Comparative example 5:
the application comparative example 5 provides a preparation method of a suede material, which comprises the following steps:
s1, preparing the suede material
Respectively extruding 100 parts of PET resin slices and 40 parts of COPET water-soluble resin slices by two different screws in parts by mass, and drafting by a distribution box to obtain the figured fiber;
s2, cutting the figured fiber into short fibers to prepare non-woven fabrics, and then sequentially performing the working procedures of ironing the non-woven fabrics → impregnating polyurethane resin → solidifying → washing with water → reducing and opening fibers → raising → dyeing → post-processing on the non-woven fabrics to obtain the suede material.
The materials prepared in examples 1 to 10 and comparative examples 1 to 5 were subjected to a luminescence property test and a luminescence property test after aging. The method specifically comprises the steps of cutting a 300 x 300mm sample, insolating for 1h at noon in summer, testing the brightness degree and the luminous uniformity of a normal sample and a worn sample under a darkroom condition, carrying out a wear test with reference to GB/T21196.2-4, wherein the load is 1600g, the wear frequency is 10000 times, and the test result is shown in table 1.
Table 1: results of Performance test of the materials prepared in examples 1 to 10 and comparative examples 1 to 5
As can be seen from table 1, the noctilucent suede prepared by the method of the present application has long-lasting effect and still has a certain noctilucence after being worn and used; the test results of the comparative example 1 and the comparative example 1 show that the luminous brightness and the luminous uniformity of the noctilucent powder hyperbranched treated by the amino silane coupling agent are obviously superior to those of the non-amino silane coupling agent, which is probably because the amino silane coupling agent is attached to the surface of the sea-phase PET fiber and the surface of the COPET water-soluble island-phase fiber to form an alkaline interface region which can promote the hydrolysis of the COPET resin, so that the COPET fiber can be relatively easily eluted from the alkaline interface in the alkali weight reduction process of the non-woven fabric, and the PET fiber containing the hyperbranched noctilucent powder is exposed, and therefore, the noctilucent suede material prepared by the noctilucent powder hyperbranched treated by the amino silane coupling agent has better luminous intensity and better luminous uniformity.
It can be seen from the data of examples 1-2 that the luminous intensity and the luminous uniformity of the obtained noctilucent suede material are both better, but due to the slightly different schemes, the overall luminous performance of example 1 is better than that of example 2, mainly because the silane coupling agent is increased in a certain range, the hyperbranched on the surface of the noctilucent powder is more sufficient, and the dispersion in the PET fiber is more uniform, so that example 1 is better than example 2; the overall luminescence of example 1 is better than that of example 3, which is probably because the smaller the particle size of the luminescent powder, the larger the surface area under the same weight, the larger the internal luminescence area of the modified PET fiber, and therefore, example 1 is the same as example 3; the luminescence of example 1 was better than that of example 4 in the whole, mainly because the amount of the luminescence component added in example 1 was higher than that in example 4. Comparing the data of the example 1 and the comparative example 3, the noctilucent powder which is not subjected to amino silane coupling treatment is directly added into the PET fibers, the suede material basically has no noctilucent property, and the noctilucent powder is basically not effectively dispersed in the PET fibers; comparing the data of example 1 with the data of comparative example 4, the same aminosilane coupling agent and the same addition amount are adopted, except that the hyperbranched luminous powder is added into the comparative example 4 in a post-treatment mode after the suede is made, the luminous suede has certain noctilucence both in an initial state and after lasting for 10 hours, but the difference is much larger than that of example 1, and the material of the comparative example 4 has no noctilucence basically after being worn for a certain number of times, so that the luminescence of the material after being used cannot be ensured; comparative example 5 the suede material did not have luminescence because the noctilucent powder was not added in any way during the entire process.
