Textile fibres consist of natural, renewable raw materials or synthetic materials. natural fibres contain secondary substances which ar undesired on finished textiles. all fibre materials are treated with auxiliaries during spinning, weaving and knitting which have to be removed from the substrate for subsequent processing. the productrange of the pretreatment department includes all textile auxiliaries which generally are necessary to clean textiles. textile pretreatment is divided into the following process steps: desizing, alkaline scouring, bleaching, washing and optical brightening which are applied individually or in combination.

are blends of non-ionic and / or anionic surface active substances which dissolve the impurities of the substrate and keep it finely distributed in the washing liquors.

They are separated into products which mainly remove oily soilings or pigment soilings. Besides their main task of washing, detergents hae to meet special demands regarding foam and wetting behaviour which enable their usage on modern machines. Since detergents may reach waste water easy biodegradability is very important.

Sequestering Agents

All natural fibre materials have different contents of calcium and iron depending on their cultivation area. Since these metal ions disturb the subsequent processing they have to be removed by sequestering agents from the substrate.

Peroxide Stabilizers

90% of the textile fibres which are bleached are treated with the nonpolluting bleaching agent hydrogen peroxide which disintegrates into water and oxygen. In order to avoid loss of strength during the bleaching processes and to obtain a maximum of white the usage of products is necessary which allows a slow and controlled decomposition of the bleaching agent.

Optical Brighteners

are substances which transform UV light into visible light. these substances enable the production of high white textiles as they are demanded in the field of underwear, table linen and for curtains.
