US standard fire retardant nonwoven spunbond fabric

Due to the continuous development of urban construction and transportation facilities, the amount of non-woven fabrics used for indoor and cabin decoration, such as curtains, curtains, wall coverings, felt, and bedding, is increasing day by day. However, at the same time, fires caused by fires of such products have also occurred one after another. Developed countries around the world had already put forward flame retardant requirements for textiles as early as the 1960s, and formulated corresponding flame retardant standards and fire regulations. The Ministry of Public Security of China has formulated fire safety regulations, which clearly stipulate that curtains, sofa covers, carpets, etc. used in public entertainment venues must use flame-retardant materials. Therefore, the development and application of flame-retardant nonwoven products in China have developed rapidly, showing a good development trend.

The flame retardant effect of non-woven fabrics is achieved by adding flame retardants. In order for flame retardants to be applied on non-woven fabrics, they must meet the following conditions:

(1)  Low toxicity, high efficiency, and durability, which can make the product meet the requirements of flame retardant standards;

(2)  Good thermal stability, low smoke generation, suitable for the requirements of non-woven fabrics;

(3) Not significantly reducing the original performance of non-woven fabrics;

(4)  Low price is beneficial for reducing costs.

Flame retardant finishing of non-woven fabrics: Flame retardant finishing is achieved by fixing flame retardants onto conventional non-woven fabrics through adsorption deposition, chemical bonding, non-polar van der Waals force bonding, and bonding. Compared with fiber modification, this method has a simpler process and less investment, but it has poor washing performance and has a certain impact on the appearance and feel of non-woven fabrics. Flame retardant finishing can be carried out by dipping and spray.

Flame retardant non-woven fabric products mainly have the following applications.

(1) Used for indoor and cabin decoration, such as curtains, curtains, carpets, seat covers, and interior paving materials.

(2) Used as bedding, such as mattresses, bed covers, pillows, seat cushions, etc.

(3) Used as wall decoration and other flame retardant sound insulation materials for entertainment venues.
