Sulfur dyes has a shade of pure high color, low prices, even dyeing. But because of oxidation commonly used dichromate - acetic acid, to cause wilt fabric shade darker, rougher feel, the less hydrophilic. Its Achilles heel is toxic First, the wastewater contains a certain amount of Cr6 + toxic compounds, and its crops, microbes and other organisms have a great harm. Trace complex state of chromium ion in the deposition of the surface of the cloth, making the product less than the required standard. Chromium oxidants to solve these problems. Was used to detect contrast with non-toxic environmental protection, including heavy metals, this product meets the EU standards for export products. 
 Feature 
 Improve the smoothness of cloth, to keep the fabric has good hydrophilicity and feel; 
 Chromium oxidants cloth no "sour"; 
 The oxidation process is easy to control and will not cause excessive oxidation; 
 Maintain a considerable amount of color fastness and dichromate oxidation.
