Flame retardant nonwoven fabric, also known as flame-retardant non-woven cloth, is a type of fabric that does not require spinning or weaving. It is a thin sheet, web, or pad made by rubbing, hugging, or bonding fibers arranged in a directional or random manner, or a combination of these methods. Its flame retardant mechanism primarily involves the use of flame retardants, which are additives commonly used in polyester plastics, textiles, etc. They are added to polyester to increase the ignition point of the material or prevent it from burning, thereby achieving the intention of flame retardancy and improving the fire safety of the material.
What are the differences between it and non-woven fabric?
Different materials
The raw materials for flame-retardant non-woven fabrics and ordinary non-woven fabrics are both polyester and polyamide. However, during the processing of flame-retardant non-woven fabrics, flame retardants and harmless compounds such as aluminum phosphate are added to improve their flame-retardant properties.
However, ordinary non-woven fabrics usually use synthetic fibers such as polyester and polypropylene as raw materials, without special flame retardant substances added, so their flame retardant performance is weak.
Different fire resistance performance
The fire resistance of flame-retardant non-woven fabric is better than that of ordinary non-woven fabric. When encountering a fire source, flame-retardant non-woven fabric can prevent the spread of fire and greatly reduce the probability of fire occurrence. Flame retardant non-woven fabric has better heat resistance than non-woven fabric. According to surveys, ordinary non-woven fabric has significant shrinkage when the temperature reaches 140 ℃, while flame retardant non-woven fabric can reach a temperature of around 230 ℃, which has obvious advantages. However, ordinary non-woven fabrics have weak flame retardancy and are prone to fire spread after a fire occurs, increasing the difficulty of the fire.
Different uses
Flame retardant non-woven fabric is mainly used in places with high safety requirements, such as electricity, aviation, rail transit, civil buildings, etc. However, ordinary non-woven fabrics have a relatively limited range of applications, mainly used in fields such as healthcare, hygiene, clothing, shoe materials, and home furnishings.
Different production processes
The production process of flame-retardant non-woven fabric is complex, requiring the addition of flame retardants and multiple treatments during the processing. Ordinary non-woven fabrics are relatively simpler.
Concusion
In summary, there are certain differences between flame-retardant non-woven fabrics and ordinary non-woven fabrics in terms of materials, fire resistance, applications, and production processes. Compared to ordinary non-woven fabrics, flame-retardant non-woven fabrics have better safety and fire resistance, and can be widely used in places with high safety requirements.
