GROUPS OF TECHNOLOGIES
We make nonwovens for indoor and outdoor use by means of modern machinery and technology – needle punching lines, airlay, chemical treatment lines, surface finish lines for velouring and shearing, powder coating lines, cutting and formatting machines.
BASIC TECHNOLOGY
NEEDLE PUNCHING
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
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
FOAM IMPREGNATION
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.
PROCESSED MATERIALS
Needle-punched nonwovens
Latex binders
TREATMENT FUNCTIONS
Non-flammable
Flame retardant
Velcro resistant
Reinforcement of the fibre layer
CHEMICAL AND HEAT TREATMENT
POWDER COATING
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.
PROCESSED MATERIALS
Nonwoven textile
LDPE or HDPE powder binder
PE foil
CHEMICAL AND HEAT TREATMENT
CALENDERING
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.
PROCESSED MATERIALS
Needle-punched nonwovens
MECHANICAL TREATMENT
VELOURING AND SHEARING
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.
