How to distinguish between silk fabrics and chemical fiber fabrics What is the phenomenon

The old people all said to burn it with fire and smell it. The composition of silk is protein, and the smell of roasted pork hair is like roasted pork hair (this is a very figurative metaphor).

1. Observe the luster: The luster of real silk is soft and uniform, bright but not dazzling. Although the luster of rayon fabric is also bright, it is not soft and pleasing to the eye.

Although the luster of polyester yarn is uniform, there is glitter or bright silk. Nylon silk fabrics have a poor luster, as if coated with a layer of wax.

2. Hand touch feeling: when hand touches silk fabrics, there is a feeling of pulling hands, while other chemical fiber products do not have this feeling. The rayon fabric is smooth and soft, but not crisp. Cotton silk weaving hands are hard but not soft to the touch.

3. Carefully inspect the creases: when the hand pinches the silk fabric and then releases it, there is no crease because of its good elasticity. Rayon fabrics have obvious creases after being released, and the creases are difficult to restore to their original shape. Although nylon silk has creases, it can also slowly return to its original shape, don't be fooled by its illusion.

4. Test fiber tensile force: extract a few fibers at the edge of the fabric, wet it with your tongue, if it is easy to break in the wet, it means that it is rayon, if it is not pulled off in the wet, it is silk, if the fiber is very strong in the dry and wet state, it is nylon yarn or polyester yarn that is not easy to break.

5. Listen to the sound of rubbing: because the silk is protected by sericin and resistant to friction, the dry silk fabrics will make a sound when they rub against each other, commonly known as silk or silk, while other chemical fiber products have no sound.

1. The ingredients are different.

Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc. Silk is known as the "Queen of Fibers" and has been favored by people throughout the ages for its unique charm, and silk belongs to protein fibers.

Chemical fiber fabric is a new type of clothing developed in modern times, and there are many types.

2. The characteristics are different.

Silk has good moisture absorption, breathability, skin care and health care effects. Silk is a protein fiber, and silk carpets woven with silk as raw materials have good ultraviolet absorption.

Chemical fiber advantages: strong and durable, easy to care for, with anti-wrinkle and iron-free characteristics, can be industrialized large-scale production, unlike natural fiber filial piety and poor maintenance occupies land, processing is time-consuming and laborious, and the output is limited.

You can burn it, silk has the smell of burning hair, polyester is the smell of chemical fiber burning, and the ashes of polyester are hard balls after burning, and the ashes of silk will break when you press it.
