Tufted Broadloom Carpet - Wacker Chemie AG


Tufted Broadloom Carpet

  • Secondary Backing

    Commonly made of woven polypropylene. Also used are felts or heavy weight backings. Main function: contributes to the dimensional stability of carpets.

  • Secondary Coating

    Formulated with VINNAPAS® VAE dispersions; filled with calcium carbonate (selected fillers)and adjusted with additives, e.g., dispersing agents or thickeners. Main function: delamination properties; fixation of secondary backing; contributes to the dimensional stability of carpets.

  • Precoat

    Formulated with VINNAPAS® VAE dispersions; filled with calcium carbonate (selected fillers) and adjusted with additives, e.g., dispersing agents or thickeners. Main function: tuft bind. The precoat fixes the fibers to the primary backing.

  • Primary Backing

    Can be made from woven or nonwoven fabrics. Main function: carrier for fibers.

  • Carpet Face

    Made from synthetic fibers, – such as polyamide, polypropylene and polyester, – or natural fibers, such as wool or sisal.

Tufted broadloom carpets normally consist of a multi-layered structure as shown in the drawing. Providing effective adhesion between the different layers is one of the challenges that must be met by VINNAPAS® VAE dispersions. When used in the primary coating (precoat), VINNAPAS® products provide the strength to lock the tufts of yarn in place (tuftbind). In the secondary coating, they ensure dimensional stability by bonding the secondary backing to the carpet. VINNAPAS® VAE dispersions can provide the desired level of stiffness or "hand". Moreover, they show reduced flammability.
