Punched Felt
Needle punched felt refers to felt that
is made by vertically needling fibers together to achieve a desired
thickness and density. Needled felt is commonly made from wool,
synthetic and other re-processed fibers. When viewing a cross-section
of needled punched felt, the fibers lay vertically, as opposed to
pressed felt, where the fibers lay horizontally.
Needle punched wool felt normally contains a lower
percentage of wool as compared to SAE wool felts, and is therefore
less expensive. F-15N and F-26N are the two standard type of needle
punched wool felt. Sutherland Felt Co can also make needle punched
equivalents to SAE grade F-3 and F-7 pressed wool felts. These normally
have a lower wool content than their SAE grade counterparts, but
are made to comparable densities. These materials are often used
for packaging, crating, and lining applications, where a lower grade
felt is acceptable. Sutherland Felt Co. can custom manufacturer
various densities, thickness and blends to your specifications.
