Recently, Yihua's bottle-slicing business unit has successfully developed permanent flame-retardant high-strength polyester staple fiber. The first batch of products have been sent to customers.
At present, the domestic flame-retardant fiber materials are generally formed by flame retardant treatment in the subsequent process. The flame-retardant polyester staple fiber researched and developed by Yihua is developed and produced with flame-retardant polyester chips as raw materials. It is a high-value-added product with no pollution, no corrosion, and even flame-retardant performance. After testing, its main performance index flame-retardant oxygen index is better than the national standard.
