hello sir... how r u? remember me? i'm sazid from bangladesh... i wrote u a mail a month back :)

just a small thing that's nagging me about this post is.... as of my knowledge HWM rayon and polynosic are the two synonyms for modified rayons and Modal being their trade name. here u have mentioned them to be fibers with different DP. can u pls explain?

and just a small correction that i thought i should suggest u is about the title of the post... u have named it to be 'DP of some natural fibres' but u mentioned natural, regenerated and synthetic fibers in it.

p.s.: i'm very proud to be the first follower of your blog and inspired by you i've also started blogging. pls pay a visit at http://sazidrahman.blogspot.com and give your opinion.

Author please clarify my confusion. I have read the degree of polymerization of cotton to about 5000 in the book "Textile Science" by EPG Gohl and yet another site(http://www.barnhardtcotton.net/technology/cotton-properties/) gives a reading of 9000- 15,000 and you have mentioned 4000-10,000?
I am confused as to which is correct? Please help. Thanks

Hi Hamidulallah,

I am referring you to a link from Indian Institute of Technology Delhi, which also state the DP as 5000
