Abstract

The invention discloses luminous printing colorant. The luminous printing colorant comprises the following components by mass: 1 parts of a rare earth luminous material, 0.25-1 part of a dispersing agent, 0.8-3 parts of a mesosome, 0.1-0.3 part of an initiator, less than or equal to 0.05 part of dyestuff, 0.8-2 parts of a waterborne adhesive and 0.1-0.5 part of a thickening agent, wherein the rareearth luminous material comprises one or more of Sr(NO3)2, Al(NO3)3.9H2O, Eu2O3 and Dy2O3. On the basis of features of printing of textile, the prepared colorant is applied to a textile fabric, printing fabrics and coating textile fabrics which contain the rare earth luminous material are prepared, the products have appearances and various properties of conventional textile printing and coating fabrics, and furthermore, printing patterns or a whole fabric can be luminous in a dark environment after being illuminated.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a luminous printing paste and a preparation method thereof. Background technique [0002] With the development of social economy, people's requirements for the styles, colors and styles of fabrics and clothing are constantly changing and improving, especially the improvement of people's living standards, and the taste of life has been greatly improved. For clothing fabrics, not only high comfort is required, but also more special functions are required. [0003] Luminescent materials are divided into two types: self-illuminating and storage-luminescent. The basic components of self-illuminating luminescent materials are radioactive materials, which do not need to absorb energy from the outside, and can continue to emit light regardless of night or day. Environmental protection requirements. The light-storing light-emitting materials are zinc sulfide light-em...
