Problems solved by technology

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. , Difficult to remove stains, poor hand feeling and other shortcomings, which are greatly restricted in use
[0003] At present, the finishing of polyester usually separates hydrophilic finishing and hand finishing, so it usually has the following disadvantages: long process time, low production efficiency; large amount of water and energy consumption, large carbon emissions; large amount of sewage, sewage difficult to handle

Embodiment 1

[0016] Synthesis of the moisture-absorbing and perspiring agent containing naphthalene structure: First, 70 g of polyethylene glycol was dehydrated, and the temperature was controlled at 100-105 °C for vacuum dehydration for 1 hour. After the dehydration is completed, 15g of dimethyl 1,8-naphthalenedicarboxylate, 15g of ethylene glycol, and 0.03g of zinc acetate are successively added to the reaction vessel equipped with a thermometer and a nitrogen tube, and the temperature is slowly raised under nitrogen protection for 25 to 30 minutes. When the temperature rose to 170°C, the temperature was controlled at 170-180°C for 4 hours.

[0017] After the transesterification is completed, continue to heat up to 190°C, control the temperature at 190-200°C and react for 30min, start vacuuming, and continue to heat up to 230°C, control the temperature at 220-230°C, and wait until the vacuum degree in the reaction vessel reaches -0.099MPa or more Timely heat preservation for 3 hours, and...

Abstract

The invention relates to a preparation method of a polyester fabric moisture-absorbing and sweat-releasing finishing agent containing a naphthalene structure, which comprises the following steps: by taking dimethyl 1, 8-naphthalate, ethylene glycol, polyethylene glycol and a catalyst as raw materials, carrying out transesterification, and then carrying out polycondensation to synthesize a polyester-polyether copolymerization type moisture-absorbing and sweat-releasing finishing agent suitable for polyester fabrics. The method is high in synthesis efficiency, the finished fabric is good in hydrophilicity and hand feeling, the moisture absorption and sweat releasing agent and silicone oil can be subjected to one-bath finishing, the hydrophilic performance is excellent after one-bath finishing, and the after-finishing efficiency of the fabric is greatly improved.

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-absorbing and sweat-wicking finishing agent that is applied to polyester fabrics and can maintain hydrophilic and washable properties when bathed with silicone oil. Background technique [0002] In addition to satisfying the basic functions of clothing fabrics, from the perspective of wearing comfort for the human body, if the sweat can be transferred and discharged in time, the clothes will not stick to the skin surface, making people feel hot and airtight, and enhancing the wearing comfort. especially important. Synthetic fibers have excellent properties unmatched by natural fibers, especially polyester, which accounts for more than 60% of synthetic chemical fibers. It has high breaking strength, high elastic modulus, good heat resistance, wear resistance, resistance and corro...
