Description
Technical Field
[0001] The present disclosure relates to the technical field of composite fabrics, and more precisely, to a cashmere nanofiber membrane composite fabric. Background Art
[0002] Cashmere is a precious textile raw material with excellent softness and warmth retention. Fabrics woven from it are light, soft, smooth, and comfortable to wear, and are known as "soft gold". Among them, worsted cashmere can achieve a thin and dense fabric, but a single pure cashmere fabric lacks a sense of structure and has poor windproof effect, making it difficult to be used in outdoor or light outdoor textile products. This greatly limits the product categories of cashmere and is not conducive to the development of cashmere. Therefore, it is necessary to composite cashmere with other materials to broaden the product categories of cashmere fabrics.
[0003] In cashmere composite fabrics, due to the presence of scale layers in cashmere, felting is likely to occur during the weaving process, resulting in severe changes in width and gram weight. Therefore, when cashmere is composite with traditional PTFE membranes and TPU membranes, large-scale wrinkling is likely to occur, the washing size stability is poor, and the breathability and elasticity are insufficient. Wearing it feels stuffy and restrictive, and it cannot maintain the excellent hand feeling of cashmere fabrics, which will seriously damage the style of cashmere fabrics. Therefore, developing a cashmere composite fabric with breathability, waterproofness, and the ability to maintain the excellent hand feeling of cashmere has become an urgent problem to be solved. Summary of the Utility Model
[0004] In view of this, the embodiments of the present disclosure provide a cashmere nanofiber membrane composite fabric to solve the technical defects existing in the prior art.
[0005] To achieve the above object, the present disclosure adopts the following technical solutions:
[0006] The present disclosure provides a cashmere nanofiber membrane composite fabric, including:
[0007] A base layer, which is configured to be woven from pure cashmere yarns;
[0008] A nanofiber membrane, which is configured to be covered on the base layer by adhesive bonding;
[0009] A lining layer, which is arranged on the nanofiber membrane and is configured to be fixed to the nanofiber membrane by sewing or hot stamping.
[0010] In an embodiment of the present disclosure, the tissue structure of the base layer is one of plain weave, twill weave, and satin weave.
[0011] In an embodiment of the present disclosure, the base layer is woven by the cross of warp yarns and weft yarns, and the side of the base layer away from the nanofiber membrane has short and smooth hairs.
[0012] In one embodiment of the present disclosure, the warp and weft yarns of the base layer are single - strand or double - strand pure cashmere yarns.
[0013] In one embodiment of the present disclosure, the thickness of the nanofiber membrane is 10 - 15 μm; the thickness of the nanofiber membrane is less than that of the base layer and the lining layer.
[0014] In one embodiment of the present disclosure, the lining layer is woven from silk, polyester fiber and nylon.
[0015] In one embodiment of the present disclosure, the polymer used in the nanofiber membrane is polyurethane (PU).
[0016] In one embodiment of the present disclosure, the grammage of the nanofiber membrane is 5 - 7 gsm.
[0017] In one embodiment of the present disclosure, the base layer is woven from double - strand 80 - count warp yarns and double - strand 80 - count weft yarns, with a width of 150 mm.
[0018] In one embodiment of the present disclosure, the base layer is woven from single - strand 50 - count warp yarns and single - strand 70 - count weft yarns, with a width of 150 mm.
[0019] For the cashmere nanofiber membrane composite fabric provided by the present disclosure, since the nanofiber membrane has good waterproof and breathable properties, strong elasticity and light weight, while retaining the elasticity and feel of the cashmere itself, it can effectively improve the toughness of the composite fabric. And to avoid direct contact between the nanofiber membrane and the human body surface, a lining layer is added to the nanofiber membrane to prevent the sticky feeling caused by the user's contact with the nanofiber membrane after sweating during exercise. Moreover, the lining layer has good friction and strength, which can make the composite fabric stronger and more durable. At the same time, since the lining layer is made of silk, polyester fiber and nylon, the formed lining is thin and does not affect the softness of the fabric. Thus, the formed cashmere nanofiber membrane composite fabric has the advantages of good elasticity, breathable and waterproof, windproof and warm - keeping.

[0032] The present disclosure relates to a cashmere nanofiber membrane composite fabric, which includes a base layer, a nanofiber membrane, and a lining layer. The base layer is woven from pure cashmere yarns. The nanofiber membrane is adhesively covered on the base layer. The lining layer is disposed on the nanofiber membrane and fixed to the nanofiber membrane by sewing or hot pressing.
[0033] For the cashmere nanofiber membrane composite fabric provided by the present disclosure, since the nanofiber membrane has good waterproof and breathable properties, strong elasticity, and light weight, while retaining the elasticity and feel of the cashmere itself, it can effectively improve the toughness of the composite fabric. Moreover, a lining layer is added on the nanofiber membrane to prevent the sticky feeling caused by the user's contact with the nanofiber membrane after sweating during exercise. And the lining layer has good friction and strength, which can make the composite fabric more firm and durable. Thus, the formed cashmere nanofiber membrane composite fabric has the advantages of good elasticity, breathable waterproof, windproof and warm.
[0034] For the sake of easy understanding, hereinafter, with reference to Figure 1 , the specific structure and working principle of the cashmere nanofiber membrane composite fabric of the present disclosure will be described in detail in combination with an embodiment.
[0035] As Figure 1 shown, the present disclosure provides a cashmere nanofiber membrane composite fabric, including: a base layer 1, a nanofiber membrane 2, and a lining layer 3. The base layer 1 is configured to be woven from pure cashmere yarns; the nanofiber membrane 2 is configured to be covered on the base layer 1 by adhesive bonding; the lining layer 3 is disposed on the nanofiber membrane 2 and is configured to be fixed to the nanofiber membrane 2 by sewing or hot stamping.
[0036] Specifically, the cashmere nanofiber membrane composite fabric provided in the present application is generally used for outdoor clothing fabrics that require waterproof and windproof properties. The composite fabric provided in the present application is composed of the pure cashmere fabric of the base layer 1 and the nanofiber membrane 2, and then the lining layer 3 is added according to actual needs. Among them, the nanofiber membrane 2 is covered on the base layer 1 by adhesive bonding. The lining layer 3 can be fixed in two ways. In one embodiment of the present disclosure, the lining layer 3 can be fixed to the nanofiber membrane 2 by sewing. In this way, the above-mentioned lining layer 3 can be disassembled, so the flexibility is better, and it is convenient to disassemble the lining layer 3 for cleaning; in another embodiment of the present disclosure, the lining can be fixed to the nanofiber membrane 2 by hot stamping. In this case, the above-mentioned lining layer 3 cannot be disassembled, so the connection between the lining layer 3 and the nanofiber membrane 2 is more stable and not easily deformed.
[0037] As Figure 1 shown, in one embodiment of the present disclosure, the tissue structure of the base layer 1 is one of plain weave, twill weave, and satin weave.
[0038] Specifically, the organizational structure of the base layer 1 can be one of plain weave, twill weave, and satin weave. Among them, plain weave is an organizational structure in which each warp yarn and weft yarn are alternately interwoven, that is, a structure formed by an "over-one-under-one" interweaving method. Each warp yarn and weft yarn only passes through one adjacent yarn. Since the organizational structure of the base layer 1 is set as plain weave, the base layer 1 can have good strength and durability, can withstand a certain amount of mechanical stress without being easily damaged, and thus improve the strength and durability of the composite fabric. In twill weave, the warp yarn or weft yarn skips two or more yarns on adjacent weft yarns or warp yarns, forming an inclined texture, usually showing an interweaving method of "two-over-two" or "three-over-three", and the surface presents an obvious diagonal texture. Twill weave can make the base layer 1 more beautiful, enhance the softness and elasticity of the fabric, and the resulting composite fabric has a more comfortable hand feeling. In satin weave, the warp yarn or weft yarn forms a longer floating line due to skipping more yarns. However, the more floating lines, the smoother the fabric surface and the higher the gloss. Therefore, the base layer 1 woven with satin weave has high aesthetics, very good softness and drapability. Based on this, the fabric formed by laminating the base layer 1 with satin weave and the nanofiber membrane 2 is more suitable for making high-end clothing and decorative items. The choice of which organizational structure depends on the use of the final product and the required characteristics. Plain weave is suitable for occasions that require strength and durability; twill weave has both good appearance and certain durability; while satin weave is suitable for products that pursue aesthetics and softness. In practical applications, the most suitable organizational structure can be selected according to specific requirements.
[0039] As Figure 1 shown, in an embodiment of the present disclosure, the base layer 1 is woven by cross-weaving warp yarns and weft yarns, and the side of the base layer 1 away from the nanofiber membrane 2 has short plush.
[0040] Specifically, the base layer 1 is woven by crossing warp and weft yarns made of pure cashmere. Among them, the warp yarns are longitudinally arranged yarns, usually thinner and with high strength to withstand the tension during the weaving process. The weft yarns are the yarns that are horizontally interspersed between the warp yarns and are used to interweave with the warp yarns to form a fabric. In an embodiment of the present disclosure, the warp yarns and the weft yarns are perpendicularly interwoven. After each warp yarn continuously passes above three weft yarns, it passes under the fourth weft yarn adjacent to the third weft yarn from above the third weft yarn, and then passes above the other three weft yarns adjacent to the other side of the fourth weft yarn from under the fourth weft yarn, and based on this, cyclic interweaving is carried out to form the base layer 1. Since the base layer 1 is woven from cashmere yarns, there will be exposed short cashmere on the side not covered by the nanofiber membrane 2. By performing a raising operation on the above-mentioned short cashmere, short smooth hairs can be formed on the side of the base layer 1 away from the nanofiber membrane 2. The short smooth hairs can increase the warmth retention and comfort of the fabric. At the same time, the short smooth hairs can also improve the hand feeling of the fabric, making the composite fabric softer. Combining the base layer 1 with short smooth hairs and the nanofiber membrane 2 can enhance its breathability and waterproof performance while maintaining the comfort of the fabric.
[0041] In an embodiment of the present disclosure, the warp and weft yarns of the base layer 1 are single-strand or double-strand pure cashmere yarns.
[0042] Specifically, as Figure 1 shown, the warp and weft yarns of the base layer 1 are single-strand or double-strand pure cashmere yarns. Among them, the single-strand yarn refers to an un-twisted single yarn, usually softer but with lower strength. Therefore, the single-strand yarn is more suitable for fabrics that require extremely soft and delicate hand feeling. The double-strand yarn refers to twisting two single-strand yarns into one yarn. The double-strand yarn is stronger and tougher than the single-strand yarn and is more suitable for use under conditions that require higher strength and wear resistance. In practical applications, the most suitable yarn can be selected for weaving according to specific requirements.
[0043] In an embodiment of the present disclosure, the thickness of the nanofiber membrane 2 is 10 - 15 μm; the thickness of the nanofiber membrane 2 is less than that of the base layer 1 and the lining layer 3.
[0044] Specifically, as Figure 1As shown, the thickness of the nanofiber membrane 2 is 10 - 15 μm, and the thickness of the nanofiber membrane 2 is much smaller than that of the base layer 1 and the lining layer 3. Such a thickness makes the nanofiber membrane 2 very thin and light, but still has excellent waterproof and breathable properties. This is because the nanofiber membrane 2 is usually composed of nanofibers, and the diameters of these fibers are generally between a few nanometers and a few hundred nanometers. These nanofibers can form a high-density network structure, providing excellent breathable and waterproof properties. The thinner nanofiber membrane 2 can save materials, reduce production costs, and at the same time reduce the overall weight of the composite material. The thickness of 10 - 15 μm ensures that the nanofiber membrane 2 can be well combined with the base layer 1 and the lining layer 3 without affecting the performance of the overall composite fabric. Among them, the thinner nanofiber membrane 2 can be used as the functional layer in the composite fabric, while the thicker base layer 1 and the lining layer 3 provide structural support, so as to achieve the best combination of structure and function.
[0045] In one embodiment of the present disclosure, the polymer used for the nanofiber membrane 2 is polyurethane (PU).
[0046] Specifically, as Figure 1 shown, the polymer used for the nanofiber membrane 2 is polyurethane (PU). This is because polyurethane (PU) has excellent flexibility, which makes the nanofiber membrane 2 made of it not easily break when bent or stretched. Polyurethane (PU) also has good abrasion resistance and can withstand repeated friction without being easily damaged. Moreover, the polyurethane (PU) nanofiber membrane 2 has good waterproof and breathable properties, which can block liquid water and allow water vapor to pass through. Among them, the nanofiber membrane 2 can be prepared by the electrospinning method, that is, using a high-voltage electrostatic field to form extremely fine fibers from a polymer liquid through the action of charges, and then stretching and orienting the fibers on the substrate by the electric field force. During this process, the jet is stretched and thinned under the traction of the electric field force and randomly deposited on the receiver to form the nanofiber membrane 2. In addition, the solution blowing method can also be used to prepare the nanofiber membrane 2. This method is similar to the electrospinning method, but does not rely on the electric field force, but disperses the solution into fibers through a high-speed air flow. In practical applications, the most suitable method can be selected according to the actual situation for spinning.
[0047] In one embodiment of the present disclosure, the grammage of the nanofiber membrane 2 is 5 - 7 gsm.
[0048] Specifically, as Figure 1As shown, the grammage of the nanofiber membrane 2 is 5-7 gsm, that is, the nanofiber membrane 2 is 5-7 grams per square meter. This indicates that the nanofiber membrane 2 used in this application is very light and thin. A light and thin nanofiber membrane 2 usually has better air permeability, which is very important in clothing that needs to maintain air permeability. A light and thin nanofiber membrane 2 is usually softer and more flexible, and is thus more suitable for being compounded with a soft cashmere fabric. Moreover, using a nanofiber membrane 2 with a lower grammage can save materials, thereby reducing production costs.
[0049] In an embodiment of the present disclosure, the lining layer 3 is woven from silk, polyester fiber, and nylon.
[0050] Specifically, as Figure 1 shown, the lining layer 3 is woven from silk, polyester fiber, and nylon. This combination can provide good comprehensive performance, maintaining both the softness and comfort of the fabric made of silk and taking advantage of the durability and easy care characteristics of polyester fiber and nylon materials. Among them, the fabric made of silk has good air permeability and water absorption, is suitable for making clothing close to the skin, and can absorb a certain amount of moisture without feeling damp, helping to keep the skin dry. In the actual application process, the lining layer 3 will be added on the basis of the composite nanofiber membrane 2 on the base layer 1 according to actual needs. There are two specific fixing methods. The first can be to fix the lining layer 3 on the nanofiber membrane 2 by sewing. In this case, the above-mentioned lining layer 3 can be disassembled, so it has better flexibility and is convenient for disassembling the lining layer 3 for cleaning; the second can be to fix the lining on the nanofiber membrane 2 by hot stamping. In this case, the above-mentioned lining layer 3 cannot be disassembled, so the connection between the lining layer 3 and the nanofiber membrane 2 is more stable and not easily deformed.
[0051] In an embodiment of the present disclosure, the base layer 1 is woven from double-strand 80 / 2 warp yarns and double-strand 80 / 2 weft yarns, with a width of 150 mm.
[0052] Specifically, as Figure 1 shown, the base layer 1 can preferably be woven from double-strand 80 / 2 warp yarns and double-strand 80 / 2 weft yarns. Among them, 80 / 2 indicates that the length of 1 gram of yarn is 80 meters. Therefore, the larger the count, the finer the yarn. The width indicates the width of the fabric. 80 / 2 indicates that this is a yarn with a relatively high fineness. Double-strand means that two yarns are twisted together, improving the strength and stability of the yarn. Yarns with a high count make the fabric surface smoother and more uniform, looking more beautiful. Fabrics made of fine yarns usually have good air permeability, which is beneficial to improving the air permeability of the composite fabric and avoiding the lack of air permeability of the composite fabric from bringing a stuffy feeling to users. The relatively small width (150 mm) makes the base layer 1 more flexible during processing and can be cut into different sizes according to needs, suitable for different application scenarios.
[0053] In one embodiment of the present disclosure, the base layer 1 is woven from a single strand of 50 - count warp yarn and a single strand of 70 - count weft yarn, with a width of 150 mm.
[0054] Specifically, as Figure 1 shown, the base layer 1 may also preferably be woven from a single strand of 50 - count warp yarn and a single strand of 70 - count weft yarn. Here, 50 - count means that the length of a 1 - gram yarn is 50 meters, and 70 - count means that the length of a 1 - gram yarn is 70 meters. The width refers to the width of the fabric. Compared with 80 - count yarn, the 50 - count and 70 - count yarns are thicker than the 80 - count yarn, so single - strand yarns can be used for weaving. Using 50 - count warp yarn can provide sufficient strength for the base layer 1, while 70 - count weft yarn can increase the fineness and softness of the base layer 1. This combination can balance the strength and comfort of the fabric. The smaller width (150 mm) makes the base layer 1 more flexible during processing and can be cut into different sizes according to needs, suitable for different application scenarios.
[0055] For the cashmere nano - fiber membrane composite fabric provided by the present disclosure, since the nano - fiber membrane has good waterproof and breathable properties, strong elasticity, and light weight, while retaining the elasticity and feel of the cashmere itself, it can effectively improve the toughness of the composite fabric. And to avoid direct contact between the nano - fiber membrane and the human body surface, a lining layer is added to the nano - fiber membrane to prevent the sticky feeling when the user sweats during exercise and touches the nano - fiber membrane. Moreover, the lining layer has good friction and strength, which can make the composite fabric stronger and more durable. At the same time, the lining layer is made of silk, polyester fiber, and nylon, so the formed lining is thin and does not affect the softness of the fabric. Thus, the formed cashmere nano - fiber membrane composite fabric has the advantages of good elasticity, breathable and waterproof, wind - proof and warm - keeping.
