Description

Technical Field

[0001] The invention belongs to the technical field of down processing, and in particular relates to a long-acting slow-release goose down anti-mite processing process. Background Art

[0002] Because there are a large number of tiny pores between goose down fibers, these pores can capture air and form an insulating layer, which effectively limits heat loss and provides excellent thermal insulation effect. Goose down is widely used in the production of high-end down jackets, down quilts, sleeping bags and other thermal insulation products due to its excellent warmth retention, breathability, lightness and comfort. It can also be used to manufacture some high-end household items, such as pillows and cushions.

[0003] Some high-end goose down products can further enhance their anti-mite effect through physical or chemical methods, for example, using heavy metal-free organosilicon quaternary ammonium salts for chemical mite removal, or permanently fixing anti-mite and antibacterial active ingredients on the fiber. Although the anti-mite technology of goose down has made significant progress in recent years, there are still some shortcomings. The existing goose down products have a good anti-mite effect when they are first used, but in the long-term use process, due to the adaptability and reproductive capacity of dust mites, the anti-mite effect will gradually decrease, and the long-term sustained release performance is poor; and the anti-mite component has low adhesion on the goose down, which is easy to fall off or fail during use. After multiple washings, its anti-mite effect will be significantly reduced.

[0004] To this end, we provide a long-acting, sustained-release goose down anti-mite treatment process to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a long-acting and sustained-release goose down anti-mite treatment process in view of the problems of the background technology.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A long-acting slow-release goose down anti-mite treatment process comprises the following steps:

[0008] S1, dispersing the anti-mite treatment liquid in 10-12 times the mass of an ethanol solution with a volume fraction of 75%, then mixing the nano-scale pearl clay powder and stirring evenly, heating to 60-70° C. to obtain an anti-mite nanoemulsion;

[0009] S2, spraying the anti-mite nanoemulsion evenly onto the dry goose down, and then drying;

[0010] S3, repeating the step of S2, spraying at least two layers of anti-mite nanoemulsion on the goose down;

[0011] The raw materials for preparing the anti-mite treatment liquid include, by weight, 8-10 parts of tea tree essential oil, 8-10 parts of rosemary essential oil, 3-5 parts of microalgae extract, 2-3 parts of snake oil extract, 10-15 parts of bamboo vinegar, 0.5-1 parts of emulsifier, 0.5-1 parts of thickener and 40-50 parts of deionized water.

[0012] As a further optimization scheme of the present invention, the microalgae extract is obtained by treating Sargassum powder with phytic acid and graphene in sequence.

[0013] As a further optimization scheme of the present invention, the phytic acid treatment refers to: dispersing Sargassum powder with a particle size range of 10-50nm in a phytic acid aqueous solution with a volume fraction of 50% at 6-8 times the mass, adjusting the pH to 4-6, adjusting the temperature to 40-50°C, and then applying ultrasound with a frequency of 20-25KHz and a time of 15-20min to the dispersion, and then letting it stand for reaction for 1-1.2h to obtain an intermediate solution.

[0014] As a further optimization scheme of the present invention, the graphene treatment refers to: dispersing the graphene in an intermediate liquid of 12-15 times the mass, mixing evenly, applying ultrasound with a frequency of 15-20KHz and a time of 10-15min to the dispersion, and then spray drying to obtain the microalgae extract.

[0015] As a further optimization scheme of the present invention, the snake oil extract is obtained by treating red-chain snake oil with myristic acid, and the mass ratio of the red-chain snake oil to myristic acid is 1:2-3.

[0016] As a further optimization scheme of the present invention, the myristic acid treatment refers to: dispersing red-chain snake oil and myristic acid in 8-10 times the mass of 95% ethanol solution, adding 0.5-1% myristic acid mass of catalyst wood vinegar, heating the mixture to 80-90°C under stirring, and maintaining the temperature for 1-2h, and separating and purifying after the reaction to obtain the snake oil extract.

[0017] As a further optimized solution of the present invention, the emulsifier is lanolin; the thickener is xanthan gum.

[0018] As a further optimization scheme of the present invention, the preparation steps of the anti-mite treatment liquid are: adding deionized water into a container, then gradually adding tea tree essential oil and rosemary essential oil and stirring evenly, then adding microalgae extract and snake oil extract and stirring evenly, then slowly adding bamboo vinegar and stirring evenly, then adding emulsifier and thickener and stirring evenly, finally applying ultrasonic waves with a frequency of 30-40KHz and a time of 20-30min, filtering through a filter, and the filtrate is the anti-mite treatment liquid.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention prepares the anti-mite treatment liquid by using microalgae extract and snake oil extract, and the anti-mite effect of the goose down after the treatment is significantly enhanced, and has the performance characteristics of long-acting sustained release. The anti-mite treatment liquid has good adhesion on the goose down, and the overall stability of the goose down is high.

[0021] 2. The treatment of Sargassum powder with phytic acid and graphene in the present invention can effectively enhance the anti-mite effect of goose down. Phytic acid is chelated and esterified with Sargassum powder to change the properties of Sargassum, so that the anti-mite components can be better adsorbed and dispersed. The nano-graphene increases the contact area between the treatment liquid and mites, improves the adhesion of the anti-mite treatment liquid, and the release of the anti-mite components is subject to certain restrictions, so that the anti-mite effect can be continuously exerted for a long time.

[0022] 3. The present invention treats common snake oil with myristic acid to further enhance the antibacterial and anti-mite effects of the anti-mite treatment liquid. Myristic acid, which has antibacterial activity itself, is compounded with snake oil to form new fatty acid derivatives to enhance its antibacterial and anti-mite effects. The carboxyl group of myristic acid reacts with the hydroxyl group of fatty acids in the snake oil to form an ester bond that can slow down the release rate of the anti-mite treatment liquid, thereby achieving a long-acting sustained-release effect.

[0053] Table 1. Raw material components for preparing anti-mite treatment liquid

[0054]

[0055]

[0056] Note: “-” means no addition; ordinary microalgae extract 1 refers to the traditional Sargassum powder that is not treated with phytic acid or graphene; ordinary microalgae extract 2 refers to the substance obtained by only treating Sargassum powder with phytic acid but not with graphene; ordinary snake oil refers to snake oil that is not treated with myristic acid.

[0057] Take several groups of goose down of the same mass (e.g. 100g), the treated sample: goose down treated with the anti-mite treatment liquid prepared in the embodiment and the comparative example, the control sample: goose down not treated with the anti-mite treatment liquid, and perform the following performance tests on the samples respectively:

[0058] (1) Anti-mite effect test:

[0059] The samples are placed in culture dishes, and a certain number (e.g., 150) of surviving mites are placed in the culture dishes. The mites may be dust mites, and then the culture dishes are placed in a constant temperature and humidity incubator for culture. After 24 hours, the number of surviving mites in each group of samples is counted, and the mite repellency rate is calculated based on the counting results to evaluate the anti-mite effect. Repellency rate = [(number of mites in the control sample - number of mites in the treatment sample) / number of mites in the control sample] × 100%. When the repellency rate is ≥60%, it means that the test sample has an anti-mite effect, when the repellency rate is ≥80%, it means that the test sample has a strong anti-mite effect, and when the repellency rate is ≥90%, it means that the test sample has an extremely strong anti-mite effect.

[0060] (2) Sustained release performance test:

[0061] Use an environmental chamber to simulate accelerated aging conditions, and accelerate the aging process of goose down by adjusting factors such as temperature, humidity, and light. For example, set the temperature to 40-50°C, the relative humidity to 70-90%, and give a certain intensity of ultraviolet radiation to simulate long-term outdoor exposure or environmental changes after long-term use. Similarly, prepare treated and control goose down samples, put them into the accelerated aging environmental chamber, and take out some samples for anti-mite performance test at different time points in the aging process (such as the 3rd day, the 1st week, the 2nd week, etc.) to evaluate the anti-mite slow-release performance of goose down.

[0062] (3) Washability test:

[0063] Prepare treated and control goose down samples, and after 50 washes, test the anti-mite performance of the samples.

[0064] Table 2 Performance parameters of treated samples

[0065]

[0066] 3. Results Analysis

[0067] 1. Combined with the above table, by comparing the test data of the goose down samples in Example 1, Example 2 and Example 3 with other goose down, it can be seen that the initial anti-mite effect, the anti-mite effect after aging and the anti-mite effect after washing of the goose down are significantly better than those of other down, indicating that the goose down has the performance characteristics of long-term sustained release, and the anti-mite treatment liquid has good adhesion on the goose down, and the overall stability of the goose down is high.

[0068] 2. Combined with the above table, by comparing the test data of the goose down sample of Comparative Example 1 and the goose down sample of Example 1, it can be seen that since the common microalgae extract 1 is added to the anti-mite treatment liquid of the goose down sample of Comparative Example 1, and the common microalgae extract 1 is the traditional Sargassum powder that is not treated with phytic acid and graphene, it shows that the phytic acid and graphene treatment of the Sargassum powder can effectively enhance the anti-mite effect of the goose down. This may be because phytic acid has a strong chelating ability and multiple phosphate groups, which can react with the ions in the Sargassum to undergo a chelating reaction, and at the same time, the phosphate groups and the hydroxyl groups of the Sargassum undergo an esterification reaction, thereby changing the surface charge and hydrophilicity of the Sargassum. In the anti-mite treatment liquid, the modified Sargassum can better adsorb and disperse the anti-mite components, and due to the chelation and esterification of phytic acid, the release of the anti-mite components is subject to certain restrictions, and the anti-mite effect can be continuously exerted for a long time.

[0069] 3. Combined with the above table, by comparing the test data of the goose down sample of Comparative Example 2 and the goose down sample of Example 1, it can be seen that since common microalgae extract 2 is added to the anti-mite treatment liquid of the goose down sample of Comparative Example 2, and the common microalgae extract 2 is Sargassum powder that is only treated with phytic acid and not treated with graphene, the anti-mite effect of the goose down samples of Comparative Example 1 and Comparative Example 2 after washing changes greatly, while the anti-mite effect of the goose down samples of Comparative Example 3 and Comparative Example 4 after washing does not change significantly, which indicates that the graphene treatment of Sargassum powder can effectively enhance the washing resistance of goose down, and the nanostructure of graphene may increase the contact area between the treatment liquid and mites, thereby improving the anti-mite effect, and can improve the stability of the treatment liquid, making it difficult to decompose or fail during use, enhancing the adhesion between the anti-mite treatment liquid and the goose down, and having better water washing resistance.

[0070] 4. Combined with the above table, by comparing the test data of the goose down sample in Comparative Example 3 and the goose down sample in Example 1, it can be seen that since ordinary snake oil is added to the anti-mite treatment liquid of the goose down sample in Comparative Example 3, and the ordinary snake oil is not treated with myristic acid, the anti-mite effect is greatly reduced, indicating that myristic acid treatment can enhance the antibacterial and anti-mite effect of ordinary snake oil. This may be because myristic acid itself has antibacterial activity. When introduced into snake oil, new fatty acid derivatives can be formed to enhance its antibacterial and anti-mite effects. The carboxyl group of myristic acid reacts with the hydroxyl group of fatty acids in snake oil to form an ester bond. Due to the presence of the ester bond, the release rate in the anti-mite treatment liquid will be slowed down, thereby achieving a long-acting sustained release effect.

[0071] 5. Combined with the above table, the comparison of the test data of the goose down samples of Comparative Examples 4 and 5 and the goose down sample of Example 1 shows that the combination of microalgae extract and snake oil extract can exert the synergistic effect of the two and enhance the performance of the material.

[0072] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
