PVA is used as a modifier for thermosetting resin,such as urea formaldehyde resin or melamine formaldehyde

resin,to make fabric resist to wrinkle and shrinkage.PVA is chemically bonded to the thermosetting resin,

reducing the brittleness of resin,and preventing any decrease in the tear resistance of the fabric.PVA is also

used alone to give the fabric hard finish without the irritating smell of formaldehyde.
