Description

Aiye oil microcapsule antibacterial anti-wrinkle fabric and preparation method thereof

The invention relates to an anti-wrinkle fabric of a eucalyptus oil microcapsule and a preparation method thereof. Background technique

Microencapsule is a semi-permeable or hermetic microcapsule with a polymer wall shell that can embed and protect certain substances. Microcapsule technology uses natural or synthetic polymeric materials (often referred to as wall materials) to encapsulate dispersed solid material particles, droplets or gases (often referred to as core materials) in a film to form tiny capsules. A technique in which the diameter is generally from 1 to 1000 μm. Microcapsules have many unique functions, such as protecting the core material from environmental influences, reducing toxicity, masking bad taste, controlling core release, prolonging the effect of the drug, extending the storage period, changing the state of matter for portability and transportation, and changing the physical properties. Incompatible ingredients are evenly mixed and other functions. These special features make microcapsule technology widely used in many industrial fields such as medicine, food, pesticides, materials, coatings, inks, adhesives, cosmetics, detergents, photographic materials, and textile finishing. Ai Ye is one of the commonly used medicines in traditional Chinese medicine. It is the dry leaf of the perennial herb Ai. Ai Ye, as a commonly used traditional Chinese medicine with a long history in China, has been receiving attention for thousands of years. The main active ingredient of Artemisia argyi is volatile oil, which is eucalyptus oil. A large number of pharmacological studies have proven that Ai Ye oil has antibacterial, antiviral, antitussive and antitussive, enhanced cellular immune function, hemostasis and anticoagulation, anti-allergic, sedative, liver and gallbladder, complement activation and other effects, especially It has inhibitory effects on Streptococcus pneumoniae, Staphylococcus aureus, Escherichia coli, Respiratory syncytial virus, and influenza virus. In addition, Ai Ye oil is also widely used in the treatment of rheumatic pain. Sun Zhujuan of Chengdu University of Traditional Chinese Medicine has treated the volatile oil of Artemisia argyi with heat and penetrated into relevant acupuncture points to treat rheumatoid arthritis, which further proves that the volatile oil of Artemisia argyi in rheumatoid arthritis During the treatment, it can improve the effect of acupuncture on improving joint pain, controlling the condition and improving the joint function and quality of life of patients. According to literature reports, the treatment of rheumatoid arthritis with volatile oil of Artemisia argyi provides a new way for clinical treatment of such chronic autoimmune diseases. It can be seen from the above that Ai Ye oil has many functions such as antibacterial, anti-allergic, anti-allergic and promoting blood circulation. However, Aiye oil has strong volatility, strong odor, unstable active ingredients, easy loss, and inconvenience in storage, transportation and various dosage forms. It limits its scope of application. In recent years, with the improvement of people's living standards, people have become more and more demanding for the comfort and functionality of textiles. Textile finishing has become one of the important ways to improve the added value of products and improve the function of textiles. The use of microcapsule technology to make textiles have special functions is currently a hot spot. Various fabric finishing agents can be used as microcapsules for post-finishing of fabrics, such as aroma, flame retardant, antibacterial, deodorant, thermal storage, hair removal, anti-virus, anti-fog, anti-fouling, anti-wrinkle, anti-shrinkage, Soft, UV resistant, etc. The application of microcapsule technology in textiles is mainly in the printing and finishing, most of which are applied to fibers or fabrics by coating or blending, but in the coating, the microcapsules and the fabric only pass the adhesive. The physical adhesion, the washability, breathability and comfort performance are not at a practical level. Such as the impregnated microcapsule fabric provided by Chinese patent CN 85100799 A and the inorganic coated nano-silver antibacterial composite polyurea microcapsule anti-mosquito fabric provided by Chinese patent CN 1966849A.
