Embodiment 1

[0035] Use 3-mercaptopropyltriethoxysilane KH-580 to modify cotton fabric, and react with water-based photocurable polyurethane acrylate to make cotton have good anti-wrinkle function. The specific steps are:

[0036] (1) Pre-processing:

[0037] ① Prepare a mixed solution of 20g / L sodium hydroxide and 5g / L Pingping plus O, and roughen the cotton fabric for 45 minutes at 70°C;

[0038] ② Prepare 5 wt% ethyl acetate solution of 3-mercaptopropyltriethoxysilane (KH-580), put the roughened cotton fabric into the above solution, and shake at 30°C for 3 hours;

[0039] ③Take out the cotton fabric, wash it with distilled water, and dry it under vacuum at 60°C.

[0040] (2) Finishing:

[0041] ① Prepare a mixed solution of 5wt% water-based polyurethane acrylate and 5wt% 3-mercaptopropyltriethoxysilane, ultrasonically oscillate, then add 1wt% photoinitiator, and ultrasonically oscillate;

[0042] ②Put the cotton fabric flatly in the above finishing solution, with a bath ratio of 1:50,...

Embodiment 2

[0044] Use 3-mercaptopropyltriethoxysilane KH-580 to modify cotton fabric, and react with water-based photocurable polyurethane acrylate to make cotton have good anti-wrinkle function. The specific steps are:

[0045] (1) Pre-processing:

[0046] ①Prepare 20g / L sodium hydroxide aqueous solution, 5g / L Pingping plus O, and roughen the cotton fabric for 45min at 70°C;

[0047] ② Prepare 5 wt% ethyl acetate solution of 3-mercaptopropyltriethoxysilane (KH-580), put the roughened cotton fabric into the above solution, and shake at 30°C for 3 hours;

[0048] ③Take out the cotton fabric, wash it thoroughly in distilled water, and dry it under vacuum at 60°C.

[0049] (2) Finishing:

[0050] ① Prepare a mixed solution of 10wt% water-based polyurethane acrylate and 5wt% 3-mercaptopropyltriethoxysilane, fully ultrasonically oscillate, then add 1wt% photoinitiator, and ultrasonically oscillate;

[0051] ②Put the cotton fabric flatly in the above finishing solution, with a bath ratio of...

Embodiment 3

[0053] Use 3-mercaptopropyltriethoxysilane KH-580 to modify cotton fabric, and react with water-based photocurable polyurethane acrylate to make cotton have good anti-wrinkle function. The specific steps are:

[0054] (1) Pre-processing:

[0055] ①Prepare 20g / L sodium hydroxide aqueous solution, 5g / L Pingping plus O, and roughen the cotton fabric for 45min at 70°C;

Abstract

The invention relates to a click chemistry-based cotton fabric durable anti-crease finishing method. The click chemistry-based cotton fabric durable anti-crease finishing method comprises the following steps: putting coarsened cotton fabric into a 3-thiopropyl triethoxy silane solution and performing sulfydryl modification to obtain sulfydryl modified cotton fabric; ultrasonically mixing photocurable waterborne polyurethane acrylate, sulfydryl silane and a photoinitiator to obtain finishing liquid; dipping the sulfydryl modified cotton fabric into the finishing liquid and performing ultraviolet curing to obtain the durable anti-crease cotton fabric. The method provided by the invention is simple in operation, high in efficiency, energy-saving and environmentally friendly; after finishing is conducted, the anti-crease effect is remarkable, the durability is high, and the influence on the whiteness of the fabric is little. After the cotton fabric is finished by the anti-crease process, the wearability can be improved, the application field can be enlarged, and the requirements of people on flat appearance and wear comfortability of clothes can be met.

Description

technical field [0001] The invention belongs to the field of cotton fabric functional finishing methods, in particular to a durable anti-wrinkle finishing method for cotton fabrics based on click chemistry. Background technique [0002] Cotton fiber products are one of the most popular fabrics because of their softness, breathability, moisture absorption, and comfortable wearing. Moreover, with the enhancement of people's awareness of returning to nature, natural fiber fabrics are favored by people again, but because there are a large number of hydroxyl groups on cotton fiber molecules, when subjected to external forces, the orientation degree of cellulose macromolecules or basic structural units increases or relative displacement occurs. After that, new hydrogen bonds can be re-formed at new positions. If the new hydrogen bonds are stabilized enough, the creep recovery rate is small, and permanent deformation occurs, that is, wrinkles are formed. Therefore, endowing cotto...
