Is Paper Made From Hardwood Or Softwood

The density of wood has the close connection with paper pulp quality for example paper yield per unit volume is proportional to density and high density wood pulp has slower beating rate bigger bulk and tensile strength.

Is paper made from hardwood or softwood.

Hardwoods have a higher density than most of the softwoods. Other than this a combination of hardwood and softwood trees is used in making them. This happens to be generally true but there are exceptions such as in the cases of wood from yew trees a softwood that is relatively hard and wood from balsa trees a. Classifying wood as either a hardwood or softwood comes down to its physical structure and makeup and so it is overly simple to think of hardwoods as being hard and durable compared to soft and workable softwoods.

Softwood trees such as southern pines and douglas firs have long fibers that wrap around each other. Paper made from softwood contains longer fibers. Lignin content of hardwood is less than softwood about 20 40 so hardwood is easier to make pulp and bleached less alkaline consumption required. In building components like windows doors furniture medium density fiberboard paper softwoods are used.

Softwood is the wood of coniferous trees such as pine and spruce where as hardwood comes from decidious trees such as oaks and maples. Softwoods have a lower density than most of the hardwoods. They simply would not have enough resistance to tearing.
