Soft Wool Winder

Soft Wool Winder – The aim of this test is to establish whether a fibre-level dyeing can be achieved with a given levelling agent. The test is primarily important for the Lanasol (reactive dyes for wool). It is similar to  Deep Dyeing

Determination of the levelling and retarding power of levelling agents with reactive and special wool dyes

Principle         

Lanaset ( specially selected dyes for wool ) ranges. It can, however, also be used for other dye classes with due allowance for the relevant recipes and application methods.

Retardation of dye uptake and fibre levelness (root / tip) are assessed visually.

Procedure      

Reactive dyes

Substrate Australian wool, ( No. 3-1004 ). The material is wetted hot and left to cool overnight in the standing bath.  
Dye 2%            Lanasol Red G  
Chemicals   4%            ammonium sulfate pH 5 – 5.5 adjusted with acetic acid 80 %  
Auxiliary 0 – 1 – 2 %                    (higher amounts if necessary)  
Liquor ratio 40 : 1, de-ionized water  
Apparatus AHIBA dyebath or VISTACOLOR ( dyeing basket )  
Method Batchwise exhaustion as follows :

Important The pH must be checked before and after dyeing (pH meter).  If there are nmarked variations, the test series must be repeated. The liquor lost by evaporation during dyeing must be made up with de-ionized water adjusted to pH 5.5.  
Aftertreatment After dyeing, the wool is taken out of the bath and left to drain. It is then aftertreated in a fresh bath (liquor ratio 40 : 1) at pH 8.5 (adjusted with ammonia) for 15′ at 80°C, rinsed and neutralized with formic acid 85 %.
Exhaustion test The exhaustion test shows whether a product retards dye uptake.
Apparatus   AHIBA Texomat
Substrate   Liquor ratio 5 g wool test fabric, chlorinated    ( No. 3-3008 )   40 : 1
Assessment After it has been rinsed and dried, the dyeing is assessed for fibre levelness (root / tip), and retardation of dye uptake. To assess a levelling agent, parallel dyeings must be carried out, one with a known reference product and one without levelling agent   Albegal B is the state-of-the-art reference product for use with reactive dyes for wool.

2.         Lanaset dyes

Substrate Australian wool,( No. 3-1004 ). The material is wetted hot and left to cool overnight in the standing bath.  
Dyes 0.75%  Lanaset Yellow 2R 0.65%  Lanaset Orange R 0.48%  Lanaset Gray G  
Chemicals   1          g/l        sodium acetate cryst. 5          %         Glauber’ salt anhyd.   pH 4.5 adjusted with acetic acid 80 %  
Auxiliary 0 – 1 – 2 %                   (higher amounts if necessary)  
Liquor ratio 40 : 1, de-ionized water  
Apparatus AHIBA dyebath, VISTACOLOR or TURBOMAT  
Method Batchwise exhaustion as follows  :
Important The pH must be checked before and after dyeing (pH meter).  If there are nmarked variations, the test series must be repeated. The liquor lost by evaporation during dyeing must be made up with de-ionized water adjusted to pH 4.5.  
Rinsing Rinse with running warm and cold water.
Exhaust test The exhaustion test shows whether a product retards dye uptake. Procedure as for Lanasol dyes.  
Assessment     : After it has been rinsed and dried, the dyeing is assessed for fibre levelness (root / tip), and retardation of dye uptake. To assess a levelling agent, parallel dyeings must be carried out, one with a known reference product and one without levelling agent   Albegal SET is the state-of-the-art reference product for use with Lanasol dyes.
