[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] The term "comprising" and other similar descriptions in the specification and claims of the present application are intended to cover the non-exclusive inclusion, that is, to include the contents explicitly described in the specification and claims, and also to include the steps or units not described in the specification and claims but inherent in the product, method or structure.

[0035] Please refer to Figures 1 to 5 , which shows a detachable easy-to-clean carpet in the embodiment, which comprises a face layer 1 and a bottom layer 2, the bottom layer 2 is below, and the face layer 1 is detachably connected on the bottom layer. The face layer is a warp-knitted suede fabric layer, which comprises a first pile surface 12 composed of first pile 11. The bottom layer is a single-face cut-pile fabric layer, which comprises a second pile surface 22 composed of 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 hooks with the second pile at the root of the second pile, and the included angle formed by the first pile and the second pile is 45°-75°.

[0037] In the embodiment, the bottom of the single-face cut-pile fabric layer is provided with anti-skid silica gel to prevent the bottom layer from sliding relative to the ground during use.

[0038] In the embodiment, the face layer 1 has a grammage of 300-600 g / m 2 and a thickness of 3-10 mm; and the bottom layer 2 has a grammage of 300-600 g / m 2, the thickness is 3mm-10mm; the first pile 11 is polyester or chinlon fiber, the fineness is 0.1dtex-0.6dtex, the density of the first pile 11 is 400-1600 root / cm 2 ; the second pile 21 is polyester or propylene fiber, the fineness is 100dtex-500dtex, the density of the second pile 21 is 625-2500 root / cm 2 , the initial modulus of the second pile is >60cN / dtex. The first pile 11 is superfine fiber, the fineness is thin and the shape is crimped, while the initial modulus of the second pile is large, has rigidity and is in an inclined shape, so the first pile 11 can easily penetrate into the second pile 21 and hook with the second pile 21, so that the surface layer 1 cannot slide apart from the bottom layer 2, but the first pile 11 can be easily separated from the second pile 21 by force due to the thin and crimped first pile 11. The detachable connection of the surface layer and the bottom layer is realized by the shape and connection structure of the first pile 11 and the second pile 21.

[0039] The detachable carpet of the present embodiment is prepared by the following method:

[0040] Preparation of the surface layer: 100-160dtex polyester or chinlon sea-island filament is selected as raw material for warp knitting, the warp knitting structure is 5 satin or 6 satin; then alkali reduction treatment is carried out by using alkali solution; then after setting, single-side sanding is carried out to form the first pile;

[0041] Preparation of the bottom layer: 100dtex-500dtex polyester or propylene fiber is selected for weaving; after weaving, brushing is carried out to make the pile stand upright; then ironing is carried out, and the heating plane is inclined to the pile during ironing, so that the pile after ironing is in an inclined shape to form the second pile; please refer to Figure 6 , during ironing, the heating plane 30 forms an angle a with the second pile surface 22, then the second pile 21 is horizontally transmitted and contacts the heating plane 30 to be heated, so that the second pile 21 is inclined by an angle a relative to the horizontal plane.

[0042] Pressing: the second pile of the bottom layer is upward, the first pile of the surface layer is downward, and the surface layer is pressed onto the bottom layer by a pressing roller, so that the first pile is crimped into the second pile and connected with each other.

[0043] In the present embodiment, during preparation of the surface layer, the alkali solution for alkali reduction is NaOH, the concentration is 1-5g / L, the temperature is 100-150℃, and the treatment time is 30-60min; the setting temperature is 150-180℃, and the time is 15-30min; the sandpaper for sanding is 600mesh-650mesh.

[0044] In the embodiment, when preparing the bottom layer, the temperature of the ironing treatment is 120-150℃, the ironing time is 1-10s, and the ironing is performed by using a soldering iron heating plane, and the soldering iron heating plane is at an angle of 45-75° with the second pile.

[0045] In the embodiment, when preparing the bottom layer, the standing pile is first trimmed before ironing, so that the length of the pile is 1-5mm.

[0046] In the embodiment, when pressing, normal temperature pressing rollers are used, and the pressure is 10-50N / m 2 .

[0047] In the embodiment, the bottom surface of the bottom layer is also subjected to point anti-slip silicone treatment, and the specific method is as follows: TPU or EVA glue particles are put into a glue barrel of a dispensing machine, the glue barrel is heated to 150℃ to melt and stir the glue particles uniformly; a dispensing needle head with a diameter of 2-3mm is selected to perform dispensing, the dispensing air pressure is 0.5-0.7Mpa, the dispensing time is 0.1-0.5s, the warp and weft dispensing intervals are both 3-6cm, the shape is circular, the array type arrangement is adopted, and the density is 400-500 / m 2 .

[0048] Specific example parameters:

[0049]

[0050]

[0051] Performance test:

[0052] (1) Peeling strength: the peeling strength of the surface layer and the bottom layer is tested according to GB / T 26843-2011 “Determination of carpet backing peel strength test”;

[0053] (2) Relative sliding performance of the surface layer and the bottom layer: the carpet is laid on the ground, an adult steps on the carpet for 10 minutes, and then whether the relative displacement of the edge of the surface layer and the bottom layer occurs is observed, and the relative displacement is recorded.

[0054] First level: the connection between the surface layer and the bottom layer is stable, and there is no any relative sliding displacement;

[0055] Second level: the connection between the surface layer and the bottom layer is basically stable, the edge of the surface layer and the bottom layer slightly displace, and the displacement distance is ≤1mm;

[0056] Third level: the connection between the surface layer and the bottom layer is generally stable, the edge of the surface layer and the bottom layer relatively displace, but does not affect the use, 1mm

[0057] Fourth level: the connection between the surface layer and the bottom layer is unstable, the edge of the surface layer and the bottom layer relatively displace, which affects the use, and the displacement distance is >3mm.

[0058] Level 5: the connection between the surface layer and the bottom layer is unstable, and obvious displacement occurs, with a displacement distance > 3mm.

[0059] The performance test results are as follows:

[0060]

[0061]

[0062] From the above performance test results, it can be seen that the surface layer and the bottom layer of the easy-to-wash detachable carpet can be made to be connected to each other by selecting polyester, spandex island, and polypropylene fiber combinations. It is difficult to make the surface layer and the bottom layer that can be connected to each other by selecting other fabrics. The stability of the surface layer and the bottom layer connected to each other is also relatively large in relation to sanding, ironing, and heating angle, and the pile of any layer of the surface layer and the bottom layer cannot be too short. The surface layer is sanded with 650 mesh sandpaper, ironed at 130 DEG C, and the second pile is inclined at 45 DEG, so that the carpet with the surface layer and the bottom layer connected to each other stably can be obtained.
