Problems solved by technology

[0003] However, with the continuous improvement of people's living standards, single-function textile finishing agents can no longer meet people's needs, and the fabrics finished with amino silicone oil have the defects of poor waterproof effect and easy yellowing.
At the same time, when reactive dyes are used to dye cotton fabrics, there are problems such as large amount of dyeing materials, not deep dyeing, floating color on the surface and poor washing fastness.

Abstract

The invention discloses a preparation method of a fabric waterproof deepening finishing agent and a product prepared by the preparation method. The preparation method comprises the following steps ofpreparing p-acryloyloxybenzoic acid; preparing tridecafluorooctyl p-hydroxybenzoate; preparing 2-(perfluorohexyl)ethyl-4-[4-(acryloyloxy)-benzoyloxy]benzoate; preparing fluorine-containing alkyl modified amino silicon oil; and preparing the fluorine-containing alkyl modified amino silicone oil emulsion. In the molecular structure of the fabric waterproof deepening finishing agent, 2-(perfluorohexyl)ethyl-4-[4-(acryloyloxy)-benzoyloxy]benzoate is used as a fluorine-containing functional monomer, two rigid benzene rings are connected through an ester group, and an environment-friendly short fluorocarbon chain is bonded to an amino silicon oil molecule by using the 2-(perfluorohexyl)ethyl-4-[4-(acryloyloxy)-benzoyloxy]benzoate as a linking group. The liquid crystal effect of the biphenyl group is utilized to promote the short fluorocarbon chain to be outwards perpendicular to the surface of a matrix for regular arrangement, and a more remarkable and effective fluoroalkyl shielding effectis provided, so that an excellent waterproof deepening effect is brought.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis and textile chemical auxiliary agents, and in particular relates to a preparation method and a product of a fabric waterproof and darkening finishing agent. Background technique [0002] Amino silicone oil can be regarded as the product after part of the side or terminal methyl groups in dimethyl silicone oil are replaced by aminohydrocarbon groups, because the polarity of the amino group in the molecular structure is strong, and it can interact with the hydroxyl group, carboxyl group and other groups in the fiber. Function, produce strong orientation and adsorption, make siloxane oriented arrangement on the fiber, so as to endow the fabric with soft, smooth and elastic finishing effect, known as the new generation of best silicone oil softener. [0003] However, with the continuous improvement of people's living standards, single-function textile finishing agents can no longer meet peopl...
