specific Embodiment approach 1
[0026] Specific implementation mode one: combine figure 1 with figure 2 To illustrate this embodiment, the specific steps of a method for preparing a tubular fabric with radial elastic shrinkage described in this embodiment are as follows:
[0027] Step 1. The preparation process of warp yarn: select fine denier 75-200D aramid fiber, 100-300D PBO fiber or mixed fiber yarn of aramid fiber and PBO as warp yarn;
[0028] Step 2, the preparation process of the weft yarn: select the composite yarn of aramid filament or PBO filament coated spandex elastic yarn as the weft yarn;
[0029] Step 3. Directly wind the weft yarn into a yarn suitable for the size of the shuttle of the shuttle loom;
[0030] Step 4, determination of the public reed number: determine the public reed number according to the warp density and weft shrinkage parameters, and the selection range of the public reed number is No. 8 to No. 14;
[0031] Step five, weaving process: the specific weaving steps are:

specific Embodiment approach 2
[0037] Specific implementation mode two: combination figure 1 with figure 2To illustrate this embodiment, in step 2 of this embodiment, the warp is twisted: the twist is 100-300 twists / m. In this embodiment, twisting the warp filament multifilament can improve the manufacturing performance of the warp yarn, so that the monofilaments in the fiber bundle will not become loose or slipped after being intertwined or entangled with each other, and the fibers can be avoided during the weaving process. The fluffing phenomenon occurs due to the friction of the reed, and the appearance characteristics such as the best gloss and hand feeling are obtained; the strength and wear resistance of the elastic fabric are determined by the outer fiber, and the most critical parameter is the choice of twist, and the low twist is the flexibility of the yarn Good resistance, but it will lead to deterioration of coating performance, poor strength and wear resistance, increase the twist, the yarn wi...
specific Embodiment approach 3
[0038] Specific implementation mode three: combination figure 1 with figure 2 This embodiment will be described. In this embodiment, the weaving form of the woven fabric is plain weave. The organizational form set up in this way is simple, easy to process, and easy to promote. Other method steps are the same as those in the first or second embodiment.
