| titleOfInvention | Preparation method of polyester sun-shading cloth |
| abstract | The invention relates to a preparation method of terylene sun cloth, which is characterized in that modified polyester industrial yarns are warped, woven, rolled and attached with a PVC film to prepare the terylene sun cloth, the modified polyester industrial yarns are prepared by performing solid phase polycondensation tackifying, melting, metering, extruding, cooling, oiling, stretching, heat setting, relaxation heat treatment and winding on modified polyester melt, and the preparation method of the modified polyester before solid phase polycondensation tackifying comprises the following steps: mixing terephthalic acid, ethylene glycol, 2,3,4,5, 5-hexamethyl-3, 4-hexanediol and doped modified Sb 2 O 3 And uniformly mixing the powder, and then carrying out esterification reaction and polycondensation reaction, wherein the relaxation heat treatment means that the modified polyester industrial yarn passes through a space of 200-240 ℃ when the overfeed rate of winding is 3.0-5.0%. The preparation method is simple, the cost is low, and the prepared terylene sun-shading cloth has high quality, good tensile strength, high peel strength, low thermal shrinkage and wide application range. |
