In the case of old fabrics that are not particularly experienced, identification of fabrics may be difficult. Combustion test
It is usually the most accurate way to identify the fabric when done correctly. Please be careful when you do
Combustion test Only a few cloths (2 inch square or 4 inch 3 to 4 individual strands) are burned. Burn
A ventilated place without drafts and fans. Please use a smelly neutral room and needle pair
Pliers and scissors to hold the cloth. Finally, burning in incombustible places such as metal sinks
Glass bowl, dish, or baking tray. It helps to keep a large glass of water and a good spray bottle
To be on the safe side! Do you want to know where to cut the dough? Look for extra material with internal seams
Keep these additional materials away from the hem line and waist seams as it is ideal for future renovations.
Many wool and cotton are also chemically treated, which also affects the test. As
The general rule lists its nearest structure, but it also shows that the burn test is not conclusive.
You can not be 100% sure. The most common is that rayon and acetate are mixed in the fabric.
1940 's, 1950' s, and the early 1960 's. Since the late 1960's, its polyester fiber has emerged in its history. Pure polyester
Polyester ignited the earliest. When it ignites, the flame is approximately 1 inch from the fabric. I burned in a flash. Most fabric burns to ash in only a few seconds. Denim will ignite for the longest time. If you test which cloth is the most secure near the flame, it is denim. Polyester is very dangerous to wear by the fire. Nylon: Nylon is used for various purposes. Clothes are one of them. Nylon was invented by a group of researchers led by organic chemist Wallace H in 1938. The production of ordinary nylon (nylon 6, 6) begins with basic hydrocarbons under pressure and heat, synthetic chemicals adipic acid and hexamethylenediamine. (Other nylon production may require slightly different acids and amines.) They are mixed to form a substance called nylon salt. This concentrated salt solution is heated with a huge kettle called an autoclave
It ignites and burns immediately, and it keeps burning even after the flame has been removed - be careful when exercising. The fiber shrinks from the flame, melts, drips (danger), so hard plastic beads remain. Burning these cloths produces black smoke and harmful fumes. Nylon smells like plastic when it is burned, but it also produces a smell like celery; acrylic burns with a strong chemical smell of strong stimulation. Polyester has a somewhat sweet taste due to its chemical smell
It is made of petroleum. Because of the surface of those fabrics, they burn quickly and shrink into a flame. Beads are hard, gray and not brittle. When the flame burns it slowly burns and melts. Though they are self-extinguishing, there is a danger of dripping. They smell like celery, they leave no ash, but soot is very dangerous. It is a polymer made from coal, air, water, petroleum products. It burns quickly and shrinks from the flame, and it can burn. Hard, dark and round beads remain. After a flame it burns slowly and does not always extinguish. There is a slightly sweet chemical smell. Ash will not remain, but black smoke and smoke are dangerous
