Sherisoft SSSherisoft SS is a very good antistatic-softener for finishing of textile and knitwear, made of natural fibres and synthetic blends. Especially suitable for finishing of textile and knitwear from wool and natural silk.
Mixture of alkylimidazolines, non-ionic surfactants and silicones.
|Solubility||Dissolves easily in water at temperature of 30-40 оС. Opalescence solution with slight acid reaction|
|Compatibility||With cationic and nonionic surfactants|
|- to рН||Stable in the range of рН 4 - 7|
|- to hard water (according to DIN 53905)||Clear conditional stability|
SHELF LIFE AND STORAGE CONDITIONS:
At normal weather conditions – 1 year. Avoid freezing.
Sherisoft SS has significant affinity to fibres. It is exhausted relatively quickly, as a result of which the concentrations in the used baths constantly decrease. With periodic processes and multiple use of bath, the bath concentration should be corrected after each charge. With continuous processes, fresh solution should be added in quantity, consistent with the type of material and equipment.
In very diluted baths the textile is processed for 10 min at temperature of 25-40 oС; in dyeing machines - 10-20 min at temperature of 25-40 oС; with foulard – the procedure is standard.
When bleaching with optical brighteners, usually anionic, the bleaching and softening with SherysoftSS are carried out consecutively (NEVER simultaneously!)
The dosage depends on the type of the material, bath modulus, equipment and desired effect.
The table below contains some examples for the use of SHERISOFT SS:
(fibres, fabrics, knitwear, yarns)
М 1:1 g/l
М 1:10, М 1:20
|Wool||20 - 25||1,5 - 2,0% of material’s weight||-|
|Wool/polyester||20 - 35||1,5 - 2,5% of material’s weight||-|
|Cotton||20 - 40||1,5 - 2,5 g/l||1,5 - 2,0 g/l|
|Cotton/polyester||20 - 30||-||2,0 - 2,5 g/l|
|Natural silk||20 - 40||-||-|
For carding and grinding of cotton textile and knitwear from polyamide fibres should be used the maximum concentrations in the table.
These instructions are informative. We recommend being adapted to the specific conditions.
Preparing of working solutions:
The necessary quantity of SHERISOFT SS is diluted with constant agitation up to a ratio of 1:10 (only with warm water 30 - 40 oС). The homogenized concentrated solution is then added to the bath.
If alkaline water is used for preparing the basic solution, pH should be preliminary adjusted to slightly acid reaction by adding of 1 g/l 30% acetic acid.
