Research topic for PhD (textile engineer, Technology Management)

I am textile engineer and just finished my MSc (Technology Management), now I am interesting to do PhD. I want to choose topic related to quality and production in textile industry, but this is a general topic and lot of research already done in this field. I want to do something like technology in textile and role of technology for improving quality and reducing production cost per product. I am really stuck and not have any idea about unique topic for PhD. Please suggest me any good idea or topic related to textile management. Thanks

This is not a problem. It's an opportunity! If you are interested in the use of technology to improve efficiency, you should read a few VERY recent articles about the newest technologies in use.

Those articles will include section near the beginning that REVIEW a lot of other articles. When you read the literature review, it will give you a "crash course" on all the recent developments.

Your job is to read about lots of recent developments and then see what PROBLEM can be solved to improve efficiency.

You have 2 tasks:

1.) Read all about quantitative and qualitative research designs so that you know what your options are.
2.) Read some literature reviews in recent articles about subjects that interest you.

When you have read about 8 different research designs and also 8 different recent articles, and if you take notes about all of them, you will be ready to plan a project!
