Description
Technical Field
The application relates to the field of fabrics, in particular to a heat dissipation woven fabric and a preparation method thereof.
Background
Common fabrics in the market are mainly divided into knitted fabrics and woven fabrics. The knitted fabric is formed by bending yarns into loops by using a knitting needle and mutually interlooping the loops. Larger gaps are formed among the yarns of the knitted fabric, so that the knitted fabric is high in air permeability and good in heat dissipation performance. The woven fabric is formed by interlacing warp and weft yarns in a picking mode of a weaving machine. The fabric has the advantages of firmness, stiffness, smoothness, difficult deformation and the like because the weaving method is staggered in warp and weft.
However, the weaving method with staggered warps and wefts leads to smaller gaps among the spun yarns and poorer air permeability, thus leading to low heat conduction efficiency. Therefore, clothes made of the woven fabric are poor in heat dissipation performance when worn in summer and poor in wearing comfort.

Performance test
Test 1: test sample for testing heat dissipation performance of fabric: referring to the standard in GB/T11048 measurement of thermal resistance and wet resistance under the steady state condition of the physiological comfort of the textile, 3 samples of 30cm multiplied by 30cm are cut from the fabric prepared in each group of examples or comparative examples, and the samples are flat and have no wrinkles.
The test method comprises the following steps: referring to a testing device of a 'flat plate constant temperature difference heat dissipation method' in a method A of GB/T11048-1989, a test sample is covered on a test board, the temperature of the test board, a bottom plate and a surrounding protective plate is controlled to be 36 ℃ by electric heating, and the constant temperature is kept in a power-on and power-off mode, so that the heat of the test board can be dissipated only in the direction of the test sample. In order to measure the heating time required for keeping the test plate at a constant temperature for a certain period of time, the heat-insulating rate of the sample was calculated, and the lower the heat-insulating rate, the better the heat-dissipating performance, and the test results are shown in table 2.
TABLE 2 Fabric Heat dissipation Performance test results
And (3) analyzing test results:
(1) as can be seen by combining examples 1 to 14 and comparative examples 1 to 3 with Table 2, nano Al is used2O3/TiO2The composite powder can obviously improve the heat dissipation of the woven fabric. The reason for this may be that, on the one hand, nano Al2O3/TiO2The heat conductivity coefficient of the composite powder is obviously higher than that of polyester fibers, and the composite powder is distributed in the polyester yarns to improve the heat conduction efficiency of spinning, so that the heat diffusion is accelerated, and the heat dissipation performance of the woven fabric made of the polyester yarns is improved. On the other hand, nano Al2O3/TiO2The composite powder can absorb heat emitted by a human body outwards (the body temperature of the human body is simulated by electrically heating the bottom plate and the protective plate in the test), and then the heat is emitted outwards in an infrared mode, so that the heat dissipation effect of the woven fabric is improved.
(2) As can be seen from the combination of examples 1 and 5 to 6 and table 2, the heat dissipation performance of the woven fabric is improved by using hydrotalcite in this experiment. The reason for this is probably that the test cannot simulate the contact state of human sweat and the fabric, so that the influence of the moisture absorption effect of the hydrotalcite on the heat dissipation effect of the woven fabric cannot be reflected.
(3) When example 1 and examples 5 to 6 were combined and Table 2 was repeated, it was found that Na was contained in different concentrations2CO3The prepared mixed alkali solution has certain influence on the heat dissipation of the woven fabric. The reason for this may be that Na2CO3Influencing CO in hydrotalcite interlayer structures3 2-Content of anions, thereby affecting CO during melt extrusion2The release amount of the gas further influences the structures such as the number and the aperture of micropores in the polyester yarn structure, and finally influences the air permeability, the moisture absorption and the heat dissipation of the woven fabric.
Test 2: fabric moisture absorption performance test samples: 5 samples of 10cm x 10cm are cut from the fabric obtained in each example or comparative example, according to the standard of the GB/T21655.1 evaluation of quick moisture absorption and drying of textiles.
The test method comprises the following steps: referring to the test method in GB/T21655.1 'evaluation on moisture absorption quick drying of textiles', 0.5% orange red potassium heavy complex solution is gently dropped on a sample by about 0.2mL of the potassium heavy complex solution, the spreading condition of the water drop is carefully observed, the time required for the water drop to contact the surface of the sample until the water drop is completely spread is recorded, and the test results are shown in Table 3.
In addition, the test sample which finishes the water drop diffusion test is immediately weighed according to the test method in GB/T21655.1 'evaluation on moisture absorption and quick drying of textiles', and then is hung in the standard atmosphere, and the test sample is naturally and flatly hung vertically; the mass was weighed every 3min to the nearest 0.001 g. And ending the test until the change rate of the mass weighed twice continuously does not exceed 1%, wherein the test results are shown in Table 3.
Table 3 fabric moisture absorption test results
And (3) analyzing test results:
(1) by combining the examples 1 and 5-6 and the table 3, it can be seen that the hydrotalcite prepared by the method of the present application can significantly improve the moisture absorption of the woven fabric. The reason for this is that there are water molecules in the hydrotalcite interlayer structure, and in the process of melt blending of hydrotalcite and PET chips, the water molecules in the interlayer structure are released, and after spinning into polyester filaments, hydrotalcite is dispersed in the polyester filaments. It can absorb the sweat on human surface for during the hydrone reinserts interlaminar structure, consequently can improve the diffusion and the evaporation of hydrone, thereby improve the hygroscopicity of tatting surface fabric, finally through the improvement of evaporation rate, be favorable to the improvement of tatting surface fabric thermal diffusivity.
(2) As can be seen by combining examples 1 and 5 to 6 with Table 3, the use of Na in different concentrations2CO3The prepared mixed alkali solution has certain influence on the heat dissipation of the woven fabric. The reason for this may be that Na2CO3The dosage will affect the CO in the hydrotalcite interlayer structure3 2-Content of anions, thereby affecting CO during melt extrusion2Release of gas, and thus shadowThe quantity of micropores formed in the polyester yarn structure, the pore size and other structural forms are affected, and evaporation and diffusion of moisture are finally influenced.
(3) By combining the examples 1, 12 to 14 and the comparative examples 1 to 2 and combining the table 3, it can be seen that the heat dissipation performance of the woven fabric can be remarkably improved by using the nano Al2O3/TiO2 composite powder and ultraviolet irradiation in the experiment, and the combined effect of the two is more excellent. The reason for this may be that the nano Al2O3/TiO2 composite powder has relatively excellent ultraviolet light absorption rate, and can absorb ultraviolet light to catalyze the polyester on the surface of the woven fabric to oxidize to form hydrophilic groups, so as to improve the water absorption performance of the woven fabric, and finally improve the heat dissipation performance of the woven fabric.
In addition, the irradiation time is shortened, sufficient hydrophilic groups cannot be formed on the surface of the woven fabric, the irradiation time is prolonged, the water absorption of the fabric can be improved to a certain degree, and the color and the intensity of the woven fabric are affected.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
