Transfer Printing


Transfer printing was discovered in 1957 by a gentleman called NOL DE PLASSE who worked for the company LAINIRE DE ROUBAIX in the North of France.

He understood that the dyes could pass directly from a solid to a gaseous state when brought to a temperature above 190C (370F). This change is termed sublimation and is the basis of transfer printing, also known as dry printing.

Synthetic fibres for transfer printing.

The most popular fibre for transfer printing is polyester.

Polyester blends, Nylon 6.6, Acrylic and triacetate can be printed as well.

A transfer printing calender is the most popular way to perform this process. The calender has a heated cylinder around which the fabric to be printed is passed. The fabric is supported by a continuous blanket giving a close sandwiching of the paper between the fabric and the heated cylinder. This then allows the transfer of heat to both the fabric and paper and the paper to release the disperse dyes to sublimate.

The cylinder radius and its contact with the sandwiched paper and fabric gives a dwell time to the process. Obviously the sublimation process takes a certain amount of time to occur and it is generally recognized that the optimum dwell time to achieve complete exhaustion of the disperse dyes onto the fabric is in the range of 15-30 seconds.


Advantages of transfer printing


As once can see the process of transfer printing for the fabric printer is very simple, all the problems of printing the design in the first place are given to the transfer paper manufacturer. What are the other advantages :
- Capital investment is low compared to other printing processes
- No auxiliary equipment
- Small floor space required
- No pollution or effluence
- Efficient energy consumption
- Clean process with limited machine maintenance
- Minimum semi skilled labour required
- Limited stock of printed cloth
- Transfer paper readily available from numerous
   manufacturers worldwide
- Sample paper lengths available in 5 meters
- Immediate change over from design to design on the calender
- Ability to rapidly respond to clients demand

LEMAIRE calenders are renown for their reliability and for their innovations. We manufacture a range of machines with different cylinder diameters denoting the speed of production. Furthermore, we offer a variety of working widths from 1800 mm for standard fabric to 3200 mm for wide width fabrics and sometimes up to 5000 mm for floor coverings.

 The Double Dispensing System (D.D.S.)

This system is designed to permit synchronized wide width transfer printing up to 3.20 m of various substrates (non woven materials, films, woven fabrics, warps) using two rolls of heat transfer papers of the same design and matching these designs across the width.

There are 2 dispensing units controlled independently.

Each one features
- an air expanding shaft
- 2 mobile bearing housings
- One pneumatic brake controlled by a precision valve
- A positive drive assembly for lateral movement of the

The two heat transfer paper rollers are guided :

- laterally by 2 photo-electric cells for the paper edge
- longitudinally by a photo-electric cell to read the
  registration marks on the edge of the paper (to join the

The information read by the photoelectric edge guidance system is transmitted to the microprocessor control, which analyses and activates the correction movements of the assembly along the width or the length appropriately.



 Warp Transfer Printing

The LEMAIRE process of warp transfer printing can be applied to a wide range of yarn counts, although the best results are achieved when printing 100 to 300 denier polyester.
The yarn can be filament, texturized spun, etc.

Of course, a precise control of tension and alignment is crucial to maintain the warp quality. The warp printing machine is a beam to beam system. The specially designed control system monitors and maintains level tension between let-off and printing, and again between printing and rerolling. Alignment is also monitored by a photoelectric system.

The advantage of warp printing is that from one warp print an infinite number of designs can be produced. Firstly you may vary the weave on the warp to change the fabric. Secondly you can vary the colour of the colours in the filling therefore giving different colourways and bring out different hues in the warp print. Thirdly you can vary the type of yarns used in the filling, inserting fancy yarns etc.


 Pile Fabric Printing


One of the great interests currently is the possibility to print the pile fabrics such as flocked or velours fabrics. The "coupling system" available on LEMAIRE machines eliminates excess pressure and torque which otherwise cause the pile fibers to lie down. A dense pile of less than 4 millimetres (0,16 inches) pile height gives the best results.

Longer dwell time, not higher temperature is important for thorough penetration. Brushing up is also helpful to regain pile height.
