Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of thermal fabric preparation, and particularly relates to a bionic mineral thermal printing thermal fabric and a preparation method thereof. BACKGROUND

[0002] Thermal insulation is an important principle of fabric warmth. Fabric can reduce heat loss through the design of the thermal insulation layer, thereby providing better warmth. The thermal insulation layer is generally composed of multiple layers of fabric, which can be filled with some thermal insulation materials such as down, cotton, etc. These materials can form an air layer to reduce heat conduction, thereby improving the thermal insulation effect. At the same time, the design of the thermal insulation layer also needs to consider the air permeability to avoid excessive sealing and moisture accumulation, which affects the warmth.

[0003] There are various thermal fabrics in the prior art, which can all produce good thermal insulation effect, but they are based on dry use conditions and can be insulated. When the user sweats a lot, the fabric gets wet, and when the fabric gets wet, its thermal insulation effect decreases sharply. SUMMARY

In the infrared wave band, the reflectivity of aluminum is about 0.8 to 0.9, that is, aluminum material can better reflect infrared light and absorb less energy. Aluminum can effectively reflect human body heat and prevent heat loss, and build a thermal energy circulation microclimate between the garment and the skin

[0012] S6: Spraying waterproof agent on the surface of the finished intimate layer to obtain fabric two, the waterproof agent not only makes the waterproof performance of the intimate layer better, but also reinforces the aluminum powder in the holes of the intimate layer, avoiding the rapid falling of the aluminum powder in the use process and reducing the heat preservation effect of the fabric;

[0013] S7: Compounding fabric two and the water absorption and quick drying layer to obtain the thermal insulation fabric;

[0014] S8: Printing on the surface of the thermal insulation fabric to form a biomimetic mineral thermal effect and increase the visual effect of thermal insulation.

[0015] Preferably, the mass ratio of polyester fiber, polypropylene fiber and bamboo fiber in S1 is 5:1:1, and the polyester fiber has good water absorption and quick drying performance.

[0016] Preferably, the mass ratio of polyester fiber and acrylic fiber in S2 is 1:0.4-0.5.

[0017] Preferably, the modification method in S4 comprises the following steps:

[0018] a. Prepare a sodium hydroxide solution with a mass concentration of 12%-17%, then add the semi-finished intimate layer into the solution, heat to 50 DEG C and keep for 1h;

[0019] b. Take out the semi-finished intimate layer, wash with deionized water, and dry after drying.

[0020] Preferably, the waterproof agent in S5 is one or more of silane waterproof agent, fluorocarbon waterproof agent and polytetrafluoroethylene waterproof agent.

[0021] Preferably, the compounding method in S6 is as follows: after the water absorption and quick drying layer and fabric two are overlapped together, the polyester fiber yarn is used to sew the water absorption and quick drying layer and fabric two together, multiple rows of sewing, the spacing between the sewing lines is 10-20cm, and the polyester fiber yarn has good water absorption and quick drying performance, which can quickly transfer sweat to the outside water absorption and quick drying layer when it contacts the human body, thereby improving the sweat rate of the human body.

[0022] A biomimetic mineral thermal printing thermal insulation fabric is prepared by the above preparation method.

[0023] The beneficial effects of the present application are:

[0024] The present application composites the non-water-absorbing close-to-body layer and the water-absorbing and quick-drying outer layer to obtain the thermal fabric, so that when the human body sweats a lot, the sweat can be absorbed by the water-absorbing and quick-drying layer through the close-to-body layer, so that the human body remains dry, and the thermal energy of the human body is reflected by the metal component on the fabric, so that the thermal energy is kept between the outer layer and the skin, thereby reducing the heat loss of the human body, and a thermal energy circulation space is constructed between the clothing and the skin.

[0105] Blank group

[0106] Compared with Example 3, the blank group is an ordinary thermal insulation fabric without treatment.

[0107] In order to verify the product performance of the present application, the following product thermal insulation performance test is carried out, and the details are as follows:

[0108] The thermal insulation fabrics of Examples 1-3 and Comparative Examples 1-3 are prepared by the method and are cut into the same size, and an ordinary thermal insulation fabric of the same size is prepared, 10 pieces are taken from each different fabric, and each fabric is attached to the surface of a human body model sprayed with water, the initial temperature of the human body model is 36.5℃, after 5 minutes, the temperature of the surface of the human body model is measured by using a thermometer, and the humidity of the surface of the human body model is measured by using a hygrometer, and the average value is taken, and the results are shown in Table 1.

[0109] Table 1: test results

[0110]

[0111]

[0112] As can be seen from Table 1, the thermal insulation fabric prepared by the preparation method in the present application has better thermal insulation effect than the ordinary fabric, and can absorb the sweat of the human body faster and maintain the normal temperature of the human body.

[0113] In the comparative example 1, no aluminum powder is added, so that the heat generated by the human body is dissipated to the outside through the fabric, thereby reducing the body temperature of the human body.

[0114] In the comparative example 2, the close-to-body layer is not waterproof treated, and the close-to-body layer absorbs the sweat of the human body, so that the sweat of the human body is not discharged in time, the sweat is adsorbed on the surface of the human body, and the heat of the human body is reduced through evaporation absorption, thereby reducing the temperature of the human body.

[0115] In the comparative example 3, the thermal insulation fabric is not sewn by using the easily water-absorbing yarn, which affects the timely absorption of the sweat by the water-absorbing and quick-drying layer of the outer layer, causes the residual of the sweat, and thus affects the thermal insulation performance of the fabric.

[0116] In the comparative example 4, the close-to-body layer is not modified, the storage amount of the aluminum powder in the close-to-body layer is reduced, the reflection ability of the close-to-body layer to the heat of the human body is reduced, and thus the thermal insulation performance of the fabric is affected.

[0117] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
