How to verify the quality of polyester short fibers?

Polyester short fiber quality standards, grades, industrial handover, etc., can be used in instrument test, while polyester short fibers color, color, openness, fiber bonding, ultra-long fiber distribution, etc., etc. The sensory test is required. Only the instrument test is combined with the sensory test to comprehensively evaluate the quality of polyester short fibers.

Polyester short fiber color, gloss directly affects the color and layout color difference and the color difference after dyeing, so it must be paid attention to observing the color difference between the batch and the batch and the different origins, through the visual alternating process. The degree of difference is to determine how much alternatives are given each time to avoid wires and layout.

In the clearing process, the extent and the size of the polyester short fibers directly affect the formation and viscosity of the polyester roll, and the tightness of the polyester roll, loosely fall off, and the like. To this end, the inspection of these two projects is also very necessary. When testing, you can see the fluffy of the fibers, and then grasp the fibers.

After gripping the polyester sample, feel the elastic size, the flexibility, the flexible flexible, and the smoothness of the swell is good, and it will be clear.

When verifying the bonding force of the fiber, the polyester short fibers can be pulled open, and during the process of kicking, while the feeling of force is small, listen to the friction size, large force, rub the sound, and the holding force Big, and the opposite is weak.

The above is the sensory test for polyester short fibers.
