Textile Printing Thickener for Reactive dyes

1) Tamarind Kernel Powder (TKP)

2) Carboxyl Methyl Tamarind Powder (CMT-8)

Process of TEXTILE PRINTING, using Tamarind Powder as thickening agent:-

Tamarind seed gum or tamarind kernel powder (TKP) is derived from the seeds of

Tamarindus Indica Linn. It grows in more than 50 countries of the world. The major areas of production are in Asian countries like India, Bangladesh, Sri Lanka, Thailand, and Indonesia, and in the African and the American continents.

Tamarind seed gum is a high molecular weight polysaccharide which forms viscous solutions when dissolved in water. 

Tamarind seed powder is produced as a byproduct of the tamarind seeds through a very complex process that entails the following:

• Harvesting: Upon maturity, the pods or kernels are harvested from the mature        tree

• Sorting: –The harvested pods are broken open to remove the seeds which are          further separated by removing rotten seeds, debris, stones and keeping the good      seeds.

• Roasting: The Good seeds are passed through heat which roa process makes the      seed coat brittle while having little effect on the endosperm.

•Stripping: After the roasting process, it becomes easy to the endosperm through a   process referred to as stripping. 

•Grinding: The endosperm isgroundthento separatemilledthe endospermor from the   germ hence creating the tamarind kernel powder.

•Screening: The tamarind seed powder is further screened to which is later mixed       with a solvent to form Tamarind gum powder.

A full grown tamarind tree usually yields between 175 and 250 kilograms of kernel/seed. Further, the kernel of the seeds is separated by color sorters and then methodically grounded to make tamarind kernel powder.
