Stenter

Fluctuating temperatures inside the stenter cause a consistent variation of crystallinity in the fibre structure, which leads to different affinity for dyes.The moisture in the fibre produces soft hand, but variable moisture percentages in the different fabric sections create the above mentioned defect (variable crystallinity).Too low temperatures do not allow a good setting while too high temperatures and too long setting times cause yellowing (PA and elastic fibres), stiff hand (acrylics), and loss of elasticity

丨Stenter Machine丨

A machine or apparatus for stretching or stentering fabrics. The purpose of the stenter machine is to bring the length and width to pre determine dimensions and also for heat setting and it is used for applying finishing chemicals and also shade variation is adjusted. The main function of the stenter is to stretch the fabric widthwise and to recover the uniform width.

丨Functions of Stenter Machines丨

1. Heat setting is done by the stenter for lycra fabric, synthetic and blended fabric.
2. Width of the fabric is controlled by the stenter.
3. Finishing chemical apply on fabric by the stenter.
4. Loop of the knit fabric is controlled.
5. Moisture of the fabric is controlled by the stenter.
6. Spirility controlled by the stenter.
7. GSM of the fabric is controlled by stenter.
8. Fabric is dried by the stentering process.
9. Shrinkage property of the fabric is controlled.
10. Curing treatment for resin, water repellent fabric is done by the stenter.

丨Components of Stenter Machine丨

1. • Padder
   • Photoelectric Weft straightner
   • Burners
   • Heat recovery(Options)
   • Attraction rollers
   • Circulating fans
   • Exhaust fans
   • Winder
   • Clips
   • Pins
   • Cooling drums

丨Working Procedure of Stenter Machine丨

1. open-width fabric  entry→ spreading→infrared centering→padder→  weft straightener   →overfeed→uncurling→infrared detect→ pinning→stentering→air cooling→depinning→fabric exit→plaiting/winding

丨Advantages丨

1. • Highest drying performance and process control matching any type of fabric due to the technically mature and patented split-flow air circulation system
   • Very homogeneous air flow and temperature distribution due to alternately arranged thermo zones (every 1.5m).
   • Very low specific energy consumption
   • Extremely robust chains, chain rails, pin bar carriers and clips, needing only little maintenance
   • Exactly reproducible finishing results because of a complete automation and recipe administration in the line
   • Available types of heating: Gas direct, gas indirect, thermal oil, steam, electricity and combinations thereof
   • Optimum straightening results due to an integrated straightener with shortest possible fabric path to the pinning-on point, available as option
