No, but it can affect things slightly due to dielectric parameters

Techflex as a speaker cable covering is generally made of polyester, and is braided. As such, it is another layer of insulation that is close to the speaker wire insulation. The electric field of the speaker wires spreads out into the space around the wires, and first encounters the insulation (dielectric) covering the wires, then after the electric field has passed through the wire insulation, it then encounters the Techflex as a dielectric.

If you have high performance speaker cables, they are likely to have a high quality insulation, like polypropylene, or Teflon, or a foamed form of those grades of insulation.
With very high quality dielectric's like these, the Techflex could slightly degrade the sonic performance of the cable, IF you have a high resolution system.

In my own rather comprehensive studies of audio cables, Techflex covering over a speaker cable wad just barely audible to me and other trained listeners. Techflex over interconnects was generally more audible, as interconnects are much more sensitive to quality issues with dielectrics than speaker cables, being primarily signal voltage based.

If you need your cables to "look pretty" (there is that wife acceptance factor in play sometimes), then do what you must, but other wise, it is superfluous in terms of the sound and actual performance of the cable.
