Description

Technical Field

[0001] This utility model belongs to the field of fabric technology and relates to a foamed black warp-knitted fabric, especially a foamed black warp-knitted fabric with environmental friendliness, high light-blocking ability, smooth appearance and soft hand feel. Background Technology

[0002] In applications such as backdrops, advertising displays, and commercial exhibitions, there are high requirements for the materials used in these displays. These primarily include high light-blocking capability, requiring 100% light blocking to prevent light transmission and whitening, which would negatively impact visual effects. High surface flatness and mechanical properties are also essential to ensure a smooth image and easy installation. Good tear resistance and dimensional stability are also crucial to prevent deformation. Additionally, the fabric should be lightweight and possess a certain degree of flexibility for ease of manufacturing. Existing ordinary coated fabrics are stiff, heavy, and have poor drape, as well as shortcomings in light blocking, breathability, and environmental friendliness. Therefore, designing a foamed black warp-knitted fabric that simultaneously achieves environmental friendliness, high light blocking, a soft feel, and structural stability and durability is highly necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foamed black-coated warp-knitted fabric.

[0004] To achieve the above objectives, the technical solution of this utility model is: a foamed black warp-knitted fabric, which is composed of four layers, including: a base fabric layer of polyester warp-knitted fabric, a foamed resin layer, a black foam layer and a surface treatment layer. Each layer is fused into an integral structure through a coating treatment. The base fabric layer is woven from yarns of two guide bars, GB1 and GB2, using a warp knitting method. The raw material of GB1 is 50D / 24F FDY filament, and the raw material of GB2 is 75D / 36FDTY elastic yarn. The weaving density is 20M / cm. The warp count of GB1 is 612*7 heads, the warp count of GB2 is 612*7 heads, the padding yarn number of GB1 is 12 / 10, and the padding yarn number of GB2 is 10 / 34.

[0005] The base fabric layer has a weight of 140-200 g / m², and the structure of the base fabric layer is a double-combed warp weave.

[0006] The foamed resin layer is a water-based coating layer, and the weight of the foamed resin layer is 45-70 grams per square meter.

[0007] The black foam layer is a black slurry foam coating with a weight of 40-65 grams per square meter and a light-blocking degree of 100%.

[0008] The surface treatment layer has a weight of 35-55 grams per square meter.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are: 1. The addition of a black foam coating structure achieves a stronger light-blocking effect, enabling 100% complete light blocking.

[0010] 2. The structural stability of warp-knitted fabric, combined with the penetration effect of the foamed resin layer, further locks in the yarn, increasing the fabric's tear resistance and durability. At the same time, the foamed resin layer makes the fabric lighter, softer, and more elastic at the same thickness. When combined with warp-knitted fabric, it has a softer feel and better drape.

[0011] 3. To achieve the same functional effect, the combination of the foamed resin layer and the black foam layer makes the overall weight of the fabric lighter, thus achieving a lightweight function. Attached Figure Description

Detailed Implementation

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] like Figure 1-3 As shown, this foamed black warp-knitted fabric is composed of four layers: a base fabric layer 10 of polyester warp-knitted fabric, a foamed resin layer 20, a black foam layer 30, and a surface treatment layer 40. Each layer is fused into a whole structure through a coating treatment. The base fabric layer 10 is woven from the yarns of two guide bars, GB1 and GB2, using a warp knitting method. The raw material of GB1 is 50D / 24F FDY filament, and the raw material of GB2 is 75D / 36F DTY elastic yarn. The weaving density is 20M / cm. The warp count of GB1 is 612*7 heads, and the warp count of GB2 is 612*7 heads. The padding yarn number of GB1 is 12 / 10, and the padding yarn number of GB2 is 10 / 34.

[0015] In practice, the feed rate is GB1: 1350mm / Rack, GB2: 2250mm / Rack, and the speed is 1600 rpm.

[0016] The base fabric layer 10 has a weight of 140-200 g / m² and a double comb warp weave structure, which gives it high dimensional stability, high strength, and good flatness, ensuring the surface structure stability and durability of the blackened warp-knitted fabric.

[0017] The foamed resin layer 20 is a water-based coating layer with a weight of 45-70 g / m². The foamed resin layer 20 is coated using commercially available products. The coating slurry mainly consists of environmentally friendly water-based polyacrylate, foaming agent, flame retardant, etc. This coating maintains the soft touch and good drape of the textile through direct and close integration with the base fabric, ensuring the surface printing effect of the fabric.

[0018] The black foam layer 30 is a black slurry foam coating with a weight of 40-65 grams per square meter and a light-blocking degree of 100%. The black foam layer 30 is coated with existing products available on the market. The coating slurry mainly consists of environmentally friendly water-based resin, titanium dioxide, black slurry additives, etc.

[0019] The surface treatment layer 40 has a weight of 35-55 grams per square meter. The surface treatment layer 40 is coated with existing products available on the market. The coating slurry mainly consists of acrylic ester, flame retardant, antistatic agent, etc., which enhances the product's wear resistance, water resistance, weather resistance, flame retardancy and other properties.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
