Walls Of Earthtex™


D
esigntex
— a New York City-based design and
product development company specializing in textiles, wall coverings, architectural panels, shades,
screens and other commercial and residential interior products — has developed Earthtex™, its first
polyvinyl chloride (PVC)-free woven wall covering and the next generation of its Hardwear™
collection of upholstery and wall covering fabrics. For Designtex and its parent company, Grand
Rapids, Mich.-based office environments manufacturer Steelcase Inc., Earthtex represents one step
toward their goal to remove PVC from all products by 2012 — part of an overall, ongoing strategy to
make their operations and products as environmentally sustainable as possible.

According to Carol Derby, director of research and development, Designtex, the traditional
Hardwear wall coverings are made using a PVC-coated polyester fill and a polyester warp. By
comparison, Earthtex wall coverings are made using EarthTex™ solution-dyed 100-percent
thermoplastic olefin (TPO) fill yarn, which has a polypropylene (PP) core and is coated with a
blend of PP and polyethylene olefins, and an olefin warp. Because there is no contamination of one
olefin by the other, Earthtex product manufacturing trimmings and waste can be recycled into new
product. The end-product also has been designed to be recyclable once a reclamation program for
such products is in place.

and an olefin warp, are designed to be recyclable once a reclamation program is in place to receive
them.


In addition to being PVC-free, the
company notes, Earthtex also contains no heavy metals or plasticizers, is inert and therefore
nontoxic in a landfill, and requires much lower temperatures for processing than PVC. With all
these environmental advantages, the product offers durability comparable to that of the traditional
Hardwear wall coverings. In addition, because Earthtex is solution-dyed — the other Hardwear
products are not — it offers improved cleanability, Derby said.

The standard Earthtex fabric has an acrylic backing that typically is knife-coated in a
liquid state onto the fabric, which then is dried in an industrial dryer or oven. As an
alternative, more environmentally sustainable solution, Derby said the company will apply a
polylactide (PLA) backing when it is specified. She noted PLA is water-soluble, adding that the
company plans to make PLA its standard backing as the cost comes down.

Designtex is marketing its Earthtex line especially for health care applications, but the
products also are suitable for hospitality and corporate environments.

The first two Earthtex wall covering styles are being made available this fall, and other
styles are planned using EarthTex in combination with other olefins.

“Interesting textures can be achieved by combining EarthTex with other olefin yarns,” Derby
said, noting there also are opportunities going forward to use it in upholstery. “It’s a soft,
supple yarn. A lot of work went into making it that way.”
