SEOUL ? [13.12.07] Hyosung says it has developed a new generation of recycled nylon 6 filament yarns for use in intimate apparel and lingerie that are made from post-consumer waste products such as nets and carpets.
The Korean-based fibre producer, which is best known for its ?Creora?-branded elastane says the new ?Mipan Regen? fibre will feature in a brand new intimate apparel fabric collection at next month?s Interfiliere show, which runs alongside the Salon de La Lingerie in Paris.

?As one of the world?s largest producers of nylon 6 fibre, Hyosung?s Nylon Performance Unit has had a long history of environmental stewardship by capturing and recycling waste material during the manufacturing process,? said the company, but added that it is now ?recycling post-consumer waste from a broad array of nylon commercial products including nylon fishing nets, nylon fabrics and BCF carpets.?

Hyosung says that its new ?Mipan Regen? also delivers the same first quality and performance as its other virgin nylon yarns.

Despite several research projects in the 1990?s to recycle nylon for use in apparel, the nearest the textile industry came to a successful breakthrough was in the carpet industry. This was largely because recycling nylon is a much more challenging repolymerisation process than it is for polyester.

However, earlier this year, Toray Industries adapted its ?Recyclon? system for the production of recycled polyester yarns to cater for an anticipated growing demand for recycled nylon apparel fabrics and hopes to scale up this process in the near future.

Compared to clothing produced with fabric made from oil-derived virgin nylon 6 fibre, it isclaimed that making clothes with recycled nylon 6 consumes only one-sixth of the energy and emits one-fifth of the carbon dioxide compared to using virgin nylon.

The next challenge for the nylon industry is now to develop an effective process for recycling and re-using the more heat durable nylon 6,6 (instead of nylon 6) which is widely used in sportswear, activewear and performance apparel. Recycled nylon 6, 6 has been used in the carpet and flooring sector by innovative companies such as InterFace for its InterFlor products, but the separation of the two nylon 6,6 monomers still remains difficult to achieve in a cost-effective depolymerisation process.

Most often, nylon 6,6 is melted into a liquid plastic form and ?downcycled? rather than truly renewed and re-made into carpets or apparel fabrics.
