Inherent flame retardant (FR) fabrics are textiles that have been treated during the manufacturing process to make them resistant to fire without the use of chemical treatments. These types of fabrics are commonly used in various industries, including construction, transportation, and defense, due to their fire-resistant properties and durability.
The production process of inherent FR fabrics involves the use of FR fibers, such as aramid or modacrylic, which are blended with other fibers to create a durable and flame-resistant fabric. The blending process ensures that the FR properties of the fibers are evenly distributed throughout the fabric, providing consistent protection against fire.
When it comes to printing on inherent FR fabrics, there are several technical considerations that need to be taken into account to ensure that the fabric remains flame-resistant after printing. These include:
- Ink selection: It is essential to use inks that are compatible with the FR properties of the fabric. Incompatible inks can degrade the fabric’s FR properties, making it more susceptible to fire.
- Printing process: The printing process used must not interfere with the FR properties of the fabric. For example, high heat during printing can cause the fibers to shrink, reducing their effectiveness in resisting fire.
- Drying process: The fabric must be dried properly after printing to prevent any damage to its FR properties. Over drying or excessive heat can cause the fibers to shrink and become less effective in resisting fire.
- After-treatment: Some printing processes may require an after-treatment to enhance the fabric’s FR properties. This could include a special coating or treatment to restore the FR properties of the fabric after printing.
In conclusion, inherent FR printed fabrics are an excellent choice for industries that require flame-resistant textiles. However, it is important to consider the technicalities of the printing process to ensure that the fabric remains flame-resistant after printing. By selecting the right ink, using a compatible printing process, and proper drying and after-treatment, you can ensure that your inherent FR printed fabrics provide the highest level of protection against fire.
