Spacer-tech synthetic fabric designed for making ordinary clothes. It is soft, light, strong, and insulates well.
Additionally, the starting gear on any New Arrivals scenario is a synthread T-shirt and pants, and occasionally a jacket as well. Some raiders and outlanders will occasionally come wearing synthread apparel, as well.
The difficulty in sourcing sufficient synthread for use is not rewarded by its stats. It is the 9th most protective of the 31 textiles in the game against sharp damage, and the tied for second worst against heat damage. only beating patchleather. It has middling cold and heat insulation and provides the same item health as most leathers. Thus, if it should be found in the early game it is a decent candidate for dusters and other protective clothing, but it should be replaced by the better leathers or even devilstrand by the mid-game.
For use in furniture, it has a middle-of-the-road beauty factor, but its rapid redundancy as clothing and the demand for more beautiful textiles like Thrumbofur in other roles makes it a decent choice for improving furniture beauty once the colony has transitioned to more protective textiles.
Its one advantage over other textiles is that it, and its products, are 30% less flammable than normal textiles, though still more flammable than Hyperweave or Devilstrand, which are both 60% less flammable than normal.
