A flap-closing device for super-clean treatment of yarn

technical field

The utility model relates to a flap closing device for super-clean treatment of yarns, which belongs to the technical field of textile processing.

Background technique

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.

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.

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.

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.

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.

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.

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.

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.
