Dyeing of Organic Cotton (CO)

Dyeing organic cotton (CO) is an important process step in the textile value chain. Mainly, the following three dye classes are used:

    • Reactive dyes
    • Direct dyes
    • Vat dyes

Organic cotton can be dyed with these different classes of dyestuffs either in exhaust or continuous processes, such as cold-pad-batch (CPB) or pad-steam. The choice of the dyeing procedure depends, among other things, on the existing machinery and the used dyes.

GOTS-Compliant Dyes

Information about GOTS-compliant dyes can be found on the official webseite of the Global Organic Textile Standard. They offer a search function where you can comfortably look for dyes from different dyestuff suppliers.

GOTS-Compliant Dyeing Auxiliaries

Textilchemie Dr. Petry hat verschiedene GOTS-konforme Textilhilfsmittel für das Färben von Organic Cotton im Angebot. Darüber hinaus bieten wir Ihnen ausgefeilte Verfahrensempfehlungen für die Färberei. Durch clevere Prozessoptimierung können der Verbrauch von Wasser, Energie und Chemikalien reduziert und damit die Umweltbelastung gesenkt werden. Schonendere Verfahren schützen nicht nur die Umwelt, sondern auch die Mitarbeiter in den Textilbetrieben.

The Global Organic Textile Standard (GOTS)

Der Global Organic Textile Standard (GOTS) gibt Richtlinien für die Produktion von Textilien vor, die mindestens zu 70 % aus Naturfasern aus ökologischem Anbau bestehen. Unser Angebot umfasst viele GOTS-zertifizierte Hilfsmittel für die verschiedenen Prozessstufen der Textilveredlung, Vorbehandlung, Färberei, Ausrüstung und Nassveredlung, dieser biologisch erzeugten natürlichen Fasern, wie Baumwolle, Leinen, Seide oder Wolle. Bei der Entwicklung und Herstellung dieser Textilhilfsmittel halten wir uns als verantwortungsbewusstes Chemieunternehmen, das großen Wert auf umweltbewusstes, nachhaltiges Handeln legt, an die Vorgaben des jeweils aktuellen Global Organic Textile Standards.

Multifunctional Dyeing Auxiliaries for Eco-Friendly Grey Dyeing

PERLAVIN NDA

PERLAVIN NDA ist ein multifunktionelles Färbereihilfsmittel für die umweltfreundliche Rohfärbung von Baumwolle. Das Produkt verfügt über gute netzende, waschende, dispergierende und sequestrierende Eigenschaften. Bei der Rohfärbung mit PERLAVIN NDA wird die Rohbaumwolle in einem Bad gewaschen und gefärbt. Auf einen separaten Bleichschritt kann verzichtet werden. This method helps tolower the COD and BOD load of the wastewater. The grey dyeing process is especially suitable for dyeing dark shades on knitted fabrics or yarns.

Wetting and Deaerating Agents

PERIWET ELR

PERIWER ELR isis a low-foaming rapid wetting and deaerating agent. The product is applicable for all kinds of fibers and can be used in acidic, neutral or alkaline media over the whole temperature range.

PERIWET SL

PERIWET SL is a versatile foam-reducing deaerator. It is applied as a rapid wetting and deaerating agent with defoaming effect for continuous as well as for discontinuous dyeing processes.

PERIWET ELB

PERIWET ELB is a low-foaming wetting agent. Due to its high alkali stability, it is particularly appropriate for the application in highly alkaline dyeing liquors, especially for cold-pad-batch dyeing (CPB).

Sequestering and Dispersing Agents

PERIQUEST BSD

PERIQUEST BSD is a very well biodegradable dispersing and sequestering agent. The product is used in textile dyeing because of its good complexing and dispersing properties. Non-fixed dyes can be washed out better together with PERIQUEST BSD.

PERIGEN LDR conc.

PERIGEN LDR conc. is an excellent sequestering and dispersing agent. It is applied for pasting and dissolving reactive and vat dyestuffs. It improves the solubility of reactive dyes.

PERIGEN ASW

PERIGEN ASW is a dye dispersant that is used in vat dyeing. It increases the stability of dyeing liquors and prevents precipitation and agglomeration of the vat dyes.

Levelling Agents

PERISTAL RDB

PERISTAL RDB is a special levelling agent for dyeing organic cotton with reactive dyes. The leveller improves the dispersion of the dyes in the liquor and ensures uniform, level and reproducible dyeing results. Especially with turquoise tones, the risk of stains and unlevel dyeing is reduced.

PERIGEN KPS

PERIGEN KPS is an excellent levelling agent for direct or vat dyeing. The product causes good penetration of the fabric with the dyeing liquor and thus promotes complete penetration and level dyeing of the material. The absorption of the dyes is slowed down by PERIGEN KPS and thus enables uniform, level dyeing.

Defoamers

PERIFOAM NSI NEW

PERIFOAM NSI NEW is a silicone-free defoamer. It is effective in acidic, neutral and alkaline media and works in both cold as well as hot liquors. Due to its high shear stability PERIFOAM NSI NEW is also suitable for the use on jet dyeing machines.

Soaping Agents

PERLAVIN SRD

PERLAVIN SRD is an effective soaping agent for textiles dyed or printed with reactive or vat dyes. The product removes hydrolyzed reactive dyes when soaping after dyeing or printing and prevents the agglomeration of dyestuff molecules. This improves the fastness level of the goods.

PERLAVIN SRS/N

PERLAVIN SRS/N is an excellent soaping agent for reactive dyeings and prints. In case of dark, color-intensive reactive dyeings, in most cases a single soaping treatment is sufficient to remove non-fixed dyes and thereby improve the level of fastness. PERLAVIN SRS/N shows good effectiveness even with high salt contents, so that rinsing baths before the actual soaping process can be saved. Additionally, it is suitable for soaping at 70 – 80 ° C.

Fixing Agents

PERFIXAN RDL/N

PERFIXAN RDL/N is a cationic fixing agent used to improve the wet fastness properties of reactive- and direct-dyed cellulose fibers.

Special Auxiliaries

PERISTAL OX

PERISTAL OX is a mild oxidizing agent for vat dyeing. The oxidation with PERISTAL OX can be carried out in a diluted dye bath or in a fresh bath without causing over-oxidation of the dyestuffs. As a protective agent it protects sensitive reactive and direct dyes from reductive influences which could cause changes in color.
