Abstract

The invention discloses a cationic binder emulsion for pigment dyeing as well as a preparation method and application thereof. The binder emulsion is generated by carrying out reaction on the following components: a soft monomer, a hard monomer, a cross-linking monomer, a cationic monomer, a comonomer, a composite emulsifier of a cationic surfactant and a nonionic emulsifier and an initiator. Thepreparation method comprises the following steps of adding a mixture of the soft monomer, the hard monomer and the cross-linking monomer and an initiator aqueous solution into the emulsifier and distilled water for reaction, carrying out rapid heating, rapidly adding the comonomer, carrying out rapid cooling, adjusting the pH value, carrying out cooling, carrying out heat preservation reaction, and carrying out filtering so as to obtain the cationic binder emulsion. According to the cationic binder emulsion as well as the preparation method and application thereof, water-based latex not only is simple and convenient in preparation method, but also can be used for pigment dyeing for textiles.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a cationic binder emulsion for paint dyeing, a preparation method and application thereof. Background technique [0002] The key to paint dyeing is to improve the feel of paint-dyed fabrics, rubbing fastness, adhesion to rolls during pad dyeing, and the depth of color and level dyeing of exhaust dyeing. The solution to these problems depends on the development of paint color paste, adhesives and other technologies. [0003] Adhesives are synthetic polymer compounds, which are polymerized from monomers and are generally made into water dispersions, emulsions and solvents. Adhesives for paint dyeing are required to have cross-linkable or self-cross-linkable groups, and after being dyed with pigments to form a colorless, transparent, strong adhesive, elastic and tough film. [0004] The quality of paint dyeing depends largely on the nature of the binder. Adhe...
