A super-clean warping method for hairy yarn

technical field

The invention relates to an ultra-clean warping method for hairy yarns, belonging to the technical field of textile processing.

technical background

Warping technology is a process in which a certain number of warp yarns are wound parallel to the warp beam or weaving beam with a suitable and uniform tension according to the specified length and width of the process design. The warping process makes the warp package change from a bobbin to a warp beam or a weaving beam. If the warp beam is made, it will be formed into a weaving beam through the sizing process; if it is a weaving beam, it will be provided to the warp drawing The process directly prepares for the warp system that constitutes the fabric. The warping process is mainly to arrange the yarn better, to ensure that the yarn has no skein, no broken end, no yarn wave, no flying flower, no thread-back, and no wrong branch. After finishing, the yarn is required to be evenly arranged and the winding density is uniform. The above-mentioned problems in the warping process are mostly caused by too much and too long hairiness on the surface of the yarn: too much hairiness of the yarn, increased warping friction, easy wear and tear of the yarn and broken ends; too long yarn hairiness, hairiness It is easy to wear and fall off or become entangled with each other in the form of neps, forming flying flowers and being brought into the warp beam package; in addition, the yarn hairiness is too much and too long, and the yarns are easily entangled and kinked together. At the same time, the warping yarn has too much hairiness, and when the subsequent warp beam package is sizing the subsequent sheet yarn, the yarn unwound from the warp beam package is sized in a way of hairiness entanglement, and is carried out through wet split and dry split rods. When splitting, the problem of secondary hairiness is serious. After sizing, thick, hard and strong secondary hairiness will be generated, which will cause more serious damage to loom heddles, steel buckles and other mechanisms, and reduce weaving efficiency and product quality.

For the above-mentioned warping and the technical problems caused by warping, the current solutions include: improving the warping process and technology, improving the hairiness of warping yarns, and adopting single-yarn sizing technology. Although the single-yarn sizing technology can avoid the technical defect of secondary hairiness caused by yarn splitting during the yarn sizing process, the current single-yarn sizing technology has low efficiency and is only suitable for small sample processing in laboratories and college laboratories. High-speed, efficient conditions for mass industrial production. The warping yarn is generally package yarn, that is, the package yarn formed by the winding process; the modern winding process requires high speed and automation, and the automatic winding speed is as high as 1200 m/min, which leads to serious escalation of yarn wear during winding. It shows that the total amount of yarn hairiness increases by 3-5 times after the bobbin is automatically wound, and the hairiness of 4 mm and above increases even more. Problems with excessive increase in thread hairiness. Although the problem of bobbin hairiness can be solved by singeing, singeing will cause loss and waste of raw materials. Under the current situation of rising raw material costs, factories generally do not use it easily.

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 is required to increase the singeing process, increase the difficulty of sizing, and increase 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 warping 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 of the winding yarn; although there are many related patent documents, the basic principle used is the same, that is, only the yarn in progress is used on the winding machine. The thread is untwisted-twisted, so that the hairiness on the surface of the yarn is wound on the surface of the yarn, so as to reduce the hairiness. Representative patent documents include: European Patent No. EP0866014A2, published on September 23, 1998, and the name of the invention is AutoWinder. The twist direction of the thread is attached to the yarn body to reduce yarn hairiness; US Patent No. US6374588B1, published on April 23, 2002, the invention name is Hairinesscontrollingdeviceandwinder, and the application uses rotary false twist in the winding process. The mechanical action of the disk makes the free fiber stick to the main body of the yarn along the twist direction of the yarn to reduce the hairiness of the yarn; the European patent number is EP1146002A2, the publication date was October 17, 2001, and the invention name is Automaticwinderandhairinesssuppressingdevice. The application uses 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 a theoretical analysis, the wrapping effect of the airflow alone is not good; the European patent No. EP1013803A2, published on June 28, 2000, the name of the invention is Hairiness suppressing device for automatic winder. This application also uses an air vortex tube to rotate the yarn through the air flow. When the rotating yarn passes through the regulating plate, the fiber package Wrapped on the yarn body to reduce hairiness; Chinese Patent No. ZL99127507.1, published on July 5, 2000, invented and created a hairiness lodging device called an automatic winder. The application also uses an air vortex tube to pass the airflow The yarn is rotated, but the patent installs controllers at both ends of the device to ensure that the yarn rotates along its own axis to produce a false twist effect and improve the efficiency of reducing yarn hairiness. In addition, the Chinese patent number is ZL200710052991.8, published on January 23, 2008, and the name of the invention is a method for reducing yarn hairiness. The application provides a method of ironing with false twist. The yarn in the winding and knitting process is attached and wrapped on-line, 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 yarn surface hairiness have in common that the yarn hairiness is laid down and rewrapped on the yarn stem through airflow or mechanical form. A large number of practices have shown that there are three major characteristics of this kind of lodging and rewrapped hairiness: The direction of the lodging and re-wrapping of the hairiness is opposite to the direction of the yarn movement, so that when the package yarn is unwound and warped in the warping process, the lodging and re-wrapping hairiness is in the same direction as the yarn, and it is very easy to be scraped out again and rebound During the entire process of hairiness lodging and re-wrapping, there is no active and effective holding effect, the hairiness is lodging, the re-wrapping structure is loose, and the densification degree of the yarn surface is not improved, but the reduced hairiness is easy to rebound again after being subjected to friction; at the same time When the hairiness is entangled in the yarn body, due to the accumulation of fibers, the yarn defects such as thick places and neps in the yarn after the reduction of hairiness increase greatly. In response to this problem, the Chinese patent number is ZL201410204503.0, and the publication date was May 15, 2014. The name of the invention is a method for actively holding and rotating the surface of the yarn to improve the surface structure. The application provides a method that uses negative pressure adsorption Hold the hairiness on the surface of the yarn, and at the same time tightly wrap the holding hairiness on the yarn trunk; practice has proved that this method can effectively reduce the hairiness on the surface of the yarn, but it still does not solve the problem that the direction of hairiness wrapping is opposite to the direction of yarn movement, and the hairiness Wrapping produces fiber aggregation, which leads to technical problems such as a substantial increase in yarn defects such as thick places and neps.

At present, there are mainly two ways to improve the warping process and technology: the first is to simply introduce the hairiness reduction technology and equipment of the above-mentioned winding process into the warping process; obviously, the introduction and grafting of this technology still have the above-mentioned hairiness Deadly problems such as winding direction, density, and accumulation of yarn defects. The second method is to optimize the warping process by reducing friction, eliminating static electricity, and uniform tension. The Chinese patent number is ZL201420172641.0. Static removal device, the application provides a spray device to eliminate static electricity generated by friction between fibers and fibers, and between fibers and mechanical parts during the warping process, causing problems such as increased hairiness, dust on the yarn, and poor formation of the warping package; China The patent number is ZL201420735671.8, the publication date is December 01, 2014. The name of the invention is a friction-reducing yarn guide for warping machines. The application provides a sheet-shaped rotatable yarn guide, which can Reduce the friction between the yarn and reduce the mass production of warping hairiness from the mechanism of anti-friction; Gray, warping package forming problems, etc.; U.S. Patent No. US4903914, published on February 27, 1990, the name of the invention is Warpingyarnaccumulator. The regulator can automatically adjust the warp yarn tension to make the tension uniform. Obviously, the second method only optimizes the warping process from reducing friction, uniform tension, and eliminating static electricity, and the effect of improving yarn warping is very limited; obviously, these methods cannot arrange hairy yarn raw materials into smooth warp yarns.

Comparing the above technical background, it can be seen that the yarn hairiness reduction device is directly installed in the warping process, which can avoid more hairiness due to high-speed friction during the warping process of the hairy yarn at a speed of 400-1200 m/min. rebound. However, the existing mechanical and air-flow online yarn hairiness reduction technologies still have fatal technical problems: the smooth yarn obtained by winding the hairiness to the yarn body has a large rebound range of the hairiness during subsequent unwinding processing; during the hairiness reduction process, there are The accumulation of fibers leads to a substantial increase in yarn defects such as thick places and neps. This shows that above-mentioned technology still can't realize the ultra-clean warping of multi-hairiness bobbin raw material.
