Problems solved by technology

But the invention only changes color in three or four stages, the color is too single, and the color change is not sensitive at the same time
[0008] CN10233.363A discloses a temperature-sensitive printing color paste and temperature-sensitive color-changing clothing, wherein the temperature-sensitive printing color paste includes: 79wt%-83wt% printing white paste, 15wt%-19wt% printing transparent paste and 1wt% %-3wt% temperature-sensitive pigment; the printing transparent paste is a water-based epoxy resin printing transparent paste, the temperature-sensitive printing paste can have sensitive and stable color changes at 20°C-40°C, and can be printed according to clothing To determine the approximate temperature of the environment, and then actively choose to add or remove clothing to ensure that the body is in the most comfortable and healthy state at all times. However, the temperature-sensitive printing paste has high formaldehyde content and poor safety, so it is not suitable for infants and young children.

Abstract

The invention discloses temperature-sensitive printing paste, which is prepared from the following raw materials in parts by weight: 0.5 to 3 parts of a binder, 0.5 to 19 parts of a temperature changematerial, 10 to 50 parts of a crosslinking agent and 2 to 5 parts of a thickener. Meanwhile, the invention further provides a temperature-sensitive color printing process, comprising the following steps: S1, slurrying: uniformly mixing the binder, the temperature change material, the crosslinking agent and the thickener to obtain the temperature-sensitive printing color paste; S2, bleaching and dyeing; S3, setting before printing; S4, printing: feeding the temperature-sensitive printing paste obtained in the step S1 into a screen, and covering cloth by the temperature-sensitive printing pasteto obtain printed cloth C; S5, drying and baking: drying and baking the printed cloth C. The temperature-sensitive printing paste has the beneficial effects that the temperature-sensitive printing paste is high in safety and high in color change sensitivity; the printing process is simple; the color of the prepared color change cloth sensitively changes with temperature, and the color change cloth is firm in color, high in safety and suitable for being used in infant products.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a temperature-sensitive printing color paste and a printing process thereof. Background technique [0002] With the development of disciplines and the cross-application of various disciplines, printing technology has been widely used in fabric printing and dyeing. High-tech materials and special printing fabrics with special functions of various perceptions, touches and smells are dazzling, which enrich people's quality of life and meet the special needs of various behaviors. Special printing meets the needs of the times, and reflects the progress of printing technology, which is an inevitable trend of today's printing technology progress. [0003] Temperature-sensitive color-changing printing, also known as heat-sensitive color-changing printing, refers to the phenomenon that a substance changes color at different temperatures. There are many reasons fo...
