Polyester important as digital textile printing grows

With the global digital textile printing market expected to show an unprecedented 18.29 per cent CAGR between 2017 and 2021, use of polyester is likely to grow. This is because printing on synthetic fabrics is a lot cheaper than printing on natural fabrics, according to the report ‘Global Digital Textile Printing Market 2017-2021’, by Research and Markets.

Polyester is the most eligible synthetic material endorsed by digital printing experts.

Priscilla Wilson, principal director, Exhibit Express, explains the hows and whys. “Polyester is preferred for digital textile printing, owing to its high durability, resistance and strength bettered by low shrinkage and colour fastness”, says Wilson. “Being sensitive to heat, polyester can be manipulated effortlessly with high temperature and pressure to create permanent pleats and laser cuts”, she adds.

Polyester is also preferred for large format soft signage or custom display printing. Polyester 210gsm is widely used in wall graphics, textile banners, table throws, flags and tension frame systems frequently used in tradeshow booths.

Talking about the best method to print on polyester, Wilson says, “Ordinary dyes cannot alter the colour of polyester due to its high stain-resistance. We need disperse dyes to create the expected results. To minimise dye migration, we use a white or grey ink as a base before applying any other colour. The dye-sublimation method of printing reduces wastes.”

“The best thing is that digitally printed sublimated polyester both can be washed and then tumble-dried in a low-temperature setting. This is another reason to choose polyester”, she concludes.

The trade show display printing market will continue to depend on polyester. As more trade fairs are organised, the demand for the fabric will escalate.
