Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to a spunlace nonwoven fabric with a three-dimensional pile on the surface. Background Technology
[0002] The fluff not only enhances the texture of spunlace nonwoven fabric but also makes it softer to the touch. During the production of spunlace nonwoven fabric, an adhesive layer is applied to the surface. The negatively charged fluff is then deposited onto the fabric using the physical property of opposite charges attracting. The fluff in contact with the adhesive is fixed after the adhesive dries, while the fluff in other areas can be blown off.
[0003] In the prior art, utility model patent application number 2022227342426 discloses a spunlace nonwoven fabric with a three-dimensional pile on the surface. It uses a first adhesive layer to fix short fibers and the first pile, and then uses a second adhesive layer to fix the second pile. The amount of adhesive used is large, the cost is high, and it greatly affects the softness of the spunlace nonwoven fabric. Moreover, the process of fixing the second pile is difficult and needs to be improved. Utility Model Content
[0004] The purpose of this invention is to provide a spunlace nonwoven fabric with a three-dimensional pile on the surface, which reduces the amount and cost of adhesives and reduces the difficulty of processing.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A spunlace nonwoven fabric with a three-dimensional pile on its surface includes: a spunlace nonwoven fabric substrate, a first abrasive layer, a first pile, and a first adhesive layer. The first abrasive layer is disposed on the top surface of the spunlace nonwoven fabric substrate. The first adhesive layer is coated on a portion of the surface of the first abrasive layer. The first adhesive layer extends on the first abrasive layer in a straight or curved shape. The first pile is scattered on the first adhesive layer. The first adhesive layer is spaced apart along the width or length direction of the first abrasive layer.
[0007] The spunlace nonwoven fabric matrix is made of biodegradable wood pulp spunlace nonwoven fabric.
[0008] The first adhesive layer is made of water-soluble adhesive.
[0009] The bottom surface of the spunlace nonwoven fabric substrate is provided with a second abrasive layer.
[0010] The length of the first pile is greater than the thickness of the first brushed layer.
[0011] The second abrasive layer is coated with a second adhesive layer that is spaced apart, and the second adhesive layer is covered with second fibers.
[0012] The second adhesive layer is made of water-soluble adhesive, and the length of the second pile is greater than the thickness of the second brushed layer.
[0013] The first and second fibers are made of wood pulp fibers with a length of 2 to 3.8 mm.
[0014] The beneficial effects of this utility model are as follows: A spunlace nonwoven fabric with a three-dimensional pile on the surface, wherein the first brushed layer is formed directly on the surface of the spunlace nonwoven fabric substrate through a brushing process to obtain a first brushed layer composed of short pile, without the need for adhesives, reducing the amount and cost of adhesives, and using the spaced first adhesive layer to fix the first pile, the height difference between the first pile and the short pile in the first brushed layer increases the three-dimensionality, makes the feel richer, has a good anti-slip effect, and is easy to process.

[0016] Figure 2 yes Figure 1 Top view of the first brushed layer;
[0017] Figure 3 This is a schematic diagram of another embodiment of the present invention. Detailed Implementation
[0018] The following is combined Figures 1-3 The technical solution of this utility model will be further illustrated through specific embodiments.
[0019] like Figure 1 The spunlace nonwoven fabric shown has a three-dimensional pile on its surface, comprising: a spunlace nonwoven fabric substrate 1, a first brushed layer 2, a first pile 4, and a first adhesive layer 3. The first brushed layer 2 is disposed on the top surface of the spunlace nonwoven fabric substrate 1. The first brushed layer 2 can be formed directly on the surface of the spunlace nonwoven fabric substrate 1 through a brushing process to obtain a first brushed layer 2 composed of short pile, without the need for adhesive, thus reducing the amount and cost of adhesive.
[0020] The first adhesive layer 3 is applied to a local surface of the first abrasive layer 2. In order to reduce the amount of adhesive used, the first adhesive layer 3 extends on the first abrasive layer 2 in a straight line or curve to reduce the coverage of the first abrasive layer 2.
[0021] The first fibers 4 are spread on the first adhesive layer 3, and the first adhesive layer 3 fixes the first fibers 4 after it dries. In this embodiment, the first adhesive layer 3 is distributed at intervals along the width or length direction of the first abrasive layer 2, such as... Figure 2As shown, the first adhesive layer 3 is distributed at intervals along the length direction of the first abrasive layer 2 and extends to the edge along the width direction of the first abrasive layer 2.
[0022] In this embodiment, the spunlace nonwoven fabric substrate 1 is made of biodegradable wood pulp spunlace nonwoven fabric, which can be buried in the soil for degradation after use, making it more environmentally friendly. The first adhesive layer 3 is made of water-soluble adhesive, which can be dissolved in water, and the first fibers 4 automatically fall off, improving the dispersibility.
[0023] like Figure 1 As shown, the length of the first pile 4 is greater than the thickness of the first brushed layer 2. The first pile 4 is made of wood pulp fiber with a length of 2 to 3.8 mm. The thickness of the first brushed layer 2 is about 1 mm. The height difference between the first pile 4 and the short pile in the first brushed layer 2 increases the three-dimensionality, makes the feel richer, and has a good anti-slip effect.
[0024] like Figure 3 As shown, in this embodiment, the bottom surface of the spunlace nonwoven fabric substrate 1 is provided with a second brushed layer 5. The spunlace nonwoven fabric substrate 1 is processed by a double-sided brushing process to obtain the second brushed layer 5 composed of short fibers.
[0025] A second adhesive layer 6 is coated on the second abrasive layer 5 at intervals, and second fibers 7 are scattered on the second adhesive layer. In this embodiment, the second adhesive layer 6 is made of water-soluble adhesive to fix the second fibers 7, which is more environmentally friendly.
[0026] In this embodiment, the length of the second pile 7 is greater than the thickness of the second brushed layer 5. The second pile 7 is made of wood pulp fiber with a length of 2 to 3.8 mm, and the thickness of the second brushed layer 5 is about 1 mm to increase the three-dimensional effect.
[0027] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
