Description

Automatic spandex filament dividing device

Technical Field

The utility model relates to a spandex spinning technical field especially relates to a spandex filament's automatic branch silk device.

Background

Spandex is a short for polyurethane fiber and is an elastic fiber. Spandex generally consists of a plurality of filaments, generally 10D/filament, 15D/filament, even 20D/filament, the smaller the theoretical number of filament, the better the evenness of yarn evenness, because the chance rate of overlapping shape is smaller, the production solution DMAC produced by dry spinning is harmful to the liver of human body, generally 0.5mg/kg is contained in 10D/filament, and if 15D/filament, 0.7mg/kg is contained, which exceeds the standard. The production method is various, and at present, dry spinning, melt spinning, wet spinning and chemical reaction methods exist.

The melt spinning is a method of heating a high polymer to a temperature higher than the melting point thereof to form a melt and spinning the melt.
