Non Wovens
Condako offers a wide selection of non wovens specially designed for different applications and processes used in the automotive industry. Furthermore, we are able to develop now wovens with the characteristics that will fulfill your functional requirements. The non woven technologies we offer are the following:
- Chembond
- Thermobond
- Needle Punch
- Spunbond
- Spunlace
- Polymers
- Chemical Bonding (Chembond): refers to the application of a liquid based bonding agent to the web. Three groups of materials are commonly used as binders-acrylate polymers and copolymers, styrene-butadiene copolymers and vinyl-acetate ethylene copolymers. The binder can be applied uniformly by impregnating, coating or spraying or intermittently, as in print bonding.
- Thermal Bonding (Thermobond): refers to the use of thermoplastic properties of certain synthetic fibers to form bonds under controlled heating. Usually a low melt fiber or bicomponent fiber is introduced at the web formation stage to perform the binding function later in the process. Among several thermal-bonding systems, Condako is using the calendaring system, where heat and high pressure applied through rollers to weld the fiber webs together at speed.
- Mechanical Bonding (Needle Punch): refers to the strengthening of the web by inter-fiber friction as a result of the physical entanglement of the fibers. Among the two types of mechanical bonding, Needle punching system, use specially designed needles are pushed and pulled through the web to entangle the fibers.
- Spunbond: Spunbond fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. The fibers are separated during the web laying process by air jets or electrostatic charges. The collecting surface is usually perforated to prevent the air stream from deflecting and carrying the fibers in an uncontrolled manner. Bonding imparts strength and integrity to the web by applying heated rolls or hot needles to partially melt the polymer and fuse the fibers together. Since molecular orientation increases the melting point, fibers that are not highly drawn can be used as thermal binding fibers. Polyethylene or random ethylene-propylene copolymers are used as low melting bonding sites.
- Spunlace: This kind of Non Wovens are being produced with the use of the water jet technique. Textile - like drape, softness, durability, relatively high strength, good mechanical and esthetic, and good absorbency, these are only main spunlace features quite important, sometimes decisive for the final users.
- Polymers: PP, PET, recycled PET, Viscose-Rayon, PE, BICO and blends
