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).
