Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile processing machinery, and particularly relates to a melt spinning weaving device and a weaving method thereof. BACKGROUND

[0002] With the high-quality transformation and upgrading of the textile industry, future manufacturing technologies such as 3D printing, laser manufacturing and nanomanufacturing, which are dominated by new productivity, are significantly rewriting the mode and form of textile production. High-performance, multi-functional and intelligent highly customized advanced textile products have emerged as the times require, and efficient short process has become an important development direction of future manufacturing technology research. In modern weaving technology, flat knitting technology is a unique additive manufacturing technology that can realize the rapid forming and patterning of various flexible fibers through the cooperation between the needle bed and the needle. However, due to the restriction of drafting feeding and knitting unit, the needle knitting technology puts forward great requirements on the material properties, macro size and mechanical properties of the fiber. At the same time, due to the space limitation of the yarn rack of the hand-operated flat knitting machine or the computer flat knitting machine, the traditional chemical fiber needs to be reduced in size through processes such as yarn drum reversing, and the fiber raw material preparation stage is relatively cumbersome.

[0003] Melt spinning technology is a manufacturing technology with the highest production of fiber raw materials required for textile products. It mainly melts the polymer material by heating, then extrudes the melt through a spinneret, and forms a fiber by drawing and cooling. Due to its advantages such as simple process, high production efficiency and wide range of raw materials, this technology is widely used to produce various conventional synthetic fibers and high-performance, multi-functional and intelligent fibers. However, due to the limitation of the small macro size of the fiber, it still needs to be wound into a cylinder, stored and transported to the weaving factory for secondary forming to process various textile products.

[0004] At present, in the related technical concept, researchers at home and abroad have invented solution jet spinning clothing technology and demonstrated it on fashion shows, showing the concept of efficient short process from fiber to textile product. Patents CN105378162A, CN107429451A and CN115961393A propose a technology of integrated spinning and knitting based on short fiber yarn, which mainly uses the roving or spun yarn part of the short fiber yarn after spinning, rather than the full-process integrated processing of short fibers. Therefore, there is an urgent need to develop new technical solutions to simplify the existing textile structure material processing and manufacturing methods in order to improve the production efficiency and applicability of advanced fiber raw material forming and manufacturing.

[0065] Optionally, the shaping and take-up mechanism 26 is located at the lower part of the weaving unit 2. The shaping and take-up mechanism 26 includes: a base plate roller unit 261, an ultraviolet illumination device 262, a guide roller 263, and a conveyor curtain 264. The base plate roller unit 261 is located below the needle bed 232. Along the second direction, the base plate roller unit 261, the ultraviolet illumination device 262, and the guide roller 263 are distributed from top to bottom. The conveyor curtain 264 is located at the bottom of the weaving unit 2. The fabric passes through the base plate roller unit 261, the ultraviolet illumination device 262, and the guide roller 263 in sequence, and is turned and pulled by the guide roller 263 to the conveyor curtain 264 for flat collection or folding and take-up.

[0066] In some embodiments, 0.5%-10% by mass of a photocuring agent may be added to the polymer raw material to cooperate with the ultraviolet light illumination device 262 of the weaving unit 2 to improve the chemical resistance and mechanical strength of the formed fabric. The photocuring agent mainly includes a photoinitiator, an active monomer, and a prepolymer. The photoinitiator may be one of free radical or cationic polymerization initiators such as benzophenone. The active monomer may be one of monofunctional or polyfunctional polymers such as hydroxyethyl acrylate and hydroxypropyl methacrylate. The prepolymer may be one of prepolymers such as epoxy acrylate, polyurethane acrylate, polyester acrylate, and amino acrylate. The ultraviolet light illumination device 262 includes multiple illumination modules, exemplarily, such as 2-18 illumination modules, which can provide ultraviolet light curing for a set area according to the target fabric of different widths to save energy and reduce light pollution. Correspondingly, the polymer raw material containing the photocuring agent can be obtained as a filament containing the photocuring agent after passing through the spinning unit 1. The filament containing the photocuring agent can be obtained as a fabric after working together with the yarn drawing mechanism 21, the yarn feeding mechanism 22, the weaving mechanism 23, the driving mechanism 24, and the control mechanism 25. Under the traction of the bottom plate roller unit 261 below the needle bed 232, the fabric is photocured and strengthened by the ultraviolet illumination device 262 of the shaping and winding mechanism 26. Then, under the action of the guide roller 263, the fabric changes from a vertical downward movement state to a forward horizontal movement, and finally is transferred to the conveyor curtain 264 for flat collection or folding and winding.

[0067] Optionally, the needle bed 232 includes knitting needles 2321, a needle selector 2322, and a needle bed base 2323. The knitting needles 2321 are placed on the inclined part of the needle selector 2322, and the needle bed base 2323 is located below the needle selector 2322. The knitting head 231 includes an upper support arm 2311, a cam unit 2312, and an electromagnetic yarn selector 2313. The electromagnetic yarn selector 2313 and a tapered yarn guide 215 are located on the upper support arm 2311.

[0068] In this invention application, when the weaving unit 2 is working, the guide wheel assembly 211 pulls the filament from the hot drawing mechanism 15 to the drawing mechanism 21, and feeds it into the bi-directional variable speed yarn feeder 212 for speed adjustment. The speed-adjusted filament is then pulled to the variable tension pulley 213, and subsequently enters the tapered yarn guide 215 above the center of the knitting head 231. Guided by the curved inner wall of the tapered yarn guide 215, it is output to the upper end of the needle bed 232, where it is processed by the knitting mechanism 23, the drive mechanism 24, and the control mechanism 25. With the cooperation of mechanism 25, the filament moves horizontally left and right in sync with the knitting head 231. During the horizontal movement of the knitting head 231, the triangular unit 2312, in conjunction with the needle bed selector 2322, controls the knitting needle 2321 to move obliquely horizontally, so as to complete the knitting operation of the filament. The knitting operation includes loop knitting, tuck knitting, float knitting, needle turning knitting, and loop transfer knitting. After the knitting needle 2321 hooks the filament and knits it, a shaped fabric can be formed.

[0069] Optionally, the yarn feeding bracket 223 includes an upper arm and two side arms, with the upper arm connecting to the two side arms. The yarn picking frame 222 is connected to the upper arm, and the single-pass variable speed yarn storage device 224 is connected to the side arms. The yarn picking frame 222 includes: a yarn frame body 2221, a tension clamp 2222, and a yarn picking steel wire ring 2223. The tension clamp 2222 and the yarn picking steel wire ring 2223 are both connected to the yarn frame body 2221. The side yarn picking frame 251 includes: a yarn guide channel 2251, a yarn guide roller 2252, a tension spring 2253, and a side yarn picking steel wire ring 2254. The finished yarn passes through the yarn guide channel 2251, the yarn guide roller 2252, and the side yarn picking steel wire ring 2254 in sequence and is then transported to the yarn guide 227.

[0070] In this invention application, when the yarn feeding mechanism 23 of the weaving unit 2 is working, firstly, the finished yarn is led out from the yarn bobbin 221 on the frame and guided to the upper yarn take-up frame 222. Under the action of the tension clamp 2222's predetermined clamping force on the finished yarn, the finished yarn maintains a low yarn feeding fluctuation and passes through the upper front yarn take-up wire ring 2223 to further stabilize the yarn feeding tension. Then, it is led out from the upper yarn take-up frame 222 and input into the single-pass variable speed yarn storage device 224. The finished yarn is output to the lower side edge take-up. In frame 225, the finished yarn is vertically conveyed through yarn guide channel 2251 and along the second direction to the lower yarn guide roller 2252. With the assistance of the rotation of yarn guide roller 2252, the yarn passes downward through edge yarn take-up wire loop 2254 with relatively small tension resistance and is then turned and transmitted to the yarn guide 227 of weaving unit 2. The yarn feeding tension control of edge yarn take-up frame 251 is mainly controlled by tension spring 2253 below yarn guide roller 2252. The tension control magnitude is directly proportional to the stretched length of tension spring 2253.

[0071] Then, while maintaining synchronization with the weaving speed of the knitting mechanism 23, the knitting head 231 of the melt spinning weaving device draws the finished yarn on the yarn guide 227 for weaving motion. During the lateral movement of the knitting head 231, the cam unit 2312, in conjunction with the needle bed selector 2322, controls the oblique lateral movement of the needles 2321 to complete the weaving operation of the finished yarn. The weaving operation also includes loop knitting, tuck knitting, float knitting, needle turning knitting, and loop transfer. In the weaving operation, the knitting needle 2321 hooks the finished yarn and weaves it to form a shaped fabric. At the same time, the electromagnetic yarn selector 2313 and the tapered yarn guide 215 are located on the upper support arm 2311. Correspondingly, under the control of the control mechanism 25, the electromagnet on the electromagnetic yarn selector 2313 can be controlled to be energized. Thus, when weaving the finished yarn, the control head 231 can switch the control yarn guides 227 on both sides of the yarn guide slide rail group 226, which means the yarn changing operation.

[0074] Step S100: Prepare filaments;

[0075] Specifically, step S100 includes:

[0076] Step S101: The polymer raw material containing the photocuring agent is melt-plasticized through an extrusion mechanism to form a fine-flow extrusion polymer;

[0077] Specifically, step S101 includes: a screw 114 and a segmented heating box 115 for melting and plasticizing polymer raw materials. After melting and plasticizing, the polymer raw materials pass through a filter 116, a metering pump 117, a spinning box 118, and a spinneret 119 to form a fine-flow extruded polymer. The fine-flow extrusion method can be a single-hole extrusion method or a multi-hole extrusion method.

[0078] Step S102: The extruded polymer is cooled and solidified for the first time, bundled and oiled, and cooled and solidified a second time to form the precursor fiber.

[0079] Specifically, step S102 includes: the slow cooling mechanism 12 ventilates the extruded polymer to complete the first cooling and solidification; the bundling device 131 and the oiling device 132 of the bundling mechanism 13 respectively bundle and oil the polymer that has been cooled and solidified in the first cooling; and the condensing mechanism 14 uses condensate to condense the bundled and oiled polymer for the second cooling and solidification. The polymer extruded in a fine stream can form a precursor fiber after the first cooling and solidification, bundling and oiling, and the second cooling and solidification.

[0080] Step S103: The raw yarn is stretched at least once to prepare a filament;

[0081] Specifically, step S103 includes: the raw yarn passes through an upper heating and drawing tunnel 151, an upper oiling device 152, a lower heating and drawing tunnel 153, a lower oiling device 154, and a tempering tunnel 155 to form a filament. The heating temperature range of the upper heating and drawing tunnel 151 is 50℃-300℃, the heating temperature range of the lower heating and drawing tunnel 153 is 50℃-300℃, and the heating temperature range of the tempering tunnel 155 is 50℃-200℃. The diameter is D, and the diameter of the filament is DL. D = λ * DL, where λ is the draw coefficient. The value range of λ is 1-100. The value range of 1-100 can be understood as greater than or equal to 1 and less than or equal to 100, or any value between 1 and 100 or a range between any two values, such as 10, 15, 20, 25, 30, 35, 40, 35, 50, 60, 70, 80, 90, 100, or a range between any two values, etc.

[0082] Step S200: The filaments are woven to prepare a fabric;

[0083] Specifically, step S200 includes:

[0084] Step S201: The filament containing the photocuring agent is processed by at least the drawing mechanism 21, the weaving mechanism 23, the driving mechanism 24, and the control mechanism 25 to obtain the fabric.

[0085] More specifically, step S201 includes:

[0086] Step S2011: The guide wheel assembly 211 pulls the filament from the hot drawing mechanism 15 to the drawing mechanism 21, and feeds it into the dual-speed variable filament feeder 212 for speed adjustment. After speed adjustment, the filament is pulled to the variable tension pulley 213. The filament then enters the tapered guide 215 above the center of the machine head 231. Under the guidance of the curved inner wall of the tapered guide 215, it is output to the upper end of the needle bed 232.

[0087] Step S2012: With the knitting mechanism 23, drive mechanism 24 and control mechanism 25 working together, the filament moves horizontally left and right synchronously with the knitting head 231. During the horizontal movement of the knitting head 231, the cam unit 2312, together with the needle bed selector 2322, controls the knitting needle 2321 to move obliquely horizontally, so as to complete the knitting operation of the filament. The knitting operation includes loop knitting operation, tuck knitting operation, float knitting operation, needle turning knitting operation, and loop transfer knitting operation. After the knitting needle 2321 hooks the filament and performs the knitting operation, a shaped fabric is formed.

[0088] Step S300: The fabric is laid flat for collection or folded and rolled up.

[0089] Specifically, step S300 includes: the prepared fabric is pulled by the bottom plate roller unit 261 under the needle bed 232, and then photocured and strengthened by the ultraviolet illumination device 262 of the shaping and winding mechanism 26. Subsequently, under the action of the guide roller 263, the fabric changes from a vertical downward movement state to a forward horizontal movement, and finally is transferred to the conveyor curtain 264 for flat collection or folding and winding. See all the technical contents of the aforementioned shaping and winding mechanism 26.

[0090] The procedure also includes the following steps before step S100 or after step S300:

[0094] Step SX2: Lay the fabric flat and collect it or fold and roll it up.

[0095] In some embodiments, steps SX2 and S300 are exactly the same, and will not be described again here.

[0096] In some embodiments, steps S100, S200, and S300 can be executed cyclically once or multiple times, and steps SX1 and SX2 can also be executed cyclically once or multiple times.

[0097] In some embodiments, firstly, steps SX1 and SX2 can be executed cyclically once or multiple times, and then steps S100, S200, and S300 can be executed cyclically once or multiple times; or, firstly, steps S100, S200, and S300 can be executed cyclically once or multiple times, and then steps SX1 and SX2 can be executed cyclically once or multiple times.

[0098] In the melt spinning and weaving method of this invention, firstly, filaments are prepared, and then the filaments are woven to prepare fabric; or, the finished yarn is directly woven to prepare fabric. This method integrates melt spinning and filament knitting functions. Through integrated multi-level control of polymer raw materials, filaments, and knitting, it achieves short-process, high-efficiency spinning and knitting, enabling the weaving of novel knitted structural components with different fineness and tensile strength. It exhibits high adaptability to melt-spun filament fiber weaving. The melt spinning and weaving device has the technical advantages of high-efficiency and multi-functional knitting, saving many traditional time-consuming processes such as bobbin winding, bobbin rewinding, and cleaning, thus saving enterprise production costs and floor space. Enterprises can now weave and process more flexibly, greatly adapting to the future demand for efficient, short-process textile manufacturing.
