Textile Stenter Machine | Functions Of Stenter Machine

Stenter is used for open form fabric. After passing the open compactor, fabric enter into the stenter. Cotton fabric shrinks widthwise and weft distorted due to bleaching and dyeing process. The main function of the stenter is to stretch the fabric widthwise and to recover the uniform width.

Functions of Stenter:

  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.

Stenter Machine: I present a stenter machine profile for your consideration. Following points are needed to consider during buy a stenter.

Textile Compactor | Functions And Checking Parameter Of Tubular And Open Compactor

Compactor machines are two types. They are-

  1. Tubular compactor
  2. Open compactor

Tubular compactor is used after hydro-extractor, de-watering and dryer. By the compactor machine, compacting is done for control the shrinkage of the fabric. Here, different types of off line quality of the fabric are measured.

Open compactor is used for compacting the open form fabric. Here, slitting machine is used for open the fabric from the tubular form.

Functions of tubular compactor: Following objectives are achieved by the tubular compactor. They are-

  1. Shrinkage of the fabric is controlled by the compactor.
  2. Fabric width is controlled by the compactor.
  3. GSM of the fabric is adjusted by the compacting.
  4. Fabric smoothness is achieved by the compactor.
  5. Heat setting of fabric for Lycra is done by tubular compactor.

Checking Parameters: Following parameters check in compactor machine.

  1. Shade Check: Shade of the compacting fabric is checked in the delivery side of the machine. The operator collects the fabric and compare the shade of the fabric with the buyer’s approved swatch.
  2. Width Check: Operator measures the width of the fabric with the measuring tape and compares it with the buyer’s requirement.
  3. Weight Check: Weight of the fabric is determined by GSM check. Operator checks the GSM of the fabric by GSM cutter and electric balance.
  4. Edge Line Checking: Two edges of the fabric is check in delivery side. If any fix line is identified, which normally occurs from the expander it should be connected.
  5. Design and Slanting: Operator checks design and slanting of the fabric in the delivery side of the machine.
  6. Fabric Faults: Various types of fabric quality are measured in the delivery side of the fabric.

Compactor Machine: Here, I have present tubular and open compactor with its specification. The figure which is mentioned here it is changeable depending on the demand.

Brand name Ferraro
Model no. Comptex/Fv200
Manufacturing country Italy
Speed range 16-35 m/min
Temperature 110-145C
Used utilities Electricity, Compress air, Steam
Production capacity 8 ton/day
Maximum width 52”
Minimum width 16”
Applied for Tube width

Another, Open Compactor:

Brand name Ferraro
Model no. Comptex/Fv200
Manufacturing country Italy
Speed range 13-22 m/min
Temperature 110-140C
Used utilities Electricity,Compress air,Steam

Minimum width 36”
Applied for Open width

So, we should be careful about the fabric faults. If any faults found in the fabric then we should adjust the machine parameter as per requirement.

Textile Dryer | Drying Machine Parameter Set Up For Relax Dryer

In textile finishing unit; dryer uses for dry the knit, woven fabrics and dyed yarn. But the drying process and drying mechanism of yarn and fabrics is different from one to another. In dryer, drying and curing is done as per required.

Drying: The main functions of a textile dryer is to dry the textile fabrics. Drying is defined as a process where the liquid portion of the solution is evaporated from the fabric.

Curing: Curing can be defined as a process following addition of a finish to the textile fabrics, in which materials are heated for a certain time in elevated temperature to effect a chemical reaction. This curing operation is most common in finishing of the printed goods.

Considering points for selecting relax dryer: Following points should consider during buy a dryer.

  1. Heating methods: The textile fabrics may be heated by gas burner or steam.
  2. Chamber: Number of chamber.
  3. Burner: Number of burner.

Drying Machine Parameter Set Up For Relax Dryer: Here I have given two relax dryer machine parameter.

Ruckh Relax Dryer (Germany):
