Feb 17, 2020

Visual method: The silk fabric has a pearl-like luster and is very soft. The synthetic silk artificial silk looks bright and dazzling.

Hand touch method: Silk has a slight shaving feel, and the fabric is folded in half and rubbed with a "silk whistle" sound. The simulation silk feels a bit "rough", which is quite stiff.

Burning experiment: Silk is very flammable, and it is difficult to see open flames. At the same time, there is gray smoke, a smell of burning hair, and the edges of the flames are brown and black, and some are shiny. They are granules of different sizes and can be crushed with a pinch.

The artificial silk is non-flammable, there is no open flame, and it emits very small gray smoke, which will drip white waxy oil while burning. Has a less intense pungent odor. The edges of the fire will be tangled together, brown and black, and a little further away will be white (the effect is similar to polyester cotton). It is rubbery, hard and firm. Interpretation: Artificial silk is just like silk Wang Jian said. Silk fabrics generally refer to silk, including mulberry silk, tussah silk, castor silk, and cassava silk. They are protein fibers and have good thermal insulation, moisture absorption, moisture dissipation, and breathability. Comfortable. The artificial silk is a special process and special finishing of polyester fiber filaments. It looks like silk in appearance, gloss, and feel. It is a synthetic fiber. It has excellent properties that silk does not have.
