US 5,532,023 A · Wrinkle reducing composition

Abstract

The present invention relates to a wrinkle reducing composition for use on fabrics, particularly clothing. The composition comprises a wrinkle reducing active, which is made up of an effective amount of silicone and an effective amount of film-forming polymer, and a liquid carrier. The composition is substantially free of starch, modified starch, and mixtures thereof, and results a Loss Modulus Difference of greater than about 3.3.times.10.sup.7 Pascal on fabric. The composition can be incorporated into a spray dispenser that can create an article of manufacture than can facilitate treatment of fabric with the wrinkle reducing composition. The wrinkle reducing actives in the composition can be determined through Dynamic Mechanical Analysis using a 100% cotton broadcloth swatch and a fixed volume of a sample of wrinkle reducing active.

Dependent claims

A process for determining acceptable commercial wrinkle reducing active mixtures, which comprises:

A. mounting a fabric swatch in a tangential fiber extensional geometry in a Dynamic Mechanical Analyzer;
B. applying to said swatch, a fixed volume of a wrinkle reducing active mixture in a liquid carrier;
C. at a time no greater than 2 minutes,
1. reading a sample height, instrumentally;
2. setting stress values;
3. allowing temperature to equilibrate;
4. running said Analyzer;
5. collecting data and calculating an average between wet and dry fabric ranges;
D. monitoring a change in the fabric's ability to dampen an applied stress over time as the fabric dries;
and
E. determining whether said wrinkle reducing active has a Loss Modulus Difference of from about 3.3.times.10.sup.7 Pascal to about 5.5.times.10.sup.7 Pascal by subtracting wet region ranges from dry region ranges.
