There’s no resin, it’s just layers of fabric.

I think the same is true of Casimir Zeglen's bulletproof silk vest c. 1901–1914.

ETA:

A fabric produced there, which is one-eighth of an inch in thickness, four ply, presents this perfection of weave, and all efforts to penetrate it with bullets has proved futile. The Rev. Mr. Zeglen himself submitted to a test in Chicago. He put on a vest of the material and an expert revolver shot fired at the vest at eight paces and no one of the bullets at all disturbed Mr. Zeglen. The weight of the fabric is half a pound to the square foot. It is soft and flexible, so that all kinds of garments can be manufactured out of it. The most practical form of garment is a vest, which can be worn at all times as a protection to life. The second kind of fabric is a simple textile goods, being an inch thick and weighing two pounds to the square foot. This fabric resists and wards off all kinds of leaden bullets from military rifles at any distance, dum-dum bullets at a range of 400 yards and steel bullets at a distance of 800 yards. The third kind of fabric is also of silk, textile, one inch thick, covered on the outside with a steel armor one-sixteenth of an inch in thickness. The silk and steel together weigh four pounds to the square foot, and the armor wards off steel bullets from military rifles at a range of 250 yards. The same steel bullets can be warded off at a range of 200, 100 and 50 yards, but the steel armor must be increased to the thickness of one-tenth of an inch and at a range of 50 yards to one-eight of an inch.
