DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides a fabric with high resilience. The fabric with high resilience is obtained by interweaving an upper fabric and a lower fabric, then hot water retreating and drying. The upper fabric is formed by interweaving a surface weft and a surface warp, and the lower fabric is formed by interweaving an inner weft and an inner warp. When the upper fabric is organized, the inner warp of the lower fabric is lifted and interwoven with the surface weft of the upper fabric, and when the lower fabric is organized, the surface warp of the upper fabric sinks and interweaves with the inner weft of the lower fabric to form a joint connection. The surface weft is composed of two first surface wefts and a second surface weft distributed side by side. The first surface weft is a pure cotton yarn and a water-soluble vinyl fiber that are paralleled and twisted to form a yarn. The inner weft is composed of two first inner wefts and a second inner weft that are arranged side by side. The first inner weft is a combed Cotton blended yarn and water-soluble vinylon fiber are paralleled and twisted into yarn. The second surface weft and the second lining weft are both water-soluble vinylon fibers, and the lining warp and surface warp are both spandex yarns. The cross-section of the water-soluble vinylon fiber is an octagonal star shape. After retreat, the first lining weft and the first surface weft become thinner, and at the same time, the second surface weft and the second lining weft are retreated, so that the remaining warp yarn and weft yarn in the fabric structure have a higher buckling rate, and then through the high elasticity of the spandex yarn, the fabric structure has better fluffiness, drape and elasticity than the common high-rebound fabrics on the market. The cross-sectional shape of the water-soluble vinylon fiber is set to an octagon, so that thicker fibers can be obtained with less raw materials, and further the fabric can obtain more fluffiness space after retreat.

[0038] A processing equipment for fabrics with high resilience, comprising wet spinning equipment, spinning equipment and weaving equipment; the wet spinning equipment consists of a stock liquid tank, a stock liquid output pipe, a metering pump, a pre-filter, a controller with an alarm, a coagulation bath, a fixed plate 4, a wire guide and a winder, wherein the fixed plate 4 is fixedly connected to the inner wall of the coagulation bath and close to one end of the metering pump; a main feed pipe 1 is fixedly connected to the output end of the metering pump, a diverter 2 is fixedly connected to the end of the main feed pipe 1 away from the metering pump, a group of inlets and four groups of outlets are arranged on the diverter 2, the main feed pipe 1 is fixedly connected to the inlet of the diverter 2, and the four groups of outlets of the diverter 2 are respectively fixedly connected to the branch feed pipes 3, a spinneret device for spraying a filament bundle is arranged on the fixed plate 4, the diverter 2 and the main feed pipe 1, and the spinneret device comprises: a filter plate 5, a filter assembly, a pressure detection assembly, a valve assembly, a panel 6 and a spinneret assembly; the pressure detection assembly and the valve assembly are both electrically connected to the controller.

[0039] The filter plate 5 is fixedly connected to the right wall of the fixed plate 4. Four groups of filter cavities 13 are distributed in sequence on the inner wall of the filter plate 5 from front to back. The ends of the four feed pipes 3 away from the diverter 2 sequentially penetrate the side wall of the coagulation bath and the inner wall of the fixed plate 4 and extend into the four groups of filter cavities 13 respectively. The spinning solution enters the four groups of filter cavities 13 after being diverted by the diverter 2.

[0040] The filter assembly is arranged inside the filter cavity 13, and the filter assembly is used to filter impurities in the spinning solution. The filter assembly includes multiple groups of filter frames 16. The inner wall of the end of the filter cavity 13 away from the fixed plate 4 is provided with a mounting step 14. The multiple groups of filter frames 16 are arranged in sequence from left to right on the inner wall of the mounting step 14. The mounting step 14 is threadedly connected to a locking ring 17 on the side of the panel 6. The multiple groups of filter frames 16 are all pressed by the locking ring 17. The inner wall of the filter frame 16 is provided with a filter screen 15. The spinning solution is fully filtered through the multiple groups of filter screens 15 to prevent impurities from affecting the quality of the silk.

[0041] The pressure detection component is arranged between the main feed pipe 1 and the filter plate 5. The pressure detection component is used to detect the feed pressure. The pressure detection component includes a second pressure sensor 18 and four groups of first pressure sensors 8. The second pressure sensor 18 is fixedly connected to the outer wall of the main feed pipe 1. The four groups of first pressure sensors 8 are fixedly connected to the upper wall of the filter plate 5 in sequence from front to back and correspond to the four groups of filter cavities 13 in the upper and lower directions respectively. The lower ends of the second pressure sensor 18 and the four groups of first pressure sensors 8 are both provided with a detection head 12. The detection head 12 of the second pressure sensor 18 penetrates the upper wall of the main feed pipe 1 and extends into the interior of the main feed pipe 1. The four groups of first pressure sensors 8 are fixedly connected to the upper wall of the filter plate 5 in sequence from front to back and correspond to the four groups of filter cavities 13 in the upper and lower directions respectively. The detection heads 12 of the sensors 8 all penetrate the upper wall of the filter plate 5 and extend into the four groups of filter chambers 13 respectively. The second pressure sensor 18 is used to detect the feed pressure, and the first pressure sensor 8 is used to detect the internal pressure of the filter chamber 13. After the raw liquid is diverted by the diverter 2, the sum of the pressures in the four groups of filter chambers 13 should be equal to the feed pressure. When the filter screen 15 is blocked, the pressure in the filter chamber 13 will rise. When it rises to the safety warning value, the controller controls the valve assembly to cut off the corresponding on / off of the filter chamber 13 to avoid the serious blockage of the filter screen 15, which leads to insufficient pressure of the spinneret 10. Insufficient pressure will lead to poor quality of the tow.

[0042] The valve assembly is arranged on the upper wall of the diverter 2. The valve assembly is used to control the flow of the four-component feed pipe 3 according to the detection result of the pressure detection assembly. The valve assembly includes four sets of electrically controlled opening valves 7. The four sets of electrically controlled opening valves 7 are fixedly connected to the upper wall of the diverter 2 in sequence from front to back. The flow rate in the four-component feed pipe 3 is controlled by the four sets of electrically controlled opening valves 7. The four sets of electrically controlled opening valves 7 on the diverter 2 are used to control the feed pressure balance of the four-component feed pipe 3 and to cut off a set of channels blocked by the filter screen 15.

[0043] The panel 6 is fixedly connected to a side of the filter plate 5 away from the fixed plate 4;

[0044] The spinneret assembly is arranged on the side of the panel 6 away from the filter plate 5, and the spinneret assembly is used to spray the raw liquid into the coagulation bath. The spinneret assembly includes a spinneret cap 9, a spinneret hole 10 and a protruding nozzle 11. The spinneret cap 9 is fixedly connected to the side of the panel 6 away from the filter plate 5. The inner wall of the filter plate 5 is provided with a through cavity connecting the spinneret cap 9 and the filter cavity 13. The protruding nozzle 11 is arranged on the side of the spinneret cap 9 away from the panel 6. The outer wall of the protruding nozzle 11 away from the spinneret cap 9 is provided with a cone head. The spinneret hole 10 is arranged on the inner wall of the spinneret cap 9 and the protruding nozzle 11. The spinneret hole 10 makes the through cavity and the coagulation bath pass through the setting of the protruding nozzle 11, so that the surface of the spinneret hole 10 is not easy to accumulate coagulants and will not be blocked. The side view cross-section of the spinneret hole 10 is in the shape of a M. The M-shaped cross-section makes the filament bundle expand to form an octagonal star shape after being sprayed out, and the coarseness of the filament bundle is increased with less raw material, so that there is a larger space between the remaining yarns after de-dimensionalization.

[0045] A method for preparing a fabric with high resilience, the method comprising the following steps:

[0046] S1, take spandex yarn, combed cotton yarn and pure cotton yarn for use;

[0047] S2, take water-soluble vinylon fiber stock solution and send it into the stock solution tank, which is metered by the metering pump and filtered by the pre-filter, and then enters the diverter 2 for diversion, and is sent to the filter plate 5 through the four-component feed pipe 3, filtered by the filter screen 15, and then sprayed out through the spinneret hole 10 on the spinneret 9, and then sprayed into the coagulation bath. After that, vinylon fiber filaments are prepared in the coagulation bath of saturated sodium sulfate aqueous solution in the coagulation bath. When the four groups of first pressure sensors 8 detect that the internal pressure of one group of filter chambers 13 is too high, the controller closes the corresponding electric control opening valve 7, and the alarm on the controller sounds an alarm. When the four groups of first pressure sensors 8 detect that the internal pressure of one group of filter chambers 13 is too low, the controller increases the opening of the corresponding electric control opening valve 7 to increase the internal pressure of the filter chamber 13, so that the pressure in the four groups of filter chambers 13 is consistent;

[0048] S3, doubling and twisting the combed cotton yarn and the pure cotton yarn with the vinylon fiber to form a first inner weft and a first outer weft;

[0049] S4, using spandex yarn as the inner warp and outer warp, two groups of polyvinyl filaments as the second outer weft and the second inner weft, and the first inner weft and the first outer weft prepared in step S3 to weave together using a weaving device and a combined binding method to form a semi-finished fabric interwoven with an upper fabric and a lower fabric, wherein in the combined binding method, when the upper fabric is woven, the inner warp of the lower fabric is lifted up to be interwoven with the outer weft of the upper fabric, and when the lower fabric is woven, the outer warp of the upper fabric is sunken to be interwoven with the inner weft of the lower fabric;
