背景技术Background technique
毛羽是衡量纱线质量的重要指标之一。纱线毛羽不仅影响机织、针织等后工序的生产效率,而且影响最终产品的外观质量,特别是高速无梭织机、高速经编机普遍应用的今天,大幅降低纱线毛羽,实现短纤纱表层结构的超光洁成形,具有十分重要的意义。Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of post-processes such as weaving and knitting, but also affects the appearance quality of the final product. Especially today, when high-speed shuttleless looms and high-speed warp knitting machines are widely used, yarn hairiness is greatly reduced, and short fiber The ultra-smooth and clean forming of the surface structure of the yarn is of great significance.
短纤维纱线主要有握持端纺纱和自由端纺纱,其中握持端纺纱以环锭纺纱为代表。环锭纺纱线毛羽产生于细纱加工工序,其机理是内外转移的纤维头端露出纱体之后,脱离钳口的握持作用,无法再次进入或包缠在纱体主干上,形成毛羽。自由端纺纱以转杯纺为代表,其成纱机理为纤维搭接层捻式加捻纺纱,纱线表层结构松弛,纤维头端易外露呈自由状,形成毛羽。纱线毛羽增长于络筒和整经工序,其根本原因在于:纱线表面毛羽多、结构松弛,在络筒、整经等纱线高速运行工序中,纱线经导纱部件、张力部件等机件,遭受激烈摩擦,致使纱体内部纤维头端严重抽拔游离于纱体表面,毛羽剧增、表层结构严重破坏。为了减少纱线毛羽,实现纱线顺利织造,纺织企业一般都对整经后纱线进行浆纱处理,贴附纱线毛羽、同时对纱线进行增强保伸、增加耐磨性。但整经通常采用片纱上浆,片纱上浆就会导致纱线相互粘连,需要湿、干分绞,纱线分绞时相互撕扯破坏纱体表面浆膜、产生二次毛羽。虽然单纱上浆可以解决分绞导致浆膜破损、二次毛羽的问题,但仍面临再次退浆、污染环境的问题。由此可见,消除纱线毛羽,增加纱线表层结构致密度应在上浆之前进行。Short fiber yarns mainly include grip-end spinning and free-end spinning, among which grip-end spinning is represented by ring spinning. Ring spinning yarn hairiness occurs in the spun yarn processing process. The mechanism is that after the end of the internally transferred fiber is exposed to the yarn body, it breaks away from the grip of the jaws and cannot re-enter or wrap around the yarn body, forming hairiness. Open-end spinning is represented by rotor spinning. Its yarn forming mechanism is twisted twist spinning with overlapping layers of fibers. The surface structure of the yarn is loose, and the fiber ends are easily exposed in a free shape, forming hairiness. Yarn hairiness increases in the winding and warping process. The root cause is that the surface of the yarn has many hairiness and loose structure. The mechanical parts are subjected to intense friction, causing the fiber head inside the yarn body to be pulled out and freed from the yarn body surface, the hairiness increases sharply, and the surface layer structure is seriously damaged. In order to reduce yarn hairiness and achieve smooth yarn weaving, textile enterprises generally sizing the warped yarn to attach yarn hairiness, and at the same time enhance the yarn elongation and increase wear resistance. However, warping usually uses sheet yarn sizing, which will cause the yarns to stick to each other, requiring wet and dry splitting. When the yarns are split, they will tear each other and destroy the size film on the surface of the yarn body, resulting in secondary hairiness. Although single yarn sizing can solve the problems of size film damage and secondary hairiness caused by split stranding, it still faces the problems of desizing again and polluting the environment. It can be seen that eliminating yarn hairiness and increasing the density of yarn surface structure should be done before sizing.
针对环锭细纱工序,国内外的学者做过大量的研究。通常采用的途径有两种,一种是采用常规方法优化普通环锭纺纱工艺,该方法只能一定程度上减少纱线毛羽,作用效果有限;另一种是采用新型纺纱技术或专用消除毛羽装置来消除毛羽,能大幅度降低环锭纱线毛羽。新型环锭纺纱技术或专用消除毛羽装置是目前环锭纺纱技术研究的热点。目前新型环锭纺纱技术代表是紧密纺纱技术,如美国知识产权局1984年12月18日公开的发明专利“Device for stretching,condensing and transporting a rove of fibers during aspinning operation”,专利号US 4488397;美国知识产权局2000年6月13日公开的发明专利“Device for condensing a drafted fiber strand”,专利号6073314;美国知识产权局2000年7月4日公开的发明专利“Arrangement for condensing a drafted fiberstrand”,专利号6082089;美国知识产权局2001年1月9日公开的发明专利“Transport beltfor transporting a fiber strand to be condensed”,专利号US 6170126B1;美国知识产权局2001年7月24日公开的发明专利“Arrangement and method for condensing adrafted fiber strand and method for making yarn thereform”,专利号US6263656B1;美国知识产权局2001年8月14 日公开的发明专利“Apparatus for condensinga drafted strand”,专利号US 6272834B1;美国知识产权局2001年5月29日公开的发明专利“Condensing zone for a spinning machine”,专利号US 6237317B1。上述紧密纺纱技术专利公案的核心原理都是针环锭纺纱过程,聚集纺纱三角区纤维须条,加强对纤维须条边缘纤维控制,有效降低纺纱过程纤维头端外露,降低纱线毛羽;但紧密纺消除纺纱三角区,纱体内部纤维内外转移不够,抱合力不足,外层仍有毛羽露出,纱体经受摩擦后毛羽仍旧剧增;特别是目前通过气流集聚的紧密纺纱技术,只对高支纱毛羽降低效果明显,对粗特纱线毛羽降低效果差。Scholars at home and abroad have done a lot of research on the ring spinning process. There are two ways usually used, one is to use conventional methods to optimize the ordinary ring spinning process, this method can only reduce yarn hairiness to a certain extent, the effect is limited; the other is to use new spinning technology or special elimination The hairiness device is used to eliminate the hairiness, which can greatly reduce the hairiness of the ring spinning yarn. The new ring spinning technology or the special hairiness elimination device is the current research focus of ring spinning technology. At present, the representative of new ring spinning technology is compact spinning technology, such as the invention patent "Device for stretching, condensing and transporting a rove of fibers during aspinning operation" published by the United States Intellectual Property Office on December 18, 1984, patent number US 4488397 The invention patent "Device for condensing a drafted fiber strand" disclosed by the United States Intellectual Property Office on June 13, 2000, patent No. 6073314; the invention patent "Arrangement for condensing a drafted fiber strand" disclosed by the United States Intellectual Property Office on July 4, 2000 ", Patent No. 6082089; the invention patent "Transport belt for transporting a fiber strand to be condensed" disclosed by the United States Intellectual Property Office on January 9, 2001, the patent No. US 6170126B1; the invention disclosed by the United States Intellectual Property Office on July 24, 2001 Patent "Arrangement and method for condensing adrafted fiber strand and method for making yarn thereform", patent number US6263656B1; the invention patent "Apparatus for condensinga drafted strand" published by the United States Intellectual Property Office on August 14, 2001, patent number US 6272834B1; The invention patent "Condensing zone for a spinning machine" published by the Intellectual Property Office on May 29, 2001, the patent number is US 6237317B1. The core principle of the above-mentioned compact spinning technology patent case is the needle ring spinning process, which gathers the fiber strands in the spinning triangle area, strengthens the control of the fibers at the edge of the fiber strands, effectively reduces the exposure of the fiber tip during the spinning process, and reduces the yarn loss. Hairiness; but compact spinning eliminates the spinning triangle area, insufficient internal and external transfer of fibers inside the yarn body, insufficient cohesion, and hairiness is still exposed in the outer layer, and the hairiness still increases sharply after the yarn body is subjected to friction; especially the compact spinning yarn that is currently concentrated by airflow Technology, the hairiness reduction effect of high-count yarns is obvious, and the hairiness reduction effect of coarse and special yarns is poor.
目前使用的专用降低毛羽装置是采用气流喷射形式,安装在前罗拉和导纱钩之间,利用气流的回转使已形成的毛羽贴伏在纱线表面,如美国知识产权局1979 年4月10日公开的发明专利“method and apparatus yarn treatment”,专利号 41481779、美国知识产权局1989年8月22日公开的发明专利“method and apparatus for modifying spuntextile yarn”,专利号5263311。这些研究主要差别在于由于气流喷射装置的不同导致纱线表面纤维受力方向不同,从而产生不同的卷绕效果而导致纱线毛羽消除效果的不同。但是由于这些装置的只能安装在加捻三角区后 (因加捻三角区中的纤维基本成散纤维状,喷射的气流会导致纤维运动混乱而断头),其气流吹拂对象为纱线和纱线表面毛羽,吹拂两对象的受气流转动效果不同,实现将毛羽以简单贴伏及松弛缠绕的形式留在纱线表面;在后道工序(如络筒)加工中,机件摩擦抽拔纱线表层结构的纤维,松弛贴服和缠绕的毛羽重新显露出来,达不到真正消除毛羽的效果。The special hairiness reduction device currently used is in the form of air jet, installed between the front roller and the yarn guide hook, and uses the rotation of the air flow to make the formed hairiness stick to the surface of the yarn, such as the United States Intellectual Property Office on April 10, 1979 The invention patent "method and apparatus for modifying spuntextile yarn" published on August 22, 1989 by the United States Intellectual Property Office, patent number 5263311. The main difference of these studies is that the direction of force on the fiber on the surface of the yarn is different due to the difference in the air injection device, resulting in different winding effects and resulting in different yarn hairiness elimination effects. But because these devices can only be installed behind the twisting triangular area (because the fibers in the twisting triangular area are basically in the form of loose fibers, the jet air flow will cause the fiber movement to be chaotic and end broken), the air blowing objects are yarn and The hairiness on the surface of the yarn and the blowing effect of the two objects are different, so that the hairiness can be left on the surface of the yarn in the form of simple fit and loose winding; in the subsequent process (such as winding), the mechanical parts are pulled out by friction The fibers of the surface structure of the yarn, the loose and entangled hairiness reappear, and the effect of truly eliminating the hairiness cannot be achieved.
针对络筒工序高速摩擦,造成纱线表面结构损伤,毛羽大量增长,强力下降,要求配套浆纱工序,增加上浆难度和上浆成本等问题,在络筒工序设置毛羽倒伏装置,抑制毛羽的发生,对后道工序生产和提高最终产品质量具有十分重要的意义。目前已经研究的减少成纱毛羽的方法主要集中在减少络筒纱线毛羽装置;虽然相关专利文献有很多,但采用的基本原理相同,即在纱线在络筒机上采用对前进中的纱线进行解捻-加捻方式,使纱线表面毛羽卷绕在纱线表面,达到减少毛羽的目的。代表性的专利文献有:欧洲专利号为EP 0 866014 A2,公开日1998 年09月23日,发明创造名称为Auto Winder,该申请公案采用络筒工艺流程中回转假捻盘的机械作用,使游离纤维沿纱线的捻向贴伏到纱身上来,以减少纱线毛羽;美国专利号为US 6 374 588 B1,公开日2002年04月23日,发明创造名称为Hairinesscontrolling device and winder,该申请公案采用络筒工艺流程中回转假捻盘的机械作用,使游离纤维沿纱线的捻向贴伏到纱体主干上来,以减少纱线毛羽;欧洲专利号为EP 1146 002 A2,公开日2001年10月17日,发明创造名称为Automatic winder and hairinesssuppressing device,该申请公案利用空气涡流管,通过旋转气流的力学作用,使毛羽重新包覆到纱身上,以减少毛羽,但从原理上分析,单凭气流的包缠作用,其包覆效果不好;欧洲专利号EP 1 013 803 A2,公开日2000年06月28日,发明创造名称为Hairinesssuppressing device for automatic winder,该申请公案同样使用空气涡流管,通过气流使纱线旋转,当旋转的纱线经过控制板(regulating plate)时,使纤维包缠在纱身上,以减少毛羽;中国专利号为ZL 99127507.1,公开日2000年07月05日,发明创造名称为自动络筒机的毛羽倒伏装置,该申请公案同样使用空气涡流管,通过气流使纱线旋转,不过该专利通过在装置两端加装控制器,以保证纱线沿自身轴线回转产生假捻效应,提高减少纱线毛羽的效率。除此之外,中国专利号为ZL 200710052991.8,公开日2008年01月23日,发明创造名称为一种减少成纱毛羽的方法,该申请公案提供一种采用假捻熨烫的方式,对络筒及针织过程的纱线进行在线贴附和包缠纱线毛羽,极少部分毛羽卷入纱体,实现络筒或针织过程中抑制纱线毛羽增长的目。上述减少纱线表面毛羽的方法和装置,共同点在于借助涡流吹拂或机械旋转等形式,对运行纱线实施先少量解捻纱体、包缠部分毛羽进入纱体,再加捻纱体恢复原状进一步缠绕毛羽,缠绕随机性致使毛羽多以倒伏、散乱包缠在纱干上;另外毛羽在倒伏、散乱包缠过程中,未得到积极有效地握持作用,毛羽倒伏、散乱包缠结构松弛,纱线表层致密化程度没有改善,降低的毛羽经受摩擦易于再次反弹;同时毛羽散乱缠绕到纱体时,因纤维聚集,降低毛羽后的纱线粗节、棉结等纱疵大幅增加。In view of the high-speed friction in the winding process, which causes damage to the surface structure of the yarn, a large increase in hairiness, and a decrease in strength, it requires a matching sizing process, which increases the difficulty of sizing and the cost of sizing. A hairiness lodging device is installed in the winding process to suppress the occurrence of hairiness. It is of great significance to the production of the subsequent process and the improvement of the quality of the final product. The methods of reducing yarn hairiness that have been studied so far are mainly focused on reducing the hairiness device of the winding yarn; although there are many related patent documents, the basic principle used is the same, that is, the yarn in the winding machine is used to control the yarn in progress. The untwisting-twisting method is used to make the hairiness on the surface of the yarn wrap around the surface of the yarn to reduce the hairiness. Representative patent documents include: European Patent No. EP 0 866014 A2, published on September 23, 1998, and the name of the invention is Auto Winder. The free fiber is attached to the yarn body along the twist direction of the yarn to reduce the hairiness of the yarn; U.S. Patent No. US 6 374 588 B1, published on April 23, 2002, the invention and creation name is Hairiness controlling device and winder, the The application uses the mechanical action of the rotating false twist disc in the winding process, so that the free fibers are attached to the main body of the yarn along the twist direction of the yarn, so as to reduce the hairiness of the yarn; the European patent number is EP 1146 002 A2, the publication date On October 17, 2001, the name of the invention was Automatic winder and hairiness suppressing device. The application used the air vortex tube to re-wrap the hairiness on the yarn body through the mechanical action of the rotating airflow to reduce the hairiness. However, from the principle analysis , the enveloping effect of the airflow alone is not good; European Patent No. EP 1 013 803 A2, published on June 28, 2000, the invention name is Hairiness suppressing device for automatic winder, and the application also uses air The vortex tube rotates the yarn through the airflow, and when the rotating yarn passes through the regulating plate, the fiber is wrapped around the yarn body to reduce hairiness; Chinese patent number is ZL 99127507.1, published on July 5, 2000 Invented and created a hairiness lodging device called an automatic winder on 12th, the application also uses an air vortex tube to rotate the yarn through the air flow, but the patent installs controllers at both ends of the device to ensure that the yarn moves along itself. Axis rotation produces false twist effect, improving the efficiency of reducing yarn hairiness. In addition, the Chinese patent number is ZL 200710052991.8, and the publication date was January 23, 2008. The name of the invention is a method for reducing yarn hairiness. The yarn in the bobbin and knitting process is attached and wrapped yarn hairiness online, and a very small part of the hairiness is involved in the yarn body, so as to achieve the purpose of inhibiting the growth of yarn hairiness in the winding or knitting process. The above-mentioned methods and devices for reducing hairiness on the surface of the yarn have in common that by means of eddy current blowing or mechanical rotation, a small amount of untwisted yarn body is carried out on the running yarn, and some hairiness of the wrapped yarn enters the yarn body, and then the twisted yarn body is restored to its original state. The hairiness is further entangled, and the randomness of the winding causes the hairiness to be lodging and scattered on the yarn shaft; in addition, the hairiness is not actively and effectively held during the process of lodging and scattered entanglement, and the hairiness is lodging and the loose entanglement structure is loose. The degree of densification of the yarn surface is not improved, and the reduced hairiness is easy to rebound again after being subjected to friction; at the same time, when the hairiness is scattered and wound onto the yarn body, due to fiber aggregation, yarn defects such as thick places and neps in the yarn after reducing the hairiness increase greatly.
由此可见上述对络筒、整经、针织等纱线使用过程的纱线毛羽控制,现有方法共同点在于:在非积极握持毛羽头端的情况下,对纱线进行假捻或气流吹拂包缠,将伸出纱线表面的绝大部分毛羽以较松散形式卷绕、贴服在纱线面,毛羽纤维和纱线本体之间无法形成致密的结构联系,仅仅从视觉上实现毛羽减少;针对采用解捻-加捻的形式,贴附毛羽过程中,纱线局部捻度受到动态转移和重新分布,出现捻度较弱部位,易受纱线张力拉伸而恶化纱体主干均匀度。更关键的是,在后道工序中,随着纱线受到机件的磨擦,这些松弛卷绕、贴服在纱线表面的纤维很容易再次伸出纱线表面形成毛羽,对纱线后道工序的加工和最终产品的质量没有本质改善。It can be seen that the above-mentioned yarn hairiness control for the yarn use process such as winding, warping, knitting, etc., the common point of the existing methods is: false twisting or air blowing of the yarn under the condition of not actively holding the head end of the hairiness Wrapping, winding most of the hairiness protruding from the surface of the yarn in a loose form, and sticking to the yarn surface, the dense structural connection between the hairiness fiber and the yarn body cannot be formed, and the reduction of hairiness can only be achieved visually ; For the form of untwisting-twisting, during the process of attaching hairiness, the local twist of the yarn is dynamically transferred and redistributed, and the weaker twist appears, which is easily stretched by the yarn tension and deteriorates the evenness of the main body of the yarn. More importantly, in the subsequent process, as the yarn is rubbed by the machine parts, the fibers that are loosely wound and attached to the surface of the yarn are easy to protrude out of the surface of the yarn again to form hairiness, which is harmful to the yarn in the subsequent process. There is no substantial improvement in the processing of the process and the quality of the final product.
针对上述问题,中国专利号为ZL 201410204503.0,公开日2014年05月15 日,发明创造名称为一种积极握持旋转式改善纱线表层结构的方法,该申请公案提供一种采用负压吸附握持纱线表层毛羽,同时将握持毛羽旋转地紧密缠绕在纱线主干上;然而由于锥形握持面沿整个一周上全部具有负压握持作用,对较为粗硬、同时毛羽与纱体主干连接处比较脆弱易断的纱线毛羽,处理过程中往往因断裂的粗硬纤维堵塞锥形握持面上的网孔,再加上车间飞花贴服在网孔上,致使锥形握持面对纱线表面的握持作用大大减弱、甚至丧失,不能满足持续有效的握持包缠纱线表面毛羽的作用;另一方面,毛羽缠绕到纱体时,在缠绕处以垂直于纱线主干的方式高速旋转缠绕到纱干上,不仅对毛羽未能以较大螺距缠绕在纱体上、无法改善纱线强力,而且纱线毛羽往往因在纱体上的聚集缠绕,造成纱线粗节、棉结等纱疵大幅增加,对应的织物外观疵点也增多;特别是锥形握持面旋转一周,只能将毛羽在纱体上缠绕一圈,如果提高毛羽包缠效率,需要大幅提升锥形握持面旋转速度,增加能耗和旋转部件磨损,尚不能实现高速、高效缠绕毛羽的纱线超光洁处理技术目的。中国专利号为ZL201510700297.7,公开日2015年 10月26日,发明创造名称为一种多毛羽纱线的超光洁整经方法,提供了一种对整经过程中的多毛羽纱线进行超光洁处理的方法;中国专利号为ZL201510700297.7,公开日2015年10月26日,发明创造名称为一种多毛羽纱线的超光洁纬编针织方法,提供一种对纬编针织过程中的多毛羽纱线进行超光洁处理的方法;中国专利号为ZL 201510700161.6,开日2015年10月26日,发明创造名称为一种定向伸展协同柔化缠绕纱线毛羽的方法,提供了一种定向伸展式有序包缠、避免毛羽包缠形成纱疵的多毛羽纱线后处理方法,可用于细纱、络筒、整经、针织等工序。虽然上述三个申请公案能够较为高速、高效地缠绕纱线毛羽以实现多毛羽纱线的超光洁处理,但是该三个申请公案所涉及的涡旋包缠装置,采用整体式涡流管状结构,高速运行的纱线表面浮游毛羽、棉结等易脱落堵塞入纱通道,造成断头率较高;当纱线断头时,纱线只能用细丝贯穿式牵引法,将纱线引导通过涡旋包缠装置后在进行接头,接头穿纱麻烦、效率低,维护不便、产业推广受限;这种情况下采用半敞开式涡流室设计,又导致涡流强度差、毛羽包缠紧度和效率低、无法实现高效高速包缠,只用于速度较低的环锭纺纱、低速倒筒等工序设备上,不能适用高速络纺织机上;并且涡旋包缠装置仅起到单次涡流包缠功能,对个别未受到充分包缠的外露毛羽无法进行二次包缠,处理后的纱线超光洁度有待进一步提升。In view of the above problems, the Chinese patent number is ZL 201410204503.0, and the publication date was May 15, 2014. The name of the invention is a method for actively holding and rotating the surface layer of the yarn. Hold the surface hairiness of the yarn, and at the same time tightly wrap the holding hairiness on the yarn trunk; however, because the tapered holding surface has a negative pressure holding effect along the entire circumference, it is relatively rough, and the hairiness and the yarn body at the same time The yarn hairiness at the trunk connection is relatively fragile and easy to break. During the processing, the mesh holes on the tapered holding surface are often blocked by broken thick and hard fibers, and the flying flowers in the workshop are attached to the mesh holes, resulting in a tapered grip. The holding effect facing the yarn surface is greatly weakened or even lost, which cannot satisfy the continuous and effective function of holding and wrapping the hairiness on the surface of the yarn; The way of high-speed rotation on the yarn stem, not only the hairiness cannot be wound on the yarn body with a large pitch, and the yarn strength cannot be improved, but also the yarn hairiness is often gathered and wound on the yarn body, resulting in thick spots in the yarn Yarn defects such as neps and neps have increased significantly, and the corresponding fabric appearance defects have also increased; especially when the tapered holding surface rotates once, the hairiness can only be wound around the yarn body once. The rotation speed of the shaped holding surface increases the energy consumption and the wear of the rotating parts, and the technical purpose of super-clean treatment of yarns with high-speed and high-efficiency winding hairiness cannot be achieved yet. The Chinese patent number is ZL201510700297.7, and the publication date was October 26, 2015. The invention name is an ultra-smooth and clean warping method for hairy yarns. The method of bright and clean treatment; the Chinese patent number is ZL201510700297.7, and the publication date was October 26, 2015. The invention and creation name is an ultra-clean weft knitting method for a multi-hairy yarn, which provides a method for weft knitting in the weft knitting process. A method for ultra-clean treatment of hairy yarns; Chinese patent number is ZL 201510700161.6, opened on October 26, 2015, and the name of the invention is a method for directional stretching and synergistically softening the hairiness of winding yarns, which provides a directional The post-treatment method for hairy yarns is stretching and orderly wrapping to avoid yarn defects caused by hairiness wrapping, which can be used in spinning, winding, warping, knitting and other processes. Although the above three applications can wrap yarn hairiness relatively high-speed and efficiently to achieve ultra-smooth treatment of hairy yarns, the vortex wrapping devices involved in the three applications adopt an integral vortex tubular structure, high-speed The floating hairiness and neps on the surface of the running yarn are easy to fall off and block the yarn-entry channel, resulting in a high end-breakage rate; After spinning the wrapping device, the joint is performed, which is troublesome for yarn threading, low efficiency, inconvenient maintenance, and limited industrial promotion; in this case, the semi-open vortex chamber design is used, which leads to poor eddy current intensity, hairiness wrapping tightness and efficiency Low, unable to achieve high-efficiency and high-speed wrapping, only used for low-speed ring spinning, low-speed rewinding and other process equipment, not suitable for high-speed webbing machines; and the vortex wrapping device only plays a single vortex wrapping function, the secondary wrapping cannot be performed on individual exposed hairs that have not been fully wrapped, and the super smoothness of the treated yarn needs to be further improved.
涡流纺纱机采用涡旋气流包缠纤维成纱,是目前生产高光洁短纤纱的最有效技术,技术设备自动化程度高、成纱速度快,纺纱速度高达450m/min;技术代表为瑞士立达公司的MJS型、日本村田MVS型涡流纺纱机,涡流纺纱原理为:涡流纺纱器由输纤管道、纤维流引导器、外管和静止锭(又称芯管)等部分组成;外管上开有3或4只切向的进风口,下端与鼓风机相连,风机不断地从管中抽取空气,外面的空气沿进风口进入涡流管内,产生旋涡状的气流;纤维条由给棉罗拉喂入涡流纺纱机的牵伸系统,经过牵伸输出的纤维须条借助气流作用,从输棉管道高速喂入涡流纺纱器内;当旋转向上的气流到达芯管时,与由输纤管道输送、经纤维流引导器引导进入的纤维汇合,沿涡流管内壁形成一个凝聚纤维环,稳定地围绕静止锭轴线,高速回转,将纤维进行包缠加捻成纱。由于涡流纺纺纱属于包缠成纱,纱线表层结构致密缠绕,表面光洁。但是由于涡流纱线内部纤维内外转移不够,纱体纤维抱合力差,光洁的纱表无法弥补纱体结构不足,因此涡流纱强度低、纱体稳定性和耐磨性差。因此涡流纺纱机多用于加工和生产抱合力较大、非常柔软的黏胶纤维纺纱,不适合高刚度麻类纤维、高回弹高卷曲毛类纤维等难纺纤维成纱,更不具备生产和加工出高强高光洁的常规细特纱线的能力。因此如何利用涡流包缠原理,高速高效地超光洁增强加工出高刚度麻类纤维、高回弹高卷曲毛类纤维等难纺纤维高支纱线,是亟待解决的纱线加工技术瓶颈问题。The vortex spinning machine adopts the vortex airflow to wrap the fiber into yarn, which is the most effective technology for producing high-quality spun yarn at present. The technical equipment has a high degree of automation, and the yarn forming speed is fast, and the spinning speed is as high as 450m/min; the technical representative is Switzerland Rieter's MJS type and Japan Murata MVS type vortex spinning machine, the vortex spinning principle is: the vortex spinning device is composed of a fiber delivery pipe, a fiber flow guide, an outer tube and a stationary spindle (also known as a core tube) and other parts. There are 3 or 4 tangential air inlets on the outer tube, the lower end is connected with the blower, the fan continuously extracts air from the tube, and the outside air enters the vortex tube along the air inlet to generate a vortex-shaped air flow; Cotton rollers are fed into the drafting system of the vortex spinning machine, and the fiber strands output after drafting are fed into the vortex spinning device at a high speed from the cotton delivery pipeline by the action of the air flow; The fibers transported by the fiber delivery pipe and guided by the fiber flow guide converge, forming a condensed fiber ring along the inner wall of the vortex tube, stably surrounding the axis of the stationary spindle, rotating at high speed, wrapping and twisting the fibers into yarn. Since the vortex spinning belongs to the wrapped yarn, the surface structure of the yarn is densely wound and the surface is smooth. However, due to the insufficient internal and external transfer of fibers in the vortex yarn, the fiber cohesion of the yarn body is poor, and the smooth yarn surface cannot make up for the insufficient structure of the yarn body, so the strength of the eddy current yarn is low, and the yarn body stability and wear resistance are poor. Therefore, the vortex spinning machine is mostly used for processing and producing viscose fiber spinning with large cohesion force and very softness. It is not suitable for spinning fibers such as high-rigidity hemp fibers, high-resilience and high-curl wool fibers, etc. The ability to produce and process high-strength, high-gloss conventional fine yarns. Therefore, how to use the principle of eddy current wrapping, high-speed and efficient ultra-clean enhancement processing to produce high-count yarns of difficult-to-spin fibers such as high-stiffness hemp fibers, high-resilience and high-curl wool fibers, is a bottleneck problem in yarn processing technology that needs to be solved urgently.

Pneumatic device, when the yarn breaks, the pneumatic device drives the push-pull rod 20 to move the moving petal body of the vortex device to the direction away from the static petal body of the vortex device. It is convenient for yarn jointing and cleaning of the yarn channel inside the device, and effectively solves the technical problem of "the existing eddy current wrapping device is difficult to break the yarn joint, and the industrial promotion is limited"; when the yarn runs continuously, under the action of the push-pull rod 20, The static valve body of the vortex device and the movable valve body of the vortex device are closed to efficiently restrict the airflow in the vortex chamber, and the airflow utilization rate is high, avoiding the technical problem of "semi-open joints, but low eddy current utilization rate". Each air outlet pipe 8 is connected in parallel with the directional air jet pipe 18, and the end face of the air outlet 19 of the directional air jet pipe 18 is parallel to the central axis of the yarn inlet channel of the yarn guide tube, and the yarn surface hairiness is stretched directionally, so as to avoid random dispersion and entanglement of the hairiness, and remove Impurities on the yarn surface and floating hairiness eliminate the unfavorable factors of "impurities and fibers accumulating inside the device and blocking the yarn channel, causing end breakage and reducing efficiency, etc.", improving application production efficiency and stability; each intake pipe 5 is connected in parallel To the air compressor, so that each vortex chamber injects a high-pressure jet with a pressure of 4-8MPa. The high-pressure jet is ordinary air or high-temperature hot and humid steam. The temperature of the hot and humid steam is 100-180°C. The higher the temperature, the higher the vitrification or softening point temperature, the higher the temperature of the hot and humid steam, which can soften and wrap the hairiness on the surface of the yarn and improve the wrapping effect; the high-pressure jet generates eddy current in each vortex chamber, and the yarn passes through each Under the action of the vortex gas in a closed vortex chamber, the hairiness on the surface of the multi-hairy yarn is tightly wrapped by multiple superimposition and repeated strengthening, which realizes the ultra-clean treatment of the yarn and breaks through the "existing device that only uses a single vortex for airflow wrapping."

It can only be applied to low-speed ring spinning, low-speed rewinding and other process equipment, and cannot be applied to textiles with different speeds of yarn in various textile processes. The technical bottleneck of "on-machine"; after the yarn surface hairiness is ultra-clean and wrapped, the fiber utilization rate of the yarn body is improved, and the yarn strength is enhanced, which solves the problem of "the high smoothness of the fiber cannot be achieved by vortex spinning, and the synergistic enhancement of the yarn body structure is formed and the fiber is suitable for spinning." And yarn varieties are limited" and other technical problems. According to actual needs, the valve-closed device can also be processed into a monolithic device.
