Abstract

A power transmission belt (20) comprising a body (11) comprising an elastomeric material and having tensile members (10) running in a longitudinal direction, the body having a pulley-engaging region (12) having a profile; the pulley-engaging region comprising a fibrous nonwoven fabric material (15); characterized in that the fibers of the nonwoven material comprise acrylic fibers. The acrylic fibers are preferably micro-fibers of less than about 1.5 dpf and having an average diameter of 13.5 microns or less and an average length of about 1 to about 10 mm. The nonwoven material may be commingled with the elastomeric material in the pulley engaging region. Up to about 75% by weight of the fibers of the nonwoven material may comprise non-acrylic fibers such as other synthetic fibers, naturalfibers, or cellulosic fibers.

Description

technical field

[0001] The present invention relates to a power transmission belt having an engineered surface, and more particularly to a power transmission belt having an engineered surface comprising a region having a nonwoven material comprising acrylic fibers. Background technique

[0002] It is known in the art to manufacture power transmission belts from elastomeric materials with embedded stretchable members. Belts can be described as ribbed, toothed V-belts or flat profiles. The belt runs in pulleys with matching profiles.

[0003] It is known to use various textile materials or fibers to cover the surface of the belt, including the back, sides, profile and / or wedge sides, to modify the abrasion resistance, friction properties, rupture resistance of the surface and / or the underlying elastomeric regions , stiffness and / or strength properties. Specific fabric properties and / or processes may be required to mold the profile. For example the fabric may be pre-formed ...
