Thermoplastic Powder Bonding Systems
topic
Thermoplastic powder bonding scatters low-melting polyamide, polyester, or polyethylene powder at 10 to 30 grams per square metre onto the fibre web through a scatter coater, melts the powder in an infrared or through-air oven to create adhesive bond points at fibre intersections, and smooths the surface under light calender pressure, producing nonwoven interlinings and composite bonding nonwovens without the VOC emissions of solvent-based binder systems.
Role
Provides a solvent-free chemical bonding alternative for interlinings and technical nonwovens that uses thermoplastic adhesive powder as the bonding agent, with powder scatter application enabling controlled binder distribution at defined add-on levels and particle size that can be reactivated by heat during garment fusing operations to provide the bonding adhesive for apparel interlining applications.
