Spray Bonding Line

The spray bonding process is used for covering and bonding the surface of the web and for bonding of the complete web to increase the following properties

• prevention of bleaching out

• increasing the loft and the rebound force

• increasing the resistance against chemicals and ageing

• to guarantee the waterproof of the Nonwoven

Spray bonding is used for PES- Nonwoven mostly.

The binder dispersion is based on acryl and plastics.

In everyday life you meet this kind of treated Nonwoven in forms of

• fibrefill for dresses and pillows (interlinings)

• quilted cotton wad for thermo-dresses and comforters

• upholstery materials

• isolating materials

• scouring pads

• technical filtres

We differentiate between one-sided and both-sided spray bonding:

The one-sided spray bonding is a process of three steps:

• spraying by airless or compressed air atomizer

• drying by the RegulAir^® Drying Conveyor Oven

• polymerising by the RegulAir^® Drying Conveyor Oven

One-sided spray bonding

The both-sided spray bonding is a process of five steps:

• first side spraying by airless or compressed air atomizer

• drying by the RegulAir^® Drying Conveyor Oven

• opposite side spraying by airless or compressed air atomizer

• drying by the RegulAir^® Drying Conveyor Oven

• polymerising by the RegulAir^® Drying Conveyor Oven

Both-sided spray bonding
