Technical Field
The invention relates to a fabric, in particular to an antibacterial fabric, a production process thereof and a special spinneret plate.
Background
Fabric is the material used to make clothing. As one of the three elements of the garment, the fabric not only can explain the style and the characteristics of the garment, but also directly controls the expression effects of the color and the shape of the garment, and comprises a knitted fabric and a woven fabric.
Microcapsules, also known as microcapsules, are small particles that are coated, or the shell surrounds, a core material or a layer containing an active ingredient. Sometimes each microcapsule may contain some core material (either the same component, or different components). There is no known dimension of microcapsule size, and the diameter can be changed from 1-1000 μm, the color, shape, volume, mass, solubility and storage property of special core material can be changed after microencapsulation treatment, and under specific conditions, the core material can be released slowly to exert its function.
With the continuous development of science and technology, the microcapsule technology has attracted great attention, wherein the research on microcapsules and the application thereof on textiles is only about exposing the horn in recent years, but the development speed is rapid; and at the same time, its application in the antibacterial aspect of medical textile materials has led to extensive research and discussion in the scientific community. It can be said that the microcapsule technology has gradually entered the state of industrial development
The microcapsule core material is made of antibacterial substances, and the antibacterial microcapsules are attached to the surface of the fabric through the finishing liquid, so that the fabric has strong antibacterial capacity.
The preparation method of the leather fabric finishing agent disclosed in the Chinese patent with the publication number of CN109055633B has the technical key points that: extracting antibacterial components from radix et caulis Opuntiae Dillenii, and performing antibacterial and bactericidal treatment on leather; the mugwort essential oil is extracted from the mugwort, has good antibacterial effect but is easy to volatilize, the mugwort essential oil is wrapped by the microcapsules, the surface of the leather is sterilized and finished, and then the antibacterial liquid and the antibacterial microcapsules are permeated into the surface layer of the leather by the surfactant and the penetrant, so that the antibacterial liquid and the antibacterial microcapsules can be slowly released under the surface layer of the leather, and the antibacterial effect is greatly prolonged; the two antibacterial substances are extracted from natural plants, have good affinity to human skin, and are added with green tea leaves, so that the smell is improved, and the leather fabric has light green tea fragrance after being finished.
The fabric containing the antibacterial microcapsules has a common problem that: the antibacterial microcapsules are usually attached to the surface of the fabric in a finishing liquid dipping mode and are difficult to enter the fabric, and when the fabric is shaped, subjected to after-finishing and used, the antibacterial microcapsules can fall off from the surface of the fabric due to the friction of external articles of the fabric and the mutual friction of the fabric, so that the antibacterial period of the antibacterial microcapsules is greatly reduced
Therefore, a new solution is needed to solve this problem.
