Abstract
Description
Technical Field
[0001] The utility model relates to the field of thermal insulation fabrics, in particular to a stretch thermal insulation fabric. Background Art
[0002] Traditional thermal fabrics have poor breathability when used. Long-term use will cause the human body to feel hot and damp, and even cause acne. Fabrics with good breathability have poor windproof and thermal insulation properties, which affects their use effect. When using the product, the side away from the human body will be subjected to greater tensile force during exercise, and its stretching length will also be longer. Long-term use will cause the outer fabric to be damaged, pilling, or even tearing.
[0003] Therefore, it is necessary to propose a stretch thermal insulation fabric to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a stretch thermal insulation fabric to solve the problem that the above outer layer fabric has poor tensile strength and cannot provide both thermal insulation and breathability.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stretch thermal fabric, comprising a fabric main body, the fabric main body being formed by stacking an external diffusion layer, an elastic protective layer, an elastic support layer, and an internal capture layer, the external diffusion layer being bonded to the upper surface of the elastic protective layer by spraying glue, the elastic protective layer being first bonded to the upper surface of the elastic support layer by spraying glue, and then the elastic protective layer being sewn to the elastic support layer by a second elastic thread, the lower surface of the elastic support layer being connected to the upper surface of the internal capture layer by hot pressing bonding, the elastic support layer comprising a thermal elastic fabric and a conductive fabric, the thermal elastic fabric and the conductive fabric being alternately placed, and the thermal elastic fabric and the conductive fabric being connected by sewing.
[0006] Preferably, the external diffusion layer comprises an outer flannel base surface, a surface of the outer flannel base surface away from the elastic protective layer comprises long flat velvet, and the outer flannel base surface is in close contact with the elastic protective layer.
[0007] Preferably, the outer diffusion layer, the elastic protection layer, the elastic support layer and the inner capture layer are sutured and fixed by means of a first elastic thread.
[0008] Preferably, the inner capture layer comprises an inner flannel base surface and short velvet, the inner flannel base surface is tightly bonded to the lower surface of the elastic support layer by heat pressing, and the side of the inner flannel base surface away from the elastic support layer has short velvet.
[0009] Preferably, the elastic protective layer is interfered with by the second elastic thread to be wavy, the second elastic thread is perpendicular to the wave direction, and the first elastic thread and the second elastic thread are perpendicular to each other.
[0010] Technical effects and advantages of this utility model:
[0011] 1. By setting up an elastic support layer, locally interspersed with warm elastic fabric and conductive fabric, and increasing or decreasing the conductive fabric according to the usage scenario, the fabric has a good warming effect and provides good breathability. Because the area of the conductive fabric is much smaller than the area of the warm elastic fabric, the internal temperature will not change significantly when the air circulates, making it suitable for long-term use;
[0012] 2. When there is moisture inside, the short velvet can quickly capture moisture and conduct it to the inner velvet base, which then conducts it to the elastic protective layer through the conductive fabric. The elastic protective layer can quickly conduct the moisture to the outer velvet base, and finally the long velvet is released into the air, making the fabric have very good moisture-wicking ability. The short velvet can quickly capture moisture, and the long velvet can quickly release moisture, so that the user can always stay dry and can be used for a long time.
[0013] 3. Because the elastic protective layer is wavy, it has many peaks. The peaks are bonded to the surface of the outer flannel base and the elastic support layer. When the main body of the fabric undergoes elastic deformation, the elastic protective layer will unfold, so that the fabric can still maintain a good warmth effect when stretched, and will not cause the fabric to be too thin in some areas due to stretching.
[0014] 4. By setting up an elastic protective layer, the side of the fabric away from the human body can have a higher yield capacity, avoiding damage to the fabric caused by strong stretching, making the fabric more widely used in products such as sleeping bags. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] The utility model provides Figure 1 - Figure 3 The elastic thermal fabric shown includes a fabric body 1, which is formed by stacking an external diffusion layer 2, an elastic protective layer 3, an elastic support layer 4, and an internal capture layer 5. The elastic protective layer 3 is made of nylon fabric, and the external diffusion layer 2 and the internal capture layer 5 are both made of pure cotton elastic flannel. The overall structure of the fabric is relatively thick and is suitable for manufacturing mountaineering clothes, cotton-padded sleeping bags and other scenarios.
[0021] 100% cotton stretch velveteen boasts excellent elasticity, which is its most prominent advantage. It is soft and comfortable. The velveteen's pile is plump and smooth, creating a pleasant sensation when touched. Wearing this fabric is particularly comfortable in cool weather, as it provides excellent warmth. It has a soft sheen and a striking appearance. Fabrics made with this fabric can achieve a striking appearance, making them more appealing to consumers. The fabric also offers exceptional abrasion resistance. Compared to standard fabrics, products made with 100% cotton stretch velveteen are generally 4-5 times more durable.
[0022] The strength and wear resistance of nylon fabric not only rank first among fibers, but also among all kinds of fabrics. Its wear resistance is many times higher than that of other fiber fabrics of the same type. Therefore, the durability of nylon fabric is particularly good, and this is one of the reasons why nylon is often used as a raw material for mountaineering clothes and winter clothing. Clothes made of nylon are usually durable and not easy to wear. The moisture absorption of nylon fabric is relatively good among synthetic fiber fabrics. Therefore, the clothes we make with nylon fabric are more comfortable to wear than polyester clothes. In addition, nylon fabric has good anti-moth and anti-corrosion properties and is easier to preserve intact.
[0023] The outer diffusion layer 2 is bonded to the upper surface of the elastic protective layer 3 by spraying glue. The outer diffusion layer 2 includes an outer velvet base 21. The outer velvet base 21 has a long velvet 22 on the side away from the elastic protective layer 3. The outer velvet base 21 is tightly fitted with the elastic protective layer 3. The inner capture layer 5 includes an inner velvet base 51 and a short velvet 52. The inner velvet base 51 is tightly bonded to the lower surface of the elastic support layer 4 by hot pressing. The inner velvet base 51 has a short velvet 52 on the side away from the elastic support layer 4. When in use, the short velvet The velvet 52 is located on the side that fits the human body, and the long velvet 22 is located on the side in contact with the air. Due to the characteristics of the short velvet 52, its contact area with the air is large, and the short velvet 52 is made of pure cotton, so it can quickly capture moisture in the air and conduct it to the inner velvet base 51. The structure of the long velvet 22 has a larger contact area with the air than the short velvet 52, so the long velvet 22 can quickly dissipate the moisture of the outer velvet base 21 into the air, so that the outer velvet base 21 remains dry and the evaporation rate is increased.
[0024] The elastic support layer 4 includes a warm elastic fabric 41 and a conductive fabric 42. The warm elastic fabric 41 and the conductive fabric 42 are placed alternately and connected by sewing. The warm elastic fabric 41 is made of acrylic fabric, and the conductive fabric 42 is made of moisture-absorbing and perspiration-wicking fabric.
[0025] Acrylic fabrics are highly elastic. Its elasticity is similar to that of natural wool, maintaining a 65% rebound rate at 20% elongation, making the fabric soft and stretchable. Acrylic also offers excellent thermal insulation. Its density is lower than wool, and its warmth retention is even about 15% higher than comparable wool fabrics. It is also highly light-resistant. Acrylic is highly resistant to sunlight, with its strength decreasing by only 5% after a year of outdoor exposure. Acrylic is also highly resistant to acids and certain alkalines. It also offers excellent heat resistance. Acrylic can be ironed at temperatures of 130-140°C, making it suitable for heat-resistant clothing. However, its low hygroscopicity may make it feel stuffy when worn. Acrylic also offers poor abrasion resistance, which is relatively poor among synthetic fibers.
[0026] Moisture-wicking fabrics are made of moisture-wicking fibers. These fibers typically have a high specific surface area, numerous pores or grooves on their surfaces, and a unique cross-section. Using the capillary effect, these fibers rapidly absorb moisture and perspiration from the skin's surface and transfer them to the outer layers through diffusion. Moisture-wicking fabrics primarily include polyester and nylon. Because polyester is a highly crystalline fiber, its molecular backbone lacks hydrophilic groups, making it hydrophobic and poorly wicking moisture. This results in poor moisture permeability and a stuffy feeling. Furthermore, static electricity can easily accumulate, leading to various problems. The development of moisture-wicking polyester fibers primarily involves physical and chemical modification, or a combination of both.
[0027] By staggering and sewing the warm elastic fabric 41 and the conductive fabric 42, the elastic support layer 4 as a whole can not only have a good warming effect, but also have relatively good breathable and moisture-wicking properties, and can quickly conduct the moisture captured by the internal capture layer 5 to the external diffusion layer 2, so that the human body surface will not feel damp and hot.
[0028] The elastic protective layer 3 is first bonded to the upper surface of the elastic support layer 4 by spraying glue, and then the elastic protective layer 3 is sewn to the elastic support layer 4 by the second elastic thread 7. The lower surface of the elastic support layer 4 is connected to the upper surface of the internal capture layer 5 by hot pressing bonding. The external diffusion layer 2, the elastic protective layer 3, the elastic support layer 4, and the internal capture layer 5 are sewn and fixed by the first elastic thread 6. The elastic protective layer 3 is interfered with by the second elastic thread 7 and is wavy. The second elastic thread 7 is perpendicular to the wave direction. The first elastic thread 6 and the second elastic thread 7 are perpendicular to each other. The first elastic thread 6 and the second elastic thread 7 are perpendicular to each other, so that the fabric has a high tensile strength in both the length and width directions.
[0029] Because the elastic protective layer 3 is wavy, it has many peaks, and the peaks are bonded to the surface of the outer flannel base 21 and the elastic support layer 4. When the fabric body 1 as a whole undergoes elastic deformation, the elastic protective layer 3 will unfold, so that the fabric can still maintain a good warmth-keeping effect when stretched, and the fabric will not be too thin in some areas due to stretching.
[0030] When using the product, the side away from the human body will be subjected to greater tensile force during movement, and its stretching length will also be longer. After long-term use, the outer fabric will be damaged, pilling, or even tearing.
[0031] By providing the elastic protective layer 3, the side of the fabric away from the human body can have a higher yield ability, avoiding damage to the fabric caused by strong stretching, making the fabric more widely applicable and suitable for making products such as sleeping bags.
[0032] Traditional thermal fabrics have poor air permeability when used. Long-term use will cause the human body to feel hot and damp, and even cause acne. Fabrics with good air permeability have poor windproof and thermal insulation properties, affecting their use effect.
[0033] By setting an elastic support layer 4, locally interspersed with warm elastic fabric 41 and conductive fabric 42, the conductive fabric 42 is increased or decreased according to the usage scenario, so that the fabric has a good warming effect while also providing good breathability. Because the area of the conductive fabric 42 is much smaller than the area of the warm elastic fabric 41, it will not cause a large change in internal temperature when air circulates, and is suitable for long-term use.
[0034] When there is moisture inside, the short velvet 52 can quickly capture moisture and conduct it to the inner velvet base 51, which is then conducted to the elastic protective layer 3 through the conductive fabric 42. The elastic protective layer 3 can quickly conduct the moisture to the outer velvet base 21, and finally dissipate it into the air through the long velvet 22, so that the fabric has a very good moisture-wicking ability. The short velvet 52 can quickly capture moisture, and the long velvet 22 can quickly dissipate moisture, so that the user can always stay dry and can be used for a long time.
