History of the Zipper

History of the Zipper

The history of the humble zipper is a surprisingly short one, considering how ubiquitous this small device is now. Compared to previous fasteners, the zipper was fairly complex and so required “modern” machinery to design and produce it.

Despite being short, the history of the zipper is pretty interesting. So, let’s look at when zippers were invented and who invented the zipper.

Who Invented the Zipper?

A Swedish-American engineer called Gideon Sundback is generally credited with inventing the modern zipper as we know it. He registered his first patent for the device in Germany in 1909, but it wasn’t until 1917 that he received a patent for a device called a “separable fastener”. As the name suggests, this was the modern zipper in its first true design.

But as with any good invention, Sundback didn’t invent the zipper in a vacuum. He built upon previous designs and concepts that led to the idea of a zipper. A quick summary is as follows:

In 1851, inventor Elias Howe came up with a garment fastener that was essentially a complicated drawstring. However, he was too busy inventing the sewing machine, so he stuck with that.

In 1893, Whitcomb Judson developed a more complex type of hook-and-loop fastener for shoes. It looked similar to a zipper but without the slider to draw both sides together.

Between 1909 and 1917, Sundback adapted the design of the zipper to increase the number of teeth to make zippers more secure.

In 1923, Sundback sold his rights to Martin Othmar Winterhalter, who added ribs and grooves rather than joints and jaws (different ways of fastening zipper sides together).

Initially, zippers were used mainly in shoes and tobacco pouches. This is partly because clothes were fastened with buttons or laces, which most people were content with. After all, if it ain’t broke, don’t fix it!

When Were Zippers Invented?

The zipper was invented (technically) in 1917, but it wasn’t until 1923 that the name was first used. An American company called B.F. Goodrich Company used Sundback’s design on boots and coined the term zipper. Goodrich came up with the name based on the noise a zipper makes when you use it!

Zippers remained an institution in footwear for nearly 20 years until, in the 1930s, they were added to children’s clothes. Marketing campaigns labeled them as improving kids’ independence because they meant they could dress themselves. From there, zippers exploded into adults’ fashion, starting in men’s pants as the fly and making their way into womenswear.

Interestingly, it was around this time that the idea of a fully separating zipper took off. Until now, zippers were used for drawing together 2 sides of a garment, such as fastening boots or doing up the back of children’s overalls.

A fully separating zipper doesn’t take that much more technology. Rather than having connected teeth sewn into a garment, the zipper has an insertion pin and retainer box. These essentially allow you to align both sides of teeth before running the slider up them.

The first real use of a separating zipper was on jackets, specifically leather jackets. This was partly because of changes in fashion – until the 1920s and later, casual fashion closely resembled formalwear. Most men wore suits and women wore dresses. You’d wear these regardless of what you were doing, although there’d be differences in fabrics and cuts depending on the time of day and event.

However, as more people shifted towards obvious casual wear (such as trousers for women and no ties for men), the zipper came into its own. Plus, it wasn’t until people saw the zipper in action that they realized how time-consuming buttons actually are!

Another important factor was women’s suffrage. Lace-up dresses were seen as oppressive and unnecessary – women were shifting towards flapper dresses and trousers. Although these didn’t necessarily use zippers, it was the beginning of a trend away from stuffy, formal clothes.

What Do We Use Zippers For?

Zippers are now, without question, the most common type of fastener used. They’re fast and convenient and offer greater garment security than buttons. Although there isn’t really anything we don’t use zippers for, some of the most common uses include:

Jackets, hoodies and vests – zippers make these much easier to get on

Bags

Upholstery items - cushions, pillows, etc.

Outdoor items – sleeping bags, tents, boat covers, etc.

Clothing garments – pants, dresses, skirts, etc.

Leather goods

Another major benefit of the zipper is that it can easily be made waterproof. While the basic design isn’t watertight, we can do this by applying waterproof coatings during the production process. Doing so means no water will get through the metal teeth or the tape.

But we can go one step further and have airtight zippers too. NASA developed an airtight zipper that it uses on space suits. Not only do these zippers need to be airtight but they also need to resist massive differences in air pressure. Considering they still follow the basic zipper design, it’s impressive that such a humble item can be so functional.

How a Zipper Works

Considering how technical zippers are compared to buttons, their design is actually pretty simple. To understand how they work, we must briefly discuss the basic components, which are:

The teeth. These are the metal (or plastic) parts that run down both sides of the zipper.

The slider. This is the part you move up the teeth to draw them together.

The tape, which is what’s sewn into the garment to fix the zipper in place.

Insertion pin. This is specific to separating zippers and runs through the slider into the retainer box.

Retainer box. This is the part at the bottom of the zipper that holds both sides of the teeth together.

So, how does a zipper work?

In short, the slider runs up the teeth and draws them together. The teeth are shaped like hooks that fit into hollows on the tooth below. When forced together at a certain angle, the teeth lock into place by the hook fitting into the hollow.

Done properly, it’s almost impossible to separate the teeth apart by pulling on them. A high-quality zipper will take a lot of force, which is why they’re so useful for things like bags, but also for clothing. However, the slider can easily separate the teeth using a plow-shaped wedge. It pivots the hooks and hollows away from each other, drawing the teeth apart.

Although there are some minor differences between different types of zippers, they all follow this basic process. For example, invisible and double-sided zippers need slightly different functionality, but they still involve 2 sets of teeth locking together.

Considering we’re all so familiar with the concept of a zipper, the zipping process itself is quite complex. That said, a zipper is also very simple: it’s 2 strips of metal teeth that lock together. But the complexity of how this works is part of why they weren’t invented until recently. It wouldn’t have been possible to design and manufacture the important parts without modern industrial equipment.

Final Thoughts

Hopefully, you now know everything you wanted to (and more) about the history of the zipper! Compared to buttons and laces, zippers are very modern, but they were also fundamental in the clothing revolution of the early 20th century. Without zippers, we wouldn’t have such an extensive range of clothing.

Perfect Zippers for Safety Wear Lino Safety Professinoal Safety Clothing Suplier

A zipper can’t make a good dress, but a zipper can ruin good reflective wear. This statement fully illustrates the importance of zippers to a garment.

With consistent development, the performance, structure, and materials of zippers are changing. There are so many choices. So how do you choose the right zipper? This article will introduce the structure, types, sizes, major zipper brands, the latest product recommendations, main problems, and how to solve them.

It can be confusing to choose the right zipper for your garment. Make sure to consider your needs and requirements when selecting a zipper. Here are some tips on how to choose the perfect zipper for your reflective clothing:

Structure of a Zipper

The zipper is composed of the teeth, slider, top and bottom stop, or locking parts. Among them, the chain teeth are the key part, which directly determines the side pulling strength of the zipper. Generally, the zipper has two tapes, each piece of tape has a row of teeth, and the two rows of teeth are staggered with each other. The zipper head grips both sides of the teeth, and with the help of the pulling loop sliding, can make both sides of the teeth engage or disengage each other.

Types of Function

Zippers are mainly divided into Closed-end zippers, Open-end zippers, and Tow-way zippers.

The most common types of zippers and what they’re used for

Closed-end zippers

Closed-end zippers mean that the end is fixed and can only be pulled from the front. When the zipper is fully open, the two straps are connected by the backyard and cannot be separated. Suitable for general bags, pockets, pullovers, and trouser flaps.

Open-end zipper

Open-end zipper is the most common zipper used for garment placket, it means that there is no bottom stop and there is a tight locking piece, there are left and right inserts. The locking piece is equivalent to a closed-end zipper when it is locked, and the zipper can be separated by pulling the slider against the locking piece. Designed for clothes that need to be pulled apart frequently.

Two-way zipper

The two-way zipper has two sliders that can be opened or closed from both sides. The zipper can be opened completely by pulling both sliders against the locking member to separate them. If the safety vest or jacket is a longer style, the two-way zipper should be used.

Standard Slider Functions

The slider is also a very important part of the zipper, we usually choose a zipper according to the product needs, such as double-sided clothing, we need to use a Reversible slider; like sleeping bags or tents, and we will use Double pull slider; and more for skirt or pocket invisible slider. Of course, for most of the garments without special requirements, we will use one-way A/L slider.

The slider is more prone to problems, such as broken sliders, zippers that can not be pulled, zippers bursting open, and other problems. At this time, we have to check whether the size of the slider is correct and whether the torque of the slider is up to standard. If the slider is coating or electroplating, the color fastness test should be checked to see if the color fades.

Pullers

Pullers have many options and can be customized. For example, if the zipper model is small, an extra puller could be added.

Styles of zipper

There are three kinds of zippers according to the material of teeth, metal zipper, coil zipper, and Plastic zipper. We will introduce the difference between the three kinds of zippers and how to choose them.

Metal zipper

Metal zipper is zipper teeth are made of copper, white brass, or aluminum, which has strong lateral tension, is not easy to be destroyed and has high safety performance. It is mostly used on jeans, jackets, leather products, and bags. The teeth are mainly available in the following colors.

Metal zippers look high-end and the price is high. The overall weight is heavier (not for the light category), the durability is not very good and the phenomenon of non-smoothness will occur sometimes.

Coil zipper

Coil zipper also known as nylon coil zipper, is a type of zipper whose teeth/elements are made from coiled monofilament, which is traditionally nylon. It is the one with the highest smoothness. Compared with metal zippers and plastic zippers, coil zippers are low-cost and popular. The coil zippers are widely used in garments, home textiles, bags, and tents,

There are mainly two kinds of coil zippers, front coil and reversed coil.

The invisible zippers and Waterproof Coil zippers are the types that are used more in garments.

An invisible zipper is a zipper that is hidden within a seam. The only part that is seen is a slender zipper pull at the top. It’s mainly used in dresses, tight sportswear, inside pockets, and other places.

Waterproof Coil Zipper is mostly used for products with waterproof needs, commonly used in outdoor sportswear, such as diving suits, ski suits, rushing suits, raincoats, etc. There are three main types of membrane variations: shiny clear membrane, matte clear membrane, and matte colored membrane with a high-quality appearance. Waterproof zippers are all reverse-loading sliders.

Plastic Zipper

Plastic zippers are made of polyester plastic by dye color matching and lined up by an injection molding machine. Plastic zippers are used more in clothing jackets and bags and have a fashionable texture. The durability is the best among the three kinds of zippers.

There are many plastic zipper teeth styles, such as Sagittate Teeth， Multi-color Tape&Teeth， Square teeth, etc.

Plastic Zippers also have some special items, like Transparent Teeth, Reflective zippers, Metal look zippers, and so on.

Various sizes of zippers

The size of the zipper is determined by the size of the teeth, which are engraved on the reverse side of the slider. The common models are #3, #4, #5, #8.

How do we decide which model to use?

The #3 zippers are mostly used in pockets, trouser closures, patchwork and removable areas (e.g. sleeves removable, hats removable), storage areas (e.g. hats stored to the collar), and children’s garments.

The #5 zipper is the most common and most used type and is generally used for placket closures, pockets, side seam openings, etc.

The #8 /10 zipper is commonly used for placket closures on heavy-duty garments, such as skiwear, rashers, down jackets, etc. Men’s jackets are more often used with #8 /10 zippers.

The Significance of the Zipper

You probably don’t think much about the significance of the zipper. Often taken for granted, this masterfully engineered fastener is essential to most people’s daily lives. While you could live without it, modern life is made much more convenient by this seemingly simple device that is found on most jackets, backpacks, and pants. Learn about the history of this fastener and how it became so popular. 

The History of the Zipper

You may have never considered that zippers have a history. Zippers were invented more than 170 years ago, and now they’re the most popular fastener used today. The mechanism went through several rounds of engineering before it became the device that we all know.

The Original Zipper

The first zipper was invented by the same person who invented the sewing machine. Too busy promoting their more popular invention, Elias Howe’s zipper wasn’t much of a success. Whitcomb Judson improved upon Howe’s design in time for the 1893 Chicago World’s Fair. He called it a “clasp locker,” and again the invention was not successful.

Invention of the Modern Zipper

It was not until the early 1900s when Gideon Sunback was working for the Universal Fastener Company that he invented the modern zipper. Sunback was a head designer at the plant in Hoboken, NJ, where he received a patent for his design in 1917. Further, Sunback also invented a machine to create the zipper. The first one could produce at least a few hundred feet of zipper chain per day.

First Uses for Zippers

The first zippers were advertised as shoe fasteners. The G.B. Goodrich company used them for their rubber boots and started calling the fasteners zippers. The common use of the term “zipper” is attributed to G.B. Goodrich. Additional original uses for zippers were for military equipment and uniforms during World War I.

The Rise of the Zipper

How did zippers become part of mainstream fashion? Once designers learned how simple they were to sew into clothing, as well as how versatile they could be, zippers were found in advertisements across the globe. French fashion designers praised them for revolutionizing both men’s and children’s clothing. As the trend picked up in the United States, zippers became a preferred fastener to buttons or ties. Let’s next take a look at why the zipper is important in fashion.

Men’s Fashion

When it comes to men’s fashion, zippers are less about aesthetic and more about function. Once designers realized how easy zippers made getting in and out of trousers, they knew men would love them. Zippers are easily concealed in men’s clothing but are also easily accessible so you can open your pants to use the restroom. Early advertisements for men’s pants with zippers were enticing because they played on the idea that those who wore them would have an easier time in the bathroom.

Women’s Fashion

Zippers on women’s clothing are usually about ease. The zippers are typically hidden and may be found on jeans, a blouse, or a dress. Many modern women’s clothing and accessories also feature fashion zippers. Exposed zippers are common on handbags, boots, belts, and hats. Some zippers on women’s clothing don’t serve any function other than appearance. This shows how far our fashion industry has come with this unique fastener.

Children’s Clothing

The zipper gained popularity due to the way it was advertised for children’s clothing. Ads explaining that pants with zippers gave children more independence had mothers buying them in bulk. Children who have more independence do better in school. Kids like being able to take care of themselves, too. Nothing is more significant than a piece of metal or plastic that can give your child more confidence.

Mainstream Zippers

In addition to daily fashion, zippers are essential to many other facets of life. They are the most common fastener used to keep bags and cases of all sorts closed. One of the most common uses for zippers is on jackets and coats. You wouldn’t buy a jacket that didn’t have a zipper, and you might stop using your jacket if the zipper broke.

Outdoor Gear

Outdoor gear is another mainstream use for zippers. If you have a tent, boat, or other camping or marine equipment, it likely has a zipper to keep it secure. Zippers for outdoor gear are typically heavy- duty. For instance, marine zippers are water-resistant. Further, manufacturers use coil zippers for tents to ensure flexibility. You always want to buy top-quality gear to ensure it comes with a good zipper.

Alternative To Zippers

Prior to zippers, people used buttons and ties to fasten items like shoes and jackets. Since the invention of the zipper, it has inspired other fasteners, but none offer as strong of a hold. For instance, mechanisms for resealable bags and Velcro were designed based on zippers. While strong forms of Velcro exist, they aren’t as practical as zippers. Velcro wears down over time and is challenging to maintain.

Zipper Care

Clean Your Zipper

Taking care of a zipper is easy if you know how to clean and properly maintain it. First, you should understand the most important parts of a zipper—the chain, teeth, slide, and pull tab. Your zipper shouldn’t be missing any teeth, and the slide shouldn’t wobble on the chain. The most common reason a zipper gets stuck is that something is caught in the teeth. You should remove threads, grime, and other gunk before trying to loosen the slide. Pull gently on the tab so you don’t break it. 

Lubricate Your Zipper

To protect your zipper and ensure the slide glides over the chain properly, use a lubricant. You’ll know your zipper needs lubricant if the slide catches on the chain as you try to use it. The best things to use to grease your zipper are: 

Granite pencil

Windex

Crayon wax

Petroleum jelly

Lip balm
