Problems solved by technology

The moisture and heat transfer performance of fabrics is very important. Cotton fibers have good hygroscopicity. After moisture absorption and swelling, the fiber cross section increases, resulting in tighter fabrics and lower air permeability.
When the human body sweats a lot, after the cotton fiber absorbs a lot of sweat, its drying speed is slow, and it takes a long time from the wet state to the water balance, which makes the human skin feel damp. After the cotton fiber absorbs moisture, it is easy to fit the skin and difficult to fast. dry, stuffy

Abstract

The invention provides a method for preparing an antibacterial quick-drying cotton fiber. The method comprises the following steps: (1) crushing corn straws, mixing with deionized water, performing microwave extraction, filtering and concentrating an extracting solution, diluting with ethanol, adjusting pH, after separating out a flocculent precipitate, standing for 2 hours, performing suction filtration, drying, and crushing to obtain vegetable gum, and then mixing with deionized water to form a vegetable gum solution for standby use; (2) dissolving the cotton fiber in a sodium carbonate solution, soaking at a temperature of 35 DEG C for 15 to 35 minutes, taking out and washing with deionized water; (3) dissolving antibacterial microcapsules and a penetrant NR in the vegetable gum solution, stirring evenly, and then adding glacial acetic acid to mix evenly; (4) impregnating the cotton fiber treated in step (2) in a mixed solution in step (3) to be subjected to soaking treatment, taking out and washing with ethanol and drying, and then baking to obtain the antibacterial quick-drying cotton fiber. The method for preparing the antibacterial quick-drying cotton fiber provided by the invention can make the cotton fiber have good hygroscopicity, quick-drying property and long-lasting antibacterial property.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing antibacterial and quick-drying cotton fibers. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the functionality and comfort of clothing. The comfort of clothing involves many aspects such as the structure of clothing, the heat and moisture transfer performance of materials, and the touch feel. The moisture and heat transfer performance of fabrics is very important. Cotton fibers have good hygroscopicity, and the cross-section of fibers increases after moisture absorption and swelling, resulting in tighter fabrics and lower air permeability. When the human body sweats a lot, after the cotton fiber absorbs a lot of sweat, its drying speed is slow, and it takes a long time from the wet state to the water balance, which makes the human skin feel damp. After the cotton fiber absor...
