Characteristics of the fiber or fabric |
Trying to smoke |
Synthetic fibers (all these fibers are not very hygroscopic) |
Polyacrylonitrile fibers, e.g.. Wolpryla, Anilana |
Durable fibers, elastic, strongly twisted (they resemble merino wool), with high capacity of the so-called. "Walking away" after crushing; grainy to the touch, very resistant to mint, with little inclination, to wrinkle. Application: in conjunction with the dederon, wool and viscose fibers for the production of fabrics and knitted garments and knitted garments |
It melts into a brown mass, then it burns up, releasing soot, no special smell |
Polyamide fibers, e.g.. Elastil, Modylon, Polan |
Fibers with a high gloss, thin, very hardy, smooth and strong, flabby to the touch, because amorphous, resistant to tearing and friction. Application: women's stockings, men's socks, blouses, men's shirts, personal underwear, dress materials |
No ignition. The fibers melt slowly in the flame, creating clay-cotton, glassy, dark brown mass. On combustion, an odor resembling denatured alcohol is released. Small bubbles are characteristic, which are formed on melting and break again |
Polyester fibers, e.g.. Bistor, Elana |
They feel like silk or wool to the touch, are characterized by the durability of the form, and therefore little crease, they are very flexible and strong |
No ignition, the fibers melt without any special smell |
Polyvinyl chloride fibers |
Matt fibers, resembling worsted wool. Resistant to acids. Application: for work clothes, knitted and wool-like products and anti-rheumatic underwear |
No ignition, the fibers are roasted in a flame cone, they turn black, giving off an unpleasant burning smell |
Copolymers |
Amorphous fibers, smooth and very flexible, soft and springy to the touch, very resistant to friction. Application: stockings, linings, personal underwear, technical fabrics |
No ignition, the fibers melt, shrink when heated, forming small balls or contracting when softening. Smell reminiscent of burning paper |
