Abstract

The invention discloses a preparation method of a textile smoothing agent, and belongs to the field of textile additives. Polydimethylsiloxane is added for sursurface graft modification of nano silica, the sursurface-graft-modified nano silica is added into emulsion, since the sursurface of the nano silica is coated with the polydimethylsiloxane in the form of a silicon-oxygen bond, organic components on the sursurface of particles are increased, the content of hydroxyl groups on the sursurface is reduced, electronegativity is reduced, hydrophobic properties are improved, defoaming and antifoaming properties are better, and the problems of emulsification difficulty and easy delamination of organosilicone can be better solved. The preparation method solves the problem that smoothing agentson the market in the prior art mostly belong to organosilicone softening smoothing agents, have a general application effect, and have the problems of easy delamination and poor emulsion stability.

Description

technical field [0001] The invention belongs to the field of textile additives, and in particular relates to a preparation method of a textile smoothing agent. Background technique [0002] Smoothing agent is a textile additive used in the textile industry. In the textile printing and dyeing industry, smoothing agent can give plush fabrics, leather fabrics, and cotton fabrics a smooth feel, and can make textiles soft, smooth and bright. It is suitable for the finished products of various fibers. It has excellent gloss, resistance to dry and wet rubbing, flexibility, strong adhesion, waterproof and anti-fouling, fast drying, high and low temperature resistance, and smooth and delicate hand feeling. Some smoothing agents are solid With high content and good dispersibility, it can be diluted with water in any proportion, thus effectively prolonging the shelf life. The smoothing agent can improve the gloss of the fabric and endow the fabric with good smoothness and gloss, so it...
