Test examples
Test (1), anti-wrinkle performance test: the fabrics prepared in examples 1 to 5 and comparative examples 1 to 3 were respectively designated as fabrics 1 to 8, and the fabrics 1 to 8 were subjected to anti-wrinkle performance tests according to GB/T3819-1997 method for measuring recovery angle of crease recovery of textile fabrics and GB/T13769-2009 method for testing flatness of appearance of washed textile fabrics, wrinkle recovery angles after washing with water and 50 times of home washing, and flatness of appearance after washing with home for 1 time and 50 times, and the test results are shown in tables 1 and 2:
TABLE 1
TABLE 2
As shown by the test results in tables 1 and 2, the anti-wrinkle color-retaining fabric provided by the invention has excellent anti-wrinkle performance and still has good anti-wrinkle performance after being washed for many times. As can be seen from the fabrics 1-5, as the content of the crease-resistant color-preserving finishing agent in the finishing liquid is increased, the crease recovery angle of the fabrics is increased, but when the content of the crease-resistant color-preserving finishing agent is excessive, the crease recovery angle of the fabrics is gradually increased, which indicates that the loads of the fabrics on the crease-resistant color-preserving finishing agent are saturated; as can be seen from the fabric 6, the fabric 7 and the fabric 2, the copolymer of maleic acid, 2-dimethylolpropionic acid and citric acid plays a main role in the crease resistance of the fabric, and has little relation with hydroxybenzotriazole, mercapto-modified nano titanium dioxide and 1, 6-hexanedithiol; as can be seen from the fabric 8 and the fabric 2, the crease resistance of the fabric finished by the crease-resistant color-retaining finishing agent is greatly improved.
Test (2), breaking strength retention test: the fabrics prepared in examples 1-5 and comparative examples 1-3 were respectively designated as fabrics 1-8, and the fabrics 8 were used as reference fabrics according to GB/T3923.1-2013 "first part of textile fabric tensile Properties": determination of breaking Strength and elongation at break (bar sample method) determination of breaking Strength retention of fabrics after 50 times of washing without water and household washing, test results are shown in Table 3:
TABLE 3 Table 3
As shown by the test results in Table 3, the crease-resistant color-retaining fabric has better tensile breaking strength, and as the content of the crease-resistant color-retaining finishing agent in the finishing liquid is increased, the breaking strength retention rate of the fabric is gradually reduced, because the hydroxyl groups on cellulose of a cotton fiber basic unit react with the carboxyl groups in the crease-resistant color-retaining finishing agent to form crosslinking, the relative slippage among molecules of the fabric is difficult to generate along with the increase of the crosslinking degree, the flexibility is reduced, and the breaking strength retention rate of the fabric is reduced; as can be seen from the fabric 7 and the fabric 2, the reduction of the mercapto content in the crease-resistant color retention finishing agent greatly reduces the breaking strength retention rate of the fabric, because the fabric can be mutually converted with disulfide bonds when mercapto is contained in the fabric, the strength of the fabric is ensured, and the flexibility is simultaneously considered, so that the breaking strength retention rate of the fabric 2 is higher than that of the fabric 7.
Test (3), color retention performance test: the fabrics prepared in examples 1-5 and comparative examples 1-3 were respectively designated as fabrics 1-8, whiteness of the fabrics 1-8 was measured according to GB/T17444-2008 "method for whiteness colorimetric test of textile fibers", then the fabrics 1-8 were placed under an ultraviolet lamp and irradiated for 24 hours, the fabrics 1-8 were measured after standing for 2 hours, and the whiteness of the fabrics 1-8 after ultraviolet irradiation was measured, and the test results were shown in Table 4:
TABLE 4 Table 4
As can be seen from the test results of Table 4, the crease-resistant color-retaining fabric has a good color-retaining effect, and as can be seen from the fabrics 1 to 5, the whiteness of the fabric is slightly increased along with the increase of the content of the mercapto-modified nano titanium dioxide in the crease-resistant color-retaining finishing agent in the finishing liquid, because the titanium dioxide is a whitening agent, and the whiteness of the fabric can be slightly increased when the titanium dioxide is added into the fabric; as can be seen from the fabrics 6 and 2, after 24 hours of ultraviolet irradiation, the whiteness of the fabric without the hydroxybenzotriazole and the mercapto-modified nano titanium dioxide is greatly reduced, because the hydroxybenzotriazole and the nano titanium dioxide are both ultraviolet absorbers, and the hydroxybenzotriazole and the nano titanium dioxide are compounded in the fabric to generate a synergistic effect, so that the fabric has better ultraviolet resistance, and the whiteness of the fabric is less reduced.
Test (4), ultraviolet protection performance test: the fabrics prepared in examples 1 to 5 and comparative examples 1 to 3 were respectively designated as fabrics 1 to 8, and the UPF values of the fabrics 1 to 8 were measured according to GB/T18830-2009 evaluation of ultraviolet resistance of textiles, and the measurement results are shown in Table 5:
TABLE 5
| Fabric 1 | Fabric 2 | Fabric 3 | Two-sided noodle 4 | Fabric 5 | Fabric 6 | Fabric 7 | Fabric 8 | |
| UPF value | 66.5 | 67.3 | 65.8 | 83.3 | 83.8 | 7.3 | 67.0 | 6.2 |
As can be seen from the test results in Table 5, the anti-wrinkle color-retaining fabric has good anti-ultraviolet performance; as can be seen from the fabrics 1-6, the anti-ultraviolet performance of the fabric is better along with the increase of the content of the hydroxybenzotriazole and the mercapto-modified nano titanium dioxide in the anti-wrinkle color-retaining finishing agent in the finishing liquid, because the hydroxybenzotriazole and the nano titanium dioxide are both ultraviolet absorbers and can effectively absorb ultraviolet rays, and the nano titanium dioxide not only serves as the ultraviolet absorbers, but also has a certain refraction effect on the ultraviolet rays, and the synergistic effect can be generated when the hydroxybenzotriazole and the mercapto-modified nano titanium dioxide are compounded in the fabric, so that the fabric has better ultraviolet resistance.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
