Combustion characteristics of polyester thermal melt yarn and various fiber fabrics

As a new type of functional fiber in recent years, hot melt yarn has quickly become the new favorite of the textile industry. In order to let consumers better understand the difference between hot melt yarn and other textile fabrics, the editor briefly introduces the characteristics of textile fabrics under burning conditions.

Polyester hot melt yarn and nylon hot melt yarn

It is essentially a kind of fiber, but the two have different smells. The smell of real polyester hot melt yarn is more obvious when burning, and the smell is a bit smelly. Nylon hot melt yarn is bright and smooth, and has less smell.

Natural fibers such as wool and silk

Natural fibers mainly contain protein. It burns slowly and smokes slowly; it shrinks into a ball when burning, and is accompanied by a special burnt smell; the ash is in the shape of small balls and breaks when pressed.

Plant fibers such as cotton, linen, and bamboo

The main component of plant fiber is cellulose, which is easy to burn, produces yellow and blue flames, and has the smell of burning paper or grass. The ash is gray and easy to fly.

Synthetic fibers such as nylon, acrylic, chloroprene, and nylon

Nylon melts while burning, with no smoke or a little white smoke. The flame is small and blue. There is a smell of burnt celery, and the ashes are small light brown hard beads, which are not easy to crush; when polyester burns, it curls and melts while smoking, the flame is yellow-white, with an aromatic smell, and the ashes are small brown beads, which can be crushed by hand; acrylic burns slowly while melting, the flame is bright white, sometimes with a little black smoke, and has a fishy smell, and the ashes are small black beads, which are brittle and fragile; vinylon burns slowly and shrinks quickly, the flame is small, red, with black smoke and a special smell, and the ashes are small brown beads, which can be crushed by hand; chloroprene is difficult to burn, and when it is close to the flame, it shrinks and burns, and it will go out when it leaves the fire, with the smell of chlorine, and the ashes are black hard lumps; when polypropylene burns, it curls and melts, the flame is bright, blue, and has the smell of burning wax, the ashes are hard lumps, but can be crushed; glass fiber does not burn, does not change color when melted, and the ashes are natural color, in the shape of small glass beads.

Through the above combustion instructions, I hope to provide convenience for everyone to better distinguish textile fabrics.
