Technical Field
[0001] The utility model relates to the technical field of textiles, and more specifically to a warm-keeping and heat-storing ultra-light nylon fabric. Background Art
[0002] Nylon fabric is formed by weaving nylon fibers. Nylon fiber is a synthetic fiber with a wide range of uses. Nylon fiber has high structural strength and good wear resistance. Therefore, nylon fabric is a common type of fabric used to make clothing.
[0003] When people wear outdoor clothing for outdoor activities in winter, in order to reduce the cold air that passes through the fabric and contacts the user's body surface, the clothing fabric is usually thicker. However, thicker fabric will affect the convenience of people's activities. However, when the thickness of the fabric is reduced to facilitate people's activities, the warmth retention of the clothing cannot be guaranteed. Therefore, a structure is provided to solve the problem of thicker warmth retention fabric. Utility Model Content

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] The warm and thermal ultra-light nylon fabric, such as Figure 1 and Figure 2As shown, it includes an inner layer 1 and an outer layer 2 which are fixedly connected to each other. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine. The setting of the double-layer fabric increases the thickness of the fabric, reduces the convection of cold air and hot air on both sides of the fabric, and ensures the warmth retention of the fabric. A plurality of thermal insulation sheets 3 are fixedly connected to the side of the outer layer 2 close to the inner layer 1. A plurality of thermal insulation grooves 4 are provided in the thermal insulation sheets 3. The thermal insulation sheets 3 include a plurality of ceramic powders. The thermal insulation sheets 3 are formed by a ceramic powder printing process on the side of the outer layer 2 close to the inner layer 1. The pores between the internal fibers of the outer layer 2 are reduced by adding ceramic powder, and the passage for the cold air inside the outer layer 2 to enter is reduced. The characteristics of the ceramic powder are used to ensure the warmth retention and heat storage performance of the fabric. The setting of the thermal insulation grooves 4 increases the amount of air inside the outer layer 2. The thermal conductivity of the air is poor, thereby reducing the contact between the external cold air passing through the inner layer 1 and the user's body surface, thereby ensuring the warmth retention and fluffy effect of the fabric when it is used.
[0019] like Figure 1 and Figure 2 As shown, a contact piece 5 with the same relative position as the thermal sheet 3 is fixedly connected to one side of the inner layer 1 close to the outer layer 2, and the width of the contact piece 5 is greater than that of the thermal sheet 3. The setting of the contact piece 5, on the one hand, increases the thickness of the inner layer 1 and reduces the convection of hot and cold air on both sides of the fabric. On the other hand, the setting of the contact piece 5 allows a stable channel for external air to flow through to exist between the inner layer 1 and the outer layer 2. The setting of the channel increases the amount of still air retained between the inner layer 1 and the outer layer 2. Since the thermal conductivity of still air is poor, the cold air that passes through the inner layer 1 and contacts the user's body surface is reduced, thereby enhancing the overall warmth and heat storage performance of the structure.
[0020] like Figure 1 and Figure 2 As shown, a plurality of thermal fleeces 6 are fixedly connected to one side of the contact piece 5 close to the outer layer 2, and the plurality of thermal fleeces 6 extend into the thermal groove 4. The contact piece 5 is placed in a napping machine for napping to form the thermal fleece 6. The provision of the thermal fleece 6 further increases the thickness of the inner layer 1. The provision of the thermal fleece 6 increases the amount of external air retained in the thermal piece 3, so that the fabric can be better deformed during use, thereby ensuring the softness and fluffiness of the fabric. The contact piece 5 is calendered by a calender to ensure the anti-velvet effect of the fabric when it is used. The calendering process is used to reduce the situation where various additives inside the fabric drill out of the fabric, thereby ensuring the stability of the structure when it is used.
[0021] like Figure 1 and Figure 3As shown, the outer layer 2 is woven by the warm yarn 7, and the count of the warm yarn 7 is 10. The diameter of the warm yarn 7 is reduced by setting the count of the warm yarn 7. The outer layer 2 woven by the warm yarn 7 with a smaller diameter is thinner, so that the fabric can ensure warmth while taking into account lightness. The warm yarn 7 includes a warm yarn core 8 and a warm covering yarn 9. The warm yarn core 8 and the warm covering yarn 9 are processed by a spindle spinning process to form the warm yarn 7. The warm yarn core 8 is twisted by a nylon fiber 1 through a twisting machine. The nylon fiber 1 has good structural strength and shape retention. The durability of the entire structure is enhanced by the setting of the nylon fiber 1. The warm covering yarn 9 is twisted by a nylon shaped fiber with a hollow circular cross-section through a twisting machine. The setting of the nylon shaped fiber increases the air content inside the warm yarn 7 and enhances the warmth of the entire structure.
[0022] like Figure 1 and Figure 2 As shown, the contact sheet 5 is integrally formed with the inner layer 1, and the inner layer 1 is configured as a convex stripe structure, the ground structure of the convex stripe structure is the inner layer 1, and the surface structure of the convex stripe structure is the contact sheet 5. Through the configuration of the convex stripe structure, the inner layer 1 can naturally form a contact sheet 5 on its surface during weaving, thereby ensuring the stability of the structure during manufacturing and use.
[0023] like Figure 1 and Figure 4 As shown, the inner layer 1 is woven by composite yarn 10, and the composite yarn 10 includes a composite yarn core 11 and a composite covering yarn 12 spirally wound on the outside thereof. The composite yarn core 11 and the composite covering yarn 12 are processed by a spindle spinning process to form the composite yarn 10. The composite yarn core 11 is twisted by three-pass nylon fiber twisting machine, and the light weight of three-pass nylon fiber is utilized to ensure the lightness and comfort of the inner layer 1 and the overall fabric during use. The composite covering yarn 12 is twisted by two-pass nylon fiber twisting machine.
[0024] like Figure 1-Figure 4 As shown, when the fabric needs to be made, the composite yarn 10 is put into a shuttle loom and woven into an inner layer 1 and a plurality of contact sheets 5 through a convex strip weaving method, the inner layer 1 is put into a napping machine to form a plurality of thermal fleeces 6 on the surface of the contact sheets 5, the thermal yarn 7 is put into a shuttle loom and woven into an outer layer 2, and a thermal sheet 3 and a thermal groove 4 are formed on one side of the outer layer 2 through a ceramic powder printing process, and finally the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
