The figure below shows an inside view of the Dye Beck.





Beck dyeing has evolved as a very good method for dyeing of carpet pieces or rolls. Beck dyeing essentially is the Batch method. A beck dyeing operation to be successful must commence in the dye lab itself. In the laboratory a formula or dye recipe is prepared for each of the colour before the carpet is put into becks. Beck dyeing in simple terms is just placing of the carpet in a big vat consisting of hot dye and in a way to cook it for a few hours. Dyeing this way is able to put the color uniformly through out the carpet. This is also the best method for ruling out the problems associated with sidematch. Beck dye carpets Can be a bit expensive as they involve a comparatively longer time.

Liquor Ratio- The ratio of the liquor to goods that is used in becks typically stands out at 15:l or some times even higher.

Dyeing Temperatures- Tempearures upto 100^oC can be employed for dyeing with atmospheric Becks.

Time Duration- Just as the dye is natural that does not guarantee that it is also environmentally sustainable. For example pesticide may have been used to grow the crops etc.

Crucial role of pH- pH plays a vital role in the beck dyeing process. pH controls strike rate, absorption rate of dye, dye exhaustion etc.

• The greatest advantage of beck dyeing is the modest pricing, simplicity, and versatility.
• In Beck dyeing fabrics are subjected to comparatively low lengthwise tension and helps the development of fabric bulk and yarn crimp.
• The process Beck dyeing is an effective way to totally rule out any risk of sidematch problems a common problem with dyeing of carpets.
