Fiber identification with a burning test [12] Fiber type Burning test Cellulose fibers (Cotton, Linen, Rayon) It burns constantly with light grey smoke, doesn't melt or shrink, smells like burning paper, and leaves grey feathery ash. Protein (Silk, and Wool)
[1] Fiber analysis does not follow any officially laid-down procedure. The most common use of fiber analysis is microscopic examination of both longitudinal and cross sectional samples. While this is the most common method of undertaking fiber analysis, others do exist. These include the burning and solubility methods.
Wood fibres can be used as a substrate in hydroponics. Wood wool (i.e. wood slivers) have been a substrate of choice since the earliest days of the hydroponics research. [4] However, more recent research suggests that wood fibre can have detrimental effects on "plant growth regulators". [5] [non-primary source needed]
Take wood as an example. Finely divided wood dust can undergo explosive flames and produce a blast wave. A piece of paper (made from wood) catches on fire quite easily. A heavy oak desk is much harder to ignite, even though the wood fibre is the same in all three materials.
MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. [4] The density is typically between 500 and 1,000 kg/m 3 (31 and 62 lb/cu ft). [ 5 ] The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing.
InsideWood is an online resource and database for wood anatomy, serving as a reference, research, and teaching tool. Wood anatomy is a sub-area within the discipline of wood science. [1] [2] This freely accessible database is purely scientific and noncommercial.

This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test. The result is derivation of a Flame Spread Index ( FSI ), [ 2 ] which is a non-dimensional number which is placed on a relative scale in which asbestos-cement board has a value of 0, and red oak wood has 100.
