弹性纤维生产导丝装置及其在氨纶纤维生产中的用途Elastic fiber production guide wire device and its use in spandex fiber production
本发明要求2014年4月22日向中国国家知识产权局提交的、申请号为201410178507.6、名称为“弹性纤维生产导丝装置及其在氨纶纤维生产中的用途”的中国发明专利申请的优先权。The present invention claims the priority of a Chinese invention patent application filed on April 22, 2014, to the Chinese National Intellectual Property Office, with the application number 201410178507.6, entitled "Elastane Fiber Guide Wire Device and Its Use in Spandex Fiber Production".
技术领域Technical field
本发明实施例涉及纤维生产领域,具体涉及一种弹性纤维生产导丝装置及其在氨纶纤维生产中的用途。Embodiments of the present invention relate to the field of fiber production, and in particular to an elastic fiber production guide wire device and use thereof in the production of spandex fibers.
背景技术Background technique
在现有氨纶纤维的纺丝生产技术中,一个生产车间是由许多纺丝位组成;单个纺丝位由纺丝甬道、导丝装置及收卷装置所构成,收卷装置的数量与导丝装置中导丝辊的数量有关。In the spinning production technology of the existing spandex fiber, one production workshop is composed of a plurality of spinning positions; a single spinning position is composed of a spinning tunnel, a guide wire device and a winding device, and the number of winding devices and the guide wire The number of godet rollers in the device is related.
随着人们对氨纶纤维的品质要求越来越高,尤其是在氨纶纤维的后序纺织中对纤维的物理特性的一致性要求更是越来越高。氨纶纤维作为一种弹性纤维,其丝束在收卷过程中所受的张力对收卷后氨纶丝束的纤度等物理特性有重要影响。而在现有纺丝位的设置中,尤其是当上述导丝装置采用三个以上的导丝辊时,由于收卷过程中不同丝束受力情况的差异,导致收卷后氨纶丝束的纤度等物理特性存在差异,影响了氨纶纤维的品质。如果收卷后氨纶纤维的物理特性不均匀,则采用该氨纶纤维制备的布料会产生褶皱甚至发鼓,影响布料的品质。As the quality requirements of spandex fibers become higher and higher, especially in the subsequent textile of spandex fibers, the consistency of the physical properties of the fibers is becoming higher and higher. As a kind of elastic fiber, the spandex fiber has a significant influence on the physical properties such as the fineness of the spandex tow after winding. However, in the existing spinning position setting, especially when the above-mentioned guide wire device adopts more than three godet rollers, the spandex is bundled after the winding due to the difference in the force of the different tows during the winding process. There are differences in physical properties such as denier, which affects the quality of spandex fibers. If the physical properties of the spandex fibers after the winding are not uniform, the fabric prepared by using the spandex fibers may have wrinkles or even drums, which may affect the quality of the fabric.

参见图1,一种弹性纤维生产导丝装置,包括第一导丝辊1,至少一个第二导丝辊2,任一所述第二导丝辊2的下方设有至少一个喂入辊4,每个所述喂入辊4的下方设有至少一个收卷装置5。Referring to Figure 1, an elastic fiber production guide device includes a first godet roller 1, at least one second godet roller 2, and at least one feed roller 4 is disposed below any of the second godet rollers 2. At least one winding device 5 is provided below each of the feed rollers 4.

本发明实施例在具体实现过程中,可以包括一个第二导丝辊,在一个第二导丝辊的下方设置一个或多个喂入辊,每个喂入辊的下方设置一个或多个收卷装置。或者,本发明实施例弹性纤维生产导丝装置也可包括多个第二导丝辊,“任一第二导丝辊的下方设有至少一个喂入辊”,如:可以在每个第二导丝辊的下方设有一个或多个喂入辊;或者,也可以只在部分第二导丝辊下方设置一个或多个喂入辊,剩余第二导丝辊下方可以不设置喂入辊。当一个第二导丝辊下方设置有多个喂入辊时,每个喂入辊的下方设有至少一个收卷装置,如:可以在部分喂入辊下方设置一个收卷装置,而在剩余喂入辊下方设置多个收卷装置。因此本发明实施例可以包括多种实现方式,实现方式非常灵活,普适性强。In an embodiment of the present invention, a second godet roller may be included. One or more feed rollers are disposed under a second godet roller, and one or more feeds are disposed below each feed roller. Rolling device. Alternatively, the elastic fiber production guide device of the embodiment of the present invention may also include a plurality of second godet rollers, "at least one feed roller is disposed below any of the second godet rollers", such as: One or more feed rollers are disposed under the godet roller; alternatively, one or more feed rollers may be disposed only under portions of the second godet roller, and no feed roller may be disposed under the remaining second godet roller . When a plurality of feed rollers are disposed under a second godet roller, at least one winding device is disposed below each of the feed rollers, for example, a winding device can be disposed under the partial feed roller, while remaining A plurality of winding devices are disposed below the feed roller. Therefore, the embodiment of the present invention may include multiple implementation manners, and the implementation manner is very flexible and universal.
不同于非弹性纤维,弹性纤维在收卷过程中因其受到的张力而被拉伸。传统收卷技术中丝束的自由度大,要避免丝束缠绕到导丝辊上丝束所受的张力也须越大,使得收卷后纤维的预牵伸力或残余牵伸力大,由此影响弹性纤维的纤 度等物理特性;进一步的,如果采用收卷后物理特性不均匀的弹性纤维制备布料等织物,由于收卷后弹性纤维的预牵伸力或残余牵伸力存在差异,会导致所生产的布料发生褶皱甚至发鼓,影响布料的品质。而本发明实施例提出了区别于传统技术的新解决方案,通过在第二导丝辊和收卷装置之间设置喂入辊,可使现有纺丝位中从第二导丝辊至收卷装置的弹性纤维的自由度小,由此减小避免丝束缠绕在导丝辊上所需的张力,而且喂入辊是一种辊结构,辊结构对丝束的摩擦力很小,因此可在尽量不增加摩擦的基础上实现弹性纤维在较小的张力下进行收卷,避免弹性纤维在收卷生产过程中因所受张力过大而被拉伸变细,减小弹性纤维收卷后的预牵伸力或残余牵伸力,有利于保证收卷后纤维纤度的一致性,从而提高弹性纤维的产品品质以及基于该弹性纤维制备的如布料等织物的品质。Unlike non-elastic fibers, elastic fibers are stretched during the winding process due to the tension they are subjected to. In the conventional winding technology, the degree of freedom of the tow is large, and the tension required to avoid the tow wound on the godet of the godet roller must be increased, so that the pre-draw force or the residual drafting force of the fiber after winding is large. This affects the fiber of the elastic fiber Physical properties such as degree; further, if fabrics such as fabrics are prepared from elastic fibers having uneven physical properties after winding, the fabrics produced may be produced due to differences in pre-draw strength or residual drafting force of the elastic fibers after winding. Wrinkles and even drums occur, affecting the quality of the fabric. However, the embodiment of the present invention proposes a new solution that is different from the conventional technology. By providing a feeding roller between the second godet roller and the winding device, the existing spinning position can be removed from the second godet roller. The elastic fiber of the winding device has a small degree of freedom, thereby reducing the tension required to prevent the tow from being wound around the godet roller, and the feeding roller is a roller structure, and the frictional force of the roller structure to the tow is small, so The elastic fiber can be wound under a small tension without increasing the friction as much as possible, and the elastic fiber is prevented from being stretched and thinned due to excessive tension during the winding production process, and the elastic fiber winding is reduced. The post-draw force or residual drafting force is favorable for ensuring the consistency of the fiber fineness after winding, thereby improving the product quality of the elastic fiber and the quality of the fabric such as cloth prepared based on the elastic fiber.
本发明实施例提供的各技术方案可适用于各种弹性纤维的收卷控制。氨纶纤维作为弹性较大的一种弹性纤维,采用本发明实施例提供的技术方案进行收卷控制,相对于传统技术而言,在收卷后纤维纤度等物理特性的一致性方面有更好的保证。下文以氨纶纤维为例进行说明的技术方案,同样也适用其他类型的弹性纤维,不再赘述。The technical solutions provided by the embodiments of the present invention can be applied to the winding control of various elastic fibers. As a kind of elastic fiber with larger elasticity, the spandex fiber adopts the technical scheme provided by the embodiment of the invention to perform winding control, and has better consistency in physical properties such as fiber fineness after winding than the conventional technology. Guarantee. Hereinafter, the technical solution described by taking spandex fiber as an example is also applicable to other types of elastic fibers, and will not be described again.
上述技术方案中,喂入辊4可以位于第二导丝辊的正下方,以将丝束的自由程分为两段,减少丝束的自由度。或者,喂入辊4可以位于与其通过丝束3连接的第二导丝辊2的斜下方,以在实现上述目的的同时,喂入辊设置在第二导丝辊的斜下方,可改变丝束的丝路方向,可以减少一个导丝装置的横向宽度,使每个纺丝位的间距变小,节省空间,还有利于相同的空间内布置更多的收卷装置。In the above technical solution, the feeding roller 4 may be located directly below the second godet roller to divide the free path of the tow into two segments, reducing the degree of freedom of the tow. Alternatively, the feed roller 4 may be located obliquely below the second godet roller 2 connected thereto by the tow 3 to achieve the above object, while the feed roller is disposed obliquely below the second godet roller to change the filament The direction of the wire path of the bundle can reduce the lateral width of a guide wire device, making the spacing of each spinning position smaller, saving space, and also facilitating the arrangement of more winding devices in the same space.
和/或,第二导丝辊2可位于第一导丝辊1的斜上方。氨纶纤维从甬道出来需要通过导丝辊来定型,可选的需要在第一导丝辊包很大角以起到更好的定型作用,而将第二导丝辊设置在第一导丝辊的斜上方,可增大丝束与第一导丝辊和第二导丝辊的包角,便于丝束在收卷过程中的定型。And/or, the second godet roller 2 can be located obliquely above the first godet roller 1. The spandex fiber needs to be shaped by the godet roller from the tunnel. Optionally, a large angle of the first godet roller is required for better shaping, and the second godet is disposed on the first godet. Inclined upward, the wrap angle of the tow with the first godet roller and the second godet roller can be increased to facilitate the shaping of the tow during the winding process.
上述技术方案中,为了提高产能,可选的,任一第二导丝辊2的下方平行设置有至少两个喂入辊4;和/或,每个喂入辊4下方平行设置有至少两个收卷装置5。In the above technical solution, in order to increase the productivity, at least two feeding rollers 4 may be disposed in parallel below any of the second godet rollers 2; and/or at least two are disposed in parallel below each feeding roller 4. a winding device 5.
具体设置的可选形式如下所示: The optional form of the specific settings is as follows:
参见图1,一个第二导丝辊2的下方平行设置两个喂入辊4,每个喂入辊4下方设有一个收卷装置5。可选的,两个喂入辊4在该第二导丝辊2的下方平行且位于同一水平面设置。该技术方案使现有纺丝位中从甬道的出口至收卷装置的氨纶纤维的长度相同或尽可能相同,从而保证了从收卷装置生产出来氨纶纤维的物理特性一致,提高了氨纶纤维的产品品质;此外,将从第二导丝辊出来的丝束再经喂入辊进入相应收卷装置的卷轴,减小了此段丝束的张力,保证了纤维的品质。Referring to Figure 1, two feed rolls 4 are disposed in parallel below a second godet 2, and a take-up device 5 is provided below each feed roll 4. Optionally, two feed rollers 4 are arranged parallel to the second godet roller 2 and located at the same horizontal plane. The technical solution makes the length of the spandex fiber from the exit of the ramp to the winding device in the existing spinning position the same or as the same as possible, thereby ensuring the uniform physical properties of the spandex fiber produced from the winding device and improving the spandex fiber. Product quality; in addition, the tow from the second godet is fed through the feed roller into the reel of the corresponding winding device, reducing the tension of the tow and ensuring the quality of the fiber.
采用图2、图3和图4所示的纤维生产导丝装置,在实现图1所示实施例相应技术效果的基础上,还可进一步提高氨纶单个纺丝位的产能,不仅可以降低单位能耗,还可以减少单位空间。图2-图4所示的实施例均可实现四个收卷装置的设置。Using the fiber production guide wire device shown in FIG. 2, FIG. 3 and FIG. 4, on the basis of realizing the corresponding technical effects of the embodiment shown in FIG. 1, the productivity of the single spinning position of the spandex can be further improved, and the unit energy can be reduced. Consumption can also reduce unit space. The embodiment shown in Figures 2 - 4 can each achieve the arrangement of four winding devices.
参见图2,即:一个第二导丝辊2的下方平行设有四个喂入辊4,每个喂入辊4下方设有一个收卷装置5,喂入辊4和收卷装置5一一对应。Referring to Fig. 2, four feeding rollers 4 are arranged in parallel below a second godet roller 2, and a winding device 5, a feeding roller 4 and a winding device 5 are provided below each feeding roller 4. A correspondence.
参见图3,一个第二导丝辊下方设置的喂入辊4的数量小于收卷装置5的数量,多个收卷装置公用一个喂入辊,例如在一个第二导丝辊下设置四个收卷装置、且这每两个收卷装置公用一个喂入辊4,设备成本最低,且该技术方案满足了从同一第二导丝辊出来的多根丝束在进入不同收卷装置时纤维的长度一致,丝束自甬道的出口分别到不同收卷装置的各路程相同,自由度小,保证其物理特性尽可能一致,从而提高纤维的产品品质。该方案可以增加单个纺丝位的产能,例如纤维的根数增加,从而增加产品的产量。Referring to Figure 3, the number of feed rollers 4 disposed below a second godet roller is less than the number of winding devices 5, and the plurality of winder devices share a feed roller, for example, four under one second godet roller. The winding device, and each of the two winding devices shares a feeding roller 4, the equipment cost is the lowest, and the technical solution satisfies the fiber of the plurality of tows coming out from the same second godet when entering different winding devices The length of the tow is the same from the exit of the ramp to the different winding devices, and the degree of freedom is small, so that the physical properties are as uniform as possible, thereby improving the product quality of the fiber. This solution can increase the capacity of a single spinning position, such as an increase in the number of fibers, thereby increasing the yield of the product.
参见图4,第二导丝辊2为两个,多个第二导丝辊2平行设置在第一导丝辊1的斜上方,每个第二导丝辊2的下方设有两个喂入辊4,每个喂入辊4的下方设有一个收卷装置5。该技术方案满足了从同一第二导丝辊出来的多根丝束在进入不同收卷装置时纤维的长度一致,自由度小,保证其物理特性尽可能一致,从而提高纤维的产品品质。本发明实施例也可以将喂入辊设置在不同水平面且平行排列。设置多个第二导丝辊及相应的喂入辊,可以增加单个纺丝位的产能,例如纤维的根数增加,从而增加产品的产量。Referring to FIG. 4, the second godet roller 2 is two, and the plurality of second godet rollers 2 are disposed in parallel above the first godet roller 1, and two feeds are provided below each of the second godet rollers 2. Into the roller 4, a winding device 5 is provided below each of the feeding rollers 4. The technical solution satisfies that the plurality of tows coming out from the same second godet roller have the same length of the fibers when entering different winding devices, and the degree of freedom is small, so that the physical properties are as uniform as possible, thereby improving the product quality of the fiber. In the embodiment of the invention, the feeding rollers can also be arranged at different horizontal planes and arranged in parallel. The provision of a plurality of second godet rolls and corresponding feed rolls can increase the capacity of a single spinning position, such as an increase in the number of fibers, thereby increasing the yield of the product.
本发明实施例提供的技术方案可实现效果和现有技术相比而言,现有技术丝束自由度大,在收卷过程中为了避免丝束缠绕到导丝辊上,需要使丝束具有较大的张力,而较大张力影响了如氨纶纤维等弹性纤维的纤度等物理特性。而 本发明实施例提供的技术方案,通过在第二导丝辊和收卷装置之间设置喂入辊,使得丝束的自由度小,这样丝束之间所受的张力适当减小也不易缠绕到导丝辊上;尤其对于氨纶纤维来说,其具有很大弹性,如果张力过大,纤维就被拉伸变细,影响其纤度,而采用本发明实施例提供的技术方案则可保证纤维品质,同时还可以在一个纺丝位放置更多收卷装置,以提高产能。The technical solution provided by the embodiment of the present invention can achieve the effect. Compared with the prior art, the prior art tow has a large degree of freedom, and in order to prevent the tow from being wound on the godet during the winding process, the tow has to be provided. Larger tension, while larger tension affects physical properties such as the fineness of elastic fibers such as spandex fibers. And According to the technical solution provided by the embodiment of the present invention, by providing a feeding roller between the second godet roller and the winding device, the degree of freedom of the tow is small, so that the tension between the tows is appropriately reduced and is not easily entangled. On the godet roller; especially for the spandex fiber, it has great elasticity. If the tension is too large, the fiber is stretched and thinned, affecting the fineness thereof, and the technical solution provided by the embodiment of the invention can ensure the fiber. Quality, and more winding devices can be placed in one spinning position to increase productivity.
可选的,所述喂入辊的线速度大于与其通过丝束连接的第二导丝辊的线速度、且喂入辊靠近与其通过丝束连接的收卷装置设置。该方案将喂入辊靠近与其通过丝束连接的收卷装置设置(即喂入辊距离与其通过丝束连接的第二导丝辊的距离,比喂入辊距离与其通过丝束连接的收卷装置的距离远),在此前提下可调整喂入辊的位置,使该收卷装置的卷轴的线速度与该第二导丝辊线速度之差小于第二设定阈值。Optionally, the feed roller has a linear velocity greater than the linear velocity of the second godet connected to the tow, and the feed roller is disposed adjacent to the winding device that is connected thereto by the tow. The solution sets the feed roller close to the winding device connected to it through the tow (ie, the distance of the feed roller from the second godet connected to the tow, the winding distance from the feed roller and its winding through the tow The distance of the device is far apart. Under this premise, the position of the feed roller can be adjusted such that the difference between the linear velocity of the reel of the winding device and the linear velocity of the second godet is less than a second set threshold.
一般一个纺丝位的纺速指的是收卷装置的卷轴的线速度。在现有技术生产时,第一导丝辊的线速度小于卷轴的线速度,第二导丝辊的线速度大于第一导丝辊线速度;实际减小丝张力是通过提高了第一导丝辊线速度来实现的,因为第一导丝辊速度的提高,务必要提高第二导丝辊线速度才能保证两辊之间的丝束有张力进行上油,但在现有技术中第二导丝辊线速度不能提太高,以防第二导丝辊后的自由段丝张力小而缠绕到导丝辊上。Generally, the spinning speed of one spinning position refers to the linear speed of the reel of the winding device. In the prior art production, the linear velocity of the first godet is less than the linear velocity of the reel, and the linear velocity of the second godet is greater than the linear velocity of the first godet; the actual reduction of the wire tension is achieved by the first guide The linear speed of the wire roller is realized. Because the speed of the first godet roller is increased, it is necessary to increase the linear velocity of the second godet roller to ensure that the tow between the two rollers has a tension for oiling, but in the prior art The linear speed of the two godet rolls cannot be raised too high to prevent the free length of the wire after the second godet roller from being small and wound onto the godet.
本发明实施例技术方案增加喂入辊后,可以使喂入辊线速度大于第二导丝辊线速度,使这段丝束有一定张力而不缠绕到导丝辊上,并且将喂入辊接近收卷装置设置,使两者之间的丝束自由段小,这样即便丝束张力小但其自由段也小,因此就不会出现丝束缠绕到喂入辊上的情形。After the feeding roller is added in the technical scheme of the embodiment of the present invention, the feeding roller linear velocity can be made larger than the second godet roller linear velocity, so that the tow has a certain tension without being wound onto the godet roller, and the feeding roller is to be fed. Close to the winding device, the free section of the tow is small, so that even if the tension of the tow is small, the free section is small, so that the tow is not wound around the feeding roller.
此外,第二设定阈值可尽量小,例如第二设定阈值为[0,0.15V1]中的任一值,其中V1表示第二导丝辊的线速度。该技术方案考虑喂入辊的设置位置、以及喂入辊和第二导丝辊、第一导丝辊的速度协调,其中,喂入辊的线速度V2大于与其通过丝束连接的第二导丝辊的线速度V1,使得喂入辊和第二导丝辊之间丝束具有较大的张力,由此保证丝束不会卷绕在第二导丝辊上;此外,将喂入辊靠近与其通过丝束连接的收卷装置设置,即喂入辊距离第二导丝辊远且距收卷装置近,使得收卷装置的线速度V3尽可能的逼近第二导丝辊的线速度V1,这样在第二导丝辊和喂入辊之间受较大张力被拉伸的丝束,传输到喂入辊和收卷装置的卷轴之间时,由于所受张力减少,被拉伸的丝束会适当收缩,由此该 方案减少了收卷后纤维的收卷后纤维的预牵伸力或残余牵伸力,由此保证了收卷后纤维纤度等物理特性。Further, the second set threshold may be as small as possible, for example, the second set threshold is any one of [0, 0.15 V1], where V1 represents the linear velocity of the second godet. The technical solution considers the position of the feeding roller, and the speed coordination of the feeding roller and the second godet roller and the first godet roller, wherein the feed roller has a linear velocity V2 greater than a second guide connected thereto through the tow. The linear velocity V1 of the wire roller causes the tow between the feeding roller and the second godet roller to have a large tension, thereby ensuring that the tow is not wound on the second godet; in addition, the feeding roller Proximity to the winding device connected to the tow thereof, that is, the feeding roller is far from the second godet roller and close to the winding device, so that the linear velocity V3 of the winding device approaches the linear velocity of the second godet as close as possible V1, such that the tow which is stretched between the second godet roller and the feed roller by a large tension is transferred between the feed roller and the reel of the winding device, and is stretched due to the reduced tension The tow will shrink properly, thus The solution reduces the pre-draw force or residual drafting force of the fibers after winding of the fibers after winding, thereby ensuring physical properties such as fiber fineness after winding.
上述技术方案中,对于一个第二导丝辊下方设置多个喂入辊的情形,多个喂入辊可平行设置,即:包括多个喂入辊在不同水平面平行设置;也包括多个喂入辊在同一水平面平行设置,以图1所示的一个第二导丝辊下方设置两个喂入辊的情形为例,两个喂入辊4可位于同一水平面平行设置,此设置设备制造简单统一,布置实用美观,成本低。In the above technical solution, for the case where a plurality of feeding rollers are disposed under one second godet roller, the plurality of feeding rollers may be arranged in parallel, that is, including a plurality of feeding rollers arranged in parallel in different horizontal planes; The infeed rolls are arranged in parallel on the same horizontal plane. For example, in the case where two feeding rolls are arranged under one second godet roller as shown in FIG. 1, the two feeding rolls 4 can be arranged in parallel on the same horizontal plane, and the setting device is simple to manufacture. Uniform, practical and beautiful layout, low cost.
上述技术方案中,对于一个喂入辊下方设置多个收卷装置的情形,多个收卷装置可平行设置,即:包括多个收卷装置在不同水平面平行设置;也包括多个收卷装置在同一水平面平行设置,以图3所示的一个喂入辊下方设置两个收卷装置的情形为例,两个收卷装置5可位于同一水平面平行设置,此设置设备制造简单统一,布置实用美观,成本低。In the above technical solution, in the case where a plurality of winding devices are disposed under one feeding roller, the plurality of winding devices may be arranged in parallel, that is, the plurality of winding devices are arranged in parallel in different horizontal planes; and the plurality of winding devices are also included. In the same horizontal plane, in the case where two winding devices are arranged under one feeding roller as shown in FIG. 3, the two winding devices 5 can be arranged in parallel on the same horizontal plane, and the installation device is simple and uniform in manufacturing, and is practically arranged. Beautiful and low cost.
上述技术方案中,可选的,丝束自甬道的出口分别到不同收卷装置的各路程之差均小于第一设定阈值。所述第一设定阈值越小越好,如第一设定阈值为[0,0.2L]之间的任一值,L为第一导丝辊和最近一个第二导丝辊之间的距离。该方案有利于保证自甬道的出口到收卷装置的丝束的长度相同或大致相同,进而有利于保证纤维的品质。In the above technical solution, optionally, the difference between the distances of the tows from the ramps to the different winding devices is less than the first set threshold. The smaller the first set threshold is, the better, as the first set threshold is any value between [0, 0.2L], and L is between the first godet and the nearest second godet. distance.
