Spiders make an egg case, lay their eggs in it, and seal it up. Then they either carry the egg case along with them (as do the wolf spiderss, the fishing spiders, etc.), build a nursery web in preparation for holding in the baby spiders for a few days while they grow up a little and then hang the egg sac in there so they can hang out on the outside and protect everything (those spiders are called nursery web spiders), or they fasten the egg sac wherever they take shelter on a regular basis.
Spiders spin webs with their silk and also use it to wrap up their prey.

Use better grammar then maybe I can help you.
Spiders secrete a combination of proteins that they use to weave their webs. Some of the proteins create the silk and another protein makes up the sticky substance that traps the prey in the web.
