纯棉织物是以棉花为原料,通过织机,由经纬纱纵横沉浮相互交织而成的纺织品。目前按照实际加工的棉花来源又区分为原生棉织物和再生棉织物。 ① 本色白布:普通布面、细布、粗布、帆布、斜纹坯布、原色布。 ② 色布:有硫化蓝布、硫化墨布、士林蓝布、士林灰布、色府绸、各色卡叽、各色华呢。 ③ 花布:是印染上各种各样颜色和图案的布。如:平纹印花布、印花斜纹布、印花哔叽、印花直贡。 ④ 色织布:它是把纱或线先经过染色,后在机器上织成的布如条格布、被单布、绒布、线呢、装饰布等。 用火烧,灰呈现灰白粉末状,有烧纸的味道,说明是纤维素纤维,如棉、人造棉、麻都是这样。但人造棉比棉软,麻比棉硬。

求采纳

鉴别服装面料成分的简易方法是燃烧法。做法是在服装的缝边处抽下一缕包含经纱和纬纱的布纱,用火将其点燃,观察燃烧火焰的状态,闻布纱燃烧后发出的气味,看燃烧后的剩余物,从而判断与服装耐久性标签上标注的面料成分是否相符,以辨别面料成分的真伪。
一、棉纤维与麻纤维
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。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烬。

二、毛纤维与真丝
毛遇火冒烟,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。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。

三、锦纶与涤纶
锦纶学名聚酰胺纤维,近火焰即迅速卷缩熔成白色胶状,在火焰中熔燃滴落并起泡,燃烧时没有火焰,离开火焰难继续燃烧,散发出芹菜味,冷却后浅褐色熔融物不易研碎。涤纶学名聚酯纤维,易点燃,近火焰即熔缩,燃烧时边熔化边冒黑烟,呈黄色火焰,散发芳香气味,烧后灰烬为黑褐色硬块,用手指可捻碎。

四、腈纶与丙纶
腈纶学名聚丙烯腈纤维,近火软化熔缩,着火后冒黑烟,火焰呈白色,离火焰后迅速燃烧,散发出火烧肉的辛酸气味,烧后灰烬为不规则黑色硬块,手捻易碎。丙纶学名聚丙烯纤维,近火焰即熔缩,易燃,离火燃烧缓慢并冒黑烟,火焰上端黄色,下端蓝色,散发出石油味,烧后灰烬为硬圆浅黄褐色颗粒,手捻易碎。

五、维纶与氯纶
维纶学名聚乙烯醇缩甲醛纤维,不易点燃,近焰熔融收缩,燃烧时顶端有一点火焰,待纤维都融成胶状火焰变大,有浓黑烟,散发苦香气味,燃烧后剩下黑色小珠状颗粒,可用手指压碎。氯纶学名聚氯乙烯纤维,难燃烧,离火即熄,火焰呈黄色,下端绿色白烟,散发刺激性刺鼻辛辣酸味,燃烧后灰烬为黑褐色不规则硬块,手指不易捻碎。

六、氨纶与氟纶
氨纶学名聚氨基甲酸酯纤维,近火边熔边燃,燃烧时火焰呈蓝色,离开火继续熔燃,散发出特殊刺激性臭味,燃烧后灰烬为软蓬松黑灰。氟纶学名聚四氟乙烯纤维,ISO组织称其为萤石纤维,近火焰只熔化,难引燃,不燃烧,边缘火焰呈蓝绿碳化,熔而分解,气体有毒,熔化物为硬圆黑珠。氟纶纤维在纺织行业常用于制造高性能缝纫线。

七、粘胶纤维与铜铵纤维
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。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。

注意事项
要小心不要烧到手或者把衣服烧坏。
