Abstract

The invention discloses a moisture-absorption quick-dry antibacterial fabric and a preparation method thereof, and relates to the technical field of textiles. The preparation method comprises the following steps: firstly, preparing porous nano titanium dioxide, crosslinking the porous nano titanium dioxide and polyester by using 1, 2, 3, 4-butanetetracarboxylic acid as a crosslinking agent to obtain TiO2 modified polyester, performing electrostatic spinning on the TiO2 modified polyester to obtain TiO2 modified polyester fibers, and performing double-layer weaving on the TiO2 modified polyester fibers and natural fiber blended yarns to obtain the moisture-absorbing quick-drying antibacterial fabric. According to the invention, porous nano titanium dioxide is grafted with hydroxyl-terminated polyester, so that the fabric has the characteristics of excellent moisture absorption, quick drying and antibacterial property.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a moisture-absorbing and quick-drying antibacterial fabric and a preparation method thereof. Background technique [0002] The human body will secrete a lot of sweat when exercising. Natural fibers (cotton, hemp) have good moisture absorption and air permeability, and provide good thermal and humidity comfort for the wearer when the human body sweats. However, when the human body sweats a lot or When in contact with liquid, the natural fibers absorb moisture and expand, the gaps between the fibers are reduced, and the water transfer rate is reduced, resulting in a decrease in the air permeability of the clothes and adhesion to the skin surface, causing the human body to feel cold and wet. Synthetic fibers have excellent moisture-wicking and quick-drying properties, but synthetic fiber clothing has poor moisture absorption and water absorption properties. The sweat on the surface...
