Description

Technical Field

[0001] This invention relates to the field of textile fabrics, specifically to multi-component mesh composite yarn fabrics and their preparation process. Background Technology

[0002] Composite yarn fabric is a fabric formed by combining two or more different fiber materials through textile processing. Composite yarn fabric can be a combination of silk and materials such as cotton, linen, or synthetic fibers, or it can be a combination of two different synthetic fibers, cotton, or linen. Because composite yarn fabric is highly breathable, wrinkle-resistant, and comfortable to the touch, it is very suitable for various occasions, such as clothing and home furnishings. Especially in summer, wearing clothing or bedding made of composite yarn fabric can effectively reduce sweating, making people feel more comfortable. However, existing composite yarn production processes produce yarns and fabrics with relatively limited performance characteristics; while increasing softness, the strength of the yarn is reduced. Therefore, this paper addresses this issue. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems through multi-component mesh composite yarn fabric and its preparation process.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-component mesh composite yarn fabric, characterized in that: the multi-component mesh composite yarn fabric has a honeycomb structure, its yarn is a mesh composite yarn, and white star patterns are distributed on the multi-component mesh composite yarn fabric.

[0005] Preferably, the honeycomb structure has a total of 8 warp yarns and a total of 10 weft yarns.

[0006] Preferably, the mesh composite yarn is made of interwoven polyester filaments, interspersed with acrylic fiber fluff.

[0007] The preparation process of multi-component mesh composite yarn fabric includes the following steps: Step a: Prepare mesh composite wires; Step b: Prepare a multi-component mesh composite yarn fabric with a honeycomb structure using mesh composite yarn; Step c: Dye the multi-component mesh composite yarn fabric; Step d: Perform finishing on the multi-component mesh composite yarn fabric.

[0008] Preferably, in step a, the mesh composite yarn is produced by a composite yarn processing device. The composite yarn processing device includes an atomizer, a fiber opener, and a core-mixing device in sequence from the feed end to the discharge end. The polyester filament first passes through the atomizer for humidification to improve conductivity. Then, a high-voltage electric field is applied through the fiber opener to apply the same charge to each filament of the polyester filament, so that the polyester filament is in a loose and open state. Finally, acrylic fly filaments are fed into the core-mixing device. The acrylic fly filaments are mixed into the polyester filaments and intertwine under the action of high-pressure airflow. The location of the acrylic fly filaments forms a knot yarn.

[0009] Preferably, the atomizer includes an atomizer housing and an ultrasonic generator. The atomizer housing has a cavity for containing water, and the side wall of the atomizer housing has an opening for polyester filaments to enter. The ultrasonic generator is located at the bottom of the cavity.

[0010] Preferably, the fiber opener includes an insulating shell, a positive electrode guide tube, a negative electrode guide tube, and a high-voltage power supply. The positive electrode guide tube is fixed inside the insulating shell near the feed end, and the negative electrode guide tube is fixed inside the insulating shell near the discharge end. The positive and negative electrode guide tubes do not contact each other. The positive electrode guide tube has a tubular channel inside and is connected to the positive terminal of the high-voltage power supply. The negative electrode guide tube has a conical channel communicating with the tubular channel and is grounded. The discharge end of the positive electrode guide tube extends into the conical channel of the negative electrode guide tube. The voltage of the high-voltage power supply is 800-800V.

[0011] Preferably, the impurity core device includes an impurity core tube, a fly ash feed tube, a high-pressure airflow tube, and a high-pressure air nozzle. The fly ash feed tube is located near the feed end of the impurity core tube, and the high-pressure airflow tube is located near the discharge end of the impurity core tube. The impurity core tube has an impurity core channel inside with a diameter that gradually decreases from the feed end to the discharge end.

[0012] Preferably, the high-pressure air nozzle is rotatably mounted on the side wall of the mixed core tube, the inlet of the high-pressure air nozzle is connected to the high-pressure airflow pipe, the outlet is connected to the mixed core channel, and the rotation angle of the high-pressure air nozzle is 20-30 degrees.

[0013] Preferably, the mesh composite yarn is prepared by a composite yarn processing device and then subjected to enhanced twisting, heat setting and detwisting treatment on a false twisting machine.

[0014] As can be seen from the above description, the multi-component mesh composite yarn fabric and its preparation process provided by the present invention have the following beneficial effects: the fabric is dyed with polyester using a single dyeing method. During the blending process, the mesh composite yarn is mixed with acrylic fly filaments and wrapped in the yarn body, resulting in larger local yarn knots. These knots will not be dyed during single dyeing, forming white blanks. Therefore, a white star pattern in the shape of yarn knots is formed on the fabric, which has a unique artistic effect. The honeycomb structure of the fabric has a soft hand feel, high moisture absorption, and strong three-dimensional effect. In addition, the mesh composite yarn itself has high elasticity, high moisture absorption, and high strength, resulting in excellent overall performance of the product. Attached Figure Description

[0015] Figure 1 This is a diagram showing the microstructure of the multi-component mesh composite yarn fabric of the present invention.

[0016] Figure 2 This is a schematic diagram of the composite wire processing device. Detailed Implementation

[0017] The present invention will be further described below through specific embodiments.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 As shown, the multi-component mesh composite yarn fabric of the present invention has a honeycomb structure, and its yarns are mesh composite yarns. White star-shaped patterns are distributed on the fabric. After weaving and dyeing, the surface of the multi-component mesh composite yarn fabric is covered with white star-shaped spots, creating a unique artistic effect. These white star-shaped spots are formed by acrylic fiber fluff interspersed within the mesh composite yarns, which remains uncolored after the fabric has undergone single dyeing.

[0020] The honeycomb weave has a total of 8 warp threads and 10 weft threads. (See attached image.) Figure 1 The diagram shows the fabric weave pattern. Warp yarns are labeled with Arabic numerals, and weft yarns with letters. At the warp and weft interlacing points, where the warp yarns are above the weft yarns, this is the warp weave point, marked with the weft symbol "■". At the weft interlacing points, where the weft yarns are above the warp yarns, this is the weft weave point, marked with the weft symbol "□". The lining layer of this invention is woven according to the machine diagram shown in the attached figure. It has a stable structure and a fine surface. The honeycomb weave structure of the fabric is soft to the touch, highly absorbent, and has a strong three-dimensional effect. Combined with the high elasticity, high absorbency, and high strength of the mesh composite yarn itself, the overall performance of the product is excellent.

[0021] The mesh composite yarn is made of interwoven polyester filaments, interspersed with acrylic fly yarn. The fabric is dyed using a single dyeing method on the polyester. During the blending process, the mesh composite yarn is mixed with acrylic fly yarn, which is wrapped in the yarn body, resulting in larger local yarn knots. These knots are not dyed during the single dyeing process, forming white star-shaped patterns on the fabric.

[0022] The preparation process of multi-component mesh composite yarn fabric includes the following steps: Step a: Prepare mesh composite wires; Step b: Prepare a multi-component mesh composite yarn fabric with a honeycomb structure using mesh composite yarn; Step c: Dye the multi-component mesh composite yarn fabric; Step d: Perform finishing on the multi-component mesh composite yarn fabric.

[0023] In step a, the mesh composite yarn is produced by a composite yarn processing device, such as... Figure 2 As shown, the composite yarn processing device includes an atomizer 1, a fiber opener 2, and a core-mixing device 3 in sequence from the feed end to the discharge end. The polyester filament 100 first passes through the atomizer 1 for humidification to improve conductivity. Then, a high-voltage electric field is applied through the fiber opener 2 to apply the same charge to each filament of the polyester filament 100, so that the polyester filament 100 is in a loose and open state. Finally, in the core-mixing device 3, acrylic fly filaments are fed in. The acrylic fly filaments are mixed into the polyester filaments and intertwine under the action of high-pressure airflow. The location of the acrylic fly filaments forms yarn knots, thereby forming a multi-component mesh composite yarn 200. Acrylic fly fibers are formed by crushing and breaking down acrylic short fibers into shape using a high-speed crusher. The mesh composite yarn prepared by the above process contains acrylic fly fibers, and the resulting white yarn knots form white star spots during subsequent fabric dyeing. Because the fibers are opened first and then interlaced, the tightness of the interlacing can be improved, and the fibers form a spiral curl with greater elasticity, more pores, and good moisture absorption and hand feel.

[0024] The atomizer 1 includes an atomizer housing 11 and an ultrasonic generator 12. The atomizer housing 11 has a cavity for containing water, and the side wall of the atomizer housing 11 has an opening for polyester filaments to enter. The ultrasonic generator 12 is located at the bottom of the cavity. When the polyester filaments enter the atomizer 1, the ultrasonic generator 12 generates water mist that adheres to the surface of the filaments, thereby improving the conductivity of the polyester filaments and facilitating subsequent energization and fiber opening.

[0025] The fiber opener 2 includes an insulating housing 21, a positive electrode guide tube 22, a negative electrode guide tube 23, and a high-voltage power supply 24. The positive electrode guide tube 22 is fixed inside the insulating housing 21 near the feed end, and the negative electrode guide tube 23 is fixed inside the insulating housing 21 near the discharge end. The positive electrode guide tube 22 and the negative electrode guide tube 23 do not contact each other. The positive electrode guide tube 22 has a tubular channel inside and is connected to the positive terminal of the high-voltage power supply 24. The negative electrode guide tube 23 has a conical channel communicating with the tubular channel. The negative electrode guide tube 23 is grounded. The discharge end of the positive electrode guide tube 22 extends into the conical channel of the negative electrode guide tube 23. The voltage of the high-voltage power supply 24 is 800-800V. The working principle of the fiber opener 2 is as follows: when the untwisted polyester filament passes through the positive electrode guide tube 22, it is given the same charge. When it enters the conical channel, the polyester composite filament opens up due to the repulsion of like charges and becomes an open fiber state.

[0026] The core-mixing device 3 includes a core-mixing tube 31, a fly filament feed pipe 32, a high-pressure airflow pipe 33, and a high-pressure air nozzle 34. The fly filament feed pipe 32 is located near the feed end of the core-mixing tube 31, and the high-pressure airflow pipe 33 is located near the discharge end of the core-mixing tube 31. The core-mixing tube 31 has a core-mixing channel with a diameter that gradually decreases from the feed end to the discharge end. The high-pressure airflow from the high-pressure airflow pipe 33 enters the core-mixing channel through the high-pressure air nozzle 34. The polyester filaments are impacted laterally by the high-pressure airflow, and the fibers are broken open. After entering the core-mixing channel from the middle, the high-pressure airflow forms a folding airflow on both sides. Due to the convergence of strong and weak airflows, a turbulent airflow is formed, causing the fibers to entangle with each other and form network nodes. Under the drive of the high-pressure airflow, the acrylic fly filaments enter the core-mixing channel from the fly filament feed pipe 32 and are mixed with the polyester filaments in the open fiber state. Under the action of the high-pressure airflow, they are covered together in the network nodes, forming blank nodes.

[0027] The high-pressure air nozzle 34 is rotatably mounted on the side wall of the mixed core tube 31. The inlet of the high-pressure air nozzle 34 is connected to the high-pressure airflow pipe 33, and the outlet is connected to the mixed core channel. The rotation angle of the high-pressure air nozzle 34 is 20-30 degrees. Since the high-pressure air nozzle 34 is rotatable, the jet angle of its airflow can be adjusted. It can be injected into the mixed core channel vertically or at an angle. When the airflow direction is inclined and consistent with the advance of the filament bundle, it can reduce the resistance of the filament bundle, reduce the number of nodes, and improve production efficiency. When the airflow is injected vertically, the number of nodes increases and the degree of interlacing increases.

[0028] After being prepared by a composite yarn processing device, the mesh composite yarn undergoes strengthening twisting, heat setting and detwisting treatment on a false twisting machine.

[0029] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
