Esback N (alkaline) / NN MICRO HOLE CLEANER (neutral) is a product developed as a dedicated cleaning agent for synthetic fiber spinning nozzles, based on years of accumulated knowledge and experience. Traditionally, nozzle cleaning has been performed using salt baths, TEG, etc., but due to changes in fillers (additives) in polymers, residues have been observed inside the porous fine-hole nozzles, leading to a shift in the approach to cleaning. By introducing Esback N into the cleaning process, we can meet the demands for effective cleaning. 【Features】 ○ Strong penetration power ○ Efficiently removes resin, fillers, carbon, etc., adhered to the inside of the nozzle ○ Esback N is alkaline and does not cause hydrogen embrittlement on iron and stainless steel ○ Does not contain harmful cyanides, chromium, or phenols For more details, please contact us or download the catalog.

The non-woven fabric nozzle and non-woven fabric device "Meltblown Spunbond" is a method for producing non-woven fabric in a single step from raw resin. Melted thermoplastic plastic resin is extruded from a die installed after the extruder and blown onto a net conveyor or collection screen with a high-speed, high-temperature airflow, creating a self-adhesive web. On the other hand, spunbond involves heating and melting low melting point resin chips, such as polypropylene, and directly spinning them by extruding through a nozzle. The endless long fibers that are extruded are layered on top of each other on a belt conveyor to form a web. For more details, please download the catalog.

The non-woven fabric nozzle and non-woven fabric device "Spunlace" is a method for producing non-woven fabric by injecting high-pressure water flow into a fiber web to entangle the constituent fibers. By appropriately selecting the pressure and frequency of the high-pressure water flow ejected from the nozzle during the entanglement process, as well as the composition of the raw materials of the fiber web, a wide variety of patterns can be imparted to the non-woven fabric.

The "melt nozzle" for synthetic fiber spinning is used when converting thermoplastic polymers (polymeric materials) into fibers. The polymer, which has become highly fluid due to high heat, is extruded under pressure through small holes, and while being pulled, it is cooled to form yarn. Compared to other spinning methods, the spinning speed is fast and productivity is high. It is used for spinning materials such as polyester and nylon. By changing the shape of the nozzle holes, fibers with various cross-sections can be produced. For more details, please download the catalog.

The "dry nozzle" for synthetic fiber spinning is a method that involves dissolving a polymer (high molecular material) in a solvent to create a polymer solution, which is then extruded through a porous nozzle. This solution is dried with hot air, causing the solvent to evaporate and forming fiber filaments. It is used for materials such as acetate, spandex, and acrylic. The dry spinning nozzle requires a higher level of precision compared to other nozzles. In the case of round hole nozzles, the diameter and length of the holes are important. For shaped hole nozzles, the edge width, edge length, and configuration angle, as well as the angle and cross-sectional shape of the inlet hole, are crucial. Additionally, the share of acetate is the highest in the world. For more details, please download the catalog.

The "wet nozzle" for synthetic fiber spinning is a method where polymers (high molecular materials) are extruded from the nozzle to discharge the spinning dope into a coagulation liquid, causing solidification or regeneration through contact with the coagulation liquid, and then separating from the coagulation liquid to form fibers. It is used for rayon, vinylon, acrylic, and others. For more details, please download the catalog.

Carbon fibers (dry and wet nozzle) have superior strength and elasticity compared to carbon fibers produced by the wet spinning method, making them widely used as acrylic precursors for the manufacture of high-strength and high-elasticity carbon fibers. They are utilized in a wide range of applications, including structural materials for aerospace and industrial fields, as well as in sports and leisure sectors. The dry and wet spinning method involves directing the polymer ejected from the nozzle into a gas stream and then immediately guiding it into a coagulation bath to solidify. The nozzle size tends to increase depending on the spinning conditions, and using precious metals for the material can lead to increased costs, so relatively inexpensive stainless steel is commonly used.

The wet spinning nozzle for synthetic fibers is classified into PAN (polyacrylonitrile) type and pitch (such as coal tar) type based on the raw materials. About 90% of the carbon fiber market is PAN type. PAN-based carbon fibers are obtained by carbonizing PAN precursors (polyacrylonitrile fibers) and possess high strength and high modulus properties. The wet spinning method involves fiber formation from the spinning dope in a coagulation liquid, allowing for a higher number of holes per unit area of the nozzle compared to dry and wet spinning methods.
