Abstract

The invention discloses an antibacterial hydrophobic finishing method for linen rayon interwoven fabric. The method comprises the following steps: S1, pretreating the linen rayon interwoven fabric, then performing dip padding in an aqueous solution containing polycarboxylic acid and sodium hypophosphite, and predrying the material to obtain the linen rayon interwoven fabric with a surface containing a -COOH group; and S2, performing dip padding on the linen rayon interwoven fabric with the surface containing the -COOH group obtained in the step S1) in an aqueous solution containing an organicantibacterial hectorite, cyclodextrin modified glycidyl 3-(trimethoxysilyl)propyl ether, nano zinc oxide and nano silica sol, and then performing drying treatment to obtain the antibacterial hydrophobic linen rayon interwoven fabric. According to the antibacterial hydrophobic finishing method of the linen rayon interwoven fabric proposed by the invention, the linen rayon interwoven fabric has theexcellent antibacterial and hydrophobic properties.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to an antibacterial and hydrophobic finishing method for linen and rayon interwoven fabrics. Background technique [0002] In the past, compounds containing long fluorocarbon chains were mostly used as hydrophobic finishing agents to obtain fabrics with low surface free energy. Although compounds containing fluorine systems have better finishing effects, such finishing agents are expensive. It is found that fluorine-containing chemicals are difficult to biodegrade and cause potential harm to the environment and human health. Therefore, how to make environmentally friendly finishing agents achieve the finishing effect of compounds with long fluorocarbon chains is an important issue in the development of functional fabrics today. At present, there are also reports in the literature that inorganic nanoparticles such as silica and titanium dioxide are used to construct rough ...
