The viscose rayon fiber “DFG” in which flame retardant agent is incorporated.
Since it is a viscose rayon fiber which has the flame retardant element in mixture, it excels in flame retardant durability, and further has soft hand and feelwith moisture-retaining capability of regular viscose rayon fiber. In addition, it
is eco-friendly because it is made out of cellulose having biodegradability.

1

Adding flame retardance tocellulose●DFG has excellent hygroscopicity and water absorbency like regular viscose rayon fiber.
●DFG has flame retardance while maintaining its
unique texture and feel of regular viscose rayon fiber.
●DFG is excellent in the durability of flame retardance,and maintains its performance even after washing.
●Limiting oxygen index (LOI), an indicator of flame
retardancy is 28 or more. (Test method is JIS L1019 E)

3

Combustion gas●DFG does not contain halogen, and further does not generate poisonous halogenide gasses during combustion.

2

Thermal characteristic●DFG produces no shrinkage and no melt drip when incontact with heat of flame, therefore it does notdeform and shrink due to heating like synthetic fibers.
●DFG demonstrates flame retardance by carbonizing
action. Also, unlike molten fibers such as polyester, it
does not melt down and stick to the skin whenburned. (Please check aptitude, when you mix with other materials)

4

Disposal method is easy.

●Since it is a cellulose, DFG can be discarded likecotton. Special processing is unnecessary.

●DFG generates less smoke when combustion comparedwith other fibers, and cyanide gasses are not generated.

Other side

Testing with DFG®
● DFG enables shape retention through carbonization.
● Since it is not a molten fiber, there is no adhesion ofmolten material to the skin.

● Flame retardant polyester melts, and gets a hole.
● Hot molten material may adhere to the skin.

● Standard : JIS L 1091 A-1 method

Sample: 200 g/m 2 spunlace

[Handling and cautions]•Reconfirm the performance, if using 100% DFG or mixing with other materials. •It does not assure to protect the body from burn, etc. •Use the product only after understanding the intended
use, conditions, and environment. •Store indoors at 40℃ or below, out of direct sunlight. There is a possibility of discoloration. •Do not use fire or strong oxidizing agents in the vicinity of thestorage area. •Do not handle the product in areas where exhaust gases (NOx, SOx, etc.) are generated. There is a possibility of discoloration.
