Embodiment 1

[0009] A kind of preparation method of organic silicon fabric smoothing agent, A) take the simethicone oil that viscosity is 500CPS as raw material, add the hydroxyl silicone oil that viscosity is 2 million CPS and the hydroxyl silicone oil of SCA-602 modification, disperse with high-speed disperser Less than 2 hours, a mixed silicone oil is formed, wherein the addition of hydroxy silicone oil is 25% of the weight of simethicone, and the addition of SCA-602 modified hydroxy silicone oil is 3% of the weight of simethicone; B) using high speed Dispersion and phase inversion method, the composite surface emulsifier isomeric fatty alcohol polyoxyethylene ether is added to the mixed silicone oil, and deionized water is added dropwise while stirring at room temperature to form a composite silicone emulsion of oil-in-water O / W. The addition of fatty alcohol polyoxyethylene ether is 25% of the weight of the mixed silicone oil, and the addition of deionized water is 3 times of the weigh...

Embodiment 2

[0011] A kind of preparation method of silicone fabric smoothing agent, A) take the simethicone oil that viscosity is 3000CPS as raw material, add the hydroxyl silicone oil that viscosity is 500,000 CPS and the hydroxyl silicone oil modified by SCA-602, disperse with high-speed disperser Less than 2 hours, a mixed silicone oil is formed, wherein the addition of hydroxy silicone oil is 10% of the weight of simethicone, and the addition of SCA-602 modified hydroxy silicone oil is 5% of the weight of simethicone; B) using high speed Dispersion and phase inversion method, the composite surface emulsifier isomeric fatty alcohol polyoxyethylene ether is added to the mixed silicone oil, and deionized water is added dropwise while stirring at room temperature to form a composite silicone emulsion of oil-in-water O / W. The addition of fatty alcohol polyoxyethylene ether is 35% of the weight of the mixed silicone oil, and the addition of deionized water is 5 times of the weight of the mix...

Abstract

The present invention relates to a preparation method of organosilicon fabric smooth agent. Sad preparation method includes the following steps: using hydroxyl-capped dimethyl silicone oil with ultrahigh viscosity and making it be mixed with low-viscosity dimethyl silicone oil so as to reduce viscosity, then making said mixture be mixed with emulsifying agent to make emulsification, then using high-speed shear emulsifying machine to make emulsification and prepare organosilicone smooth agent emulsion, then adding smooth synergistic agent nano oxypolyethylene wax emulsion and preparing organosilicone fabric smooth agent.

Description

Technical field: [0001] The present invention relates to a treatment of fibers, yarns, fabrics or fibrous products made from these materials with macromolecular organic compounds which, at least during the subsequent mechanical treatment, can be present in the interior or on the surface of the fabric , particularly relates to a preparation method of a silicone fabric smoothing agent. Background technique: [0002] In order to increase the added value of the fabric, in the post-treatment process of the fabric, the fabric is often treated with a silicone fabric smoothing agent, so that the treated fabric is smooth, soft, fluffy and elastic, and has a cashmere-like feel. "Printing and Dyeing Auxiliaries" published the article "GH Series Mercerized Wool Smoothing Agent" in the third issue of 2004, using self-made high-viscosity hydroxyl-terminated polydimethylsiloxane (107 glue) and smoothing accelerator -Silicone oil is emulsified into emulsion by its weight ratio of 5: 1, an...
