All man made fibers are composed
of long chain molecules known as polymer which are formed by chemical
processing. The polymer manufacturing process is the determining factor for
many basic characteristics such as density, melting point, dyeing behavior,
moisture absorption etc.
Common groups in polymer:
- Amid or peptide groups.
- Benzin ring.
- Ether linkage (-C-O-C).
- Ester linkage (-C-O-O).
- Hydroxyl group (-OH).
- Nitrile group (-C-N).
There's no doubt i would fully rate it after i read what is the idea about this article. You did a nice job..
