Why production technology of the present invention adopts two-step method, and two reasons are arranged:
1, in process of production, the accessory substance of esterification is methyl alcohol, and the accessory substance of polymerisation is ethylene glycol, and same still system is produced while reclaiming accessory substance (methyl alcohol, ethylene glycol), can cause cross pollution, needs distilation again.And after substep, the purity of the by-product carbinol of esterification can reach more than 90%, the purity of polymeric by-products ethylene glycol can, to more than 99%, not need again distilation can work as raw material.Direct circulation is used, and has not only simplified production technology, and has adapted to energy-saving and cost-reducing environmental protection trend.
While 2, adopting one-step technology to produce, in polymerization process, along with the raising of the degree of polymerization, the material molecular weight increases, and material viscosity increases, and the motor of reactor is often shut down because of traffic overload, once can't start after shutting down, causes serious quality problems.
Such as, 3 tons of reaction kettle of the esterification, reaction mass viscosity is very low, and configuration 5KW motor can meet fully; 3 tons of polymerization reaction kettles, along with the raising of the degree of polymerization, the material molecular weight increases, and material viscosity increases, and must configure the above motor of 18.5KW and just can guarantee normal production; Under normal conditions, polymerisation power of motor used is larger, and the power of motor that esterification is used is little, and it is fast that the speed of stirring is wanted, and adopts substep just can reduce production costs and increase the quality control point.
The modifier of producing by production technology of the present invention can carry out modification to polyester fiber, make the polyester fiber after modification there is good moisture absorbing and sweat releasing property, fluffy flexibility, thereby greatly improved the comfortableness of using the fabric that the polyester fiber after modification makes.In addition, the invention also discloses and using described modifier as mother liquor, compositely go out the multiple enhancement mode modifier that polyester fiber carried out to modification such as fluffy finishing agent, level and smooth hydrophilic finishing agent and durable antistatic agent:

The third: the durable antistatic agent, contain part by weight and be the quaternary ammonium salts polymer that 5～10% above-mentioned modifier and part by weight are 20～50%, surplus is water.This durable antistatic agent can make the polyester fiber after modification not only have fluffy flexibility, also have good antistatic property simultaneously.Described quaternary ammonium salts polymer can be selected alkyl tertiary amine chloride or alkyl tertiary amine nitrate.
The 4th kind: soil release finishing agent, contain part by weight and be glycerine or ethylene glycol or fluorine resin that 5～10% above-mentioned modifier and part by weight are 2～5%, surplus is water.This soil release finishing agent can make the polyester fiber after modification not only have fluffy flexibility, also strengthen dirt-removing power simultaneously.
The 5th kind: anti wrinkling agent in bath, contain part by weight and be the polyacrylamide that 5～10% above-mentioned modifier and part by weight are 0.5～3%, surplus is water.That is: described modifier can be used with bathing with polyacrylamide in high temperature-pressure dyeing machine, make the polyester fiber after modification not only there is fluffy flexibility and good wrinkle resistance, improved again the in use stiff problem of feel of polyacrylamide simultaneously.
The 6th kind: hydrophilic wrinkle resistant high temperature levelling agent contains part by weight and is 3～10% above-mentioned modifier in hydrophilic wrinkle resistant high temperature levelling agent used.This hydrophilic wrinkle resistant high temperature levelling agent can make the polyester fiber after modification not only have fluffy flexibility, can also improve dyeing quality, makes dyeing fabric color afterwards more even, bright-coloured simultaneously.
The 7th kind: the application of described modifier in the dacron fabric dyeing, be characterized in: in dyeing, together with other auxiliary agent of modifier and dye well, adding, the addition of modifier is 0.05～5% of fabric weight, and dyeing temperature is used in the time of 60～130 ℃.
