And (3) performance testing:
examples 1-6 and comparative example 1 are artificial turf of the same specification without weaving other conventional fibers. Laying elastic pads with the same specification on the bottom of the lawn, wherein the elastic pads are respectively filled with the same weight (about 30 kg/m) without filling2) The quartz sand of (1) was tested for shock absorption, vertical deformation, and ball rolling performance before abrasion, after abrasion of Lisport XL at 3000 revolutions, and after abrasion of Lisport XL at 6000 revolutions, respectively, according to the requirements of FIFA handbook 2015 edition. The results are as follows:
table 1: lawn performance test results of non-mixed weaving other fibers
As can be seen from the performance test results, the high-elasticity artificial lawn provided by the invention has the advantages that due to the special spiral structure, the uprightness performance of the lawn after being worn is obviously superior to that of the common artificial lawn no matter the lawn is filled with quartz sand or is not filled with the quartz sand, the shock absorption and vertical deformation performance of the artificial lawn are also obviously superior to that of the common artificial lawn, and the spiral structure has a certain shock absorption effect. After being worn, the common artificial turf is seriously lodged and cannot keep an upright state, and a certain blocking effect is not provided in the rolling process of the ball, so that the rolling distance of the ball is obviously longer than that of the embodiment of the invention; meanwhile, various performances of the high-elasticity spiral artificial turf obtained by various different heat treatment modes are basically equivalent, and various performances of the spiral artificial turf combined by various different section shapes are basically equivalent.
Examples 7, 8, 9 and 2 are artificial turf of the same specification, and the curved silks are mixed, but the total DTEX of the grass silks in example 8 is lower than that in examples 7 and 2, the grass silks in example 9 are mixed in rows, and the amount of the grass silks is lower than that in comparative example 2. The elastic cushion with the same specification is paved at the bottom of the lawn, the lawn is not filled with any filler, and the shock absorption, vertical deformation and ball rolling performance before abrasion and after 3000 and 6000 revolutions of Lisport XL abrasion are respectively tested according to the requirements of FIFA manual 2015 edition. The results are as follows:
table 2: test result of mixed-woven curved-filament lawn performance
From the above performance test results, it can be seen that the high-elasticity artificial turf of the present invention has a small difference in performance from the ordinary non-filled turf before abrasion under the same condition of mixed weaving of the curved yarn, but has a significant difference in shock absorption and vertical deformation performance after abrasion, which well demonstrates that the shock absorption effect of the helical artificial turf fiber of the present invention is further improved under the comprehensive action of the curved yarn, and the various performances of examples 8 and 9 are still good economical due to the ordinary artificial turf under the condition of reducing the amount of the grass yarn.
Examples 10 to 12 and comparative example 1 were the same size lawn, and other conventional lawn fibers were mixed and woven, and the same size elastic pad was laid on the bottom of the lawn, and the same weight (about 20 kg/m) was filled without filling (not filled), respectively2) The quartz sand of (1) was tested for shock absorption, vertical deformation, and ball rolling performance before abrasion, and after 3000 and 6000 revolutions of Lisport XL abrasion, respectively, according to the requirements of the FIFA manual 2015 edition. The results are as follows:
table 3: test results of mixed conventional fiber lawn
From the above performance test results, it can be seen that the high elasticity artificial turf of the present invention, when mixed with other conventional fibers, is equivalent to replacing the spiral fiber of the present invention with a part of conventional fibers, and the movement performance of the artificial turf is still better than that of the conventional artificial turf.
