Which of the following can absorb over of its own mass of water and also does no
Which of the following can absorb over \( 90 \% \) of its own mass of water and also does not stick to wounds?
- A. Saran
- B. Thiokol
- C. Rayon
- D. Gun cotton
Step-by-step solution
Rayon is a regenerated cellulose fiber that is highly hydrophilic, capable of absorbing over 90% of its own mass in water. It is commonly used in non-stick wound dressings because it does not readily adhere to moist wounds, unlike other materials such as Saran (plastic), Thiokol (rubber), or Gun cotton (nitrocellulose, which is hydrophobic and historically used as a film-forming collodion rather than an absorbent).
