Problems solved by technology

There are fewer product varieties, unsatisfactory product performance, instability, poor washability, environmental pollution, and high energy consumption for finishing and processing
Similar foreign products mainly include antistatic agent EP of CIBA, British ICI company, etc. The hydrophilic antistatic effect of these antistatic agents is better than that of domestic hydrophilic antistatic agents, but The price is expensive, and it is difficult for domestic printing and dyeing factories to accept
And there are fewer product varieties, complex chemical preparation methods, long production process, and high requirements for production equipment
In terms of effect, the finishing and processing of foreign products consumes a lot of energy, and the performance of some products is not ideal

preparation example Construction

[0043] The preparation method of hydrophilic antistatic agent of the present invention, carries out according to the following steps:

[0044] Step 1: According to mass percentage, take 8%-18% of dimethyl terephthalate, 38%-48% of ethylene glycol, 16%-26% of polyethylene glycol, 6%-16% of zinc acetate, three 4% to 14% of antimony oxide and 3% to 8% of triphenyl phosphate;

[0045] Step 2: Perform transesterification

[0046] The dimethyl phthalate, ethylene glycol and polyethylene glycol obtained in step 1 are mixed and heated to a molten state, stirred to form a molten liquid, and the zinc acetate and antimony trioxide weighed in step 1 are added to the molten liquid respectively. Halfway, when the temperature of the molten liquid is 80°C to 130°C, nitrogen gas is introduced to protect the molten liquid, and the heating is continued to raise the temperature of the molten liquid to 150°C to 195°C, and the reaction is 5h to 8h. During the reaction, acid The gaseous product-me...

Embodiment 1

[0057] According to mass percentage, dimethyl terephthalate 8%, ethylene glycol 48%, polyethylene glycol 16%, zinc acetate 11%, antimony trioxide 14% and triphenyl phosphate 3%, each group The total amount of the ingredients is 100%; dimethyl phthalate, ethylene glycol and polyethylene glycol are mixed and heated to a molten state, stirred to form a molten liquid, and 5.5% of zinc acetate and antimony trioxide are added to the molten liquid 7%, when the temperature of the molten liquid is 80°C, feed nitrogen gas to protect the molten liquid, continue heating, so that the temperature of the molten liquid rises to 150°C, and react for 5 hours. During the reaction, an acid burette is used to collect the methanol produced by the reaction Gas, the amount of methanol in the acid burette stops increasing, that is, the transesterification is completed, and the reacted product is protected by nitrogen at 80°C, and left for 3 hours to obtain the transesterified product; triphenyl phospha...

Embodiment 2

[0060] According to mass percentage, dimethyl terephthalate 13%, ethylene glycol 43%, polyethylene glycol 26%, zinc acetate 6%, antimony trioxide 4% and triphenyl phosphate 8%, each group The total amount of points is 100%; dimethyl phthalate, ethylene glycol and polyethylene glycol are mixed and heated to a molten state, stirred to form a molten liquid, and 3% zinc acetate and 2% zinc acetate are added to the molten liquid respectively. Antimony trioxide, when the temperature of the molten liquid is 105°C, nitrogen gas is introduced to protect the molten liquid, and the heating is continued to raise the temperature of the molten liquid to 172°C, and the reaction is for 6 hours. During the reaction, an acid burette is used to collect the reaction product methanol, the amount of methanol in the acid burette stopped increasing, and the transesterification was completed. The product after the reaction was protected by nitrogen at 105°C and left for 4 hours to obtain the transester...

Abstract

The invention discloses a polyester fabric hydrophilic antistatic agent which consists of the following components by weight percentage: 8 to 18 percent of DMT, 38 to 48 percent of glycol, 16 to 26 percent of polyoxyethylene, 6 to 16 percent of zinc acetate, 4 to 14 percent of diantimony trioxide and 3 to 8 percent of triphenyl phosphate, and the total amount of all the components is 100 percent.Interchange esterification and condensation polymerization are carried out to all the components so as to obtain the hydrophilic antistatic agent. The hydrophilic antistatic agent is adopted to prepare fabric-washing treatment liquid, and during the process the magnesium chloride hexahydrate is added and a two-dipping-two-rolling method is adopted to deal with the polyester fabric, and then the fabric is dried so as to complete the later finishing to the terylene fabric. The hydrophilic antistatic agent of the invention has stable antistatic capability, good washing resistance and low price. Adopting the antistatic agent to the later finishing of dacron can save the baking process of applied process so as to reduce energy cost and enhance the wearing property of polyester fiber and corresponding fabrics so as to meet the simulation requirement to polyester fabrics of costume fabric market.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber simulation, and relates to an antistatic agent, in particular to a hydrophilic antistatic agent for polyester fabrics, and also relates to a preparation method of the hydrophilic antistatic agent and the use of the hydrophilic antistatic agent to process polyester Methods of finishing fabrics. Background technique [0002] Polyester fiber has excellent properties incomparable to natural fibers such as good elasticity, high strength, wear resistance, corrosion resistance, and no moth, and the market demand continues to expand. However, its own shortcomings such as low moisture regain, poor hygroscopicity, easy to be charged with static electricity, easy to absorb dirt, difficult to wash off stains, and poor hand feel reduce the quality of polyester fabrics and affect the application of polyester fabrics. Quantity is limited. [0003] The shortcomings of polyester fabric can be improved and...
