Pre - treatment of Modal fabrics?

Viscose and Modal fibers are supplied in the pure state and with an incomparably higher degree of whiteness than cotton. Bleaching processes are, therefore, only required for completely white products (reduced quantities of chemicals) or pastel shades.
While tending to be unaffected by the usual chemical concentrations, viscose and Modal fibers react rapidly and intensely on coming into contact with alkali. Both fiber types are capable of being activated by a lye concentration of 4.5% (7°Bé) to such an extent that a distinctly higher dye absorption results.

While a concentration of 4.5% NaOH (7°Bé) represents the upper limit as far as viscose fibers are concerned, Modal fibers can, leaving aside the critical range of 7% to 15% NaOH, be treated with mercerizing lye of 17% to 22% (24–28°Bé). For bleaching products the temperature should not be allowed to exceed 180°C, e.g. heat-setting of blends with PES. Prior to thermal reaction, the fibers must be generally free of alkali residues.

Pre - treatment receipe for white products:

Setabicol BAC :6 g/L

Setalub ACA :1 g/L

Hydrojen Peroxide (50%) :4 g/L

Temperature : 90 - 98°C

Time : 45 - 60 min.


Note: Creases can occure if material is wet and wait. Centrifugal machine should not be used at any stage and it must be dried immediately after all wet processes.

* 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.
