Description

Technical Field

[0001] This utility model relates to a sofa fabric, specifically an anti-pilling composite sofa fabric. Background Technology

[0002] As people's living standards improve, the requirements for sofa fabrics are no longer limited to aesthetics and comfort, but also include durability and functionality. Traditional sofa fabrics, such as cotton and linen, while excellent in terms of skin-friendliness, may be insufficient in terms of abrasion resistance and pilling resistance.

[0003] Some common sofa fabrics, especially synthetic fibers and their blends, are prone to pilling and tangling due to frequent contact and friction between the user and the sofa, as well as the sofa's folding and stretching. This not only affects the sofa's appearance but also reduces user comfort. Traditional sofa fabrics often have limited functionality and cannot meet multiple needs simultaneously. For example, some fabrics may only focus on softness while neglecting stain resistance and antibacterial properties, failing to meet the diverse functional requirements of modern home living. Therefore, this application provides an anti-pilling composite sofa fabric. Utility Model Content

[0012] In the diagram: 1-Anti-pilling layer, 2-Antibacterial base fabric layer, 3-Dotted hot melt adhesive. 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 an anti-pilling composite sofa fabric, comprising: a fabric body, the fabric body including an anti-pilling layer 1 and an antibacterial base fabric layer 2, the anti-pilling layer 1 and the antibacterial base fabric layer 2 being bonded together by an array of dot-shaped hot melt adhesive 3; the anti-pilling layer 1 being woven from warp and weft yarns; the weft yarns including a first weft yarn and a second weft yarn, the first weft yarn and the second weft yarn being arranged alternately in a 4:1 ratio; the warp yarns and the first weft yarn are anti-pilling yarns; the second weft yarn is a conductive composite yarn; the antibacterial base fabric layer 2 being woven from antibacterial yarns and polyester filaments.

[0016] Specifically, the conductive composite yarn is made of 68.4 tex polyester-viscose colored spun yarn and 22.2 dtex carbon black conductive fiber, processed simultaneously on a doubling machine and a twisting machine. A coarse-fine yarn composite covering method is used to cover the conductive yarn, making it hidden within the coarser colored yarn. Polyester's abrasion resistance is second only to nylon, ranking second among synthetic fibers; therefore, polyester fabrics are strong and durable, achieving a wrinkle-free and iron-free effect after washing. The nylon-based carbon black conductive fiber has a single fiber fineness of 7.7-11.1 dtex and a surface resistivity of 10. 6 -10 7Ω. Viscose fiber is characterized by easy dyeing, good color fastness, and softness and smoothness. The conductive composite yarn is woven with one yarn every four first weft yarns in the weft direction. The anti-pilling layer 1 formed by the embedded conductive composite yarn utilizes the corona discharge of conductive fibers. That is, the conductive fibers in the fabric can distort the electric field around the charged body, forming a non-uniform electric field. When the electric field strength at a certain point reaches a certain value, it increases the speed of charge dissipation, which leads to the corona discharge phenomenon. In this way, the charge generated by friction of the fabric body will dissipate quickly, thus improving the antistatic performance of the fabric body to a certain extent.

[0017] Specifically, the hot melt adhesive used when laminating the anti-pilling layer 1 and the antibacterial base fabric layer 2 is polyurethane hot melt adhesive, with a melt temperature of 100-120℃. The core components of the laminating equipment used during the lamination process are the gluing device and the laminating device. The surface of the engraving roller of the gluing device is distributed with concave dot-shaped glue holes for storing and supplying glue. The dots are arranged regularly, and the spacing between the dots is consistent. The gluing pressure is 19N, the bonding pressure is 29N, and the rolling tension is 20N. The anti-pilling layer 1 and the antibacterial base fabric layer 2 are firmly bonded together by heating and pressing in the laminating device.

[0018] Furthermore, the anti-pilling yarn is 7.78tex / 48f nylon 6 yarn. Nylon 6 yarn with a specification of 7.78tex / 48f has a single filament linear density close to 1.61dtex, a comfortable feel, and achieves a grade 4 rating in both pilling and snagging resistance, meeting daily usage needs.

[0019] Furthermore, the antibacterial yarn is an antibacterial and deodorizing viscose fiber yarn. The antibacterial and deodorizing viscose fiber is prepared by adding Isatis indigotica root extract and diatomaceous earth extract to a viscose spinning solution using a blending spinning method, followed by wet spinning. The antibacterial and deodorizing viscose fiber exhibits antibacterial rates of 92.00%, 86.00%, 83.00%, and 86.00% against Staphylococcus aureus, Escherichia coli, Candida albicans, and Klebsiella pneumoniae, respectively, all demonstrating good antibacterial activity. This is because compounds such as indigo, indirubin, and tryptamine in the Isatis indigotica root extract have significant inhibitory effects on both bacteria and fungi. The antibacterial and deodorizing viscose fiber reduced the concentrations of isovaleric acid, ammonia, and acetic acid by 92.40%, 98.00%, and 88.00%, respectively. This is because diatomaceous earth has many micropores, a large specific surface area, and strong adsorption capacity, which gives it a strong adsorption effect on odorous gases. In the spinning process, diatomaceous earth is added to the fiber, giving it excellent deodorizing function.

[0020] Furthermore, the polyester filament is coconut charcoal modified polyester fiber filament. Coconut charcoal modified polyester fiber is produced by heating the fibrous material of coconut shells to about 1600℃ to generate activated carbon, which is then mixed with polyester and other chemical substances to form coconut charcoal masterbatch. This masterbatch is then diluted with polyester as a carrier and drawn into filaments, possessing functions such as odor adsorption, stain prevention, and moisture prevention.

[0021] Example 2

[0022] The difference from Example 1 is that the anti-pilling yarn is an anti-pilling polyester-bamboo fiber blended yarn. Specifically, the specifications of the anti-pilling polyester-bamboo fiber blended yarn are T65 / B35 18.5tex blended yarn. The anti-pilling polyester fiber is produced using a modification method, which reduces the crystallinity of the fiber, resulting in relatively lower strength and more brittleness. The fuzz formed by the fibers in the fabric is easily shed, reducing the probability of entanglement into pills, thus improving the anti-pilling performance of the fabric. Compared with ordinary polyester of the same specifications, anti-pilling polyester fiber has lower strength, better anti-pilling performance, a soft and elastic hand feel, fast moisture absorption and release, good breathability, and good dyeability. Bamboo fiber is a natural fiber produced using a combination of physical and chemical methods. It is obtained by removing impurities such as lignin, pentosans, bamboo powder, and pectin from natural bamboo through mechanical, physical, and biotechnological methods, resulting in fiber directly separated from the bamboo. It possesses excellent antibacterial properties, and its cross-section is filled with pores of varying sizes, allowing it to absorb and evaporate moisture instantly. The anti-pilling polyester bamboo fiber T65 / B35 18.5tex blended yarn has a single yarn breaking strength of 14.6 cN / tex, a soft and full hand feel, and good anti-pilling properties.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
