Abstract
Methods for dyeing suture material that include incubating the suture material in a high temperature staining bath comprising hematein are disclosed. The staining bath may include a nonionic surfactant. The method is carried out in the absence of chromium salts. Also disclosed are (i) a dyed suture material produced by the methods and (ii) a surgical suturing kit that includes the dyed suture material.
Claims34
A method for dyeing suture material, the method comprising the steps of:
- a) mixing hematein and a nonionic surfactant to obtain a dye solution;
- b) placing a suture material in H2O in a vessel;
- c) heating the H2O in the vessel from 20° C. to 40° C.;
- d) adding the dye solution to the heated H2O in the vessel to form a staining bath;
- e) incubating the suture material in the staining bath at 40° C. to 135° C. for 120 min to 150 min, thereby obtaining dyed suture material,
- wherein the method is carried out in the absence of chromium salts.
