What are the chemical properties of cotton?

Chemical Properties of Cotton

  • Effects of Acids: Cotton is attacked by hot dilute acids or cold concentrated acids which it disintegrates.
  • Effects of Alkalis: Cotton has an excellent resistance to alkali.
  • Effects of Organic Solvents: Cotton has high resistance to normal cleaning solvents.

Why cotton is called natural?

Cotton is made primarily of cellulose, the polymer that is the building block for the cell walls in all plants. Cotton is classified as a natural cellulosic fiber and shares characteristics with other plant-derived fibers like linen, ramie and jute, in contrast to the man-made cellulosics such as rayon and acetate.

How do you determine the pH of fabric?

Take a swatch of 10 inches square of the fabric and put it in the boiling water for20 minutes. Remove the swatch and let the boiled water cool to room temperature. Measure the pH of the water with pH paper and record it. That pH should stay 7; and any change is on account of the fabric.

How do alkalis affect cotton?

Effects of Alkalis: Cotton has an excellent resistance to alkalis. It swells in caustic alkalis ( NaOH) but it does not damaged. It can be washed repeatedly in soap solution without any problem. Effect of Organic Solvent: Cotton has high resistance to normal cleaning solvents.

How do you test the pH of fabric?
