Who Invented Zippers?

Early Attempts at Zipper-Like Devices

Since the 1800s, inventors have been trying to find a fastener that is similar to the zipper. Elias Howe first designed a device called the "Automatic Continuous Clothing Closure" in 1851, but it was never produced. Whitcomb Judson invented and patented a device in 1890 called the "Clasp Locker," which was used primarily on shoes and boots. However, this design was difficult to open and close and was not successful in the market.

The Modern Zipper

In 1913, Gideon Sundback, a Swedish-American engineer, invented the modern zipper as we know it today. Sundback improved upon Judson's design by increasing the number of fastening elements and making them smaller, which allowed for a more secure and efficient fastening mechanism. Sundback's design used metal teeth with a slider, which either joined or separated the teeth when moved. He called his invention the "Separable Fastener" and was granted a patent for it in 1917.

Zipper Adoption and Evolution

Initially, the zipper was used for boots and tobacco pouches due to their durability and ability to keep contents secure and dry. However, in the 1920s, the fashion industry began to adopt the zipper for clothing, revolutionizing the way people dressed. The convenience and versatility of the zipper allowed for new clothing designs and improved the ease of dressing. In the 1930s, zippers continued to evolve with the introduction of plastic teeth, which reduced the cost and weight of the fastener. The invention of the invisible zipper in the 1940s allowed for a sleeker and more seamless look in clothing. The improvements in the zipper continued into the 21st century, with advancements in design, durability, and ease of use. In conclusion, the invention of the zipper by Gideon Sundback revolutionized the way people dress and secured his place in history. From its humble beginnings in boots and tobacco pouches to being a staple in clothing and everyday products, the zipper has undergone significant improvements and evolution over time. Its convenience and versatility have made it an integral part of our daily lives.Who developed the first tractor in history? Learn the interesting story behind it!

Who Invented Zippers?

The modern zipper is widely considered one of the most convenient and ingenious inventions of the 20th century, but few people know who the original inventor was.

The First Zipper

The first prototype zipper was created by a young Chicago-born inventor named Whitcomb Judson in 1891. The invention was originally called the "Clasp Locker" and was intended to be used as a fastener for shoes.

The Clasp Locker consisted of a series of hooks and loops that clasped together, but it was too complicated and expensive to manufacture. Judson eventually partnered with a businessman named Lewis Walker to found the Universal Fastener Company, which focused on developing simpler and more effective fasteners.

The Evolution of the Zipper

In 1913, Swedish-American engineer Gideon Sundback developed a new and improved version of the zipper. His design employed interlocking teeth made of metal with a slider that could be moved up and down to open and close the fastener.

The new-and-improved zipper was considered a major breakthrough in fastening technology, and Sundback's design is the basis for the modern zipper we use today. Sundback's design was marketed under the name "Hookless #2" and became an instant success.

How Do Zippers Work?

Zippers consist of two interlocking strips of teeth or coils, a slider that moves along the strips, and a pull tab used to open or close the zipper. The slider has prongs that mesh the teeth on both sides of the zipper's strips together and a spring in the rear that allows the slider to move smoothly up and down the zipper.

Zippers' Basic Anatomy

Understanding a zipper's basic anatomy is crucial for learning how zippers work. The two interlocking strips of teeth or coils are often referred to as the "chain" or "elements." The slider is the component that glides up and down the elements, bringing the two sides of the chain together or pulling them apart. The pull tab is found on the end of the slider, and it is used to open or close the zipper.

Types of Zippers

There are various types of zippers, such as coil, metal, plastic, and invisible, each suited for different applications and materials. Coil zippers are composed of a continuous coil that is sewn onto the fabric and is often used in lightweight garments. Metal zippers are constructed of individual metal teeth that are joined together and used in heavier garments and bags. Plastic zippers are similar to metal zippers, but their teeth are made of plastic materials instead of metal, and they are used in lighter garments and bags. Invisible zippers are concealed when closed, and the coils or teeth are located behind the fabric, which makes them ideal for formal attire.

Through the years, zippers have evolved into different shapes and sizes, making it easier to adapt them to modern products. While we take the simple zipper for granted today, it remains an ingenious and indispensable invention that has had a significant impact on modern fashion and everyday life.

Uses of Zippers in Fashion and Industry

Zippers are a staple in both the fashion and industrial world. They are versatile and functional, making them an essential component in various products. Zippers were invented in the late 19th century and quickly made their way to clothing and bags, making life more comfortable and convenient for people. Let's explore the different ways zippers are used in fashion and industry.

Zippers in Clothing

From jackets to dresses, zippers can be found in almost every type of clothing. Zippers provide a reliable way to open and close garments, making them easy to put on and take off. They are also essential in keeping clothing securely fastened. Zippers come in many styles, colors, and lengths, allowing garment makers to choose the right zipper for their design. They can be placed on the back, side, or front of a garment, depending on the design and need.

For example, zippers on jackets allow wearers to adjust the opening, providing ventilation or protection from the cold. On the other hand, zippers on dresses and skirts offer wearers a way to control the level of modesty and comfort they want.

Furthermore, zippers are also used in sportswear, providing athletes with clothing that can withstand rigorous activities. They allow sports clothing to fit securely, providing ease of movement to the wearer.

Zippers in Luggage and Bags

Zippers are also widely used in bags, suitcases, and backpacks. These products require a secure and accessible opening mechanism to prevent items from falling out. Zippers provide a reliable way to access packed items and help secure them during transit. Bags with zippers also offer an element of convenience as they allow easy access to personal belongings.

Zippers Safety Concerns and Recalls

Zipper Invention and Evolution

The first patent for a zipper-like fastener was issued to Elias Howe in 1851. However, it was not commercially successful. The modern zipper was invented by Whitcomb Judson in 1893. Known as the "clasp locker," it resembled a modern zipper but was unreliable and difficult to use. It was not until Gideon Sundback, a Swedish-American engineer, made significant improvements to the design that the zipper became widespread. Sundback's "Hookless No. 2" design, patented in 1917, used interlocking teeth with a slider that could fasten and unfasten them. The name "zipper" was coined by the B.F. Goodrich Company in 1923, which used Sundback's design for their rubber boots.

Zipper Safety Risks

While zippers have become a ubiquitous fastening device, they can pose safety risks, particularly to young children, if they accidentally swallow or inhale detached pull tabs or if they catch their fingers or other body parts in the moving slider. Between 1991 and 2015, the U.S. Consumer Product Safety Commission reported more than 20,000 zipper-related emergency room visits. The majority of those injured were children under the age of 5.

Zipper Safety Standards

Various organizations have established safety standards and guidelines for zipper designs, manufacturing, and labeling to prevent accidents and ensure compliance. One such organization, ASTM International, developed the F2959 Standard Safety Specification for Soft Infant and Toddler Carriers, which includes guidelines for zipper design, strength, and placement. The standard requires that pull tabs be permanently attached to the slider and that they cannot detach without using a tool. It also requires that zippers be covered with a flap or fabric guard to prevent pinch points and that any exposed zipper tape ends be folded and sewn securely.

Recent Zipper Recalls

Despite safety standards, zipper recalls have taken place in recent years due to design flaws, including faulty sliders and pull tabs or the presence of toxic materials like lead and phthalates in zipper parts. In 2009, the U.S. Consumer Product Safety Commission announced the recall of one million JC Penney children's hooded sweatshirts due to potential strangulation hazards caused by drawstrings and zippers. In 2010, another major recall took place when the U.S. Food and Drug Administration announced the recall of more than 100,000 catheters due to defects in the zipper seal. In 2016, Nike announced a recall of more than 30,000 pairs of their Air Max shoes due to the possibility of a part of the zipper separating and posing a tripping hazard.In conclusion, while zippers are a convenient and essential part of our daily lives, they do pose certain safety concerns that must be understood and addressed. Proper manufacturing, labeling, and design can help prevent accidents and protect consumers from harm.
