Problems solved by technology

[0004] However, if the amount of microcapsules added to textiles is small, the functionality cannot be guaranteed; if the amount of microcapsules added is increased, the textiles often have poor air permeability and unsatisfactory hand feel.
In addition, the structure of the fabric obtained by traditional microcapsule finishing is too simple, and the microcapsules are often exposed on the surface of the fabric. During washing, processing and use, the microcapsules are easily damaged and lost, and it will also cause various problems such as the decline in the functionality of the textile.
These problems greatly restrict the finishing of microcapsules and hinder the popularization and application of functional textiles and the development of technology.

Abstract

The invention relates to a functional microcapsule-finished composite fabric, comprising a fabric layer, a microcapsule layer and a third layer, wherein the microcapsule layer is composed of microcapsules which are uniformly dispersed between the fabric layer and the third layer like spots, the microcapsule comprises at least one or an arbitrary mixture of more than one selected from the group consisting of an aromatic microcapsule, a variable-color microcapsule, a phase change microcapsule, an antibacterial microcapsule, a drug-sustained-release microcapsule and a flame-retardant microcapsule, and the fabric layer, the microcapsule layer and the third layer are connected through an adhesive or connected via an adhesive film in a pressing compounding manner. According to the invention, on the premise that functionality of a textile is guaranteed, the structure of the composite fabric is improved, so air permeability and hand feel of the fabric are improved, and washability and wear resistance of the textile are enhanced in virtue of the composite fabric.

Description

technical field [0001] The invention relates to functional textiles, in particular to a composite fabric obtained by finishing functional materials. Background technique [0002] Microcapsules are an emerging functional material. Microencapsulation technology (Microencapsulation) is a technology in which trace substances are wrapped in polymer films, and is a micro-packaging technology for storing solids, liquids, and gases. The microcapsules prepared by this technology essentially encapsulate some functional materials in tiny containers with a particle size ranging from 1 to 1000 microns. As the carrier of functional materials, microcapsules can be easily incorporated into textiles, building materials, agriculture, and medical supplies due to their small size, which expands the application range and application methods of materials. For example, in the document "Journal of Shanghai Fisheries University" in 2006, No. 3, pages 375-379, "Research on the Preparation of Enrofl...
