人们离不开纺织品,纺织品的原料是纤维。纤维柔软且有弹性,并具有一定的抗拉伸和耐磨擦等性能,经加工后可制成各种各样的织物。纺织纤维按其来源可分为天然纤维和化学纤维两大类。天然纤维包括植物纤维和动物纤维。棉花、大麻、黄麻、亚麻等都属于植物纤维;羊毛、兔毛、羊绒、蚕丝等都属于动物纤维。化学纤维主要包括人造纤维和合成纤维。那么,如何鉴别天然纤维和化学纤维呢?主要方法有感官鉴别法、燃烧法、显微镜观察法、药品检验法等。其中显微镜观察法和药品检验法适用于专职检验人员,做为一般消费者,只要掌握了前两
People can not do without textiles, textile raw materials are fiber. Soft and flexible fibers, and has some resistance to tensile and abrasion properties, after processing can be made into a variety of fabrics. According to their sources of textile fibers can be divided into two categories of natural fibers and chemical fibers. Natural fibers include plant fibers and animal fibers. Cotton, marijuana, jute, linen, etc. belong to plant fibers; wool, rabbit fur, cashmere, silk and so on belong to animal fibers. Chemical fibers include man-made fibers and synthetic fibers. So, how to identify natural fibers and chemical fibers? The main methods are sensory identification method, combustion method, microscopy, drug testing method. One microscope observation and drug testing method for full-time inspectors, as an average consumer, as long as the first two
