    Abstract: A process for modifying a fibrous product containing cellulosic fibers which comprises treating said fibrous product with a solution or dispersion containing a particular acrylic copolymer having a glycidyl group and an alkylene oxide sidechain, drying the fibrous product; and heat-treating it in the presence of an acid catalyst at a temperature sufficient to cleave the oxirane linkage of the glycidyl group. This process can impart superior dry and wet crease resistances, shrinkage resistance and wash and wear properties and also soil removing ability, resistance to redeposition, water absorption and water penetrability to fibrous products containing cellulosic fibers while retaining their mechanical strength characterics.
