Durst, manufacturer of advanced digital printing and production technology, has received the coveted GOTS certification in version 5.0 for its new reactive ink system Alpha Ink R HD. The Global Organic Textile Standard (GOTS) is the most exacting seal of approval for the entire textile production chain and is also acknowledged by consumers to be a reliable quality standard. Introduced in March 2017, version 5.0 of the standard must be implemented within twelve months by textile manufacturers in the areas of bio-production, textile processing and textile chemistry; it has further tightened the environment criteria right along the whole supply chain. The new guidelines refer to clothing and other textile products consisting of at least 70 per cent certified organic fibres. All used chemicals including dyes and auxiliary substances must fulfill stipulated criteria in terms of environment and toxicology. Textiles produced according to the GOTS 5.0 guidelines give consumers the necessary transparency that these are sustainable products, which were also made under socially acceptable conditions.
