First, what is flame retardant fiber yarn
Flame retardant fiber yarns are yarns made from fibers with flame retardant properties through the spinning process. These fibers are usually subjected to special chemical treatment or added flame retardants, so that when they come into contact with an ignition source, they can prevent or delay combustion, reduce the rate of spread of flame, and reduce the risk of fire.
Second, the types of flame retardant fibers
1. Natural flame retardant fiber
Wool: wool itself has certain flame retardant properties. It will form a carbonized layer when burning to prevent the further spread of flame.
Asbestos: Although asbestos has good flame retardant properties, it has been gradually eliminated due to its hazardous effects on human health.
2. Synthetic Flame Retardant Fiber
Aramid: Aramid fiber has high strength, high modulus and excellent flame retardant properties. It will not melt at high temperatures, but only carbonize, which can effectively protect the human body from flames.
Polyimide: This fiber has high temperature resistance, flame retardant, corrosion resistance, etc. It is widely used in aerospace, electronics and other fields.
Flame retardant polyester: By adding flame retardant to polyester fiber, it can be made to have good flame retardant properties. Flame retardant polyester fiber has the advantages of low cost and stable performance.
Third, the performance characteristics of flame retardant fiber yarns
1. Flame retardant properties
Flame retardant fiber yarn can stop the spread of flame to a certain extent and reduce the harm of fire. It can delay the burning time, providing more time for people to escape.
Different kinds of flame retardant fiber yarns have different flame retardant levels, which can be selected according to specific needs.
2. Mechanical properties
Flame retardant fiber yarn usually has high strength and modulus, which can meet the requirements of different fields.
It also has good abrasion resistance, corrosion resistance and anti-aging properties, which can prolong the service life.
3. Comfort
Some flame retardant fiber yarns, such as aramid fibers, have a soft handfeel and good breathability, comfortable to wear.
Flame retardant fiber yarn can also be blended with other fibers to improve its comfort and functionality.
IV. Application Areas
1. Firefighting clothing
Flame retardant fiber yarn is an important material for making firefighting clothes. It can provide effective protection for firefighters against flames and high temperatures.
Firefighting clothing usually adopts multi-layer structure, in which flame retardant fiber yarn is used as the outer layer, which has good flame retardant and waterproof performance.
2. Industrial protection
In petroleum, chemical, electric power and other industries, workers need to wear flame retardant coveralls to prevent the danger of fire and explosion. Flame retardant fiber yarn can be used to make these work clothes to provide safety.
Flame retardant fiber yarn can also be used to make industrial heat insulation materials, fire curtains and so on.
3. Household articles
Some home furnishings, such as curtains, carpets, bedding, etc., can also be made of flame retardant fiber yarn. This can improve the safety of home and reduce the occurrence of fire.
4. Aerospace
In the field of aerospace, flame retardant fiber yarn is widely used in aircraft interiors, spacecraft parts and so on. It can maintain stable performance under high temperature and high pressure environment, providing guarantee for flight safety.
V. Development Prospects
With the continuous improvement of people's awareness of safety, the market demand for flame retardant fiber yarn is also growing. In the future, flame retardant fiber yarn will develop in the direction of high performance, multi-functional and environmental protection. At the same time, with the continuous progress of science and technology, new types of flame retardant fiber yarn will also continue to emerge, bringing more safety for people's life and work.
