Do you know that lock sliders have different types: auto-lock slider and pin-lock slider? What are their differences?Auto-lock sliders: A small locking mechanism inside the slider holds the slider in place until the slider tab is pulled, which means the slider will be locked when there's no force. This prevents the slider from moving by itself or by mistake. It's widely used on zippers for sportswear,  jackets, furniture, etc.Pin-lock sliders: There's a pin in the slider, when the puller is pressed down into the zippers, the pin will lock the sliders. They're widely on zippers for bedding, upholstery, clothing, etc.

When was the zipper invented? The zipper was (technically) invented in 1917, but the name was first used in 1923. The American company BF Goodrich Company adapted the Sundback design for boots and coined the term "zip". Goodrich came up with the name based on the sound the lightning bolt makes when used! Zippers remained an important part of footwear for almost 20 years, until the 1930s, when they were added to children's clothing. Marketing campaigns describe them as increasing children's independence because they mean they can dress themselves. Since then, zippers have quickly made their way into adult fashion, starting with men's trouser panels and gradually making their way into women's clothing. Interestingly, it was at this time that the idea to completely unfasten the zipper began to emerge. Until now, zippers have been used to tighten two sides of clothing, for example to fasten boots or sew the back of a baby's overalls. Fully removable zippers require no special skills. Instead of having connected teeth sewn into clothing, this zipper has inserts and holding boxes. Essentially, they allow you to line up the sides of your teeth before moving the slider up. The first real use of tear-off zippers was on jackets, especially leather jackets. Part of this is due to changes in fashion-up until the 1920s and beyond, casual fashion was very similar to formal wear. Most men wear suits and women wear skirts. You'll wear them no matter what you do, although the fabric and cut may vary depending on the time of day and activity. However, as more and more people moved towards overtly casual clothing (such as trousers for women and no ties for men), zippers came into play. Plus, people don't realize how time-consuming buttons really are until they see the zipper in use! Another important factor was women's suffrage. Dresses with straps were considered oppressive and unnecessary - women began to move towards fashionable dresses and trousers. Although they don't necessarily use zippers, they are the start of a trend away from strict formal wear.

What's airtight zipper? Airtight and watertight zippers are designed to provide a seal that keeps out air, moisture, and other contaminants. These zippers are used in a wide range of applications, from outdoor gear to medical equipment. Working principle of airtight zippers: 1) Its unique structural design and the materials used. The structure of this zipper is similar to a standard ordinary nylon zipper, including three basic components: joints, chain elements and textile fabrics. 2) With a waterproof layer (TPU film, thermoplastic polyurethane) with waterproof properties. TPU is coated on the textile fabric multiple times and is completely integrated with the fabric. This design allows the chain elements to bite tightly, and during the zipper closing process, the TPU film is tightly squeezed on both sides of the center seam, thus forming a double sealing effect, effectively preventing moisture and gas penetration, achieving waterproof and airtight purposes.

Waterproof zippers, also known as water-resistant zippers, are specialized closures designed to prevent water penetration. They are commonly utilized in outdoor gear and clothing items like rain jackets, backpacks, tents, and dry bags. Waterproof zippers feature a combination of materials and design elements that effectively resist moisture. Typically, these zippers are constructed with a TPU or PET coating on the zipper tape, creating a barrier against water. The zipper teeth are designed to interlock tightly, minimizing the chance of water seeping through. While they offer significant protection against rain, splashes, and wet conditions, it's important to note that complete waterproofing may depend on other factors like fabric choice, seam construction, and overall product design. Care instructions provided by the manufacturer should be followed to maintain the water-resistant properties of items with waterproof zippers. This entails avoiding excessive force or abrasion that could compromise the zipper's integrity or the effectiveness of the waterproof coating. In summary, waterproof zippers are specially engineered closures that prevent water from penetrating gear and clothing items. They employ a combination of materials and design features to resist moisture. While they offer substantial protection, other factors also contribute to the overall water resistance of a product. Adhering to manufacturer guidelines for care and usage is crucial to ensure the longevity and effectiveness of waterproof zippers.

Plastic zippers become more and more popular in recent years. Many new beginners may wonder, which one is better for production investment, below the information may be able to help. Metal zippers and plastic zippers are two common types of zippers used in various applications. Here are the key differences between them: Material: Metal zipper: Metal zippers are made of metal components, typically brass, aluminum, or nickel. The teeth and sliders are constructed from metal materials, providing strength and durability. Plastic zipper: Plastic zippers are made of plastic components, usually polyethylene (PE) or polyacetal (POM). The teeth and sliders are made of plastic, offering flexibility and lightweight characteristics. Appearance: Metal zipper: Metal zippers have a more traditional and classic appearance. They are often used in clothing and accessories where a sophisticated or rugged look is desired. Plastic zipper: Plastic zippers come in a wide range of colors and designs. They offer more versatility in terms of appearance and can be used in various styles of garments and products. Functionality: Metal zipper: Metal zippers are generally considered to be stronger and more durable than plastic zippers. They can withstand heavier loads and frequent use, making them suitable for applications that require greater strength and longevity. Plastic zipper: Plastic zippers are lighter and more flexible than metal zippers. They provide smooth operation and are often used in lightweight garments, bags, and other products where weight and flexibility are important. Cost: Metal zipper: Metal zippers are usually more expensive than plastic zippers due to the higher cost of metal materials and manufacturing processes. Plastic zipper: Plastic zippers are generally more cost-effective and budget-friendly compared to metal zippers. The choice between a metal zipper and a plastic zipper depends on the specific requirements of the application. Metal zippers are preferred for heavy-duty or high-end products that require strength and durability, such as jeans, jackets, and luggage. Plastic zippers are commonly used in lightweight garments, bags, and items where weight and cost are considerations. It's important to note that "better" is subjective and depends on the specific needs of the project. Both metal and plastic zippers have their advantages and are suitable for different applications. Manufacturers and designers choose the type of zipper based on factors such as aesthetics, functionality, durability, and cost.

Nylon zipper are widely used in clothing, luggage, beddings, and so on. 2, Metal zipper are the classic zipper type, found mostly in jeans, jackets and bags today. The teeth are made by brass, aluminum or stainless steel. All these zippers are basically made from flat wire. A special type of metal zipper is made from pre-formed wire, usually brass, but sometimes other metals, too. Only a few companies in the world have this technology. This type of pre-formed metal zipper is mainly used in high grade jeans-wear, work-wear, etc., where high strength is required and zippers need to withstand tough washing. 3, Plastic zipper are identical to metallic zippers, except that the teeth are plastic instead of metal. Metal zippers can be painted to match the surrounding fabric; plastic zippers can be made in any color of plastic. Plastic zippers mostly use polyacetal resin, though other thermoplastic polymers are used as well, such as polyethylene. Used most popularly for sportswear, windbreaker and so on. 4, Invisible zipper have the teeth hidden behind a tape, so that the zipper is invisible. It is also called the concealed zipper.

Structure Of A Closed End Zipper A zipper is a device used for temporarily joining two edges of fabric or other materials by means of interlocking teeth. It is also sometimes referred to as a zip or a slide fastener. Zippers are commonly used on clothing, bags, and other items that need to be opened and closed frequently. A closed-end zipper is a type of zipper where the two ends of the zipper tape are sewn or fused together, creating a solid stop at one end of the zipper. This type of zipper is also known as a bottom stop zipper or a finished zipper. Closed-end zippers are commonly used in applications where the zipper needs to be completely closed at one end, such as on the bottom of a jacket or the opening of a purse. Closed-end zippers come in a variety of sizes, styles, and materials, and can be made with either coil or molded plastic teeth. They can also have different types of sliders, including auto-lock sliders that hold the zipper in place when closed, or non-lock sliders that allow the zipper to be opened and closed without locking. Closed-end zippers are often found in ready-to-wear garments and accessories, but can also be purchased separately for use in sewing projects.
