POLY(METH)ACRYLIC ACID-BASED POLYMER COMPOSITION

摘要

The present invention provides a polymer composition capable of providing fibers with an enough penetration speed and enough water retention, while maintaining a favorable hue of the fibers, when used as a fiber crosslinking agent. The present invention also provides a fiber crosslinking agent and crosslinked fibers using the polymer composition. The present invention further provides a polymer composition that enhances the absorption properties of fibers and is especially useful for applications which strongly require the absorption properties, and a fiber crosslinking agent and crosslinked fibers using the polymer composition. The present invention is a polymer composition containing a poly(meth)acrylic acid polymer; and a bisulfite (salt)-added (meth)acrylic acid (salt) or a hypophosphorous acid (salt).
