Textile Sector

In textile printing, method selection depends almost entirely on the fibre structure of the fabric. Polyester and cotton interact with dye in completely different ways, so there is no single "best technology" in this sector — there are two main routes that change with the fabric being printed.

The first is sublimation: under heat the dye turns to gas and penetrates the polyester fibre. The second is DTF: the image is printed onto film, coated with powder adhesive and transferred to the fabric with a heat press. Sublimation works only on light-coloured polyester, while DTF also delivers results on cotton and dark fabrics.

Applications in textile printing

Flags and pennants

Sublimation is the standard method for pole flags, hanging flags and exhibition pennants. On products seen from both sides, double-sided printing prevents the reverse face from appearing mirrored or faded.

Sportswear and jerseys

On polyester jerseys, sublimation printing does not compromise the breathability of the fabric. Because the dye forms no layer on the surface, the print cannot be felt and does not crack when stretched.

Promotional textiles

For t-shirts, bags and caps the fabric is mostly cotton and dark colours are common. This is DTF's natural territory; thanks to the white underbase, colours stay vivid even on black.

Choosing a machine for textile printing

If your production is polyester-based, sublimation printing machines are suitable; if you work with cotton and dark fabrics, DTF systems are. In flag production, models with integrated fixation complete printing and setting in a single flow, removing the need for a separate calender press.

Frequently Asked Questions About Textile Printing

1. Why does sublimation not work on cotton?

Sublimation dye bonds chemically to polyester fibre. Cotton is a natural fibre and cannot form that bond, so the dye washes out. DTF is preferred for cotton products.

2. Does the print fade in the wash?

In sublimation, fading is minimal because the dye penetrates the fibre. In DTF the print forms a film layer on the surface; a correctly applied transfer withstands dozens of washes.

3. When is double-sided flag printing needed?

It is needed for hanging flags and pennants seen from both sides. For products viewed from one side, such as table flags, single-sided printing is sufficient.

4. Is the fixation process mandatory?

In sublimation it is; the dye only penetrates the fibre under heat and pressure. This is done with an integrated fixation unit or a separate calender press.
