For tearing the cable jacket.
The string provides no suplemental physical support to the cable for bending, stretching or anything else. (Mostly because the cable doesn't need it. The copper is much stronger than the nylon) Also, the string isn't (or damn well shouldn't be) crimped into the connectors.
Its SOLE purpose is to tear away long sections of cable jacket.

They are used to strip the outer insulation from the cable. If you use a knife on the insulation, you can cut the insulation in the wires inside. If you simply pull on the outer insulation to tear it off, you can put too much stress on the wires inside.
I generally cut the outer insulation about 1/4" or so, then find the polyester strand, ant pull it along where I made the cut to open the outer insulation as far as I need it.

When you strip back the outer jacket, you run the risk of nicking the wires. So to alleviate this problem, when you strip the outer jacket, you grab all of the wires with one hand and then you pull the string down the length of the jacket with the other hand essentially tearing the jacket off without nicking the wire.

I'm not positive but I believe the strands add strength to the cable to prevent stretching.

They give the cable its strength so it doesnt bend as easy over longer distances
