Definitions
- the present invention relates to a method for providing fast dry property to fabric.
- Drying can be done by line drying or dryer drying. In a dryer, the longer the drying time, the more energy that is used to dry the fabric. It would be desirable to reduce the time needed to dry fabric.
- WO01/27232A1 discloses a fabric care composition
- a fabric care composition comprising a polymeric material that is capable of self cross-linking and/or of reacting with cellulose together with one or more textile compatible carriers, wherein the polymeric material comprises one or more poly(oxyalkylene) groups having an end group which comprises one or more amino groups or derivatives of said amino groups.
- the compositions may be used to treat fabric as part of a laundering process and improve the surface color definition of the fabric following multiple washings.
- US2003/0162689A1 discloses a liquid fabric conditioner for fabric care and to the use of the conditioner in a washing or laundry drying process, to a conditioning substrate containing a liquid fabric conditioner, and to a conditioning process using the conditioning substrate in a laundry drying process.
- the liquid fabric conditioner and conditioning substrate are used to reduce fluff formation and pilling.
- US2007/0021315A1 discloses that hard water is softened by a composition comprising a fatty acid and/or an alkali salt thereof, a dispersing agent and a precipitation softener thereby simultaneously forming and dispersing an insoluble calcium salt of the fatty acid.
- GB2378960A discloses a fabric care composition
- a fabric care composition comprises a fluorocarbon stain-blocking agent and a cationic cross-linking polymeric material which is capable of self cross-linking and/or of reacting with cellulose together with one or more textile compatible carriers, wherein the cationic cross-linking polymeric material comprises one or more poly(oxyalkylene) groups having an end group which comprises one or more amino groups or derivatives of said amino groups.
- Use of the composition improves the surface color definition and stain repellency of a fabric after multiple washings and imparts pill and/or fuzz resistance.
- EP372848A2 discloses an aqueous emulsion of a perfluoropolyether having a molecular weight in the range 3000 to 8000 is made by agitating the perfloropolyether with a non-ionic non-fluorine-containing surfactant having an HLB value in the range 11.5 to 17.
- the emulsions may be used in fabric conditioners.
- a method according to claim 1 for reducing time needed for drying fabric comprising laundering the fabric at least 3 times with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with -N-(-CH 2 -CH(OH)-CH 2 -Cl) 2 , wherein the linear polyether is deposited on the fabric and reduces the time needed for drying.
- Preferred features are defined in the dependent claims.
- the molecular weight is less than 2000.
- a method for reducing time needed for drying fabric comprising laundering the fabric at least 3 times with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with -N-(-CH 2 -CH(OH)-CH 2 -Cl) 2 , wherein the linear polyether is deposited on the fabric and reduces the time needed for drying.
- the laundering can start with machine washing or hand washing. Washing typically includes using a detergent in a wash cycle. Washing is usually followed by a rinse cycle. After washing and rinsing, fabrics can be dried by hanging on a line or in a dryer. The fabric can be ironed after drying.
- the method can be used on any type of fabric.
- the fabric is in need of a reduced time for drying.
- Typical fabrics include any fabric used to make clothing, such as cotton, polyester, elastane, or denim.
- the fabric is denim.
- the composition used in the method can be used during any step of the laundering method. In one embodiment, the composition is added during the wash cycle. In one embodiment, the composition is added during the rinse cycle. It has been found that multiple launderings can increase the reduction of the time needed for drying.
- the fabric can be laundered with the composition for at least 3 times, at least 4 times, or at least 5 times.
- the composition contains a linear polyether having a weight average molecular weight less than 5000 that is terminated with -N-(-CH 2 -CH(OH)-CH 2 -Cl) 2 .
- the molecular weight is less than 4000, less than 3000, or less than 2000.
- the polymer has a molecular weight less than 2000.
- This polymer having a molecular weight less than 2000 is available from Devan Chemical under the PasserelleTM trademark as DP5270 or DFD.
- DP5270 is sold as an aqueous composition that contains 20% polymer with a total solids of 23-24%, with the other solids being surfactants.
- the DFD product contains 82% of the DP5270 product and further contains ethoxylated fatty-quaternary softeners.
- the amount of the polymer in the composition is 0.08 to 0.4% by weight of the composition. In certain embodiments, the amount is 0.1, 0.2, 0.3, or 0.4 % by weight of the composition.
- the DP5270 composition can be used in an amount of 0.5 to 1.5 % by weight of the composition, optionally at 0.5, 1, or 1.5 % by weight.
- the DFD composition can be used in an amount of 0.5 to 2 % by weight of the composition, optionally at 0.5, 1, 1.5, or 2 % by weight.
- the PasserelleTM polyethers are used to treat fabrics during the manufacture of the fabrics by direct application of the polyethers to the fabric to provide fast dry to the fabrics.
- the method of the invention allows the polyether to be added to fabrics that were never treated or to reapply the polyethers during home use.
- the polyether is included in a fabric conditioner.
- a fabric conditioner composition contains a fabric softener material.
- the softener is a cationic softener selected from among esterquats, imidazolinium quats, difatty diamide ammonium methyl sulfate, ditallow dimethyl ammonium chloride, and mixtures thereof.
- the cationic fabric softener is an esterquat.
- the esterquat is produced by reacting about 1.65 (1.5 to 1.75) moles of fatty acid methyl ester with one mole of alkanol amine followed by quaternization with dimethyl sulfate (further details on this preparation method are disclosed in US-A-3,915,867 ). Using this ratio controls the amount of each of monoesterquat, diesterquat, and triesterquat in the composition.
- the alkanol amine comprises triethanolamine.
- Monoesterquat is more soluble in water than triesterquat. Depending on the AI, more or less monoesterquat is desired. At higher AI levels (usually at least 7%), more monoesterquat as compared to triesterquat is desired so that the esterquat is more soluble in the water so that the esterquat can be delivered to fabric during use. At lower AI levels (usually up to 3%), less monoesterquat is desired because during use, it is desired for the esterquat to leave solution and deposit on fabric to effect fabric softening. Depending on the AI, the amount of monoesterquat and triesterquat are adjusted to balance solubility and delivery of the esterquat.
- the reaction products are 50-65 weight% diesterquat, 20-40 weight% monoester, and 25 weight% or less triester, which are shown below:
- the amount of diesterquat is 52-60, 53-58, or 53-55 weight %.
- the amount of monoesterquat is 30-40 or 35-40 weight%.
- the amount of triesterquat is 1-12 or 8-11 weight %.
- the percentages, by weight, of mono, di, and tri esterquats, as described above are determined by the quantitative analytical method described in the publication " Characterisation of quaternized triethanolamine esters (esterquats) by HPLC, HRCGC and NMR" A.J. Wilkes, C. Jacobs, G. Walraven and J.M. Talbot - Colgate Palmolive R&D Inc. - 4th world Surfactants Congress, Barcelone, 3-7 VI 1996, page 382 .
- the percentages, by weight, of the mono, di and tri esterquats measured on dried samples are normalized on the basis of 100%.
- the normalization is required due to the presence of 10% to 15%, by weight, of non-quaternized species, such as ester amines and free fatty acids. Accordingly, the normalized weight percentages refer to the pure esterquat component of the raw material. In other words, for the weight % of each of monoesterquat, diesterquat, and triesterquat, the weight % is based on the total amount of monoesterquat, diesterquat, and triesterquat in the composition.
- the percentage of saturated fatty acids based on the total weight of fatty acids is 45 to 75%. Esterquat compositions using this percentage of saturated fatty acids do not suffer from the processing drawbacks of 100% saturated materials. When used in fabric softening, the compositions provide good consumer perceived fabric softness while retaining good fragrance delivery.
- the amount is at least 50, 55, 60, 65 or 70 up to 75%. In other embodiments, the amount is no more than 70, 65, 60, 55, or 50 down to 45%. In other embodiments, the amount is 50 to 70%, 55 to 65%, or 57.5 to 67.5%. In one embodiment, the percentage of the fatty acid chains that are saturated is about 62.5% by weight of the fatty acid. In this embodiment, this can be obtained from a 50:50 ratio of hard:soft fatty acid.
- a ratio of hard fatty acid to soft fatty acid is 70:30 to 40:60. In other embodiments, the ratio is 60:40 to 40:60 or 55:45 to 45:55.
- the ratio is about 50:50. Because in these specific embodiments, each of the hard fatty acid and soft fatty acid cover ranges for different levels of saturation (hydrogenation), the actual percentage of fatty acids that are fully saturated can vary. In certain embodiments, soft tallow contains approximately 47% saturated chains by weight.
- the percentage of saturated fatty acids can be achieved by using a mixture of fatty acids to make the esterquat, or the percentage can be achieved by blending esterquats with different amounts of saturated fatty acids.
- the fatty acids can be any fatty acid that is used for manufacturing esterquats for fabric softening.

- Provided is a method for reducing time needed for drying fabric comprising laundering the fabric at least 3 times with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with -N-(-CH2-CH(OH)-CH2-Cl)2, wherein the linear polyether is deposited on the fabric and reduces the time needed for drying.
- The laundering can start with machine washing or hand washing. Washing typically includes using a detergent in a wash cycle. Washing is usually followed by a rinse cycle. After washing and rinsing, fabrics can be dried by hanging on a line or in a dryer. The fabric can be ironed after drying.
- The method can be used on any type of fabric. In certain embodiments, the fabric is in need of a reduced time for drying. Typical fabrics include any fabric used to make clothing, such as cotton, polyester, elastane, or denim. In certain embodiments, the fabric is denim.
- The composition used in the method can be used during any step of the laundering method. In one embodiment, the composition is added during the wash cycle. In one embodiment, the composition is added during the rinse cycle. It has been found that multiple launderings can increase the reduction of the time needed for drying. The fabric can be laundered with the composition for at least 3 times, at least 4 times, or at least 5 times.
- The composition contains a linear polyether having a weight average molecular weight less than 5000 that is terminated with -N-(-CH2-CH(OH)-CH2-Cl)2. In other embodiments, the molecular weight is less than 4000, less than 3000, or less than 2000. In certain embodiments, the polymer has a molecular weight less than 2000. This polymer having a molecular weight less than 2000 is available from Devan Chemical under the Passerelle™ trademark as DP5270 or DFD. DP5270 is sold as an aqueous composition that contains 20% polymer with a total solids of 23-24%, with the other solids being surfactants. The DFD product contains 82% of the DP5270 product and further contains ethoxylated fatty-quaternary softeners. The amount of the polymer in the composition is 0.08 to 0.4% by weight of the composition. In certain embodiments, the amount is 0.1, 0.2, 0.3, or 0.4 % by weight of the composition. Based on as supplied weight, the DP5270 composition can be used in an amount of 0.5 to 1.5 % by weight of the composition, optionally at 0.5, 1, or 1.5 % by weight. The DFD composition can be used in an amount of 0.5 to 2 % by weight of the composition, optionally at 0.5, 1, 1.5, or 2 % by weight.
- The Passerelle™ polyethers are used to treat fabrics during the manufacture of the fabrics by direct application of the polyethers to the fabric to provide fast dry to the fabrics. The method of the invention allows the polyether to be added to fabrics that were never treated or to reapply the polyethers during home use.
- In one embodiment, the polyether is included in a fabric conditioner. A fabric conditioner composition contains a fabric softener material. In certain embodiments, the softener is a cationic softener selected from among esterquats, imidazolinium quats, difatty diamide ammonium methyl sulfate, ditallow dimethyl ammonium chloride, and mixtures thereof.
- In certain embodiments, the cationic fabric softener is an esterquat. The esterquats of the following formula:
- The esterquat is produced by reacting about 1.65 (1.5 to 1.75) moles of fatty acid methyl ester with one mole of alkanol amine followed by quaternization with dimethyl sulfate (further details on this preparation method are disclosed in
US-A-3,915,867 ). Using this ratio controls the amount of each of monoesterquat, diesterquat, and triesterquat in the composition. In certain embodiments, the alkanol amine comprises triethanolamine. In certain embodiments, it is desirable to increase the amount of diesterquat and minimize the amount of triesterquat to increase the softening capabilities of the composition. By selecting a ratio of about 1.65, the triesterquat can be minimized while increasing the monoesterquat. - Monoesterquat is more soluble in water than triesterquat. Depending on the AI, more or less monoesterquat is desired. At higher AI levels (usually at least 7%), more monoesterquat as compared to triesterquat is desired so that the esterquat is more soluble in the water so that the esterquat can be delivered to fabric during use. At lower AI levels (usually up to 3%), less monoesterquat is desired because during use, it is desired for the esterquat to leave solution and deposit on fabric to effect fabric softening. Depending on the AI, the amount of monoesterquat and triesterquat are adjusted to balance solubility and delivery of the esterquat.
- In certain embodiments, the reaction products are 50-65 weight% diesterquat, 20-40 weight% monoester, and 25 weight% or less triester, which are shown below:
- The percentages, by weight, of mono, di, and tri esterquats, as described above are determined by the quantitative analytical method described in the publication "Characterisation of quaternized triethanolamine esters (esterquats) by HPLC, HRCGC and NMR" A.J. Wilkes, C. Jacobs, G. Walraven and J.M. Talbot - Colgate Palmolive R&D Inc. - 4th world Surfactants Congress, Barcelone, 3-7 VI 1996, page 382. The percentages, by weight, of the mono, di and tri esterquats measured on dried samples are normalized on the basis of 100%. The normalization is required due to the presence of 10% to 15%, by weight, of non-quaternized species, such as ester amines and free fatty acids. Accordingly, the normalized weight percentages refer to the pure esterquat component of the raw material. In other words, for the weight % of each of monoesterquat, diesterquat, and triesterquat, the weight % is based on the total amount of monoesterquat, diesterquat, and triesterquat in the composition.
- In certain embodiments, the percentage of saturated fatty acids based on the total weight of fatty acids is 45 to 75%. Esterquat compositions using this percentage of saturated fatty acids do not suffer from the processing drawbacks of 100% saturated materials. When used in fabric softening, the compositions provide good consumer perceived fabric softness while retaining good fragrance delivery. In other embodiments, the amount is at least 50, 55, 60, 65 or 70 up to 75%. In other embodiments, the amount is no more than 70, 65, 60, 55, or 50 down to 45%. In other embodiments, the amount is 50 to 70%, 55 to 65%, or 57.5 to 67.5%. In one embodiment, the percentage of the fatty acid chains that are saturated is about 62.5% by weight of the fatty acid. In this embodiment, this can be obtained from a 50:50 ratio of hard:soft fatty acid.
- By hard, it is meant that the fatty acid is close to full hydrogenation. In certain embodiments, a fully hydrogenated fatty acid has an iodine value of 10 or less. By soft, it is meant that the fatty acid is no more than partially hydrogenated. In certain embodiments, a no more than partially hydrogenated fatty acid has an iodine value of at least 40. In certain embodiments, a partially hydrogenated fatty acid has an iodine value of 40 to 55. The iodine value can be measured by ASTM D5554-95 (2006). In certain embodiments, a ratio of hard fatty acid to soft fatty acid is 70:30 to 40:60. In other embodiments, the ratio is 60:40 to 40:60 or 55:45 to 45:55. In one embodiment, the ratio is about 50:50. Because in these specific embodiments, each of the hard fatty acid and soft fatty acid cover ranges for different levels of saturation (hydrogenation), the actual percentage of fatty acids that are fully saturated can vary. In certain embodiments, soft tallow contains approximately 47% saturated chains by weight.
- The percentage of saturated fatty acids can be achieved by using a mixture of fatty acids to make the esterquat, or the percentage can be achieved by blending esterquats with different amounts of saturated fatty acids.
- The fatty acids can be any fatty acid that is used for manufacturing esterquats for fabric softening. Examples of fatty acids include, but are not limited to, coconut oil, palm oil, tallow, rape oil, fish oil, or chemically synthesized fatty acids. In certain embodiments, the fatty acid is tallow.
- While the esterquat can be provided in solid form, it is usually present in a solvent in liquid form. In solid form, the esterquat can be delivered from a dryer sheet in the laundry. In certain embodiments, the solvent comprises water.
- AI refers to the active weight of the combined amounts for monoesterquat, diesterquat, and triesterquat. Delivered AI refers to the mass (in grams) of esterquat used in a laundry load. A load is 3.5 kilograms of fabric in weight. As the size of a load changes, for example using a smaller or larger size load in a washing machine, the delivered AI adjusts proportionally. In certain embodiments, the delivered AI is 2.8 to 8 grams per load. In other embodiments, the delivered AI is 2.8 to 7, 2.8 to 6, 2.8 to 5, 3 to 8, 3 to 7, 3 to 6, 3 to 5,4 to 8,4 to 7, 4 to 6, or 4 to 5 grams per load.
- The composition can be provided as a fragrance free composition, or it can contain a fragrance. The amount of fragrance can be any desired amount depending on the preference of the user. In certain embodiments, the total amount of fragrance oil is 0.3 to 3 weight % of the composition. The fragrance can be in free form, encapsulated, or both.
- Fragrance, or perfume, refers to odoriferous materials that are able to provide a desirable fragrance to fabrics, and encompasses conventional materials commonly used in detergent compositions to provide a pleasing fragrance and/or to counteract a malodor. The fragrances are generally in the liquid state at ambient temperature, although solid fragrances can also be used. Fragrance materials include, but are not limited to, such materials as aldehydes, ketones, esters and the like that are conventionally employed to impart a pleasing fragrance to laundry compositions. Naturally occurring plant and animal oils are also commonly used as components of fragrances.
- The composition can contain any material that can be added to fabric softeners. Examples of materials include, but are not limited to, surfactants, thickening polymers, colorants, clays, buffers, silicones, fatty alcohols, and fatty esters.
- The fabric conditioners may additionally contain a thickener. In one embodiment, the thickening polymer is the FLOSOFT™ DP200 polymer from SNF Floerger that is described in United States Patent No.
6,864,223 to Smith et al. , which is sold as FLOSOFT™ DP200, which as a water soluble cross-linked cationic polymer derived from the polymerization of from 5 to 100 mole percent of cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent. A suitable thickener is a water-soluble cross-linked cationic vinyl polymer which is cross-linked using a cross-linking agent of a difunctional vinyl addition monomer at a level of from 70 to 300 ppm, preferably from 75 to 200 ppm, and most preferably of from 80 to 150 ppm.

- 35 cm denim swatches are evaluated during the experiment (35 cm x 35 cm). Up to 5 denim swatches are evaluated per treatment as repetitions in order to avoid the experimental error. The following treatments are tested during the experiment:
- The Passerelle ™ DFD polymer is tested at 0.5, 1, 1.5, and 2 weight % as supplied in the fabric conditioner composition. The percent water retained is shown below compared to a fabric conditioner without the polymer.
Polymer Weight % Water Retention (%) 0.5 % 105.767 1.5 % 106.47 1 % 107.689 2 % 108.767 Control without polymer 111.831 - The Passerelle ™ DP5270 polymer is tested at 0.5, 1, 1.5, and 2 weight % as supplied in the fabric conditioner composition. The percent water retained is shown below compared to a fabric conditioner without the polymer.
Polymer Weight % Water Retention (%) 1 % 105.452 1.5 % 105.62 2 % 106.822 Control without polymer 107.1 0.5 % 108.563 - The reduction of drying time in a tumble drier is determined by measuring the % water retention of denim swatches during drying.
-
- The % Water Retention is plotted during the time of the experiment (Every 30 min).
- Prepare an approximate 2 kg load containing 5 denim swatches (100% cotton denim, 175 cm long, approximately 400 g per swatch) without ballast, per product to be tested (washing machine).
• Using a marking pen, label swatches with respective product identification code.
• Weigh out detergent samples and fabric softener for each wash.
• Washing machine(s) should be cleaned by conducting a wash cycle.Washer Type Front Loading Wash Cycle Custom - 40°C, "Fast" Centrifugation Wash Time 77 minutes Water Level 23 liters used for all wash and rinse cycles Wash Temperature 40°C Rinse Temperature Room Temperature Spin Speed 1200 RPM Laundry Load Size 2 Kg Drying Dryer Detergent Ariel™ Professional detergent from Europe Dosage 80 g Fabric Softener 110 g
• Set wash controls for custom cycle with specified wash period. Add detergent and fabric softener to respective compartments in washing machine. Add swatches to washing machine.
• Start wash cycle
• Wash for specified amount of time - The test is run for 50 minutes, and the percent water retention is measured. Three samples are prepared: a swatch that has no treatment, a swatch treated with fabric conditioner, and a swatch with fabric conditioner containing Passerelle™ DFD at 2% by weight. After 20 minutes of drying, the swatches with Passerelle™ DFD at 2% are almost dry and statistically different versus conditioner treated and water only treatments that are dried for 50 minutes. See data below.
Sample Water Retention (%) Passerelle™ DFD at 2% 3.723 Fabric Conditioner only 15.892 Water only 19.345 - As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range.
- Unless otherwise specified, all percentages and amounts expressed herein and elsewhere in the specification should be understood to refer to percentages by weight. The amounts given are based on the active weight of the material.
