Spider's silk is made of Spider web, which is 5x stronger than steel. Superman is the "man of steel" meaning that Spiderman is at the least 5x stronger than Superman. Plus Spider silk is said to be a light weight material giving Spiderman a better lvl of agility than Superman.
- And Superman Pre-Crisis has been stuck in Spider web before and was helpless. So the same should happen here.
