We offer the following web consolidation methods: • Calender or Thermal Bonding: The web is bonded by using a calender to apply heat and pressure. Area and point bonding are the two primary methods used. Area bonding involves two smooth calenders through which the web is passed. Point bonding involves one patterned and one smooth calender, resulting in a loftier and textured web. • Chemical or Latex Bonding: Chemical bonding ties down the fibers used in making a web. Various properties can be imparted to the web when using latex binders to consolidate the web. For example, you might like your material to be heat sealable, flame retardant, pill-resistant, tear-resistant, or colored. • Thru-air Bonding: By exposing the web surface to hot air while moving through an oven, we can produce a very lofty and flexible material. • Needlepunching: Using barbed needles to mechanically entangle the web, we produce a very strong, yet lofty nonwoven. H&V produces filtration and industrial products with these processes ranging in weight from 15 to 500 g/m2 and incorporate polyester, rayon, bicomponent, and polyethylene staple fibers. © 2021 Hollingsworth & Vose Company Privacy Policy Products Industries UK Pension Sitemap Headquarters 112 Washington Street East Walpole, MA 02032 USA Map Americas +1.508.850.2000 Asia Pacific +86.512.6767.8600 Europe/Middle East/Africa +49.6101.98167.0 India +91.821.664.7711 Latin America +1.508.850.2102 Keep up with the latest H&V news Follow Us Hollingsworth & Vose Company, 112 Washington Street East Walpole, MA 02032 USA, is responsible for this website.
