As can be seen from the test data in table 1, in examples 1 to 2 of the present invention, the fabric of weft-knitted yoga pants is knitted by using a weft-knitted sandwich structure, and the fabric of weft-knitted yoga pants is woven by selecting yarns and yarn densities, wherein the high-elastic semi-gloss nylon DTY yarns or high-elastic matte nylon DTY yarns in the 2 nd, 3 rd, 4 th, 5 th, 7 th, 8 th, 9 th and 10 th paths have a density of (15-30) D/(16-72) F, the spandex yarns in the 2 nd, 3 th, 4 th, 5 th, 7 th, 8 th, 9 th and 10 th paths have a density of (15-30) D, the high-elastic semi-gloss nylon DTY yarns or high-elastic matte nylon DTY yarns in the 1 st and 6 th paths have a density of (8-20) D/(5-24) F; the light transmittance of the weft-knitted yoga trousers fabric prepared in the embodiment 1-2 is 0%, and meanwhile, the weft-knitted yoga trousers fabric is light and thin in gram weight, soft in hand feeling and good in moisture absorption and breathability; the stability, the pull-open degree and the recovery performance are better. Compared with the weft-knitted yoga trousers fabric of example 1, the light transmittance of the commercial yoga trousers fabric of comparative example 1 is 0.8%, and the light transmittance of the commercial yoga trousers fabric of comparative example 2 is 0.5%. Compared with the weft-knitted yoga trousers fabrics prepared in the examples 1 and 2, the commercial yoga trousers fabrics in the examples 1 and 2 have the advantages that although the difference between the pull-open degree and the recovery performance is not large, and the pull-open degree and the recovery performance are higher than the requirements of the national textile industry standard, wherein the pull-open degree weft direction is larger than 100%, the pull-open degree warp direction is larger than 90%, and the warp direction and weft direction recovery rates are larger than 90%, the light transmittance of the weft-knitted yoga trousers fabrics in the examples 1 and 2 is far lower than that of the commercial yoga trousers fabrics in the comparative examples 1 and 2 with heavier gram weight under the condition of lighter and lighter gram weight.
The fabric is woven by using a weft-knitted sandwich structure, the density of the high-elastic semi-gloss nylon DTY yarn or the high-elastic matte nylon DTY yarn in the 2 nd, 3 th, 4 th, 5 th, 7 th, 8 th, 9 th and 10 th paths is (15-30) D/(16-72) F, and the fabric is light and thin in gram weight, soft in hand feeling and good in moisture absorption and breathability; the density of spandex yarns in the 2 nd, 3 rd, 4 th, 5 th, 7 th, 8 th, 9 th and 10 th paths is (15-30) D, so that the stability, the openness and the recoverability of the fabric are ensured; the 1 st path and the 6 th path are connected by high-elastic semi-gloss nylon DTY yarns or high-elastic matte nylon DTY yarns with the density of (8-20) D/(5-24) F, so that the anti-permeability performance is very good; according to the invention, the yarn feeding amount of the yarn is selected, so that the tension of the weft-knitted yoga trousers fabric is good, and yarn hooking and pilling are not easy to occur; the temperature setting of the pre-sizing and the specification setting of the pre-sizing under-dyeing machine in the dyeing and finishing process of the fabric enable the fabric specification to be stable, and meanwhile chicken feet marks are prevented from being generated in the dyeing process of the fabric; and after the sizing, a silicon-containing hydrophilic soft oil auxiliary agent is added, so that the hand feeling is super soft, and the touch feeling is comfortable.
The present invention has been further described with reference to specific embodiments, but it should be understood that the detailed description should not be construed as limiting the spirit and scope of the present invention, and various modifications made to the above-described embodiments by those of ordinary skill in the art after reading this specification are within the scope of the present invention.
