Developmental Trends of Black Spruce Fibre Attributes in Maturing Plantations

Table 1

Product-based performance measures and their relationship with fibre attributes (sensu [5]).

Product category	Performance measure	Functional relationship with fibre attribute
Pulp and paper	Tensile strength	fibre length, (wall thickness)^−1
	Tear strength	fibre length, coarseness
	Stretch	microfibril angle
	Bulk	wall thickness, (fibre width)^−1
	Light scattering	(wall thickness)^−1
	Sheet formation	(fibre length)^−1
	Collapsibility	wall thickness
	Yield	density
Solid wood and composites	Strength	density, (microfibril angle)^−1
	Stiffness	density, modulus of elasticity, (microfibril angle)^−1
