Sulfast dyes:
Sulfast dyes are of the conventional class of Sulphur dyes and find their main use in the dyeing of cellulosics and their blends. They are insoluble in water but can be converted into their leuco form using a reducing agent like sodium sulphide, in which state they have a high affinity for the fibre.

Sulfast dyes exhibit good all round fastness properties except for hypochlorite bleaching.

General Application Methods:Sulfast dyes can be applied in the following ways:
1. Jigger Dyeing - Batch wise.
2. Drum Dyeing - Garments.
3. Warp sheet dyeing - Denim.
 
Solfast dyes:
Solfast dyes are water-soluble dyes but having no substantivity. Hence can be applied by the pigmenting system to allow the dye to fully penetrate the substrate by padding (as in the case of woven fabrics) or by package dyeing (as in the case of yarn) and then reduced at a later stage. This helps to ensure better penetration and level dyeing
Application Methods:Solfast dyes can be applied in the following ways
1. Package (Cone or Cheese) Dyeing.
2. Pad Steam
3. Pad Batch
4. Pad Dry Chemical Pad.
5. Warp Sheet dyeing.
 
Texcron Pigment Dyeing System:
The Texcron Pigment Dyeing system is a revolutionary concept, which has been the result of our R & D efforts to provide the garment-dyeing sector with a product range, which is great for fashion. This range provides excellent wash down effects (only pigments can), which are so much in vogue today. The salient features of this system are:

The dyeing system is easy on the effluent!

Excellent wash down effects!

Clean and level dyeing!

Good all round fastness!

Easy to use!

Cost effective!

The application consist of the following steps:
1. Textreat: A process wherein a charge is created in the fabric, providing an affinity for the pigment.
2. Pigmentation: Actual exhaustion of pigment onto the fabric.
3. Fixation: Treating the pigment dyed garments with a specialty Binder and Fixer to provide good Fastness.

Textile auxiliaries

Processing of Textile material involves the use of diverse types of chemicals to perform various functions. These compounds are called Textile auxiliaries or textile chemicals. These chemicals are used in the processing of different substrates and are also used in giving value addition to the processed fabric.

The chemicals can be broadly classified in to three categories like

Enzymes

The trend today is towards garment processing. This is because garment processing offers the processor better and more varied opportunities to add value to the garments in terms of fashionable looks as well as feel. In such a fast changing scenario, Enzymes are playing an important role.
Sulfast Chemical Industries with its indepth knowledge of the Textile and Fashion Industry has a whole range of enzymes to offer to the processor.

Desizing:

This in simple terms is a process to remove the size from the cotton fabric. 'Size' is nothing but the add-on impurities to the cotton fibre to prevent the yarn from breakage during mechanical processing. The most common size ingredients are starch, gums, waxes and some synthetic sizes. Depending on the size composition, various blends of amylases, lipases or proteases are used.

Current Products:
Sulfazyme A5X
Sulfazyme AX

Bio-scouring:

Scouring is the process of removing the natural impurities in cotton like oils, fats and waxes. Conventional scouring involves the use of highly alkaline chemicals like sodium hydroxide and scouring agents, which not only attack the impurities but also the cellulose leading to a reduction in strength of the fabric. The resultant feel of the fabric is also harsh. The load on the effluent is also higher.
Bio-scouring offers an alternative, where the partial replacement with an enzymatic scouring agent provides an environmentally friendly process which also leaves the fabric with a softer handle.

Current Products:

Sulfazyme SCRL

Biowashing/Bio-fading:

The denim garments are given various treatments to impart novel looks. Cellulases play an active role in producing the stonewashing effects, salt-pepper effect etc. Traditionally this is done with the use of pumic stones where the abrasion can also damage the garment. In contrast cellulase enzymes provide the worn-out look in a more gentle manner.


Bio-polishing:

In the wet processing of garments (denim or non-denim, woven or knits), there is a resultant hairiness on the surface of the fabric. Bio-polishing is the enzymatic treatment given to garments to give the following effects:
1. Removes the protruding fibres from the surface by hydrolyzing them.
2. No pilling, or hariness .
3. Provides a smooth and clean look.
4. Imparts a soft feel to the fabric.

Sulfast Chemical Industries has developed a range of enzymes, blended with different activity types to suit various needs.

Current Products:

Sulfazyme BSP, Sulfazyme BCA, Sulfazyme CAL, Sulfazyme DXP/DXPI, Sulfazyme BPL, Sulfazyme NP pdr, Sulfazyme NL liq., Sulfazyme SPG pdr Sulfazyme FDX pdr, Sulfazyme BSR etc.

Peroxide Killers:

Residual hydrogen peroxide must be removed from the fabric after bleaching treatments, which would otherwise be detrimental to subsequent processing. Catalayse enzymes can be used to work specifically on residual peroxide as an anti-oxidant breaking it down into natural elements of water and oxygen without adversely affecting the fibres or dyes.

Current Products:

Sulfazyme APN

Tinting enzymes:

Sulfast Chemical Industries has successfully developed a range of various tint enzymes that do the dual work of bio-washing and tinting in a one-step process. These enzymes incorporate the use of natural dyes and surprisingly offer good fastness as well.

Current Products:

Sulfazyme TNZ series.
