[0058] Comparative Example 3
[0059] This comparative example adopts the same implementation method as Example 1, with the difference being that the modified volcanic particles do not include tourmaline powder and mica powder.
[0060] Comparative Example 4
[0061] This comparative example adopts the same implementation method as Example 1, with the difference being that the preparation method of the modified volcanic particles is as follows: 55 - 65 parts of volcanic particles and 2 - 6 parts of pore-forming agent are mixed, and after mixing, they are washed with water and dried to obtain porous volcanic particles; the porous volcanic particles are mixed with 5 - 10 parts of tourmaline powder and then taken out to obtain semi-finished modified volcanic particles, and subsequently, the semi-finished modified volcanic particles are mixed with 15 parts of mica powder, 10 parts of styrene-acrylic emulsion, and 15 parts of water to obtain modified volcanic particles.
[0062] Performance test:
[0063] Fabric samples are prepared respectively according to the methods of the above Examples 1 - 3 and Comparative Examples 1 - 4, and seven groups of samples with an area of 400 cm 2 are obtained. The following performance tests are carried out on the seven groups of samples respectively:
[0064] A: Thermal insulation performance: Refer to "GB / T 11048 - 1989 Test Method for Thermal Insulation Performance of Textiles" (Level Ⅰ - Ⅴ, Level Ⅰ has the best thermal insulation performance);
[0065] B: Waterproof performance: Refer to the standard number AATCC 35 - 2000, and the standard name is Waterproof Test: Rain Experiment. Level 1 - 5, Level 1 means completely wet;
[0066] C: Performance after washing: Refer to the international standard ASTM D 1518—2014 "Test Method for Thermal Resistance of Cotton Bats System (Hot Plate Method)" (applicable to cotton bats and multi-layer cotton bats / fabric assemblies that have thermal conductivity and range between 0.1 W / m2·K and 1.5 W / m2·K, and the specimen thickness does not exceed 50 mm);
[0067] D: Elongation at break performance: GB / T 3923.1~2013 "Determination of Tensile Properties of Textiles Fabrics";
[0068] The performance test results are as follows in the table:
[0069] ;
[0070] As can be seen from the data in the above table, the fabrics prepared in Examples 1-3 of the present invention have excellent thermal insulation, waterproof, wash-resistant and tensile properties. From the data of Comparative Example 1, it can be seen that the fabric prepared in Comparative Example 1 has significantly decreased in thermal insulation performance, wash-resistant performance and elongation at break compared with Example 1. This is because the nano-alumina powder not only improves the thermal insulation performance of the fabric, but also improves the toughness of the fabric, making the fabric less prone to wrinkling, so that the volcanic particle layer can more stably provide thermal insulation; from the data of Comparative Example 2, it can be seen that the fabric prepared in Comparative Example 2 uses ordinary volcanic particles, and its thermal insulation performance is worse than that of Example 1. At the same time, as the number of washing times increases, the thermal insulation performance of the fabric prepared in Comparative Example 2 decreases significantly. This is because the modified volcanic particles not only improve the overall thermal insulation performance of the fabric, but also have a high adhesion to the fabric layer, and the volcanic particles are not easily detached or damaged, and can ensure the thermal insulation performance of the fabric for a long time to improve the wind resistance of the fabric. At the same time, the combination of the modified volcanic particles and the fabric layer also effectively improves the tensile performance of the fabric layer; from the data of Comparative Example 3, it can be seen that the fabric prepared in Comparative Example 3 has poor thermal insulation performance and elongation at break. This is because the tourmaline powder and mica powder in the modified volcanic particles not only improve the connection strength between the fabric layer and the volcanic particle layer, but also improve the thermal insulation performance and elongation at break of the inner layer of the obtained volcanic rock particles; from the data of Comparative Example 3, it can be seen that as the number of washing times of the fabric prepared in Comparative Example 3 increases, its thermal insulation performance decreases significantly. This is because after obtaining the porous volcanic particles, it is directly mixed with mica powder, styrene-acrylic emulsion and water, while in Example 1, mica powder, styrene-acrylic emulsion and water are prepared into a spraying liquid, and the spraying liquid is sprayed on the surface of the semi-finished modified volcanic particles by the thermal atomization spraying method. This method enables the spraying liquid to form a film with high adhesion on the porous volcanic particles, on the one hand, improving the adhesion between the subsequent modified volcanic particles and the fabric layer, on the other hand, enabling some tourmaline powder to be wrapped in the pores of the porous volcanic particles, enhancing the thermal insulation performance, and further containing mica powder in the spraying liquid, enhancing the strength of the porous volcanic particles, making them not easily broken, and strengthening the tensile performance of the volcanic rock fabric.
[0071] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
