Spunbond

SPUN BONDING TECHNOLOGIES

Industrial mono and bicomponent spunbonding lines are under operation and their products are already well-established in the european markets.

The available configurations of the lines do vary from single to multi beam, either for spunbond and for meltblown, from single S to SSMMXS. Therefore, the full range of the market demand, beginning from hygienic to geotextile field, is covered at its whole scope. For the installation, the lines do not require any special pre-preparation or fitting regarding the building they are being used inside and no extraordinary axcavation works or pits are necessary to erect them. There is no need for air to be compressed for the draw and suction in the web forming unit. This is one of the important factors which dropped the energy consumption to levels not have been possible before.

The knowledge once acquired from the construction and start-up of several bicomponent lines has been transferred later on to spunbond lines as well where bicomponents managed to gain a predominant position among the non-woven specialties. Polyolefin (PP, PE) and polyester (PET, CoPET) polymers are mainly utilized for spunbond bicomponent and special spinnerets have been realized according to the sheath-core, side by side and segmented pie profile.

Our spunbond lines produce bicomponent with weight from 8g/m2 having filament count lower than 1 den. Bicomponent spunbond with hydroentanglemend units in line downstream, allows the production of spunlace products having a very high softness, tenacity and bulk. Products having above characteristics are combined in line with other webs, films or pulp to give multilayer non-wovens. Bicomponent spunbond with carded web, bico fibers and pulp can be hydro or air interlaced to obtain other new multilayer products. They can be produced with high throughput and with saving on energy costs, building resources, manpower and without high investment needs. Polypropylene and Polyester (virgin chips or bottle flakes) spunbonds are used in line with needle punching looms and products from 150 to 1000 gsm for geotextile, roofing, building and civil applications. At our facilities, both staple fibres and spun bond bicomponent lines are available for research and development of new products; in accordance to customers’ requests, tailored trials and samples can be manufactured.
