Application

CMT - 8 is a textile printing thickener specially developed for printing on polyester with disperse dyestuffs followed by superheated steam fixation (170 - 180oC). This thickener is also suitable for the thermosol process. It is not recommended for premetalised and acid dyes.

It displays excellent stability in presence of auxiliaries usually used in printing on synthetic except bi- or trivalent metallic salts. The thickener is compatible with disperse dyestuffs as well as with anionic and non-ionic products.

It is specially suitable for the rotary printing process, due to its high-grade purity. The excellent flow properties of CMT - 8 paste meet all the requirements of the different printing machines.

Solubility

CMT - 8 is cold water soluble. The use of a high speed stirrer or of a dissolving station is necessary to prevent the formation of lumps. After a swelling time of at least one hour, the stock thickener is ready for use. A longer swellingtime of up to 12 hours will improve the flow properties and homogeneity. Dissolving in warm water or boiling iseasily possible and provides aneven better homogeneity of the stock paste.

Colour Yield

CMT - 8 provides very good transfer of dyestuff to the fibre by conventional super heated steam fixation process.

Washability

Due to its special modification, can be washed off easily even after a previous superheated steam fixation. Perfect removal of the thickener is achieved resulting in a soft handle of the printed fabric and brilliant shades.

Preservation

CMT - 8 contains preservatives. The viscosity of the printing pastes and stock thickeners shows good stability over a long period.

Storage

Good storage stability when kept in the unopened packaging in a cool and dry place.
