I'm wondering what the most space and mass efficient system is to construct woven products such as rope, textiles, or clothing on Mars. Current textile production strategies often rely on methods which are unfeasible on Mars, such as Wool or conventional Polyester (petroleum based) manufacturing. Sheep and other animals that produce fibers require a huge amount of space and food and aren't really practical when living space and transport costs are at a premium. Polyester suffers a similar problem; So far we haven't discovered any easy-to-reach oil deposits on Mars and as such, making plastics in-situ is difficult. 

Ideas:

* Conventional cotton growing in greenhouses
* Fibrous plants such as bamboo harvested for fiber
* Mars imports bulk plastic (perhaps also for 3d printing) and makes polyester
* Thread can be synthesized from the regolith?

Question:

* What is the most space and mass efficient system for producing fiber for woven products on Mars assuming the cost of shipping in new fiber products outweighs the cost of producing them on Mars?
