Embodiment 1

[0023] A preparation method of a multifunctional moisture wicking finishing agent, comprising the following steps:

[0024] Step 1: drying polyethylene terephthalate at 103°C for 2h;

[0025] Step 2: add polyethylene terephthalate, polyethylene glycol and catalyst dried in step 1 into the reactor, fill with nitrogen to 0.1Mpa, and heat in an oil bath;

[0026] Among them, the mass ratio of polyethylene terephthalate: polyethylene glycol is 40~45:140~150

[0027] The catalyst is zinc acetate. The catalyst accounts for 0.04-0.08% of the total mass of polyethylene glycol and polyethylene terephthalate.

[0028] Step 3: When the temperature of the material in the reaction kettle reaches 150°C, turn on the mixer for stirring, continue heating, and when the temperature of the material reaches 275°C, vacuumize to -0.1Mpa, and then react at a constant temperature for 5h;

[0029] Step 4: after the reaction is completed, cool down to reduce the temperature to 220-230°C, then add hyd...

Abstract

The invention provides a multifunctional moisture absorption and sweat releasing finishing agent and a preparation method therefor. The method comprises the following steps of firstly, adding polyethylene glycol, polyethylene terephthalate and a catalyst into a reaction kettle, and performing stirring reaction at 275 DEG C for 5 hours; opening cooling water for cooling after the reaction is finished; adding hydrophilic silicone oil into the reaction kettle when the system temperature is reduced to 220-230 DEG C; and after heat preservation and stirring is performed for 1 hour, performing cooling and solidifying to obtain the targeted multifunctional finishing agent. The method is simple to operate, the multifunctional moisture absorption and sweat releasing finishing agent prepared throughthe method is good in hydrophilicity and high in washing resistance, also has the fluffy degree, the sliding degree and the softness, and has a very good antistatic function.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing auxiliaries, in particular to a multifunctional moisture-absorbing and perspiration-wicking finishing agent and a preparation method thereof. Background technique [0002] Moisture-wicking finishing agent refers to the use of special auxiliaries to functionally finish the fabric, so that the fabric has the characteristics of water absorption, moisture permeability and quick drying at the same time. Moisture-wicking finishing agents are generally used on polyester or polyester-cotton blended fabrics. Because its molecular structure has the same benzene ring as the polyester molecular structure, under the action of high temperature, the molecular segments are anchored on the surface of the polyester, so that the polyester is changed from the original hydrophobic surface to a durable hydrophilic surface, but due to the high temperature The water-repellent properties of the polyester com...
