Sherisoft ESHERISOFT E is a universal antistatic-softener, which leaves the treated textile with high level of hydrophilicity and antistatic properties. Especially suitable for:
- Carding and rough grinding of cotton articles;
- Carding of knitwear from polyamid and polyacryl nitrile;
- Softening of textile for baby clothes and nappies,
- Work with organic solvents, due to its exceptional emulsifying capacity in water.
Mixture of condensation products of fatty acids, imidazoline salts and non-ionic surfactants.
|Solubility||Dissolves easily in water at temperature of 25-30 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|
|- to electrolytes||
Electrolitycally stable to NaCl.
Electrolitycally unstable to Na2SO4
SHELF LIFE AND STORAGE CONDITIONS:
At normal weather conditions – 1 year. Avoid freezing. Store away from alkaline products.
А. IN WATER
Sherisoft Е has significant affinity to fibres. It is extracted 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.
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 E:
(fibres, fabrics, knitwear, yarns)
М 1:1 g/l
М 1:10, М 1:20
|Cotton||15 - 30||1,5 - 2 g/l||1,5 - 2 g/l|
|Viscose/ polyester||15 - 30||-||1,5 - 2 g/l|
|Polyacryl nitrile||-||1,5 - 2% of material’s weight||1,5% of material’s weight|
|Polyacryl nitrile/viscose||-||-||2 g/l|
|Viscose - staple, silk||5 - 10||-||-|
|Wool, polyester fibres and blends||20 - 40||1,0 - 1,5% of material’s weight||-|
|Polyacryl knitwear - carding||-||1,5 - 2% of material’s weight||-|
For carding and grinding of cotton textile should be used the maximum concentrations in the table.
These instructions are informative. We recommend being adapted to the specific conditions.
B. IN ORGANIC SOLVENTSPeriodic method of work in drum machines: application by immersion , 5-10g SHERISOFT E per 1 liter solvent, depending on the desired feel and appearance of the textile.
Preparing of working solutions:
А. WATER EMULSIONSThe necessary quantity of SHERISOFT E is diluted with constant agitation up to the desired concentration (with water 25 - 40 oС).
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.
B. WORKING SOLUTION IN PERCHLORETHYLENE
The dose of pure solvent is placed in the drum. The necessary quantity of SHERISOFT E is added. The product dilutes for about a minute, and then it is pumped out in the vessel for pre-processing.
The textile is cleaned. The soiled bath is pumped out. After centrifugation, the textile is processed with the already prepared softener in perchlorethylene (for about 4 minutes). The solution is sent to the vessel for pre-processing and refreshed with additional SHERISOFT E. Thus, it can be used again.
Textile is centrifuged and dried.
Avoid second treatment with perchlorethylene of the softened fabrics.
