Problems solved by technology

[0009] Patent application "method for changing color of fabric and color-changing fabric" (application number: CN201010148231.9, publication number: CN101817251A), which is to coat a layer of color-changing ink on the surface of the fiber thread of the fabric, so that the fabric can be changed according to the environment. The disadvantage is that the color-changing ink is not microencapsulated, and the combination or cross-linking with the fiber is poor, the color-changing ink is easy to remove, and the service life is short

[0065] Thermochromic dyeing of fabrics

[0066] Fabric: fabric blank (fabric after annealing, boiling and bleaching treatment) specifications: cotton plain cloth, 32x32 / 68x68.

[0067] Preparation of thermosensitive color-changing dye microcapsules:

[0068] Thermochromic dye (leuco dye, developer and sensitizer) composition:

[0069] Leuco dye / developer / sensitizer: Crystal Violet Lactone (CVL) / Stearic Acid / Myristyl Alcohol: 1 / 2 / 30.

[0070] (1) Preparation of heat-sensitive color-changing dye: Weigh 50 g crystal violet lactone, 100 g stearic acid and 1500 tetradecyl alcohol in a mass ratio of 1 / 2 / 30 into a container with a stirrer, heat up with a water bath Temperature is about 80°C, stirring and reacting for 30-60 minutes, and the heat-sensitive color-changing core material is obtained.

[0071] (2) Preparation of microcapsules:

[0072] Accurately weigh 55g of chitosan (wall material A) and full...

Abstract

The invention discloses a temperature-sensitive color-changing paint dyeing technology of textile fabrics. The process flow is as follows: selection and composition of the temperature-sensitive color-changing paint; preparation of temperature-sensitive color-changing dye microcapsules; preparation and dyeing of a temperature-sensitive color-changing pigment printing paste, dehydration, and baking to obtain a temperature-sensitive color-changing fabric. The textile fabric is a fabric which is prepared by pretreatment of cotton, Tencel fiber, modal fiber, chemical fibre blended cotton (lanca, polyester cotton and nylon cotton), silk, wool and the like. Through combined actions of ambient temperature, temperature inside clothes and body temperature, the color of the temperature-sensitive color-changing textile obtained by the application of the dyeing technology changes when the surface temperature of the textile achieves or exceeds color-changing temperature; and when the temperature drops below the color-changing temperature, the textile turns to the original color. With the change of the temperature, the textile fabric shows unexpected color and pattern, and the pattern will change based on movement of the body. The color-changing fabric can be widely applied in T-shirt, trousers, swimsuit, casual gym suit, working clothes, children's clothing, curtain, toy and the like.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive color-changing paint dyeing in the textile manufacturing industry, in particular to textile fabrics made of cotton, tencel, modal, chemical fiber blended cotton (viscose cotton, polyester cotton, nylon cotton), silk, and wool cotton after pretreatment Fabric heat-sensitive color-changing paint dyeing process. Background technique [0002] Color-changing fiber is a new type of high-tech fiber, which has broad application prospects in industry and daily life. Japan, the United States and other countries have already invested a lot of manpower and material resources to research and develop such fibers and textiles. The current competition in the field of synthetic fibers in the world has shifted from the expansion of output to the development of new products with high quality and high added value. Research and development of functional fibers and textiles with color-changing effects have goo...
