Aramid fabrics are synthetic fibers known for their excellent strength and heat resistance. Derived from aromatic polyamides, aramid fabrics are used in a wide range of industries due to their unique properties. You will learn more about aramid fabrics from this post, including types, production process, benefits, applications, and care. Of course, we will also provide the top 3 aramid fabric suppliers in China for you to choose from.
First, you should have a preliminary understanding of aramid fabrics. Aramid generally refers to aramid fiber, which is derived from aromatic polyamide and is widely used in various industries due to its unique properties. Aramid fiber, carbon fiber, and ultra-high molecular weight polyethylene fiber are known as the world's three major high-tech fibers. They have the characteristics of high strength, high temperature resistance, friction, flame retardancy, and good dimensional stability.
Aramid fabric is a synthetic fiber that belongs to the aromatic polyamide group. It consists of long, stiff polymer chains that are highly oriented along the fiber axis, giving the fabric exceptional strength and stiffness. Aramid fibers are lightweight and have excellent abrasion and organic solvent resistance.
Aramid fabrics are known for their outstanding properties, including
Tear resistance: Aramid fabrics do not scratch or even break under contact with sharp objects.
Flame retardancy: Aramid fabrics do not melt or drip at high temperatures.
Chemical resistance: Aramid fabrics are resistant to a wide range of chemicals, including acids and alkalis.
Thermal stability: Aramid fabrics retain their properties even at high temperatures, making them suitable for use in extreme conditions.
There are two main types of aramid fabrics: meta-aramids and para-aramids.
Meta-aramid fibers (e.g. Nomex) are known for their heat resistance and are often used to make flame-retardant clothing. Para-aramid fibers (e.g. Kevlar) are known for their high strength and are used for ballistic protection and reinforcement applications.
Meta-aramid fabrics are commonly used in protective clothing for firefighters and industrial workers, while para-aramid fabrics are used in bulletproof undershirts, ropes and tires. The main difference between these two types is their molecular structure, which influences their properties and applications.
The production of aramid fabric involves several steps, including polymerization, spinning, weaving or knitting, and dyeing and finishing.
The first step in the production of aramid fabric is the polymerization of aromatic diamines and diacid chlorides to form a polyamide solution.
The polyamide solution is then spun into fibers using a wet or dry spinning process, depending on the desired properties of the fabric.
The aramid fibers are then woven or knitted into fabric using specialized machinery, which determines the final texture and strength of the fabric.
After the fabric is formed, it is dyed and finished to enhance its properties, such as color fastness and durability.
Aramid fabric offers several benefits, including:
High strength and durability: Aramid fabric is lightweight yet incredibly strong, making it ideal for applications requiring high tensile strength.
Flame resistance: Aramid fabric does not burn or melt, making it suitable for use in flame-resistant clothing and protective gear.
Chemical resistance: Aramid fabric is resistant to many chemicals, making it suitable for use in hazardous environments.
Thermal stability: Aramid fabric retains its properties at high temperatures, making it suitable for use in high-temperature applications.
Aramid fabric is used in a wide range of applications, including:
Aerospace industry: Aramid fabric is used in aircraft components and spacecraft due to its lightweight and high strength.
Military and defense: Aramid fabric is used in body armor, helmets, and vehicle armor due to its high tensile strength and abrasion resistance.
Automotive industry: Aramid fabric is used in tires, belts, and hoses due to its heat resistance and durability.
Protective clothing: Aramid fabric is used in flame-resistant clothing for firefighters, industrial workers, and military personnel.
Sports equipment: Aramid fabric is used in sports equipment such as racing sails, tennis strings, and bicycle tires due to its high strength and durability.
With the rapid development of the national economy, the application of aramid fiber is gradually expanding, the demand is increasing day by day, in China, the aramid fiber industry has entered a stage of rapid development, but can scale up the production of aramid fibers manufacturers are concentrated in only a few enterprises, the demand for aramid fibers can not be met, most of them rely on imports. Vigorously develop aramid fiber to ensure domestic demand is the development of high-performance fibers to meet the national defense, military and civil important means. At the same time, China has also promulgated a series of policies and regulations to promote the development of aramid fibers, as the state encourages the development of high-tech products, the development of aramid fibers in the next few years the pace will gradually accelerate.
Changzhou Kingcaon Printing & Dyeing Co., Ltd. is specialized in dyeing and finishing of aramid and other essential flame retardant fabrics. Changzhou Kingcason Printing and Dyeing Co., Ltd. is the only professional factory in China that specializes in the whole roll dyeing of aramid fabric. And has a patent for the invention of aramid dyeing carrier research and development, the invention of the carrier applied to aramid fabrics, will make the cloth color more bright (breakthrough traditional aramid dyeing color light dull problem), the production process is odorless, environmentally friendly and safe water treatment does not have any impact on the wearer's health without any harm. Kingcason's airflow dyeing machines have dye bath ratios as low as 1:3, and airflow dyeing machines save water and steam (low overall energy consumption). This is also popular with environmental enthusiasts.
Then here we will also popularize the difference between aramid dyed yarn and piquant dyeing:
Aramid Dyeing: Aramid yarns are dyed before being woven into fabrics.
Aramid dyeing: the original color of aramid yarn is woven into cloth and then dyed.
The difference between them is: aramid dyed yarn has a long production cycle, low production rate, and it is difficult to correct the problem of dyed yarn color or cloth surface. The color of aramid dyeing is bright, the sunlight fastness can reach more than grade 3, the finished product can be color corrected or dyed, the production cost is lower than the dyeing, the production cycle is shorter, and the production is more flexible.
