Abstract

The invention relates to an arranging method of nanometer magnesium oxide anti-ultraviolet hydrophobic cellulose fabrics, which comprises the following steps: (1) soaking cellulose fabrics in a magnesium acetate aqueous solution for a certain time, baking at 100-150 DEG C for 10-90 minutes; (2) mixing long-chain aliphatic acid, water and alcohol to obtain a water-repellent agent; or mixing long-chain aliphatic acid salts which are water-soluble at room temperature, organic acid, water and alcohol to obtain a water-repellent agent; (3) performing water-repellent arrangement of the fabrics obtained in step (1) by using the water-repellent agent obtained in step (2), finally predrying and baking the arranged fabrics to obtain the product. The arranging method of the invention is simple, easyto be industrialized, and has low raw material cost; fabrics treated by the invention have excellent hydrophobicity and excellent anti-ultraviolet performance, and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of finishing of multifunctional fabrics, in particular to a finishing method of nano magnesium oxide anti-ultraviolet hydrophobic cellulose fabrics. Background technique [0002] In recent years, the harm of excessive ultraviolet radiation to the human body has attracted people's attention. Different cellulose fabrics have different UV transmittance, especially for summer and autumn clothing, because the cellulose yarn used has a low linear density, the fabric has a low warp and weft density, and the UV transmittance is high, so it must be improved. [0003] It is difficult for water droplets to stay stably on super-hydrophobic surfaces (the contact angle with water is greater than 150°), which can effectively curb the phenomena related to water droplets, such as pollution on the surface of materials, snow accumulation, etc., and can be widely used in medical personnel's clothing, Rain / snow clothing, tents, military ...
