Technical Field

The invention belongs to the technical field of textile materials, and particularly relates to an environment-friendly antibacterial anti-mite Chinese yew flocculus and a preparation method thereof.

Background

The wadding is loose filling, and the garment must be added with lining (some also need lining bladder), and quilted by machine or hand. As an important auxiliary material in the textile industry, the traditional flocculus uses silk, cotton, terylene and the like as raw materials, and the performance of the single-material flocculus is too single, so that the defects are obvious, for example, the silk is soft and comfortable, but the silk is expensive and not durable; the cotton has good heat retention property, but is easy to mildew and harden; the terylene has the advantages of high differentiation of cheap performance, low moisture regain, air impermeability and easy bacterial breeding of the traditional fiber. Although composite flocculus with the functions of keeping warm, degrading, conducting moisture, quickly drying and the like is developed gradually, most of the current functional fibers take terylene as a substrate. As a non-renewable resource, terylene may cause environmental pollution while the resource may be exhausted. At present, metal ions, nano catalytic bactericides (including titanium dioxide, silicon dioxide and the like), negative ions and other antibacterial agents are generally integrated on fibers to increase antibacterial property, but the heavy metal ions have strong ecological toxicity and are harmful to human bodies; the nano catalytic bactericide has poor washing fastness; the negative ion treatment is expensive.

Taxol contained in Taxus chinensis has unique anticancer mechanism and high anticancer activity, can prevent propagation of cancer cells and inhibit migration of tumor cells, and is known as the most important anticancer active substance in the field of natural medicines at present. A large amount of Chinese yew wood is left after the taxol is extracted from the Chinese yew, which causes resource waste. In recent years, yew trees are also gradually developed into regenerated cellulose to be applied to textiles. Although the natural antibacterial mite-killing cotton wadding has natural antibacterial mite-killing effects, high spinnability and smooth and comfortable hand feeling, the cotton wadding is too soft and has poor fluffiness as the cotton wadding, and the cotton wadding is difficult to be independently prepared.

In conclusion, the existing flocculus has the problems of poor antibacterial effect, poor durability, harm to the body, poor fluffiness of taxus chinensis flocculus, poor formability and the like.
