PRINTING AND COATING

Impression transfers to measure of quantity manufacture being able to reach 1500 meters a day.

The team consists of two people this day, Jocelyn Jagot and Frank Beuret. We work on with the continuation Adobe clearly Photoshop and Illustrator.

The process of transfer is simple, grace our equipment of impression understanding a printer Mimaki and a press of factory MS JP4 we can print up to 100 meters of paper transfer per hour.

The major interest of this process is situated at the level of the absorption of the colouring agent by the fabric. He does not adhere on the cotton, on the fabric compound of several fibers as the polyester and tricky, alone the polyester will be printed, which can return magnificent motives.

SANFORISING

The sanforizer is used to remove the warp and werf tensions and reduces the shrinkage. The fabric runs through a machine with drums filled with hot steam. The fabric is given an optimum dimensional stability by applying mechanic forces and water vapour.

All finished fabrics content inner tensions due to all previous mechanical operations (as spinning, weaving, knitting and finishing).

Steaming
The fabric’s humidification allows the fibres to reinflate after drying operation squeezed by through two rolls.

Stentering
A mechanical equalization along the whole fabric’s width (open-width drying) takes place

Compression between the rubber band and the heated cylinder.
The inner tensions are mostly removed.

HIGH TEMPERATURE DYEING

Equipment capacity : from 20 to 400 kg by batch.

The textile is dyed thanks to a discontinuous process (full exhaustion method). Dyestuffs are gradually fixed into the fabric. Some fibres such as PET need higher temperatures.

In a discontinuous process, all kinds of fibres, knittings or fabrics can be dyed. Almost all kinds of dyestuffs can be used (dispersive, acidic, reactive and vat-dyes). Different kinds of machines are dedicated to the discontinuous dyeing:

Material in motion and static batch (Jigger, Winch)

Batch in motion and static fabric (Autoclave)

Both fabric and batch in motion (Over-flow, Air-flow and Jet)

Over-flow: big water ratio
Air-flow: small water ratio, fabrics in rope form
Jet: ventilation system, with rope opening

CHEMICAL FINISHINGS

Chemical finishings usually consists in a deposit of a product on the textile aiming to give it specific properties.

Properties of permanency being often requested, new chemical finishings have been created in order to get real chemical links within the fibres. This permanency is due to the use of reactive chemicals and pre-curable polymers, which form a macromolecular film around the fibre.

Long lasting finishings

These finishings improve the life of the garment and facilitate the textile care operations (washing, drying…). This group consists in reticulation finishings (easy-care, dimensional stabilization…), anti-felting finishings, soil-release finishings, and anti-sleepage, as well as finishings designed to improve the dyeing fastness.

Protective finishings

These finishings intend to protect the textile against its future environment or use (water-repellent or oil-repellent, fireproof, biocide, antistatic…).

Organoleptic finishings

They are directly linked to the people’s sensations, which is a subjective factor. These finishings can increase the fabric’s weight, modify their handle but also improve their softness, brightness or coat them.

Other finishings

Some finishings not listed above can offer other properties such as mechanical improvement, optical brightening, better sewing properties…

A new generation of finishings has more and more success such as microencapsulation of active principles (perfumes, thermoregulation, cosmetics…)

MERCANTILISATION

This process consists in the impregnation of the fabric in caustic soda, maintaining some tension in the fabric. The intern structure is modified.

The primary wall of the cotton fibre gets a rounder shape. As a result, the surface is cleaner and therefore shows a better reflection and brightness. The fabric’s tension during this process improves the tearing resistance and removes the permanent folds of the material.

ETC decided a few years ago the diversification of its activities within the new sector of textile finishing for multi-fibres and technical applications.

Today we are able to offer you:

our expertise in specific finishings for cellulosic fibres,
know-How in finishings for technical fibres,
performance in preparing all supports for digital inkjet printing.

Fabrics, knittings and some nonwovens can be equally worked out. A multi-purpose and high performance machine base enables us to meet your requirements in the textile finishing sector.

SINGEING

Some raw fabrics may show small fibrils on their surface due to friction during the weaving process. They can be easily removed by means of this process. The final fabric gets a better optical and tactile aspect. This process is mainly used for fabrics containing cotton.

Our singeing-machine is equipped with 2 distinctive flames; it’s possible to singe the fabric in 2 different ways: the flame can either lick the fabric directly or indirectly. Only one side of the raw material may be treated on request. The power of the flame is controlled at the exact temperature thanks to a laser sensor.

MECHANICAL FINISHINGS

Brushing/Shearing

Our machine is essentially composed of cylinders (20 or more). They are covered by a tape, on which hardened-steel head needles are positioned. They peel the surface of the fabric. Each cylinder rotates in the opposite direction of the previous one. It is possible to treat the material on either one or on both sides.

In order to obtain a regular fluff, it is necessary for the material to be brushed several times before going through the shearing process.

Emerizing

The purpose of this process is giving the fabric a “peach aspect”. It is frequently done before the dyeing process.

This machine is composed of cylinders covered with emery paper. There are several kinds of emery paper covering the cylinders and they are more or less thick according to their granulometry, and to the requested emerizing level.

PAD-BATCH DYEING

The pad-batch is a cold dyeing process; the raw fabric goes through a batch (composed of dyestuffs and alkali). The textile is then squeezed between two cylinders.

The dyeing process includes three operations:

Fabric padding
•Squeezing (unfixed dyestuff wash-off)
Rolling and rotation of the fabric

The dyeing batch is supplied by a dispenser pump.

Conditioning cabinet

After dyeing, the fabric is packed and stored in a 20°C room and remains in rotation in order to achieve a better impregnation. The time to achieve the fixation is determined by the type of dyestuffs.

Wash off

After rotation, the fabric is washed off in a continuous washing machine to optimize the fixation of the dyestuffs and to eliminate the excess or insufficiently fixed dyestuffs.

ENZYMATIC TREATMENTS

The enzymes used for softening cotton are of cellulose type. They represent all kinds of enzymes able to hydrolyze the cellulose. Enzymatic treatment of the surface and softening of cellulosic fabric consist in elimination of surface fibres. It is then possible to decrease or eliminate the pilosity and the fuzz which are responsible for pilling and slubs.

Moreover, the elimination of the surface fibres improves handle and softness.
