Problems solved by technology

However, the temperature-sensing temperature of the temperature-sensing fabric is high, and the heat transfer is slow, which usually needs to be produced by external conditions, which has limitations; and the temperature-sensing discoloration cannot be caused by the change of the human body surface temperature, which limits the application value of the fabric to make clothes At the same time, flame retardancy is also one of the functions required by fabrics. Generally, the fabric is impregnated with flame retardants to produce this function. In actual life, the flame retardancy will be reduced due to repeated washing of the fabric; in addition, the air permeability It is also one of the properties required by the fabric, and it is necessary to ensure the comfort of the human body wearing clothes. However, in common composite materials, the use of adhesives, flame retardants and other substances will reduce porosity and air permeability

Abstract

The invention discloses a carbon fiber-based thermochromic fabric and a preparation method thereof. The thermochromic fabric comprises a thermochromic film and a basic fabric, wherein the thermochromic film is prepared from the following raw materials in parts by weight of 12 to 18 parts of polyethylene glycol, 35 to 45 parts of polyurethane, 5 to 8 parts of boron nitride nanosheets and 12 to 15 parts of thermochromic microcapsules. The thermochromic fabric has the beneficial effects that a thermochromic coating is encapsulated in a microcapsule formed by a polymer shell layer, so that the service life and the dispersion uniformity of the coating are effectively protected; reactive glyceryl borate is introduced into the shell layer of the microcapsule, so that the oxidation resistance is improved, pigment is inhibited from being oxidized, and meanwhile, the flame retardance is improved; the microcapsule is subjected to electrostatic spinning to form the film, so that the dispersity of the microcapsule on the fabric is improved; the humidity in the spinning process is controlled to form thicker nanofibers, so that a film layer has higher air permeability; and the basic fabric is pretreated, so that the adhesive force between the fabric and the film layer is increased, and an adhesive is not used.

Description

technical field [0001] The invention relates to the technical field of color-changing fabrics, in particular to a carbon fiber-based temperature-sensitive color-changing fabric and a preparation method thereof. Background technique [0002] With the acceleration of China's socialization process, people's quality of life is gradually improving, and there is an increasing demand for the versatility of clothing. For example, the color-changing function, which makes the fabric change color by light and temperature induction, increasing the fashion or concealment of the clothes. [0003] Among various sensing color-changing fabrics, thermochromic fabrics have been widely studied because they can simply control the color change through temperature. However, the temperature-sensitive fabric has a high temperature and slow heat transfer, which usually needs to be produced by external conditions, which has limitations; and it cannot produce temperature-sensitive discoloration throug...
