Embodiment 1

[0022] A preparation method for self-cleaning functional down, comprising the following steps:

[0023] (1) Preparation of photodegradation system: Weigh 50g of sulfonated polyether ether ketone and dissolve it in 500ml of water, heat it to 50°C in an ultrasonic environment to accelerate dissolution; weigh 30g of silk fibroin polypeptide powder (particle size 50μm, purity greater than 95%) Dissolve in 500ml of cold water and fully swell for 3 hours, then heat to 70°C to dissolve. Under the condition of 70°C, the two solutions were fully stirred and mixed, and HCl was added to control the pH to 5.5 to prepare a photodegradation system;

[0024] The preparation method of sulfonated polyether ether ketone is: dry polyether ether ketone (Victrex, 450G) pellets at 100°C under vacuum for 6h, then weigh 4g and dissolve in 200mL concentrated sulfuric acid (98%) at 50°C , the rotation speed is 400r / min, stir vigorously for 15min, pour the reaction solution into 8 times the volume of i...

Embodiment 2

[0028] A preparation method for self-cleaning functional down, comprising the following steps:

[0029] (1) Preparation of photodegradation system: weigh 50g of sulfonated polyetheretherketone and dissolve it in 500ml of water, heat it to 50°C in an ultrasonic environment to accelerate dissolution; weigh 20g of silk fibroin polypeptide powder (particle size 50μm, purity greater than 95%) Dissolve in 500ml of cold water and fully swell for 3 hours, then heat to 80°C to dissolve. At 80°C, the two solutions were fully stirred and mixed, and HCl was added to control the pH to 5.5 to prepare a photodegradation system;

[0030] The preparation method of sulfonated polyether ether ketone is as follows: dry polyether ether ketone (Victrex, 450G) pellets at 100°C under vacuum for 6h, then weigh 4.5g and dissolve them in 200mL concentrated sulfuric acid (98%) at 50°C In the middle, the rotation speed is 400r / min, vigorously stirred for 15min, the reaction solution is poured into 7 time...

Embodiment 3

[0034] A preparation method for self-cleaning functional down, comprising the following steps:

[0035] (1) Preparation of photodegradation system: Weigh 70g of sulfonated polyether ether ketone and dissolve it in 500ml of water, and heat it to 50°C in an ultrasonic environment to accelerate dissolution; weigh 56g of silk fibroin polypeptide powder (particle size 50μm, purity greater than 95%) Dissolve in 500ml of cold water and fully swell for 3 hours, then heat to 70°C to dissolve. Under the condition of 70°C, the two solutions were fully stirred and mixed, and HCl was added to control the pH to 5.5 to prepare a photodegradation system;

[0036] The preparation method of sulfonated polyether ether ketone is: dry polyether ether ketone (Victrex, 450G) pellets at 100°C under vacuum for 6h, then weigh 4g and dissolve in 200mL concentrated sulfuric acid (98%) at 50°C , the rotation speed is 400r / min, stir vigorously for 15min, pour the reaction solution into 8 times the volume ...

Abstract

The invention provides a method for preparing down feather with a self-cleaning function. The method comprises the following steps: (1) constructing a light degradation system by using sulfonated polyetheretherketone and polypeptide; (2) soaking and dehydrating; and (3) spraying a water-repellant and oil-repellant finishing agent to prepare the down feather with the self-cleaning function. The surface of the prepared down feather is coated with a layer of sulfonated polyetheretherketone / polypeptide powder film and water-repellant and oil-repellant components. The water-repellant and oil-repellant components are used for preventing most pollutants from staining the down feather. Even if the down feather is stained by pollutants, the sulfonated polyetheretherketone / polypeptide powder film can form active free radicals under the irradiation of ultraviolet light, organic pollutants on the down feather are degraded by using the photocatalytic performance of the active free radicals, and pollutants is eliminated, so that the self-cleaning function is realized. The down feather with the self-cleaning function prepared by using the method is not wetted when being soaked into tap water for 72 hours, and is not wetted when being soaking into salad oil for 48 hours; the degradation rate of the simulated pollutant of methyl orange is over 60 percent, and the light degradation effect is not lowered after five times of water washing.

Description

technical field [0001] The invention belongs to a method for treating down, in particular to a method for preparing down with self-cleaning function. Background technique [0002] Down products are favored by the market and consumers because of their unparalleled natural fiber advantages and unique fluffy and warm performance. [0003] During the use of down products, sweat and other dirt come into contact with the down, causing the down to become moldy, smelly, and the microorganisms exceed the standard; rinsing the down products will damage the fluffy performance and warmth retention of the down; and a small amount of pathogens carried by the down itself In the rinsing process, it is difficult to eradicate, which affects the comfort of down products. Especially in public down products in hotels, the phenomenon of bacterial growth is more obvious. [0004] How to provide the society with continuous antibacterial, anti-virus, environmental protection and ecological down pr...
