How To Identify The Quality Of Non Woven Products

Nonwoven Fabric is currently popular, and many people buy Non Woven Fabric without knowing how to identify them. In fact, according to the chemical composition of Non Woven Fabric Roll fibers, the combustion characteristics are also different, so that the main categories of aluminized non woven fibers are roughly distinguished. The comparison of combustion characteristics of several common nonwoven fibers is introduced as follows.

1. Polypropylene fiber: close to the flame: shrink; contact the flame: melt, burn; leave the flame: continue to burn; smell: paraffin; residue characteristics: gray - white hard transparent beads.
2. Cotton, hemp, viscose fiber, cupro fiber: close to the flame: non - shrinking and non - melting; contacting the flame: burning rapidly; leaving the flame: continuing to burn; smell: the smell of burning paper; residue characteristics: a small amount of gray - black or gray - white ashes.
3. Spandex fiber: close to the flame: melting; contacting the flame: melting, burning; leaving the flame: self-extinguishing; odor: peculiar smell; residue characteristics: white gelatinous.

4. Silk and wool fibers: close to the flame: curl and melt; contact the flame: curl, melt, burn; leave the flame: burn slowly and sometimes extinguish by itself; smell: the smell of burning hair; residue characteristics: loose and brittle black particles or coke shape.
5. Polyester fiber: close to the flame: melt; contact the flame: melt, smoke, burn slowly; leave the flame: continue to burn, sometimes extinguished by itself; smell: special aromatic sweetness; residue characteristics: hard black beads.
6. Vinylon fiber: close to the flame: melt; contact the flame: melt, burn; leave the flame: continue to burn, black smoke; smell: unique fragrance; residue characteristics: irregular charred brown lumps.

7. Nylon fiber: close to the flame: melting; contacting the flame: melting, smoking; leaving the flame: self - extinguishing; smell: amino smell; residue characteristics: hard light brown transparent beads.
8. Acrylic fiber: close to the flame: melt; contact the flame: melt, smoke; leave the flame: continue to burn, emit black smoke; smell: spicy; Residue characteristics: black irregular beads, brittle.
9. Vinyl fiber: close to the flame: melt; contact the flame: melt, burn, emit black smoke; leave the flame: self - extinguishing; odor: pungent odor; residue characteristics: dark brown lumps.
