20 Claims

1. Reinforcing fibers, comprising:

hydrophilic fibers and

an adhesive component,

wherein:

surfaces of the hydrophilic fibers are at least partially covered with the adhesive component,

the adhesive component comprises a modified conjugated diene rubber having a hydrogen-bonding functional group in a part of the modified conjugated diene rubber, and an emulsifier,

the number of the hydrogen-bonding functional groups in the modified conjugated diene rubber is from 2 to 150 per molecule on average,

a melt viscosity measured at 38° C. of the modified conjugated diene rubber is from 0.1 to 4,000 Pa·s, and

the number-average molecular weight (Mn) of the modified conjugated diene rubber is at least 20,000.
