What Are the Raw Materials of Polyester Staple Fiber?

Generally speaking, there are three types of polyester staple fibers on the market: large chemical fiber, medium chemical fiber, and small chemical fiber.

Large Chemical Fiber: short fibers that are spun or melt-spun with PET. Good color, large batch number, strong and stable, less defects, good spinnability.

Medium Chemical Fiber: Use external PET chips or PET back spinning. Price quality is between large and small.

Small Chemical Fiber: spinning with PET. The price and quality are uneven, suitable for export to some markets and fields where the quality requirements are not too high (such as fillers, etc.)
