Finite Fiber specializes in precision cut fiber polymer reinforcing materials.

Cotton Fibers

Spun, treated denim cotton textile fibers are precision cut as an economical reinforcement additive for polymer products.
Sustainable, economical cotton fibers are physically superior to filler and warp thread blends in cotton reinforcement applications.


Spun and treated denim cotton textile fibers are produced from high quality warp thread materials. These spun materials offer the highest physical properties in the construction of textile fabrics and are physically superior to fill and warp thread blends in cotton reinforcement applications. Cotton is a natural cellulose polymer.


Cotton is characterized by its dimensional and thermal stability, resilience, inherent tensile strength, and toughness. Like many fiber types, uses are substantial in consumer, technical and industrial markets. Cotton also improves dimensional stability, cut and tear resistance, green strength, creep resistance and cut propagation when used in a elastomer matrix.
