The difference between polyester staple fiber and polyester long fiber, polyester fiber is the most commonly used chemical synthetic fiber today. Mainly polyester staple fiber and polyester filament.
At first glance, polyester staple fiber is a short fiber with a length of several centimeters to ten centimeters, while filament is a fiber with a length of more than one kilometer. Generally, it is stored in a roll and burned into a dough.
The difference in quality and raw material of polyester staple fiber and filament Large chemical fiber: short fiber spun from chip or melt directly. Features: Good color, large batch number, strong and stable, few defects, good spinnability.
Small chemical fiber: spun with PET back material. Features: The price and quality are uneven, suitable for national conditions, and exported to some shopping malls and categories (such as filling materials) that have low quality requirements.
The difference between polyester staple fiber and filament equipment Usually large-scale chemical fiber equipment will introduce a batch of advanced foreign or domestic top-level production equipment, which is generally oriented to the high-end market. The product quality will have high indicators, the defective rate is extremely low, and the spinnability is high. Conversely, some small enterprises or some small-scale manufacturers will purchase obsolete equipment, and the raw materials will also use lower-cost secondary recycled materials.
The color difference between polyester staple fiber and filament Drift the two to see the color. Dahua will perform worse in terms of colorful colors, but better coloring.
