Preparation method for microcapsule-coated insecticide controlled release textile

Abstract

The invention relates to a preparation method for a microcapsule-coated insecticide controlled release textile. According to the method of preparing the microcapsule-coated insecticide controlled release textile by utilizing a microcapsule technology and a mode of blend melt spinning, pesticide such as an insecticide can accurately and uniformly permeate into fibers through the mode of blend meltspinning, the insecticide and a synergist are microencapsulated, so as to realize slow release in a polymer matrix, the particle size and the core-wall ratio of a microcapsule particle are further controlled to realize proportional release of the insecticide and the synergist, ensuring that the effective components of the textile subjected to washing can still migrates onto the surfaces of the fibers from the interiors, even if the number of washing times is increased, the effective components of the insecticide and the like can still reach relatively large release quantity, and finally, thetextile with better and durable mosquito prevention and killing effects. The method is simple and easy, and the controlled release of the insecticide can be maintained even after 20 washings, thus achieving the anti-mosquito and anti-mosquito effect.

Description

technical field [0001] The invention relates to a preparation method of microcapsule-coated insecticide controlled-release textiles. The microcapsule-coated insecticide can be integrated into a polymer matrix to protect humans and animals. Background technique [0002] More than half of the world's people live under the threat of mosquito-borne diseases. Mosquitoes spread diseases through contact with human blood. As a vector-borne disease, malaria caused by this has complex epidemic factors and has the characteristics of fast and easy transmission. Recurring characteristics and therefore a constant threat to human health. On this basis, mosquito control work is of great significance. A variety of mosquito control methods have also emerged one after another, and with the continuous improvement and innovation of mosquito control and mosquito control methods, the spread of malaria in some countries and regions has been controlled to a certain extent, but due to the emergence ...

AI Technical Summary

Problems solved by technology

However, the anti-mosquito textiles obtained by post-finishing cannot guarantee the uniformity of the insecticide on the textile, nor can it guarantee that the active ingredients of the insecticide can penetrate into the interior of the textile efficiently

Insecticides are easily washed off on the surface of textiles, and anti-mosquito textiles have poor washability

At the same time, the microcapsule anti-mosquito finishing liquid used for coating or impregnation is only based on the characteristics of the microcapsule itself in the process of controlling the slow release of insecticides. The specific controllable release mechanism has not been studied in detail, so it cannot be used. Realize the controlled release of insecticides, and then realize the long-term anti-mosquito effect. The so-called anti-mosquito effect will also weaken with the increase of washing times, and the anti-mosquito durability is often not as good as the textile effect obtained by the blending method.
