  5.Direct printing on polyester with results like discharge printing
Using the dyeing auxiliary Polyster TMC-200

According to the printing consultant N. Oyabu (originally of Daido-Maruta Finishing), the direct printing of polyester can now produce a motif as fine as that of discharge printing. To produce motifs in direct printing like those in discharge printing, the dyeing auxiliary Polyster TMC-200 is required.


N. Oyabu's explanation is as follows.

Polyster TMC-200 can protect against certain deficiencies.

In the printing of polyester, traditional methods, being hydrophobic, have good penetration which can result in the dyed patterns being blurred, leading to quality problems.

Because bleeding is totally prevented with TMC's newly developed product through printing in one operation, 70-80% of motifs produced by discharge printing can now be produced by direct printing. TMC-200 is a special dyeing auxiliary that allows the production of motifs with extremely fine lines and designs with the look of discharge printing, thus facilitating the production of excellent high-quality products.

This auxiliary is effective because material treated with TMC is cationic and the disperse dyestuff of printing paste is anionic, and so bleeding is stopped by the cations and anions combining.

This auxiliary can also be added to printing paste, but due to pigmentation, problems can arise under certain conditions.

TMC is free of problems relating to the specking of the dyestuff and has a solid track record, being used in a large number of factories in Southeast Asia, including Indonesia, in the production of high-quality products with motifs like those of discharge printing.

3.Cost Price and consumption rate

Taking the padding method as an example, one kilogram of Polyster TMC can treat 3400 yards of fabric 44" wide, or 2500 yards of fabric 58" wide, the average length that can be treated being 3000 yards. (See Fig. 4) There is a materials cost for TMC, but it is not high.

58" x 2,500Y

In addition to the rationalization of productivity, increased efficiency, and increased printing density for the paste and the mesh, this treatment can produce sharp designs and high-quality processing like that of discharge printing. Because the total cost will definitely be lower, the use of TMC is recommended.
