Description

Textile system with adjustable optimal temperature

The present invention relates to a textile system, and more specifically, to a textile system capable of adjusting the optimal temperature.

Traditional cooling and heating products (such as cooling and heating quilts) are made of a combination of materials that are cool on one side and warm on the other side. When the skin touches the material, it feels instantly cool and instantly warm, but it does not have the function of regulating temperature. As a result, after the user uses it for a period of time, the body temperature will cause the contact surface temperature to rise and overheat. On the other hand, the new generation of temperature-regulating textiles may contain phase change materials, but there is no insulation layer to block the external temperature, causing the phase change material to be forced to react to the internal and external temperatures at the same time, and it cannot effectively regulate the internal temperature.

In the existing Republic of China new patent case No. M611490U, a hot and cold dual-purpose quilt structure is disclosed, which includes: a warm fabric inner layer; a cool fabric inner layer, which is not in contact with the warm fabric inner layer; and a quilt body layer, which is composed of cotton or fiber material, and the quilt body layer is stacked and sandwiched between the warm fabric inner layer and the cool fabric inner layer, wherein the warm fabric inner layer is fixed to the quilt body layer by sewing, and the cool fabric inner layer is fixed to the quilt body layer by sewing. The hot and cold dual-purpose quilt structure provided by the invention can achieve the following effects: one side of the quilt has a fast thermal response and a long-lasting warming effect, and the other side of the quilt has a cooling and cooling effect. The hot and cold dual-purpose quilt structure equipped with a sheet set can be directly covered on the human body, with the side of the warm layer or the side of the cool layer facing the human body, so that the human body can quickly feel a comfortable temperature.

The technical field of the previous case is similar to that of this case. In that case, there is no phase change fiber layer as a barrier layer, so it cannot completely lock the heat and cold air between different layers. Therefore, it will become ineffective after long-term use and cannot adjust the temperature. This case uses a phase change fiber layer for isolation, thereby solving the problem.

The optimal temperature adjustable textile system 100 of the present invention can further have the following applications:

1. Natural fibers can be used as the building material of the optimal temperature-adjustable textile structure 100 of the present invention:

By using the two-layer design of the cup body of the traditional thermal insulation equipment as the insulation layer of the present invention, adding the phase change fiber layer in the middle, and calculating the required joule number of the phase change fiber layer, a product that can maintain an adjustable temperature for a long time can be established.

4. Product design and application in extreme environments:

The insulation layer 312 can adjust its thickness according to the external temperature of the use scenario, and the phase change fiber layer 314 can adjust its thickness according to the heat energy demand for internal temperature regulation.

In summary, the present invention selects fibers containing corresponding phase change substances as the temperature regulating layer material through the structural combination design of the insulation layer 312 and the phase change fiber layer 314 according to the temperature requirement of the target effect, and calculates the number of phase change fibers and the number of temperature regulating layers required for the temperature regulating layer according to the temperature regulation requirement of the target effect, and optimizes the combination of the insulation layer, so that the external temperature and the internal temperature can be completely blocked, so that the phase change temperature regulating energy of the phase change fiber layer can be effectively exerted in regulating the internal temperature, ensuring that the optimal temperature can be continuously regulated.
