YKK List of Products and Services

This buckle differs from the type that requires both hands to combine the male part (plug) and the female part (socket), as it can be combined by simply pushing the female part onto the male part with one hand. It can be easily operated even in situations where one hand is occupied, such as in healthcare or sports applications. There are two types for securing the male part: one with holes for riveting or bolting, and another that can be directly sewn into the fabric. Both types are compatible with the female part, allowing for reconfiguration based on the application. 【Specifications】 - Size width options: 25mm, 38mm, 50mm - Available colors: white, black, gray, beige 【Material】 - Plug: Nylon - Socket: Polyacetal 【Caution】 Due to the properties of the resin material, if the combination is insufficient or if the push part is left pressed for an extended period, it may lead to deformation, reduced strength, or detachment (slipping out). Please insert it until you hear a "click" sound confirming the combination. After insertion, ensure that the combination is securely fixed before use. Additionally, to prevent deformation caused by the pushed part, always store it in a combined and fixed state.

The sewing loop is a product that consists of a ring section for threading flat cords and a sewing section that secures the ring to the fabric. The sewing section can be directly sewn with a sewing machine, which is expected to reduce the material cost of the flat cord previously needed for securing the ring. During use, the ring section stretches and contracts in response to the force applied to the curved part of the flat cord, enhancing the fit to the body. Additionally, the angle at which the ring section is attached allows for easier threading of the flat cord as it rises from the sewing surface. 【Specifications】 - Size options: 50mm - Available colors: white, black, gray, beige 【Material】 - Nylon 【Cautions】 - While it is possible to sew, there is a possibility of tearing or thread breakage depending on the thread gauge and pitch settings. We ask that customers conduct sewing prototype tests in advance.

Our AQUASEAL(R) zippers are widely used in applications requiring waterproofing, such as wetsuits, waterproof bags, and cooler bags. ◆ Background of Adoption in Tunnel Exhaust Ducts Exhaust ducts used in tunnel construction are extended by connecting them with zippers every 10 meters. However, due to frequent "air leaks" from the zippers, large fans or intermediate fans may be required. When the duct is long or the cross-sectional area of the tunnel is small, it becomes difficult to install intermediate fans. ◆ Key Points for Solving Challenges (How Fastening Helped) By adopting AQUASEAL(R) zippers at the connection points of the ducts, we successfully reduced air leakage to one-hundredth compared to conventional products. This led to the omission of intermediate fans and a reduction in electrical energy consumption. *For product details, please refer to the catalog available for download below as "PDF Download." *AQUASEAL is a registered trademark of YKK Corporation.

◆Background of Adoption for Underwater Construction Sheets The number of 'divers' performing work during underwater construction has been decreasing year by year. Additionally, the conditions at construction sites (such as underwater visibility, current speed, water temperature, etc.) impact the efficiency in terms of construction period, cost, and safety. There are challenges such as the removal of debris that occurs after the materials used underwater are removed, difficult tasks like deformation repairs, and high maintenance costs even when materials are reused. ◆Key Points for Problem Solving Traditionally, the assembly method of liner plates for temporary closure by divers was common, but the new method covers the outside of pre-assembled plates with a waterproof sheet utilizing the waterproof fastener AQUASEAL(R). This allows for segmented construction, significantly reducing the underwater work performed by divers. The reduction in underwater construction processes, improved economic efficiency through the reuse of plates, and enhanced safety by reducing the risk of decompression sickness have led to approximately a 20% reduction in construction costs and project duration.

Our AQUASEAL(R) zippers are widely used in applications requiring waterproofing, such as wetsuits, waterproof bags, and cooler bags. ◆ Background of Adoption in Care Bathtubs Bathing for those requiring nursing care poses challenges with standard bathtubs, such as "lifting and transporting them to the bathtub" and "the inability for those with paralysis to bathe." There are also risks associated with helping those requiring care enter and exit the bathtub. While there have been specialized devices that allow bathing while remaining in a wheelchair, their high cost means they are not accessible to all facilities, creating a demand for simpler installation and operation solutions. ◆ Key Points for Problem Solving (How the fastening products helped) By installing the waterproof zipper AQUASEAL(R) around the four sides of the care bathtub, a foldable design was achieved. The setup and storage can be done simply by opening and closing each part with a zipper, allowing one person to perform the task and successfully simplifying the existing equipment. *For product details, please refer to the catalog available for download below. *AQUASEAL is a registered trademark of YKK Corporation.

Our VISLON® zippers for fishing nets are available in sizes No.10 to No.30. For size No.30, which can be used when the zipper element comes off, we also provide repair elements. ◆ Background of Adoption for Fixed Nets Fixed nets are a fishing method where nets are set up in areas where fish migrate for a certain period to catch the guided fish. The fixed nets used for salmon and trout fishing are installed about 4 to 5 km upstream from the river mouth, extending 1 km in length and 20 to 50 m in width, and these nets are also equipped with zippers. ◆ Key Points for Problem Solving (How Fastening Helped) Traditionally, the ends of fishing nets were all secured with ropes, requiring the ropes to be removed and tied again during the catch, which posed a challenge for efficient harvesting methods. By instead installing VISLON® zippers for fishing nets, measuring approximately 10 to 20 m in length, we were able to improve work efficiency and enhance the safety of the workers. *For product details, please refer to the catalog available for download below. *VISLON is a registered trademark of YKK Corporation.

◆Background of Adoption for Construction Protective Netting Use ~The Burden of “Removing the Net” Work in Preparation for Strong Winds~ In construction sites, protective sheets known as "yousei sheets" are used to prevent paint splatter and other issues. When strong winds are expected, such as during typhoons, these sheets can catch the wind and potentially lead to scaffold collapse. As a result, the sheets must be removed each time strong winds are forecasted, creating a significant burden. ◆Key Points for Problem Solving (How Fastening Helped) Since the vents can be opened and closed with fasteners, it has become easy to create "holes" in the protective sheets to allow the wind to escape simply by opening the fasteners. Consequently, the work that previously required removing all protective sheets can now be done with only partial removal, successfully reducing the burden of the removal and installation work, leading to a decrease in labor costs. *For product details, please refer to the catalog available for download below.*
