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) It burns slowly, curls away from the flame, smells like burning hair and leaves ...
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. These methods are most commonly used to reveal the identity of the fiber.
For fiber: Fiber identification is a necessary test for determining fiber content and classifying products. The labelling of items with their fiber content percentage is a regulatory requirement. Using microscopy, solubility, and burn tests, fibers are distinguished from one another. [167]
Textile stabilization is a conservation method for fiber and yarn-based cloth intended to mitigate damage, prevent degradation and preserve structural integrity. Stabilization is part of a broad set of techniques in the field of conservation and restoration of textiles typically undertaken by a specialist or textile conservator .
The term fire-retardant as applied to organic (i.e., containing carbon) materials, is intended to refer to reduced fire hazard, as all will burn under certain circumstances. The tests used specified in building codes , such as NFPA 701, are more correctly flame resistance tests, which test a fabric's ability to resist ignition with the flame ...

Cellulose diacetate and cellulose triacetate are mistakenly referred to as the same fiber; although they are similar, their chemical identities differ. Triacetate is known as a generic description or primary acetate containing no hydroxyl group. Acetate fiber is known as modified or secondary acetate having two or more hydroxyl groups.
The burning of a solid material may appear to lose weight if the mass of combustion gases (such as carbon dioxide and water vapor) are not taken into account. The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and ...
