Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to an air-textured yarn with soft hand feeling, fine velvet feeling and good anti-pilling performance. Background Art

[0002] With the continuous improvement of people's living standards, the weaving levels and types of textiles are increasing, and the research on new chemical fiber simulation fibers is becoming more and more in-depth. Among them, air-deformed silk is a large category of simulation fibers.

[0003] Air-textured yarn, as the name implies, uses compressed air to jet-deform the filaments of chemical fibers, causing the outer ring of the filament bundle to curl locally, and then partially break it to form several ends exposed outside, which looks very similar to air-textured yarn obtained by spinning with short fibers in conventional methods. The production of air-textured yarn omits the process of cutting the chemical fiber filaments and spinning them into yarns. The fabric woven by the air-textured machine has an appearance and feel similar to that of fabrics woven with short fibers, and is also hygroscopic. Air-textured yarn can be used to produce cotton-like or wool-like fabrics, which are used as clothing, furniture fabrics or automotive fabrics respectively.

[0004] The style of air-textured yarn is affected by many factors, such as the nozzle airflow, nozzle direction, grinding method and yarn combination method, which will change the style of the yarn. How to form yarn with better feel and better style through the design of nozzle airflow, yarn combination, yarn combination method and yarn feeding method is the main idea for developing air-textured yarn in the market. Summary of the invention

[0005] The object of the present invention is to provide an air-textured yarn which has a soft hand feeling, a fine velvety feeling and good anti-pilling performance.

[0006] The technical scheme adopted by the present invention is: an air-textured yarn is composited by four different spinning lines, which are respectively two fine-denier polyester DTY yarns of different specifications and two fine-denier polyester FDY yarns of different specifications; wherein the two fine-denier polyester DTY yarns of different specifications pass through a first cleaning device at the same time, and then pass through a bundling device at the same time and are combined into a composite yarn bundle; the two fine-denier polyester FDY yarns of different specifications pass through a second cleaning device and a third cleaning device respectively, and then pass through an air texturing machine nozzle together with the composite yarn bundle; an air baffle is arranged at the nozzle outlet position; The plate, the first compressed air system and the second compressed air system respectively blow compressed air into the nozzle to spray the fiber filaments, so that they are blown away and form fluffy wire loops and wire arcs, thereby obtaining air-deformed wires with many wire loops and wire arcs on the surface; the air-deformed wires are introduced into the bristle grinding device through the wire guide roller for bristle grinding treatment, and the air-deformed wires after the bristle grinding treatment enter the heat setting device through the wire guide roller for setting treatment, thereby increasing the stability of the air-deformed wires, and the air-deformed wires after the setting treatment are wound by the winding device to form a wire cake.

[0007] Furthermore, the bristle grinding and brushing device comprises a blower, a first friction roller, a second friction roller, a bristle brushing roller, an exhaust fan and a fluff collecting bag.

[0008] Furthermore, the specific process of the air-deformed wire in the bristle sanding brush device is as follows: after the air-deformed wire passes through the wire guide roller and enters the bristle sanding brush device, it first enters the first friction roller and the second friction roller for sanding treatment. The first friction roller and the second friction roller turn in opposite directions, and then the air-deformed wire passes through the wire guide roller and enters the bristle brush roller for brushing treatment. During the sanding and brushing process, a blower and an exhaust fan are used to suck the fallen fluff into the fluff collection bag.

[0009] Furthermore, when the four different spinning threads pass through the first cleaning device, the second cleaning device and the third cleaning device, the cleaning device first sprays degreasing spirit on the spinning threads to remove the oil on the surface of the spinning threads, and then sprays clean water on the spinning threads for cleaning and impregnation treatment, thereby increasing the viscosity and deformation performance of the spinning threads to improve the deformation effect of the spinning threads.

[0010] Furthermore, the first compressed air system and the second compressed air system operate independently, and the two compressed air systems adjust the air pressure of the inlet and outlet compressed air according to the deformation effect required by the air deformation yarn.

[0011] Furthermore, when the air-deformed yarn treated by the bristle-brushing device is subjected to a shaping treatment, the air-deformed yarn is heated and shaped by hot air, the heat-setting temperature ranges from 160 to 170° C., and the shaping time is 25 to 28 seconds.

[0012] Furthermore, the mesh number of the sandpaper on the surface of the first friction roller and the second friction roller is 800-1000 meshes.

[0013] Furthermore, the air pressure of the compressed air entering and leaving the first compressed air system is 5-10 kg, and the air pressure of the compressed air entering and leaving the second compressed air system is 0-8 kg.

[0014] Furthermore, the specifications of the two different specifications of fine-denier polyester DTY yarns are 100D / 48F semi-bright polyester DTY and 150D / 144F semi-bright polyester DTY respectively.

[0015] Furthermore, the specifications of the two different specifications of fine-denier polyester FDY yarns are 150D / 288F semi-bright polyester FDY and 100D / 144F semi-bright polyester FDY respectively.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The air-deformed yarn of the present invention has the following advantages:

[0018] (1) The present invention subjects four different spinning lines to degreasing cleaning and impregnation treatment through a cleaning device. The cleaning device first sprays degreasing spirit on the spinning lines to remove the oil agent on the surface of the spinning lines, and then sprays clean water on the spinning lines for cleaning and impregnation treatment, thereby increasing the viscosity and deformation performance of the spinning lines to improve the deformation effect of the spinning lines.

[0019] (2) Two different specifications of fine-denier polyester DTY yarns among the four different spinning yarns of the present invention pass through the first cleaning device at the same time, and then pass through the bundling device at the same time to be combined into a composite yarn bundle; two different specifications of fine-denier polyester FDY yarns pass through the second cleaning device and the third cleaning device respectively, and then pass through the air texturing machine nozzle together with the composite yarn bundle for air deformation. By changing the way of entering the nozzle, the four different spinning yarns are subjected to bundling, combining, entering the nozzle, and winding by air deformation, making the yarn style more diverse.

[0020] (3) The first compressed air system and the second compressed air system of the present invention operate independently. The two compressed air systems adjust the air pressure of the compressed air in and out according to the deformation effect required by the air deformation yarn, thereby making it more convenient to adjust the style of the air deformation yarn.

[0021] (4) The air-deformed yarn of the present invention is treated by a brushing device and then heat-set. Heat-setting can eliminate the internal stress of the air-deformed yarn and increase the dimensional stability and hair feel stability of the yarn. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] An air-textured yarn is composited from four different spinning yarns, namely, a 100D / 48F semi-bright polyester DTY, a 150D / 144F semi-bright polyester DTY, a 150D / 288F semi-bright polyester FDY and a 100D / 144F semi-bright polyester FDY; wherein, a 100D / 48F semi-bright polyester DTY and a 150D / 144F semi-bright polyester DTY pass through a first cleaning device 1 at the same time, and then pass through a bundling device 4 at the same time and are combined into a composite yarn bundle; the two fine-denier polyester FDY yarns of different specifications pass through a second cleaning device 2 and a third cleaning device 3 respectively, and then are combined with the composite yarn bundle. The air-deformed yarn passes through the nozzle 5 of the air-deformation machine; an air baffle 8 is arranged at the outlet of the nozzle 5; the first compressed air system 6 and the second compressed air system 11 respectively blow compressed air into the nozzle 5 to spray the fiber filaments, so that they are blown away and form fluffy wire loops and wire arcs, thereby obtaining air-deformed yarns with many wire loops and wire arcs on the surface; the air-deformed yarns are introduced into the brushing device 7 through the guide roller for brushing, and the air-deformed yarns after brushing enter the heat setting device 9 through the guide roller for setting, thereby increasing the stability of the air-deformed yarns, and the air-deformed yarns after setting are wound by the winding device 10 to form a yarn cake. The brushing device 7 includes a blower 71, a first friction roller 72, a second friction roller 73, a brush roller 74, an exhaust fan 75 and a fluff collection bag 76.

[0028] The specific process of the air-deformed yarn in the bristle-brushing device 7 is as follows: after the air-deformed yarn enters the bristle-brushing device 7 through the guide roller, it first enters the first friction roller 72 and the second friction roller 73 for bristle-brushing treatment. The mesh number of the sandpaper on the surface of the first friction roller 72 and the second friction roller 73 is 1000 mesh, and the first friction roller 72 and the second friction roller 73 turn in opposite directions. Then the air-deformed yarn passes through the guide roller and enters the brush roller 73 for bristle-brushing treatment. During the bristle-brushing and bristle-brushing process, a blower 71 and an exhaust fan 75 are used to suck the fallen fluff into the fluff collection bag 76; when the four different spinning threads pass through the first cleaning device 1, the second cleaning device 2 and the third cleaning device 3, the cleaning device first sprays degreasing spirit on the spinning thread to remove the oil agent on the surface of the spinning thread, and then sprays clean water on the spinning thread for cleaning and infiltration treatment, thereby increasing the viscosity and deformation performance of the spinning thread to improve the deformation effect of the spinning thread.

[0029] The first compressed air system 6 and the second compressed air system 11 operate independently, and the two compressed air systems adjust the air pressure of the compressed air in and out according to the deformation effect required by the air-deformed yarn. The air pressure of the compressed air in and out of the first compressed air system 6 is 10kg, and the air pressure of the compressed air in and out of the second compressed air system 11 is 2kg. When the air-deformed yarn treated by the bristle-brushing device 7 is subjected to shaping treatment, the air-deformed yarn is heated and shaped by hot air, and the heat-setting temperature range is 160°C, and the shaping time is 28s.

[0030] The air-deformed yarn prepared by the above method not only has various styles but also has a wool-like feel; at the same time, the air-deformed yarn prepared by the above method has a style with fine fluff because the filaments are blown and brushed to form a style with fine fluff, so it has less hair loss and good pilling resistance.

[0031] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
