Embodiment 1

[0018] The polyethylene glycol and polypropylene glycol were subjected to dehydration reaction respectively, and the temperature was controlled at 100-105° C. for vacuum dehydration for 1 hour. After the dehydration is completed, weigh 150g of polyethylene glycol, 42g of ethylene glycol, 0.06g of antimony trioxide and 0.15g of calcium acetate in a reaction vessel equipped with a thermometer and a nitrogen tube, stir for 10min, and add 56g of terephthalic acid di For methyl ester, the temperature was raised slowly under the protection of nitrogen. When the temperature rose to 160°C, the temperature was controlled at 160-170°C for 1 hour.

[0019] After the transesterification is completed, continue to heat up to 180°C, control the temperature at 180-190°C for 30 minutes, then raise the temperature to 200°C, control the temperature at 200-210°C for 30 minutes, continue to heat up to 220°C, add 45g of polypropylene glycol and 135g of polyethylene Diol, heat up to 260°C, control t...

Embodiment 2

[0022] The polyethylene glycol and polypropylene glycol were subjected to dehydration reaction respectively, and the temperature was controlled at 100-105° C. for vacuum dehydration for 1 hour. After the dehydration is completed, weigh 145g of polyethylene glycol, 50g of ethylene glycol, 0.08g of antimony trioxide and 0.17g of magnesium acetate in a reaction vessel equipped with a thermometer and a nitrogen tube, stir for 10min, and add 61g of terephthalic acid di For methyl ester, the temperature was raised slowly under the protection of nitrogen. When the temperature rose to 160°C, the temperature was controlled at 160-170°C for 1 hour.

[0023] After the transesterification is completed, continue to heat up to 180°C, control the temperature at 180-190°C for 30 minutes, then raise the temperature to 200°C, control the temperature at 200-210°C for 30 minutes, continue to heat up to 220°C, add 49g of polypropylene glycol and 136g of polyethylene Diol, heat up to 260°C, control...

Embodiment 3

[0026] The polyethylene glycol and polypropylene glycol were subjected to dehydration reaction respectively, and the temperature was controlled at 100-105° C. for vacuum dehydration for 1 hour. After the dehydration is completed, weigh 158g of polyethylene glycol, 45g of ethylene glycol, 0.06g of antimony trioxide and 0.2g of zinc acetate in a reaction vessel equipped with a thermometer and a nitrogen tube, stir for 10min, and add 65g of terephthalic acid di For methyl ester, the temperature was raised slowly under the protection of nitrogen. When the temperature rose to 160°C, the temperature was controlled at 160-170°C for 1 hour.

[0027] After transesterification, continue to heat up to 180°C, control the temperature at 180-190°C for 30 minutes, then raise the temperature to 200°C, control the temperature at 200-210°C for 30 minutes, continue to heat up to 220°C, add 43g of polypropylene glycol and 125g of polyethylene Diol, heat up to 260°C, control the temperature at 260...

Abstract

The invention relates to a preparation method of a super-strong washable polyester fabric moisture absorption and sweat releasing finishing agent. Dimethyl terephthalate, ethylene glycol, one part of polyethylene glycol and a composite catalyst are taken as raw materials, and are polycondensed with polypropylene glycol and the remaining polyethylene glycol to form the polyester-polyether copolymerized moisture absorption and sweat releasing finishing agent after ester-interchange reaction. The method is high in synthesis efficiency, the finished fabric is good in hydrophilicity, high in comfort, excellent in washing resistance, the antistatic property and the decontaminability are obviously improved, and the problem that a traditional moisture absorption and sweat releasing finishing agent is poor in washing resistance generally is solved.

Description

technical field [0001] The invention relates to the technical field of moisture-absorbing and sweat-wicking finishing agents for polyester fabrics, in particular to a method for preparing a moisture-wicking and sweat-wicking finishing agent that is applied to polyester fabrics and has excellent washability. Background technique [0002] Synthetic fibers have excellent properties that natural fibers cannot match, especially the most widely used polyester fiber (polyester). It has high mechanical strength, heat and light resistance, good chemical stability to acids, oxidants, reducing agents and organic solvents, and it is crisp and smooth after being made into clothes. However, due to the absence of hydrophilic and hygroscopic groups in the molecular structure, the degree of swelling in water is small, and the dry and wet strengths and elongation at break are basically the same. It shows strong electrostatic and dirt-absorbing properties in the use of clothing or decorations....
