2008 Annual Report 4.Accomplishments 1. Economically Fabricated Cotton-Rich FR Mattress Pads We have been able to fabricate cotton-rich nonwoven pads with Flame Retardant (FR) properties. These FR Cotton-based pads pass the California standard tests for mattress materials. By an optimized use of combination of FR fibers and chemical treatment of cotton, FR properties are accomplished at a low cost. NP 306, Component 2, Problem Area a. 2. Flame and stain resistant cotton Large scale samples of nitro-benzyl cellulose (substituted cotton) and amino-benzyl cellulose (cotton) were prepared and characterized by specialized techniques such as FT-IR (fourier transform infrared, CP/MAS 13C NMR (cross-polarization/magic-angle spinning 13 carbon nuclear magnetic resonance), and TGA (thermogravimetry analysis). These reactions serve as models for future heterogeeous cotton fiber finishing technology with applications in wash fast flame and stain resistance.
