Bed Sheets (床单)

Basics

High-end bed sheet fabrics consist of 100 % Cotton or 100 % VIS (Modal) fiber.
Bed sheet fabrics made from 100 % PES or PES Microfiber are also available.
Low budget fabrics are made from Polycotton (Cotton/PES blend) or 100 % PES
Bed sheet printing must produce good penetration to avoid wearing effects caused by yarn twist.
Especially for institutional bed sets, high wash fastness incl. chlorine bleach fastness is required.

Printing methods

Machines are available in 1,800, 2,600 or 3,200 mm working width, to cover the various bed sizes used in different markets.
Mostly an eight-color setup is used.
For highest productivity and most economical printing, double CMYK setup is available, which will double the print output.

Printing on cellulose fabrics

Cellulose fiber based fabrics can be printed with Reactive, VAT dye or Pigment inks.
Reactive prints are known for brilliant and bright print results with good washing fastness, but have a limited light fastness, especially with red shades.
VAT dye inks have excellent light and wash fastness properties, incl. chlorine bleach. For real high-end fabrics, VAT dye inks are the best solution.
Pigment inks are good for high light fastness, but have poor haptics and a low resistance against dry and wet rubbing.
Widely used at public and professional institutions (hotels, hospitals, etc.).

Printing on PES and PES microfiber fabrics

On PES and PES Microfiber fabrics, direct disperse and direct sublimation inks are used.
PES inks have excellent light, rub and wash fastness.

Printing on blended fabrics

Pigment prints are suitable for fabrics blended from cellulose with synthetic fibers; they offer good light fastness properties.
Although the printing process is easy, costs are still high, because special post treatment is required to achieve reasonable dry and wet rubbing fastness.
To improve the haptics, mechanical finishing is required, which adds on the processing costs.

Printing Process

Reactive printing

Fabric pre-treatment with inkjet printer
Design printing with COLARIS.TEXTILE PRINTER
Offline ink fixation through steaming process
Post-print washing to clear the fabric from unfixed dyes and pre-treatment chemicals
Final fabric finishing according to the customer's individual needs

VAT dye printing

Inline pre-coating with thickener to avoid color migration
Design printing with COLARIS.TEXTILE PRINTER (4-8 DyStar INDANTHREN inks)
Drying at about 110 - 130°C (230 - 266°F)
Offline fixation process
Final fabric finishing according to the customer's individual needs

Disperse and direct sublimation dye printing

Fabric pre-treatment with inkjet printer
Design printing with COLARIS.TEXTILE PRINTER, using with direct disperse or direct sublimation inks
Post-print drying - inline right after printing
HT steam fixation in a loop steamer for 8 to 10 minutes
Reductive washing and vacuum extraction for high light and rubbing fastness

Option: Inline inkjet pre-treatment applied by the CHROMOJET digital pre-coating unit
Option: SUPRAPRESS penetration support
Option: Inline fixation for about 4 minutes

Printing Lines

For high-capacity printing output we recommend COLARIS.TEXTILE PRINTERS with FUJIFILM Dimatix StarFire™ print heads.
The ReadyJet™ ink circulation system guarantees permanent ink availability under any working condition.
The ink circulation system avoids the sedimentation of solid ink particles. This is important especially when printing with VAT dyes or Pigment inks.
The COLARIS.TEXTILE PRINTER concept allows a flexible layout according to the requirements of the various ink and dye classes.
The open ink system allows to select from several ink manufacturers available in the market.
