Technical Field

The invention belongs to the technical field of textile fabrics, and particularly relates to a fabric finishing liquid and application thereof in fabric preparation.

Background

The traditional warm-keeping mode is to prevent heat convection and control heat conduction by increasing the thickness of clothes, thereby achieving the warm-keeping effect, but the warm-keeping property of the traditional warm-keeping mode cannot be automatically adjusted along with the change of the environment, and along with the gradual improvement of the aesthetic level of people, the warm-keeping mode for increasing the thickness of the clothes is not accepted by people. Development of light, thin and comfortable thermal fabrics is an important way to solve the contradiction between thermal insulation and light and thin of clothes.

At present, the main method for preparing the warm-keeping textile achieves the warm-keeping effect by improving the textile structure or coating a metal coating on the textile [ ACS appl. However, the textiles prepared by the methods have poor air permeability and water resistance, low softness and unsatisfactory heat preservation effect. In addition, the thermal textile is used as a necessity of human life, and is easy to adsorb and contaminate microorganisms due to the loose porous structure of the thermal textile, and the metabolism of human body can secrete sweat and grease, thereby creating favorable conditions for the breeding and proliferation of microorganisms and directly influencing the health of human beings [ Journal of Colloid and Interface Science,2020,582, 112-. Therefore, the development of comfortable, warm-keeping and antibacterial fabric has important significance for the development of the modern textile industry.

The invention aims to develop a warm-keeping antibacterial fabric finishing liquid and an application method thereof in fabric preparation. The application of the fabric finishing liquid in the preparation of the fabric is as follows: and uniformly coating the fabric finishing liquid on the surface of the fabric through a foam applicator, drying and cooling to room temperature, coating a layer of fluorocarbon resin on the surface of the fabric, and finally performing vacuum drying. The fabric obtained by the method has good warm-keeping effect, is soft and comfortable, and has air permeability, water resistance and antibacterial performance, and has wide application prospect in the field of textile fabrics.
