Abstract

The invention discloses a zinc oxide nanorod functional cotton fiber and a preparation method thereof. The preparation method sequentially comprises the following four steps: cotton fiber anionization, BSA modification of anionized cotton fibers, zinc oxide nanorod modification of cotton fibers and BSA coating. According to the method disclosed by the invention, the zinc oxide nanorod coats the middle of BSA, so that the adhesive ability of the zinc oxide nanorod is greatly improved. The zinc oxide nanorod modified cotton fiber has excellent antibacterial property, ultraviolet resistance, photocatalysis, super-hydrophobic property, crease resistance and washing fastness.

Description

technical field [0001] The invention relates to a zinc oxide nanorod functionalized cotton fiber and a preparation method thereof, belonging to the field of functional nanometer materials and textile materials. Background technique [0002] Cotton fiber is loved by consumers for its excellent properties such as moisture absorption, breathability, comfort, softness, warmth retention, renewable and degradable. However, compared with synthetic fibers, the functionality of cotton fibers is still insufficient. For example, cotton fiber has the characteristics of large specific surface area and strong moisture absorption capacity, so it is easy to attach, multiply and spread microorganisms during consumption, resulting in a decrease in the strength of cotton fibers, stains, fading and odor, and even the spread of diseases, affecting human health. Excessive UV exposure can cause skin damage, aging, and even cancer. Therefore, in order to fully tap the potential functions of cotto...
