Problems solved by technology

However, when acrylate emulsion is used to print dark fabrics (generally, the amount of liquid disperse dye is more than 2%), there are problems that the fastness is not up to standard when the amount is small, and the hand feeling is not good when the amount is large.

Abstract

The invention discloses a preparation method of fluorosilicon modified acrylate emulsion and its application in liquid disperse dye printing. The preparation method comprises: (1) synthesis of fluorosiloxane (2) taking isooctyl acrylate, methyl methacrylate, acrylic acid, n-hexadecane and the fluorosiloxane obtained in step (1) and stirring evenly, then adding into the emulsifier aqueous solution to obtain a pre-emulsion; take the pre-emulsion and add it to a reactor as a seed emulsion, add an ammonium persulfate aqueous solution to the seed emulsion for reaction, and cool to obtain a fluorosilicon-modified acrylate emulsion. The method of the present invention introduces fluorine silicon chain segment on the basis of acrylate. The softness of the organic silicon segment can effectively improve the hand feeling of printed fabrics; the short C-F covalent bond and its large bond energy of organic fluorine can improve the hydrophobicity of the film, reduce the solubility parameter and refractive index of the film, and help It is used to improve the color fastness and color yield of fabrics.

Description

A kind of preparation method and application of fluorosilicon modified acrylate emulsion technical field The present invention relates to fluorosilicon modified acrylate emulsion field, be specifically related to a kind of fluorosilicon modified acrylate emulsion Preparation method and application in liquid disperse dye printing. Background technique During disperse dye printing, color paste dyes are mostly powder disperse dyes, which are mainly colored by hot-melting, and then Wash with water to remove various residual auxiliaries and dyes. This process is a serious waste of water resources and sewage damage to the environment. Currently, Liquid disperse dyes appear on the market, and light-colored fabrics are realized after color development by thermal fusion (generally, the amount of dyes is less than 0.5%) The color fastness of medium and dark fabrics is not up to standard after no-wash printing. Therefore, water is still required for medium and dark fabrics af...
