Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically relating to a device for processing lace needle-punched composite fabrics. Background Technology

[0002] As living standards improve, people have higher requirements for their clothing and appearance. The demand for lace fabric combined with other fabrics is increasing, and the requirements are also getting higher. Because lace fabric is light and transparent, and has an elegant and mysterious artistic effect, combining lace fabric with other fabrics is a fashion trend pursued by women.

[0003] Existing lace composite fabrics all use adhesive lamination technology. The lamination process between lace fabric and base fabric consists of four steps: preparation, dyeing, adhesive heating and lamination, and cooling and curing. The first step is to set the guide rollers of the base material according to the weave pattern and determine the appropriate adhesive ratio. The second step is to turn on the heating device of the oven to heat it. After heating to the accurate temperature, the machine is turned on for dyeing. The dyeing process is not complicated; it only requires applying the dye to the base material that has passed through the anilox rollers and then drying it.

[0004] The third step is double-adhesive lamination, a process automatically produced by a laminating machine, which applies adhesive to the lace fabric and the base fabric while they are still in the adhesive state. The fourth step is cooling, which allows the adhesive to cure and achieve a strong bond between the two. Finally, the finished product is rolled up.

[0005] This composite method involves adhesive bonding. Lace composite fabrics are bonded together using PUR hot melt adhesive, TPU, etc. Adhesive-bonded composite fabrics are not soft and are prone to deformation and wrinkling after washing. In severe cases, they are prone to delamination, which does not meet the requirements of high-end clothing fabrics.

[0006] To overcome the shortcomings of existing technologies, CN201910198243.3 discloses a production process for lace needle-punched composite fabric. The method includes: pretreatment, dyeing, lamination of the face fabric and base fabric, cooling and setting, and post-treatment. The face fabric is made of lace. In the lamination process, the fibers of the face fabric and base fabric are intertwined and bound together through a needle-punching process, and reinforced by needle punching to form a composite fabric. Before the needle punching process, a layer of hot melt adhesive film is laid on the surface of the face fabric. After the needle punching is completed, the hot melt adhesive film is removed, followed by a heating and lamination operation.

[0007] This lace needle-punched composite fabric production process involves introducing hot melt adhesive into the fabric fibers through needles during needle punching. The hot melt adhesive, after being heated and dissolved, bonds the lace fibers and the base fabric fibers together. The simultaneous action of needle punching and adhesive bonding enhances the composite effect. Compared to traditional lace adhesive bonding methods, this method uses less adhesive, resulting in a lower adhesive content in the fabric, a softer feel, and improved wash resistance and anti-shedding properties. However, a hot melt adhesive film is still applied to the surface of the outer fabric before bonding. After needle punching, this film is removed, followed by another heating bonding process. The resulting composite fabric still deforms and loses its shape after washing, failing to meet the performance requirements of high-end clothing for lace needle-punched composite fabrics in terms of deformation resistance, wrinkle resistance, and anti-shedding properties. It is prone to wrinkling, deformation, and pilling, and has poor abrasion resistance. Color stability is also poor; repeated washing will cause it to lose its original high-end, sophisticated texture and luster. At the same time, this production method involves many steps, has a long cycle, high energy consumption, poor water resistance, and does not meet the requirements of environmentally friendly production. Utility Model Content

[0008] The purpose of this invention is to provide a special equipment for processing needle-punched, air-woven, steam-rolled, and press-bonded lace non-adhesive composite fabrics.

[0009] The technical solution adopted by this utility model is as follows:

[0010] A specialized device for processing needle-punched, air-woven, and steam-rolled pressed lace-free composite fabric includes a bidirectional needle punching machine, a high-pressure air-woven machine, and a high-temperature steam rolling ironing machine arranged in sequence. The bidirectional needle punching machine performs bidirectional needle punching to connect the lace fabric and the base fabric in the lace-free composite fabric to obtain a two-material primary bonded composite fabric. The high-pressure air-woven machine air-weaves the two-material primary bonded composite fabric to produce a two-material reinforced air-woven fabric. The high-temperature steam rolling ironing machine continuously steam-rolls and irons the two-material reinforced air-woven fabric to obtain a high-end composite finished fabric.

[0011] Furthermore, the high-pressure air weaving machine includes a high-pressure air chamber, a pneumatic jet roller, a pressure regulating valve, and a high-pressure air source. The pneumatic jet roller has a hollow structure. The high-pressure air source is connected to the axial high-pressure chamber of the pneumatic jet roller through the pressure regulating valve. A high-pressure jet structure is provided on the side wall of the pneumatic jet roller. The high-pressure airflow ejected from the high-pressure jet structure pulses and jets the lace fibers passing through the base fabric, inserting the lace fibers passing through the base fabric into the base fabric from a reverse misalignment, thereby realizing multi-dimensional air weaving between the lace fibers and the base fabric and forming a more robust entangled and cohesive structure.

[0012] Furthermore, the pneumatic jet roller includes an axial high-pressure chamber, a fixed cylinder, and a rotating cylinder. The rotating cylinder is fitted onto the fixed cylinder and can rotate freely relative to the fixed cylinder. An air outlet is provided on the outer wall of the fixed cylinder, and the air outlet is located within the arc segment that contacts the needle-punched composite fabric. A forward jet hole, a vertical jet hole, and a reverse jet hole are provided on the outer circular wall of the rotating cylinder. When the double-material primary bonding composite fabric rotates along the rotating cylinder, the high-pressure gas ejected from the forward jet hole, the vertical jet hole, and the reverse jet hole forces the outer ends of the lace fibers to be implanted into the base fabric in different parts and in different directions, thereby achieving a multi-dimensional and firm entanglement and connection between the lace fibers and the base fabric, and achieving a secondary reinforcement connection through high-pressure air weaving.

[0013] Furthermore, the forward jet holes, vertical jet holes, and reverse jet holes are spaced apart circumferentially and axially.

[0014] Furthermore, the forward jet nozzle, vertical jet nozzle, and reverse jet nozzle are distributed at intervals along the circumferential and axial directions as follows: along the circumferential direction, the air jet of the forward jet nozzle is inclined to the left, the air jet of the vertical jet nozzle is perpendicular to the side of the needle-punched composite fabric, and the air jet of the reverse jet nozzle is inclined to the right; along the axial direction, the air jet of the forward jet nozzle is inclined to the front, the air jet of the vertical jet nozzle is perpendicular to the side of the needle-punched composite fabric, and the air jet of the reverse jet nozzle is inclined to the rear.

[0015] Furthermore, the forward jet hole, vertical jet hole, and reverse jet hole are all pressurized nozzles with a small outlet cross-section and a large inlet cross-section.

[0016] Furthermore, the high-temperature steam rolling ironing machine includes a steam rolling roller, a spray nozzle, and a temperature-adjustable rolling roller. The temperature-adjustable rolling roller is located on one side of the steam rolling roller, and the center distance between the temperature-adjustable rolling roller and the steam rolling roller is adjustable. The double-material reinforced air-woven fabric is located between the temperature-adjustable rolling roller and the steam rolling roller. The spray nozzle is located on the base fabric side of the double-material reinforced air-woven fabric and is located before the double-material reinforced air-woven fabric is subjected to steam rolling ironing. The steam rolling roller includes a hollow fixed roller, a rotating roller, and a fixed roller covering ring. The rotating roller is fitted on the outer circle of the hollow fixed roller, and the fixed roller covering ring is fixed on the outer circle of the rotating roller. Steam injection holes are provided on the outer circle of the hollow fixed roller, and the steam injection holes are distributed on the arc section where the steam rolling roller and the double-material reinforced air-woven fabric are wrapped. Small air injection holes are evenly provided on the outer wall of the rotating roller. The temperature-adjustable rolling roller includes a temperature-adjustable roller and a pressure roller covering ring, and the pressure roller covering ring is fixed on the outer circle of the temperature-adjustable roller.

[0017] Furthermore, the tiny jet nozzle is a pressurized nozzle with a small outlet cross-section and a large inlet cross-section.

[0018] This invention relates to a needle-punched, air-woven, steam-rolled, and press-bonded lace-based composite fabric, comprising a lace fabric and a base fabric. The lace fabric and base fabric are joined by bidirectional needle punching using a bidirectional needle punching machine to obtain a two-material primary-bonded composite fabric. This fabric is then subjected to pulsed reverse air weaving with high-pressure airflow on a high-pressure air loom. During this process, the lace fibers in the lace fabric that have passed through the base fabric are irregularly misaligned and implanted back into the base fabric. Under the pulsating impact of the high-pressure airflow, the lace fibers in the lace fabric, driven by needle punching, are implanted into the base fabric, compressing and shrinking the fibers in the base fabric. The double-reinforced air-woven fabric is obtained through a combination of pure physical needle punching and air weaving. This achieves a pure fiber irregular interweaving and penetration between the lace fabric and the base fabric. The double-reinforced air-woven fabric is then continuously ironed at high temperature by a synchronous high-temperature steam rolling iron to obtain a high-end composite finished fabric with a firm interpenetration and smooth ironing of the two fabrics. No adhesive materials are used in the needle punching, air weaving and high-pressure steam rolling continuous ironing process of the lace fabric and the base fabric. The lace fabric and the base fabric have a purely physical composite weaving and firm connection structure.

[0019] The production method of the needle-punched, air-woven, steam-rolled pressed lace non-adhesive composite fabric includes the following steps:

[0020] S1: Needle-punched connection between lace fabric and base fabric

[0021] The lace fabric and the base fabric are simultaneously stretched and flattened by an unwinding machine and fed to a bidirectional needle punching machine. The bidirectional needle punching machine fixes the lace fabric to the base fabric through needle punching weaving, resulting in a needle-reinforced double-material primary bonding composite fabric. During the needle punching process, when the needle pierces the fibers of the lace fabric, the hooks on the needles carry the lace fibers from the lace fabric as they make down-needle and back-needle movements in the base fabric. When the needle returns to its original position, the hooks face upwards, and the lace fibers detach from the hooks. Some lace fibers remain in the base fabric, while others remain on the back side of the base fabric. The forked needles are used to insert or remove the lace fibers into the base fabric. Through needle punching weaving, the lace fibers and the base fabric are combined to obtain a double-material primary bonding composite fabric.

[0022] S2: High-pressure air weaving is used to reinforce the connection of the two-material primary bonding composite fabric.

[0023] The dual-material primary connection composite fabric obtained by S1 is connected by high-pressure air weaving, so that the lace fibers in the lace fabric that are needle-punched and inserted through the base fabric are implanted into the base fabric by reverse misalignment high-pressure jet air weaving through the high-pressure air weaving machine, thereby realizing the secondary reverse misalignment air weaving entanglement connection between the lace fabric and the base fabric, and obtaining the dual-material reinforced air weaving fabric.

[0024] S3: The double-layer reinforced aero-woven fabric obtained in S2 is subjected to double-sided synchronous high-temperature steam rolling ironing using a high-temperature steam rolling ironing machine to obtain a high-end composite finished fabric with a firmly connected and smooth lace fabric. The high-end composite finished fabric is then pulled and wound up by a winding machine. When high-temperature steam rolling ironing is required on the double-layer reinforced aero-woven fabric, the fabric is wound around the steam rolling rollers and pulled and wound up by the winding machine under the pressure of the temperature-controlled rolling rollers. During high-temperature steam rolling ironing, the base fabric side of the double-layer reinforced aero-woven fabric is first sprayed with humidifier from the spray nozzle to moisten its surface. Then, 6-10 kg of high-temperature, high-pressure steam is input into the hollow fixed roller. The high-temperature, high-pressure steam is sprayed through the steam nozzles to all the small air jet holes on the rotating rollers corresponding to the area covered by the double-layer reinforced aero-woven fabric. The high-temperature, high-pressure steam jet is then applied to the lace fabric side of the double-layer reinforced aero-woven fabric by the fixed roller wrapping ring. Steam rolling ironing is performed on one side of the base fabric of the double-layer reinforced air-woven fabric, while temperature-controlled rolling rollers perform high-temperature, moist rolling ironing. During the high-temperature steam rolling ironing process, the temperature of the temperature-controlled rolling rollers can be adjusted, and the rolling pressure on the double-layer reinforced air-woven fabric can be increased or decreased by changing the center distance between the temperature-controlled rolling rollers and the steam rolling rollers. The steam pressure of the high-temperature steam rolling ironing machine is 6-8 kg, and the air extraction pressure is 0.5-2 kg, thereby achieving the predetermined high-temperature steam rolling ironing effect. In the needle-punched air-woven steam rolling and pressing lace non-adhesive composite fabric, the base fabric is wool, various types of velvet, composite fabric, or non-woven fabric.

[0025] Because the lace fabric and the base fabric are joined by a double-pronged, purely physical weaving scheme of needle punching and high-pressure air weaving, the connection between the lace fibers in the lace fabric and the base fabric is stronger. A unique double-sided high-temperature steam rolling ironing method is used, which allows for adjustment of both the rolling pressure and temperature, achieving continuous and efficient high-temperature steam rolling ironing. Through continuous rolling and pressing, the gaps between the fibers in the composite fabric are further compressed, improving the density and connection strength of the composite fabric after the lace fabric and base fabric are joined, thus enhancing the composite effect between the lace fabric and the base fabric. This steam rolling ironing method does not damage either the lace fabric or the base fabric, allowing the lace pattern, surface texture, and visual effect to be better preserved. Repeated washing will not cause deformation, distortion, or separation between the lace fabric and the base fabric, maintaining the lightweight and transparent texture of the lace fabric in the composite fabric for a long time, possessing an elegant and mysterious artistic effect, further improving the connection and composite effect between the lace fabric and the base fabric, and meeting the fashion requirements pursued by modern women. This ensures that garments made from this high-end lace composite fabric will remain fashionable for a long time, maintaining their sophisticated and elegant appearance.

[0026] This invention eliminates the use of any adhesives in the lamination process between lace fabric and base fabric. It avoids traditional lamination procedures such as heating to melt the adhesive, cooling to cure, and removing the adhesive. Instead, it employs a two-step purely physical bonding process followed by a rolling and ironing step. This process effectively compresses the fiber density in the base fabric, removes dust, and eliminates deformation and misshapen defects caused by degumming and uneven fiber shrinkage after washing. This invention is more environmentally friendly, energy-efficient, reliable, and stable, with significantly improved washability, resistance to deformation and misshapenness, and anti-separation properties, meeting the requirements of high-end clothing.

Detailed Implementation

[0034] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings:

[0035] Example 1: A needle-punched, air-woven, steam-rolled, and press-bonded lace-free composite fabric, such as... Figure 1-6 As shown, the fabric includes lace fabric 7 and base fabric 6. The lace fabric 7 and base fabric 6 are knitted together by a bidirectional needle punching machine 2 to obtain a double-material primary bonding composite fabric 8. Then, it is woven by a high-pressure air loom 3 under pulsed reverse air pressure. During this process, the lace fibers 71 in the lace fabric 7 that pass through the base fabric 6 are irregularly misaligned and implanted into the base fabric 6 in the reverse direction. Under the pulsating impact of the high-pressure air pressure, the lace fibers 71 in the lace fabric 7 that are driven by needle punching are implanted into the base fabric 6, and the fibers in the base fabric 6 are compressed and contracted. This process combines pure physical needle punching and air weaving. The double weaving method achieves the irregular interweaving and penetration of pure fibers between the lace fabric 7 and the base fabric 6 to create a double-reinforced air-woven fabric 9. The double-reinforced air-woven fabric 9 is then continuously ironed by a synchronous high-temperature steam rolling ironing machine 4 to obtain a high-end composite finished fabric 10 with a firm interpenetration and smooth ironing of the two fabrics. No adhesive materials are used in the needle punching, air weaving and high-pressure steam rolling continuous ironing process of the lace fabric 7 and the base fabric 6. The lace fabric 7 and the base fabric 6 are firmly connected as a pure physical composite weaving structure.

[0036] The production method of the glue-free needle-punched air-woven steam rolling press lace composite fabric includes the following three steps:

[0037] S1: Needle-punched connection between lace fabric 7 and base fabric 6

[0038] The lace fabric 7 and the base fabric 6 are simultaneously stretched and flattened by the unwinding machine 1 and fed to the bidirectional needle punching machine 2. The bidirectional needle punching machine 2 fixes the lace fabric 7 onto the base fabric 6 through needle punching weaving to obtain a needle-reinforced double-material primary connection composite fabric 8. During the needle punching process, when the needle pierces the fibers of the lace fabric 7, the hooks on the needle carry the lace fibers 71 on the lace fabric 7 as they go down and back in the base fabric 6. When the needle goes back, the hooks are facing upwards, and the lace fibers 71 are detached from the hooks. Some of the lace fibers 71 will remain in the base fabric 6, and some of the lace fibers 71 will remain on the back of the base fabric 6. The forked needles are used to insert or remove the lace fibers 71 into the base fabric 6. Through needle punching weaving, the lace fibers 71 and the base fabric 6 obtain a double-material primary connection composite fabric 8.

[0039] S2: High-pressure air weaving reinforcement bonding of the double-material primary bonding composite fabric 8 is performed using a high-pressure air loom 3.

[0040] The dual-material primary connection composite fabric 8 obtained by S1 is connected by high-pressure air weaving, so that the lace fibers 71 in the lace fabric 7 that are needle-punched and carried through the base fabric 6 are implanted into the base fabric 6 by high-pressure air weaving machine 3 in a reverse misaligned high-pressure jet air weaving manner, thereby realizing the secondary reverse misaligned air weaving entanglement connection between the lace fabric 7 and the base fabric 6, and obtaining the dual-material reinforced air weaving fabric 9.

[0041] S3: The double-reinforced air-woven fabric 9 obtained in S2 is subjected to double-sided synchronous high-temperature steam rolling ironing by a high-temperature steam rolling ironing machine 4 to obtain a high-end composite finished fabric 10 with a firm connection and flatness of the lace fabric. The high-end composite finished fabric 10 is pulled and wound by a winding machine 5.

[0042] In this example, the high-pressure air loom 3 includes a high-pressure air chamber 31, a pneumatic jet roller 32, a pressure regulating valve 33, and a high-pressure air source 34. The high-pressure air source 34 is connected to the axial high-pressure chamber 321 of the pneumatic jet roller 32 through the pressure regulating valve 33. The pneumatic jet roller 32 is a hollow structure, including an axial high-pressure chamber 321, a fixed cylinder 322, and a rotating cylinder 323. The rotating cylinder 323 is fitted onto the fixed cylinder 322 and can rotate freely relative to the fixed cylinder 322. An air outlet 324 is provided on the outer wall of the fixed cylinder 322, and the air outlet 324 is located within the arc segment that contacts the needle-punched composite fabric. A forward jet hole 325, a vertical jet hole 326, and a reverse jet hole 327 are provided on the outer circular wall of the rotating cylinder 323. When the double-material primary bonding composite fabric 8 rotates along the rotating cylinder 323, the forward jet hole 325... Air holes 325, vertical jet holes 326, and reverse jet holes 327 are spaced apart circumferentially or axially. Specifically, along the circumferential direction, the air stream of the forward jet hole 325 is inclined to the left, the air stream of the vertical jet hole 326 is perpendicular to the side of the needle-punched composite fabric, and the air stream of the reverse jet hole 327 is inclined to the right. Along the axial direction, the air stream of the forward jet hole 325 is inclined to the front, the air stream of the vertical jet hole 326 is perpendicular to the side of the needle-punched composite fabric, and the air stream of the reverse jet hole 327 is inclined to the rear. The high-pressure gas ejected from the forward jet hole 325, vertical jet hole 326, and reverse jet hole 327 forces the outer end of the lace fiber 71 to be implanted into the base fabric 6 in different locations and in different directions, thereby achieving a multi-dimensional and firm entanglement and connection between the lace fiber and the base fabric 6, and achieving a secondary reinforcement connection through high-pressure air weaving.

[0043] The forward jet hole 325, vertical jet hole 326 and reverse jet hole 327 are all designed as pressurized nozzles with a small outlet cross section and a large inlet cross section, which improves the air weaving effect.

[0044] The high-temperature steam rolling ironing machine 4 used in the production of needle-punched air-woven steam-rolled pressed lace non-adhesive composite fabric includes a steam rolling roller 41, a spray nozzle 42, and a temperature-regulating rolling roller 43. The temperature-regulating rolling roller 43 is located on one side of the steam rolling roller 41, and the center distance between the temperature-regulating rolling roller 43 and the steam rolling roller 41 is adjustable. The double-material reinforced air-woven fabric 9 is located between the temperature-regulating rolling roller 43 and the steam rolling roller 41. The spray nozzle 42 is located on one side of the base fabric 6 of the double-material reinforced air-woven fabric 9 and is located before the double-material reinforced air-woven fabric 9 is subjected to steam rolling ironing. The steam rolling roller 41 includes a hollow fixed roller 411, a rotating roller 412, and... A fixed roller covering ring 413 and a rotating roller 412 are fitted onto the outer circle of a hollow fixed roller 411. The fixed roller covering ring 413 is fixed onto the outer circle of the rotating roller 412. A steam injection hole 414 is provided on the outer circle of the hollow fixed roller 411. The steam injection hole 414 is distributed on the arc section where the steam rolling roller 41 and the double-material reinforced air-woven fabric 9 are wrapped. Small air injection holes 415 are evenly provided on the outer wall of the rotating roller 412. The small air injection holes 415 are pressurized nozzles with a small outlet cross section and a large inlet cross section. The temperature-regulating rolling roller 43 includes a temperature-regulating roller 431 and a pressure roller covering ring 432. The pressure roller covering ring 432 is fixed on the outer circle of the temperature-regulating roller 431.

[0045] The high-temperature steam rolling ironing machine 4 is used as follows: When high-temperature steam rolling ironing is required on the double-layer reinforced air-woven fabric 9, the double-layer reinforced air-woven fabric 9 is wound around the steam rolling roller 41 and under the pressure of the temperature-regulating rolling roller 43, it is pulled and wound by the winding machine 5. During high-temperature steam rolling ironing, the spray nozzle 42 is first sprayed onto one side of the base fabric 6 of the double-layer reinforced air-woven fabric 9 to humidify its surface. Then, 6-10 kg of high-temperature and high-pressure steam is input into the hollow fixed roller 411. The high-temperature and high-pressure steam is directed through the steam injection hole 414 to all the small air injection holes 415 on the rotating roller 412 corresponding to the area covered by the double-layer reinforced air-woven fabric 9. A high-temperature, high-pressure steam jet is ejected and, via a fixed-roller wrapping ring 413, performs high-temperature steam rolling and ironing on the lace fabric side of the double-layer reinforced air-woven fabric 9. Meanwhile, a temperature-adjustable rolling roller 43 performs high-temperature, moist rolling and ironing on the base fabric 6 side of the double-layer reinforced air-woven fabric 9. During the high-temperature steam rolling and ironing process, the temperature of the temperature-adjustable rolling roller 43 is adjustable, and the rolling pressure on the double-layer reinforced air-woven fabric 9 is increased or decreased by changing the center distance between the temperature-adjustable rolling roller 43 and the steam rolling roller 41. The steam pressure of the high-temperature steam rolling and ironing machine 4 is 6-8 kg, and the suction pressure is 0.5-2 kg, thereby achieving the desired high-temperature steam rolling and ironing effect.

[0046] Because the lace fabric and the base fabric are joined by a double-pronged, purely physical weaving scheme of needle punching and high-pressure air weaving, the connection between the lace fibers in the lace fabric and the base fabric is stronger. A unique double-sided high-temperature steam rolling ironing method is used, which allows for adjustment of both the rolling pressure and temperature, achieving continuous and efficient high-temperature steam rolling ironing. Through continuous rolling and pressing, the gaps between the fibers in the composite fabric are further compressed, improving the density and connection strength of the composite fabric after the lace fabric and base fabric are joined, thus enhancing the composite effect between the lace fabric and the base fabric. This steam rolling ironing method does not damage either the lace fabric or the base fabric, allowing the lace pattern, surface texture, and visual effect to be better preserved. Repeated washing will not cause deformation, distortion, or separation between the lace fabric and the base fabric, maintaining the lightweight and transparent texture of the lace fabric in the composite fabric for a long time, possessing an elegant and mysterious artistic effect, further improving the connection and composite effect between the lace fabric and the base fabric, and meeting the fashion requirements pursued by modern women. This ensures that garments made from this high-end lace composite fabric will remain fashionable for a long time, maintaining their sophisticated and elegant appearance.

[0047] This invention eliminates the use of any adhesives in the lamination process between lace fabric and base fabric. It avoids traditional lamination procedures such as heating to melt the adhesive, cooling to cure, and removing the adhesive. Instead, a rolling and ironing process is added after a two-step purely physical bonding process. This process not only compresses the fiber density in the base fabric to achieve a denser bond but also removes dust from the base fabric. It eliminates deformation and misshapen defects caused by degumming and uneven fiber shrinkage after washing. This invention is more environmentally friendly, more energy-efficient, more reliable and stable, and exhibits significantly improved wash resistance, deformation resistance, and anti-deformation properties, meeting the requirements of high-end clothing.

[0048] This example describes the composite structure and production method of lace fabric and woolen fabric. It is also applicable to other decorative fabrics similar to lace fabric and other types of base fabrics, such as various types of velvet, composite fabrics or non-woven fabrics.

[0049] Although the embodiments of this utility model have been disclosed above, they are not limited to the specific applications listed in the specification and embodiments. Any scheme that does not use any glue between the lace fabric and the base fabric, but only uses needle punching and air weaving as pure physical weaving, and then uses high-temperature steam rolling ironing, is within the protection scope of this utility model.
