MineralsThe most widely known mineral in the textile industry is sodium silicate as a mineral stabilizer for hydrogen peroxide bleaching

L.N.’s challenge: look for other minerals with the good properties of sodium silicate and with success!!

Clay minerals have been selected on the specific characteristics and formulated in new auxiliaries for the textile industry

A selection of high quality minerals for excellent results

In hydrogen peroxide bleaching, both continuously and

discontinuously In continuous desizing of synthetics In post scouring reactive dyed and printed cellulosics

Amongst the big number of minerals, clays have very useful characteristics for textile applicationsSome clay-classifications:Kaolin (Aluminium: “China clay”)Semectite (Aluminium + Magnesium)Hormite (more Iron)Some exceptional properties of clay:

o Thickening agents in paintso Oil and dirt absorbero Absorber of inks in e.g. paper industryo Stabilizer for hydrogen peroxide bleacheso Softening agents in household products

CLAYSCLAYS

CLAYS

All these classes (and many sub-classes) have different characteristicsBecause of this different special industrial applications e.g. paper coatingIn the past clays were used by Indian and Egyptian women to clean and smoothen their faces and to shampoo their hair. Clay masks and still popular!The clay structure is based on sheets By separating these sheets e.g. by stirring, a very big surface is created This surface (till 800 M2 per gram) makes it possible to absorb all kind of components like dirt, oil, greases etc.This gives an unique detergency effect

CLAYSCLAYS

CLAYS

CLAYSCLAYS Clay mainly consists of SiO2 and Al2O3

Other ions may be present Mg, Ca, Fe, Li, Mn,….. Some clays can stabilize H2O2 bleaches

One of the new applications for clays is as a one-shot product for the discontinuous bleaching applications

It is based on this mineral technologyA clay based multifunctional auxiliary for the

discontinuous bleaching of cotton with hydrogen peroxide on jets, winches and overflows

Prescouring of PES/EL and PA/ELAlternative for the ecologically unfriendly

hypochlorite bleach

Excellent hydrogen peroxide stabilizerUnique wash performanceGood wetting out of the fabricExcellent lubrification propertiesLow foaming; no defoamer requiredEcologically very friendlyGives fabric a smooth handle


Why Should One Use Altranol GEO

Altranol GEO allows almost 35% reduction in the BOD & COD levels in the wash effluent

Altranol GEO further reduces the COD/BOD levels by eliminating/reducing the need for additional auxiliaries in treatment baths i.e. wetting agents, chelating agents, surfactants, lubricants & defoamers.

The effluent of treated textiles is easily & readily treated by flocculating, precipitating or filtering the natural clays & its adsorbed /precipitated contaminants, which are removed by any standard separation technique like filtering etc.

The resultant effluent is significantly more environmentally acceptable than current effluents containing organic components & inorganic contaminants.

Why Should One Use Altranol GEO

Altranol GEO, besides reducing pollution due to lower BOD & COD levels, also results in lower volatile organic chemicals(VOC’s)Altranol GEO is an outstanding lubricating agent providing a softer hand for treated textile goodsAltranol GEO is non-foaming & extremely effective in removing processing oils & excess auxiliaries & other impurities from the substrates. Treated substrates are cleaner which improves dyeability & dye penetration resulting in increased colour yields of 10~30%Altranol GEO is suitable for processing all textile materials i.e. all fibres, filament, yarns, fabric & all products made from them. They include textured & non textured filaments & yarns, woven, knitted or non-woven fabrics.
