Description

Technical Field

[0001] This utility model relates to the field of carpets, and more particularly to a loop pile tufted carpet with UV protection. Background Technology

[0002] During use, especially in summer, cars are exposed to high-intensity ultraviolet radiation. Most car carpets are tufted carpets, which have many advantages, including elasticity, dimensional stability, and rich colors and patterns. However, under long-term exposure to ultraviolet radiation, the yarns on the surface of tufted carpets will age, usually manifested as color fading, reduced strength, and brittleness.

[0003] CN2270507Y discloses an ultraviolet carpet sterilizer, a vehicle-shaped sterilizer consisting of a power supply, ultraviolet lamps, a base plate, a shell, a grid brush, wheels, and a handle. The base plate of the vehicle-shaped sterilizer has a power supply, a light source board, and a printed circuit board. The front end of the base plate has a grid brush. The light source board is fixed to the base plate in a cover shape. The area of ​​the base plate covered by the light source board is directly transparent to the ground. The light source board has 2-4 ultraviolet lamps, which are 15-25cm away from the ground. The front end of the base plate has directional wheels, and the rear end has guide wheels. The shell covers the base plate and is fitted and fixed to the base plate. The shell has multiple handle sections. The carpet sterilizer constructed in this way has a high sterilization rate, but this solution cannot solve the problem of carpet aging under long-term ultraviolet radiation.

[0004] CN220808803U discloses a UV-resistant multi-component high colorfastness carpet, comprising a carpet body with a carpet edge banding sewn onto its outer edges. The carpet body is specifically composed of an insulating backing, a colored layer, a water-repellent protective layer, and an abrasion-resistant pile surface. The colored layer is connected to one side of the insulating backing, the water-repellent protective layer to the other side, and the abrasion-resistant pile surface to the other side. This method, by setting an insulating backing, can isolate and protect the high colorfastness carpet from the ground, preventing moisture and dust from penetrating the colored layer through the insulating backing. It also ensures the comfort of using the high colorfastness carpet. It provides UV protection to the colored layer and prevents the water channels from breaking due to the folding and rolling of the water-repellent backing, thus guaranteeing the protective performance of the high colorfastness carpet. Although this carpet can block some UV rays, it requires an additional multi-layered structure, thus increasing the manufacturing cost and difficulty of the carpet.

[0005] CN216507125U discloses a composite needle-punched nonwoven fabric for automotive interior carpets, comprising a nonwoven fabric, which includes a nonwoven fabric bottom layer located below. A sound-absorbing felt layer is bonded to the top side surface of the nonwoven fabric bottom layer, a heat-insulating layer is bonded to the top side surface of the sound-absorbing felt layer, a fiber layer is bonded to the top side surface of the heat-insulating layer, a water-absorbing layer is bonded to the top side surface of the fiber layer, and an abrasion-resistant layer is bonded to the top side surface of the water-absorbing layer. Multiple abrasion-resistant protrusions are fixedly provided on the top side surface of the abrasion-resistant layer. Although this design can enable the nonwoven fabric to have the functions of sound insulation, heat insulation, water absorption, abrasion resistance, antibacterial and UV resistance, the overall structure is also complex, which increases the manufacturing cost and difficulty of the carpet.

[0023] Beneficial effects of this utility model

[0024] Nowadays, most car carpets are tufted carpets. Tufted carpets have many obvious advantages, including elasticity, strong dimensional stability, and rich colors and patterns. However, the yarns on the surface of tufted carpets will age under long-term exposure to ultraviolet rays, which usually manifests as color fading, reduced strength, and brittleness.

The UV-resistant yarn layer is located at the very top of the carpet, enhancing its UV protection and aesthetics. The backing felt layer is located at the very bottom. The non-woven fabric layer is located between the UV-resistant yarn layer and the backing felt layer, and is situated at the bottom of the UV-resistant yarn layer. The coating layer is located between the non-woven fabric layer and the backing felt layer, and is situated at the top of the backing felt layer. The adhesive layer is located at the top of the coating layer and the bottom of the non-woven fabric layer. This invention unexpectedly embeds UV absorbers into the yarn (absorbing UV rays), increases the yarn twist, and uses a double-row needle tufting device (distributing the loop pile in an irregular pattern), thereby giving the carpet UV protection properties, delaying aging, and enhancing its aesthetic appeal.

[0035] Figure 1This is a structural schematic diagram of a loop pile anti-UV tufted carpet according to the present invention. The carpet includes an anti-UV yarn layer 1, a backing felt layer 2, a non-woven fabric layer 3, a coating layer 4, and an adhesive layer 5. The anti-UV yarn layer 1 is located entirely at the top of the carpet and is used to enhance the carpet's anti-UV performance by embedding UV absorbers within the yarns. Furthermore, the loop pile of the yarn layer is irregularly distributed, giving the carpet an aesthetic appeal. The backing felt layer 2 is located entirely at the bottom of the carpet. The base layer 2 serves as the skeleton of the carpet, supporting it and providing a certain degree of rigidity. The non-woven fabric layer 3 is located entirely between the UV-resistant yarn layer 1 and the base layer 2, with the non-woven fabric layer 3 situated at the bottom of the UV-resistant yarn layer 1. The non-woven fabric layer 3 acts as the substrate for the yarn weaving, serving as both a reinforcing layer and an insulating layer. The coating layer 4 is located entirely between the non-woven fabric layer 3 and the base layer 2, with the coating layer 4 situated on top of the base layer 2. The coating layer 4 is used to bond the base layer 2. The adhesive layer 5 is located entirely on top of the coating layer 4 and at the bottom of the non-woven fabric layer 3. The adhesive layer 5 is used to fix the non-woven fabric layer 3.

[0036] Optionally, the UV-resistant yarn layer 1 includes yarn and a UV absorber.

[0037] Ultraviolet absorbers can effectively absorb ultraviolet light and have good thermal stability. They can convert high-energy ultraviolet light energy into heat energy or release longer light waves without causing damage.

[0038] Optionally, the UV absorber is embedded inside the yarn and evenly distributed, and the UV absorber is used to enhance the carpet's UV resistance.

[0039] By adding UV absorber masterbatch to the raw material masterbatch, yarn with UV protection function can be produced.

[0040] Optionally, the amount of ultraviolet absorber used is 0.15-0.25% of the yarn mass.

[0041] The amount of UV absorber used must be kept within a reasonable range. If it is too little, the ideal UV protection effect cannot be achieved. However, once the critical point is reached, even if the amount of UV absorber is increased, the UV protection performance of the carpet cannot be further enhanced.

[0042] Optionally, the yarn twist is 270-290S.

[0043] Normally, the twist of yarn is around 160S (160 twists / 1000mm). After tufting, the angle between the loops of the two yarns is ≤60°, and the loops are distributed in a regular manner, which is not novel or beautiful. However, this utility model increases the twist of the yarn to make the yarn tight enough, so that the loops are distributed in an irregular state, which is both novel and beautiful.

[0044] Optionally, the loop pile of the UV-resistant yarn layer 1 is distributed in an irregular manner.

[0045] In addition to increasing the yarn twist mentioned above, a 1 / 6+1 / 6 double-row needle tufting device (usually a 1 / 10 single needle) can be used to tuft the yarn in a "Z" pattern (usually a straight line) to make the direction of advance irregular and further enhance the irregular distribution of loop pile.

[0046] Optionally, the material of the base felt layer 2 is polyethylene terephthalate.

[0047] Polyethylene terephthalate (PET) has good strength, abrasion resistance, and durability, making it suitable as a carpet skeleton for supporting the carpet.

[0048] Optionally, the coating layer 4 is made of polyethylene, and the melting point of the coating layer 4 is 105-135℃.

[0049] The coating layer 4 is made of low-density polyethylene with a melting point of 105-135℃.

[0050] Optionally, the adhesive layer 5 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 3 well.

[0052] Optionally, the solid content of adhesive layer 5 is 45-48%.

[0053] Only when the solid content is kept within a reasonable range can the adhesive layer 5 have sufficient bonding strength.

[0054] 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.
