LOW TISSUE IRRITATION AND REACTION :
LOW CAPILLARITY : wicking phenomena
Good handling and knotting properties
Sterilization without deterioration.

PRINCIPLES OF SUTURING
The needle should be grasped at approx. one third
distance from the eye and two thirds from the point.
The needle should enter the tissues perpendicular to
The needle should be passed through the tissues
The suture should be passed at an equal depth and
from the incision on both sides.
The needle always passes from the thinner tissue to
The needle always passes from the deeper to the
The sutures should be tied only to approximate the
tissues , not
The knot should never lie on the incison line.

from the incision , so as to evert the wound
