Problems solved by technology

However, the commonly used antibacterial agents are not resistant to water washing, resulting in unsustainable antibacterial activity; in addition, the use of these antibacterial agents to modify the fabric often affects the wearability of the fabric, such as poor moisture permeability and air permeability, mechanical properties Variation, etc.
[0004] However, the existing antibacterial fabrics cannot meet people's needs in terms of tensile strength, wear resistance and air permeability. Therefore, it is particularly important to improve the properties of fabrics while improving their antibacterial properties.

Abstract

The invention discloses a high-strength nano-composite antibacterial fabric and a preparation method thereof. The high-strength nano-composite antibacterial fabric comprises an antibacterial reinforcing layer and a modified fiber layer bonded to the antibacterial reinforcing layer; and according to the modified fiber layer, by drafting and twisting modified fibers and breathable fibers, blended yarns are prepared, and then the blended yarns are woven by adopting a circular knitting machine weft knitting weaving method to form the high-strength nano composite antibacterial fabric. The modified fibers and the breathable fibers are prepared, so that the tensile strength, the abrasion resistance and the breathability of the antibacterial fabric are greatly improved. The problem that an existing antibacterial fabric cannot meet the requirements of people in the aspects of tensile strength, abrasion resistance, breathability and the like is solved, and compared with the mode that modified fibers and breathable fibers are independently used at the same time, a better effect can be achieved, and synergistic interaction is generated.

Description

technical field [0001] The invention relates to an antibacterial fabric, in particular to a high-strength nano-composite antibacterial fabric and a preparation method thereof. Background technique [0002] Fabrics are very popular and used by consumers, but the current fabrics have disadvantages such as poor moisture absorption and air permeability, uncomfortable wearing, and poor friction resistance; and man-made fiber fabrics are improperly used during use, or improperly washed during washing , will cause man-made fiber fabrics to be damaged in different degrees. [0003] In order to inhibit the growth of bacteria, dust mites, etc., antibacterial modification of fabrics is a common method. However, the commonly used antibacterial agents are not resistant to water washing, resulting in unsustainable antibacterial activity; in addition, the use of these antibacterial agents to modify the fabric often affects the wearability of the fabric, such as poor moisture permeability ...
