The raised knitted fabric comprises a cloth body, wherein the cloth body has a Roman cloth structure, and the weave structure of the cloth body is shown in figure 1. The Roman cloth belongs to weft knitting fabric, four paths are circulated, and the Roman cloth is woven by a double-faced circular knitting machine. The fabric comprises the following 4 loops per cycle: one path of viscose tencel blended yarn and other paths of different yarns.

From the aspect of yarn structure composition collocation, the material and the structure basis of surface fabric are done well in this application, have also made preparation for the subsequent handling when promoting the surface fabric performance. The viscose tencel blended yarn is selected and used, and the yarn is formed by blending viscose fibers and tencel fibers. The viscose fiber and the tencel fiber are both regenerated cellulose fiber; alkalizing plant cellulose to obtain alkali cellulose, reacting with carbon disulfide to obtain cellulose xanthate, dissolving in dilute alkali solution to obtain viscous solution called viscose, and wet spinning and treating to obtain viscose fiber. Tencel (Tencel) is a solvent-based cellulose fiber, is a trademark name of LYOCELL fiber produced by Acocdis corporation of UK, and is registered in China as "Tencel"; the wood is made into wood pulp, and the wood pulp is dissolved in an ammonium oxide solvent for direct spinning by adopting a (NMMO) spinning process.

In the viscose tencel blended yarn, viscose fibers have the characteristic of soft hand feeling, and the texture and the luster of the fabric can be properly improved after the viscose tencel blended yarn is blended with tencel. The specification of the viscose tencel blended yarn can be 32S/1-40S/1; the blending ratio of the viscose and the tencel is generally 60-80%: 20-40%, preferably 70%: 30 percent. In some embodiments of the present application, the viscose tencel blended yarn is introduced at lane 1.

In the specific embodiment of the application, the other different yarns comprise one viscose polyester blended yarn and/or one nylon spandex-covered machine-covering yarn, the viscose polyester blended yarn can be introduced from the 2 nd path, and the machine-covering yarn is generally introduced from the 3 rd path and the 4 th path. The viscose polyester blended yarn is obtained by blending viscose fibers and polyester fibers, wherein the polyester fibers are polyester fibers generally. Some embodiments of this application accessible viscose fiber and polyester fiber can dye the double-colored characteristics in cover, give the double-colored effect of surface fabric. Specifically, the specification of the viscose polyester blended yarn can be 50S/1; the blending ratio of the viscose to the polyester can be 50-90%: 10-50%, preferably 50%: 50 percent.

The structure of the covered yarn of the chinlon covered spandex machine in the embodiments of the application is shown in fig. 2, and fig. 2 is a schematic structural view of one path of covering yarn in some embodiments of the application.
