Identification of clothing fabric ingredients
Recently, due to labeling names and content of fabric ingredients are not standardized, allowing unscrupulous traders to take advantage of the opportunity to pass off inferior products as good products and to deceive consumers by passing off counterfeit products for authentic products. In order to help consumers accurately identify the actual main components of clothing fabrics, here is a simple and common sense identification that consumers can refer to when purchasing clothing.
A simple method to identify the composition of clothing fabrics is the combustion method. The method involves removing a strand of fabric containing warp and weft from the seam of the garment, lighting it withof the fire, observing the state of the burning flame, smelling the smell of the burning fabric and observing the combustion. The remaining residue is used to determine whether it matches the fabric composition listed on the clothing durability label to identify the authenticity of the fabric composition.
1. Cotton fiber and hemp fiber Cotton fiber and hemp fiber ignite as soon as the flame is close, burning quickly, with yellow flame and blue smoke. The difference between the two
burning odors and ashes after burning is that the burning of cotton emits a paper odor, and the burning of hemp emits a grass ash odor after burning, cotton
has very; little powdery, black or gray ash, while hemp produces a small amount of off-white powdered ash.
2. Wool fibers and silk wool smoke when exposed to fire, foam when combustion, burn slowly, smell like burning hair, and leave a lot of ash after burning
is a black, shiny spherical particle that breaks into pieces when pressed with fingers. When silk is exposed to fire, it shrinks into a ball and burns slowly, with a hissing sound and a smell of burning hair, after burning, it condenses into small dark brown spherical ashes, which can be broken into pieces when they are twisted. hand.
3. Nylon and polyester Nylon, whose scientific name is polyamide fiber, rolls up quickly and melts into a white gel when close to the flame.
3. Nylon and polyester Nylon, whose scientific name is polyamide fiber, rolls up quickly and melts into a white gel when near the flame.
p>
When combustion, there is no flame and it is difficult to continue burning without the flame. It smells of celery and cast ironn clear is difficult to grind after cooling. Polyester
The scientific name is polyester fiber. It ignites easily and melts when near the flame, it melts and emits black smoke, showing green flame and giving off aromatic smell. when burning, it becomes ashes. It is a dark brown piece that can be crushed with your fingers.
4. Acrylic fiber and polypropylene fiber. The scientific name for acrylic fiber is polyacrylonitrile fiber. It softens and shrinks near the fire, it emits black smoke and the flame is white. quickly after leaving the flame
and emits the pungent odor of roasting meat. After burning, the ashes turn into irregular black pieces that are easily broken by hand. The scientific name for polypropylene is polypropylene fiber. It melts and shrinks when near the flame. It burns slowly and emits black smoke when moved away from the fire.u. blue, giving off a petroleum odor. After burning
p>The ashes are hard, round, light yellow-brown particles, which are easily broken by hand.
5. Vinylon and chlorofluor. The scientific name for vinylon is formal polyvinyl fiber. It does not melt or shrink near the flame, and there is a point at the top when burning. /p>
Flame, when the fibers are melted into a gel, the flame will become larger, with thick black smoke and bitter smell. After burning, small black pearl-like particles will remain, which can be crushed with your fingers.
The scientific name of polyvinyl chloride fiber is polyvinyl chloride fiber. It is difficult to burn and goes out immediately after leaving the fire, with green and white smoke at the lower end, emitting an irritating and pungent odor.
It has a spicy and sour smell. After burning, the ashess become an irregular dark brown lump, difficult to crush with fingers.
6. Spandex and fluoronex spandex, whose scientific name is polyurethane fiber, melt and burn near the fire when burning, the flame is blue and keep melting and burning when leaving the fire.
Melting and burning, dispersing It emits a peculiar pungent odor, and the ashes turn into soft and fluffy black ashes after burning. The scientific name for fluoronon is polytetrafluoroethylene fiber. The ISO organization calls it fluorite fiber. It only melts near the flame, is difficult to ignite and does not burn. The peripheral flame is charred to a blue-green color and decomposes as it melts. , the melt
is a round, hard black pearl. Fluorinated fibers are commonly used in the textile industry to make high-performance sewing threads.
7. Viscose fiber and cupro-ammonium fiberViscose fiber is flammable, burns very quickly, has a ** flame, gives off a smell of burning paper and leaves less ash after burning
. p> Smooth fine powder twisted into a light gray or off-white ribbon shape. Copper-ammonium fiber, commonly known as tiger kapok, burns very quickly near a flame. The flame is yellow and has a sour smell, there is very little ash and only a small amount of gray-black. ash.
The threads of this piece of fabric that are burning and emitting black smoke are acrylic and polypropylene fabrics. The scientific name for acrylic fiber is polyacrylonitrile fiber. It softens and shrinks when near fire. It emits black smoke after catching fire and the flame is white after leaving the flame and gives off a pungent smell of roasting meat. After burning, the ashes turn into irregular black lumps and are easily broken by hand. THEscientific name of polypropylene is polypropylene fiber. It shrinks near the flame and is flammable when away from the fire and emits black smoke. The upper end of the flame is yellow and the lower end is blue, emitting an odor. of oil. After combustion, the ashes are hard, round, yellow-brown particles, which can be twisted by hand. So the threads of this piece of fabric that are burning and giving off black smoke are acrylic and polypropylene fabrics.
