To Compare the Water Absorption Capacity of Fibres

Materials Required

  • 2 × 2 cm piece of cotton
  • Wool  
  • Nylon 
  • Beaker
  • One beaker containing water
  • Funnel 
  • Tripod stand 
  • Forceps
  • Weighing Machine. 

 

The Procedure

Real Lab Procedure 

  • Take the cotton fabric (2 × 2 cm) and weigh it.  
  • Immerse the fabric in water filled in a beaker. 
  • Pour out the excess water by tilting the beaker. 
  • Place a funnel on a tripod stand and keep a beaker under the stem of the funnel. 
  • Take out the wet fabric from the beaker and put it in the funnel. 
  • Wait till water stops dripping out from the fabric. 
  • Now weigh the wet fabric and note your observation in the table. 
  • Repeat the same steps for the woollen and nylon fabrics. 

Simulator Procedure

  • Drag the forceps towards material to collect and drop it in the weighing machine.
  • Observe the dry weight of the material.
  • Drag and drop the forceps towards the weighing machine to collect the material.
  • Drag and drop the forceps with material towards the beaker containing water.
  • Drag the beaker containing material and water and drop it at the top of the funnel to pour out excess water.
  • Drag and drop the forceps towards the beaker to collect the material.
  • Drag the forceps with material and drop it on the funnel to pour out any residue water.  
  • Drag and drop the forceps on the funnel to collect the material.
  • Drag and drop the forceps with material towards the weighing machine.
  • Observe the wet weight of the material.
  • Observe the displayed data on the mass of material.
  • Select the correct answer for question displayed related to the material.
  • Click on the Next button.
  • Repeat the above steps for all materials.
  • After completing all the above procedures with the all given materials a tabular data is displayed comparing all the dry and wet weight of the materials and calculations.

Conclusion

Water absorption capacity of fibres is in the order: Cotton > Wool> Synthetic (Nylon).
