Abstract
Description
Technical Field
[0001] The present application relates to the technical field of down processing, and in particular to anti-allergic down, a preparation method and application thereof. Background Art
[0002] In recent years, down products have become more and more popular among consumers for their excellent light weight and warmth. Whether in the field of clothing or home textiles, the market for down jackets, down quilts, down pillows and other products is growing, and consumers are more and more accepting of them. However, the existing raw materials for down products do not have antibacterial function, and they are prone to cause allergies during wearing and use.
[0003] Therefore, there are many anti-allergic down products on the market. They mainly add antibacterial agents to the down to make the down have certain antibacterial properties, thereby reducing allergies.
[0004] Current antibacterial down is generally prepared by grafting groups with antibacterial properties on the surface of the down, or directly adding inorganic antibacterial agents to the surface of the down, etc.; the former will reduce the fluffiness of the down, and the antibacterial agent in the latter will easily fall off; therefore, it is necessary to prepare an anti-allergic down with good antibacterial properties, antibacterial agents that are not easy to fall off, and long-lasting antibacterial properties. Summary of the invention
[0005] In order to solve at least one of the above technical problems, an anti-allergic down with good antibacterial effect and long-lasting antibacterial performance is developed. The present application provides anti-allergic down, a preparation method and an application.
[0006] On the one hand, the present application provides an anti-allergic down, comprising down, attapulgite, nanosilver and graphene oxide, wherein:
[0007] Every 100g of down contains:
[0008] Attapulgite 2-8g;
[0009] Nanosilver 0.01~0.1g;
[0010] Graphene oxide 0.05~0.2g.
[0011] Optionally, the weight ratio of the nanosilver to graphene oxide is 1:1.8-3.
[0012] Optionally, the weight ratio of the total weight of the nanosilver and graphene oxide to the attapulgite is 1:30-40.
[0013] Optionally, the particle size of the attapulgite is 0.2 to 1 μm.
[0014] Optionally, the graphene oxide has a diameter of 0.01 μm to 15 μm, a thickness of 0.55 nm to 3.85 nm, a layer number of <10, and >99% wt.
[0015] In a second aspect, the present application provides a method for preparing the above-mentioned anti-allergic down, comprising the following steps:
[0016] S1, preparing a solution of attapulgite, adding nanosilver, stirring and mixing, and obtaining a mixed solution;
[0017] S2, adding graphene oxide to the mixed solution prepared in S1, stirring and mixing, and evaporating to dryness to obtain a mixture;
[0018] S3, preparing the mixture obtained in S2 into a solution, and immersing the down in the solution, first evaporating the solution to dryness, and then drying the down.
[0019] Optionally, in S3, the evaporation temperature is set at 60-80°C.
[0020] Optionally, in S3, the drying temperature is set at 30-50°C.
[0021] On the third aspect, the present application provides the application of the above-mentioned anti-allergic down in the fields of clothing and home textiles.
[0022] In summary, the present invention includes at least one of the following beneficial technical effects:
[0023] 1. The present application adds attapulgite, nanosilver and graphene oxide to compound antibacterial agents, and improves the binding force with down through the charged characteristics of attapulgite itself; and attapulgite has a certain hygroscopicity, which can firmly fix the nanosilver during the washing process, reducing the loss of antibacterial agents caused by washing and the decline in antibacterial effect; graphene oxide can effectively improve the movement of electrons between down, attapulgite and nanosilver, which can promote the movement of silver ions in attapulgite, making it easy to contact with bacteria and improve the antibacterial performance of nanosilver; and can strengthen the binding force between attapulgite and down;
[0024] 2. By limiting the particle sizes of attapulgite, nanosilver and graphene oxide, nanosilver and graphene oxide can be effectively fixed in the narrow channels of the attapulgite itself. Part of the graphene oxide is completely embedded in the channel, part is semi-embedded, and part is outside the channel of the attapulgite, so that silver ions and electrons can move quickly in the channel of the attapulgite, thereby improving the antibacterial performance.
