Abstract

Systems and methods useful for treating a fabric article with a composition comprising polyol-based fabric care materials and a dispersing medium. The dispersing medium is a liquid at room temperature and has a flash point of greater than about 65° C. Specifically, the composition may be dispensed to treat fabric articles in an appliance during the fabric article drying process.

Claims

1. A method for applying a fabric treatment composition to a fabric article in a fabric article drying appliance, said method comprising the steps of:

(a) providing a drying appliance comprising a treatment chamber and a fabric article treating device;

(b) providing a fabric treatment composition comprising a polyol-based fabric care material and a dispersing medium, wherein the polyol-based fabric care material has the following formula;

P(OH)<sub>w−

s</sub>(OC(O)R¹)_x(OR²)_yR³_z(LR⁴)_uX_v

wherein P(OH)_w is a polyol,

R¹, R², R³ and R⁴ are moieties independently selected from C1–

C22 alkyl or C1–

C30 alkoxy, linear or branched, cyclic or acyclic, saturated or unsaturated, substituted or unsubstituted;

L is a linkage, which is an atom selected from O;

S;

N;

P;

X is a heteroatom-containing functional group, wherein the heteroatom is independently selected from O, N, S, P, Si and F;

w is an integer selected from 2 to 20;

x, y, z, u and v are integers independently selected from 0 to w;

s is the sum of x+y+z+u+v and s≦

w;

(c) placing a fabric article in said treatment chamber;

(d) dispensing said composition into said treatment chamber such that said dispensed composition contacts said fabric article;

wherein the fabric treating device is removably attached to said drying appliance and is configured to dispense said composition into said chamber.

2. The method of claim 1 wherein said composition is dispensed in the form of droplets having an avenge particle size in the range of from about 0.1 to about 1000 microns.

3. The method of claim 1 wherein the dispersing medium is water or a water soluble solvent selected from the group consisting of C4 to C7 glycol ethers, C2 to C7 glycols, polyethers, and mixtures thereof.

4. The method of claim 1 wherein the dispersing medium is liquid at room temperature and has a flash point of greater than about 65°

C.

5. The method of claim 1 wherein said composition has a viscosity of about 1 to about 200 cps at room temperature.

6. A method of applying a fabric treatment composition to a fabric article, said method comprising the steps of:

(a) providing a source of a fabric treatment composition comprising a polyol-based fabric care material and a dispersing medium, wherein the polyol-based fabric care material has the following formula;

P(OH)<sub>w−

s</sub>(OC(O)R¹)_x(OR²)_yR³_z(LR⁴)_uX_v

wherein P(OH)_w is a polyol,

R¹, R², R³ and R⁴ are moieties independently selected from C1–

C22 alkyl or C1–

C30 alkoxy, linear or branched, cyclic or acyclic, saturated or unsaturated, substituted or unsubstituted;

L is a linkage, which is an atom selected from O;

S;

N;

P;

X is a heteroatom-containing functional group, wherein the heteroatom is independently selected from O, N, S, P, Si and F;

w is an integer selected from 2 to 20;

x, y, z, u and v are integers independently selected from 0 to w;

s is the sum of x+y+z+u+v and s≦

w;

(b) providing a drying appliance comprising a treatment chamber;

(c) providing a dispensing device, which is configured to be removably attached to said drying appliance and to be in fluid communication with said source;

(d) placing a fabric article in said treatment chamber,

(e) dispensing said composition into said treatment chamber such that said dispensed composition contacts said fabric article.

7. A method of applying a fabric treatment composition to a fabric article, said method comprising the steps of:

(a) providing a source of a fabric treatment composition comprising a polyol-based fabric care material and a dispersing medium, wherein the polyol-based fabric care material has the following formula;

P(OH)<sub>w−

s</sub>(OC(O)R¹)_x(OR²)_yR³_z(LR⁴)_uX_v

wherein P(OH)_w is a polyol,

R¹, R², R³ and R⁴ are moieties independently selected from C1–

C22 alkyl or C1–

C30 alkoxy, linear or branched, cyclic or acyclic, saturated or unsaturated, substituted or unsubstituted;

L is a linkage, which is an atom selected from O;

S;

N;

P;

X is a heteroatom-containing functional group, wherein the heteroatom is independently selected from O, N, S, P, Si and F;

w is an integer selected from 2 to 20;

x, y, z, u and v are integers independently selected from 0 to w;

s is the sum of x+y+z+u+v and s≦

w;

(b) providing a drying appliance comprising a treatment chamber;

(c) providing a dispensing device, which is included with said drying appliance and which is in fluid communication with said source;

(d) placing a fabric article in said treatment chamber;

dispensing said composition into said treatment chamber such that said dispensed composition contacts said fabric article.
