Improvement of Burning Properties on the Cotton/polyester/lacra Blend Fabric with Nano Silicone Material in Nano Silicone

In this research, we established a modified 45 flammability test for cotton blend material to measure the flammability of nanosilicone softener treated-cotton blend material. The wet pick-up was about 150±10%. b) The specimens were tested in the cross direction and nine specimens were measured. The average percent weight loss of the untreated cotton blend nonwoven is only 0.9%. The percent weight loss of treated sample is much higher than that of the untreated and this increased with the softener concentration. The treated samples show much higher weight loss and burning area than those that are untreated.There are few publications elucidating the antagonistic defeat of the FR process for cotton blend observed with commercial finishes. TGA shows that the treatment with nanosilicone softener increases the thermal stability of cotton blend in air before the maximum decomposition rate temperature and increases the residue of cotton blend. This study will both quantify the effect and fully characterize the mechanisms by which siloxanes affect the chemical and physical processes that occur during the degradation and burning of cotton blend and then will investigate approaches to mitigating these effects.
