URETHANE FOAM REINFORCING MATERIAL

摘要

[PROBLEMS] To provide a urethane foam reinforcing material, which can suppress abrasion sound generated with a metal spring, high productivity, excellent handleability, and can be applied to even a urethane foam mold having large unevenness. [MEANS FOR SOLVING PROBLEMS] A urethane foam reinforcing material is characterized in that a nonwoven cloth (A) having a single yarn fineness of 1.0-3.0dtex, and a nonwoven cloth (B) having a single yarn fineness of 0.5-2.5dtex are laminated by needle punch process at a needle density of 35-70 needles/cm², by permitting needles to enter from a direction of the nonvwoven cloth (A).
