Smell the fragrance to recognize the fabric-the combustion method to identify various fabrics
According to the different chemical composition of the fiber, the combustion characteristics are also different, thus roughly distinguishing the major types of fibers. The comparison of the combustion characteristics of several common fibers is as follows:
(1) Cotton, hemp, viscose, cupra: close to the flame: no shrinkage and no melting; contact with flame: rapid burning; leaving the flame: continuing to burn; smell: smell of burning paper; residue characteristics: a small amount of gray black or gray white ash.
(2) Silk and wool fibers: close to the flame: curl and melt; in contact with the flame: curl, melt, and burn; leave the flame: slow burning and sometimes extinguish itself; smell: the smell of burnt hair; residue characteristics: loose and brittle black particles Or coke-like.
(3) Polyester fiber: close to the flame: melting; touching the flame: melting, smoking, slowly burning; leaving the flame: continue to burn, sometimes extinguished by itself; smell: special aromatic sweetness; residue characteristics: hard black round beads .
(4) Nylon fiber: near the flame: melting; contacting the flame: melting and smoking; leaving the flame: self-extinguishing; smell: amino smell; residue characteristics: hard light brown transparent round beads.
(5) Acrylic fiber: close to the flame: melting; contacting the flame: melting and smoking; leaving the flame: continuing to burn and emitting black smoke; smell: pungent; residue characteristics: black irregular beads, fragile.
(6) Polypropylene fiber: near the flame: melting; contacting the flame: melting and burning; leaving the flame: continuing to burn; smell: paraffin smell; residue characteristics: off-white hard transparent round beads.
(7) Spandex fiber: close to the flame: melting and shrinking; contacting the flame: melting and burning; leaving the flame: self-extinguishing; smell: peculiar smell; residue characteristics: white gelatinous.
(8) Chlorine fiber: near the flame: melting; contacting the flame: melting, burning, emitting black smoke; leaving the flame: self-extinguishing; smell: pungent smell; residue characteristics: dark brown lumps.
(9) Vinylon fiber: close to the flame: melting; contacting the flame: melting and burning; leaving the flame: continuing to burn and emitting black smoke; smell: unique fragrance; residue characteristics: irregular scorched brown lumps.
