Xinxiang Chemical Fiber's 4,000-ton spandex new capacity trial production is expected to reach volume production in November

Xinxiang Chemical Fiber’s 4,000-ton spandex new capacity trial production activity is in operation. It is expected that normal production will be realized in November.

Xiao Shubin said that the new production capacity is undergoing trial production and commissioning. Since trial production of new production lines requires adjustment and cooperation in all aspects, it is expected that the new production capacity will require a one-month cycle from trial production to normal production.

The new production capacity of Xinxiang Chemical Fiber Co., Ltd. will soon reach the second phase of the 12,000-ton continuous polymerization differentiated spandex fiber project. The release of this capacity will give Xinxiang Chemicals an incremental production capacity of more than 4,000 tons of spandex.
