Description

Technical Field

[0001] The present application relates to the technical field of fabric structures, and in particular to a multifunctional fabric. Background Art

[0002] Fabrics are mostly made into clothing to cover the skin and keep warm. There are many kinds of materials for making fabrics, which can be selected and matched according to needs. For example, if you want the clothes to have a better warming effect, you need to fill the interlayer of the fabric with cotton or down materials, which will make the clothes bloated, and wearing bloated clothes will affect the body's activities; on the other hand, common fabrics, if not waterproofed, the cotton in the fabric is very easy to absorb water. If you wear cotton clothes in the rainforest, once it rains, the warm cotton clothes will quickly become heat-absorbing water bags. Although down jackets perform better than cotton clothes in this regard, their thermal insulation performance will also be significantly reduced if they are also caught in the rain. Summary of the Invention

[0003] The purpose of this application is to provide a light and thin fabric with excellent rainproof and heat-insulating properties.

[0004] To achieve the above objectives, the present application provides a multifunctional fabric: comprising a first fabric layer and a second fabric layer, a polyester film layer is arranged between the first fabric layer and the second fabric layer, and a reflective layer is provided on the surface of the polyester film layer facing the first fabric layer or the second fabric layer, which is used to reflect heat radiation, improve heat utilization, and thus achieve a warming effect.

[0005] As a preference, the reflective layer provided on the surface of the polyester film layer is a tinfoil film layer, which is simple to manufacture and low in cost.

[0006] As a preference, the tinfoil film layer is located between the polyester film layer and the second fabric layer, closer to the outside of the entire fabric.

[0007] Preferably, the first fabric layer and the polyester film layer are sewn together by cotton thread, and the sewing threads are distributed at the edges of the first fabric layer and the polyester film layer and the area within the edges to ensure that the polyester film layer and the first fabric layer are firmly connected to avoid delamination.

[0008] As a preferred embodiment, the tinfoil film layer is adhered to the polyester film layer and the second fabric layer by JL-6218 metal-bonding special glue. JL-6218 metal-bonding special glue provides elastic protection to the tinfoil film layer, which can effectively reduce damage to the tinfoil film layer.

[0009] As a preferred embodiment, the first fabric layer serves as the inner fabric, is suitable for direct contact with the skin, and has a thickness in the range of 1 to 1.7 mm; the thickness of the polyester film layer is in the range of 0.2 to 0.3 mm; the thickness of the tinfoil film layer is in the range of 0.01 to 0.02 mm; the second fabric layer serves as the outer fabric, and has a thickness in the range of 1 to 2.5 mm. The thickness of each layer of material is reasonably selected to ensure that the function of each layer is fully reflected.

[0010] As a preference, the first fabric layer is made of pure cotton material, and the second fabric layer is made of polyester material, which has good dimensional stability and is easy to wash and quick to dry.

[0011] As a preference, the first fabric layer is made of silk material, and the second fabric layer is made of cotton material, both of which have excellent wear resistance.

[0012] As another preference, the reflective layer provided on the surface of the polyester film layer is a nano-scale conductive particle coating, and the nano-scale conductive particles are made of metallic aluminum material, which can form a dense oxide film with good stability.

[0013] Further preferably, both surfaces of the polyester film layer are provided with a reflective layer, and the reflective layer of the polyester film layer is connected to the first fabric layer and the second fabric layer through JL-6218 metal-specific glue. JL-6218 metal-specific glue provides an elastic buffering effect, reducing the probability of the reflective layer being scratched.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) By placing a polyester film with a reflective layer between the fabrics, the cotton or down used for insulation can be replaced. The polyester film with a reflective layer can achieve the same insulation effect as cotton and down through reflection and heat insulation. In addition, the fabric is lighter and thinner, and the clothes made of it are not bloated and will not affect the appearance and overall shape of the clothes.

[0016] (2) The combination of the polyester film layer and the dense reflective layer inside the fabric makes the fabric have good waterproof properties and can be worn as a raincoat on rainy days; and the elastic adhesive between the layers of the fabric makes the shape of the entire fabric more stable and less prone to wrinkles.

For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0023] like Figure 1 The multifunctional fabric shown includes a first fabric layer 1 and a second fabric layer 4. The first fabric layer 1 and the second fabric layer 4 are the two parts with the largest thickness in the entire fabric. Both are made of common chemical fibers, that is, natural polymer compounds or synthetic polymer compounds as raw materials. The first fabric layer 1 is usually used as the inner layer of the fabric, so it needs to have good skin-friendliness. It is generally made of pure cotton or silk materials. Direct contact with the skin can absorb sweat evaporated from the skin, which is conducive to keeping the skin dry and more comfortable to the touch. The thickness of the first fabric layer 1 in a flat and unstressed state is generally in the range of 1 to 1.7 mm; while the second fabric layer 4 needs to be used as the outer layer of the fabric, so it needs to have good wear resistance. It is generally made of polyester or cotton materials. The second fabric layer 4 made of synthetic fibers also has the characteristics of wrinkle resistance, low shrinkage rate, and high color fastness, making the second fabric layer 4 very durable and easy to maintain in daily use. The thickness of the second fabric layer 4 in a flat and unstressed state is generally in the range of 1 to 2.5 mm.

[0024] A polyester film layer 2 is provided between the first fabric layer 1 and the second fabric layer 4. Due to the good thermal insulation performance of the polyester film, the cold-proof and heat-insulating properties of the entire fabric can be improved to a certain extent. In addition, the polyester film has excellent waterproof and tensile properties. Even if it is made very thin, its waterproofness and tensile strength are not affected. Therefore, the thickness of the polyester film layer 2 is generally within the range of 0.2 to 0.3 mm, which is very light and thin. Therefore, clothing made of this fabric is soft and not bloated, and its warmth retention performance is not inferior to that of cotton clothes that are dozens of times thicker. In order to further improve the thermal insulation performance of the entire fabric, a reflective layer is also provided on the surface of the polyester film layer 2 facing the first fabric layer 1 or the second fabric layer 4 to reflect heat radiation, thereby reducing heat loss and improving heat utilization. The provision of the reflective layer can be roughly divided into two ways, as follows:

[0025] The first method is to make the reflective layer set on the surface of the polyester film layer 2 a tinfoil film layer 3. The tinfoil film layer 3 and the polyester film layer 2 are processed and formed separately, and the two are formed independently of each other. The thickness of the tinfoil film layer 3 is generally in the range of 0.01 to 0.02 mm. The tinfoil film layer 3 is thinner than the polyester film layer 2, so as to ensure the softness of the entire fabric. Although the tinfoil film is made of metal material with high thermal conductivity, the improvement of the thermal insulation performance is not obvious, but the surface of the tinfoil film is smooth and the reflectivity of the heat radiation generated by the human body is high, which can effectively improve the thermal insulation performance of the fabric; since the tinfoil film layer 3 is very thin, two layers can be set, one on each side of the tinfoil film layer 3, but usually only one layer is needed, and the thermal insulation performance of the fabric is high enough. In this example, this layer of tinfoil film layer 3 is located between the polyester film layer 2 and the second fabric layer 4. Since the polyester film has good elasticity and toughness, the first fabric layer 1 and the polyester film layer 2 are sewn together with cotton thread, and the suture line is The first fabric layer 1 and the polyester film layer 2 are placed on the edge and the inner part of the edge, so that the first fabric layer 1 and the polyester film layer 2 are tightly attached and not delaminated. After the polyester film layer 2 is penetrated by the sewing needle, many pinholes will be generated, and the waterproof performance will be reduced. Then the tinfoil film layer 3 is adhered to the polyester film layer 2 through the JL-6218 metal-bonding special glue. The JL-6218 metal-bonding special glue has the characteristics of easy curing, high bonding strength, high elasticity, water resistance, acid and alkali resistance, strong anti-aging performance and film softness. The tinfoil film layer 3 is also bonded to the second fabric layer 4 by the JL-6218 metal-bonding special glue. Since the uncured JL-6218 metal-bonding special glue can penetrate into the limiting gap of the second fabric layer 4, the JL-6218 metal-bonding special glue only needs to be evenly applied in a thin layer for stable adhesion.

[0026] The second method is to make the reflective layer set on the surface of the polyester film layer 2 a nano-scale conductive particle coating. The nano-scale conductive particle coating cannot form an independent layer like the tinfoil film layer 3, but needs to be attached to the surface of the polyester film layer 2. It is a layered structure produced by spraying on the surface of the polyester film layer 2. Nano-scale conductive particles are generally made of metal aluminum material. Metal aluminum can react with oxygen in the air to produce a dense oxide film with good corrosion resistance and reflective properties. Therefore, even if the nano-scale conductive particle coating is thinner than the tinfoil film, its performance is not inferior to the tinfoil film layer 3 structure used in the first method. The difference between the two methods is that in the existing technology, the production process and the coating equipment used in the method of using nano-scale conductive particle coating are relatively complicated, and the cost is relatively high; while in the first method of using tinfoil film layer 3, the process is much simpler, which effectively reduces the production cost.

[0027] On the other hand, due to the second method, there is no tinfoil film layer 3 between the polyester film layer 2 and the two fabric layers, so the two surfaces of the polyester film layer 2 are directly facing the two fabric layers. Therefore, the two surfaces of the polyester film layer 2 are sprayed with a reflective layer made of nano-scale conductive particles, and the reflective layer of the polyester film layer 2 is connected to the first fabric layer 1 and the second fabric layer 4 through JL-6218 metal-specific glue. Since the nano-scale conductive particle coating is very thin and the cured JL-6218 metal-specific glue has high elasticity and good softness, the double-layer nano-scale conductive particle coating has almost no effect on the softness of the entire fabric. On the contrary, the addition of JL-6218 metal-specific glue makes the entire fabric have better elastic recovery ability, a more stable shape, and is not prone to wrinkles like a single piece of fabric layer.

[0028] Working Principle: This multifunctional fabric can be made into clothing or blankets. The polyester film with a reflective layer can effectively keep warm and protect against cold. The material is light and thin, with strong tensile strength. Clothing filled with polyester film will not be particularly bloated, and will not have any impact on the appearance and overall shape of the clothing. The weight ratio is relatively small and it also has good waterproof effect. Clothing made of this fabric has the functions of both cotton-padded clothes and raincoats. The inner and outer fabrics are made of different materials and are easy to distinguish. The lining is comfortable to the touch, and the outer fabric is beautiful and wear-resistant, taking into account both practicality and user experience.

[0029] When a user wears clothing made of this fabric or covers themselves with a blanket made of this fabric, the heat radiation generated by the human body will be reflected back by the reflective layer on the surface of the polyester film layer 2, heating the air between the fabric and the body, keeping the human body warm. In addition, the fabric layer and the polyester film layer 2 themselves have low heat conduction efficiency, which effectively blocks the conduction of heat outward. Therefore, even though this fabric is very light and thin, it can provide a warmth-keeping effect that is no less than that of cotton-padded clothes and down jackets in cold environments.

[0030] When the user is outdoors, the dense polyester film layer 2 and its reflective layer can also provide protection from wind and rain. Moreover, the clothing made of this fabric is light and portable, and the wearer can move more flexibly after wearing it. Compared with bulky cotton-padded clothes, it is more convenient for the wearer to move around. Therefore, the fabric is very suitable for the production of military outdoor clothing.

[0031] The reflective layer inside the fabric can not only reflect the heat radiation from the human body inside to keep warm, but also reflect the natural environment radiation outside to a certain extent, which has a good sunshade and sun protection effect.
