一種識別幼兒園服裝面料成分的簡單方法:燃燒法。
A simple method to identify the components of kindergarten clothing fabric: combustion method.
在幼兒園是煙的下擺一縷經紗和緯紗,布用火點燃,觀察燃燒火焰的狀態(tài),聞燒傷后的織物紗線的氣味,看燃燒后的殘余,因此判斷和幼兒園把織物耐久性標簽內容是一致的,識別結構內容的真實性。
In kindergarten, there is a thread of warp and weft under the smoke. The cloth is ignited by fire. Observe the state of the burning flame, smell the smell of the burnt fabric yarn, and see the residue after the burning. Therefore, judge that the content of the durability label of the fabric is consistent with that of the kindergarten, and identify the authenticity of the structural content.
棉、麻纖維幼稚園服裝面料成分鑒定:棉、麻纖維燃燒時火焰一近，燃燒迅速，火焰呈黃色，發(fā)出藍色煙霧。燃燒后，棉花有很少的粉末狀灰分，黑色或灰色，大麻會產生少量的灰分粉末狀灰分。
Identification of fabric composition of cotton and hemp fiber kindergarten clothing: when cotton and hemp fiber burn, the flame is close, burning quickly, the flame is yellow, emitting blue smoke. After burning, cotton has little powder ash, black or gray, hemp will produce a small amount of ash powder ash.
毛纖維和真絲毛在火中冒煙，燃燒時起泡，燃燒速度較慢，發(fā)出一股焦味頭發(fā)燃燒，燃燒后的灰燼多為光滑的黑色球狀顆粒，一壓即斷指。絲遇壓痕使火，燃燒速度減慢，發(fā)出嘶嘶聲，散發(fā)出燒焦頭發(fā)的氣味，形成深褐色的小球后燃燒成灰燼，手捻即斷。
The hair fiber and silk hair smoke in the fire. When it burns, it bubbles. The burning speed is slow. It gives off a burning smell of hair.

The scientific name of polyester fiber is polyester, which is easy to ignite. It shrinks, melts and smokes when it is close to the flame. The flame is yellow and smells fragrant. After combustion, the ash is dark brown block, which can be twisted by fingers.
丙烯和聚丙烯丙烯的學名為聚丙烯腈纖維，靠近火軟化融化后再冒煙，用大火燒成白色火焰，大火迅速燃燒后，散發(fā)出火種肉的苦味，燃燒后灰燼為不規(guī)則黑色塊狀，手捻易碎。聚丙烯的學名，聚丙烯纖維靠近火焰即收縮，易燃，燃燒緩慢而冒煙，火焰上部呈黃色，底部呈藍色，散發(fā)出油煙味，燃燒后的灰燼如堅硬的小黃褐色顆粒，經手捻后易碎。
The scientific name of propylene and polypropylene propylene is polyacrylonitrile fiber. It softens and melts near the fire and then smokes. It burns into a white flame with a large fire. After the fire burns rapidly, it gives off the bitter taste of the fire meat. After the fire, the ashes are irregular black blocks, and the hands are fragile. Scientific name of polypropylene: polypropylene fiber shrinks when it is close to the flame. It is flammable. It burns slowly and smokes. The upper part of the flame is yellow and the bottom is blue. It gives off the smell of oil smoke. The ashes after burning are like small hard yellow brown particles, which are fragile after being twisted by hand.
學名whalen和氯綸whalen聚乙烯醇甲醛纖維，不容易點燃，近火焰熔融收縮，頂部有少許火焰，燃燒為纖維混合膠化火焰，有濃濃的黑煙，有苦甜的氣味，燃燒后留下黑色小珠顆粒，可用手指壓碎。學名氯綸PVC纖維，不易燃燒，遠離火種即為撲滅，火焰呈黃色，底綠色白色冒煙，辛辣刺激酸澀，燃燒后灰燼為深褐色不規(guī)則塊狀，手指扭曲不易折斷。
Its scientific name is Whalen and chloro fiber Whalen polyvinyl formal fiber, which is not easy to ignite. It is near the flame melting and contracting. There is a little flame on the top. The flame is a mixed gelatinized flame of fiber, with thick black smoke and bitter sweet smell. After burning, it leaves small black beads, which can be crushed by fingers. Its scientific name is PVC fiber, which is not easy to burn. If it is far away from the fire, it will be extinguished. The flame is yellow, with green and white smoke at the bottom. It is spicy and sour. After burning, the ash is dark brown irregular block, and the fingers are not easy to break.
氨綸和氟烷氨綸，又稱聚氨基甲酸酯纖維，在火附近熔化和燃燒，火焰燃燒時呈藍色，離開火繼續(xù)熔化和燃燒，發(fā)出一種特殊的刺激性氣味，燃燒后的灰燼是柔軟而蓬松的黑色灰燼。
Spandex and halothane spandex, also known as polyurethane fiber, melt and burn near the fire. When the flame burns, it is blue, and continues to melt and burn away from the fire, giving out a special pungent smell. The ash after combustion is soft and fluffy black ash.
