Performance testing
Properties of the sublimation-preventing and water-resistant decorative films obtained in examples 1 to 3 and those of commercially available decorative films were measured in the following manner, and the results are shown in Table 1.
(1) And (3) water washability test: the washing was carried out 100 times for 60 minutes each in a 40 ℃ washing machine in accordance with JIS L0217103.
(2) Dry cleaning resistance test: according to GB/T19981.2-2005 part 2 of professional maintenance, dry cleaning and wet cleaning of textiles, fabrics and garments, dry cleaning was performed 15 times using the procedure standard for the dry cleaning and the press performance tests of tetrachloroethylene.
(3) Testing the wet heat aging sublimation resistance: the test environment temperature is 70 ℃, the humidity is 95% or more, and the test is carried out for 30 days.
(4) High-temperature thermal aging sublimation resistance test: baking in a blast oven at 100 ℃ for 7 days.
(5) High-temperature thermal aging sublimation resistance test: and (3) carrying out hot pressing on the anti-sublimation water-fast-washing decorative film product on the textile fabric easy to sublimate by using a flat plate pressing machine under the conditions of temperature of 150 ℃, pressure of 0.4mPa and time of 15 seconds, cooling for 30 minutes, and tearing off the matte PET release film to test according to the test standard.
TABLE 1 Properties of anti-sublimation water-resistant decorative films prepared in examples 1 to 3 and commercial decorative films
As can be seen from the above table, the anti-sublimation water-resistant decorative films prepared in examples 1 to 3 all have soft hand feeling, good dry-cleaning resistance and water-cleaning resistance, and can effectively prevent the sublimation and migration of the color of the textile fabric; however, sublimation color points appear in the commercially available decorative film in a water washing resistance test, a damp-heat aging sublimation resistance test and a high-temperature heat aging sublimation resistance test, which seriously affects the appearance quality of the product and the decorative film effect of the clothes. Therefore, the sublimation-proof water-resistant decorative film has excellent comprehensive performance and good application prospect.
