Technical solution of the present invention also comprises the static inhibitor that is used for polyester piece good that obtains by above-mentioned preparation method, and described static inhibitor is to the application in the antistatic finish of polyester piece good.
Principle of the present invention is: adopt vinylformic acid that the part terminal hydroxy group of hyper-branched polyester is carried out modification, another part terminal hydroxy group and the reaction of chlorination Racemic glycidol trimethyl ammonium, control chlorination Racemic glycidol trimethyl ammonium and acrylic acid amount of substance ratio.Acrylic acid consumption can not too much can not be very few, and consumption is too much, and the quantity of two keys is just many in institute's synthetic modified ultra-branching polyester, and water soluble group quantity is few, causes its decreased solubility, hinders the carrying out of polyreaction; Consumption is very few, and the quantity of two key groups is few, and the side chain that can participate in polyreaction also just reduces, and causes molecular weight of product low, and film-forming properties is relatively poor.Hyper-branched polyester after the modification carries out solution polymerization with acrylamide, dimethyl diallyl ammonium chloride and glycidyl allyl ether again, prepares a kind of novel cationic static inhibitor.
Test antistatic property provided by the invention by FZ/T 01042-1996 " textile materials antistatic property, static voltage half life determination " method, press its washing fastness of GB/T3921.1-1997 standard testing, the induction static voltage of the polyester piece good after the arrangement of this static inhibitor is 0.00~0.03kV, transformation period is 0.00s, the induction static voltage of washing polyester piece good after 15 times is 0.45~0.69kV, and the transformation period is 1.23~1.60s.
Because the utilization of technique scheme, the present invention compares with prior art, has following advantage:
1, hyper-branched polyester of the present invention has and the similar highly branched structure of dendrimer, and the structure end has a large amount of terminal hydroxy group, and the chemical modification of terminal hydroxy group is easier to;
2, one aspect of the present invention adopts the cationic monomer diallyldimethylammonChloride Chloride and the hyper-branched polyester after the modification that have than strongly hydrophilic to carry out polymerization, a large amount of reactive functional groups that the modified ultra-branching polyester is provided can improve the quantity of cation group in the polymkeric substance by a relatively large margin; On the other hand, employing bridging property glycidyl allyl ether preferably is a cross-linking monomer, make cation superpolymer in the crosslinked film forming of fiber surface with reactive functional groups, can improve the wash durability of static inhibitor effectively, the amide group that acrylamide provided simultaneously can remedy the crosslinked problem of bringing feel to descend as soft chain segment, so the arrangement back is less to the feel influence of fabric;
3, technology of the present invention is simpler, and reaction process is convenient to control, is fit to suitability for industrialized production.
