BASIC TECHNOLOGY

BASIC TECHNOLOGY

NEEDLE PUNCHING

Vpichování (15)
Vpichování (7)

PRINCIPLE

Out of the input material (fibre staple) a layer of fibres – web – is created mechanically by means of a carding machine. A mat is made by placing several layers of the web by means of a lapper. The mat is then taken between two perforated plates, with needles going through the openings. The needle barbs catch bundles of fibres, turn them perpendicularly to the direction of the material passage and pull them through the mat. When the needles move backwards, the fibre bundles slip out of them and entangle with the adjoining fibres. With the needle punching process, the fibrous mat becomes stronger, thinner, and if required merges with the underlay (fabric, foil, etc.).

TECHNICAL PARAMETRES

Processed material = PP and PES staple fibres, recycled fibres
Working width = 4 - 6,5 m

BASIC TECHNOLOGY

AIRLAY

0313
Airlay (5)

PRINCIPLE

The Airlay technology creates a structure – a textile with randomly oriented fibres entangled with binder. The input materials are mixed in an aerodynamic chamber. The layer thus created is then placed on a perforated belt and conveyed into a thermal chamber where as a result of the heat and pressure applied by the upper belt the binder is melted and the layer is compressed to the required thickness. At the end of the line, the created textile is formed into the shape of sheets or rolls.

TECHNICAL PARAMETERS

Processed material = polyester fibres – PES, polypropylene fibres – PP, mixtures of synthetic and natural fibres, recycled fibres – natural and synthetic fibres and recycled textiles

Weight = 600–6000 g/m2

Product thickness = 5–200 mm

CHEMICAL AND HEAT TREATMENT

CHEMICAL AND HEAT TREATMENT

FOAM IMPREGNATION

Technologie_Chemická úprava_ (4)
Impregnace pěnou (2)

PRINCIPLE

Chemical treatment of nonwovens in order to reinforce the fibrous layer or to achieve the required characteristics of the textile. The treatment involves impregnation – application of a foamy binder and its processing into the textile structure. Foam may be applied to one or to both sides of the textile. When foam is applied from both sides, a different type of binder or treatment can be used on each side. The impregnation process is completed in a hot-air chamber where the applied binder and finish are activated. When the textile is cooled down, it is formatted to the required width and shape, into a sheet or roll.

CHEMICAL AND HEAT TREATMENT

POWDER COATING

Práškování (2)
Práškování (3)

PRINCIPLE

Chemical treatment of nonwovens to reinforce the fibrous layer, to apply an adhesive layer or to connect two materials by applying thermoplastic powder binder. The binder is activated in a hot-air chamber. When the textile is cooled down, it is formatted to the required width and shape and cut into sheets or rolled up.

LDPE or HDPE powder binder
PE foil

CHEMICAL AND HEAT TREATMENT

CALENDERING

G_Technologie_Kalandrování

PRINCIPLE

Reinforcement of nonwovens by heat and pressure where such reinforcement takes place in the slit between two rollers by heating and compressing the nonwoven textile. Heating softens the fibres and as a result of pressure, binding places are created between fibres. Subsequent cooling reinforces the bond.

VELOURING AND SHEARING

Postřihování (3)
Postřihování

PRINCIPLE

Mechanical treatment of needle-punched nonwovens, which delivers a uniform surface. It gives the textile the look of velour or suede. Characteristic features of such products include a smooth touch and velvety surface.
