Abstract

The invention discloses a preparation method of an oxide / essential oil / emulsion particle composite particle for after-finishing of an article. The preparation method comprises the following steps of modifying a nanometer oxide by a silane coupling agent; absorbing the essential oil with the modified nanometer oxide as a core; and then polymerizing through miniemulsion to cover the nanometer oxide absorbing the essential oil on the surface, in order to obtain three-layer structural oxide / essential oil / emulsion particle composite particle. The prepared oxide / essential oil / emulsion particle composite particle greatly reduces the volatilization rate of the essential oil. The method has the advantages of small equipment investment, simple production process, stable product quality, etc.

Description

technical field [0001] The invention discloses a preparation method of oxide / essential oil / latex particle composite particles for finishing textiles, and belongs to the fields of fine chemical industry and material science. technical background [0002] Essential oil is a natural product composed of β-linalool, α-terpineol, eucalyptol, limonene and eugenol, and has antibacterial and antibacterial effects. Applying essential oils to textiles can not only endow textiles with good antibacterial properties and reduce the stimulating effect of synthetic antibacterial agents on the human body, but also make good use of renewable natural resources and realize the full utilization of renewable resources. However, because essential oils are highly volatile, they cannot be directly applied to textiles, so they need to be processed. [0003] Adopting the method of microencapsulation to encapsulate essential oil is one of the main means to reduce the volatilization speed of essential o...
