Description

Technical Field

[0001] The invention relates to the technical field of fiber fabric impregnation finishing, and in particular to a production method and production equipment for anti-mite and antibacterial indefinite island ultrafine fibers. Background Art

[0002] Supercritical fluid technology has been widely used in fields such as fiber fabric dyeing due to its green, environmentally friendly and low operating cost characteristics. Among supercritical fluids, carbon dioxide is also a good solvent in the supercritical state because it is non-combustible, non-toxic, non-corrosive and safe. In addition, the supercritical temperature and pressure of carbon dioxide are relatively low (temperature is 31.1°C and pressure is 7.4MPa), which makes carbon dioxide stand out from many supercritical fluids. In the prior art, for example, Patent Document 1 (CN117779379A) ​​discloses a flax fiber supercritical carbon dioxide antibacterial ultraviolet finishing device and finishing method, which realizes the anti-ultraviolet finishing of flax fiber by introducing the anti-ultraviolet finishing agent into the finishing kettle, but the flax fiber is placed in the inner cylinder of the finishing kettle, and an agitator is arranged at the bottom of the inner cylinder, and the permeability of the anti-ultraviolet finishing agent is achieved by the agitator, which improves the uniformity of the anti-ultraviolet finishing to a certain extent, but because the fiber is placed in the inner cylinder of the finishing kettle as a whole, it will inevitably make the fiber impregnation effect poor, and the treated fibers may also be entangled together, affecting the fiber quality; for example, Patent Document 2 (CN118773857A) discloses a supercritical waterless overflow dyeing and printing device, system and use, which separates the reaction part and the dyeing and printing part of the supercritical fluid, and arranges the overflow to prevent the fiber from being entangled. The rod holes on the output rod realize the printing and dyeing of the textile in the atmospheric pressure reactor, so that it is possible to perform sewage supercritical dyeing on the textile under atmospheric pressure. However, the dyeing and printing channel in which the textile is located is a circular channel. The textile is directly arranged in the circular channel. It will be entangled due to the twisting of the fabric during movement. In addition to affecting the dyeing of the textile, it is also possible to cause the dyed textile to be twisted together; finally, Patent Document 3 (CN103866515A) discloses an ejector for supercritical fluid spraying, which sprays a supercritical fluid onto the surface of the dyed object through an ejector, and then the dyed object is wound around a dyeing roller. After the supercritical fluid passes through the dyeing roller, it is refluxed and collected by a reflux pipe. Since the dyeing rollers are arranged in an interlaced manner, it can dye the front and back sides of the cloth, but the dyed object is guided by the guide roller and moves in the fairing, which has the defect of dye leakage.

[0003] In summary, in the prior art, there has been a method of dyeing fiber cloth after dissolving the corresponding finishing liquid through supercritical fluid of carbon dioxide, but the cloth is placed in a dyeing kettle for cyclic dyeing, and there is no device that can directly roll up the dyed cloth and can guide the cloth well during dyeing. For this reason, the present invention provides a method and a production equipment for indefinite island ultrafine fibers, which can be carried out in a closed dyeing kettle, can guide the cloth well, can automatically roll up the cloth after the dyeing meets the dyeing requirements to a certain extent, can complete the dyeing in a closed dyeing kettle, can dye multiple rolls of cloth at the same time, and perform anti-mite and antibacterial treatment on the fiber interior and in post-finishing.

Through the above-mentioned staggered winding, by controlling the deflection of the parallelogram adjustment frame 20, the spray roller 55 can be made to impregnate the front and back sides of the indefinite island ultrafine fiber fabric, so as to better perform post-finishing treatment on the surface of the fabric.

[0023] In addition, in order to adapt to the staggered arrangement of fabrics, the surface carbon dioxide fluid can be better impregnated, such as Figure 6-Figure 7 As shown, the spray roller 55 includes a feeding inner core 33 and a plurality of spray pipes. The plurality of spray pipes each include a barrel 36 and spray holes disposed on the barrel 36 . The plurality of spray pipes are rotatably disposed on the feeding inner core 33 .

The high-pressure supercritical fluid 1 is introduced into the feed channel 42 through a pipeline (not shown in the figure), and the support 38 is arranged in the mounting hole 1 46 .

[0025] In addition, when the spraying roller 55 is the left finishing roller group 21, J=L, and when the spraying roller 55 is the right finishing roller group 22, J=S.

[0026] like Figure 7-Figure 9 As shown, the center of the lower arc plate and the upper arc plate coincides with the center of the support 38, the angle between one side edge of the lower arc plate and the horizontal line is Ω1, the angle between the other side edge of the lower arc plate and the horizontal line is Ω2, the angle between the two side edges of the lower arc plate is Ω3, then 180°<Ω3<360°, the angle between one side edge of the upper arc plate and the horizontal line is Ω4, the angle between the other side edge of the upper arc plate and the horizontal line is Ω5, the angle between the two side edges of the upper arc plate is Ω6, then 180°<Ω6<360°. Preferably, Ω1=Ω2, Ω4=Ω5, Ω3=Ω6.

[0027] like Fig.10 As shown, the first fixed guide wheel group 16 and the second fixed guide wheel group 17 have the same structure, and both include an arc-shaped baffle plate 47, a front side plate 48, a rear side plate 49, a guide nozzle 51 and a connecting bracket 50. The front side plate 48 and the rear side plate 49 are arranged on both sides of the arc-shaped baffle plate 47, and the guide nozzle 51 is rotatably arranged between the front side plate 48 and the rear side plate 49. The connecting bracket 50 is arranged on the outer side of the arc-shaped baffle plate 47, and the connecting bracket 50 is connected to the supporting beam 19.

[0028] A rotating support shaft 68 and a feeding hollow shaft 67 are respectively arranged on both sides of the guide spray barrel 51, and the rotating support shaft 68 and the feeding hollow shaft 67 are respectively rotatably arranged in the front side plate 48 and the rear side plate 49, a supporting shaft seat 2 70 is arranged on one side of the front side plate 48, and a supporting shaft seat 1 69 is arranged on one side of the rear side plate 49, and an axial hole is opened on the supporting shaft seat 1 69, so that the high-pressure supercritical fluid 1 can be fed through the feeding hollow shaft 67. Preferably, the supporting shaft seat 1 69 and the supporting shaft seat 2 70 are arranged on the front plate and the rear plate.

[0029] In addition, if Figure 6 As shown, the upper end of the support beam 19 is provided with a first mounting seat 62 and a second mounting seat 63, a first rotating shaft 64 is provided on the first mounting seat 62, a second rotating shaft 65 is provided on the second mounting seat 63, a shaft hole 1 is provided at the center of the short rod 1 66, a shaft hole 2 is provided at the center of the short rod 2 43, the first rotating shaft 64 is inserted into the shaft hole 1, and the second rotating shaft 65 is inserted into the shaft hole 2.

[0030] In addition, in order to prevent the nozzle from detaching from the feeding core during rotation, a raised ring is provided on the inner side of the nozzle, and groove rings cooperating with the raised ring are provided on the lower arc plate and the upper arc plate. In this way, it can be ensured that the nozzle can only rotate radially and cannot slide axially.

[0031] In addition, the support 38 is slidably arranged in the mounting hole 1 46, and can only slide axially along the mounting hole 1 46, and cannot rotate radially. For example, a groove is arranged in the mounting hole 1 46, and a bump is arranged in the mounting hole 1 46, so that when the parallelogram adjustment frame 20 is deflected, the spray roller 55 can slide laterally between the indefinite island microfiber fabrics and can also roll, so that the front and back sides of each indefinite island microfiber fabric can be impregnated. Of course, a telescopic adjustment cylinder can also be arranged between the end of the support 38 and the long rod 1 44, or between the end of the support 38 and the long rod 2 45, which can not only be telescopic passively, but also be actively telescopic, so that the telescopic control of the spray roller 55 can be more flexible.

[0032] The size of the angle Ω3 between the two side edges of the lower arc plate and the angle Ω4 between the one side edge of the upper arc plate and the horizontal line is related to the size of the wrap angle formed by the indefinite island ultrafine fiber fabric wrapped on the spray roller 55. When the wrap angle is large, Ω3 and Ω4 are set to be large accordingly, and when the wrap angle is small, Ω3 and Ω4 are set to be small accordingly. Through the setting of the upper arc plate and the lower arc plate, high-pressure supercritical fluid 1 can be sprayed only on the wrapped part of the fabric, which can ensure the spraying effect while saving the amount of spraying.

[0033] In addition, if Figure 2 As shown, it also includes a filtering device 3 and a reflux pump 4. The filtering device is arranged on the other side of the high-pressure supercritical fluid 1.

Through the above settings, the layout of the entire winding and unwinding roller group 14 can be made very compact. In addition, a channel groove for the entry and exit of the indefinite island microfiber fabric is provided on the inner circular frame 8. After the winding roller groups have completed the winding of the fabric, they are replaced uniformly. For example, the front panel can be opened, the winding and releasing roller group 14 is taken out and replaced with a new winding and releasing roller group 14, and then the fabric is wound on the finishing guide roller group 15. After the replacement is completed, the front panel can be covered.

[0035] Furthermore, the high-pressure supercritical fluid 1 is connected to the feeding hollow shaft 67 and the feeding channel 42 through a hose. Example 2

[0036] like Figure 11-Figure 14 As shown, the main difference between Example 2 and Example 1 is that the long rod 1 44 and the long rod 2 45 of the parallelogram adjustment frame 20 in the intermediate guide roller group 18 are different. Example 2 mainly considers the single horizontal sliding, and its impregnation action on the fabric is relatively single, thereby increasing the swing of the spray roller 55, specifically: The parallelogram adjustment frame 20 includes a long rod 1 44, a long rod 2 45, a short rod 1 66 and a short rod 2 43. The long rod 1 44 and the long rod 2 45 are parallel to each other, the short rod 1 66 and the short rod 2 43 are parallel to each other, the long rod 1 44 and the long rod 2 45 are parallel to the supporting crossbeam 19, the short rod 1 66 and the short rod 2 43 are rotatably connected to the supporting crossbeam 19, the long rod 1 44 and the long rod 2 45 are both deformed long rods 52, and a deformed long rod 52 is provided on the deformed long rod 52. A plurality of mounting holes 53 are provided, a rocker rod 54 is rotatably provided in the mounting hole 53, a mounting hole 46 is provided at both ends of the rocker rod 54, the spray roller 55 is installed on the rocker rod 54 through the mounting hole 46, a swing cylinder (not shown in the figure) is provided between the rocker rod 54 and the deformable long rod 52 so as to realize the swing of the spray roller 55, and when the spray roller 55 slides back and forth horizontally, it can also move up and down, so as to better perform the impregnation operation on the fabric.

[0037] In addition, if Fig.11 As shown, in order to make the structure more compact and to prevent the spray roller 55 from touching the deformable long rod 52 when extending and retracting, a plurality of arc grooves 58 are provided on one side of the deformable long rod 52, and the thickness of the arc groove 58 is consistent with the thickness of the swing rod 54. A first clearance hole groove 56 and a second clearance hole groove 57 are also provided on both sides of the second mounting hole 53. The opening directions of the first clearance hole groove 56 and the second clearance hole groove 57 are opposite to each other in the deformable long rod 52, so that the swing rod 54 can be received in the deformable long rod 52. When the swing rod 54 is received in the deformable long rod 52, the long sides of the deformable long rod 52 and the swing rod 54 are parallel, as shown in FIG. Fig.14 shown.

[0038] Let the center of the mounting hole 2 53 be O, then the center of the arc groove 58 is also O, the give way hole groove 1 56 and the give way hole groove 2 57 are symmetrical about the center of the circle O, the give way hole groove 1 56 and the give way hole groove 2 57 both include a first arc segment 59, a second arc segment 60 and a third arc segment 61, the third arc segment is an arc with a center of O and a radius of r4, the first arc segment is a semicircle with a radius of r2, the center of the semicircle is located on the arc with O as the center, the second arc segment is an arc with a center of O and a radius of r3, the third arc segment 61, the first arc segment 59 and the second arc segment 60 are connected in sequence, and the radius of the arc groove 58 is r1, r1>r3>r4.

[0039] Through the arrangement of the swing rod and the spray roller 55, the indefinite island ultrafine fiber fabric can be automatically interlaced and wound on the middle guide roller group 18, specifically: For the convenience of explanation, the two swing arms in the figure, the left finishing roller group 21 includes four spraying rollers 55, the right finishing roller group 22 includes four spraying rollers 55, and the nozzle includes a first nozzle and a second nozzle. When replacing a new winding and retracting roller group 14, the swing arm is as follows. Figure 11-Figure 12 As shown, it has a certain inclination angle relative to the deformed long rod, so that the upper spray roller 55 on the swing rod is higher than the upper end of the deformed long rod, and the lower spray roller 55 on the swing rod is lower than the lower end of the deformed long rod, and then the indefinite island superfine fiber fabric is wound between the first fixed guide wheel group 16 and the second fixed guide wheel group 17. At this time, the upper spray roller 55 is located above the indefinite island superfine fiber fabric, and the lower spray roller 55 is located below the indefinite island superfine fiber fabric. Then, the spray roller 55 is controlled to telescopically slide on the swing rod 54 (specifically, by The telescopic adjustment cylinder provided between the left finishing roller group 21 and the swing rod is controlled), and finally the length of the spray roller 55 of the left finishing roller group 21 is the same as the width of the left first cloth to be sorted 29, and the length of the spray roller 55 of the right finishing roller group 22 is the same as the width of the right first cloth to be sorted 31, and then the swing rod 54 is driven to rotate counterclockwise, so that the left first cloth to be sorted 29 and the right first cloth to be sorted 31 are wound together, and then the telescopic adjustment cylinder is driven to extend, so that the spray roller 55 passes through the left second cloth to be sorted 30 and the right second cloth to be sorted 32 respectively, so as to realize the staggered winding fabric arrangement.
