Fiber Chemical Test | Identification of Textile Fibers|

Identification of textile fiber through chemical solubility test.

Introduction:

Solubility is a chemical property referring to the ability of a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent. Fiber can be identified by physical test, chemical test, burning test, density test and many more test, but the chemical solubility tests properly understands which fiber mixed on fabric.

Fiber Chemical Test | Identification of Textile Fibers|

Objective

To identify of textile fiber through chemical solubility test.

Instrument

• Beakers
• Gloves
• Pipette
• Water
• 75% H₂SO₄

Methodology:

First of all, measure the weight of fabric sample in electronic precision GSM balance. Then keep 75% H₂SO₄ solution in a beaker by Pipette and put that fabric sample in the beaker. After few minutes keep that sample and wash out by water, then put that fabric in oven dryer for dry. Again, we measure that sample and noted down. There we see cotton fiber loop formation burned and polyester fiber loop still on the fabric. After calculate we understand that fabric was PC fabric.

Conclusion:

By this experiment we know which fabric is CVC & PC fabric. The previous experiment was a burning test of textile fiber this experiment is a chemical solubility test. From the solubility test, we can easily understand with fiber in fabric.
