Claims13
A porous textile product made from bioactive glass fibers, characterized in that the fibers therein are of at least two types, fiber A and fiber B,
- fiber A being made of a bioactive glass, and
- fiber B being made of a weakly bioactive glass.
A textile product according to any of the above claims, characterized in that fiber A is made of a bioactive glass having the composition Na2O 6% by weight, K2O 12% by weight, MgO 5% by weight, CaO 20% by weight, P2O5 4% by weight, and SiO2 53% by weight.
A textile product according to any of the above claims, characterized in that fiber B is made of a weakly bioactive glass having the composition Na2O 6% by weight, K2O 12% by weight, MgO 5% by weight, CaO 15% by weight, P205 4% by weight, and SiO2 58% by weight.
A textile product according to any of the above claims, characterized in that the length of the fibers therein varies and that the order of the fibers in the product is not predetermined.
A textile product according to any of the above claims, characterized in that the textile product is a felt, fabric or mat.
A textile product according to claim 11, characterized in that it is made by the nonwoven technique.
A textile product according to any of the above claims, characterized in that the product may be impregnated with a substance which causes the product to harden after the product has been molded into the desired shape.
The use of a textile product according to any of the above claims as an implant, a product which yields a drug or another substance at a controlled rate, for the control of tissues, as a filler in bone cavities or soft tissue, in the removal of pulpa, as a dental root filler material, or as a binding agent for bone transplants.
