5. Index testing
5.1 Depasting Rate test
The paste removal rate is one of important indexes for representing the hand feeling of printed fabricsThe paste removal rate is not only related to the printing process, but also depends on the characteristics of the paste, the printed fabric with high paste removal rate is soft to touch, and the paste removal rate is expressed as (m) =2-m3)/(m2-m1) Calculating the rate of paste removal by 100%, wherein m1、m2、m3The dry weight/g of the fabric before printing, after printing and after soaping are respectively.
5.2 apparent color yield test
Using colorimeters at D65Respectively testing the color depth (K/S) of the front surface of the printed fabric under the conditions of a light source and a standard of 10 DEGIs just) The larger the K/S value, the deeper the apparent color yield.
By the above tests, the paste removal rate of the samples prepared in examples 1-4 is shown in FIG. 1, and the color yield of the samples prepared in examples 1-4 is shown in FIG. 2.
As can be seen from figure 1, after the desizing agents of the examples 1 to 4 are added, the paste removing rate of the sodium carboxymethyl cellulose reaches over 90 percent, which is obviously higher than 80 percent of the paste removing rate of the comparative example, and the prepared fabric has soft hand feeling. FIG. 2 shows that the fabric color yield of the examples can be improved by 5% -10% compared with the comparative examples, which shows that the desizing agent has better active group shielding performance on the paste, and the effective concentration of the dye is increased under the effect of the desizing agent, so that the dye uptake is improved.
