[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The breathable and dry fabric of this invention is made by using functional fiber filaments, modified modal fiber filaments, and polyester fiber filaments, processed by air jet deformation method, and then woven on a large circular knitting machine. The resulting breathable and dry fabric has breathability, sweat-wicking properties, softness, and UV resistance. The overall performance of the product is significantly improved, and the water resistance and stability of the product are also significantly enhanced.

[0030] Modified Modal fiber filaments are produced by impregnating Modal fiber filaments with a modifier based on a nanofiber composite homogeneous dispersion. The modifier based on the nanofiber composite homogeneous dispersion is nanocellulose, which is optimized by blending with ethanol and methyltrimethoxysilane. Simultaneously, it is further homogenized using a mesoporous silica-montmorillonite homogeneous dispersion. The mesoporous silica-montmorillonite homogeneous dispersion is made by ball milling mesoporous silica with N,N-dimethylformamide and sodium dodecylaminopropionate to optimize the hydrophobic effect of the mesoporous silica. Furthermore, the raw materials are improved through blending and homogenization. The dispersion of montmorillonite is improved by stirring, while the uniform dispersion of montmorillonite is achieved by using montmorillonite in combination with a uniform dispersion agent. The uniform dispersion agent contains nano-alumina, silane coupling agent KH550, acetone, and sodium alginate solution, which are blended and optimized. The uniform dispersion agent is used to better disperse and improve montmorillonite. The layered structure of montmorillonite is combined with the mesoporous silica system, and the uniform dispersion agent is blended with nano-alumina. At the same time, the interaction of raw materials in the modifier based on nanofiber combined uniform dispersion enhances the functional effects of modal fiber filaments in the system, such as breathability, perspiration wicking, and hydrophobicity.

[0031] The functional fiber filaments are made from polyethylene fiber filaments treated with hydrochloric acid solution, and then ultrasonically improved with a functional liquid. The functional liquid contains silicon carbide, silicon powder, vinyltrimethoxysilane, acetone, and ammonia, which are mixed together. With silicon carbide and silicon powder as the matrix, the system's performance stability and performance coordination are enhanced. In addition, the functional liquid contains vinyltrimethoxysilane and other raw materials that are synergistically formulated. Through the interaction of the raw materials in the functional liquid, the resulting functional fiber filaments strengthen the structural connectivity of the product and further enhance the product's performance.

[0160] From comparative examples 1-12 and example 3, it can be seen that the water contact angle and the static water pressure resistance of the product have a significant deterioration trend when one of the modified modal fiber filament and the functional fiber filament is not added to the product. Only when the modified modal fiber filament and the functional fiber filament of the application are blended and cooperated, the water resistance of the product is the most excellent. At the same time, the performance of the product has a deterioration trend when the modified modal fiber filament and the functional fiber filament prepared by different methods are used, and the performance effect of the product is the most remarkable only when the raw materials and process of the application are used.

[0161] It is apparent to those skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments, and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the application is defined by the appended claims rather than the foregoing description, and it is intended to include all changes falling within the meaning and range of equivalents of the claims.

[0162] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature described. The specification can include implicit combinations of explicitly mentioned features and / or explicit combinations of implicitely mentioned features. Each embodiment depends on the explicit combinations of features and / or the implicit combinations of features made specifically within that embodiment, and each such embodiment can be combined with every other such embodiment to create further embodiments.
