3. The random body shaping fabric of claim 1, wherein the spandex is composed of a blend of PU 70D and PU 30D in a mass ratio of 1:0.5-0.8.
4. The stretch fabric of claim 1, wherein the filaments are PA690D/12FD FDY.
5. The random access body shaping fabric of claim 1, wherein the method for preparing the ultra-fine denier polyamide fiber comprises the steps of:
(1) The method comprises the steps of (1) taking a mixture of polyamide 6 and bamboo fibers as an island component and water-soluble acrylic resin as a sea component, mixing the island component, the sea component and magnesium stearate, and stirring to obtain a material A;
(2) The material A is melted and stirred by a single-screw spinning machine and enters a sea-island type spinning assembly, a silk bundle is formed by extruding through a distributing plate and a spinneret plate, and the obtained silk bundle is drawn by three drawing rollers to obtain a material B;
(3) And (3) spinning the material B in an oil bath, curling by a curling machine, drying, and cutting off to obtain the superfine denier polyamide fiber.
6. The fabric for shaping body according to claim 5, wherein the mass ratio of the polyamide 6 to the bamboo fiber in the step (1) is 1:0.8-1.2, the mass ratio of the island component, the sea component and the magnesium stearate is 1:1-2:0.005-0.008, the stirring speed is 80-90rpm, and the stirring time is 30-50min.
7. The free-cutting body-shaping fabric of claim 5, wherein the temperature of the single screw spinning machine in step (2) is 100-150 ℃, and the draft ratio of the three draft rollers is 1:0.8-1.5:2-3.
8. The fabric for shaping body according to claim 5, wherein the temperature of the drying in the step (3) is 90-110 ℃, the length of the ultra-fine denier polyamide fiber is 100-110mm, and the fineness is 9-10dtex.
9. A method for preparing the random-cutting body-shaping fabric as claimed in any one of claims 1 to 8, which is characterized by comprising the following steps:
s1, bonding and intersecting filaments and polyester to form a continuous spindle thread structure 1;
s2, intersecting the superfine denier polyamide fiber with spandex to form a continuous spindle thread structure 2;
s3, continuously intersecting the spindle thread structure 1 and the spindle thread structure 2 for spinning, and obtaining the random body-shaping fabric.
10. The method of claim 9, wherein the filaments and polyester fibers in step S1 are bonded and crossed by hot melt at a ratio of 1:95-105 to form a continuous spindle filament structure 1; the ultra fine denier polyamide fiber in step S2 is cross-formed into a continuous spindle filament arrangement 2 by heat-fusing with spandex at a ratio of 1:45-55.
