Description

Technical Field

[0001] This utility model relates to a sofa fabric, specifically a tear-resistant and abrasion-resistant sofa fabric. Background Technology

[0002] Sofas are a common piece of furniture in homes, and people frequently sit, lie, and lean on them during daily use. Children may also play on them, and pets may move around on them. This makes sofa fabrics susceptible to various forms of friction, stretching, and tearing. Ordinary fabrics cannot withstand these external forces and are prone to wear, pilling, and tearing, affecting the sofa's appearance and lifespan. Therefore, consumers have a strong demand for sofa fabrics with tear resistance and abrasion resistance.

[0003] As living standards improve, people's demands for furniture quality are also increasing. Consumers not only pay attention to the style and comfort of sofas, but also increasingly value the durability of sofa fabrics. They hope to buy sofas that are durable and reduce the frequency of replacement, thereby saving costs and improving their quality of life. Therefore, it is necessary to provide a tear-resistant and abrasion-resistant sofa fabric. Utility Model Content

[0004] The purpose of this invention is to provide a tear-resistant and abrasion-resistant sofa fabric, which is designed to have better tear resistance and abrasion resistance than ordinary fabrics, thus extending its service life.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a tear-resistant and wear-resistant sofa fabric, comprising: a tear-resistant layer, wear-resistant layers laminated on both sides of the tear-resistant layer, and a TPU film laminated between the tear-resistant layer and the wear-resistant layer, wherein the wear-resistant layer, the tear-resistant layer, and the TPU film are laminated together; the wear-resistant layer is woven from wear-resistant yarns; the tear-resistant layer is a three-dimensional fabric woven from high-strength fiber yarns; the high-strength fiber yarns are divided into three groups, and the three groups of high-strength fiber yarns are at 60° to each other.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant yarn is polypropylene basalt filament wrapped yarn.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the high-strength fiber yarn is high-strength nylon 6 filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant layer is a double-structured layer.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant layer is coated with a highly wear-resistant water-based polyurethane imitation leather coating on the side away from the tear-resistant layer.

[0010] The beneficial effects of this utility model are as follows: Based on the tear-resistant and wear-resistant sofa fabric of this utility model, the tear-resistant layer is a three-dimensional fabric with relatively uniform load-bearing capacity in all directions. Regardless of whether the force direction is along the yarn direction, there is no obvious weak direction that resists shear deformation and shear damage. Even for thinner fabrics, the dimensional stability is very good. When subjected to normal external force impact, the fabric is relatively uniformly deformed in the circumferential direction, and it is not easy for local stress concentration in two-dimensional fabrics to cause yarn breakage. It has excellent tear resistance. The wear-resistant layer is made of wear-resistant yarns interwoven together and combined with double weave, which helps to reduce pilling and wear caused by long-term sitting pressure.

[0012] In the diagram: 1-Tear-resistant layer, 2-Abrasion-resistant layer, 3-TPU film. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combination Figure 1 This embodiment provides a detailed description of a tear-resistant and abrasion-resistant sofa fabric, comprising: a tear-resistant layer 1, with abrasion-resistant layers 2 laminated on both sides of the tear-resistant layer 1, and a TPU film 3 laminated between the tear-resistant layer 1 and the abrasion-resistant layer 2; the abrasion-resistant layer 2, the tear-resistant layer 1, and the TPU film 3 are laminated together; the abrasion-resistant layer 2 is woven from abrasion-resistant yarns; the tear-resistant layer 1 is a three-dimensional fabric woven from high-strength fiber yarns; the high-strength fiber yarns are divided into three groups, with the three groups of high-strength fiber yarns at 60° to each other.

[0016] Specifically, a lamination method is used to laminate the wear-resistant layer 2 and the tear-resistant layer 1 with the TPU film 3. The lamination speed is 0.1 m / s, the TPU hot melt adhesive powder application rate is 15 g / m², the lamination temperature is 130℃, the lamination pressure is 15 MPa, and the thickness of the TPU film 3 after lamination is 0.5 mm. Due to the inherent waterproof and breathable properties of the TPU film 3, the waterproof performance of the tear-resistant and wear-resistant sofa fabric obtained through lamination is significantly improved.

[0017] In triaxial fabrics, multiple triangular structures exist. Since triangles are more stable than rectangles, the self-locking function of triaxial fabrics is more stable, ensuring tight contact between yarns and reducing slippage of interlaced yarns, resulting in good mechanical stability. The load-bearing capacity of triaxial fabrics is relatively uniform in all directions. Regardless of whether the force is along the yarn direction, there are no obvious weak directions that resist shear deformation and shear failure. Even thinner fabrics exhibit good dimensional stability. When subjected to normal external force impact, the fabric deforms relatively uniformly in the circumferential direction, reducing the likelihood of localized stress concentration in two-dimensional planar fabrics that could lead to yarn breakage, thus exhibiting excellent tear resistance.

[0018] Furthermore, the wear-resistant yarn is a polypropylene basalt filament wrapped yarn. The spinning of polypropylene basalt filament wrapped yarn adopts a parallel spinning method. Specifically, the basalt filament is unwound from the bobbin, first passing through a tensioner to apply a certain tension, then passing through a guide rod and the front roller, and entering a high-speed rotating hollow spindle. A bobbin is inserted into the spindle, rotating with the spindle and winding the polypropylene filament. When the spindle rotates, the polypropylene filament unwound from the bobbin merges with the basalt filament and enters the hollow spindle. Under the action of winding tension, both the polypropylene filament and the basalt filament move downward. Since the spindle and the filament bobbin rotate together, the polypropylene filament wraps around the surface of the basalt filament once with each rotation. In this way, the polypropylene filament is wrapped around the basalt filament, forming polypropylene basalt filament wrapped yarn. Then it is output through the output roller, and enters the winding device through the yarn guide hook and the yarn guide nozzle to obtain polypropylene basalt filament wrapped yarn.

[0019] Furthermore, the high-strength fiber yarn is high-strength nylon 6 filament. The high-strength nylon 6 filament is prepared from semi-dull polyamide 6 chips with a relative viscosity of 2.485 through a melt spinning-multi-stage stretching process. Specifically, the fiber exhibits its maximum breaking strength of 7.23 cN / dtex when the stretch ratio is 1.145, the secondary stretch ratio is 3.12, the primary stretching temperature is 55°C, and the secondary stretching temperature is 178°C.

[0020] Furthermore, the abrasion-resistant layer 2 is a double-weave fabric. Specifically, the warp density of the abrasion-resistant layer 2 is 200 threads / 10cm, and the weft density is 60 threads / 10cm. The higher warp density of the double-weave fabric, combined with the abrasion-resistant yarns, helps reduce pilling and wear caused by long-term sitting pressure in the abrasion-resistant layer 2.

[0021] Example 2

[0022] Based on Example 1, a highly abrasion-resistant waterborne polyurethane faux leather coating is attached to the side of the abrasion-resistant layer 2 away from the tear-resistant layer 1. Specifically, the process for the highly abrasion-resistant waterborne polyurethane faux leather coating is as follows: the mass fractions of thickener, leveling agent, crosslinking agent, and pigment relative to polyurethane are 1.0%, 0.2%, 3%, and 4%, respectively; the mass fractions of wetting agent and defoamer are fixed at 2% and 0.2%, respectively; the transfer temperature is 120℃; the transfer time is 20s; the resulting coating has a 10% modulus of 0.26MPa, a tensile strength of 6.58MPa, and an elongation at break of 842.52%; the faux leather coated fabric has a dry abrasion resistance rating of 3-4, a wet abrasion resistance rating of 3, and a dry / wet rubbing color fastness rating of 4-5.
