MANUFACTURING METHOD OF UV-LIGHT BLOCKING FABRIC TREATMENT AGENT AND FABRIC TREATMENT AGENT MADE BY THE SAME

摘要

The present invention relates to a fabric treatment agent manufacturing method by which elasticity and a UV-blocking function of a fabric can be improved, a fabric treatment agent manufactured by using the same, and a fibrous base material treated with this fabric treatment agent and, more particularly, to a UV-blocking fabric treatment agent manufacturing method in which a UV absorber containing a benzophenone-type vinyl monomer and butyl acrylate is added to a polyurethane-based emulsion composition manufactured by a manufacturing method including a first step in which a polyol mixture containing 20 to 40 mol% of polytetramethylene glycol (PTMG), 5 to 20 mol% of polydimethylsiloxane (PDMS), and 40 to 60 mol% of N-nitrosodiethanolamine (NDEA) is heated to 70 to 120 degrees Celsius, a second step in which the polyol mixture of the first step and isophorone diisocyanate (IPDI) are mixed at a molar ratio of 1 : 1 to 1.2, a catalyst is added, and curing is performed with the temperature lowered to 40 degrees Celsius, a third step in which neutralizing agent addition and neutralization are performed at 40 degrees Celsius, and a fourth step in which aqueous dispersion is performed, a fabric treatment agent manufactured by using the same, and a fibrous base material treated with this fabric treatment agent.
