Pretreatment
We produce Pretreatment auxiliaries: specific chemical additives intended to remove the various natural or synthetic impurities that may prevent the dyeing bath from penetrating and spreading into the textile substrate.
Fibres must be bleached and made perfectly hydrophilic through proper preparation treatments that vary according to the polymer.
Our range of products consists of:
- Enzymes for desizing used to neutralize hydrogen peroxide residues after bleaching, modify the touch and surface of the treated article, and carry out biobleaching treatments on denim items.
- Detergents based on surfactants suitable for the preparation of fibres containing large amounts of natural fats or synthetic spin finishes, which may inhibit the hydrophilic nature of the textile if not adequately removed.
- Wetting agents considerably reduce the surface tension of a liquid and therefore allow for the quick and deep penetration of preparation and dyeing baths into textile substrates.
- Stabilizers, catalysts, and multi-function agents for bleaching regulate the development of the oxidizing agent used in the process for natural, artificial, and mixed fibres. They allow a higher degree of whiteness while limiting fibre degradation at the same time.
- Anti-foaming agents contrast and lessen the build-up of foam on the surface of baths.
- Crack mark inhibitors reduce fibre-to-fibre friction and fiber-machine friction to avoid or to reduce the formation of creases/barrenness that can often affect susceptible items
- sequestering agents prevent the build-up of incrustations/deposits in and on machinery and catalysis (creation of holes in the fibre) when working with potent oxidizing agents at a high temperature (bleaching) In desizing baths, they prevent the dissolving of any glue particularly sensitive to electrolytes and hardness and thus extend the bath's stability. In dyeing baths, they act as chelating agents for any extra-bath structure that might alter the successful outcome of a dyeing bath (color changes) or soil the machinery over time.
