As Japan faces its worst attack of hay-fever inducing cedar pollen ever, two domestic companies have come up with textile solutions which they claim will help suffers beat the hay fever blues.

Textile maker Miyuki Keori Co has developed a fabric it claims can prevent pollen from clinging to it with the help of nanotechnology; while Japanese apparel maker Golwin Ltd has put a trekking jacket on the market which it says prevents pollen sticking to it.

Unusually high volumes of pollen from cedar and cypress released this spring are expected to push down Japan's economic performance as so many people suffer from the allergy. The amount of pollen released into the air this year is about 30 times more than normal say experts.

Golwin's anti-hay fever sportswear employs nanotechnology polyester fibres dubbed 'Dorden' that control static electricity in the fibre and therefore prevent tiny pollen grains from being attracted to it. The company's anti-pollen North Face jackets are on sale for 15,000 yen apiece.

Nagoya-based Miyuki said it plans to start selling men's winter suits made of a different nanotechnology-based fabric later this summer that also promises to keep pollen from sticking to the suits. A new process will attach nanotech sized particles to the suits' woolen cloth that help stop pollen from getting stuck in the weave.
