A kind of preparation method of the anti-electrostatic polyester tablecloth
Technical field:
The invention belongs to textile material technical field, be specifically related to a kind of preparation method of the anti-electrostatic polyester tablecloth.
Background technology:
Electrostatic phenomenon is common in all kinds of textiles. Eliminate electrostatic phenomenon, obtain anti-static function is textile material research field alwaysOne of focus (YouyiXia, YunLu. " Fabricationandpropertiesofconductiveconjugatedpolymers/silkfibroincompositefibers”,《CompostieScienceandTechnology》,2008,68,1471-1479)。
The tablecloth is that a class is covered on platform, desktop in order to antifouling or increase textile attractive in appearance. As the high-grade tablecloth of one, washThe synthetic fibre class tablecloth is widely used in furnishings, dinner party, dining etc. But, because the polyester fiber hydrophily of the formation terylene class tablecloth is poor,Cause its electrostatic phenomenon very serious, thereby in processing and use procedure, often cause serious fluffing, pilling effect, special(Liu Yuqiang etc., " nano zine oxide-iron oxide mixed sols is anti-to dacron under environment, also can to produce blast, disaster hidden-troubleElectrostatic efficiency ", " textile journal ", 2013,34,17-23). Therefore, the anti-static function of the endowing terylene class tablecloth be one urgentlyProblem to be solved.
Carrying out modification in textile surface, is the common methods that solves electrostatic phenomenon. Than all kinds of antistatic additive, conjugative monomerIn the polymerization of fiber surface, convenient, nontoxic because of it, therefore develop into the new methods of preparing antistatic textile. As inState patent CN103468541A discloses a kind of simple preparation process of antistatic surface dacron, and the method is in dacron tableFace carries out aniline polymerization, has obtained anti-static fabric; Chinese patent CN102943388A discloses a kind of home position polymerization reaction preparationThe method of Antistatic polyester fabric, the method adopts home position polymerization reaction also to obtain a class anti-static fabric. Application said methodThough can obtain the terylene class tablecloth of certain antistatic behaviour, but, also there is the problems such as resistance is bigger than normal, antistatic behaviour is not good enough.
Summary of the invention:
The present invention is directed in the existing anti-electrostatic polyester tablecloth and have technical problem, a kind of preparation side of the anti-electrostatic polyester tablecloth is providedMethod.
