Liquid fabric conditioner composition and method of use
First Claim
1. Method of conditioning fabrics, comprising:
- (a) contacting cotton fabric with a liquid composition comprising consisting of an amino-functional silicone, an amidoamine quaternary ammonium, water, salt, viscosity controlling agent and fragrance; and
(b) drying said fabric so that the fabric temperature is 200 degrees F. or greater;
wherein the delta b* of cotton fabric is greater (more negative) than the delta b* of a control when subjected to at least 15 cycles, a cycle is comprised of a wash step followed by a conditioning step according to step (a) and drying step according to step (b) and the softness of the fabric does not decrease.

Abstract
The invention includes a method of conditioning fabrics, comprising contacting fabric with a liquid composition comprising an amino-functional silicone and a quaternary ammonium, and drying said fabric at 200 degrees F. or greater. The invention includes a method of conditioning fabrics, comprising washing fabric in a detergent having a wash pH of greater than 10, contacting fabric with a liquid composition comprising an amino-functional silicone and a quaternary ammonium, and drying said fabric at less than 200 degrees F. The invention further provides a method of conditioning fabrics wherein softness, anti-static, and anti-wrinkle properties are imparted to the fabric wherein the conditioned fabric resists yellowing in industrial and institutional conditions wherein the wash pH is greater than 9 and/or the fabric temperature is 200 degrees Fahrenheit or greater.

4. A method of treating fabric, the method comprising:
- (a) allowing cotton fabric to contact a liquid fabric conditioning composition, wherein said composition consists of;
(i) an amidoamine quaternary ammonium compound;
(ii) an amino-functional silicone compound;
(iii) water;
(iv) salt;
(v) viscosity controlling agent and (vi) fragrance; and
(b) subjecting said conditioned fabric to the inside of an industrial dryer during a drying operation wherein the fabric temperature is 200 degrees Fahrenheit or greater, and the delta b* of said fabric is greater (more negative) than the delta b* of a control after 15 cycles, wherein a cycle comprises a wash step, a treating step according to step (a), and a drying step according to step (b). - View Dependent Claims (5)
