Abstract

The invention relates to a preparation method of fabric with flame-retardant and hydrophobic functions. The preparation method comprises the following steps: performing padding finishing of fabric by use of an aqueous solution containing polybasic carboxylic acid and a catalyst, and drying to obtain pretreated fabric; uniformly mixing siloxane, a cationic surfactant and a nonionic surfactant in water; adding a flame retardant, and adjusting the pH to 2-3 for reacting to obtain sol doped with the flame retardant; adding silicate ester into the sol for reacting; after the reaction, adding long-chain alkyl silane as a hydrophobic agent for further reacting to obtain flame-retardant hydrophobic finishing liquid; impregnating the pretreated fabric in the flame-retardant hydrophobic finishing liquid;, and performing rolling baking, washing and drying to obtain the fabric with flame-retardant and hydrophobic functions. The fabric finished by the method has relatively good flame retardance and hydrophobicity as well as resistance to repeated washing; and moreover, without using an organic solvent in the preparation process, the method is conducive to environmental protection.

Description

technical field [0001] The invention relates to the technical field of functional textile finishing, in particular to a method for preparing fabrics with flame-retardant and hydrophobic functions. Background technique [0002] As protein fibers, wool and silk are favored by consumers due to their warmth retention and soft texture, and are widely used in high-end textile fabrics, such as bedding, woolen coats, curtains, wall coverings, aircraft, car interiors, outdoor sportswear, etc. aspect. However, once these items are burned, they may cause huge property and personnel safety problems. Therefore, in order to increase the added value of such high-end textile products, there have been many studies on flame retardancy of such fabrics since the 1970s, but the results are not satisfactory: not washable, harmful to the environment and human body . In recent years, the development of high-efficiency, low-toxic and non-toxic new flame retardants has become a research hotspot at...
