What does wool, nylon, cotton, chemical fiber, and silk taste like?

Wool and silk are both protein fibers, and they both smell of burning hair when burned, and the ashes are very small particles that are broken with a light twist of the hand.

Nylon, is the trade name of nylon, which generally includes nylon 6 and nylon 66

There are two kinds, when burning, first melt and shrink, and then burn slowly, and may automatically extinguish from the ignition source, with a celery smell and hard brown granules of ashes.

Pure cotton, which is cellulose fiber, burns quickly and has the smell of burning paper.

Chemical fibers, which are a large category of things, include the nylon above, and generally include polyester, which is the most versatile, as well as polypropylene.

Acrylic, spandex.

Wait a minute. Polyester: easy to ignite, near the flame that is melted and shrinked, black smoke is emitted while melting, yellow flame, emitting aromatic smell, the ashes are black-brown hard lumps after burning, and can be twisted with fingers.

Acrylic fiber is known as polyacrylonitrile fiber.

Near the fire softens and melts, black smoke rises after the fire, the flame is white, burns quickly after leaving the flame, emits the bitter smell of burning meat, and the ashes are irregular black hard lumps after burning, and the hand twist is fragile.

Polypropylene is polypropylene fiber.

Near the flame that is melted, flammable, from the fire burns slowly and emits black smoke, the upper end of the flame is yellow, the lower end is blue, exudes the smell of petroleum, the ash is hard round light yellow-brown particles after burning, and the hand twist is fragile.

Vinylon. Scientific name polyvinyl alcohol formaldehyde fiber, not easy to ignite, near the flame melt shrinkage, there is a little flame at the top of the burning, when the fibers are melted into a gelatinous flame to become larger, there is thick black smoke, emitting a bitter smell, after burning left black bead-like particles, can be crushed with fingers.

Wool burns with the smell of burnt hair; Nylon chemical fiber has the smell of burning plastic, and cotton and silk smell a bit like the smell of burning paper.

It could be silk or mulberry.

The smell of hair in the fire indicates that it is protein fiber. Silk and wool are protein fibers. It looks like cotton cloth, it is just a description, and it cannot be accurately judged without a physical object, but it can only tell you that it may be the silk spinning silk of mulberry silk or the banquet is mulberry silk.

They are all real silk sales, but they are different from the general silk hall teasing, which is silk staple fiber, that is, the silk is cut off, spun according to the processing method of cotton yarn, and then woven into silk cloth. The raw materials of silk spinning are finer and look closer to real silk; The raw material of silk is the raw material of uneven thickness close to the silkworm chrysalis and mixed with the debris of the silkworm pupae, and the woven silk cloth looks more like coarse cloth, with uneven pimples on the surface.
