For achieving the above object, technical scheme of the present invention is the regenerate preparation method of painted polyester staple fiber of a kind of CATION of design, comprises the steps:
1) by ethanol and carboxylic acid hybrid reaction, obtain carboxylate, the temperature of reaction is 235~240 ℃;
2) PET sheet material, 5 parts by mass three monomer dimethyl isophthalate~5~sodium sulfonates, 15~20 parts by mass Masterbatch mixing copolyreaction of 150 parts by mass carboxylates and the regeneration of 1200 parts by mass are formed to copolymer; The temperature conditions of described copolyreaction is 290 ℃, and vacuum is 60Pa;
3) copolymer of 260 ℃ is crossed to 300 mesh filter screens, remove impurity;
4) crystallization: will go deimpurity copolymer through the crystallization of crystallization case, and form the high molecular polymer partly solidifying; The temperature of crystallization case is that 290 ℃, pressure are 25MPa;
5) spinning: the high molecular polymer partly solidifying is passed through to the spinnerets of 270 ℃, at pressure, be that 45MPa extruder, spinning speed are that 1500 ms/min, hauling speed are to extrude under 1300 ms/min of conditions, by coiling, add spinning oil again, make Regenerated Polyester Staple Fiber dimension.
Advantage of the present invention and beneficial effect are: the preparation method who provides a kind of CATION to regenerate painted polyester staple fiber, it makes full use of waste and old terylene staple fibre, without can obtain painted CATION bright-coloured, that glossiness the is good painted polyester staple fiber of regenerating by follow-up printing and dyeing.
