Definitions
- the present invention relates to a method of laundering to provide a substantially wrinkle-free textile surface.
- the present invention relates to a method of laundering to provide a substantially wrinkle-free textile surface without ironing or pressing.
- Wrinkles can cause an unacceptable and unprofessional appearance on textile surfaces, including, for example, wearing apparel, flat goods, and other textiles.
- uniforms e.g. chef coats, uniforms for waitresses, factory workers, automotive shops, etc.
- flatware e.g. bed sheets, table clothes, etc.
- Wrinkles often develop on textiles during washing and in subsequent processing and storing. The rigorous process of washing the textiles, particularly in the commercial setting, subjects the textiles to bending and folding.
- wrinkles may be introduced onto the textiles during the extraction cycle (high speed spin cycle) of a washing process or when the textiles are extracted using a hydraulic press following washing in a continuous batch washer. Even with proper cool down procedures, wrinkles can develop, especially in contained textiles. The wrinkles thus need to be completely removed in the subsequent finishing process.
- the textiles are sent through a series of aqueous baths where they are exposed to various chemicals needed either to clean the textiles or to achieve a desired quality for the garments, such as softness, fresh scent, water repellency, etc.
- the textiles go through a finishing process.
- garments may be sent through a finishing tunnel and flat goods may be sent through some type of finishing equipment such as an ironer.
- Garments are frequently exposed to steam and hot air in the finishing tunnel where the steam and hot air function to dry and condition the garments.
- the most common methods of removing wrinkles from garments containing cotton include ironing or pressing the textile.
- the textiles are partially dried ('conditioned') before a final ironing or pressing step.
- Ironing or pressing the textiles is accomplished by manually inserting the textile into the processing unit, or in the case of garments, manually placing them on hangers.

- the chemicals may also be dispensed as separate products or as combination product, such as a product containing both souring agents and softening agents or a product containing souring agents, softening agents, and fabric relaxants.
- the chemicals may be dispensed simultaneously or sequentially into the same bath by employ
- a souring agent may be added to the textile such that the pH of the textile approximately matches the proper processing pH.
- the souring agent is a mild acid used to neutralize residual alkalines and reduce the pH of the textile such that when the garments come into contact with human skin, the textile does not irritate the skin.
- suitable souring agents include, but are not limited to: phosphoric acid, formic acid, acetic acid, hydrofluoro silicic acid, saturated fatty acids, dicarboxylic acids, tricarboxylic acids, and any combination thereof.
- saturated fatty acids include, but are not limited to: those having 10 or more carbon atoms such as palmitic acid, stearic acid, and arachidic acid (C20).

- tricarboxylic acids include, but are not limited to: citric acid and tricarballylic acids.
- approximately 12 milliliters of souring agent is added to approximately 22 pounds of textiles. In general, the dosage of such souring agents will depend on the concentration of the active ingredient (i.e.
- a fabric relaxant may be applied to the textile surface.
- the fabric relaxant is added during the final rinse cycle of the wash process to ensure that the fabric relaxant is neither washed nor rinsed off during subsequent rinsing steps.
- the fabric relaxant may be added to the textile either once or numerous times during the wash process.
- the fabric relaxant is typically applied in either an aqueous- based carrier or a solvent-based carrier. In one embodiment, approximately 15 milliliters of fabric relaxant is added to approximately 22 pounds of textiles.
- An example of a suitable fabric relaxant is a functionalized polydimethylsiloxane polymer.
- the polydimethylsiloxane polymer features one or more positively-charged functional group (e.g.
- the positively-charged functional group may be part of the backbone of the polydimethylsiloxane polymer or part of a side chain of the polymer.
- the positively- charged functional group is preferably attached at an end of the polydimethylsiloxane polymer such that the positively-charged group is more accessible. It is also believed that the hydrophobicity of the fabric relaxant also affects the smoothness of the textile.
- the hydrophobicity of the fabric relaxant is significant because it allows deposition of a chemical out of an aqueous solution onto the textile surface.
- the presence of molecules having mostly dimethylsiloxane backbones are desired in the fabric relaxant because of the hydrophobic nature of methyl groups.
- Particularly suitable examples of fabric relaxants include, but are not limited to: polyfunctional polydimethylsiloxane, polydimethylsiloxane diquaternary ammonium, and poly quaternary polydimethylsiloxane copolyol derivatives.
- Suitable commercially available fabric relaxants include, but are not limited to: Tegopren 6922 (a.k.a. Rewoquat SQl), available from Degussa/Goldschmidt Chemical Corporation, Hopewell, VA; Tinotex CMA, available from Ciba Specialty Chemicals Corporation, Greensboro, NC; and Formasil 888, available from GE Silicones, Wilton, CT.
- the polydimethylsiloxane polymer having a positively-charged functional group may also include at least one alkoxy group. Examples of alkoxy groups include, but are not limited to: ethoxy, propoxy, butoxy, and longer alkoxy groups.
- the fabric relaxant will be substantially free of chemicals such as, but not limited to: surfactants, bleaches, and builders.
- Surfactants, bleaches, and builders need to be rinsed from the textile surface prior to being used due to their detrimental effect on the textile surface when left on the textile surface for an extended period of time.
- residual surfactants in the textile surface can cause the textile surface to have a soapy feel and residual bleach can damage the textile surface.
- Residual builders in the textile surface can increase the pH of the textile surface.
- textiles having a high pH can be a skin irritant.
- the fabric relaxant is substantially free of these chemicals in order to avoid their potentially detrimental effects.
- a fabric softener may also be added to the textile either together with the fabric relaxant or in a separate step. In one embodiment, approximately 15 milliliters of fabric softener is added to approximately 22 pounds of textiles. However, the dosage of the fabric softener may vary with the type and the concentration of the active ingredient.
- An example of a suitable commercially available fabric softener includes, but is not limited to, TurboFresh, available from Ecolab Incorporated, Saint Paul, MN.
- the process of adding fabric softener and fabric relaxant to the textile is generally carried out in the final wash operation, which lasts from between approximately 4 minutes and approximately 7 minutes. Subsequently, all of the water is extracted from the washer and the textiles are removed from the washer for further finishing/drying procedures.
- the textile Before drying the textile, the textile may optionally be conditioned in a dryer.
- the textile may be placed in a dryer for a short period of time to eliminate some of the water absorbed into the textile during the washing and rinsing processes.
- the textile is discussed as being conditioned in a dryer, the textile may be conditioned by any method known in the art without departing from the intended scope of the present invention.
- the final step of the laundering process is steam drying of the textile by sending the textile through a steam tunnel.
- the length of time the textile spends within the steam tunnel depends on a variety of factors, including, but not limited to: the length of the steam tunnel, the mechanical condition of the steam tunnel, and the available steam.
- the textiles are exposed within the steam tunnel for between approximately 4 minutes and approximately 8 minutes.
- AATCC American Association of Textile Chemists and Colorists

- Examples 1, 2, and 3 and Comparative Examples A, B, and C The fabric relaxants used in Examples 1, 2, and 3 included a functionalized polydimethylsiloxane polymer having at least one positively-charged functional group as the fabric relaxant during the washing process.
- the fabric relaxants of Comparative Examples A, B, and C used various other polymers.
- Table 1 provides the fabric relaxant used during the washing process and the smoothness appearance of the textiles after being washed and dried, as analyzed pursuant to the method discussed above, for the compositions of Examples 1, 2, and 3 and Comparative Examples A, B, and C.
- Examples 1, 2, and 3 and Comparative Examples A, B, and C were tested for the appearance of smoothness, which is illustrated by the data provided in Table 1, after the textiles were washed and passed through a steam tunnel.
- the textiles of Examples 1 and 2 had superior smoothness ratings and the textiles of Example 3 had an acceptable smoothness rating.
- the textiles of Comparative Example A, Comparative Example B, and Comparative Example C exhibited unacceptable smoothness appearance ratings.
- the polydimethylsiloxane polymers must adhere to the textile surface. This may be achieved by exposing the textiles to elevated temperatures in order to crosslink the polymers.
- a positively-charged functional group can assist in anchoring the polydimethylsiloxane polymer to the surface of the textile.
- the positively-charged functional group, or cationic group will be attracted to the negatively charged textile and facilitate in adhering the polydimethylsiloxane polymers to the textile surface.
- the textiles of Examples 1 and 2 had superior smoothness appearance ratings. It is believed that this is due to the presence of positively-charged functional groups in the polydimethylsiloxane polymer present in the fabric relaxant.
- the fabric relaxant of Example 1 contained 50% active polydimethylsiloxane diquaternary ammonium and the fabric relaxant of Example 2 contained polyfunctional (cationic/nonionic) polydimethylsiloxane.
- the structure of the fabric relaxant of Example 1 includes a cationic group at each end of the dimethylsiloxane polymer molecule (U.S. Patent No. 4,891,166), making them easily accessible.
- the structure of the fabric relaxant of Example 1 also includes dimethylsiloxy groups, which are very hydrophobic because of the methyl groups. Generally, molecules that have mostly dimethylsiloxane backbones are more hydrophobic. Hydrophobicity of the fabric relaxant is also important because the more hydrophobic the chemical is, the easier it is to precipitate the chemical out of an aqueous solution. Thus, without being bound by theory, it is believed that both the presence of terminal cationic anchors and the hydrophobicity of the fabric relaxant are important in adhering the polydimethylsiloxane polymers to the textile surface and increasing the smoothness of the textile surfaces.
- the textiles washed using the fabric relaxant of Example 3 had an acceptable smoothness appearance rating, although slightly less acceptable than Examples 1 and 2. While the fabric relaxant of Example 3 also contained a polydimethylsiloxane polymer with at least one positively-charged functional group, the fabric relaxant of Example 3 contained 80% active polyquaternary polydimethylsiloxane copolyol. In addition, it is believed that, due to the copolyol part of the polymer, the fabric relaxant of Example 3 was slightly more hydrophilic than the fabric relaxants of Examples 1 and 2, as measured in terms of solubility and miscibility with water.
- A, B, and C were observed to have unacceptable smoothness appearances. It is believed that the smoothness appearances of the textiles were affected by the reduced presence, or lack of, at least one positively-charged functional group in the polydimethylsiloxane polymers present in the fabric relaxant as well as the hydrophilicity of the fabric relaxants. Without sufficient numbers of positively-charged functional groups, it is believed that the polydimethylsiloxane polymers were not able to anchor to the textile surfaces strongly enough to be effective. In addition, the more hydrophilic the fabric relaxant, the more difficult it is to precipitate out the chemical from the aqueous solution. Thus, rather than having a smooth appearance, the textiles of Comparative Examples A, B, and C had a stiff and wrinkled appearance.
- the fabric relaxants of Comparative Examples A and B included polydimethylsiloxane polymers, the polymers did not have any positively- charged functional groups.
- the fabric relaxant of Comparative Example A contained 60% active nonionic polysiloxane. It is also believed that the nonionic polysiloxane was ineffective due to the need for elevated temperatures for cross-linking.
- the fabric relaxant of Comparative Example B contained 100% amino polydimethyl siloxane, also a nonionic polymer, and did not have much effect on the textiles.
- the fabric relaxant of Comparative Example C did contain some positively-charged functional groups.
- the fabric relaxant of Comparative Example C contained 40% of a blend of silicone carboxylate and amino- silicate functional component that is cationic.
- the surface of the textile was still observed as unacceptable after washing and drying. This is believed to be due to the presence of carboxylate groups (silicon carboxylate) in the fabric relaxant.
- Carboxylate groups are negatively charged (anionic) at neutral pH and are also very hydrophilic. It is believed that the carboxylate groups hinder attachment of the polydimethylsiloxane polymers to the textile surface because the anionic charge of the carboxylate groups eliminates the cationic charge of the positively-charged functional group.
- the fabric relaxant of Comparative Example C did contain at least one positively-charged functional group, its effect was negated by the carboxylate groups.
- hydrophobicity lacking in the fabric relaxant of Comparative Example C, facilitates attachment of polydimethylsiloxane polymers to the textile surface.
- the hydrophilic nature of the carboxylate groups caused the fabric relaxant of Comparative Example C to perform poorly.
- Example 1 and Comparative Example D tested the same fabric relaxant (Tegopren 6922)
- Example 2 and Comparative Example E tested the same fabric relaxant (Tinotex CMA)
- Example 3 and Comparative Example F tested the same fabric relaxant (Formasil 888).
- ml milliliters
- Examples 1, 2, and 3 were passed through a steam tunnel where the textiles were heated to a temperature of between approximately 260 0 F and approximately 280 0 F. Comparative Examples D, E, and F were only allowed to air dry for a predetermined amount of time and were not passed through a steam tunnel.
- Table 2 provides the fabric relaxant used during the washing process, the method of drying, and the smoothness appearance of the textiles after being washed and dried, as analyzed pursuant to the method discussed above, for the compositions of Examples 1, 2, and 3 and Comparative Examples D, E, and F.
- Example 1 After it was determined that the fabric relaxants of Examples 1, 2, and 3 gave superior and acceptable smoothness ratings, the methods of drying the textiles were tested and observed. In particular, Examples 1, 2, and 3 were sent through a steam tunnel while Comparative Examples D, E, and F were only allowed to air dry. As can be seen in Table 2, the textiles that were sent through the steam tunnel exhibited a higher smoothness rating than the textiles that were only allowed to air dry. After being passed through the steam tunnel, Examples 1 and 2 were observed to have superior smoothness ratings and Example 3 was observed to have an acceptable smoothness ratings.
- Comparative Examples D, E, and F were only allowed to air dry and received very weak smoothness ratings. This is because in order to achieve a smooth surface, the polydimethylsiloxane polymers must adhere to the textile surface.
- One method of anchoring the functionalized polydimethylsiloxane polymers to a textile surface is to apply elevated temperatures to the textile surface to crosslink the polymers.
- the elevated temperatures can be reached by methods such as ironing or pressing the textile surface.
- the ironing and pressing processes are both time-consuming and labor intensive. By passing the textiles through a steam tunnel, the appropriate elevated temperatures may be reached without expending undue time or effort.
- One of the main factors that affects the smoothness appearance level of recently cleaned and dried textiles is the presence of one or more positively-charged functional groups in the polydimethylsiloxane polymers. It is also believed that the hydrophobicity of the fabric relaxant also affects the smoothness of the textile.
- the presence of a polydimethylsiloxane polymer having at least one positively-charged functional group increases the smoothness appearance of cleaned and dried textiles by facilitating attachment of the polydimethylsiloxane polymer to the textiles.
- the high hydrophobicity of the fabric relaxant also enhances the smoothness appearance of textiles by efficiently depositing a chemical out of an aqueous solution onto the textile surface. By eliminating the need to iron or press the textiles after cleaning and drying, process times and capital cost for acceptable smoothness appearances of textiles can be decreased.
