一、棉纤维与麻纤维：
燃烧特点：棉纤维与麻纤维都是刚近火焰即燃，燃烧迅速，火焰呈黄色，冒蓝烟。
Combustion characteristics: Both cotton fiber and linen fiber catch fire immediately when approaching the flame. They burn rapidly. The flame is yellow and emits blue smoke.
气味与灰烬区别：二者在燃烧散发的气味及烧后灰烬的区别是，棉燃烧发出纸气味，麻燃烧发出草木灰气味；燃烧后，棉有极少粉末灰烬，呈黑或灰色，麻则产生少量灰白色粉末灰。
Difference in smell and ashes: The difference between the two in terms of the smell emitted during combustion and the ashes after burning is that cotton burns with a paper smell, and linen burns with a plant ash smell. After burning, cotton has very little powder ash, which is black or gray, while linen produces a small amount of grayish-white powder ash.
二、毛纤维与真丝：
毛纤维燃烧特点：毛纤维遇火冒烟，燃烧时起泡，燃烧速度较慢，散发出烧头发的焦臭味，烧后灰烬多为有光泽的黑色球状颗粒，手指一压即碎。
Combustion characteristics of wool fiber: Wool fiber smokes when encountering fire. When burning, it bubbles. The burning speed is slow. It emits the scorched smell of burning hair. After burning, the ashes are mostly shiny black spherical particles that can be crushed with a finger press.
真丝燃烧特点：真丝遇火缩成团状，燃烧速度较慢，伴有咝咝声，散发出毛发烧焦味，烧后结成黑褐色小球状灰烬，手捻即碎。
Combustion characteristics of silk: Silk shrinks into a ball when encountering fire. The burning speed is slow. It is accompanied by a hissing sound. It emits the scorched smell of burning hair. After burning, it forms dark brown small spherical ashes that can be crushed by hand twisting.
三、粘胶纤维与铜铵纤维：
粘胶纤维燃烧特点：粘胶纤维易燃，燃烧速度很快，火焰呈黄色，散发烧纸气味，烧后灰烬少，呈光滑扭曲带状浅灰或灰白色细粉末。
Combustion characteristics of viscose fiber: Viscose fiber is flammable. The burning speed is very fast. The flame is yellow. It emits the smell of burning paper. After burning, there is little ash. It is a smooth and twisted ribbon-shaped light gray or grayish-white fine powder.
铜铵纤维燃烧特点：铜铵纤维俗名虎木棉，近火焰即燃烧，燃烧速度快，火焰呈黄色，散发酯酸味，烧后灰烬极少，仅有少量灰黑色灰。
Combustion characteristics of copper ammonium fiber: Copper ammonium fiber is commonly known as tiger wood cotton. It catches fire when near the flame. The burning speed is fast. The flame is yellow. It emits an ester sour smell. After burning, there is very little ash. There is only a small amount of grayish-black ash.
