It holds substantial importance across multiple industries thanks to its durable structure and ability to both block water and provide insulation.
Because it is synthetic rubber material known for its versatile material qualities, neoprene fabric is ideal choice for wetsuits, medical devices and industrial applications like tank jacket, and these applications mainly benefit form it’s resistant, waterproof, and insulating properties.
The article will give you a whole view of neoprene material, from its manufacturing process to the unique benefits, let’s start the fantastic journey!
Understanding Neoprene Fabric from Birth to Application
Neoprene fabric is always called as neoprene rubber, but they are not the same thing.
Neoprene rubber is a type of synthetic rubber derived from polychloroprene rubber, a petrochemical substance.
But neoprene fabrics is the combined of neoprene rubber and fabrics, which means the neoprene fabric equals to neoprene rubber plus fabrics, so easy right? But the processing is not so easy because we have to control every procedures strictly so that can have the similar elasticity, chemical resistance, and good performance under extreme temperatures with natural rubber.
Before we introduce neoprene fabrics, a basic knowledge of neoprene rubber is necessary, because it is the main part of neoprene fabrics.
Born from World War II, global rubber shortage period, so it’s imaginable the neoprene rubber is created with some with duties, poor guy.
But this guy completes his mission, because it has closed-cell structure inside, born with talents! so it obtains insulation, waterproof, shock absorption features, and now it has been a versatile material and used for protective gear like wetsuits, gloves, and cup coolers.
History of Neoprene Fabric
World War II, a cruel time, but also a new things burst out time.
Because natural rubber sources were disrupted, DuPont produced neoprene rubber from chloroprene in 1930.
With the reliable waterproof performance, resist chemicals, neoprene is quickly become an ideal alternative and found its place in many industries. as manufacturers searched for synthetic alternatives that quickly became essential in various industries. The material received recognition for delivering dependable waterproof protection while resisting chemicals and remaining flexible under extreme conditions.
Back to it’s feature of chemical resistance and performance under both extreme temperatures and harsh environments, neoprene is commonly used for everything from military applications to scuba fabrics, and these are also the first industrial applications the neoprene is used, because it is created for some military requirements.
With the neoprene characteristics spread widely, soon it is also used on civilian fields, and it is discovered more advantages UV radiation, saltwater, and harsh industrial chemicals.
So not the waterproof applications is basically inseparable from it, like the gaskets, wetsuits, and sports equipment
Manufacturing Procedures of Neoprene Fabric
The neoprene rubber comes from the combination of polychloroprene and other additives, under a full mixing, high temperature, and pressure, it comes to synthetic rubber material.
Meantime the polymer structure formed, and this gives this material the renowned durable, tear-resistant, and abrasion-resistant qualities.
All the applications like medical applications, sporting goods, gaskets, and seals are thanks to these advantages.
Mainly 5 production processes are required for the neoprene fabrics creating, and following we’re showing the 5 procedures from natural rubber to neoprene fabric one by one.
Procedure 1: Starting with Raw Neoprene Rubber
We mix synthetic rubber with other ingredients such as carbon black and stabilizers, then the elastic and neoprene sheet comes into the world.
But after this procedure, the neoprene rubber is still solid, with thickness about 25mm, and the color can be black, pure white and rice white.
In this progress, the elasticity comes from the natural rubber, the resistance to wear and tear comes from synthetic rubber. As the Chinese saying goes “the disciple is better than the master”, now the neoprene rubber not only has the characteristics of its parents, also develops more advantages like high level of resistance to environmental factors such as extreme weather, UV rays, and even certain solvents.
Procedure 2: Foaming Process
To make neoprene fabric to be soft, it’s necessary to introduce air into the solid neoprene sheet, which can give neoprene a closed-cell foam structure, then it brings the waterproof, shock absorption, and insulation properties, then it is widely used on medical braces, protective pads, wetsuits
Procedure 3: Connecting
Connect the neoprene sponge beds end to end with water glue, to make it be a whole line like “snake”. This step’s purpose is to accumulate the raw material and ensure the slicing machine’s working smoothly, also will give the final neoprene fabric a better appearance.
Procedure 4: Slicing
After foaming, the neoprene is molded into a 50cm thickness neoprene “bed”, more like a mattress.
To meet the intended uses, such as 2mm-6mm for wetsuits, 2.5mm-3mm for insulated gloves, 3mm-5mm for protective pads, the neoprene beds are sliced into sheets from 1mm to 12mm
Procedure 5: Laminating
After the neoprene foam are sliced into certain thicknesses, it needs to laminate with fabrics like nylon, polyester, velcro, terry….to enhance the fabric’s durability, flexibility, and comfort features.
In the true sense of neoprene fabric comes to the world after laminating, now it belongs to synthetic fabric and synthetic fibers, which you can find from fabrics wholesalers.
It’s optional to laminate the both sides or only one side, and this is depends on the specific needs. Like for wetsuits, the smooth skin is popular, and this is neoprene sheet without lamination.
The fabrics participating can partly reinforce the neoprene rubber’s essential properties of tear resistance, shock absorption, and chemical resistance.
Besides, in order to make the neoprene fabrics more suitable for for products such as sports apparel, medical supports, and protective wear, we can do more deep-progressing to give it higher breathability, or friction, or aesthetics.
Procedure 6: Packing
After the neoprene rubbers are laminated with fabrics, the neoprene fabrics are born in reality.
The neoprene fabrics will be rolled in machine to make the size as smaller as possible, and packed in a strong PP bag as the first packing layer, then packed in a weaving bags.
After sticking the labels, these neoprene rolls are ready to be shipped by sea or by air.
Additional Deep-Processing Options for Neoprene Fabrics
Neoprene fabric is often customized to suit specific needs. Below are some common additional processing options:
Option 01: Printing
Neoprene is commonly printed with logos, designs, or other custom graphics.
This allows manufacturers to create personalized items, such as promotional products and branded gear.
Custom printed neoprene products are widely used in the advertising and fashion industries, where durability and style are key.
Also it’s available to supply white neoprene fabric for customers to have heat transfer printing. Our white neoprene fabrics can bear high to 400ºC degree and oil ink will not smudge or transfer to the neoprene rubber.
Option 02: Embossing
Neoprene sheets can be embossed for improved grip, traction, and keep aesthetics.
Also it’s optional to embossed on the fabric side, or embossed on the bare rubber side.
Shark-skin means neoprene rubber without going through a small shape of embossing, which seems like the shark skin, and this is widely used on wetsuits, medical supports, and athletic gear, where increasing friction is the key factors.
Option 03: Perforating
Perforating means punching some holes on the neoprene fabric sheets.
It’s available to perforating the overall neoprene fabrics, both the neoprene rubber and the fabrics. Also perforating only the middle-layer neoprene rubber is available, in which the neoprene fabrics look like a flat surface but the breathability enhanced greatly.
With the perorating progress, the neoprene fabrics can ensure comfort during extended wear in extreme temperatures.
The perforating holes have tens of types to choose from, which are mainly different on the holes size, holes shape, holes distance.
Option 04: Coatings
Neoprene can be treated with various coatings to increase its resistance to the elements.
For example, it may undergo Dust-proof coating for use in outdoor garments, or water-repellent coating for drysuits, UV protection coating for sun-protective-clothing.
