Sustainable textile production

Conversation with: Regina Kallfelz, Team Lead Sustainability at DELTEX
DELTEX stands for sustainable textile production. What does that mean in concrete terms?

“This term defines our understanding of how we implement our own standards and those of our customer in practice, particularly within the production facilities. Sustainability is becoming more and more important in the textile sector, and consumers are becoming increasingly critical in the way they look at product quality in relation to the manufacturing process. For DELTEX, this is nothing new: we view cooperation with our production facilities and customers as an integrated activity, and our goods are produced exclusively in facilities that are inspected regularly by the DELTEX Sustainability-Team, by our customers and by independent institutes.”

Does this mean sustainability activities are managed by their own dedicated department at DELTEX?

“Of course – on the one hand, it’s a high-priority issue and on the other, it involves complex, multi-faceted tasks. It starts with the selection of production facilities. To manufacture good products, it is essential to choose the right production facility, which is why this decision is taken while the design is still being drawn up. DELTEX works with a stable base of producers and takes care to ensure transparency at every stage of the supply chain. That’s why we monitor not just the sewing workshops, but also the producers further back in the chain who manufacture and dye the materials (T2-T3). We also coordinate closely with the quality assurance department to make sure that our requirements are implemented at all times, both in terms of the product itself and in terms of the production facility.”

How do you make sure of these high standards on-site?

“One part of the DELTEX Sustainability Team trains and supports the production facilities in order to establish more on-site responsibility for the production processes, products, people and the environment. We believe that helping production facilities develop towards active sustainability management is one of our most important roles.”

And what if deficiencies should occur?

“DELTEX complies with the Production Facilities Development Approach. This means that rather than terminating the relevant business relationship immediately, we work to rectify any deficiencies and find solutions together. As far as we’re concerned, this is also part of sustainable textile production. Only in the event of serious violations of our sustainability principles, such as proof of bribery or enforced labour, would we terminate the collaboration directly.”


"The Green Button" is a government-run certification label for sustainably produced textiles. It sets binding requirements to protect people and the environment and thus gives consumers guidance when shopping. A total of 46 demanding social and environmental criteria must be met. What is special about the Green Button is that, in addition to the product, the company as a whole is always inspected. The German state sets the criteria and conditions for the Green Button. Independent inspection bodies monitor compliance with the criteria."

Quality Assurance

Cooperation is one of our top priorities: working in close coordination, employees from the technology, quality, product development and merchandising divisions make sure that every element of each individual order is of the highest quality possible – deltex quality.



  • comes thorough planning: we go through every aspect of production, working with the people in charge at the production site to determine the steps needed to optimise the implementation.
  • we develop and create individual offer samples and patterns, and make sure the fit is perfect.
  • we oversee the manufacture, dyeing and printing of the materials.


  • we carry out multiple onsite checks to make sure the products meet the quality requirements. To ensure this, our quality managers conduct inspections in accordance with the AQL level specified by the customer.
  • various checks also take place to ensure that the products are fit for purpose, durable and in full legal compliance. These are carried out both by independent institutes and by our Technical Team.


  • we’ll only make products available for delivery once we ourselves are convinced of their quality. Before releasing any item for a sample inspection by third parties, we check it ourselves, using both the customer’s error catalogue and our own.
  • we obtain feedback from our customer(s), and use it to make further improvements in our processes.

Marcel Herzbach, Managing Director, Procurement and Sustainability:

“A company that acts sustainably will remain successful even in a dynamic competitive environment and is facing up to its social responsibility.”

For us, being sustainable and responsible-minded means respecting the full range of legal requirements, using resources sparingly, promoting climate protection and living up to our obligations to our employees and society.

Sustainability and its implementation can also become a key competitive advantage, but only if reflected in the attitude and behaviour of every employee.

Our commitment to upholding human rights in our supply chain is firmly established in our DELTEX Human Rights Mission Statement and shapes and defines the work of our employees worldwide. To provide guidance for new employees and promote the values we practise and an understanding of how collaboration with our international partners works in this respect, the DELTEX Code of Conduct was integrated into our contracts some years ago. If there is a violation of the DELTEX Code of Conduct or any other complaint this can be communicated via our complaint form. Our aim is to ensure that our business processes are sustainably oriented and hence future-proof.

This includes determining the social and ecological effects of our business activity. We gather data from the entire supply chain, using systems like the amfori Business Social Compliance Initiative (BSCI) and the amfori Business Environmental Performance Initiative (BEPI). These feed into the DELTEX risk analysis from which our strategy for the future is derived. One key element in our risk analysis is the transparency of the supply chain.

Lisa Schröter, DELTEX Sustainability Manager

“For us, in operational terms, responsibility means keeping in close contact with the production facilities that work for us. We regularly check for ourselves how things are looking on-site in our production facilities. Several times a years, I and my colleagues in Bangladesh and China visit the factories of our strategic partners, inspect them and talk with the people there. Our work is guided by the DELTEX Sustainability Requirements (photograph), which define the company’s relationship with these factories.”

Certified raw materials

Our commitment to sustainability is also reflected in our products. Most of our clothing is made from sustainably produced raw materials, and we have GOTS, OCS, GRS and RCS certification.
