In the previous issue, we talked about a lot of knowledge about socks, focusing on the various raw materials used to produce socks. Today, we will continue to teach you how to distinguish the raw materials of socks.
For professionals with many years of experience in the industry, it is very easy to distinguish the raw materials of socks. They can basically tell the raw materials and their production process at a glance. However, for most ordinary people, it is not clear. Zhang Weichao’s sock industry teaches you the simplest method, which is to use fire. The following are the combustion characteristics of various raw materials.
Cotton material: burns immediately upon contact with fire, continues to burn after leaving the flame, with a smell of burning paper and a small amount of gray white.
Wool material: It burns slowly after being ignited, and sometimes goes out on its own after leaving the fire, with a foul odor and a grayish white powder.
Brocade cotton material: Melts and contracts when exposed to flames, burns slowly, and extinguishes on its own after leaving the fire. It has a special odor and a loose and brittle black ash.
Polyester material: Near the flame melting and shrinking, slowly burning, leaving the flame to continue burning, fragrant odor, very hard black beads.
Acrylic material: Near flame melting and shrinking, emitting black smoke during combustion, with a unique odor that drives it to become hard and amorphous.
Nylon: Near flames: Melting shrinkage; Contact with flames: melting, smoking; Leaving the flame: self extinguishing; Odor:
Amino flavor; Residue characteristics: Hard light brown transparent round beads.
Polyester: Near flame: Melting shrinkage; Contact with flames: melting, smoking, slow burning; Leaving the flame: Continue to burn, sometimes self extinguishing; Residue characteristics: hard black round beads.
Alright, the above is the simplest way for non sock industry professionals to distinguish raw materials for socks. Have you learned it? I will teach you more useful sock knowledge about Zhang Weichao’s sock industry.
