Description

Technical Field

[0001] The utility model relates to the technical field of spunlace nonwoven materials, and in particular to an intelligent color-changing and insulating spunlace fabric. Background Art

[0002] Placemats, also known as heat-insulating mats, are tableware that protects and decorates the table. They come in a variety of beautiful colors, reminiscent of everyday life. Their strong friction prevents glass and porcelain cups from slipping and protects tabletops from burns. Needle-punched nonwoven fabrics are a type of dry-laid nonwoven fabric. They are made by opening and combing short fibers into a web. This web is then reinforced with needles. The needles have barbs that repeatedly pierce the web, reinforcing the fibers and creating a needle-punched fabric. Needle-punched fabrics are generally thicker, weighing over 80 grams, and have a rough feel and tiny pinholes on the surface. Needle-punched fabrics are often used for placemats, but they have a rough feel and an unattractive appearance. Drop molding technology utilizes the state-shifting properties of thermoplastic polymers—they exhibit viscous flow properties under certain conditions but can return to a solid state at room temperature. Using appropriate methods and specialized tools, inkjet ink is applied to the web, molding it into the desired shape while still in a viscous state. The ink then solidifies at room temperature. Plastic dripping refers to the process of dripping thermoplastic glue onto a product surface through specialized equipment to achieve a specific functional or decorative effect. Due to its anti-slip properties, plastic dripping fabric is also currently used in products such as placemats. Furthermore, if placemats could display the temperature of items placed on them, people would be able to more intuitively determine the temperature of the items, reducing the risk of burns.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of the cross-sectional structure of the intelligent color-changing water-insulating spunlace fabric provided by the utility model. DETAILED DESCRIPTION

[0011] The following will clearly and completely describe the technical solution of the present invention through specific implementation methods. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0012] In the description of this application, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0013] The present application provides an intelligent color-changing water-insulating spunlace fabric, comprising a plurality of intelligent color-changing bodies, a first spunlace fabric layer, a first adhesive layer, a needle-punched fabric layer, a second adhesive layer, and a second spunlace fabric layer arranged in sequence from top to bottom. The first spunlace fabric layer and the needle-punched fabric layer are bonded together by the first adhesive layer, and the second spunlace fabric layer and the needle-punched fabric layer are bonded together by the second adhesive layer. The first spunlace fabric layer is a parallel-laid spunlace fabric, and the second spunlace fabric layer is a cross-laid spunlace fabric.

[0014] The spunlace fabric provided in this application has the functions of intelligent color change, anti-skid and heat insulation, and has a delicate feel and good appearance, and can be used as a heat-insulating and anti-skid mat.

[0015] See also Figure 1 , Figure 1 The figure shows the layered structure of the smart color-changing water-insulating spunlace fabric from the cross-sectional direction, where 1 is the smart color-changing body, 2 is the first spunlace fabric layer, 3 is the first adhesive layer, 4 is the needle-punched fabric layer, 5 is the second adhesive layer, and 6 is the second spunlace fabric layer.

[0016] The smart color-changing water-insulating spunlace fabric provided in the present application includes a plurality of smart color-changing bodies 1, a first spunlace fabric layer 2, a first adhesive layer 3, a needle-punched fabric layer 4, a second adhesive layer 5, and a second spunlace fabric layer 6 arranged in sequence from top to bottom. The first spunlace fabric layer 2 and the needle-punched fabric layer 4 are bonded together by the first adhesive layer 3, and the second spunlace fabric layer 6 and the needle-punched fabric layer 4 are bonded together by the second adhesive layer 5. The first spunlace fabric layer 2 is a parallel-laid spunlace fabric, and the second spunlace fabric layer 6 is a cross-laid spunlace fabric.

[0017] In the embodiment of the present application, the plurality of smart color-changing bodies 1 are a plurality of thermochromic drop-molded bodies. Currently, thermochromic drop-molded cloth is available on the market, and the plurality of smart color-changing bodies 1 are obtained by using thermochromic powder and drop-molding methods known in the art.

[0018] Thermochromic refers to the phenomenon that the color of an object changes with changes in temperature. This phenomenon is caused by the interaction of the object's thermal conductivity and the properties of absorbing, reflecting, and transmitting light. When an object is heated, its temperature rises, and the molecules inside the substance also vibrate due to the temperature change. This vibration causes changes in the interactions between molecules, thereby changing the optical properties of the object. In a preferred embodiment of the present application, Shenzhen Qiansebian New Material Technology Co., Ltd.'s thermochromic powder.

[0019] In the embodiment of the present application, multiple smart color-changing bodies 1 are evenly distributed on the surface of the first spunlace fabric layer 2. Plasticized non-slip nonwoven fabrics are a common type of plasticized nonwoven fabric, and thermochromic plasticized spunlace fabrics are also available on the market. The multiple smart color-changing bodies 1 are the thermochromic plasticized plastics on the surface of the first spunlace fabric layer.

[0020] The first spunlace fabric layer 2 and the needle-punched fabric layer 4 are bonded together by the first adhesive layer 3, and the second spunlace fabric layer 6 and the needle-punched fabric layer 4 are bonded together by the second adhesive layer 5. That is, the first spunlace fabric layer 2 and the second spunlace fabric layer 6 are respectively bonded to the two sides of the needle-punched fabric layer 4.

[0021] Spunlace nonwovens are made by spraying high-pressure, fine water jets onto one or more layers of a fiber web, entangled and reinforced. The resulting fabric is called a spunlace nonwoven. Spunlace has a delicate feel and features fine, longitudinal stripes of spunlace. Needle-punched fabric is thicker and can be used as placemats, but it has a rough feel and an unsightly appearance. Spunlace, on the other hand, has a delicate feel, so layers of spunlace are bonded to both sides of the needle-punched layer to improve the feel and appearance of the placemat.

[0022] The first spunlace layer 2 is a parallel-laid spunlace fabric, and the second spunlace layer 6 is a cross-laid spunlace fabric. Nonwoven spunlace production lines are an efficient and environmentally friendly production technology widely used in healthcare, home furnishing, industrial filtration, and other fields. Laying is a key step in the manufacturing process, determining the quality and performance of the product. Laying methods for nonwoven spunlace production lines include cross-lapping, parallel-lapping, and multi-layer lapping. Each of these methods has its own unique characteristics and is suitable for different production needs. Cross-lapping is one of the most common laying methods in nonwoven spunlace production lines. During the cross-lapping process, the fiber webs are stacked crosswise at a specific angle to form an interwoven structure. This laying method increases the strength and stability of the fiber web, improving the tensile and tear resistance of the product. Cross-lapping is suitable for producing high-strength and high-stability nonwovens. Cross-lapped spunlace fabrics are also called cross-lapped spunlace fabrics. Parallel-lapping is a laying method in which the fiber webs are stacked in parallel. This method reduces the degree of interweaving between the fiber webs, but the fibers are neatly arranged and the surface is smooth. Parallel laying is suitable for producing nonwoven fabrics with smooth and soft surfaces, such as medical gauze and wipes. Parallel-laid spunlace is also called straight-laid spunlace. Multi-layer laying is a process of laying multiple layers of fiber webs together in a certain order and manner. This laying method can increase the thickness and density of the product, improving its thermal insulation and sound insulation properties. Multi-layer laying is suitable for producing thermal insulation materials, sound insulation materials, etc. Because the surface of parallel-laid spunlace has a smooth and flat surface, the first spunlace layer 2 is on the front of the placemat and has multiple intelligent color-changing bodies 1 on the surface, so it is a parallel-laid spunlace. The second spunlace layer 6 is on the back of the placemat, which is a cross-laid spunlace, and the back side has higher strength and better stability.

[0023] In the embodiments of the present application, the first adhesive layer 3 and the second adhesive layer 5 are adhesive layers. In a preferred embodiment of the present application, the adhesive is EDOLAN AH from Shanghai Tuona New Chemical Materials Co., Ltd. The adhesive is applied between the spunlace fabric layer and the needle-punched fabric layer and, after curing, bonds the spunlace fabric layer and the needle-punched fabric layer together.

[0024] Basis weight refers to the weight of a fabric per square meter, usually expressed in grams per square meter (g / m²) or ounces per square yard (oz / yd²). It is an important indicator of fabric thickness and quality, and is of great significance in the production and selection of textiles.

[0025] In summary, this application constructs a layered functional non-woven fabric by using different functional layers and different types of non-woven fabrics, which has the properties of intelligent color change and heat insulation and can be used in thermal insulation pad products.

[0026] In order to better understand the technical content of this application, the following specific examples are provided to further illustrate the spunlace fabric with magnetic function provided by this application. In the following examples, the raw materials used are all commercially available.
