Performance detection analysis
Test No.)
Test subjects: the color stripe fabrics processed in examples 1 to 11 were used as test samples 1 to 11, and the color stripe fabrics processed in comparative examples 1 to 5 were used as control samples 1 to 5.
The test method comprises the following steps:
1. fastness to water immersion the test standards are determined with reference to the international standard ISO 105-EO 1.
2. Fastness to soaping the test standard is determined with reference to the international standard ISO 105-C10.
TABLE 1
As can be seen by combining examples 1-11, comparative examples 1-5 and commercial products 1-2 with Table 1, the color stripe fabrics corresponding to examples 1-11 were found to have no wrinkles, curling, fading and floating color when examined by light. Comparative examples 1-5 and commercial products 1-2 all had different degrees of surface problems. Meanwhile, the soaping fastness and the water immersion fastness of comparative examples 1-2 and commercial products 1-2 were inferior to those of examples 1-11. The total length of processing for 1 piece of cloth for examples 1-11 was in the range of 1.8-2.4 hours, while the total length of processing for 1 piece of cloth for comparative example 3 was about 4.2 hours and the total length of processing for 1 piece of cloth for commercial products 1-2 was in the range of 3.5-4 hours. Therefore, the soaping-resistant color fastness and the water-immersion-resistant color fastness of the color stripe fabric can be effectively improved by simultaneously shortening the temperature of the whole processing flow through reasonably controlling the presetting and the final setting.
As can be seen from example 1 and examples 8-11 in combination with Table 1, example 1 has a soaping fastness of about grade 2 and a water-soak fastness of about grade 2-3; the colorfastness to water immersion of examples 8-11 were all on the order of 2-3, but the fastness to soaping of examples 8 and 10 was on the order of 3, and the fastness to soaping of examples 9 and 11 was on the order of 3-4. Therefore, the same processing flow is maintained, and the change of the temperature has great influence on the soaping color fastness and the water immersion color fastness of the whole color stripe fabric. It can be seen by combining the details of examples 2-3 and examples 8-10 that the soaping fastness at both the pre-and final-set temperatures above 180 deg.C (i.e. 182 deg.C, 185 deg.C) is inferior to that at both the pre-and final-set temperatures below 180 deg.C. And the slight change of the pre-setting and final-setting temperatures has little influence on the color fastness to water dipping of the color stripe fabric.
As can be seen from example 1, comparative examples 1-2 and comparative examples 4-5 in combination with Table 1, the soaping color fastness and the water immersion color fastness of the color stripe fabric are better when the pre-setting and final-setting temperatures are in the range of 170 ℃ and 185 ℃. When the presetting temperature is higher than 185 ℃ (190 ℃), the color fastness to soaping and the color fastness to water immersion of the color stripe fabric are both greatly reduced; when the presetting temperature is lower than 170 ℃ (only 160 ℃), the color stripe fabric of the comparative example 4 is found to have obvious flooding, fading and slight curling when being checked by a lamp (the fabric surface problem of the color stripe fabric can be seen by naked eyes without carrying out soaping fastness and water-immersion fastness detection). When the final setting temperature is lower than 170 ℃ (only 150 ℃), the color fastness to soaping and the color fastness to water soaking of the color stripe fabric are greatly reduced; when the final setting temperature is higher than 185 ℃ (190 ℃), the color stripe fabric of the comparative example 5 is also found to have obvious flooding, fading and slight curling when being checked by a lamp (the fabric surface problem of the color stripe fabric can be seen by naked eyes without carrying out soaping fastness and water-immersion fastness detection).
According to the example 1 and the comparative example 2, the cloth surface of the color stripe fabric of the comparative example 2 is found to have no wrinkles but has an unobvious curling phenomenon during light inspection, so that the setting temperature in the final setting procedure is not up to the requirement (namely, the final setting temperature is too low) at 150 ℃, and the problem of cloth surface curling cannot be solved.
According to the example 1, the comparative example 1 and the comparative example 3, it can be seen that the cloth cover problem is alleviated by adding the processes (namely, the three steps of adding the falling water washing wool grey cloth, dewatering the blank cloth and finishing the wool grey cloth), but the cloth cover of the color stripe fabric still has slight phenomena of floating color, fading and edge curling during the light inspection, so that the cloth cover problem of the color stripe fabric processed by the mode of adding the processes is still larger than that of the color stripe fabric of the example 1 in the application. In conclusion, the cloth cover problem of the color stripe fabric can be effectively reduced by controlling the presetting, the final setting temperature and the process shortening mode, and the soaping color fastness of the color stripe fabric to disperse dyes is improved.
