Abstract

This invention relates to an emulsion-type fabric finishing agent containing fluorine and its method for making. It is a high molecular polymer emulsion of acrylic esters containing full-fluorine alkyl on the lateral chain. The finishing agent includes: fluorine monomer(10.00-30.00%), non-fluorine monomer (1.00-15.00%), functional monomer(0.10-5.00%), monomer of enhancing adhesive force(0.10-5.00%), initiating agent(0deionized water.10-2.00%), emulsifier(1.00-3.50%), chain-transferring agent(0.01-0.20%) and deionized water(60.00-80.00%), beforehand emulsifying them and polymerizing the emulsion to get it. It can be used in water and oil repellent finish of polyurethane, polyester, chandar, chandar / polyester, chandar / natural hemp, spun rayon fabric. Compared with the present technique, the finishing agent produced with the invention comprises the following merits: big adhesive force, no volatile solvent, good water and oil repellency, fine durability.

Description

technical field [0001] The invention relates to a preparation technology of an emulsion type fluorine-containing finishing agent, in particular to the oil-repellent and water-repellent finishing of polyurethane, polyester, cotton, cotton / polyester, cotton / natural hemp, and artificial cotton fabrics. Background technique [0002] Fluorine-containing fabric finishing agent is an important finishing agent for textile finishing. Fabrics treated with fluorine-containing fabric finishing agent can show characteristics that ordinary hydrocarbon or silicone resin finishing agents cannot achieve, that is, oil repellency and water repellency. , Pollution repellency. When water droplets or oil are spilled on the fabric, they cannot penetrate into the fabric immediately, but roll freely on the surface in the form of beads, forming good water and oil repellency. Polyurethane, polyester, cotton, cotton / polyester, cotton / natural linen, rayon fabric fibers, etc., after finishing with fluor...
