Embodiment 1

[0041] Use 3-mercaptopropyltriethoxysilane KH-580 to modify polyester fabric and graphene oxide, and react with polyurethane moisture-absorbing and sweat-wicking finishing agent, so that polyester has good moisture-wicking and heat-conducting functions. The specific steps are:

[0042] (1) Finishing agent synthesis:

[0043] Use 5ml of acetone as solvent, 1% dibutyltin dilaurate (DBTDL) as catalyst, 0.01mol PEG-400, 0.02mol isocyanoethyl methacrylate at 80°C for 5 hours with mechanical stirring to obtain polyurethane moisture-wicking finishing agent.

[0044] (2) Fabric pretreatment:

[0045] ① Alkali weight reduction: Prepare 90g / L sodium hydroxide, 5g / L Pingping plus O mixed solution, and carry out alkali weight reduction on polyester fabrics for 45 minutes at 70°C;

[0046] ② Mercapto modification: prepare 5wt% 3-mercaptopropyltriethoxysilane (KH-580) mixed solution of ethanol / water (volume ratio 4:1), pH is 3-4, temperature is 25°C, Put 1 g of alkali-reduced polyester ...

Abstract

The invention relates to a polyester fabric moisture absorbing, sweat releasing and heat conducting finishing method based on click chemistry. The method comprises the following steps of preparing sulfydryl-modified polyester fabric, preparing sulfydryl-modified reduced graphene oxide, preparing finishing liquid and preparing moisture absorbing, sweat releasing and heat conducting polyester fabric. The method has the advantages that the pre-treated sulfydryl polyester fabric, the sulfydryl reduced graphene oxide and a polyurethane moisture absorbing and sweat releasing finishing agent are enabled to form firm chemical bonds through the click chemistry, so that the polyester fabric can obtain good moisture absorbing, sweat releasing and heat conducting performance; the operation is simple,a process is environmentally-friendly, energy-saving and efficient, and the wearability of the polyester fabric can be greatly improved; and the prepared moisture-absorbing and sweat-releasing polyester fabric has no influence on hand feeling and strength.

Description

technical field [0001] The invention belongs to the field of functional finishing of polyester fabrics, in particular to a method for moisture absorption, perspiration and heat conduction finishing of polyester fabrics based on click chemical reaction. Background technique [0002] Polyethylene terephthalate, commonly known as polyester, has excellent properties such as good shape retention, low price, high strength, good elasticity, easy washing and quick drying, so it is widely used in various fields. There are many varieties of polyester, which are widely used in clothing fabrics, bedding, outdoor products, decorative fabrics, textiles such as national defense and military industries, and other industrial products. In 1960, the world output of polyester fiber surpassed that of acrylic fiber, and in 1972, it surpassed that of nylon. At present, polyester fiber has the largest industrial scale and usage, and has become the largest variety in synthetic fibers. Its output has...
