Description

Technical Field

[0001] This utility model relates to the field of carpets, and more particularly to a low-gloss nylon tufted car carpet. Background Technology

[0002] Nylon is a man-made fiber with excellent properties such as high strength, abrasion resistance, and resilience. In automotive carpets, nylon tufted carpets are highly favored for their durability and comfort. However, the surface of nylon fibers is relatively smooth and has a high gloss, making it easy for light to reflect off the carpet. Furthermore, the arrangement and density of the nylon fibers can also affect the reflective effect. If the fibers are neatly arranged and densely packed, the reflected light will be more concentrated, thus enhancing the reflective effect. In addition, nylon tufted carpets may undergo a series of processing steps during production, such as dyeing, embossing, and printing. These processes can affect the gloss and reflective properties of the carpet surface. For example, if the dyes used in the dyeing process are bright and have high colorfastness, the reflected light will be brighter and longer-lasting. Furthermore, processes such as embossing and printing may alter the microstructure of the fiber surface, making it smoother or creating specific patterns, thereby enhancing the reflective effect. Regardless of the cause, increased carpet reflectivity can cause glare for users, reducing their comfort and, in severe cases, interfering with the driver's vision and posing a safety hazard.

[0003] US20060076715A1 discloses a method for creating a low-gloss surface finish on a vehicle trim component by moving an energy beam and the trim component relative to each other; and treating the surface of the trim component with an energy beam during the relative movement of the energy beam and the trim component, the energy beam effectively reducing the gloss of the surface, but this method cannot be used to reduce the gloss of automotive carpets.

[0004] CN118721917A discloses a low-gloss matte transfer film and its preparation method, comprising an upper surface layer, a core layer, and a lower surface layer. The upper surface layer comprises the following raw materials in parts by weight: 30-40 parts polypropylene, 10-20 parts modified polyethylene, 2-5 parts matting agent, and 0.05-0.2 parts antioxidant. The core layer comprises the following raw materials in parts by weight: 80-90 parts polyolefin, 1-2 parts antistatic agent, and 1-2 parts slip agent. The lower surface layer comprises the following raw materials in parts by weight: 40-60 parts polypropylene and 1-5 parts silica. Although the matte transfer film provided by this method has excellent tensile strength, peel strength, and low gloss, this method cannot be used for the preparation of low-gloss nylon tufted automotive carpets.

[0005] CN118420994A discloses a low-gloss polyethylene material and its preparation method. This low-gloss polyethylene material is prepared from 45-75 parts by weight of polyethylene, 15-25 parts by weight of cross-linked polyvinyl chloride, 5-15 parts by weight of vinyl chloride-vinyl acetate copolymer, 5-15 parts by weight of ethylene-vinyl acetate copolymer, and 0.8 parts by weight of processing aids. By adding cross-linked polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, and ethylene-vinyl acetate copolymer to the polyethylene system, the gloss of the polyethylene material is reduced. However, this method cannot be used to prepare low-gloss nylon tufted automotive carpets.

[0006] CN207845887U discloses a novel low-elasticity segmented colored yarn, comprising natural-colored fibers and colored fibers. The natural-colored fibers are neatly arranged in a ring, and the colored fibers are spirally wound around the natural-colored fibers. The colored and natural-colored fibers float and interweave with each other. A cavity is formed in the middle of the ring-shaped yarn composed of natural-colored and colored fibers, and the cavity is filled with flame-retardant fibers. The interweaving method makes the segmented colored yarn structure more stable, with low elasticity, high gloss and abrasion resistance. At the same time, the flame-retardant filling ensures the safety of the segmented colored yarn in use and has a wide range of applications. However, this interweaving method will increase the gloss of the yarn, which is contrary to the technical effect of reducing the gloss of the yarn expected by this utility model.

[0024] Beneficial effects of this utility model

[0025] Nylon tufted car carpets typically have a smooth surface and high gloss, making them prone to light reflection. If the fibers are neatly arranged and densely packed, the reflected light is more concentrated, further enhancing the reflective effect. However, during the carpet's processing, such as dyeing, embossing, and printing, these processes can affect the carpet's surface gloss and reflective properties, potentially reducing the user experience and driving safety. This invention provides a low-gloss nylon tufted car carpet. The carpet includes a low-gloss yarn layer, a non-woven fabric layer, an adhesive layer, a coating layer, and a backing felt layer. The low-gloss yarn layer is located entirely on top of the non-woven fabric layer and is used to reduce the gloss of the carpet. The non-woven fabric layer is located entirely on top of the adhesive layer and below the low-gloss yarn layer. The adhesive layer is located entirely on top of the coating layer and below the non-woven fabric layer. The coating layer is located entirely on top of the backing felt layer and below the adhesive layer. The backing felt layer is located entirely at the bottom of the coating layer. This invention reduces the gloss of the nylon tufted car carpet by embedding a matting agent inside the yarn and increasing the MR value (yarn outer diameter R2 / inner diameter R1), i.e., increasing the diffuse reflection of the yarn. Furthermore, before the carpet enters the coating line, it passes through a water tank rich in multi-electrode ions to clean the oil from the carpet surface, thereby improving the user experience and driving safety.

[0031] This utility model provides a low-gloss nylon tufted car carpet, comprising a low-gloss yarn layer 1, a non-woven fabric layer 2, an adhesive layer 3, a coating layer 4, and a base felt layer 5, wherein...

[0032] The low-gloss yarn layer 1 is located on top of the non-woven fabric layer 2. The low-gloss yarn layer 1 is used to reduce the gloss of the carpet and show the color and pattern of the carpet.

[0033] The non-woven fabric layer 2 is located on top of the adhesive layer 3 and at the bottom of the low-gloss yarn layer 1. The non-woven fabric layer 2 is used as a substrate for yarn shuttle.

[0034] The adhesive layer 3 is located on top of the coating layer 4 and at the bottom of the non-woven fabric layer 2. The adhesive layer 3 is used to fix the non-woven fabric layer 2.

[0035] The coating layer 4 is located on top of the base felt layer 5 and at the bottom of the adhesive layer 3. The coating layer 4 is used to bond the base felt layer 5.

[0036] The base layer 5 is located at the bottom of the coating layer 4. The base layer 5 serves as the skeleton of the carpet and is used to support the carpet.

[0037] Figure 1This is a schematic diagram of the structure of a low-gloss nylon tufted car carpet according to this utility model. The carpet includes a low-gloss yarn layer 1, a non-woven fabric layer 2, an adhesive layer 3, a coating layer 4, and a backing felt layer 5. The low-gloss yarn layer 1 is entirely located on top of the non-woven fabric layer 2. The low-gloss yarn layer 1 is used to reduce the gloss of the carpet, for example, by embedding a matting agent inside the yarn and increasing the MR value (yarn outer diameter R2 / inner diameter R1). Furthermore, the yarn layer can also display the color and pattern of the carpet. To enhance aesthetics, the non-woven fabric layer 2 is situated on top of the adhesive layer 3 and at the bottom of the low-gloss yarn layer 1. As the substrate for yarn movement, the non-woven fabric layer 2 serves as both a reinforcing and insulating layer. The adhesive layer 3 is situated on top of the lamination layer 4 and at the bottom of the non-woven fabric layer 2, and is used to secure the non-woven fabric layer 2. The lamination layer 4 is situated on top of the base felt layer 5 and at the bottom of the adhesive layer 3, and is used to bond the base felt layer 5. The base felt layer 5 is situated at the bottom of the lamination layer 4, and as the carpet's skeleton, it supports the carpet and provides a certain degree of rigidity.

[0038] Optionally, the low-gloss yarn layer 1 includes yarn and a matting agent.

[0039] The low-gloss yarn layer 1 includes yarn and a matting agent, which reduces the gloss of the yarn.

[0040] Optionally, the matting agent is embedded inside the yarn and evenly distributed; the matting agent is used to reduce the gloss of the carpet.

[0041] By embedding matting agents into the interior of the yarn, the microstructure of the yarn can be altered, causing light to diffusely reflect rather than specularly reflect on the yarn surface, thereby reducing the gloss of the carpet.

[0042] Optionally, the matting agent is titanium dioxide, and the amount of titanium dioxide used is 0.5-0.7% of the yarn mass.

[0043] The amount of matting agent used must be kept within a reasonable range. If too little is used, the desired low gloss effect cannot be achieved; if too much is used, it will damage the yarn structure and reduce the yarn's abrasion resistance.

[0044] Optionally, the matting agent is titanium dioxide.

[0045] Titanium dioxide has a strong light scattering ability. When titanium dioxide particles are exposed to light, they cause the light path to disperse, weaken the color intensity, and thus eliminate or reduce the color effect of the pigment, making the carpet appear low-gloss.

[0046] Optionally, the yarn shape can be trilobal.

[0047] The yarn has a trilobal cross-section, which gives it a high coefficient of friction and a unique surface morphology, helping to increase the mechanical bulkiness of the carpet and reduce its gloss.

[0048] Optionally, the inner diameter of the yarn is R1, the outer diameter of the yarn is R2, and the ratio of R2 to R1 is denoted as MR, with a value of MR of 2.2-2.5.

[0049] like Figure 2 As shown, by increasing the outer diameter R2 (lateral area) and / or decreasing the inner diameter R1 (cylindrical area), the MR value can be increased, that is, the diffuse reflectance of the yarn can be improved. However, the inner diameter R1 cannot be too small, otherwise the abrasion resistance of the yarn will be reduced. Therefore, only when the MR value is kept within a reasonable range can the strength of the yarn itself be guaranteed and the diffuse reflectance of the yarn be improved.

[0050] Optionally, the adhesive layer 3 may be made of ethylene vinyl acetate or acrylic acid.

[0051] Ethylene vinyl acetate has good adhesion, elasticity and environmental friendliness; acrylic acid has good environmental friendliness, adhesion and weather resistance. Both materials can be used to fix the nonwoven fabric layer 2 well.

[0052] Optionally, the solid content of adhesive layer 3 is 45-48%.

[0053] Only when the solid content is kept within a reasonable range can the adhesive layer 3 have sufficient bonding strength.

[0054] Optionally, the coating layer 4 is made of polyethylene, and the melting point of the coating layer 4 is 105-135℃.

[0055] The coating layer 4 is made of low-density polyethylene with a melting point of 105-135℃.

[0056] Optionally, the material of the base felt layer 5 is polyethylene terephthalate.

[0057] Polyethylene terephthalate (PET) has good strength, abrasion resistance, and durability, making it suitable as a carpet skeleton for supporting the carpet.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
