An experimental instrument: round-track pilling machine (model HT-Y235 from Shanghai billow Automation Equipment, Inc.).
The experimental method comprises the following steps: according to the standard regulation of GB/T4802.1-2008 'textile fabric pilling test', an experimental sample 1 firstly fuzzes with a nylon brush and then rubs and pilling with a fabric abrasive material along a circular motion track under 490cN pressure, and the fuzzing is carried out 50 times and the pilling is carried out 50 times;
and then visually describing and evaluating the pilling performance of the experimental sample 1 under the specified illumination condition according to the national standard GB/T4802.1-2008 'pilling test of textile fabrics'. The rating was from 1 to 5, with grade 1 being the worst (most pilling) and grade 5 being the best (no pilling), and half grades were allowed, and 5 test specimens 1 were averaged after each rating. Although the general rating grade in the national standard is the minimum precision of 0.5 grade, 0.1 is taken as the minimum precision in the actual rating in order to better compare the difference of the fuzzing and pilling performances between fabrics.
The experimental samples 2 to 18 and the comparative samples 1 to 6 were subjected to the anti-pilling property experimental test according to the above experimental method.
The experimental results are as follows: the results of the pilling resistance test of the test samples 1 to 18 and the comparative samples 1 to 6 are shown in Table 3.
Experiment two: experimental sample of abrasion resistance: the terylene DTY of examples 1-18 and comparative examples 1-6 were adopted and woven by a weaving method to obtain circular terylene face fabric with a diameter of 130mm, the circular terylene face fabrics obtained in examples 1-18 were respectively named as experimental samples 1-18, the circular terylene face fabrics obtained in comparative examples 1-6 were respectively named as comparative samples 1-6, and 5 of the experimental samples 1-18 and the comparative samples 1-6 were provided.
An experimental instrument: martindale abrasion resistant instrument (the manufacturer is Wuhan national instruments Co., Ltd., model No. YG 401E).
The experimental method comprises the following steps: reference is made to GB/T21196.3-2007 "determination of abrasion resistance of textile Martindale fabrics part 3: measurement of Mass loss test method for testing a test sample, for example, the test sample 1 is weighed m before the test1Then, a Martindale abrasion tester is adopted to carry out abrasion resistance experiment on the experimental sample 1, after 500 times of abrasion, the weight m of the experimental sample is weighed2And the wear rate of the experimental sample 1 was calculated as (m)1-m2)/m1X 100%, the wear rates of 5 test samples 1 were calculated, respectively, and the average value was taken as the final wear rate of test sample 1.
The wear resistance tests were carried out on the experimental samples 2 to 18 and the comparative samples 1 to 6 according to the above-mentioned experimental methods.
The experimental results are as follows: the results of the abrasion resistance tests of the test samples 1 to 18 and the comparative samples 1 to 6 are shown in Table 3.
TABLE 3 results of the experiments of the experimental samples 1 to 18 and the comparative samples 1 to 6
As can be seen from the experimental data in Table 3, the experimental samples 1-18 had a pilling resistance rating of 4.0-4.8 and a wear rate of 0.12-0.25%, and the comparative samples 1-6 had a pilling resistance rating of 2.3-3.7 and a wear rate of 0.32-0.54%; the experimental samples 1-18 have better pilling resistance and lower wear rate than the comparative samples 1-6, which shows that the experimental samples 1-18 have good pilling resistance and high wear resistance.
Comparing the experimental sample 1 with the comparative samples 1-3, it can be seen that after the anti-pilling agent wheat straw powder and the sodium alginate are added, the pilling condition of the polyester DTY can be reduced, and the wear resistance can be enhanced, probably because the wheat straw powder has a smooth surface and is waxy, and meanwhile, the wheat straw powder contains more silicon dioxide, and the sodium alginate has excellent biocompatibility, and the friction coefficient is reduced by matching the wheat straw powder and the sodium alginate, so that the pilling condition of the polyester DTY is further enhanced; comparing the experimental sample 1 with the comparative samples 3-5 shows that the silicon carbide and the anti-pilling agent are matched to enhance the wear resistance and anti-pilling performance of the polyester DTY.
Comparing the experiment sample 1 with the experiment samples 3-4, the wear-resisting agent oyster shell powder and graphite powder have more metal elements, and the graphite powder and the oyster shell powder have higher hardness and better smoothness, so that the wear resistance of the terylene DTY is further enhanced; comparing the experimental sample 1 with the experimental samples 5-8, the reinforcing agents polyvinyl alcohol and talcum powder have better viscosity and strength, and are matched with the anti-pilling agent and the wear-resisting agent to further enhance the wear resistance and anti-pilling performance of the polyester DTY; comparing the experimental sample 1 with the experimental samples 9-10, it can be known that controlling the melt extrusion temperature and pressure is helpful for improving the pilling performance of the polyester DTY, and can better melt and extrude the raw materials stably, improve the stability, and further enhance the anti-pilling performance; comparing the experiment sample 1 with the experiment samples 11-12, the protease in the finishing agent is matched with the chitosan, so that the wear resistance and the anti-pilling performance of the polyester DTY are improved; amino and hydroxyl in the chitosan can be dehydrated and can form a film on the surface of the polyester DTY under the combined action of protease, so that the mutual occlusion of the polyester DTY is prevented, and the directional friction effect between fibers is reduced, thereby enhancing the wear resistance and the anti-pilling performance of the polyester DTY.
Comparing the experimental sample 12 with the experimental samples 13-14, it can be seen that the surface of the polyester DTY can be effectively wetted by selecting the penetrants sodium surfactin and dioctyl sodium sulfosuccinate, and the penetrants are effectively matched with protease and chitosan to enhance the wear resistance and anti-pilling performance of the polyester DTY; comparing the experimental sample 12 with the experimental samples 15-16, it can be seen that the added mushroom powder contains more tyrosine, and after the mushroom powder is matched with the protease, a layer of protein film is formed on the surface of the polyester DTY, so that the friction coefficient of the surface of the polyester DTY is reduced, the directional friction effect is reduced, and the anti-pilling performance of the polyester DTY is further enhanced; comparing the experimental sample 1 with the experimental samples 17-18, the steps in the experimental process are controlled, the formulas of the polyester DTY raw material and the finishing agent are optimized, and the reinforcing agent is added into the polyester DTY raw material, so that the wear resistance and the anti-pilling performance of the polyester DTY can be greatly enhanced.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
