The invention relates to the field of preparation of
textile auxiliaries. The invention relates to a method for preparing a fluorosilicone waterproof finishing agent for cotton fabrics. The invention provides a waterproof finishing agent specially for cotton fabrics. The finishing agent consists of a medium-length It is composed of chain
alkyl cationic polysiloxane
emulsion and a new type of organic fluorosilicon
emulsion. During the synthesis process, modified
silicone oil with higher
silicon-
hydrogen bond content is added to prevent the
emulsion from forming a double-layer
silicone resin film on the polar surface. The problem of decreased hydrophobicity and water-washing resistance; a new type of organic fluorosilicon
copolymer emulsion provided by the present invention is obtained by catalytic
polymerization of short
fluorocarbon chain monomers and cyclosiloxanes that are low in cost, difficult to degrade, and more
environmentally friendly. The problem of high cost and heavy
pollution of the
fluorine-containing emulsion is solved; the
surface layer of the cotton fabric finished by the finishing agent of the invention is smooth and smooth, and the
hydrophobic effect is better. Combined with softness and hydrophobicity, it is a product with great potential, profound meaning and great production value.
