TFC : Cotton Yarn Dyeing.

In collaboration with CIBA SPECIALTY CHEMICALS, SUPERBA has developed a new process of continuous dyeing on pure and blended cellulose-based fibers. This process, known as TFC (initials of cotton yarn dyeing in French), allows a large range of fashionable effects to be achieved and yarns in all colours to be produced for denim fabrics.



Advantages of this technology:

The TFC process presents a lot of advantages :

CADM (computer-aided design and manufacturing). Colours and effects can be simulated on computer with special software which automatically defines the application methods and calculates the machine adjustments. The screen display permit time saving in respect of both designing and achieving the end product.



High manufacturing flexibility and cost reduction. A very wide range of effects can be obtained on the same machine including chiné, jaspé, washed-out looks, mono or polychromatic dyeing, ring dyeing and denim type yarns. All these effects can be combined or superimposed on one another. It has been established industrially that an up-market item woven with autoclave dyed yarns, then chemically piece washed-out, costs up to 3-4 times more then the same item produced on the TFC process.



Environmental protection. The high fixing rate obtained with this technology gives especially high fastness and minimises the amount of dye in the waste water.

This process has been studied to conform with European standards regarding machine safety and environmental protection regulations.
