Abstract
A textile treatment process, treatment bath, and treated fabric are disclosed. The process imparts water repellant, stain resistant, and wrinkle-free properties as well as aesthetically pleasing hand properties to a fabric made in whole or in part of fibers having a hydroxyl group, such as cellulosic fibers, though immersion in an aqueous bath and subsequent heating for curing. The aqueous treatment bath contains a urea resin, polytetrafluorethylene (PTFE) and, preferably, fluoroalkyl acrylate copolymer.
Claims20
An aqueous textile treatment bath for imparting water resistant, stain resistant and wrinkle-free properties to a fabric which has fibers having a hydroxyl group, such as cellulosic fibers, the aqueous bath formulated to apply to the fabric:
- 8% to 14% by weight of the fabric of a reactive modified ethylene urea resin solution;
- and
- 4% to 10% by weight of the fabric of a polytetrafluorethylene additive which is at least 25% by weight of a crosslinking polytetrafluorethylene (PTFE), whereby upon immersion of the fabric and subsequent heating, the urea resin reacts with the hydroxyl group and forms crosslinks with the polytetrafluorethylene to impart the properties to said fabric.
An aqueous textile treatment bath for imparting water resistant, stain resistant and wrinkle-free properties to a fabric which has fibers having a hydroxyl group, such as cellulosic fibers, the aqueous bath formulated to apply to the fabric:
- 0.6% to 3.3% by weight of the fabric of a reactive modified ethylene urea resin;
- and
- at least 0.2% by weight of the fabric of a crosslinking polytetrafluorethylene (PTFE), whereby upon immersion of the fabric and subsequent heating the urea resin reacts with the hydroxyl group and forms crosslinks with the polytetrafluorethylene to impart the properties to said fabric.
