Abstract

The invention belongs to the technical field of textile assistants, and particularly relates to a silicone oil emulsion with stable soft nanoparticles. The product comprises the following components in parts by mass: 20-30 parts of amino silicon oil, 2-8 parts of an emulsifier, 3-32 parts of a soft nanoparticle emulsion, 0.8-1.5 parts of a pH regulator and 50-60 parts of deionized water. The invention further provides a specific preparation method. The problems that a traditional silicone oil emulsion is poor in stability and the textile finishing effect is poor are solved, the emulsion stability is excellent, the adhesiveness on fibers is good, the air permeability and softness of textiles can be effectively improved, and therefore the practicability and comfort of the textiles are improved; meanwhile, the product has the characteristics of low cost and simple process.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a silicone oil emulsion stabilized by soft nanoparticles and a preparation method thereof. Background technique [0002] Silicone oil has the characteristics of soft chain segment and low surface tension, which can significantly improve the softness of fabrics, and is widely used in fabric softening and simulation finishing. At present, the fabric finishing agent commonly used in the market is mainly amino silicone oil emulsion, but its storage stability is poor, it is generally easy to break emulsion, easy to yellow, and the finished fabric is hydrophobic and does not absorb sweat, which greatly affects the fabric's durability Comfort and looks. Traditional silicone oil emulsions are mainly stabilized by electrostatic stabilization, reduction of interfacial tension, and steric stabilization by means of surfactants or soluble macromolecules. Due to the d...
