　　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(jīng)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(biāo)簽內(nèi)容是一致的,識別結(jié)構(gòu)內(nèi)容的真實性。
　　In kindergarten, there is a thread of warp and weft under the smoke. The cloth is ignited by fire.

　　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. After burning, the ashes are mostly smooth black spherical particles, and the fingers are broken when it is pressed. When the silk meets the indentation, the fire slows down, hisses, and gives off the smell of burnt hair. After forming a dark brown ball, it burns to ashes, and the hand twists and breaks.
　　聚酰胺及聚酯聚酰胺學(xué)名聚酰胺纖維，靠近火焰或卷曲熔融成白色膠體，迅速熔滴而閃閃發(fā)光，在火焰中燃燒無火，留下火焰燃燒難，散發(fā)出芹菜味，米色熔融材料冷卻后不易粉碎。滌綸纖維學(xué)名滌綸，易引燃，靠近火焰即收縮、熔化、燃燒時冒煙，火焰呈黃色，氣味芳香，燃燒后灰燼為深褐色塊狀，可用手指捻捻。
　　Polyamide and polyester polyamide, the scientific name of polyamide fiber, close to the flame or curl and melt into white colloid, quickly melt and sparkle, burn in the flame without fire, leaving the flame burning hard, sending out the smell of celery, the beige melting material is not easy to crush after cooling. 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(xué)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(xué)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(lán)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(jīng)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(xué)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(xué)名氯綸PVC纖維，不易燃燒，遠(yuǎn)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(lán)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。
