Features of Dyed Aramid Webbing
High strength: Aramid webbing has extremely high strength, reaching a level greater than 28 g/denier, which is 5-6 times that of high-quality steel.
Excellent modulus and toughness: Its modulus is 2-3 times that of steel or glass fiber, and its toughness is twice that of steel.
Lightweight: Despite its excellent performance, aramid webbing weighs only 1/5 of that of steel.
Wide temperature range: Aramid has an extremely wide continuous use temperature range and can maintain stable performance from -196°C to high temperatures.
Dyeing performance: Dyed aramid webbing can present rich colors through a specific dyeing process while maintaining the original excellent properties of the webbing.
Dyeing process: The process of dyeing aramid webbing is relatively complicated because aramid fibers are hydrophobic fibers and have no affinity for dyes. Therefore, specific carriers or auxiliaries, such as cationic dyes and aromatic carboxylates, are usually required for dyeing to improve the dye uptake and color fastness of the dye. In addition, various process parameters, such as pH, temperature, time, etc., need to be controlled during the dyeing process to ensure the dyeing effect and quality.
A synthetic fiber that often goes into the creation of quality flame resistant fabric is aramids, which can be split into two types: meta aramids and para aramids. These fibers are used in a range of applications, including aerospace and military applications, body armor fabric, marine cordage, marine hull reinforcement, an asbestos alternative, and protective clothing.
Meta aramids are commonly manufactured by spinning the fiber in a chemical solution a process referred to as wet spinning. This results in a semicrystalline fiber with a molecular chain partially oriented along the fiber's axis.
Compared to nylon and polyester fibers of mid tenacity, meta aramid fibers (such as Nomex®) are highly resistant to temperature, chemical degradation, and abrasion. Fibers with these tenacity properties are capable of withstanding high levels of stress when exposed to flames or temperatures of up to 752 degrees Fahrenheit (400 degrees Celsius).
Meta aramids are softer and conduct electricity better than para aramids.
Benefits of Meta Aramids
Flame Resistance
Durability
Comfort
Ease of Care
Meta aramid fibers are thermally stable, inherent FR fibers. They are strong and abrasion resistant. While they can be dyed in several shades, they don't hold color well and are susceptible to color change.
Para aramid fibers (such as Kevlar®) are made using the dry jet method, which results in fibers with fully extended liquid crystal chains along the fiber's length that are highly crystalline, which enhances the fiber's strength. These fibers display high tensile strength (the maximum stress that can be sustained by the material) and modulus behavior (the tendency of a material to deform when stressed).
The increased strength of para aramids is what makes them valuable in bullet proof body armor as well as in the military and aerospace environments. In industrial settings, para aramids are also a common ingredient in safety equipment that require FR properties, such as gloves and helmets.
In comparison to meta aramids, para aramids are stiffer and have greater tenacity and strength. But they are sensitive to chemicals, and the presence of acids, alkalis, and bleaches degrade the strength of para aramid polyamide.
Strength
Lighter than steel
Heat resistance
Chemical resistance
Unaffected by moisture
Para aramids are extremely strong and abrasion resistant. As with meta aramids, they can be dyed but do not hold color well. Fabrics made with para aramids tend to have a compromised appearance over time.
Choosing The Right Product for You
Meta aramids are incredibly durable, allowing them to be exposed to high temperatures as well as fire exposure.
In contrast, para aramids are incredibly strong. The higher levels of crystallinity in para aramid fibers increase their strength.
In general, Aramid fibers offer excellent protection against flashover and chemical splashes. Since they possess a low molecular weight, FR fabrics made up of aramid fibers allow a more comfortable garment without compromising on safety.
Production Process of Flame-Retardant Webbing
Flame-retardant webbing is an essential component in various industries, including safety equipment, military gear, automotive, and aerospace. This specialized webbing is designed to resist ignition and prevent the spread of flames, offering critical protection in environments where fire hazards are a concern.The production of flame-retardant webbing involves several key steps to ensure its effectiveness and durability:
Material Selection
The process begins with selecting high-quality fibers that inherently possess flame-retardant properties or can be treated to achieve them. Common materials include aramid fibers (such as Kevlar), modacrylics, and treated polyester.
Chemical Treatment
For fibers that do not naturally resist flames, a chemical treatment is applied. This involves immersing the fibers in a flame-retardant solution that coats and penetrates the material, providing a protective barrier against fire.
Weaving
The treated fibers are then woven into webbing using specialized looms. The weaving process must ensure consistent tension and alignment to produce a uniform and strong webbing structure.
Quality Control
Post-weaving, the webbing undergoes rigorous quality control tests. These tests check for flame resistance, tensile strength, and overall durability. The webbing is exposed to controlled flame sources to verify its ability to withstand fire and prevent its spread.
Certification
To ensure safety and compliance, flame-retardant webbing is certified by relevant authorities. Certifications such as NFPA (National Fire Protection Association) and UL (Underwriters Laboratories) indicate that the webbing meets stringent fire safety standards.
How to Choose the Right Webbing
Understanding Webbing Types & Materials
First, let's briefly talk about webbing materials. webbing options are made from six different materials. Some material offerings have a few varieties to choose from, while others are only offered in one standard or heavy duty variety:
Cotton/polyester blend webbing: Heavy duty variety.
Dyneema® webbing: Standard variety.
Nylon webbing: Standard, heavy duty and tubular varieties.
Polyester webbing: Grosgrain, standard, super heavy duty, tubular and seat belt varieties.
Polypropylene webbing: Standard and heavy duty varieties.
Sunbrella® acrylic/polyester blend webbing: Standard variety.
Most of these webbings are available in multiple widths and colors, so you can customize your project as much as possible.
In addition, webbing comes in both flat and tubular forms. We offer flat versions of all our webbings. You can also get tubular webbing in nylon and polyester. Tubular webbing is hollow, stronger than flat, and able to hold a rope or cord. Using rope or cord with tubular webbing is not required though - it can be used the same as flat webbing.
Key Webbing Features to Consider
Not every webbing can be used in every project or environment because of the different fibers used to make them. Knowing the properties of each webbing is crucial to picking the one that best fits your project. Before you decide, think about these important factors:
UV resistance: Will your project be fully indoors, fully outdoors or a combination?
Abrasion resistance: Will your webbing be used in a high-traffic area or exposed to high levels of rubbing or chafing?
Buoyancy: Do you need webbing that floats on water?
Water absorption: Do you need webbing that stays mostly or completely dry when exposed to water or other liquids?
Breaking strength: Do you need webbing for a weight-bearing application?
Heat resistance: Do you need webbing that can withstand high temperatures?
Stretch: Do you need webbing that has some give or that resists stretching?
Webbing is used in a variety of projects including shade sails, dog collars and leashes, and as support straps on bimini frames.
Another major factor to consider is sewability. Some webbings might be too much for a basic home sewing machine to handle. So if you don't have a heavy-duty machine, you may struggle to sew webbing. This is especially true if you are folding the webbing in half to sew loops or handles, or if you're adding webbing to two or more layers of fabric.
Webbing Selection Simplified
Once you've answered the questions above, use these charts to determine which webbing type has all the properties you're looking for. These free resources allow you to search by either the project you want to make or the type of webbing you have. By using both charts, you can be sure you're choosing the webbing that meets all your project needs.
