Abstract

The invention discloses a thermochromic fabric and a preparation method thereof. The thermochromic fabric comprises a thermochromic layer and a base cloth layer which are connected with each other, The thermochromic layer comprises the following components in parts by weight: 60-70 parts of silk fibers, 34-50 parts of Lyocell bamboo fibers, 11-16 parts of a desensitizer, 15-20 parts of a firming agent, 26-30 parts of a dispersing agent, 17-25 parts of a wetting agent, 10-15 parts of a color fixing agent, 5-10 parts of an antioxidant, 10-15 parts of a color-changing dye, 10-17 parts of a disperse dye, 4-6 parts of bisphenol A and 4-9 parts of crystal violet lactone; and the base cloth layer is formed by weaving polyester yarns. The thermochromic fabric provided by the invention not only achieves the effect of different colors through color change under different light sources, but also is good in hand feeling, soft and comfortable, does not fade after being washed for multiple times, and achieves the effect of synchronization of aesthetic feeling and practicability.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a thermochromic fabric and a preparation method thereof. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. In the world of clothing, the fabrics used are varied and changing with each passing day. But in general, high-quality, high-end fabrics are mostly comfortable to wear, sweat-absorbent, breathable, drape and stiff, visually noble, and soft to the touch. [0003] Traditional clothing uses fixed colors and patterns to meet people's basic requirements for cold protection, warmth and decoration through cutting. With the improvement of people's living standards, the requirements for textile fabrics are getting higher and higher. The existing textile fabrics have a single fu...
