1.5D 51mm Recycled Polyester Staple Fiber Containing Silicon Whitening

1 Stable quality

The raw material is the most important for quality control. Our raw material is PET flakes which are made of clean drinking bottles. We have dozens of staple suppliers with good quality PET flakes, and we keep developing new suppliers. In that case, we could keep our stock at a level of 2000MT, while the capacity is 100 MT per day. Therefore, we could keep the quality almost the same from lot to lot.

2 Nice resilience

The resilience of PSF is decided by raw materials’ viscose. The higher the IV, the resilience is better. We have our own quality inspection department to inspect the IV of each lot, and the IV value of all the material we are going to use must be over 0.72

3 Effective control on Fusion points

The fusion points of the fiber are caused by the PVC content in the raw material. The more PVC, the more fusion points. We will not use the material which has more than 200ppm PVC. We use an oven test to inspect the PVC content and also ask our suppliers use the same way to test it and then control the PVC content effectively.

4 Bright color

We only use the raw material with less than 1000ppm yellow flakes after the oven test, the color of the whole material will not turn yellow, and then the final produced fiber will show good and bright color.
