Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a lace needle-punched composite fabric product and a production method thereof. Background Art

[0002] With the improvement of living standards, people have higher requirements for their own dressing. The demand for composite clothing of lace fabric and other fabrics is increasing, and the requirements are getting higher and higher. Because lace fabric is light and transparent, with elegant and mysterious artistic effects, combining lace fabric with other fabrics is a fashion pursued by female friends.

[0003] The existing lace composite fabrics are all glue-bonded composite processes. The composite production process between lace fabrics and basic fabrics is divided into four steps, namely, preliminary preparation, dyeing, adhesive heating composite and cooling curing composite. The first step is to set the guide roller of the substrate according to the line pattern and reasonably determine the placement ratio of the adhesive. The second step is to turn on the heating device of the oven for heating. After heating to the accurate temperature, turn on the machine switch for dyeing. The dyeing step is not complicated. You only need to apply glue and dye to the substrate that has passed the anilox roller and then wait for drying. The third step is double-material glue compounding. This process is automatically produced by a compounding machine, in which the lace fabric and the base fabric are bonded together in the glued state; the fourth step is cooling to solidify the adhesive to achieve a firm compound of the two, and finally rolling up to obtain the finished product.

[0004] This bonding method is adhesive bonding. The lace composite fabric is bonded with PUR hot melt adhesive, TPU, etc. The adhesive-bonded composite fabric has poor softness and is easily deformed and wrinkled after washing. In severe cases, it is easy to delaminate, which does not meet the requirements of high-end clothing for clothing fabrics.

[0005] In order to overcome the shortcomings of the prior art, CN201910198243.3 discloses a production process for lace needle-punched composite fabrics. The method includes: pretreatment, dyeing, compounding of the surface fabric and the base fabric, cooling and shaping, and subsequent treatment. The surface fabric is made of lace material. In the compounding process, the fibers of the surface fabric and the base fabric are entangled and embraced by the needle-punching process, and the composite fabric is formed by needle-punching reinforcement; before the needle-punching process, a layer of hot-melt adhesive film is laid on the surface of the surface fabric. After the needle-punching is completed, the hot-melt adhesive film is torn off, and then a heating compounding operation is performed.

[0006] In this lace needle-punched composite fabric production process, hot melt adhesive is introduced into the fabric fibers through the needle during needle-punching. After the hot melt adhesive is heated and dissolved, the lace fibers and the base fabric fibers are bonded together, and the composite effect is improved through the simultaneous action of needle-punched composite and adhesive composite. Compared with the traditional lace adhesive composite method, the actual amount of glue used in the production of lace needle-punched composite fabrics by this method is less, the glue content in the fabric is low, the fabric feels softer, and the washing resistance and anti-delamination performance are improved. However, it still needs to lay a layer of hot melt adhesive film on the surface of the face cloth before composite. After the needle-punching is completed, the hot melt adhesive film is torn off, and then the heating composite operation is performed. The resulting composite fabric will still be deformed after washing, and still cannot meet the performance requirements of high-end clothing for lace needle-punched composite fabrics in terms of anti-deformation, anti-wrinkling and anti-delamination. It is easy to wrinkle, easy to deform, easy to pilling, and has poor wear resistance; the color stability is poor, and after repeated washing, it will lose its original high-end atmosphere and grade texture and brightness. At the same time, this production method has many processes, a long cycle, high energy consumption, poor water washability, and does not meet environmentally friendly production requirements.

During this process, the lace fibers in the lace fabric that pass through the base fabric are reversely irregularly displaced and then implanted into the base fabric. Under the pulsating impact of the high-pressure airflow, the lace fibers in the lace fabric that are driven by the needle-punching are implanted into the base fabric, and the fibers in the base fabric are compressed and shrunk. After pure The double weaving superposition method combining physical needling and air weaving obtains double-material reinforced air-woven fabric, which realizes the irregular mutual entanglement, penetration and bonding weaving of pure fibers between lace fabric and basic fabric. The double-material reinforced air-woven fabric is obtained by continuous high-temperature steam rolling and ironing of the synchronous high-temperature steam rolling and ironing machine to obtain a high-end composite finished fabric with two fabrics firmly interpenetrated and woven and ironed flat. No adhesive material is used in the process of needling, air weaving and high-pressure steam rolling continuous ironing of the lace fabric and the basic fabric. The lace fabric and the basic fabric are a purely physical composite woven and firmly connected structure.

[0011] Furthermore, in the high-pressure air loom, the pneumatic jet roller includes an axial high-pressure chamber, a fixed cylinder and a rotating cylinder, the rotating cylinder is mounted on the fixed cylinder, the rotating cylinder can rotate freely relative to the fixed cylinder, an air outlet notch is provided on the outer wall of the fixed cylinder, the air outlet notch is opened within the range of the arc surface section in contact with the needle-punched woven composite fabric, and 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 needle-punched woven 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 end of the lace fiber to be implanted into the base fabric in different positions and in different directions in reverse, thereby realizing a multi-dimensional firm winding and embracing connection between the lace fiber and the base fabric, and realizing a secondary reinforcement connection through high-pressure air weaving.

[0012] Furthermore, in the high-pressure air loom, the forward jet holes, the vertical jet holes and the reverse jet holes are spaced apart in the circumferential direction or the axial direction.

[0016] Furthermore, in the high-temperature steam rolling ironing machine, the fine jet hole is a booster nozzle with a small outlet cross-section and a large inlet cross-section.

[0017] The method for using the high-temperature steam rolling and ironing machine is characterized in that: when it is necessary to perform high-temperature steam rolling and ironing on the double-material reinforced air-woven fabric, the double-material reinforced air-woven fabric is wound around the steam rolling wheel and is pulled and rolled up by the winder under the pressure of the temperature-adjusting rolling wheel. When performing high-temperature steam rolling and ironing, a spray nozzle is firstly used to spray and humidify the base fabric side of the double-material reinforced air-woven fabric to wet its surface, and then 6 to 10 kilograms of high-temperature and high-pressure steam is input into the hollow fixed roller, and the high-temperature and high-pressure steam is sprayed through the steam spray hole to all the fine jet holes on the rotating circle roller corresponding to the range covered by the double-material reinforced air-woven fabric. The high-temperature and high-pressure steam beam is used to perform high-temperature steam rolling and ironing on the lace fabric side of the double-material reinforced air-woven fabric through the fixed wheel cloth wrapping ring, while the temperature-adjusting rolling wheel is used to perform high-temperature wet rolling and ironing on the base fabric side of the double-material reinforced air-woven fabric.

The steam pressure of the high-temperature steam rolling and ironing machine is 6-8 kg, and the exhaust pressure is 0.5-2 kg, so as to achieve the predetermined high-temperature steam rolling and ironing effect. Furthermore, in the needle-punched, air-woven, steam-rolled and pressed lace glue-free composite fabric, the base fabric is woolen cloth, various flannels, composite fabrics or non-woven fabrics.

[0018] Since the lace fabric and the base fabric adopt a double pure physical connection weaving scheme of needle punching and high-pressure air weaving, the connection and weaving between the lace fibers in the lace fabric and the base fabric are more firmly.

The high-end composite finished fabric 10 is pulled and rolled by a winding machine 5.

[0023] In this example, the high-pressure air loom 3 includes a high-pressure air cavity 31, a pneumatic jet roller 32, a pressure regulating valve 33 and a high-pressure air source 34.

[0025] A high-temperature steam rolling and ironing machine 4 used in the production of needle-punched air-woven steam rolling pressed lace glue-free composite fabrics comprises a steam rolling wheel 41, a spray nozzle 42 and a temperature-adjusting rolling wheel 43, wherein the temperature-adjusting rolling wheel 43 is arranged on one side of the steam rolling wheel 41, and the center distance between the temperature-adjusting rolling wheel 43 and the steam rolling wheel 41 is adjustable, and the double-material reinforced air-woven fabric 9 is located between the temperature-adjusting rolling wheel 43 and the steam rolling wheel 41, and the spray nozzle 42 is arranged 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 and ironing, and the steam rolling wheel 41 comprises a hollow fixed roller 411, a rotating ring roller 412 and a The fixed wheel cloth wrapping ring 413 and the rotating circle roller 412 are sleeved on the outer circle of the hollow fixed roller 411, the fixed wheel cloth wrapping ring 413 is fixed on the outer circle of the rotating circle roller 412, and steam injection holes 414 are provided on the outer circle of the hollow fixed roller 411. The steam injection holes 414 are distributed on the arc surface section wrapped by the steam rolling wheel 41 and the double-material reinforced air-woven fabric 9, and small injection holes 415 are evenly provided on the outer circle wall of the rotating circle roller 412; the small injection holes 415 are pressurized nozzles with a small outlet cross-section and a large inlet cross-section. The temperature regulating rolling wheel 43 includes a temperature regulating wheel 431 and a pressure wheel cloth wrapping ring 432, and the pressure wheel cloth wrapping ring 432 is fixed on the outer circle of the temperature regulating wheel 431.

[0026] The method for using the high-temperature steam rolling and ironing machine 4 is as follows: when the double-material reinforced air-woven fabric 9 needs to be rolled and ironed with high-temperature steam, the double-material reinforced air-woven fabric 9 is wound around the steam rolling wheel 41 and is pulled and rolled by the winding machine 5 under the pressure of the temperature-adjusting rolling wheel 43. When the high-temperature steam rolling and ironing is performed, the spray nozzle 42 is firstly aimed at one side of the base fabric 6 of the double-material reinforced air-woven fabric 9 to spray and humidify its surface, and then 6 to 10 kilograms of high-temperature and high-pressure steam is input into the hollow fixed roller 411, and the high-temperature and high-pressure steam is injected into all the fine jet holes 415 on the rotating circle roller 412 corresponding to the range covered by the double-material reinforced air-woven fabric 9 through the steam injection hole 414.

The steam pressure of the high-temperature steam rolling and ironing machine 4 is 6-8 kg, and the exhaust pressure is 0.5-2 kg, so as to achieve the predetermined high-temperature steam rolling and ironing effect. Since the lace fabric and the base fabric adopt a double pure physical connection weaving scheme of needle punching and high-pressure air weaving, the connection and weaving between the lace fibers in the lace fabric and the base fabric are more firmly.

The gaps between the fibers in the composite fabric can be further squeezed through continuous rolling and pressing, and the density and connection firmness of the composite fabric after the lace fabric and the base fabric are connected are improved, and the composite effect between the lace fabric and the base fabric is improved. Such steam rolling and ironing method will not damage the lace fabric and the base fabric, and the pattern, surface texture and visual effect of the lace fabric can be better solidified. After repeated washing, there will be no deformation, distortion or separation between the lace fabric and the base fabric, and the lace fabric in the lace composite fabric is kept thin and transparent for a long time, with 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 female friends. This makes the clothing made of this high-end lace composite fabric never go out of style and maintain its high-end temperament for a long time.

[0027] In the process of compounding the lace fabric and the basic fabric, no colloid is used, and traditional compounding processes such as heating the sol, cooling and solidifying, and removing the glue are not required. After the two-step pure physical firm connection process, a rolling and ironing process is added, which can not only compact the fiber density in the composite basic fabric, but also remove the ash content in the basic fabric, and eliminate the deformation and distortion defects caused by degumming and uneven fiber shrinkage after washing. The present invention is more environmentally friendly, more energy-saving, and has higher reliability and stability, and its washability, deformation resistance, non-distortion, and anti-separation properties are greatly improved, which can meet the requirements of high-end clothing.

[0028] In this example, the composite structure and production method of lace fabric and woolen cloth are described, which is also applicable to other decorative fabrics similar to lace fabrics and other types of basic fabrics, such as various types of flannel, composite fabrics or non-woven fabrics.

[0029] Although the embodiments of the present invention have been disclosed as above, they are not limited to the specific applications listed in the specification and implementation methods. As long as no colloid is used between the lace fabric and the base fabric, and only a double pure physical weaving connection of needle punching and air weaving is used, and then high-temperature steam rolling and ironing are used, all solutions are within the protection scope of the present invention.
