Of the pure wool handmade carpet method has a lot of kinds, the overall generalizations can be for two ways: one is a more direct visual senses identification method, the other is a debate other by combustion method to achieve.
I. the sensory identification method.
This method does not need to use any equipment and other objects, by their long-term work experience and their own ability, according to the manual wool carpet handle and suede to identify.
Because acrylic carpets, commonly known as fake wool carpet, acrylic fiber materials with unique excellent characteristics of similar to wool fiber, make people so it is difficult to distinguish between wool carpet and acrylic latex-back carpet.
But as long as they are carefully observed and carefully compared, they differ.
Intuitively, the wool carpet is softer than the nylon carpet, and is more flexible than the big one, and the color is softer.
The burning method.
From manual wool carpet inside take out a couple of wool yarn, the method of using combustion to identify, the burning of wool, foaming, while smoking with hair smell at the same time, ash, glossy black will be brittle block.
Acrylic combustion, melting, while slow combustion flame is white, and bright and strong, slightly smoky, have fishy smell, gray to white balls, brittle and easily broken.
Polyamide combustion, while slow combustion, melting when the white smoke, fire small and blue, with the fragrance of celery, ash for beige lump, not easy to crush.
