Preparation method of Uyghur flower mat non-slip summer mat

Abstract

The application discloses a preparation method of a Uyghur floral mat anti-skid summer mat, and relates to the technical field of summer mat preparation. The intermediate reinforcing layer is laid on the back of the floral mat main layer, and the floral mat main layer and the intermediate reinforcing layer are punctured and combined, so that part of the fibers in the floral mat main layer penetrates through the intermediate reinforcing layer and is exposed on the back of the intermediate reinforcing layer, forming longitudinal fiber anchor columns, and a composite containing the floral mat main layer, the intermediate reinforcing layer and the longitudinal fiber anchor columns is obtained. Thus, the traditional mode of only relying on surface adhesion to maintain the anti-skid layer is changed into a connection mode with structural force transmission and local locking, which is more conducive to reducing the local warping of the anti-skid locking layer, the falling of silica gel points, the interlayer loosening and the laying position deviation, especially in the scenes of edge stress, turning and dragging and washing and airing, and the edge flatness, the interlayer close adhesion and the anti-skid continuity can be more easily maintained.

Description

Technical Field

[0001] This invention relates to the field of cooling mat preparation technology, specifically a method for preparing a Uyghur floral felt anti-slip cooling mat. Background Technology

[0002] Felt materials themselves possess characteristics such as thick fibers, a soft surface, strong pattern-bearing capacity, and a unique tactile feel. Especially in Uyghur felt products, these characteristics are closely integrated with decorative patterns. Combined with processing steps such as felting, printing, needle punching, and hot pressing, they have the technological foundation to continue developing towards stable laying, repeated use, and mass production. Therefore, developing a mat-making technology that balances cultural expression, slip resistance, and structural durability based on felt materials has become a specific technological direction for the improvement of felt-based home furnishings.

[0003] In the actual use of felt materials, especially Uyghur felt materials, the main layer of the felt will be repeatedly compressed and rebounded and displaced between layers due to pressure from sitting and lying down, turning over and dragging, rolling and storing, and washing and drying. If the anti-slip layer is still mainly on the back of the middle reinforcement layer or the surface of the substrate, and does not form a penetrating lock with the main layer of the felt along the thickness direction, then the interface will be subjected to repeated shear and peel loads for a long time. This can easily lead to problems such as local lifting of the anti-slip layer, loosening of the interface, shear separation of anti-slip points, reduction of anti-slip effect, and displacement of the laying position. Furthermore, it can also lead to abnormal results such as edge curling, unstable tactile feel, and decreased durability. Summary of the Invention

[0004] This invention provides a method for preparing a Uyghur floral felt anti-slip cooling mat, which solves the problems mentioned in the background art.

[0005] A method for preparing a Uyghur floral felt anti-slip cooling mat includes the following steps: S1. Wool fibers and recycled fibers are mixed and rolled into felt, and then stamped with a die-stamping process. The resulting felt layer is then needle-punched and interwoven, followed by a first hot-pressing process to obtain the main felt layer. S2. An intermediate reinforcement layer is laid on the back of the main felt layer, and the main felt layer and the intermediate reinforcement layer are punctured together, allowing some fibers in the main felt layer to pass through the intermediate reinforcement layer and protrude from its back, forming longitudinal fiber anchors. This results in a composite containing the main felt layer, the intermediate reinforcement layer, and the longitudinal fiber anchors. S3. A drip molding process is performed on the back of the intermediate reinforcement layer to cover and encapsulate the exposed fiber segments of the longitudinal fiber anchors that pass through the back of the intermediate reinforcement layer, forming an anti-slip locking layer with the back of the intermediate reinforcement layer. The composite is then cured. S4. The cured composite is subjected to a second hot-pressing process, and then cut to the target specifications to obtain a non-slip floral felt mat.

[0006] Preferably, the mass ratio of the wool fiber to the regenerated fiber is 6:4; the thickness of the main layer of the felt after the first hot pressing is 3-4 mm.

[0007] Preferably, the pattern formed by the stamping is either an almond flower pattern or a scroll pattern; the temperature of the first hot pressing is 120-140℃.

[0008] Preferably, when the main body layer of the floral felt and the intermediate reinforcing layer are punctured and bonded, the puncture direction is from the main body layer of the floral felt to the intermediate reinforcing layer; the portion of the longitudinal fiber anchor that passes through the back side of the intermediate reinforcing layer is an exposed fiber segment, which can be covered and wrapped by the anti-slip locking layer.

[0009] Preferably, the intermediate reinforcing layer is a non-woven fabric layer; the weight of the non-woven fabric layer is 80-100 g / m²; the non-woven fabric layer is laid flat on the back of the main body of the felt and serves as the penetrating support layer for the longitudinal fiber anchor.

[0010] Preferably, the anti-slip locking layer is formed by dripping food-grade silicone into silicone dots, and the silicone dots have a diameter of 2.0 mm, a dot spacing of 3-5 mm, and a height of 0.8-1.0 mm; the anti-slip locking layer is cured at room temperature for 24 hours.

[0011] Preferably, the temperature of the second hot pressing is 100-120℃, the hot pressing pressure is 0.2-0.3MPa, and the hot pressing time is 30s; the second hot pressing is used to press the interlayer bonding area between the main layer of the felt, the intermediate reinforcing layer and the anti-slip locking layer.

[0012] Preferably, the silicone dots are arranged in a manner corresponding to the distribution positions of the exposed fiber segments on the back side of the intermediate reinforcing layer; each silicone dot covers one or more of the exposed fiber segments to form multiple dispersed anti-slip locking units.

[0013] This invention provides a method for preparing a Uyghur floral felt anti-slip cooling mat, which has the following beneficial effects: 1. By mixing 38mm long, 21μm fine wool fibers with 51mm long, 1.5D fine recycled polyester fibers to form the main layer of the felt, and forming a longitudinal fiber anchor through piercing composite from the main layer of the felt to the intermediate reinforcement layer composed of a polyester nonwoven fabric layer with a surface density of 90g / ㎡, the exposed fiber segments are then covered and wrapped with food-grade silicone drip molding. Finally, a second hot pressing is used to form a penetrating and locking connection between the main layer of the felt, the intermediate reinforcement layer, the longitudinal fiber anchors, the exposed fiber segments, and the anti-slip locking layer. This transforms the traditional method of maintaining the anti-slip layer by relying solely on surface adhesion into a connection method that combines structural force transmission and local locking. This is more conducive to reducing local lifting of the anti-slip locking layer, silicone point detachment, interlayer loosening, and laying position deviation. Especially in scenarios such as edge and corner stress, turning and dragging, and washing and drying, it is easier to maintain smooth edges, tight interlayer adhesion, and anti-slip continuity.

[0014] 2. By limiting the mass ratio of wool fiber to recycled polyester fiber to 6:4, and limiting the pattern formed by stamping to either almond flower or scroll pattern, while limiting the temperature of the first hot pressing to 120-140℃ and the thickness of the main body layer of the felt after the first hot pressing to 3-4mm, the main benefit of these conditions is that they can improve the stability of the forming quality of the front end of the main body layer of the felt. That is, while ensuring the continuity of wool fiber felting, the recycled polyester fiber is used to improve the dispersion uniformity and dimensional stability of the fiber network. This allows the main body layer of the felt to have a more uniform thickness, clearer pattern boundaries, and a more stable internal fiber support state before entering the subsequent piercing and laminating process. This reduces the problems of local thinning, local hardening, blurred pattern edges, and discontinuous fiber pulling during batch production, and is more conducive to obtaining a semi-finished felt anti-slip mat with a stable appearance and less process fluctuation.

[0015] 3. By limiting the puncture direction to from the main felt layer to the intermediate reinforcing layer, defining the intermediate reinforcing layer as a non-woven fabric layer with a basis weight of 80-100 g / m², and defining the anti-slip locking layer as a silicone dot structure formed by dripping food-grade silicone, with silicone dots having a diameter of 2.0 mm, a dot spacing of 3-5 mm, and a height of 0.8-1.0 mm, and then curing at room temperature (23℃, 50% relative humidity) for 24 hours, the main benefit of these conditions is that they can improve the shape of the longitudinal fiber anchors and exposed fiber segments. The stability and consistent distribution of the anti-slip locking units make it easier for some fibers in the main layer of the felt to pass through the intermediate reinforcing layer and form exposed fiber segments suitable for being covered and wrapped. At the same time, the non-woven fabric layer provides continuous penetrating support. Combined with the point-to-point coverage and locking of silicone dots, it is more conducive to avoiding the problem of insufficient anti-slip in some areas on the back, local loosening or curling, thereby improving the uniformity of use of the entire felt anti-slip mat in corner areas, turning areas and frequently pressured areas, as well as the anti-slip continuity after multiple washes.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1 This invention provides a method for preparing a Uyghur floral felt anti-slip cooling mat. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 This includes the following steps: S1. Wool fibers and recycled fibers are mixed and rolled into felt, and then stamped with a die-stamping process. The resulting felt layer is then needle-punched and interwoven, followed by a first hot-pressing process to obtain the main felt layer. S2. An intermediate reinforcement layer is laid on the back of the main felt layer, and the main felt layer and the intermediate reinforcement layer are punctured together, allowing some fibers in the main felt layer to pass through the intermediate reinforcement layer and protrude from its back, forming longitudinal fiber anchors. This results in a composite containing the main felt layer, the intermediate reinforcement layer, and the longitudinal fiber anchors. S3. A drip molding process is performed on the back of the intermediate reinforcement layer to cover and encapsulate the exposed fiber segments of the longitudinal fiber anchors that pass through the back of the intermediate reinforcement layer, forming an anti-slip locking layer with the back of the intermediate reinforcement layer. The composite is then cured. S4. The cured composite is subjected to a second hot-pressing process, and then cut to the target specifications to obtain a non-slip floral felt mat.

[0019] Preferably, wool fibers with a length of 38 mm and a fineness of 21 μm and recycled polyester fibers with a length of 51 mm and a fineness of 1.5 D are selected as raw materials, mixed at a mass ratio of 6:4, and then rolled into felt after opening, carding and cross-laying to obtain the initial felt layer. The initial felt layer density is controlled at 780 g / ㎡ and the initial thickness is controlled at 5.2 mm. Then, an almond pattern is formed on the surface of the initial felt layer using a stamping process. The stamping pressure is controlled at 0.18 MPa and the holding time is controlled at 8 seconds to ensure that the surface pattern is clear and does not damage the fiber continuity. After the stamping is completed, the initial felt layer is needle-punched and interwoven, with the needle-punching density controlled at 210 needles / cm² and the needle-punching depth controlled at 6mm. Then, the first hot pressing is carried out at 130℃ for 35s, resulting in a 3.6mm thick felt main body layer.

[0020] The intermediate reinforcement layer is made of polyester nonwoven fabric with a surface density of 90g / ㎡. After the nonwoven fabric layer is laid flat on the back of the main flower felt layer, it is punctured and bonded. The puncture direction is from the main flower felt layer to the intermediate reinforcement layer. The needle density is controlled at 160 needles / cm² and the needle depth is controlled at 4.5mm. This allows some fibers in the main flower felt layer to pass through the intermediate reinforcement layer and be exposed on the back of the intermediate reinforcement layer, forming dispersed longitudinal fiber anchors.

[0021] Microscopic observation revealed that the average length of the exposed fiber segments was 0.7 mm, and the number of longitudinal fiber anchors per unit area was approximately 115 per 100 cm². Subsequently, food-grade silicone was drip-molded onto the back of the intermediate reinforcement layer. The nozzle diameter of the dripping head was controlled at 2.0 mm, the dot spacing at 4 mm, and the dot height at 0.9 mm, so that the silicone material covered and encapsulated the exposed fiber segments, while simultaneously connecting with the back of the intermediate reinforcement layer to form an anti-slip locking layer. After drip molding, the material was allowed to stand at 23°C for 24 hours to cure. After curing, a second hot-pressing shaping was performed at 110℃ and 0.25MPa, with the hot-pressing time controlled at 30s. The samples were then cut into 600mm×1200mm samples to verify the effectiveness of the longitudinal fiber anchor penetration locking preparation method.

[0022] Four comparative examples were set up at the same time: Comparative example 1 canceled the puncture composite to form a longitudinal fiber anchor column, and only dripped plastic was directly applied to the back of the intermediate reinforcement layer. Comparative Example 2 retains the puncture composite but removes the intermediate reinforcement layer, and only drip-moldes the back of the main flower felt layer; Comparative Example 3 retains the longitudinal fiber anchor and drip molding process but eliminates the second hot pressing and shaping. Comparative Example 4 uses a sample made with conventional commercially available non-slip cooling mat technology; The test items include interlayer peel strength, static friction coefficient, silicone dot shedding rate, anti-slip retention rate after 20 washes, delamination length after 50 folds, and laying displacement. The test environment is 23℃ and 50% relative humidity. The specific results of the four comparative experiments are summarized in Table 1. Table 1: Comparison of the effects of Example 1 and Comparative Examples 1-4; Parameter name Example 1 - Method for preparing longitudinal fiber anchor pins through-locking Comparative Example 1 - Direct drip molding without longitudinal fiber anchors Comparative Example 2 - Backside drip molding without intermediate reinforcement layer Comparative Example 3 - No Second Hot Pressing for Shaping Comparative Example 4 - Regular Commercially Available Non-Slip Cooling Mat Thickness of the main layer of the felt (mm) 3.6 3.6 3.5 3.6 3.2 Number of longitudinal fiber anchors (per 100cm²) 115 0 78 112 0 Interlayer peel strength (N / 50mm) 38.6 19.4 16.8 27.2 14.5 static friction coefficient 0.86 0.63 0.58 0.74 0.6 Silicone dot detachment rate (%) 2.8 14.6 18.9 7.5 16.2 Anti-slip retention rate (%) after 20 washes 91.5 72.8 68.4 82.6 70.1 Layer length after 50 folds (mm) 2.1 11.8 15.6 6.9 13.4 Laying displacement (mm) 4.3 12.7 15.2 8.1 13.6 From Table 1 above: Comparison of the effects of Example 1 and Comparative Examples 1-4, it can be seen that Example 1 is significantly better than the four comparative examples in multiple indicators, indicating that the longitudinal fiber anchor penetration and locking preparation method is not a simple replacement of the ordinary back-side drip molding process, but forms a new process effect in terms of connection path and force transmission method. First, let's look at the interlayer peel strength. Example 1 reached 38.6 N / 50 mm, while Comparative Example 1 was only 19.4 N / 50 mm, Comparative Example 2 was only 16.8 N / 50 mm, and Comparative Example 4 was only 14.5 N / 50 mm. The above differences in interlayer peel strength illustrate: When some fibers in the main layer of the felt pass through the intermediate reinforcement layer and form longitudinal fiber anchors, the interlayer external force is no longer concentrated on the plane interface between the intermediate reinforcement layer and the anti-slip locking layer. The external force will be further transmitted to the interior of the main layer of the felt by the longitudinal fiber anchors, thus significantly improving the interlayer anti-peeling ability.

[0023] Looking at the silicone dot detachment rate, Example 1 had a rate of only 2.8%, while Comparative Example 1 reached 14.6%, Comparative Example 2 reached 18.9%, and Comparative Example 4 reached 16.2%. The above silicone dot detachment rate results illustrate: After the exposed fiber segments are covered and encased by the anti-slip locking layer, the silicone dots no longer rely solely on surface adhesion, but instead form a binding and locking effect on the longitudinal fiber anchors. Therefore, it is more difficult for them to peel off or fall off under repeated friction and folding conditions.

[0024] In terms of static friction coefficient and laying displacement, Example 1 achieved 0.86 and 4.3 mm respectively, Comparative Example 1 achieved 0.63 and 12.7 mm respectively, and Comparative Example 4 achieved 0.60 and 13.6 mm respectively. The differences in static friction coefficient and laying displacement mentioned above illustrate: Example 1 not only maintains a more stable anti-slip layer, but also ensures a more complete overall fit between the anti-slip locking layer and the intermediate reinforcing layer. Therefore, it can continuously provide high friction in a planar contact state, preventing the felt anti-slip mat from slipping significantly on the bed or sofa surface.

[0025] The anti-slip retention rate after 20 washes is a key indicator for verifying durability. Example 1 achieved 91.5%, which is higher than Comparative Example 1's 72.8%, Comparative Example 2's 68.4%, and Comparative Example 4's 70.1%. The above anti-slip retention rate results after 20 washes indicate that: The longitudinal fiber anchor penetration locking method can still maintain high anti-slip performance after washing, indicating that the anti-slip locking layer and the main layer of the felt are not a one-time surface adhesion relationship, but a stable penetration locking relationship.

[0026] Regarding the layer length after 50 folds, Example 1 had a layer length of only 2.1 mm, while Comparative Example 1 had 11.8 mm, Comparative Example 2 had 15.6 mm, and Comparative Example 3 had 6.9 mm. The difference in layer length after 50 folds illustrates that the second hot-pressing has a significant effect. Although Comparative Example 3 has longitudinal fiber anchors and anti-slip locking layers, the layer length is still significantly higher than that of Example 1 after the second hot-pressing is removed. This indicates that the second hot-pressing has a significant promoting effect on pressing the interlayer bonding area and stabilizing the penetration locking connection.

[0027] It should be noted that: interlayer peel strength is used to indicate the degree of bonding between the main layer of the floral felt and the composite layer consisting of the intermediate reinforcing layer and the anti-slip locking layer. In the specific test, strip samples with a width of 50mm and a length of 180mm are cut from the finished floral felt anti-slip cooling mat in the central area and the four corner areas respectively. One end of each strip sample is pre-split by 30mm to form the clamping end of the main layer of the floral felt and the clamping end of the composite layer. The composite layer clamping end includes an intermediate reinforcing layer, an anti-slip locking layer, and an exposed fiber segment covered and wrapped by the anti-slip locking layer. Then, the main layer clamping end and the composite layer clamping end are clamped in the upper and lower clamps of an electronic tensile testing machine. Under an environment of 23±2℃ and 50±5% relative humidity, tensile peeling is performed in a 180° peeling manner. The peeling speed is set to 100mm / min. The continuous peeling force data within the peeling stroke range of 50mm to 120mm is recorded, and the arithmetic mean of the peeling force within this range is taken as the interlayer peel strength test result of a single strip sample, with the unit recorded as N / 50mm. The average value of the test results of five strip samples of the same sample is then taken as the interlayer peel strength of the sample. The reason for adopting the above test method is that the longitudinal fiber anchors and exposed fiber segments form a penetrating and locking connection between the main layer of the felt and the intermediate reinforcement layer and the anti-slip locking layer. Therefore, testing the main layer of the felt and the composite layer as the two ends of the peel can reflect the actual improvement effect of the longitudinal fiber anchors, exposed fiber segments and anti-slip locking layers on the interlayer bonding stability.

[0028] The static friction coefficient is used to represent the anti-slip ability of the anti-slip locking layer on the back of the finished floral felt anti-slip cooling mat to the surface of the substrate at the moment of slippage. In the specific test, square samples with a length of 100mm and a width of 100mm are cut from the center area and four corner areas of the finished floral felt anti-slip cooling mat. Each square sample retains the integrity of the anti-slip locking layer and is placed with the anti-slip locking layer facing down on a flat, painted wooden test platform to simulate the common laying conditions of bed boards, sofa bases, or bay window sills. After standing for 2 hours in an environment of 23±2℃ and 50±5% relative humidity, a 2kg loading block is placed on top of the sample to create a stable normal pressure between the sample and the test platform. Then, an electronic push-pull force gauge is used to apply force uniformly in the horizontal direction at a controlled speed of 1... The maximum tensile force was recorded at 00 mm / min, indicating the moment the sample transitioned from a static state to the point of initiation of slippage. This maximum tensile force was then divided by the normal load corresponding to the total weight of the sample and the loading block to obtain the static friction coefficient of a single sample. The average value of the test results for the five square samples was then taken as the static friction coefficient of the sample. The reason for using the above test method is that the anti-slip improvement of this scheme focuses on covering the exposed fiber segments through the anti-slip locking layer. This allows the anti-slip locking layer to maintain both surface friction capability and structural stability associated with the longitudinal fiber anchor under pressure contact. Therefore, calculating the static friction coefficient based on the instantaneous resistance between the back anti-slip locking layer and the common laying carrier is more effective in reflecting the suppression effect of this scheme on initial slippage under actual laying and use conditions.

[0029] Silicone dot detachment rate is used to indicate the proportion of silicone dots in the anti-slip locking layer that detach from the back of the middle reinforcing layer or are obviously damaged after repeated friction. During the specific test, square samples with a length of 100mm and a width of 100mm were cut from the center area and the four corner areas of the finished anti-slip mat. Each square sample kept the anti-slip locking layer intact. First, all the silicone dots on the back of the square sample were photographed and counted. The number of silicone dots with complete outlines and continuous attachment to the back of the middle reinforcement layer was recorded as the initial number of silicone dots. Then, the square sample was placed on the lacquered wooden test table with the anti-slip locking layer facing down. A 2kg loading block was applied above the sample, and a reciprocating friction tester was used for friction testing. The friction stroke was set to 100mm, and the friction frequency was set to 60 times / min. After 1000 consecutive friction cycles, the sample was removed, and the silicone dots on the back of the square sample were photographed and counted again. Silicone dots that had completely detached from the back of the intermediate reinforcement layer or whose remaining adhesion area was less than 50% of the original silicone dot outline area were recorded as detached silicone dots. The number of detached silicone dots was divided by the initial number of silicone dots and multiplied by 100% to obtain the silicone dot detachment rate of a single square sample. The average value of the test results of five square samples was then taken as the silicone dot detachment rate of the sample. The reason for adopting the above test method is that by covering and encasing the exposed fiber segments with the anti-slip locking layer, the silicone dots not only adhere to the back of the intermediate reinforcement layer, but are also associated with the longitudinal fiber anchors. Therefore, calculating the silicone dot detachment rate by the retention state of the silicone dots after repeated friction can better reflect the locking stability of the anti-slip locking layer under actual dragging, sitting pressure and folding conditions.

[0030] The anti-slip retention rate after 20 washes indicates the degree to which the anti-slip locking layer of the finished floral felt anti-slip cooling mat maintains its original anti-slip ability after repeated washing. Specific testing is required. Square samples with a length of 100mm and a width of 100mm were cut from the finished anti-slip mat. The static friction coefficient before washing was measured according to the aforementioned test method. The square samples were then placed in a standard washing machine for 20 cycles of washing. Each wash was completed by washing with room temperature water, gently agitating, and air drying. After 20 cycles, the samples were left to stand for 2 hours in an environment of 23±2℃ and 50±5% relative humidity. The static friction coefficient after washing was measured again according to the same method. The static friction coefficient after washing was divided by the static friction coefficient before washing and then multiplied by 100% to obtain the anti-slip retention rate of a single square sample after 20 washes. The average value of the test results of five square samples was then taken as the anti-slip retention rate of the sample after 20 washes. The reason for using the above testing method is that the anti-slip effect depends not only on the frictional ability of the anti-slip locking layer surface, but also on the stability of the anti-slip locking layer in covering the exposed fiber segments. Therefore, using the change in the static friction coefficient before and after 20 washes to characterize the anti-slip retention is more able to reflect the actual anti-slip stability of the felt anti-slip cooling mat after daily washing, drying and repeated use.

[0031] The layer length after 50 folds is used to indicate the cumulative length of separation between the main layer, the middle reinforcement layer and the anti-slip locking layer of the finished floral felt anti-slip mat after repeated folding. This is measured during the specific test. Cut strip samples with a length of 300mm and a width of 100mm from the finished anti-slip mat. Fold the sample back and forth along the center line of its length 50 times. After that, unfold the sample naturally and lay it flat. Let it stand for 30 minutes in an environment of 23±2℃ and 50±5% relative humidity. Then observe whether there are visible separation areas between the main layer of the floral felt, the middle reinforcement layer and the anti-slip locking layer along the edge and middle of the sample. Measure the length of each separation area. Take the sum of the lengths of all separation areas of the same sample as the layer length of a single strip sample after 50 folds. Take the average value of the test results of five strip samples as the layer length of the sample after 50 folds. The reason for adopting the above test method is that the longitudinal fiber anchor, exposed fiber segment and anti-slip locking layer form a penetrating locking connection. Therefore, the interlayer stability is characterized by the interlayer separation length after repeated folding, which can better reflect the structural maintenance ability of the felt anti-slip cooling mat under daily storage, transportation and repeated bending conditions.

[0032] The laying displacement is used to indicate the distance that the finished anti-slip mat moves relative to its initial laying position under the action of external force after it is laid on the surface of the carrier. In specific testing; A 600mm long and 1200mm wide non-slip mat sample was laid flat on a smooth, lacquered wooden test bench. The initial position was set with one edge of the sample aligned with the baseline of the test bench. A 20kg vertical load was applied to the center of the sample and it was pushed back and forth 10 times along the length of the sample, with each push being 150mm. After the push was completed, the maximum offset distance of the sample edge relative to the initial baseline was measured and taken as the laying displacement of a single test. The average value of the results of three repeated tests was then taken as the laying displacement of the sample. The reason for adopting the above testing method is that the goal of anti-slip improvement is to reduce the degree of slippage of the floral anti-slip mat on common laying surfaces such as bed boards, sofa bases and bay window sills. Therefore, the actual offset distance after the application of external force is used to characterize the laying stability, which can better reflect the inhibitory effect of the anti-slip locking layer on daily sitting pressure, dragging and turning conditions.

[0033] In this embodiment, a 3.6mm thick felt main body layer is formed by mixing 38mm long, 21μm fine wool fibers with 51mm long, 1.5D fine recycled polyester fibers in a 6:4 ratio. A middle reinforcement layer of polyester nonwoven fabric with a surface density of 90g / ㎡ is formed by piercing the felt main body layer towards the middle reinforcement layer, creating longitudinal fiber anchors with an average exposed fiber length of approximately 0.7mm and a unit area of ​​approximately 115 anchors per 100cm². These anchors are then covered and encapsulated within the anti-slip locking layer using food-grade silicone drip molding with a 4mm dot spacing and 0.9mm dot height. Finally, a second hot-pressing process is performed at 110℃ and 0.25MPa. This process transforms the traditional method of using only surface adhesion to maintain the anti-slip layer on the back of the felt mat into a method where the felt itself forms the anchors. The penetrating locking connection method, consisting of a main layer, an intermediate reinforcing layer, longitudinal fiber anchors, exposed fiber segments, and an anti-slip locking layer, can more specifically solve the problems that easily occur in existing felt-like laying products during repeated sitting, lying down, turning over, dragging, folding and storing, and washing and drying. These problems include localized lifting of the anti-slip locking layer, detachment of silicone dots, loosening between layers, and misalignment of the laying position. In use, ordinary back-drip plastic structures often slip and curl at the corners where they are subjected to force. However, the longitudinal fiber anchors formed by the above preparation method can further transfer the force from the back of the intermediate reinforcing layer to the interior of the felt main layer. The anti-slip locking layer's coverage of the exposed fiber segments can also inhibit the shrinkage and detachment of the exposed fiber segments after dragging, friction, washing, and spin-drying. Therefore, it is more conducive to maintaining the stability of the anti-slip position, the flatness of the edges, the tightness of the interlayer adhesion, and the continuity of anti-slip after long-term use.

[0034] Example 2 Specifically: the mass ratio of the wool fiber to the regenerated fiber is 6:4; the thickness of the main layer of the felt after the first hot pressing and shaping is 3-4 mm.

[0035] Based on Example 1, this embodiment describes the raw material ratio, surface pattern, first hot pressing temperature, and thickness after the first hot pressing of the main body layer of the felt: Preferably, the mass ratio of wool fiber to recycled polyester fiber is fixed at 6:4, the pattern formed by die-stamping is an almond flower pattern, the first hot pressing and setting temperature is controlled at 130℃, and the thickness of the main body layer of the felt after the first hot pressing and setting is controlled at 3.6mm, so as to maintain the clarity of the surface pattern of the main body layer of the felt while ensuring that the internal fiber network of the main body layer of the felt has a stable state suitable for subsequent puncture and bonding.

[0036] During raw material preparation, wool fibers with a length of 38mm and a fineness of 21μm and recycled polyester fibers with a length of 51mm and a fineness of 1.5D are selected and weighed at a mass ratio of 6:4. After opening and mixing, the mixing time is controlled at 12 minutes. Then, the fibers are carded into a uniform fiber web and cross-laid to form an initial felt layer. The initial felt layer density is controlled at 780g / ㎡ and the initial thickness is controlled at 5.2mm. The reason for using the above mass ratio is that maintaining the wool fiber ratio at 60% can ensure the felting continuity after the felting is formed, and maintaining the recycled polyester fiber ratio at 40% can improve the dispersion uniformity and dimensional stability of the fiber network. This makes it easier to obtain a stable and consistent felt body layer in the subsequent die-stamping, needle punching, and first hot pressing processes.

[0037] The pattern formed by the stamping is either an almond flower pattern or a scroll pattern; the temperature of the first hot pressing is 120-140℃.

[0038] The initial felt layer is fed into a felting machine for reciprocating compaction. The felting pressure is controlled at 0.22 MPa, and the felting time is controlled at 9 minutes, so that the initial felt layer forms a continuous felt structure. Then, almond patterns are pressed onto the surface of the felt layer using a die-stamping method. The die-stamping pressure is controlled at 0.18 MPa, and the holding time is controlled at 8 seconds. The printed felt layer is then needle-punched and interwoven. The needle-punching density is controlled at 210 needles / cm², and the needle-punching depth is controlled at 6 mm. After the needle-punching and interwoven process is completed, the first hot-pressing and shaping is carried out at 130℃ for 35 seconds, resulting in a 3.6 mm thick felt body layer. The almond pattern is used to retain the decorative identification characteristics of the felt product. The first hot-pressing and shaping temperature of 130℃ is within the range of 120-140℃, which can further stabilize the internal fiber network of the felt body layer and avoid hardening of the surface pattern edges and local collapse due to excessive temperature.

[0039] The thickness of the main layer of the felt after the first hot pressing is controlled within the range of 3-4mm, preferably 3.6mm. The reason is that when the thickness of the main layer is less than 3mm, the amount of fiber stored inside the main layer that can be punctured to form longitudinal fiber anchors is insufficient. The number of exposed fiber segments that pass through the intermediate reinforcement layer and are exposed on the back of the intermediate reinforcement layer is also small, which is not conducive to the formation of a stable covering and locking relationship of the anti-slip locking layer. When the thickness of the main layer is greater than 4mm, the overall flexibility of the main layer decreases, the interlayer adhesion after the second hot pressing is prone to decrease, and the weight of the finished product will increase significantly. Therefore, limiting the thickness of the main layer of the felt to the range of 3-4mm is beneficial to balance the soft touch of the anti-slip mat, the stability of puncture bonding, and the subsequent anti-slip locking effect.

[0040] In this embodiment, by limiting the mass ratio of wool fiber to recycled polyester fiber to 6:4, and limiting the pattern formed by die-stamping to either almond flower or scroll pattern, while limiting the temperature of the first hot-pressing to 120-140℃ and the thickness of the felt body layer after the first hot-pressing to 3-4mm, the special benefits of these conditions are not mainly reflected in the connection method of the terminal anti-slip locking layer, but more specifically in the stable control of the forming quality of the front end of the felt body layer. That is, while ensuring the continuity of wool fiber felting, the recycled polyester fiber can be used to improve the dispersion uniformity and dimensional stability of the fiber network, so that the felt body layer has a relatively uniform thickness, a relatively clear almond flower or scroll pattern boundary, and a relatively stable thickness before entering the subsequent piercing and laminating process. The internal fiber support is fixed to reduce issues such as localized thinning, excessive hardness, blurred pattern edges, or discontinuous fiber pull-out during puncture in different locations during batch production. In actual continuous production, if the thickness of the main body layer of the felt is less than 3mm after the first hot pressing and shaping, the main body layer of the felt is prone to insufficient fiber pull-out during subsequent puncture and bonding, resulting in insufficient formation of longitudinal fiber anchors. If the thickness of the main body layer of the felt is greater than 4mm after the first hot pressing and shaping, the main body layer of the felt is prone to problems such as being too thick, too heavy, and having inconsistent local rebound when laid on beds, sofas, or folded and stored. The above conditions enable the main body layer of the felt to simultaneously maintain pattern retention, soft touch, thickness consistency, and adaptability to subsequent processes, making it more suitable for forming a semi-finished felt anti-slip cooling mat with stable appearance and less process fluctuation.

[0041] Example 3 Please see Figure 2 and Figure 3 Specifically: when the main body layer of the felt and the intermediate reinforcement layer are punctured and bonded, the puncture direction is from the main body layer of the felt to the intermediate reinforcement layer; the part of the longitudinal fiber anchor that passes through the back of the intermediate reinforcement layer is an exposed fiber segment, which can be covered and wrapped by the anti-slip locking layer.

[0042] The intermediate reinforcement layer is a non-woven fabric layer; the weight of the non-woven fabric layer is 80-100 g / m²; the non-woven fabric layer is laid flat on the back of the main body of the felt and serves as the penetrating support layer for the longitudinal fiber anchor.

[0043] The anti-slip locking layer is formed by dripping food-grade silicone into silicone dots, with a dot diameter of 2.0 mm, a dot spacing of 3-5 mm, and a height of 0.8-1.0 mm; the anti-slip locking layer is cured at room temperature for 24 hours.

[0044] Based on Example 1, this embodiment describes the puncture composite direction of the main layer and the intermediate reinforcing layer of the felt, the material form and weight of the intermediate reinforcing layer, the dripping parameters of the anti-slip locking layer, and the curing conditions: The puncture direction is set from the main layer of the felt to the middle reinforcement layer. The middle reinforcement layer is a non-woven fabric layer with a weight of 90g / ㎡. The anti-slip locking layer is formed by dripping food-grade silicone dots. The diameter of the silicone dots is controlled at 2.0mm, the dot spacing is controlled at 4mm, and the height is controlled at 0.9mm. The curing method is room temperature curing for 24 hours, so that the longitudinal fiber anchor can stably pass through the middle reinforcement layer and form an exposed fiber segment on the back of the middle reinforcement layer that can be covered and wrapped by the anti-slip locking layer. The reason for limiting the puncture direction to from the main layer of the felt to the intermediate reinforcing layer is that the main layer of the felt has a higher fiber content, better fiber continuity, and a stronger felting degree. When puncturing from the main layer of the felt to the intermediate reinforcing layer, it is easier to drive some of the fibers in the main layer of the felt to migrate outward and pass through the intermediate reinforcing layer, thus forming a larger number of evenly distributed longitudinal fiber anchors. However, if the puncture is performed from the intermediate reinforcing layer in the opposite direction to the main layer of the felt, it is easier to cause local disturbance to the intermediate reinforcing layer and insufficient fiber penetration from the main layer of the felt, which is not conducive to the stable formation of exposed fiber segments.

[0045] After the main body of the floral felt is prepared, the non-woven fabric layer is laid flat on the back of the main body of the floral felt. Then, a piercing device is used to pierce and composite the main body of the floral felt from one side to the middle reinforcement layer. The piercing density is controlled at 160 needles / cm² and the piercing depth is controlled at 4.5mm. This allows some fibers in the main body of the floral felt to pass through the non-woven fabric layer along the thickness direction under the piercing push, and form a continuous fiber bundle structure on the back of the non-woven fabric layer, thereby forming a longitudinal fiber anchor. Among them, the part of the longitudinal fiber anchor exposed on the back of the intermediate reinforcement layer is the exposed fiber segment. The average length of the exposed fiber segment is controlled within the range of 0.6-0.8mm to ensure that the subsequent dripping material can form a stable cover and coating on the exposed fiber segment.

[0046] The intermediate reinforcing layer is defined as a non-woven fabric layer, and the basis weight of the non-woven fabric layer is limited to the range of 80-100 g / m², preferably 90 g / m². This is because the non-woven fabric layer has good pore continuity, thickness uniformity, and fiber traction adaptability. During the piercing and bonding process, it can provide a penetration channel for the longitudinal fiber anchors and provide layer support for the longitudinal fiber anchors after penetration. Thus, the non-woven fabric layer not only represents the transition layer sandwiched between the main felt layer and the anti-slip locking layer, but also represents the penetration support layer for the longitudinal fiber anchors. When the basis weight of the non-woven fabric layer is less than 80 g / m², the support capacity is weak and local tearing is likely to occur during subsequent hot pressing and folding. When the basis weight of the non-woven fabric layer is greater than 100 g / m², the fiber resistance is too large, which is not conducive to the stable penetration of the longitudinal fiber anchors.

[0047] The anti-slip locking layer is limited to a silicone dot structure formed by dripping food-grade silicone because food-grade silicone has good flexibility, molding stability, and surface friction properties. After forming silicone dots, it can maintain adhesion to the back of the intermediate reinforcing layer and form a covering and locking effect on the exposed fiber segments after curing. Limiting the silicone dot diameter to 2.0mm, the dot spacing to 3-5mm, and the height to 0.8-1.0mm helps to balance coverage area, smooth touch, and anti-slip continuity. If the silicone dot diameter is too small, the coverage area of ​​the exposed fiber segments will be insufficient; if the silicone dot diameter is too large, it will easily increase the local hardness; if the dot spacing is too large, it will not be conducive to forming a continuous anti-slip area; if the dot spacing is too small, it will easily increase the amount of material used and affect the flatness of the back.

[0048] After drip molding, the composite is placed in an environment of 23°C and 50% relative humidity for 24 hours of room temperature curing. This allows for full cross-linking of the silicone dots and the formation of a stable connection between the silicone dots, the back of the intermediate reinforcing layer, and the exposed fiber segments. The reason for using room temperature curing for 24 hours is that it avoids the impact of the high-temperature curing stage on the existing structural relationship between the main layer of the felt, the intermediate reinforcing layer, and the exposed fiber segments. At the same time, it allows the silicone dots to gradually complete internal curing and maintain good flexibility, providing a stable foundation for subsequent second hot pressing and shaping, as well as repeated folding, dragging, and washing during the use of the finished product.

[0049] In this embodiment, the puncture direction is defined as from the main fabric layer to the intermediate reinforcing layer, and the intermediate reinforcing layer is defined as a non-woven fabric layer with a basis weight of 80-100 g / m². Simultaneously, the anti-slip locking layer is defined as a silicone dot structure formed by food-grade silicone dripping, with silicone dots having a diameter of 2.0 mm, a dot spacing of 3-5 mm, and a height of 0.8-1.0 mm. This structure is then cured at room temperature for 24 hours at 23°C and 50% relative humidity. The unique advantages of these conditions are mainly reflected in the stability of the longitudinal fiber anchors and exposed fiber segments, as well as the consistent distribution of the anti-slip locking units. Specifically, it allows some fibers in the main fabric layer to more easily penetrate the intermediate reinforcing layer along the predetermined direction, forming exposed fiber segments of suitable length for coverage and wrapping on the back of the intermediate reinforcing layer. Simultaneously, the non-woven fabric layer provides both sufficient penetration channels and continuous penetration support. Combined with food-grade silicone dripping... The formed silicone dots cover and lock the exposed fiber segments point by point, thus creating a more even and continuous distribution of anti-slip locking units on the back of the entire felt anti-slip mat, reducing the likelihood of gaps in the anti-slip locking units. In practical use, when the felt anti-slip mat is laid on a smooth surface such as a leather sofa, wooden bed board, or tile platform, where local stress changes rapidly, if the exposed fiber segments are discontinuous, the non-woven fabric layer is too thin, or the size and spacing of the silicone dots are mismatched, it is easy to have some areas of the back with anti-slip effect while others do not, or for some areas to loosen or curl up first. With the above-mentioned limiting conditions, it is more conducive to maintaining a nearly consistent back friction state and locking state in different stress areas of the felt anti-slip mat, thereby improving the uniformity of use, recovery after folding, and anti-slip continuity of the entire product in corners, turning areas, and frequently pressured areas.

[0050] Example 4 Please see Figure 2 and Figure 3 Specifically: the temperature of the second hot pressing is 100-120℃, the hot pressing pressure is 0.2-0.3MPa, and the hot pressing time is 30s; the second hot pressing is used to press the interlayer bonding area between the main layer of the felt, the intermediate reinforcing layer and the anti-slip locking layer.

[0051] The silicone dots are positioned corresponding to the exposed fiber segments on the back of the intermediate reinforcing layer; each silicone dot covers one or more exposed fiber segments to form multiple dispersed anti-slip locking units.

[0052] This embodiment, based on Embodiment 1, explains the temperature, pressure, and time of the second hot-pressing setting, as well as the positional correspondence between the silicone dots and the exposed fiber segments: The second hot-pressing process involves controlling the temperature at 110℃, the hot-pressing pressure at 0.25MPa, and the hot-pressing time at 30s. The silicone dots are positioned to correspond to the exposed fiber segments on the back of the intermediate reinforcement layer. This allows for further compression of the interlayer bonding area between the main felt layer, the intermediate reinforcement layer, and the anti-slip locking layer after the drip molding and curing process. Simultaneously, each silicone dot covers one or more exposed fiber segments, thus forming multiple dispersed anti-slip locking units.

[0053] After completing the preparation of the main layer of the felt, the laying of the intermediate reinforcement layer, the piercing composite to form longitudinal fiber anchors, and the drip curing, the composite is sent to a flat hot press for a second hot pressing and shaping. The surface temperature of the upper and lower pressure plates of the hot press is controlled at 110℃, the pressure of the pressure plates is controlled at 0.25MPa, and the holding time is controlled at 30s. This allows the cured anti-slip locking layer to further adhere to the back of the intermediate reinforcement layer under heat and pressure, and makes the exposed fiber segments more stably embedded in the anti-slip locking layer under pressure, thereby improving the overall tightness of the bond between the main layer of the felt, the intermediate reinforcement layer, and the anti-slip locking layer.

[0054] The second hot-pressing and setting temperature is limited to the range of 100-120℃, preferably controlled at 110℃. The reason is that when the second hot-pressing and setting temperature is below 100℃, the interface bonding effect between the anti-slip locking layer and the intermediate reinforcing layer is not obvious, and the embedded stability of the exposed fiber segments in the anti-slip locking layer is weak, which is not conducive to forming a tighter locking relationship. When the second hot-pressing and setting temperature is above 120℃, the cured anti-slip locking layer is prone to problems such as excessively soft surface, local deformation, or blunting of silicone dot contours, which in turn affects the integrity of the dotted anti-slip structure on the back. Therefore, limiting the second hot-pressing and setting temperature to the range of 100-120℃ is more conducive to balancing the interlayer pressing effect and the shape maintenance effect of the anti-slip locking layer.

[0055] The second hot-pressing setting pressure is limited to the range of 0.2-0.3 MPa, preferably controlled at 0.25 MPa. The reason is that when the hot-pressing pressure is lower than 0.2 MPa, the interlayer bonding area is not sufficiently compressed, and the interface between the anti-slip locking layer and the intermediate reinforcing layer is difficult to tighten further. The exposed fiber segments are also not easy to form a more stable embedded relationship under pressure. When the hot-pressing pressure is higher than 0.3 MPa, the silicone dots in the anti-slip locking layer are prone to local flattening, edge widening, or excessive height reduction, thereby weakening the friction effect of the dotted anti-slip structure on the back. Therefore, limiting the hot-pressing pressure to the range of 0.2-0.3 MPa is more conducive to maintaining the structural integrity and locking stability of the anti-slip locking layer.

[0056] The second hot-pressing setting time is limited to 30 seconds because 30 seconds is sufficient for heat and pressure to be effectively transferred between the main layer of the felt, the intermediate reinforcing layer and the anti-slip locking layer, thereby further pressing the interlayer bonding area. At the same time, it can avoid the problem of excessive leveling of the anti-slip locking layer or blurring of the dotted outline boundary caused by excessive hot pressing time. Therefore, a hot pressing time of 30 seconds is more conducive to maintaining the original dispersed anti-slip structure of the silicone dots while pressing the interlayer bonding area.

[0057] The distribution positions of the silicone dots and exposed fiber segments on the back of the intermediate reinforcing layer are set in a corresponding manner. Specifically, before drip molding, the distribution area of ​​the exposed fiber segments on the back of the intermediate reinforcing layer is recorded. Then, the arrangement of the drip molding dots is matched with the recorded distribution area, so that each silicone dot covers one or more exposed fiber segments after molding. This results in multiple silicone dots forming a local covering relationship with multiple exposed fiber segments, thereby forming multiple dispersed anti-slip locking units. Among them, the anti-slip locking unit is no longer just an ordinary back friction unit; the anti-slip locking unit also refers to a structural unit that locally locks the exposed fiber segments.

[0058] The reason for setting the silicone dots and exposed fiber segments in a positional correspondence is that if the distribution of silicone dots deviates from the distribution of exposed fiber segments, some silicone dots may only be attached to the back of the intermediate reinforcement layer without effectively covering the exposed fiber segments, or some exposed fiber segments may be exposed without being covered by silicone dots. Such situations will weaken the locking effect of the anti-slip locking layer on the longitudinal fiber anchor. By setting the positional correspondence so that each silicone dot covers at least one exposed fiber segment, the anti-slip locking layer can be transformed from a simple surface attachment structure into a covering and locking structure associated with the longitudinal fiber anchor.

[0059] In this embodiment, by limiting the temperature of the second hot-pressing to 100-120℃, the hot-pressing pressure to 0.2-0.3MPa, and the hot-pressing time to 30s, and by correspondingly setting the distribution positions of the silicone dots and exposed fiber segments on the back of the intermediate reinforcing layer, the special advantages formed by the above conditions are mainly reflected in the later-stage shaping accuracy and long-term service stability of the anti-slip locking unit. That is, after the drip molding curing is completed, the second hot-pressing not only further tightens the interlayer bonding area between the main layer of the felt, the intermediate reinforcing layer, and the anti-slip locking layer, but also allows the exposed fiber segments to be more stably embedded in the anti-slip locking layer under heat and pressure conditions. At the same time, it avoids the problems of local flattening, edge widening, contour blunting, or position drift of the silicone dots due to reheating. Combined with the corresponding setting method of silicone dots and exposed fiber segments, each anti-slip locking unit can simultaneously bear the load. It combines back friction and local locking, making it more suitable for solving problems that easily occur in existing felt-like floor coverings after long-term use, such as localized loosening of locking, instability of corner stress areas, and asynchronous attenuation of anti-slip effect after wear of the back dotted structure. When the felt anti-slip mat is continuously laid at the foot of the bed, the corner of the sofa, or the bay window sill that is frequently dragged back and forth, if the second heat pressing is insufficient or the silicone dots are not set to correspond with the exposed fiber segments, the silicone dots in some areas will still exist but will no longer be able to effectively hold the exposed fiber segments, causing slight arching or slippage in those areas. With the above-mentioned limiting conditions, it is more conducive to ensuring that the anti-slip locking unit maintains a clear outline, stable embedding, and synchronized force during repeated cycles of sitting, folding, storage, washing, and drying. This improves the edge and corner conformity, regional anti-slip synchronization, and overall dimensional retention of the felt anti-slip mat under long-term use.
