Biocompatible phosphate based continuous glass fiber and fabric prepared from same

Abstract

The invention discloses biocompatible phosphate based continuous glass fiber and a fabric prepared from the same. The biocompatible phosphate based continuous glass fiber comprises, by mole, 35-55 parts of P2O5, 10-40 parts of CaO, 10-30 parts of MgO, 2-20 parts of B2O3, 0-24 parts of Na2O, 0-5 parts of K2O, 1-10 parts of Fe2O3 and 0-15 parts of MxOy, wherein MxOy is Ag2O or CuO2 or Ga2O3. The biocompatible phosphate based continuous glass fiber has good fiber forming processing property, good fiber forming property, strong spinnability, good chemical stability, and controllable degradation speed and biological activity, and the mechanical property is matched with that of bone tissue; the mechanical performance of a material obtained by compounding a textile product processed from the fiber with PLA and other degradable high-molecular polymers reaches the level of human bones.

Description

technical field [0001] The application relates to a biocompatible phosphate-based continuous glass fiber and a fabric prepared therefrom, belonging to the field of biomedical materials. Background technique [0002] Bioactive glass (bioactive glass) is a kind of material that can repair, replace and regenerate body tissues, and can form a bond between tissues and materials. It is used for bone tissue engineering in bone repair or bone replacement. 40 years ago, American scientist LHench discovered that 45S5 bioactive glass has the characteristics of being able to combine with human bone tissue. The weight percentages of each oxide in the glass component are: SiO 2 : 45.0%; CaO: 24.5%; Na 2 O: 24.5%; P 2 o 5 : 6.0%. A series of improvements were subsequently made to this type of glass formulation for clinical applications such as artificial dentistry and orthopedic treatment. However, silicate bioactive glass takes a long time to degrade, which takes 1 to 2 years. SiO 2...
