Looks like your UV unwrapping is wrong. What modelling program did you use?

If you are using alpha blending, then probably you are not writing to depth; And perhaps you are using a shader with disabled backface culling. That would lead to triangles overlapping each other.

If that's the case, then the best solution would be to enable backface culling. Also, yo use non-commutative blending with particle system might require the system to be sorted by distance, which is relatively expensive.
