Abstract

The invention relates to a method for preparing a mugwort leaf oil microcapsule antibacterial crease-resistant fabric. The method comprises the following steps of: 1) emulsifying mugwort leaf oil in an emulsifying agent made of wall material; 2) performing complex coagulation reaction on the emulsified mugwort leaf oil; 3) cross-linking and curing the emulsion after the complex coagulation reaction to obtain mugwort leaf oil microcapsule emulsion; 4) adding crease-resistant cross linker, catalyst and penetrating agent into the obtained mugwort leaf oil microcapsule emulsion to prepare a mugwort leaf oil microcapsule antibacterial crease-resistant fabric finishing agent; and 5) treating the fabric by using the prepared mugwort leaf oil microcapsule antibacterial crease-resistant fabric finishing agent to obtain the mugwort leaf oil microcapsule antibacterial crease-resistant fabric. The invention also relates to the mugwort leaf oil microcapsule antibacterial crease-resistant fabric prepared by using the method. The mugwort leaf oil microcapsule antibacterial fabric has antibacterial and anti-inflammatory functions, meanwhile has crease-resistant and ironing-free functions, and has good washing fastness.

Description

technical field [0001] The invention relates to an antibacterial and anti-wrinkle fabric with mugwort leaf oil microcapsules and a preparation method thereof. Background technique [0002] A microencapsule is a semipermeable or hermetically sealed microcapsule with a polymer wall that can embed and protect certain substances. Microcapsule technology is the use of natural or synthetic polymer materials (usually called wall materials) to encapsulate dispersed solid material particles, liquid droplets or gases (usually called core materials) in a film to form tiny capsules. A technology whose diameter is generally 1 to 1000 μm. Microcapsules have many unique functions, such as protecting the core material from the environment, reducing toxicity, masking bad taste, controlling the release of the core material, prolonging the efficacy, prolonging the storage period, changing the physical state for easy portability and transportation, and changing physical properties to make it e...
