Abstract
A composition for treating fabric includes about 0.1 to about 10.0% cross linking agent, about 0.1 to about 5.0% polyolefin, about 0.1 to about 0.5% wetting agent, about 0.0 to about 8.0% aminofunctional silicone, about 0.0 to about 6.0% ionizing agent, about 0.0 to about 2.0% catalyst and any remainder as a carrier. The composition has a pH of between about 2.0 to about 4.0 and at least some aminofunctional silicone and/or ionizing agent is provided.
Claims12
A method of durably ionizing a fabric, the method comprising:
- treating the fabric with a composition consisting of
- about 5% to about 15.0%, by weight percent, maleic acid/acrylic acid copolymer, or salts thereof, having a molecular weight of at least about 20,000,
- a blocked copolymer of polyester/polyethylene glycol,
- about 0.01% to about 4.0%, by weight percent, anionic surfactant,
- about 0.01% to about 4.0%, by weight percent, nonionic surfactant and
- a carrier;
- and
- drying the treated fabric.
A method of durably ionizing a fabric, wherein durability is determined based on laundering according to AATCC Test Method 135, and wherein ionization is determined by a decreased time to dissipate one-half of a 100-volt charge using a Rothschild Static Voltmeter, the method comprising:
- treating the fabric with a composition consisting of
- about 5% to about 15.0%, by weight percent, maleic acid/acrylic acid copolymer, or salts thereof, having a molecular weight of at least about 20,000,
- a blocked copolymer of polyester/polyethylene glycol,
- about 0.01% to about 4.0%, by weight percent, anionic surfactant,
- about 0.01% to about 4.0%, by weight percent, nonionic surfactant and
- a carrier, wherein the composition has a pH in the range of about 2.0 to about 4.0;
- and
- drying the treated fabric.
