* How to strip Turquoise dyed cotton material?

15,00 g/L Hydrosulphate
6,00 - 7,00 g/L Caustic Soda
3 g/L Setalan IW

95C, 20 - 30 minutes.

Note: Please make a trial in laboratory before application in the bulk.

* What are Exhaustion curves of Setazol Yellow 3RS, Red 3BS and Blue BRF? What are important fastness properties of Setazol Blue BRF?

- Three dyes has very close Exhaustion curves and therfore this combination obtain level dyeing with good reproducability,

- Setazol Blue BRF has high light fastness in 1/1 depth is (6),

- Setazol Blue BRF has lower Chlorinated Water (3) and Gas fastnesses (3).

* If requirement for shrinkage of Viscose knitted fabric is less than 5%?

a) If requirement for shrinkage of Viscose knitted fabric is less than 5%, it should be used a Free Steam dryer instead of normal stenter. After free steam dryer, material should be sanforazed in a sanforization machine.

b) Material should be in the Process as following;

- Weak Cold Caustification (it can help for better size stabilisation and less creasing of the fabric)
- Dyeing,
- Open width free steam dryer,
- Sanforization.

* How to strip Setasil 64?

The test must be carried out firstly in laboratory conditions in order to see change of the color.

There are 3 alternatives;

1. 12 g/L Setalan OSK - N + 8 g/L Caustic Soda 48 Be, 98 C de, 48 min.

2. 10 g/L Setawash L400 + 10 g/L Soda Ash, 98 C de, 48 min.

3. 6 g/L Setalan OSK - N + 4 g/L Caustic 48 Be, 98 C de, 48 min.

* How to wash HT Machine effectivly?

1. Guide Fabric :It can be an old and un – useful 100% PES fabric. It has to be used because to run in the machine and collect dirties to itself.

2. Machine :Machine have to be full filled by 2/3 water.

3. Chemicals :

3 – 4 g/L SETALAN OSK – N - It is using to remove olygomers.
5 – 6 g/L Hydrosulphite or 2–3 g/L Reduktan AN - Reduction Agent
10 g/L Caustic Soda - To have necessary Alkali condition.
2 – 3 g/L Setawash BNH - It is for creating foam. Foam have to be used for penetration of the chemicals to all parts in the machine.
2 g/L Setacarrier HT - Its for migration of the dyes from one place to other place.

5. Temp. :at 135C, 45 min - 1 hour.

4. Drain :After finish the washing, water have to be drain as hot as possible.

* How to dye fabric for man suiting: Warp: CDP/Rayon, 70/30 - Weft: 1) CDP/Rayon,70/30 2) PES,DTY fabric?

The process is:

1. Pre - washing:

1 g/L Setabicol BAC, 80C, 20 minutes.

2. Rinsing
3. Nutralisation with A.Acid
4. Dyeing in one bath CDP/PES:

* Disperse dyes :Setapers CE range dyes
* CDP dyes :Setacryl Golden Yellow GL, Red FBL, Blue FGRL and Black FDL (for Black) - Setacryl dyes must be dissolved very good with addition of A.Acid with bioling water and part from IK-200.

* How to pass from WICKING AND DRYING TIME TESTS?

1) For PES/Co fabrics ;

a) After finish the dyeing and washing of PES and Co material, adjust last bath (Softeneer bath) to pH 5,5 with Setacid NV-C, than add 2% SETASOFT AQUA-ESF to the same and re - check for pH to be 5,5. Application should be carried out at 70 C, 15 minutes. pH have to be adjusted with Setacid NV-C instead of asetic acid.

b) After above application, the padding bath in the drying stenter should be adjust to pH 5,5 with SETACID NV-C, than 1add 100 g/L SETASTAT TM-P and 100 g/L SETASOFT AQUA-ESF
(Pick up :25 %)
Proces is from wet on wet so chemical consumption is more than usual.

c) Drying in Stenter


2) For 100 % Cotton;

a) After finish the dyeing and washing of Co material, adjust last bath (Softeneer bath) to pH 5,5 with Setacid NV-C, than add 2% SETASOFT AQUA-ESF to the same and re - check for pH to be 5,5. Application should be carried out at 70 C, 15 minutes. pH have to be adjusted with Setacid NV-C instead of asetic acid.

b) After above application, the padding bath in the drying stenter should be adjust to pH 5,5 with SETACID NV-C, than add 100 g/L SETASOFT AQUA-ESF (Pick up :25 %)
