Yarn maker Unifi Inc is increasing its polyester texturing capacity in the US and Central America to support growing demand for synthetic yarn in the NAFTA and CAFTA regions.

The expansion – which increases capacity by up to 10% – involves adding texturing machines at its facilities in Yadkinville and Madison in North Carolina, as well as El Salvador, with installation of the new machinery due to be complete by June 2015.

The move will also support growth in the company’s premier value-added product lines, thanks to new and expanding programmes with customers such as The North Face.

Unifi says the expansion reflects its commitment to the Americas and to servicing the growing number of customers who choose to source their products in the western hemisphere. The company claims regional synthetic apparel production has grown at an average of 5-6% annually over the last five years.

"We are very encouraged by the continued growth of synthetics in the US and Central America, and the opportunities it presents for the textile industry," says Roger Berrier, president and COO.

"We work closely with our customers to understand their production needs, and we are committed to investing in this region to provide the increasing amounts of synthetic yarn and other innovative products they require."

Unifi's yarns include its flagship Repreve eco-friendly products made from recycled materials, and are used by major apparel and hosiery brands.
