■Aim of Collaboration Our company uses thermoplastic resins classified as nylon, polyester, and PVDF (polyvinylidene fluoride) as fishing line materials to meet the demands of anglers. As a manufacturer, we have honed our creative technological development capabilities and have engaged in various technological advancements since our founding. In recent years, we have heard that the importance of safety nets has increased due to a growing awareness of "safety management obligations." Additionally, I believe that considerations for hygiene have become necessary due to the impact of the COVID-19 pandemic. At our company, we can incorporate antibacterial agents, antiviral agents, and flame retardants into various materials to create fishing lines. Furthermore, we possess a diverse range of color masterbatches, allowing us to create unique safety nets that are one-of-a-kind in the world. We sincerely hope that our products can be of use to everyone.

Our company handles advanced technology that enables plasma treatment of various substances. We can perform plasma treatment on general chemical fibers such as polyamide (nylon), polyester, and polyethylene, as well as natural materials like cotton, super fibers such as ultra-high molecular weight polyethylene, and conductive fibers like steel wire and carbon fiber. It is possible to plasma-activate all types of gases, imparting properties such as wettability (hydrophilicity and hydrophobicity), adhesion, coating, and coloring (dyeing). Moreover, we can achieve high-density and uniform atmospheric pressure plasma treatment without compromising the physical properties of the target materials. 【Features】 ■ Continuous and rapid uniform plasma treatment of fibers (long items) is possible. ■ The properties of the fiber surface can be altered without flaking or dissolving in water. ■ Treatment is possible for a variety of materials. ■ Significantly improved water repellency, hydrophilicity durability, and adhesion strength. ■ High-density and uniform atmospheric pressure plasma treatment can be achieved without compromising the physical properties of the target materials. *For more details, please download the PDF or contact us.
