In the workplace, people may be exposed to high temperatures or flames. In this case, appropriate protective clothing should be given to them. Therefore, such protective clothing should be properly selected. The purchaser should know this protection. The expected role of clothing. The purpose of this protective suit is to act as a fire shield when exposed to a flame, a barrier between the wearer and the flame.

Isolation of heat from flames and heat sources. It should also protect the wearer from the heat and flames of the wearer. The protective effect of such protective clothing for the wearer should be consistent with the potential hazards faced by them during exposure, escape, and the service life of the protective suit. They should not burn, melt or break when in contact with the flame. . It should also provide mechanical protection against tearing, abrasion, and seaming, as well as protection against weather changes and chemicals as intended.

Once the failure of protection has fatal consequences, the source of the product is particularly critical. It must be continuously inspected and tested to ensure that the protective clothing purchased by the manufacturer, the purchaser and the user is indeed “suitable for the purpose”. This means that you can expect the desired results in the expected environment.

The final production of protective clothing is a result of crossing the “value chain”; that is, a series of activities in the production process in which the product passes through each stage of the production process and gradually transforms the raw materials into finished products at each stage. Some organizations that produce quality products have a good reputation, and they strictly enforce performance and quality standards from the beginning to the end of the value chain in order to deliver finished products to users.

(1) Fiber production process:

Fiber is an essential element of fabrics and other textile structures. The meta-aramid in the chemical family is a fiber widely used in high temperature/flame-protected garments, which is characterized by high strength, especially high temperature/flame resistance. Well-known meta-aramid fibers for high temperature/flame-protective garments include Kermel, Conax, Conex, and Nomec Nomex (Nomex).

(2) Yarn making process:

The original form of fiber cannot be used in protective clothing. In order to achieve this, they must be converted into yarns. The process of forming the yarn is spinning, or winding the fibers together to form the yarn. Yarns are used to woven into fabrics and can also be used to make threads that sew together fabrics to form protective clothing. The meta-aramid fiber can be spun into a meta-aramid yarn.

(3) Fabric making process:

The transition from yarn to fabric is a physical change. When producing high temperature/flame protective clothing fabrics from flame retardant fibers, other factors should be considered in accordance with the ultimate use of protective clothing. These factors include structure, weight, comfort, strength, elasticity and color. There are also some factors that need to be considered, such as waterproof/anti-chemicals, visibility and anti-static. Blending fabrics made from meta-aramid yarns with other special high-quality fibers provides these desired functions in the fabric and is used in protective clothing in the second phase of the value chain.
