The utilization of kapok (Ceiba pentandra (L.) Gaertn.) as cotton substitute for medicinal use.

 Mariano TJ

Bibliographical research was undertaken regarding the studies on applied species and related fibers
The fibers on Philippine kapok were subjected to a process of purification, taking into account, temperature during purification, and length of duration of the process
Analysis of the chemical composition of kapok fibers was undertaken and found to contain 11.05% volatile ether extractive; 20.585% non-volatile ether extractive; 1.081% ash; crude fiber 5.8055%; lignin 22.52% and nitrogen free extract 39.9535%. Organic nitrogen was found to be absent
The best conditions essential to produce absorbent and distinguishable fibers are: use of 0.25% sodium hydroxide; employing a solution of sodium hypochlorite containing 0.105% hypochlorite and furnishing 0.8489% of available chlorine. Absorbency test proved that the texture of the fibers is such that its absorbent power is lower than that of cotton
The low percentage of cellulose and the weak texture of kapok fibers account for the small yield of cellulose tetranitrate, which makes the preparation of pyroxylin unprofitable.(Author)
