Problems solved by technology

At the same time, the coagulation of the resin makes the fiber ends adhere to the yarn, and it is not easy to pill when rubbing, thus improving the pilling resistance of the knitted fabric. However, the disadvantage of these methods is that the pilling resistance of the fabric lasts longer. The durability is poor, and it is easy to make the fabric lose its original style, and the handle becomes stiff

Abstract

The invention relates to a preparation method of a quaternized organosilicon modified acrylate emulsion. The method mainly comprises the processes of: (1) synthesizing amino silicone oil by putting otcamethylcyclotetrasiloxane, a double bond-containing silane coupling agent, N-beta-(aminoethyl)-gamma-aminopropylmethyldimethoxysilane, hexamethyldisiloxane, potassium hydroxide and deionized water in a reaction container for reaction at a temperature of 100-110DEG C; (2) adding an alkyl halide or epoxy alkyl halide for quaternization treatment at a temperature of 50-90DEG C, thus obtaining quaternized modified amino silicone oil; (3) adding an emulsifier, acrylate monomers and deionized water into the quaternized modified amino silicone oil obtained on step (2), and employing an oxidation-reduction initiating system for copolymerization reaction, thus obtaining a quaternized organosilicon modified acrylate emulsion. The product of the invention can be used for textile finishing, especially for acrylic fabric, and has good pilling resistance.

Description

Technical field [0001] The present invention involves a preparation method for an acrylic emulsion, especially the preparation method of a daily ammonium -based silicon -to -silicon acrylate emulsion. Background technique [0002] In the process of wearing and washing, the spinning and washing process continued to use external forces such as friction, rubbing, and washing. The fiber end of the fabric will expose the surface of the fabric and gradually slide out from the yarn, and the phenomenon of "hair" appears.The wool fabric is constantly rubbing and rubbing through the external force. The head end of the 3 to 5 fibers will be twisted together, forming a small ball, covering the surface of the fabric, and the phenomenon of "kicking".These hair balls that are protruding on the surface of the fabric are easily attached to dirt and dust, which seriously affects the wearing performance and appearance of the fabric. [0003] The raising of the fabric is closely related to the indic...
