Another explanation is the long-term supply and demand perspective

In the long run, PET fiber chip, as intermediate products, do not face sustained expansionary pressures, so their price differential space is relatively controllable compared to other varieties.

From the running in recent years, it is basically impossible to see a complete set of fiber chip unit (new fiber chip unit are basically bright chip lines to support industrial yarn). There is only occasional increases in output caused by new unit commissioning, and after the spinning capacity is fully commissioned, this part of the increase will disappear again, meaning that the supply and demand of fiber chip can be adjusted for the long term.

In terms of demand, having gone through the period of capacity elimination competition with direct spun, chip spinning factories have basically stabilized. They mainly adopted a differentiation or customization route, having their own survival strategies. More often, their fluctuations follow the trend of demand, and sometimes their running may be more stable (relatively less expansionary impact).

The current fiber chip market is a relatively stable market, with a relatively high proportion of large factory contract sales, and spot sales proportions are not as large as for PSF. In the event of a temporary shortage of spot supplies, it can be relatively easily reflected. In addition, fiber chip market also has brand differentiation, which sometimes leads to structural differentiation.
