Nike推出第二款CO2無水染成衣

Nike推出第二款使用由荷蘭DyeCoo科技公司率先開發的CO2無水染色技術所染的成衣產品。Nike的ColorDry網球polo衫使用無水染色方法，該方法還可避免在布料染色過程中添加化學品助劑。此外，該polo衫使用96％的再生聚酯製成，也是Nike支持永續發展的證明，一件polo衫等同約使用11個寶特瓶。

告知媒體：「Nike身為一家創新的公司，不僅在產品設計方面講求創新，同時對於如何製造產品也講求創新。新的ColorDry 網球polo衫就是Nike追求永續材料及創新製造技術的實例，不僅降低對環境的影響，同時也將該網球衫的卓越性能傳遞給運動員。目前，無水染色技術仍處於發展初期，但依然是Nike承諾減少對有限資源，例如水的依賴的一部分」。

二氧化碳染色係將二氧化碳加熱至31℃以上，並加壓至74巴（大氣壓力）以上 ，此時就達到超臨界狀態。超臨界流體是在溫度和壓力高於其臨界點的物質，高於此點，就不產生明顯的液體及氣體現象，因此，CO 2具有液體及氣體二者的特質。

DyeCoo的染色機器採用不鏽鋼染缸，其中超臨界流體CO2，不需用水即可用於紡織材料的染色。超臨界流體CO2可以提高無水染人造纖維的效率，此過程能夠緩和分散染料在纖維內擴散。在相同的染缸，也可進行布料乾燥和除去過量的染料。過程中，多餘的回收染料不致浪費，可以回收及循環再利用，DyCoo聲稱，CO2無水染僅需使用傳統染色製程一半的的能量。

多項預估資料顯示，以傳統方法染一件T恤大約需要使用30公升的水。

Nike unveils second ColorDry dyed garment

US sporting goods giant Nike has unveiled a new tennis polo that becomes its second ColorDry garment made using fabric which is dyed using CO2 instead of water, in a process that also saves energy and eliminates the need for added chemicals.

Nike invested in ColorDry, developed by Dutch start-up DyeCoo Textile Systems, last year when it launched its first product dyed using recycled CO2, saving up to 30 litres of clean water per dyed T-shirt.

DyeCoo described the technology as “game-changing”. As reported last year, the ColorDry fabric is produced in a new water-free dyehouse in Taiwan that has been set up with manufacturer Far Eastern New Century Corp (FENC).

The new tennis polo is also made with 96% recycled polyester, from recycled plastic bottles melted down to produce the high-performance yarn - each polo is made with the equivalent of 11 plastic bottles.

It also combines the sustainable innovation of ColorDry with one of Nike's key performance innovations, Dri-Fit, which helps draw sweat away from the body through the fabric. Nike says the polo’s design delivers unrestricted range of motion from the baseline to the net.

Nike was the first company to back the Detox challenge set out by environmental pressure group Greenpeace in 2011 to eliminate the discharge of hazardous chemicals from their supply chains by 2020. Since then, more than 20 brands and retailers have joined the pledge, including Adidas, H&M and Primark. 

The tennis ColorDry polo is available in black, blue, orange and lime green in select Nike retail stores.
