Description

Technical Field

[0001] This utility model relates to a weft-twisted imitation memory fabric, belonging to the field of textile fabric technology. Background Technology

[0002] The concept of shape memory fabric originated from the shape memory function of some alloy products. This means that a product with a certain original shape, after being deformed and fixed, can return to its initial shape and properties under specific external conditions, such as heat, mechanical, light, magnetic, or electrical stimuli. Later, this concept was introduced into the textile industry, leading to the development of shape memory fibers. Fabrics woven from these fibers are called shape memory fabrics.

[0003] While memory fabrics offer superior performance—clothes made from them can maintain any shape and exhibit any wrinkles independently without external support, and can completely return to a smooth state without leaving any creases after being gently brushed by hand, exhibiting permanent shape retention—the high cost of raw materials limits their application. To reduce costs while meeting market demands for similar wrinkle-resistant properties to memory fabrics, this application provides a weft-twisted imitation memory fabric. Utility Model Content

[0004] The purpose of this invention is to provide a weft-twisted imitation memory fabric, which aims to have better elasticity and wrinkle resistance, achieving similar performance requirements to memory fabrics in terms of wrinkle resistance.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a weft-twisted imitation memory fabric, comprising: a fabric body, wherein the fabric body is a double-layered fabric with plain weave on both sides, formed by interlacing warp and weft yarns; the warp yarns include an outer warp and an inner warp; the outer warp is an elastic anti-pilling yarn; the inner warp is an elastic antibacterial yarn; the weft yarns include an outer weft and an inner weft; the outer weft is a high-twist anti-pilling yarn; the inner weft is a high-twist moisture-wicking yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic anti-pilling yarn has spandex filament as the core and is wrapped with double anti-pilling polyester fiber on the outside.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic antibacterial yarn is an antibacterial PTT fiber filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the high-twist anti-pilling yarn is a soft spun viscose high-twist yarn.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the high-twist moisture-absorbing yarn is Lyocell linen high-twist yarn.

[0010] The beneficial effects of this utility model are as follows: Based on the weft-twisted imitation memory fabric of this utility model, the main warp yarns of the fabric are all elastic yarns, which gives the fabric good elastic recovery ability in the warp direction. The weft yarns are all high-twist yarns. High-twist yarns can achieve elastic recovery by relying on the internal stress stored by twisting, so that the fabric has wrinkle-resistant properties similar to memory fabrics, which meets the market demand for wrinkle-resistant properties of memory fabrics, and at the same time can also enhance the anti-pilling effect of the main body of the fabric. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of the weft-twisted imitation memory fabric involved in this utility model; In the diagram: 1-outer longitude, 2-inner longitude, 3-outer latitude, 4-inner latitude. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Combination Figure 1 This embodiment provides a detailed description of a weft-twisted imitation memory fabric, comprising: a fabric body, wherein the fabric body is a double-layered fabric with plain weave on both sides, formed by interlacing warp and weft yarns; the warp yarns include an outer warp 1 and an inner warp 2; the outer warp 1 is elastic; the inner warp 2 is elastic antibacterial yarn; the weft yarns include an outer weft 3 and an inner weft 4; the outer weft 3 is a high-twist anti-pilling yarn; and the inner weft 4 is a high-twist moisture-wicking yarn.

[0014] During the weaving process, the ratio of the outer warp 1 and inner warp 2, and the outer weft 3 and inner weft 4 to the main body of the fabric is 1:1. The upper and lower layers of the fabric are woven sequentially according to the weft ratio. When weaving the upper layer, the outer warp 1 is divided into upper and lower layers according to the weave requirements and interweaves with the outer weft 3, while the inner warp 2 is completely submerged in the lower layer of the fabric and does not interweave with the outer weft 3. When weaving the lower layer, that is, when the inner weft 4 is introduced, the outer warp 1 yarn must be fully lifted, and the inner warp 2 is divided into upper and lower layers according to the weave requirements and interweaves with the inner weft 4, while the outer warp 1 and the inner weft 4 do not interweave.

[0015] Furthermore, the elastic anti-pilling yarn uses spandex filament as its core and is wrapped with double-anti-pilling polyester fibers. The molecular chain of spandex consists of soft and hard segments. The soft segments possess good flexibility and a low glass transition temperature, allowing them to bend and stretch freely at room temperature, providing spandex with stretchability. The hard segments have high rigidity and cohesive energy. They are interconnected through intermolecular forces, forming physical cross-linking points. These cross-linking points limit excessive slippage of the molecular chains when spandex is stretched, and when the external force is removed, they promote the molecular chains to return to their original positions, thus giving spandex good elastic recovery properties. Yarn with spandex as its core and non-elastic fibers wrapped around it possesses both elasticity and the characteristics of the outer fiber, imparting elasticity to the fabric. Double-anti-pilling polyester fibers refer to polyester fibers that are anti-pilling, anti-static, and possess anti-fuzzing properties obtained by modifying ordinary polyester fibers through chemical or physical methods. The breaking strength, breaking strength unevenness, and breaking elongation of double-resistant polyester fiber are all lower than those of ordinary polyester fiber and are close to those of viscose fiber. The fuzz on the surface of its fabric is easily abraded and will not form a large number of pills, thus having a good anti-pilling effect. The moisture regain of double-resistant polyester fiber is greater than 0.56%, which is higher than that of ordinary polyester fiber. Moreover, the internal porous structure of double-resistant polyester fiber has good wicking performance, which enhances the conductivity of double-resistant polyester and gives it good antistatic properties.

[0016] Furthermore, the elastic antibacterial yarn is an antibacterial PTT fiber filament. PTT fiber has a smooth and rounded surface and is a semi-crystalline thermoplastic polyester. In the chemical structure of PTT fiber, there is a trans-para-para-trans conformation with the lowest energy, which presents a distinct "Z" shaped conformation. At the same time, there are three methylene units in the molecular chain link, so a strange carbon effect is generated between the molecular chains. This molecular structure makes PTT fiber have the deformation ability of a coil spring and its resilience is better than PET and PBT. Antibacterial PTT fiber filaments are prepared by melt spinning silver-based antibacterial masterbatch and PTT chips using a masterbatch addition method. They possess the excellent resilience of PTT fibers, and the silver-based antibacterial agent has a good antibacterial effect on a broad spectrum of bacteria. When bacteria and viruses come into contact with the fiber surface, the active ingredient silver ions in the antibacterial agent can penetrate the negatively charged bacterial cell wall and quickly bind to sulfhydryl groups, amino groups, etc. on the enzyme proteins in the bacteria, destroying the normal structure of proteins and nucleic acids, causing microorganisms to die or lose their reproductive ability, thereby achieving the effects of antibacterial and bactericidal action. Therefore, antibacterial PTT fiber filaments also have a good antibacterial effect.

[0017] Furthermore, the high-twist anti-pilling yarn is a soft-spun viscose high-twist yarn. Viscose fiber is a regenerated cellulose fiber, and its yarns and fabrics are widely popular due to their low price and good performance. Based on the high moisture absorption and comfort of viscose fiber, the high-twist viscose yarn enhances the potential of the yarn by increasing twist. Specifically, the twist of the soft-spun viscose high-twist yarn is 150 twists / 10cm. The soft-spun processing technology involves installing a smoothing and polishing device at the twisting triangle area of ​​the yarn. The surface of the smoothing and polishing device has a high-temperature ironing zone, which heats and irons the yarn during high-speed transfer. Simultaneously, the smoothing and polishing device also generates a holding force on the yarn. When the viscose fiber comes into contact with the high-temperature ironing surface of the smoothing and polishing device, the viscose fiber reaches its glass transition temperature, significantly reducing fiber rigidity and increasing flexibility. This enhances the controllability of the fiber during twisting, reducing fiber fuzz in uncontrolled areas. At the same time, the increased softness reduces relative slippage between fibers, ensuring cohesion between the viscose fiber yarns. The smoothing and finishing device improves the yarn structure by providing a smooth grip. Fibers that were exposed and failed to be wound into the yarn body are softened by ironing and, under the new gripping point, are re-wound into the yarn body through twisting torque. This allows for full transfer of fibers within the yarn, effectively reducing yarn fuzz. The smoothing and finishing viscose high-twist yarn has advantages such as less fuzz, uniform yarn evenness, high strength, low twist shrinkage, and good anti-pilling properties, which help improve the anti-pilling performance of the fabric.

[0018] Furthermore, the high-twist, moisture-wicking yarn is a lyocell-linen high-twist yarn. Specifically, the lyocell-linen high-twist yarn is a lyocell / linen 65 / 35 high-twist yarn with a twist of 150 twists / 10cm. Lyocell fiber is a man-made cellulose fiber with a circular cross-section and smooth longitudinal morphology. Compared with other natural plant fibers, it has high strength, high wet modulus, and similar dry and wet strength. Linen is one of the earliest natural fibers used by mankind, possessing functions such as temperature regulation, anti-allergy, anti-static, and antibacterial properties. Due to its good moisture absorption, linen can absorb up to 20 times its own weight in water, resulting in fabrics with a dry feel, which is favored by consumers.

[0019] Both the outer weft 3 and inner weft 4 are high-twist yarns. After twisting, the fibers intertwine and interlock, forming a tight fiber bundle structure. This allows for a more even distribution of external forces during stretching and friction, reducing the probability of weft yarn breakage during weaving and extending the lifespan of the finished fabric. Furthermore, twisting can incorporate loose fibers from the yarn surface into the yarn body, reducing exposed fuzz, enhancing fiber cohesion, and minimizing pilling caused by fuzz entanglement during wear.

[0020] High-twist yarns possess "stress memory" within their fibers. When a fabric is wrinkled by external force, the yarn can slowly recover its smoothness through its own elastic recovery force—that is, the internal stress stored during twisting. This is one of the core technological principles of "memory fabrics." Twisting makes the weft yarn structure more compact, reducing the space for "bulging" or "shrinking" of the fibers during washing and drying, thereby reducing the fabric's shrinkage rate and preventing deformation after long-term use, such as clothes losing their shape or bunching after washing.

[0021] 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.
