Description

Technical Field

[0001] This invention relates to a method for preparing an electron beam curable coating with high color depth and soft hand feel, and its application in textile coloring, belonging to the field of fine chemical technology. Background Technology

[0002] Traditional textile coloring and curing methods primarily involve thermal curing and photocuring. However, these methods have certain limitations. For example, the thermal curing process in ZL107938387B is time-consuming, energy-intensive, and has high production costs. Photocuring, on the other hand, utilizes ultraviolet (UV) light sources and is characterized by its speed and low energy consumption, as seen in ZL103788771B and ZL103788771B. However, light attenuation is closely related to the properties of the irradiated material, and light penetration is limited by light penetration ability. When the transparency of the material decreases, light penetration is hindered, especially for opaque or thick materials, where light penetration and energy deposition depth are significantly reduced, making photocuring difficult to apply to colored systems. With increasing demands for energy conservation and emission reduction, electron beam curing, as a new type of green curing technology with fast curing speed, low energy consumption, and no VOC emissions, has found wide application in industries such as printing, packaging, electronics, and automotive manufacturing.

[0003] High water consumption, high energy consumption, and high pollution have always been key issues restricting the development of the textile industry. Therefore, a low-energy and low-water-consumption green dyeing technology for textiles is urgently needed. Electron beam, as a short-process, low-energy curing technology, has seen limited application in textile coloring. Due to the flexible and porous nature of textiles, it is necessary to maintain a soft hand feel and breathability while coloring. However, current electron beam curing colorants do not consider hand feel and breathability, resulting in a stiff hand feel and poor breathability. Furthermore, dyeing fibers involves adsorption, diffusion, and fixation; however, in electron beam curing, the short dyeing process leads to low dye utilization and low color depth. Summary of the Invention

[0004] [Technical Issues]

[0005] Traditional thermosetting coloring technology for textiles is time-consuming and energy-intensive, failing to meet the requirements of low-carbon production. Photocuring coloring technology is limited by the light's penetrability, making it difficult to cure colored systems. Existing electron beam curing colorants result in fabrics that are stiff to the touch, have poor breathability, and have low dye utilization, leading to shallow color depth.

[0086] Table 1 Properties of Electron Beam Cured Colored Fabrics

[0087]

[0088] As can be seen from Examples 1 and 6 and Comparative Examples 1 and 2, if the electron beam radiation intensity is too low, the dye curing effect cannot be achieved. Increasing the electron beam radiation intensity can slightly improve the dye grafting rate and K / S value, but it will seriously damage the fabric.

[0089] As can be seen from Example 1 and Comparative Example 3, although electron beam radiation curing is slightly inferior to high temperature curing in terms of K / S value and color fastness, its energy consumption is significantly reduced.

[0090] As can be seen from Example 1 and Comparative Example 4, electron beam curing can solve the problem of difficult curing of colored systems in UV curing systems and is superior to UV curing in all aspects.

[0091] As can be seen from Example 1 and Comparative Example 6, electron beam curing causes small molecule dyes to decompose and cannot complete curing grafting. Using polymers to covalently anchor the dyes can avoid the decomposition problem, thereby improving the grafting rate of the colored particles.

[0092] As can be seen from Example 1 and Comparative Example 7, the use of cationic dyes in combination can significantly improve the dyeing rate and K / S value. The anionic groups on the surface of the colored particles attract cationic dyes, thereby improving the color depth.

[0093] As can be seen from Example 1 and Comparative Example 8, compared with commercially available electron beam curing colorants, the colorant of this invention has significantly improved hand feel and breathability retention.

[0094] As demonstrated in Example 1 and Comparative Example 9, the use of silane helps to increase the grafting rate and significantly increases the hand feel and breathability retention of the treated fabric.

[0095] As can be seen from Example 1 and Comparative Example 9, preparing the core material into a nano-dispersion can significantly improve the dyeing rate of the fabric, and the hand feel and breathability retention of the treated fabric are also significantly increased.

[0096] The embodiments provided above are not intended to limit the scope of the invention, nor are the described steps intended to limit the order of execution. Any obvious modifications made to the invention by those skilled in the art based on existing common knowledge also fall within the scope of protection defined by the claims.
