1. a durability crease-shedding finishing agent, is characterized in that:

  • comprise following key component;

    with parts by weight,Dihydroxymethyl carbamide resin 15-20Dihydroxymethyl triazinone 18-30Melamine methylol 12-15Butyl acrylate 2-5Ammonium citrate 7-10Maleic acid-acrylic acid copolymer 3-6Polycarboxylate 1-1.5Fatty alcohol-polyoxyethylene ether 2-5Nano titanium oxide 0.5-3Dispersant 1-2Bleeding agent 3-6;

    The preparation process of described dihydroxymethyl carbamide resin is as follows;

    in ceramic reactor, add the formalin that mass percent is 37-40%, regulate the pH value of formalin to be 7.5-9.0 by the NaOH solution of mass percent 10%, stir 30-40min and pH value is tended towards stability;

    Under agitation evenly and lentamente adding with formaldehyde mole ratio is afterwards the urea of 1;

    1.6-1.8, starts to be heated to connect backflow when temperature is about 50-60 DEG C, and control temperature is 80-100 DEG C, insulation, and the reaction time is about 30-60min;

    After condensation reaction completes, add frozen water keeps temperature of charge below 4 DEG C, is stirred to resin initial reduced body and is fully dissolved in the water, then leave standstill a few hours, take out supernatant liquor.
