Stenter Frame Design and Hot Air Circulation
topic
Stenter frames use pin or clip chain transport to hold fabric at defined width through 4 to 12 drying chambers equipped with hot air impingement nozzles delivering 100 to 200 degrees Celsius air at velocities of 25 to 40 metres per second perpendicular to the fabric surface, with heat recovery systems recirculating exhaust air through heat exchangers to reduce the fresh air heating energy requirement by 30 to 50 percent.
Role
Provides the primary continuous drying and width-setting equipment for woven and knitted fabrics in finishing, combining the functions of drying, chemical finish curing, width dimensioning, and weft straightening in a single pass that represents the most critical single machine investment in a textile finishing facility for its central role in determining fabric dimensional quality and processing efficiency.
