Abstract

The invention belongs to the technical field of microcapsule preparation and spinning and discloses a cinnamon oil microcapsule fabric finishing liquid as well as a preparation method and application thereof. The preparation method comprises the following step: with a chitosan quaternary ammonium salt and Arabic gum as a wall material and cinnamon oil as a core material, preparing a cinnamon oil microcapsule emulsion through a complex coacervation method; and compounding the prepared microcapsule emulsion with an anti-wrinkling cross-linking agent, a catalyst and a penetrating agent to obtain the cinnamon oil microcapsule fabric finishing agent which comprises the following components in percentage by weight: 15%-30% of cinnamon oil microcapsules, 6%-12% of the anti-wrinkling cross-linking agent, 2%-3.5% of the catalyst, 0.5%-2% of the penetrating agent and the balance of water. A chemical cross-linking method is adopted to perform multifunctional finishing on fabric, and the cross-linking agent is used as a bridge for cross-linking the microcapsules with the fabric through chemical bonds, so that the finished fabric has relatively good washing resistance and relatively lasting antibacterial health and anti-winkling functions.

Description

technical field

[0001] The invention belongs to the field of microcapsule preparation technology and textile technology, and in particular relates to a cinnamon oil microcapsule fabric finishing agent and its preparation method and application. Background technique

[0002] Textiles are essential supplies in people's lives. However, all kinds of textiles are suitable places for the breeding and propagation of harmful bacteria, fungi, viruses and other microorganisms. The large number of pathogenic bacteria multiplying on textiles will not only make fiber products discolored, moldy, Degradation will spread diseases through indirect ways, causing harm to human life. With the increasing awareness of people's health care, people's demand for textiles with antibacterial function is becoming more and more urgent. Therefore, the research and development of antibacterial textiles is of great significance.

[0003] In the antibacterial textile industry, many antibacterial substances...
