  The invention relates to a high uniformity coloured polyester industrial yarn and its preparation method. The raw material of the high-uniformity coloured polyester industrial yarn is the modified polyester composed of terephthalic acid segment, an ethylene glycol segment and a branched diol. The high-uniformity coloured polyester industrial yarn is prepared by the esterification reaction of terephthalic acid with a branched diol using concentrated sulfuric acid as catalyst to obtain a terephthalic acid glycol ester. Terephthalic acid and ethylene glycol are formulated to carry out esterification reaction to obtain ethylene terephthalate. Finally, stir and mix the two materials and carry out the polycondensation reaction in the low vacuum stage and the high vacuum stage under the action of the catalyst and the stabilizer to obtain modified polyester. Measure the modified polyester and add black masterbatch. After porous spinneret extrusion, cooling, oiling, drawing, heat setting and winding the modified polyester, we can obtain high uniformity coloured polyester industry yarn.

  A method for preparing the modified polyester. The modified polyester segments include terephthalic acid segment, ethylene glycol diol segment and branched diol segment, in which the branched diol segment refers to a diol segment in which a branch is located on a non-terminal carbon in the glycol segment and the branch is a linear carbon chain having 5 to 10 carbon atoms. The method includes preparing terephthalic acid glycol ester through the esterification of terephthalic acid and branched diol using the concentrated sulfuric acid as the catalyst. Then get ethylene terephthalate through the esterification of terephthalic acid and ethylene glycol. After stirring and mixing the two, the modified polyester can be obtained through polycondensation reaction of a low vacuum stage and a high vacuum stage using the catalyst and stabilizer.
