It is our great pleasure to introduce to you with our new line of Denim Fabrics for Wine Dyed Jeans. We exhibited our eco-friendly wine-dyed denim jeans in June 2010, Denim by Premiere Vision. After our extensive research and development in natural dye, finally, we produced eco-friendly "wine-dyed denim fabrics," which are called “Winetex”. Our new “Winetex” are chemical free and harmless not only to human beings and also to the environment. ECOYAA only uses wine, eco-friendly dyeing materials and Korean traditional herbs for our dyeing process. According to the test results conducted by KOTITI (Korean Textile Development Institute), ECOYAA’s wine-dyed denim does not contain a single harmful ingredient to human body and the environment and the color fastness of the wine-dyed denim is measured to be Grade 4 or 5. For your information and convenience, the website and e-Book of ECOYAA Co., Ltd. are as stated hereunder: www.ecoyaa.com Sincerely,
