Not all che­mis­try is the same …

Wit­hout dyes, the­re can be no colou­red, high-per­for­mance fabrics – but the sel­ec­tion and use of the neces­sa­ry che­mi­cals are car­ri­ed out by us with spe­cial care and due con­side­ra­ti­on of eco­lo­gi­cal standards.

Our che­mi­cals management

Che­mi­cals manage­ment is one of the most important are­as of our envi­ron­men­tal manage­ment. Due to the pro­duc­tion loca­ti­on in Ger­ma­ny, Ger­man and Euro­pean legis­la­ti­on alre­a­dy sets a high stan­dard for envi­ron­men­tal pro­tec­tion and occu­pa­tio­nal safe­ty. All dyes and auxi­lia­ries used are kept in a che­mi­cal regis­ter, and employees in the rele­vant are­as are trai­ned accor­din­gly. When sel­ec­ting pro­ducts, the focus is not only on sui­ta­bi­li­ty and qua­li­ty but also on other fac­tors, e.g. emis­si­on data, AOX con­tent and also pro­duct cer­ti­fi­ca­ti­ons. The con­sump­ti­on of dyes and auxi­lia­ries in our pro­duc­tion depends on various fac­tors: Desi­red colour and colour inten­si­ty, com­po­si­ti­on and gram­mage of the fabric, as well as finis­hing and qua­li­ty requirements.

Our stan­dards

For more than 25 years, our pro­ducts have been cer­ti­fied accor­ding to the OEKO-TEX® STANDARD 100. Ket­tel­hack was one of the first com­pa­nies to be cer­ti­fied accor­ding to this stan­dard in 1992. Sin­ce then, we have had our ran­ge of fabrics tes­ted every year by a labo­ra­to­ry for com­pli­ance with the spe­ci­fied limit values.

In addi­ti­on, we are a mem­ber of the Part­ner­ship for Sus­tainable Tex­ti­les and have thus com­mit­ted our­sel­ves to com­ply­ing with the ZDHC stan­dard on the use of che­mi­cals. This means that all dyes and auxi­lia­ries used meet the requi­re­ments of ZDHC-MRSL 2.0.

The OEKO-TEX®STeP MRSL also covers all che­mi­cals that are ban­ned for inten­tio­nal use under the cur­rent ZDHC MRSL. In addi­ti­on, the STeP che­mi­cals list also includes all sub­s­tances and para­me­ters requi­red under the ZDHC Efflu­ent Directive.

ZDHC stands for Zero Dischar­ge of Hazar­dous Che­mi­cals and is an asso­cia­ti­on of tex­ti­le and foot­wear manu­fac­tu­r­ers. The ZDHC stan­dard is a so-cal­led Manu­fac­tu­ring Rest­ric­ted Sub­s­tances List (MRSL for short). The organisation’s goal is to redu­ce pol­lut­ants in pro­duc­tion towards zero. The cur­rent ZDHC MRSL 2.0 is accom­pa­nied by various hand­outs on the con­cre­te imple­men­ta­ti­on of the requirements.

Our che­mi­cal management

Pre­cis­i­on work is required!

Cer­ti­fied dyes and auxi­lia­ries, lots of expe­ri­ence – and a trai­ned eye. The dye­ing pro­cess used depends on the raw mate­ri­al. While disper­si­on dyes reach the insi­de of the fib­re through a ther­mal pro­cess, vat dyes and reac­ti­ve dyes build a che­mi­cal com­pound with the fibres.

“You may hear talk about ‘good’ che­mi­cals and ‘bad’ che­mi­cals, but the truth is that che­mi­cals are neither good or bad. What mat­ters is the con­text, how and whe­re they occur and how they’­re used.”
