experiment example 1

[0044] Experimental example 1: Basic formula evaluation of sprayable hygroscopic ink

[0045] The compositions of the sprayable hygroscopic inks of Examples 1 to 4 are shown in Table 1. In each embodiment, the pigment is a disperse dye, the hygroscopic agent is polyether ester SRT (trade name, provided by Sino-Japanese Synthetic Chemical Company), the dispersant is Solsperse W100 (trade name, provided by Lubrizol company), and the humectant is glycerin and / or Or triethylene glycol (provided by Emperor One Chemical Company), the surfactant is Surfynol 465 (trade name, provided by Air Product Company) and BYK348 (trade name, provided by CABOT Company), and the acid-base regulator is triethanolamine (provided by Emperor One Chemical Company) Provided), the thickener is polyvinylpyrrolidone (provided by Teiichi Chemical Co., Ltd.).

[0050] Experimental Example 2: Stability Evaluation of Sprayable Hygroscopic Ink

[0051] Disperse dyes of different colors are used as colorants to prepare the sprayable hygroscopic ink of embodiment 5 to embodiment 7, wherein the colorant of embodiment 5 is Cyan disperse dyes, and the colorant of embodiment 6 is Magenta disperse dyes, And the colorant of embodiment 7 is Yellow disperse dye. In addition, the hygroscopic agent of each Example is polyether ester SRT. The sprayable hygroscopic inks of Examples 5 to 7 were subjected to accelerated aging experiments to test the stability of the sprayable hygroscopic inks. The test method is to store the sprayable hygroscopic ink at 50°C for 7 days, and measure the changes of ink viscosity, surface tension, pH value and dispersoid particle size (D90) before and after the experiment, as shown in Table 2.

[0055] Experimental example 3: Evaluation of color difference uniformity after spraying and dyeing fabric with sprayable hygroscopic ink

[0056] The sprayable hygroscopic inks of Examples 5 to 7 were sprayed on non-elastic polyester knitted fabrics and elastic polyester knitted fabrics, and the color difference CMCΔE after spraying was measured with a data color spectrometer, as shown in Table 3.

[0058] Color difference CMCΔE Example 5 Example 6 Example 7 Non-elastic polyester knitted fabric 0.25 0.21 0.25 Elastic polyester knitted fabric 0.21 0.27 0.32

[0059] It can be seen from Table 3 that the color difference CMCΔE after the sprayable hygroscopic inks of Examples 5 to 7 are sprayed on fabrics are all less than 0.6. It can be seen that the sprayable hygroscopic ink can be evenly sprayed onto the fabric through the digital printing process, so that the color difference of each block of the fabric is very small (t...

Abstract

The invention relates to sprayable moisture absorption type ink for a digital printing process of fabric and moisture absorption fabric. The sprayable moisture absorption type ink includes 3.0-6.0 parts by weight of a pigment, 0.5-2.0 parts by weight of a moisture absorbent, 0.5-1.0 part by weight of a surfactant and the balance of a solvent, wherein the pH value of the moisture absorbent at 25 DEG C is 6.0-8.5, and the particle size (D90) of the sprayable moisture absorption type ink is 180-220 nm. The sprayable moisture absorption type ink disclosed by the invention is sprayed on the fabric through the digital printing process, so that the moisture absorption fabric with attractive appearance and functionality can be formed at the same time.

Description

technical field [0001] The present disclosure relates to a sprayable hygroscopic ink, and in particular to a sprayable hygroscopic ink for digital printing process of fabrics, and a hygroscopic fabric sprayed with said ink. Background technique [0002] In recent years, people's awareness of family leisure and health has gradually increased, so consumers' demand for functional fabrics has also increased. A functional fabric popular among consumers is hygroscopic fabric, which can not only quickly absorb sweat, but also has a breathable effect, so as to keep the body dry. Therefore, how to perform moisture absorption treatment on fabrics is an important post-finishing technology in recent years. development projects. [0003] However, the traditional treatment of absorbent cloth is often achieved by the secondary processing method of dyeing first and then finishing. Due to the limitation of the secondary processing method, the color of the fabric is easily affected by the f...
