The difference between flame-retardant non woven fabric and non woven fabric is that flame-retardant non-woven fabric adopts special processes and adds flame retardants in production, making it have some special properties. What are the differences between it and nonwoven fabric?
Different materials
Flame retardant non-woven fabrics are generally produced using pure polyester as raw material, with the addition of some harmless compounds such as aluminum phosphate, which can 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 performance
Flame retardant non-woven fabric has good flame retardant properties, including high temperature resistance, anti-static, and fire resistance. In the event of a fire, the burning area can be quickly extinguished, greatly reducing fire damage. 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.
Flame retardant non-woven fabric has better heat resistance than polypropylene non-woven fabric and has obvious thermal shrinkage. According to surveys, the latter 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.
The anti-aging cycle is higher than that of polypropylene non-woven fabrics. Polyester is used as raw material, which is resistant to moth, abrasion and ultraviolet rays. All the above characteristics are high polypropylene non-woven fabrics. Compared with polypropylene and other non-woven fabrics, it has excellent properties such as non absorbent, water-resistant, and strong breathability.
Different use
Flame retardant non-woven fabric has good flame retardant properties, such as high temperature resistance, anti-static, and fire resistance, and is widely used in fields such as construction, aviation, automobiles, and railways. Ordinary non-woven fabric can be used for daily necessities such as medical, hygiene, clothing, shoe materials, home, toys, home textiles, etc.
Different production processes
The production process of flame-retardant nonwoven fabric is complex, requiring the addition of flame retardants and multiple treatments during the processing. Ordinary non-woven fabrics are relatively simpler.
Price difference
Flame retardant non-woven fabric: Due to the addition of flame retardants and special production processes, its cost is relatively high, so its price is relatively expensive compared to ordinary non-woven fabric.
Ordinary non-woven fabric: Low cost, relatively cheap price, suitable for occasions that do not require special fire protection requirements.
Conclusion
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.
The flame retardant principle of flame-retardant non woven fabric
Flame retardant non-woven fabric is more heat-resistant than other non-woven fabrics, with a higher melting point and better sealing performance. The editor would like to make up for two points you mentioned. Firstly, optical fibers are included in additives, and secondly, non-woven fabric surface coatings contain flame retardants.
1、 The flame retardant function of flame retardants is added to fibers through polymerization, blending, copolymerization, composite spinning, grafting techniques, and other properties of polymers, making the fibers flame retardant.
2、 Secondly, the flame retardant coating is applied to the surface of the fabric or penetrates into the interior of the fabric after finishing.
With the improvement of rice materials and nanotechnology, the cost of textiles is low and the effect is sustained, while the softness and feel of textiles remain basically unchanged, reaching the international first-class level.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
