2015-01-13 00:00:00

methods


Sense of touch. Pure wool fabrics usually feel smooth, long wool fabrics along with the feel of smooth, reverse hair tingling. And blended or pure chemical fiber, some less soft, some too soft and loose, and sticky feeling.


The colour and lustre. The color of pure wool fabric is soft and natural, bright and timeless. In contrast, blended or pure chemical fiber fabrics, or luster is darker, or have a sense of flash.


The elastic. Hold the fabric tightly by hand, then release it immediately to see how elastic the fabric is. Pure wool fabric rebound rate is high, can quickly restore to its original state, and blend or chemical fiber products, wrinkle resistance is poor, most of the more obvious wrinkle marks, or slow recovery.


Combustion identification. Take a bunch of yarn, use fire, pure wool fiber smell like burning hair, chemical fiber smell like burning plastic. The harder the particles are after combustion, the more chemical fiber components there are.


Single root identification. Hair under a microscope to see all the animals have scales, if is long hair fabrics as long as take a hair like above laid a few times will move up or down (to master this skill can take a hair from the first experiment), if it is a normal fabric, extracting a root yarn, cut 2 cm of the two paragraphs into one fiber under the hand rub four or five, they would not move.
