Half century for Dacron

DacronDacron, Advansa’s emblematic polyester brand, celebrates 50 years as the first fibrefill product for the European home textiles market in 2010.

Inspired by the research of Wallace Carother, who invented neoprene and nylon for DuPont, two British chemists, John Rex Winfield and James Tennant Dickinson, turned their attention to polyesters made from ethylene glycol and trephthalic acid. After several years of research and work, they invented and patented PET.

DuPont launched production of Dacron as the first washable synthetic textile fibre for clothing applications in the USA in 1950, then followed through with Europe’s first fibrefill product for home textiles in 1960.

Polyester went on to revolutionize modern society and invigorate the chemicals industry and also turned a new page in the history of sleep – polyester-fibrefill duvets have changed the sleeping habits of generations to come by offering radically improved comfort properties – insulation, anti-bacteria, moisture-evacuation, heat-regulation, etc. – along with user friendliness and low maintenance. Somewhere between 60% and 80% of duvets sold in Europe today are made with polyester fibres.

Working in partnership with manufacturers, first of wadding then of pillows and duvets, DuPont started off European sales of Dacron with the first pillow filled with solid fibre. Second-generation Dacron fibres featured a silicone-based finish, for enhanced softness to the touch. This first, in a long list of groundbreaking innovations was introduced first under the Adoration brand, then under the name of Elégance for duvets.

Technical innovations went hand in hand with an advanced process, including a traceability system and licence arrangements with finished product manufacturers. as well as TV advertising and targeted point-of-sale communications.

The first hollow fibre, introduced in 1971, was the next innovation.
By studying the fur of the polar bear and the caribou living in extreme weather conditions, DuPont engineers discovered that the animals resisted the cold thanks to thousands of air pockets. Consequently, they set about applying the same principle to their polyester fibre products. The Dacron production facility at Uentrop in Germany was opened in 1968 and is still running today.

Among new Dacron products introduced for the bedding market at this year’s Heimtextil was  Suprelle Memory – new pillow made of a new, ‘intelligent’ fibre material that is pressure-relieving and breathable, along with Hollofil Spring, which provides high loft and form retention for long-wearing mattress pads.

Suprelle Memory is an ergonomic, but not pre-formed pillow with pressure-relieving qualities similar to viscose foam, based on a concept of filling made of 100% polyester fibres in combination with a special covering.

The memory effect of the material ensures that the pillow adapts temporarily to the respective head and neck structure and supports the corresponding parts of the body without restricting the sleeper’s freedom of movement. The high humidity management and breathability of pillow core and covering avoid sweating and provide for a good microclimate.

Hollofil Spring provides extremely high loft and outstanding shape retention without compromising low filling weight. This is ensured by a newly-developed technique for the multiple crimping of fibres Advansa calls Advanced Spiral Crimp. It is also available as an eco version which is in the final certification process for the European Union Eco-label and with an Allerban treatment that is friendly to allergy sufferers and restrains the growth of house dust mites, fungi and bacteria.  Source nonwovenslive.com
