Generally speaking, polyester staple fibers on the market are divided into three categories: large chemical fiber, medium chemical fiber small chemical fiber.
Large chemical fiber: short fiber spun PET chips melt directly. Good color, large batch number, strong stable, few defects, good spinnability
Medium chemical fiber: it is spun with PET chips with pet recycled. The price quality are between the big the small (mainly some textile factories are used to improve the competitiveness with the big the small)
Small chemical fiber: spinning with pet. The price quality are in the same order, so they are suitable for export to some markets fields the quality requirements are too high (such as fillers, etc.)
Generally speaking, there are basically no defects in the short fiber spun by slicing. The fiber is uniform in thickness, smooth in surface, soft in hand (but to use the short fiber, there is a difference between adding silicon adding silicon in the coarse generation). If you pull it by hand, the general strength ratio of slicing is better, the batch number is large, there is no color difference, the physical index is uniform.
Generally, the batch number of short fiber produced by small chemical fiber regenerated raw material is small, the same algebraic hand feel is as good as that of large chemical fiber (except after treatment), there are many defects, occasionally uneven thickness, over length generally exists objectively, the physical index of conventional recycled material is slightly poor (strength, etc.)
