preparation example Construction

[0029] Preparation of finishing agents. The finishing agent is obtained by dissolving polydopamine-coated vanadium dioxide composite powder in deionized water. The mass percent of the polydopamine-coated vanadium dioxide composite powder in the finishing agent can be 0.2-1 wt%.

[0030] Submerge the pretreated textile substrate in the finishing agent for 0.5 to 5 hours, so that the textile can fully absorb the finishing agent, and make the functional particles adhere to the textile fiber. After taking it out, roll it repeatedly with a rolling wheel, and keep the liquid rolling rate at 70% to 90%. Repeat this step 2 to 3 times to obtain the textile after natural drying.

[0031] Pretreatment of textile substrates. The textile substrate is put into a sodium hydroxide solution with a mass fraction of 5-15%, treated in a water bath at 50-100 DEG C for 30-120 minutes, washed and dried to obtain a pre-treated textile substrate. The textiles obtained after the pretreatment remove...

Embodiment 1

[0034] A manufacturing process of polydopamine-coated vanadium dioxide composite powder-based intelligent temperature-regulating textiles:

[0035] Using vanadium dioxide and polydopamine with a mass ratio of 1:2 to prepare polydopamine-coated vanadium dioxide nanocomposite powder, and then dissolve it in deionized water to prepare a finishing agent with a concentration of 0.2wt%;

[0036] Cotton cloth is pretreated with sodium hydroxide;

[0037] Use a shaker to immerse 6-8g of the pre-treated textile substrate into the finishing agent, take it out, and roll it repeatedly with a rolling wheel to keep the liquid rolling rate at 70%-90%;

[0038] Repeat the "immersion-rolling" process 2 times (two dipping and two rolling);

[0039] The treated textiles are naturally dried to obtain polydopamine-coated vanadium dioxide-based functional textiles.

[0040] Compared with the pre-treated textiles, the part with increased mass should be the polydopamine-coated vanadium dioxide comp...

Abstract

The invention relates to polydopamine-coated vanadium dioxide composite powder based intelligent temperature-regulating textile and a manufacturing process thereof. The textile comprises a textile base and polydopamine-coated vanadium dioxide composite powder attached evenly to the surface of fibers of the textile base. The preparation and application of the polydopamine-coated vanadium dioxide composite powder based intelligent temperature-regulating textile are studied herein, the textile has good synergy, including temperature control, breathability and durability; meanwhile, through polydopamine coating, oxidation time of vanadium dioxide is greatly shortened.

Description

technical field [0001] The invention belongs to the field of textile materials, and specifically relates to a polydopamine-coated vanadium dioxide composite powder-based intelligent temperature-regulating textile and a manufacturing process thereof. Background technique [0002] With the continuous improvement of the social level, people's requirements for clothing fabrics are not limited to warmth and shading, but higher requirements for its functionality and physiological comfort. In today's society, more and more people are facing the dilemma of working in a severe temperature environment, which prompts us to accelerate the development and application of intelligent temperature-controlling textiles. Early research was temperature regulation through the circulation of liquid and air. However, this temperature control, which relies on a large amount of energy and self-assembled processors, not only makes the textile production process cumbersome and difficult to clean. The...
