Question

Rayon and cotton swabs are both composed of cellulose. Rayon fibers have shorter cellulose chains. Which is more polar? Since the molecules in cotton consist of longer cellulose chains than those in rayon cellulose, the longer cotton molecules are also packed more in-line (crystalline areas) with each other than rayon’s more random (amorphous areas) molecules

Answer 1

cotton is more polar than rayon in latest studies.

Cotton is a natural fiber whereas rayon is semi-synthetic fiber. Both are made up of cellulose but we know that rayon is semi-synthesis fiber so in rayon we use purified cellulose whereas cotton is a naturally occurring fiber so we can't control it. Cotton is also stronger than rayon and also in water, cotton becomes stronger than rayon.

as it is seen that fibers which are on the softer side are less polar than other and due to which they absorb less water.In fiber, it is seen that they can become temporarily imbalanced. For a brief moment of time one part of a molecule would be negative, another part positive; it is temporarily polar. These occasional imbalances are enough to allow nonpolar molecules to attract each other, but the interaction is much weaker than that observed for polar or hydrogen bonding polymers.
