AVCO-TRYL HPH
An acidic complexing-dispersing agent used for de-mineralization of textile fabrics contaminated with calcium, magnesium and iron residues and metal
containing lubricants. Use of AVCO-TRYL HPH enables to perform an acidic treatment, followed by alkaline peroxide bleaching process, using the same bath.This procedure saves water and machine time.
Properties & uses:
- Extracting precipitates of iron, calcium and magnesium non-soluble contaminations from textile fibres. After the de-mineralization process and adding alkali to the acidic bath, the product is complexing strongly the dissolved metal ions, and enables un-disturbed bleaching process with hydrogen peroxide. The results are improved whiteness, brilliancy and hydrophility of the treated fabrics
- Acting also as a de-crystallizing agent of water hardness in alkaline pH even when the quantity of total hardness is above the stoichiometric ratio. The product is dispersing calcium and iron precipitates, and keep them in a very fine dispersion, to avoid crystallization on the textile fabrics (threshold effect)
- Not lowering the strength of cellulosic fabrics and yarns
- The complexing capacity toward iron ions is increasing when raising the pH to strong alkaline solutions. The product is an excellent complexing agent for causticizing and bleaching processes of cellulosic fabrics
- Non-foaming at all
- Stable in acidic and in alkaline baths
- An excellent booster to improve detergency in preparation and bleaching-processes. Acting as a protective colloid and dispersant to avoid re-deposition of suspended dirt on the treated textiles
- Suitable for dyeing polyester fibres with disperse dyes in acidic pH
- Suitable for dyeing polyamide and spandex fibres with acid dyes
- Complexing metal soaps included in spandex lubricating oils
Ionicity:
- Anionic
