Answers
Answer:
Synthetic fibers such as polypropylene and polyester are commonly used in the construction of surgical drapes and gowns as well as viscose. Antimicrobial nonwoven fabrics were prepared by directly incorporation of a qurternary ammonim salt namely, cethyl trimethyl ammonium bromide, on polyester and polypropylene and viscose nonwoven fabrics. An interesting observation is the clear zone of inhibition and excellent reduction of bacteria growth on polyester and polypropylene fabrics. It is apparent that the antimicrobial activity of CTAB is bactericidal in nature and not bacteriostatic. CTAB was effective as antibacterial agent on E.coli for three different fabrics. However CTAB was not effective on S. aureus and P. seudomonas when applied to viscose fabrics which may suggest that nature of substrate influence on the antibacterial activity of CTAB.
The antimicrobial and fluorochemical finishes used in this study were miscible in a single bath and could be applied to nonwoven fabrics to impart the desirable properties.

Synthetic fibers are formed by extruding a fiber-forming substance, called spinning dope, through a hole or holes in a shower head-like device called a spinneret, shown in Figure 15.3; this process is called spinning. The spinning dope is created by rendering solid monomeric material into a liquid or semiliquid form with a solvent or heat.
