Is viscose non woven fabric flame - retardant?
As a supplier of viscose non woven fabric, I often encounter questions from customers regarding the flame - retardant properties of our products. This is a crucial aspect, especially in industries where safety and compliance with fire regulations are of utmost importance. In this blog, I will delve into the topic to provide a comprehensive understanding of whether viscose non woven fabric is flame - retardant.
Understanding Viscose Non Woven Fabric
Viscose non woven fabric is made from viscose fibers, which are regenerated cellulose fibers. It is produced through a non - weaving process, which means the fibers are bonded together rather than being woven like traditional textiles. This fabric has many desirable properties, such as softness, absorbency, and good drapability, making it suitable for a wide range of applications including hygiene products, medical supplies, and home textiles.

Natural Flame - Retardant Characteristics of Viscose
By nature, viscose fibers are not highly flame - retardant. Viscose is a cellulose - based fiber, and cellulose is a combustible material. When exposed to an open flame, viscose non woven fabric will burn. It has a relatively low ignition temperature and can sustain combustion, which is a concern in environments where fire safety is a priority.
However, it's important to note that the burning behavior of viscose non woven fabric can be influenced by several factors. For example, the density of the fabric plays a role. A denser viscose non woven fabric may burn more slowly compared to a lighter - weight one because there is more material to consume during the combustion process. Also, the presence of other additives or finishes on the fabric can affect its flammability.
Flame - Retardant Treatments for Viscose Non Woven Fabric
To address the fire safety concerns, manufacturers can apply flame - retardant treatments to viscose non woven fabric. These treatments work by either creating a barrier on the surface of the fabric to prevent oxygen from reaching the combustible fibers or by releasing chemicals that interfere with the combustion process.
There are different types of flame - retardant treatments available. One common method is the use of chemical additives during the manufacturing process. These additives can be incorporated into the viscose solution before the fibers are formed or applied as a finish on the surface of the non woven fabric. Another approach is to use a coating that contains flame - retardant agents.
Testing the Flame - Retardant Properties
To ensure that the treated viscose non woven fabric meets the required fire safety standards, it needs to undergo rigorous testing. There are various international and national standards for evaluating the flammability of textiles, such as the ASTM D6413 standard in the United States and the EN 13772 standard in Europe.
These tests typically involve exposing the fabric to a controlled flame source for a specified period and measuring parameters such as ignition time, flame spread rate, and after - glow time. Only fabrics that pass these tests can be considered flame - retardant and suitable for use in applications where fire safety is critical.
Applications of Flame - Retardant Viscose Non Woven Fabric
Flame - retardant viscose non woven fabric has a wide range of applications. In the automotive industry, it can be used for interior trim such as seat covers and headliners to meet the strict fire safety regulations. In the construction industry, it can be used as insulation materials or wall coverings. Spunlace Viscose Non Woven Fabric
In the healthcare sector, flame - retardant viscose non woven fabric can be used for surgical gowns and drapes to prevent the spread of fire in case of an accident in the operating room. It is also used in home furnishings such as curtains and upholstery to enhance the fire safety of living spaces.
