- the textile specimens were suspended vertically. A Bunsen burner flame of height four cm was applied for 10 sec under each textile specimen. The fire tests investigated whether visible flames emerged from the specimen during the test. Once the flame had been removed, any ignition and/or further smoldering of the textiles was observed. The height of the carbonized area was measured in millimeters from the lowest edge of the specimen to the upper limit of the carbonized area.
- Pieces of cotton fabric (100*115 mm, weight per unit area 140 g/qm) are immersed in accordance with Example BB of WO 98/24604 in an impregnating solution composed of 1.35% by weight of dicyandiamide, 11.6% by weight of monoammonium phosphate, 1.87% by weight of phosphoric acid, 0.11% by weight of magnesium hydroxide, 0.13% by weight of ammonium carbonate, 0.04% by weight of additive, and 85% by weight of water, and soaked.
- the impregnating solution comprises 15% by weight of active substance. After the soaking process, the pieces of fabric are squeezed dry and dried at 110° C. in a drying cabinet.
