Hopeful New Uses for Spunbonded Polyester

China's annual production capacity of spunbonded polyester fabrics in 2004 was 41,900 tons which accounts for 6.8% of overall spunbonded nonwovens.

The spunbonded polyester output is 15,000 tons and its share in spunbonded nonwovens is 4.2%.

The share taken by spunbonded polyester in overall

As for the production of general spunbondeds like spunbonded polypropylene, good-quality production equipment is available everywhere around the world. So China or any other country can produce high quality easily.

In the case of spunbonded polyester, however, a high degree of know-how and technology are imperative at each production process because of a lack of the established manufacturing equipment. This is why China cannot produce spunbonded polyester at the rates in other countries.

China had 15 spunbonded polyester production lines as of the end of 2005. Its production capacity rose to 54,400 tons.

On the basis of technological developments, China is counting on the expansion of market in the following segments. For spunbonded lightweight polyester nonwovens, carpets, sheets inside car doors, sheets for the ceiling of automobiles, sheets for car trunks, electric cable goods, outdoor tents, drainage cover, packing materials,, filter materials and building materials.

For spunbonded heavyweight nonwovens, waterproofing materials, sheets for burying waste and filter materials.
