Abstract

The invention discloses an antistatic finishing agent for a polyester fabric and a preparation method thereof, the preparation method comprises the following steps: taking a prepared pre-emulsion I, heating up to 80 to 90 DEG C, performing microwave irradiation for 30 to 45 minutes, simultaneously adding 1 / 2 of an aqueous solution of an initiator into the pre-emulsion I, performing reflux thermalinsulation reaction for 2 to 3 hours after the completion of the dropwise addition of the 1 / 2 of the aqueous solution of the initiator, dropwise adding a pre-emulsion II and the remaining aqueous solution of the initiator, performing reflux thermal insulation reaction for 2 to 3 hours after the completion of the dropwise addition of the pre-emulsion II and the remaining aqueous solution of the initiator, cooling to room temperature, and adding water to dilute to obtain the antistatic finishing agent for the polyester fabric. The polyester fabric after being finished by the antistatic finishingagent has good antistatic property, is easy to process, reduces static electricity generation during use, has good water washing and abrasion resistance, and has a long service life.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to an antistatic finishing agent for polyester fabrics and a preparation method thereof. Background technique [0002] Polyester fabric has good wear resistance, stiffness, strength and chemical resistance, and is widely used in decoration, industry and clothing. Compared with natural fibers, polyester fibers have higher strength, better cloth surface texture, low price, bright color, easy processing, and are deeply loved by consumers. The basic structural unit of polyester fiber is polyethylene terephthalate, which is polycondensed from polyester monomers with symmetrical structures and has a symmetrical chemical structure. From the perspective of the composition of polyester molecules, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal hydroxyl groups. There are no other polar groups in polyester molecules except for two terminal alc...
