ABSTRACT:
A method for treating fibers to obtain treated fibers suitable as a reinforcing material which comprises treating a fiber obtained from a polyester which shows anisotropy in the molten state in an aqueous solution of at least one compound selected from the group consisting of hydroxides, carbonates, bicarbonates, and organic carboxylic acid salts of lithium, sodium, potassium, magnesium and calcium at 20.degree. to 120.degree. C. for at least one minute.
The above-mentioned treatment provides treated fibers suitable as a reinforcing material which exhibit an excellent adhesion to matrices to be reinforced and can give a satisfactory strength to the resulting composite material.
