Relevant Classification and Discrimination of Polyester Monofilament
Polyester (PET) monofilament: polyester filament
Main properties of polyester monofilament iron pipe
High strength, good elasticity, good wear resistance, good light resistance, poor hygroscopicity, poor dyeing. Polyester monofilaments must be dried for 4 hours to form a cooling pool with water temperatures ranging from 60 to 70 degrees Celsius. Polyester has higher hardness than nylon, but less toughness than nylon. It can be rolled in paper tube with polyethylene and polypropylene.
Polyester monofilament paper tube
type
There are many kinds of polyester monofilaments, such as flame retardant monofilament, triangular shaped monofilament, flat monofilament, high shrinkage monofilament, hollow monofilament, cationic monofilament, full extinction monofilament, anti-ultraviolet monofilament PET monofilament, etc.
purpose
Polyester monofilaments can be classified into industrial and folk uses according to their uses. In industry, it is mainly used for the skeleton of industrial conveyor belt, weaving filter mesh, Meiji mesh cloth, external casing of rubber thread, etc. In civil use, it is mainly used for supporting bags, ribbons, zippers, straw hats, curtains, wedding dresses, clothing and so on.
Sandwich mesh
Polyester monofilament can be divided into 20D, 30D, 40D, 50D, 60D according to specifications. Among the products of different specifications such as 2500D, 30D polyester monofilament is a new special fiber product with high added value. It has high environmental protection performance and is the basic raw material for shoes, bags and stage clothing. It has a very broad market prospect.
Discrimination mode
Combustion characteristics: close to flame softening, melting and coiling. It melts in the flame, burns slowly, has a yellow flame, the edge of the flame is blue, and the top of the flame emits black smoke. Leave the flame: Continue burning and sometimes stop burning and self-extinguish. Burning odor: slightly fragrant or sweet. Residual features: hard and black beads, not easily crushed with fingers!
