Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-skid carpets, in particular to an anti-skid carpet for vehicles. Background Art
[0002] Most anti-slip carpets used in cars are tufted. Tufted carpets are machine-made carpets with a loop or cut pile surface, mechanically tufted using needles on a chemical fiber fabric backing. Anti-slip carpets for cars typically have an additional anti-slip layer at the bottom, while conventional anti-slip carpets typically have barbs or anti-slip rubber particles on the underside of the anti-slip layer to enhance friction. However, because conventional anti-slip carpets utilize pre-woven mesh barbs placed directly on the outer surface of the anti-slip layer and then needle-punched into it, the barbs are typically made of nylon plastic thread. This can lead to the barbs easily peeling from the anti-slip layer after repeated handling. The anti-slip rubber particles are typically glued to the bottom of the anti-slip layer, but this glue easily oxidizes, causing the anti-slip particles to fall off. This, in turn, can cause the anti-slip carpet to lose its anti-slip properties and move, compromising driving safety. Utility Model Content

DETAILED DESCRIPTION
[0024] To deepen the understanding of the present invention, the present invention will be further described below in conjunction with implementation examples and accompanying drawings. The present invention can be implemented in the following ways:
[0025] Example 1
[0026] Reference Figure 1-3 The anti-skid carpet for a vehicle of this embodiment includes a tufted carpet layer 1, a laminated adhesive layer 2 and an anti-skid base fabric layer 3 arranged in sequence from top to bottom.
[0027] The anti-slip base fabric layer 3 includes a non-woven fabric layer 31 and a warp and weft barb group 32 embedded in the non-woven fabric layer 31. The warp and weft barb group 32 includes a plurality of parallel weft threads 321 and a plurality of warp barb threads 322 perpendicular to the weft threads 321. The anti-slip barbs 3221 of the warp barb threads 322 protrude outside the anti-slip layer. In this embodiment, the weft threads 321 and the warp barb threads 322 are crisscrossed to form a grid. The warp barb threads 322 are woven into the non-woven fabric layer 31 and secured to the non-woven fabric layer 31 using the weft threads 321 crisscrossed with the warp barb threads 322. This not only improves the peel strength between the warp and weft barb group 32 and the non-woven fabric layer 31, but also effectively prevents deformation of the warp barb threads 322 after weaving.
[0028] In this embodiment, the barbed warp threads 322 include braided warp threads 3222 and barbed wire strands 3223 tucked onto the braided warp threads 3222. The braided warp threads 3222 are directly woven into the non-woven fabric layer 31. During the weaving process, the barbed wire strands 3223 are tucked onto the braided warp threads 3222 in a V-shape. The anti-slip barbs 3221 are positioned at the free ends of the barbed wire strands 3223. The outer end surfaces of the anti-slip barbs 3221 are rounded to prevent scratching. This design allows the braided warp threads 3222 to firmly embed the barbed wire strands 3223 within the non-woven fabric layer 31, significantly improving its peel strength.
[0029] To enhance the anti-slip properties of the barbed wire 3223, the barbed wire 3223 is extruded from nylon, PET, or PP. In this embodiment, the barbed wire 3223 is comprised of 1-4 strands of nylon. In this embodiment, the barbed wire 3223 is comprised of 3 strands of nylon. This design allows the barbed wire 3223 to be evenly distributed throughout the barbed warp threads 322 in a claw-like shape, further enhancing its anti-slip properties.
[0030] In this embodiment, the laminated adhesive layer 2 is a PE or TPR laminated adhesive layer. The laminated adhesive layer 2 and the tufted carpet layer 1 are laminated together without the use of adhesives, making them environmentally friendly. Furthermore, the laminated adhesive layer 2 provides a waterproofing effect.
[0031] In this embodiment, the tufted carpet layer 1 includes a base fabric layer 12 and a pile layer 11 tufted on the base fabric layer 12. The base fabric layer 12 is adjacent to the laminated adhesive layer 2. The pile layer 11 is made of PP, PET, PA long-staple bulked fiber, twisted and plied fiber, or wool twisted yarn. Other materials may also be used as needed.
[0032] Reference Figure 4 The production process of the above-mentioned anti-skid carpet for automobiles includes the preparation of the anti-skid base fabric, the preparation of the tufting layer and the lamination. By adopting this process, the above-mentioned carpet can be produced, and the peel strength of the anti-skid base fabric layer 3 can be improved.
[0033] In this embodiment, at least the following steps are included:
[0034] S1. Preparation of anti-slip base fabric: Weaving warp and weft barb groups 32 on the formed non-woven fabric, specifically including:
[0035] S11, preparation of non-woven fabric layer 31: Non-woven fabric fibers of different colors are mixed evenly, and then combed, web-combed, and stacked to form a non-woven base fabric, which is directly sent to the next process or rolled up for standby use. Specifically, the short fibers are first mechanically stirred and mixed using a fiber mechanical mixer 001, and then further mixed and evened using a fiber air-blowing mixer 002. Non-woven staple fibers are used because they have better drafting properties and are relatively low in cost. In addition, the rough and raised surface can increase the contact area between the non-woven fabric surface and the laminated adhesive layer 2, making subsequent interlocking with the laminated adhesive layer 2 easier and more secure. After the non-woven staple fibers of different colors are evenly mixed, they enter the carding machine 003 for carding, and then the carding net forms a thin layer of mesh fibers, which is then stacked layer by layer by the web laying machine 004 to the required thickness. The thickness of this embodiment is 400g / square meter. Finally, the needle loom 005 is used to form a solid non-woven fabric layer 31, which can directly enter the next process or be wound up by the first winding device 022 for standby use.
[0036] S12, weaving of the warp and weft barbed group 32: first, heat press one side of the non-woven base fabric. The upper surface of the non-woven base fabric after heat pressing is relatively flat, which is conducive to the subsequent weaving operation. Then, use the atomizer 003 to atomize and remove static electricity. Then, lay the weft 321 on the surface of the non-woven base fabric after heat pressing. Then, drop the warp so that the warp and weft 321 are perpendicular. The warp and weft 321 are staggered to prevent the warp from deforming after weaving. Use the sewing machine 008 to weave the warp onto the non-woven fabric to form the above-mentioned woven warp 3222. While weaving, use the needle punching mechanism of the sewing machine 008 to draw the wire cluster onto the warp to form anti-slip rings. At this time, a row of circular anti-slip rings will be formed on the woven warp 3222. This process can weave the weft 321, the barbed warp 322 and the non-woven fabric layer 31 into one, greatly improving the peel strength between the warp and weft barbed group 32 and the non-woven fabric layer 31. In addition, the wire drawing wire of this embodiment is made by extruding and drawing nylon material, and has strong anti-slip ability.
[0037] S13, after weaving is completed, it is subjected to high temperature setting by the drying device 009, and then the anti-slip ring on the warp is cut by the shearing machine 010, so that the outer end surface of the warp forms a barb fork; because the barb fork will prick the hand, the safety is low. In order to solve the problem of the barb fork pricking the hand, the flame spray gun device 011 is used to burn the outer end surface of the barb fork to form the anti-slip barb 3221 (such as Figure 3 The anti-slip base fabric can be wound up by the second winding device 012 for later use or directly transferred to the next process. The anti-slip barbs 3221 can hook onto the vehicle interior trim, achieving a secure and anti-slip effect. During the burning process, the flame tail from the flame spray gun sweeps across the surface of the barb fork, causing the outer end surface of the anti-slip barb 3221 to shrink into a smooth surface, thus eliminating the problem of irritation.
[0038] S2. Preparation of tufted layer: First, a base fabric is woven by a weaving machine 013, and then tufted on the base fabric by a tufting machine 014 to form a tufted carpet. The tufted carpet can be wound up by a third winding device 015 for standby use or directly enter the next process.
[0039] S3. Laminating: The laminating machine's extruder 018 heats and extrudes a laminating adhesive layer 2. The extrusion material can be PE or TPR. The two sides of the laminating adhesive layer 2 are laminated and calendered with the anti-slip base fabric and tufted carpet, respectively. The non-slip base fabric with anti-slip burrs faces outward, while the pile side of the tufted carpet faces outward. After cooling, the laminating process is rolled up to form the automotive anti-slip carpet. This laminating process eliminates the need for adhesives and is environmentally friendly.
[0040] Reference Figure 4 The above production process requires the following equipment groups, including the anti-slip base fabric production part, the tufting part and the laminating part;
[0041] The production process for the non-slip base fabric includes, in chronological order, a fiber mechanical mixer 001, a fiber air-blowing mixer 002, a carding machine 003, a web laying machine 004, a needle loom 005, a hot press 006, an atomizer 007, a hemming machine 008, a drying device 009, a shearing machine 010, a flame spray gun 011, and a second reeling device 012. A first reeling device 022 can also be installed behind the needle loom 005 to reel in non-woven base fabric that cannot be woven immediately. The hemming machine 008 weaves the barbed warp threads 322 and weft threads 321 onto the non-woven fabric layer 31, thereby forming the warp and weft barb groups 32. The fiber network structure of the non-woven staple fibers is firmly bonded to the woven structure of the warp and weft barb groups 32 to enhance the peel strength of the non-slip automotive carpet. Furthermore, the flame spray gun 011 uses natural gas as fuel. When a combustion failure occurs, the pressure roller originally used to press the anti-skid base cloth down to the tail of the flame will bounce up, so that the anti-skid base cloth will immediately move away from the flame spray gun device 011, which can reduce the probability of safety accidents.
[0042] The tufting part includes a weaving machine 013, a tufting machine 014, and a third winding device 015 in the order of production. The weaving machine 013 is used to weave the base fabric, and then the tufting machine 014 is used to tuft the base fabric to form a tufted carpet.
[0043] Reference Figure 5 The laminating section primarily consists of a laminating machine, which, in order of production sequence, includes a non-slip base fabric unwinding device 016, a tufted carpet unwinding device 017, an extrusion device 018, a composite calendering device 019, a cooling device 020, and a fourth rewinding device 021. The laminating equipment used is all conventional and, to maintain the principle of economy in the review process, will not be detailed in this embodiment.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
