Our machine park and process

Bethge AG owns the most modern machine park in Europe, which includes all finishing processes for cotton processing or their blends in the textile industry.

The demands on textiles are diverse. Whether elegant sheen, special weave structures or heat-resistant properties with the highest level of comfort : we refine textiles for our customers according to their wishes.

The following methods are available to give your textiles the properties you need. These can be combined as required. Our experts will be happy to advise you in order to develop the optimal manufacturing process for you.

Textile finishing processes

Preparation of raw materials

Our spacious high bay warehouse offers sufficient space for both raw and finished goods. The high shelves with numerous pallet spaces ensure optimal use of space. The raw material goes from the high-bay warehouse to assemble the batch. The goods delivered by the customer are prepared and put together for the subsequent processes. The storage space in our high-bay warehouse is made available to our customers free of charge

Washing and dyeing

Fabrics are washed on the wide washing machine. Washing is very important in finishing and depends on various factors. Washing removes dirt, other impurities and weaving oils. Bleaching destroys the natural color of the goods, giving them a higher degree of whiteness. In addition, the goods become more absorbent.

Fabrics that are not subject to creases are dyed in the jet dye machine.The jet dyeing machine dyes in the thread, which means that the fabric is not stretched in its natural width during the process.This process has the advantage that the fabrics are not under longitudinal tension during the dyeing process

In the jigger the tissues can be guided in a wider position, they can be stretched over their whole width. This dyeing machine is therefore suitable for goods that are sensitive to wrinkles. In addition, there is the low liquor ratio (FV = 1: 3 to 1: 5). The jigger is not only suitable for dyeing but also for boiling, bleaching and washing.

The cold pad process (KKV dyeing) is a process in which the goods pass through a padder in which the dye liquor is located. After the foulard, the goods are wound up on a dock and left at a dwell station, where they remain until they are evenly dyed and fixed. The dyed goods are then washed out and dried.

Chemical equipment

When singeing the fiber ends that stick out from the textile goods are burned off.This reduces both the tendency to pilling and the tendency towards soiling. The result is a smooth, lint-free surface. The scorching machine has several gas flames, which are in different positions in relation to the direction of movement of the goods. The goods run past the open gas flame over several rollers.

After singeing, the goods are desized. Desizing is a process in which the so-called size is removed from the fabric. The size serves to improve the running properties of the yarns during the weaving process. However, it must be removed before further refinement processes.

The mercerizing process takes place on the so-called mercerization system. The cotton is treated with caustic soda under tension in order to change the cross-section of the cotton. The naturally kidney-shaped cross-section of cotton becomes almost round as a result of this structure-changing treatment.This creates effects such as improved dimensional stability, washable gloss or a higher ability to absorb dyes and chemicals.

The tenter frame is an irreplaceable system for several tasks.With the tenter frame, the goods can be dried, fixed, impregnated, leveled and even coated with an additional component. The principle of the tenter frame works like an oven. There are several fields that can be heated to any temperature. It also has a lower and upper ventilation to extract any vapors.During heat setting or ramming, the internal tensions are eliminated and the goods are straightened with a warp thread. Wet goods can then be dried directly.

When impregnating chemicals are used to positively influence the properties of the goods, such as the water repellent effect.

Coating like the impregnation influences the properties of the goods. When coating, however, only one side of the goods is processed per pass.This creates waterproof, windproof, flame-retardant or among other things water repellent properties

Mechanical equipment

During calendering, the fabric is pressed using pressurized steel or rubber rollers. The effects that result from this depend on the speed of the goods, roller pressure and roller surface. The result is a glossier, smoother and denser product.

The sanding machine has several rollers which are covered with a sanding belt. These rollers can move with and against the direction of movement of the fabric, so that an optimal sanding effect is created. The task of the sanding belt is to lightly sand the goods so that a velvety surface results.

This equipment has the task of lifting or extracting the fibres of the fabric threads, which creates a bulkier, softer and more insulating structure.The raising machine has several rotating rollers, which are covered with a rubber stocking and contain slightly curved needles. The rollers can move with or against the direction of movement of the goods. The voluminous effect of the roughening ensures that the goods retain their warmth.

Shrinking is used to prevent the tissue from shrinking in later use during the wash.Articles that have not been shrunk could shrink when they are washed or ironed with steam, making them unusable. This process is important for fabrics that should guarantee a residual shrinkage of less than 4%

Final presentation

The edge printing machine can use a stamp and a foil to print any stamp motif on the edge and thus on the goods. Thanks to the moving printing table this process can be carried out continuously.

At the inspection machines the fabric runs over several rollers and then over an illuminated plate, which makes it easier to identify weaving errors or other defects such as stains and holes.Only when the goods have been fully inspected are they released to the customer.

Bethge AG has various options for the presentation of finished products.The goods can be rolled, wrapped on sticks, doubled or stretched.After the finished products have been presented and approved by the customer, they are taken to the shop.The finished fabrics are stored in the prefabricated warehouse until they are collected for transport.
