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted in this application is: a laminated composite curtain fabric, characterized in that it includes:

[0008] A black base fabric layer, wherein at least a white elastic coating layer is arranged on the front side of the black base fabric layer, and the gram weight of the black base fabric layer is 80-180 g / m 2 ;

[0009] A silver elastic coating layer with antistatic capability is bonded to the back of the black base fabric layer.

[0010] As a preferred technical solution, the coating weight of the white elastic coating layer is 70-120 g / m 2 .

[0011] As a preferred technical solution, the weight of the silver elastic coating layer is 60-90 g / m 2 .

[0012] As a preferred technical solution, the surface of the white elastic coating layer is non-smooth textured.

[0013] As a preferred technical solution, the non-smooth texture is one of fine velvet, coarse velvet, frosted, flash point, diamond silk surface, honeycomb type, and leather texture.

[0014] As a preferred technical solution, the surface of the silver elastic coating layer is frosted.

[0015] As a preferred technical solution, the weight of the black base fabric layer is 80-180 g / m 2 .

[0016] As a preferred technical solution, the weight of the laminated composite curtain fabric is 240-360 g / m 2 .

[0017] As a preferred technical solution, the material of the black base fabric layer is at least one of polyester, polypropylene, nylon, spandex, acrylic, ultra-high molecular weight polyethylene fiber, and glass fiber.

[0018] The beneficial effects of this application are:

[0019] 1) The elastic coating layer is directly bonded to the black base fabric layer, which can save the dipping adhesive and simplify the composite curtain fabric structure and production process. The non-use of adhesive also reduces the solvent pollution to the indoor environment. At the same time, a silver coating layer is set to reduce the light transmittance. The elastic coating layers on both sides are modified for flexibility and antibacterial and mildew resistance. The black base fabric layer is light and environmentally friendly, has good light-shielding properties, strong weather resistance, strong mechanical properties, good antibacterial and mildew resistance, and a long service life. The edges of the coated composite curtain fabric are high-frequency embossed to increase the tensile strength and bending resistance, and have a wider range of applications.

[0020] 2) The weight of the white elastic coating layer is reasonable. It is not too thick to affect the winding or bending of the composite curtain fabric, nor is it too thin to affect the covering effect.

[0021] 3) The weight of the silver elastic coating layer is reasonable, not too thin to cause poor shading effect, and not too thick to increase the cost.

[0022] 4) The white elastic coating layer faces the outdoors directly and can reflect sunlight. Making it into a non-smooth texture is conducive to diffuse reflection and prevents the reflected sunlight from being too glaring.

[0023] 5) Thermoplastic elastomer materials are added to the front and back elastic coating layers for modification, which improves the flexibility and low temperature resistance of the composite curtain fabric. Antibacterial masterbatch is added to the front and back elastic coating layers to improve the antibacterial and mildew resistance, so that the coated composite curtain fabric can be used in high-humidity environments such as bathrooms.

[0024] 6) The weight of the black base fabric layer has a great influence on the performance of the laminated composite curtain fabric. If the black base fabric layer is too thin, it will affect the tensile strength, light-shielding and other physical properties of the laminated composite curtain fabric. If it is too thick, it will limit the flexibility and application range of the laminated composite curtain fabric.

[0025] 7) By setting up a black base fabric layer and a silver elastic coating layer with silver powder masterbatch added, a double-layer shading effect can be achieved to improve the shading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described below in conjunction with the accompanying drawings.

[0030] The same or similar numbers in the drawings of the embodiments of the present application correspond to the same or similar parts; in the description of the present application, it should be understood that if the terms "head", "tail", "top", "bottom", "left", "right", "front", "back", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0031] See also Figure 1-Figure 2 One embodiment of the present application provides a laminated composite curtain fabric, comprising a black base fabric layer 2, wherein at least a white elastic laminated film layer 1 is bonded to the front of the black base fabric layer 2, and the gram weight of the black base fabric layer 2 is 80 to 180 g / m 2 , a silver elastic coating layer 3 bonded to the back of the black base fabric layer 2.

[0032] The existing black base fabric layer 2 needs to be coated with adhesive, and then the elastic coating layer is bonded. The utility model uses an elastic coating layer to bond directly with the black base fabric layer 2, which can save the dipping adhesive, simplify the composite curtain fabric structure and production process, and not using adhesive also reduces the solvent pollution to the indoor environment. It is suitable for long-term outdoor use and will not cause the problem of adhesive bubbling. Of course, the black base fabric layer 2 of the utility model does not exclude the addition of adhesive, and a small amount of adhesive can also be applied to improve the adhesion firmness. At the same time, a silver elastic coating layer 3 is set to reduce the light transmittance. The black base fabric layer 2 is light and environmentally friendly, has strong weather resistance, strong mechanical properties, good wear resistance, and a long service life. The edge of the coated composite curtain fabric is subjected to high-frequency embossing treatment, which increases the tensile strength and bending resistance, and has a wider range of applications.

[0033] Specifically, the material of the white elastic coating layer 1 is a thermoplastic elastomer, and the raw materials of the thermoplastic elastomer include 90-130 parts of a polyolefin composition, 5-20 parts of an adhesive modifier, 5-15 parts of a silicone masterbatch, 6-12 parts of a white masterbatch, 2-6 parts of a PPA masterbatch, 0.1-3 parts of an antioxidant, and 2-5 parts of an antibacterial masterbatch. The polyolefin composition is POE, PE, PP, and EAA, and the weight ratio of POE, PE, PP, and EAA is (2-6): (2-5): (6-11): (3-8). The peel strength between the white elastic coating layer 1 and the black base fabric layer 2 is not less than 50N / 5cm. The addition of silicone masterbatch and PPA masterbatch to the front white elastic coating layer 1 not only improves the wear resistance of the white elastic coating layer 1 and extends the service life of the product, but also has a certain slippery property, which facilitates surface cleaning.

[0034] The material of the silver elastic coating layer 3 is a thermoplastic elastomer, and the raw materials of the thermoplastic elastomer include 90-130 parts of a polyolefin composition, 5-20 parts of an adhesive modifier, 5-15 parts of a silicone masterbatch, 10-15 parts of a silver powder masterbatch, 2-6 parts of an antibacterial masterbatch, and 0.1-3 parts of an antioxidant. The polyolefin composition is POE, PE, PP, and EAA, and the weight ratio of POE, PE, PP, and EAA is (2-6): (2-5): (6-11): (3-8). The peel strength between the silver elastic coating layer 3 and the black base fabric layer 2 is not less than 50N / 5cm. The silver powder masterbatch containing metal powder is also added to the reverse side of the silver elastic coating layer 3, which can not only reduce the light transmittance and increase the shading degree, but also play a good heat insulation role while shading, greatly improve the wear resistance, and extend the service life of the product. Moreover, the silver powder masterbatch provides antistatic properties, and the surface resistance of the silver elastic coating layer 3 is reduced to 10 6 ~10 8 Ω, avoiding the adsorption of a large amount of dust on the surface of the curtain due to static electricity.

[0035] The adhesive modifier uses the Japanese Mitsui Chemicals Admer adhesive polyolefin resin, the antioxidant uses a hindered phenol antioxidant, and the antibacterial masterbatch uses silver / zinc zeolite and high-temperature resistant organic antibacterial and mildew-proof agent components. The front and back elastic coating layers are modified by adding thermoplastic elastomer materials to improve the flexibility and low-temperature resistance of the composite curtain fabric.

[0036] like Figure 1-Figure 2 As shown, in some embodiments, the weight of the white elastic coating layer 1 is 70-120 g / m 2 The weight of the white elastic coating layer 1 is reasonable. When the weight of the white elastic coating layer 1 is less than 70g / m 2 When the weight of the white elastic coating layer 1 is higher than 120g / m 2 When the thickness of the laminated composite curtain fabric is affected, the winding or bending will be affected. For cost considerations, there is no need to increase the weight to 120g / m 2 above.

[0037] like Figure 1-Figure 2 As shown, in some embodiments, the silver elastic coating layer 3 has a coating weight of 60 to 90 g / m 2 The weight of the silver elastic coating layer 3 is reasonable. When the weight of the silver elastic coating layer 3 is less than 60g / m 2 When the weight of the silver elastic coating layer 3 is higher than 90g / m 2When the thickness of the laminated composite curtain fabric is increased, the winding or bending will be affected, and the shading effect will not be significantly improved. For cost considerations, there is no need to increase the weight to 90g / m 2 above.

[0038] like Figure 1-Figure 2 As shown, in some embodiments, the surface of the white elastic coating layer 1 is a non-smooth texture, and the non-smooth texture is one of fine velvet, coarse velvet, frosted, flash point, diamond silk surface, honeycomb type, and leather texture, and the surface of the silver elastic coating layer 3 is a frosted texture.

[0039] The non-smooth texture of the white elastic coating layer 1 is conducive to forming diffuse reflection, which prevents the white elastic coating layer 1 from being too glaring to the sunlight reflected outdoors.

[0040] like Figure 1-Figure 2 As shown, in some embodiments, the weight of the black base fabric layer 2 is 80 to 180 g / m 2 The thickness of the black base fabric layer 2 has a great influence on the performance of the laminated composite curtain fabric. If the weight of the black base fabric layer 2 is too low, it will affect the physical properties of the laminated composite curtain fabric, such as tensile strength and light-shielding performance. If it is too thick, it will limit the flexibility and application range of the laminated composite curtain fabric. Furthermore, the weight of the laminated composite curtain fabric is 240-360 g / m 2 , small weight, light quality, high tensile strength, good tear resistance, good bending resistance, water and moisture resistance, environmental protection and hygiene.

[0041] like Figure 1-Figure 2 As shown, in some embodiments, the material of the black base fabric layer 2 is at least one of polyester, polypropylene, nylon, spandex, acrylic, ultra-high molecular weight polyethylene fiber, and glass fiber. Generally, nylon base fabric is selected. Nylon material is polyamide commonly known as nylon, which has good comprehensive properties, including mechanical properties, resilience, fatigue resistance and thermal stability, wear resistance, chemical resistance and self-lubrication, and low friction coefficient, which are all helpful to improve the performance of the laminated composite curtain fabric in repeated curling without creases and wear resistance under long-term use.

[0042] like Figure 1-Figure 2 As shown, in some of the embodiments, an adhesive is further provided between the elastic coating layer and the black base fabric layer 2. In some extreme outdoor conditions, such as cold weather, a small amount of adhesive will be applied. At the same time, it is shown that the coating composite curtain fabric of the present invention does not exclude the use of adhesive. Since the elastic coating layer itself can be bonded to the black base fabric layer 2, only a small amount of adhesive is needed to achieve a good effect. Compared with the traditional elastic coating layer, the risk of blistering is smaller.

[0043] The above embodiments are merely descriptions for the purpose of clearly illustrating the present application, and are not limitations on the implementation methods. For technicians in the relevant field, other different forms of changes or modifications can be made based on the above descriptions. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the scope of protection of the present application.
