Technical Field

[0001] The invention relates to the technical field of carpet manufacturing, and in particular to an easily washable and detachable carpet and a preparation method thereof. Background Art

[0002] Carpet is a high-end floor decoration material made of animal hair, plant hemp, synthetic fiber, etc., through weaving, cutting and other processing processes. Carpets are soft, comfortable to the feet and safe to use. They are particularly suitable for floor decoration in bedrooms, living rooms and study rooms in the home. In home decoration, carpets can achieve satisfactory decorative effects when they are fully covered or used as partial decorations on the floor. Carpets are easy to hide dust and breed bacteria after being trampled. As they are used for a long time, they will become more and more dirty, causing human discomfort and even skin allergies and inflammation. Therefore, carpets need to be washed and cleaned after a period of use. Because carpets are thick and the weight of water absorption increases significantly during washing, it is extremely inconvenient to wash them. Frequent replacement of new carpets also causes a waste of resources and does not conform to the concept of low-carbon and environmentally friendly life.

[0003] Therefore, there is an urgent need for a carpet that is easy to clean. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned existing carpets that are generally difficult to clean and inconvenient to maintain, and to provide a washable and detachable carpet, the surface layer and the bottom layer of which are detachable.

[0035] Please refer to Figures 1 to 5 , showing a washable and detachable carpet according to the present embodiment, which includes a surface layer 1 and a bottom layer 2, wherein the bottom layer 2 is at the bottom, and the surface layer 1 is detachably connected to the bottom layer. The surface layer is a warp-knitted suede-like fabric layer, including a first pile surface 12 composed of a first pile 11. The bottom layer is a single-sided cut pile fabric layer, including a second pile surface 22 composed of a second pile 21, and the second pile 21 is inclined, that is, inclined at a certain angle relative to the horizontal plane. The first pile surface 12 faces the second pile surface 22, and the first pile 11 penetrates into the second pile 21 and hooks with the second pile 21. Specifically, the first pile and the second pile are hooked at the root of the second pile, and the angle formed by the first pile and the second pile is 45° to 75°.

[0048] Specific embodiment parameters:

[0049]

[0050]

[0051] Performance Test:

[0052] (1) Peel strength: The peel strength between the surface layer and the bottom layer is determined in accordance with GB / T 26843-2011 “Test for the peel strength of carpet backing”;

[0053] (2) Relative sliding performance between the surface layer and the bottom layer: Lay the carpet flat on the ground and have an adult step on the carpet for 10 minutes. Then observe whether there is relative displacement between the edge of the surface layer and the bottom layer, and record the relative displacement.

[0054] Level 1: The connection between the surface layer and the bottom layer is stable without any relative sliding displacement;

[0055] Level 2: The connection between the surface layer and the bottom layer is basically stable, and there is a slight displacement between the edge of the surface layer and the bottom layer, with the displacement distance ≤1mm;

[0056] Level 3: The connection between the surface layer and the bottom layer is generally stable. There is relative displacement between the edge of the surface layer and the bottom layer, but it does not affect the use. 1mm<displacement distance≤3mm;

[0057] Level 4: The connection between the surface layer and the bottom layer is unstable, and there is a relative displacement between the edge of the surface layer and the bottom layer that affects the use, and the displacement distance is greater than 3mm;

[0058] Level 5: The connection between the surface layer and the base layer is unstable, resulting in obvious displacement, with the displacement distance being >3mm.

[0059] The performance test results are shown in the following table:

[0060]

[0061]

[0062] From the above performance test results, it can be seen that the surface layer and bottom layer of the washable and detachable carpet of the present invention can be made into a surface layer and a bottom layer that can be hooked together by selecting a combination of polyester, nylon island fiber and polypropylene fiber. It is difficult to make a surface layer and a bottom layer that can be hooked together by selecting other fabrics; the stability of the hooking connection between the surface layer and the bottom layer is also highly correlated with the sanding, perming and heating angles, and the pile of either the surface layer or the bottom layer cannot be too short. The surface layer is sanded with 650 mesh sandpaper, permed at 130°C, and the second pile is tilted at 45°, so that the surface layer and the bottom layer can be stably hooked together.
