Pre Treatment Auxiliaries

Pre Treatment Auxiliaries by Neochem

Pre-treatment is where textile processing either sets itself up for success or plants the seeds of every problem downstream.

Before dyeing begins, fabric needs to be genuinely clean: free of sizing agents, natural waxes, oils, and residual chemistry carried from the loom or knitting machine. 

When pre-treatment is done right, the substrate is uniform, absorbent, and chemically ready. When it isn’t, no correction at the dyeing or finishing stage fully recovers what was lost. 

Shade variation, poor colour uptake, and inconsistent batch results almost always trace back to a pre-treatment stage that wasn’t controlled well enough

Frequently Asked Questions

What is the function of a peroxide killer in pre-treatment?

After hydrogen peroxide bleaching, residual peroxide in the fabric must be fully eliminated before dyeing begins. Even trace carry-over will oxidise reactive dyes, causing shade variation and fixation failure. A peroxide killer neutralises this completely and rapidly, so the dye bath starts with a chemically clean substrate every time.

Yes. The full pre-treatment range, including KLARITOL® Pro 8700, is formulated APEO-NPEO free, meeting the restricted substance requirements of GOTS, ZDHC, and international brand RSL programmes.

Yes. Mills processing specialised constructions, blended substrates, high-stretch knits, denim, or technical textiles, can work with our application team to adapt formulations to their specific process parameters and water conditions.

Yes. The KLARIZYM® enzyme range includes variants for pad-steam and pad-batch continuous processing. KLARITOL® Pro 8700 and the MERCOL® range are also formulated for continuous application, with dosage guidance available from our technical team

Role of Pre-Treatment Auxiliaries in Textile Manufacturing

Pre-treatment auxiliaries work across four interconnected stages: desizing, scouring, bleaching, and neutralisation, and each one sets the conditions for the next.

  • Desizing removes sizing agents completely, so the fibre surface is open and receptive. 
  • Scouring strips natural waxes, oils, and non-fibrous impurities that would otherwise cause uneven dye penetration. 
  • Bleaching achieves the whiteness target without damaging fibre integrity, a result that depends entirely on a stabilised, controlled peroxide reaction. 
  • Neutralisation brings the substrate to the correct pH before it enters the dye bath, protecting the chemistry that follows.

For mills running high volumes across mixed fabric types, control at every one of these stages isn’t a technical detail. It’s what separates predictable output from reactive problem-solvin

Combined wetting and scouring agents that simultaneously drive rapid liquor penetration into the fabric while emulsifying and removing fats, waxes, and oils from the fibre surface. Variants include: 

  1. KLARITOL® Pro 8700

Stain removing agents

Targeted formulations for breaking down and lifting process stains, grease marks, oil contamination, and preparation residues from fabric prior to bleaching or dyeing. Variaants include: 

  1. KLARITOL® SR series

Bleaching aids

Surfactant-based auxiliaries that improve the efficiency of the hydrogen peroxide bleaching bath by ensuring even liquor distribution, reducing surface tension, and improving wettability during the bleach cycle. Variants include: 

  1. KLARITOL® BLA series

QUNOX®

In textile processing water, dissolved heavy metals, iron, manganese, and copper, catalyse uncontrolled decomposition of hydrogen peroxide, leading to fibre damage, uneven whiteness, and poor bath stability. 

Sequestering cum chelating agents

Powerful chelating agents that bind and deactivate dissolved metal ions, particularly iron and manganese, present in process water and in the fabric itself from previous processing stages. Variants include: 

  1. QUNOX® SEQ series

Peroxide stabilisers

Controls the rate and uniformity of the hydrogen peroxide bleaching reaction at elevated temperatures, typically 90°C to 100°C, ensuring that peroxide is consumed evenly and gradually rather than decomposing rapidly at hot spots. Variants include:

LUBIMAK®

Protect fabric from mechanical damage and deformation during the high-tension, high-temperature conditions of continuous and exhaust pre-treatment processes. 

Anti-creasing agents

  2. LUBIMAK® chelation series

NEUTAX® 

NEUTAX® prepares the substrate for dyeing by neutralising residual peroxide and alkali, helping prevent shade variation and ensuring consistent dye fixation.
