POLYESTER STAPLE FIBER

The polyester staple fiber production is one of the most powerful industries in Jiangsu Sanfangxiang Group Co., Ltd. The corporation has sixteen sets of imported fiber product lines with the world's largest single line production capacity and consummate testing apparatuses. There are a number of excellent technicians and with one product research and development center, which ensure varieties and stable quality of products. The achievement of the 950,000-ton production capacity for polyester stapler fiber (including 900,000 tons for polymer directly spinning and 50,000 tons for chip spinning) has enabled the corporation to become the largest supplier of polyester staple fiber in domestic market. The business tenet of "Doing business with honesty and satisfying the customer" enables the products not only brisk sales in domestic market but also abroad. Besides the normal staple fiber of 1.56 X 38mm, the upper-fine denier fiber, wool type fiber, cation fiber, special fiber for lustrous sewing thread, medium and long fiber, colored fiber, triangular profile fiber and top filament are produced. The special fiber also can be developed and produced to meet the special demands of customers.
