They use a rip-stop nylon, but even the best nylon can still tear

A parachute is usually a soft fabric device used to slow the motion of an object through an atmosphere by creating drag. Parachutes are normally used to slow the descent of a person or object to Earth or another celestial body within an atmosphere. Drogue parachutes are also sometimes used to aid horizontal deceleration of a vehicle (a fixed-wing aircraft or space shuttle after touchdown, or a drag racer). The word parachute comes from the French words para, protect or shield, and chute, the fall. Therefore parachute actually means "fall protection". Many modern parachutes are classified as semi-rigid wings, are quite maneuverable, and can facilitate a controlled descent similar to that of a glider.
Parachutes were once made from silk but now they are almost always constructed from more durable woven nylon fabric, sometimes coated with silicone to improve performance and consistency over time. Originally silk was used for parachute suspension lines, but was replaced by nylon during World War II. When square (also called ram-air) parachutes were introduced, manufacturers switched to low-stretch materials like Dacron or zero-stretch materials like Spectra, Kevlar, Vectran and high-modulus aramids. Kevlar is rarely seen except on reserve canopies.
A parachute is made from thin, lightweight fabric, support tapes and suspension lines. The lines are usually gathered through cloth loops or metal connector links at the ends of several strong straps called risers. The risers in turn are attached to the harness containing the load.
A parachute is carefully folded, or "packed" to ensure that it will open reliably. In the U.S. and many developed countries, emergency and reserve parachutes are packed by "riggers" who must be trained and certified according to legal standards. Sport skydivers are always trained to pack their own primary "main" parachutes.

Parachutes can malfunction in several ways. Malfunctions can range from minor problems that can be corrected in-flight and still be landed to catastrophic malfunctions that require the main parachute to be cut away using a modern 3-ring release system and the reserve be deployed. Most skydivers are also equipped with small barometric computers (known as an AAD or Automatic Activation Device like Cypres, FXC or Vigil) that will automatically activate the reserve parachute if the skydiver himself has not deployed a parachute to reduce his rate of descent by a preset altitude.

mostly nylon these days. it's very tough, not prone to rip, since ripping could prove problematic in a parachute. originally silk was used. silk however is expensive, and although quite strong is not rip-proof. also heavier than nylon.
