can I have fabric copied or duplicated? this would be in large amounts
for a line of womens apparel

What kind of fabric?  How copied?  Is it the woven fabric that you
want to copy or  a woven design, or do you want to copy a printed
design?
There could be copyright or patent restrictions.  Printed designs
often have a copyright printed along the selvedge.

Fabrics can be copied or duplicated, according to requirement.
Copyright issues do exist, but can be sidelined by effectively
manipulating the design to one's own advantage.

Note: Many high-street chains are regulary accused of copying design's
from competitior's, very regularly in the UK.

Good pricing may also be achieved, based on the quantity and lead-time.

For best pricing, it is sometimes wise place orders in advance, at an
offshore location. Countries like Bangladesh, India, Indonesia and
Thailand can produce good quality fabrics and are major players in the
export-market.

For high-standard fabrics, it would be wise to contact 'Arvind mills' in India. 

For a brief quote and further detailed information, one can also
contact: Mr. M.Q. Zaman, Jamuna Knitting & Dyeing, Bangladesh

Hi Maggiedo,

We are a Knitted fabric and garment manufacturer from India. Please
let me have some details of the fabric you are talking about. Are you
referring to reproducing a specific fabric design ? Please revert.

I'd agree Prabhu... for this kind of copy, it is easy for both India
or my country China....
I just quit my job in apparel company but I know there're lot of
fabric mill here working on this.
