Description

WASHING METHOD TECHNICAL FIELD The present invention relates to a method for improving the softness of an article to be washed, a process for hand washing, a detergent composition, a laundry detergent composition and a creamy appearance softness improver. In addition, the present invention relates to a process for washing an article to be washed with the detergent composition, the laundry detergent composition or the creamy smoothness improver mentioned above.

PREVIOUS TECHNIQUE The washing methods can be broadly classified into two classes: hand washing and washing with washing machine. In recent years, with the widespread use of washing machines, washing with a washing machine tends to be used more and more. However, hand washing is still carried out from the point of view of the ease of removal of dirt stains and economic advantages. While hand washing makes flexible washing conditions possible depending on the washing situations such as the degree of removal of dirt stains and the kinds of items to be washed, physical and mental fatigue is involved in an individual who washes hand, compared with washing with a washing machine. Especially in "scrubbing" where the items to be washed are rubbed against each other, mechanical forces can be applied directly to the sites to be washed, thus being one of the most natural processes for hand washing . However, a prolonged period of work would be fatiguing for an individual who washes by hand. In addition, since the surface of articles to be washed, such as clothing, is not microscopically smooth, resistance is generated when in fact these garments are rubbed together. This resistance is perceived by the individual who washes as unpleasant factors, such as "rough texture" and "squeak" and increases the load physically applied to the individual from the point of view of the exhaustion of physical force by the movement of the wash by rubbing. In addition, the local friction generated during rubbing causes scratches or cuts on the hands of the individual, which in turn appears as wear on the fibers, commonly referred to as "garment damage" on items to be washed. . The damage to the fibers not only shortens the period of wear of the garments but also serves as an acceleration factor with respect to the adherence of dirt stains, thereby further increasing the physical load required for washing. In addition, this rubbing resistance in washing with a washing machine causes damage to the fibers generated by mechanical forces such as agitation, and loss of shape. On the other hand, conventionally, technological developments have been made by referring mainly to the aspect of "how to remove adhering dirt stains from an article to be washed" - such as the improvement of the detergency or power of a detergent or the prevention of the re-deposition on recently washed clothes such as garments or the appearance of "how to prepare freshly washed clothes", such as granting a softening property to recently washed clothes (see, for example, Patent Publications 1, 2, 3 and 4). Taking into consideration the unpleasant factors and the physical load generated during hand washing as mentioned above, ie "the mental and physical load for an individual who washes", until now no technological developments have been made that focus on the improvements to them to reduce the charges.

EFFECTS OF THE INVENTION When using the process to wash an article to be washed, the detergent composition or the laundry detergent composition of the present invention, an effect is exhibited that conventional washing, especially hand washing, can be Carry out at home as a more pleasant experience. Specifically, in accordance with the present invention, some effects are exhibited that reside in that the sensation during hand washing is improved, that at the same time the physical loads are diminished and that the care of the clothes to be washed and a prevention of abrasion.

BEST MODE FOR CARRYING OUT THE INVENTION A conventional detergent component such as a surfactant or a low molecular weight polymer formulated as a dispersant for soils and carbon stains, such as sodium polyacrylate or polyethylene glycol, could show a lubricating effect under special conditions, for example, a highly highly concentrated system (for example, a liquid mixture having a concentration of 100 g / L as a concentration of the base components). However, in a concentration. of a washing liquid which is usually used (for example, a liquid mixture having a concentration of 0.05 to 10.0 g / L as a concentration of the base components), these lubricating effects are not shown or even if there is a slight effect , the effect is insufficient pair? eliminate the disadvantages mentioned above when washing by hand is carried out. For example, it has been shown that some compounds have an effect in reducing friction between fibers, such as the polymers of silicone compounds described in JP-A-Hei-5-508889 mentioned above. However, a user still can not perceive particularly significant changes in the sensation when washing by rubbing with a washing liquid at a concentration usually employed. Therefore, washing by hand does not become a pleasant experience for the user because of the effects of these base components alone. In addition, the polymers of silicone compounds are a kind of oil surface coating agent having an extensibility to reduce friction on the surface of the fibers during drying and these polymers do not provide sufficient effects from the viewpoint of preventing the damage of the fibers generated during scrubbing when the polymers are used in the form of an aqueous solution, i.e. a washing liquid.

In order for hand washing to be carried out as a pleasant experience at home, it is necessary that the softness of an article to be washed can be carried out in a washing liquid at a usual concentration. As a result of intensive studies of the needs to carry out hand washing as a more pleasant experience, the present inventors have discovered that a specific softness can be obtained when rubbing especially the articles to be washed with each other by adding a polymer organic, specific to a washing liquid and carry out the washing by hand and is improved with which the sensation during the hand washing and at the same time the physical load is diminished, obtaining with which also the care of the clothes for wash and care of the hands. Also, the present inventors have discovered that those polymers having specific functional groups among the organic polymers are especially excellent from the point of view of the characteristic to prevent re-deposition of the detergent composition. In addition, the present inventors have discovered that the softness serves to prevent damage to the laundry to be washed during washing of the washing items in a washing machine by adding this organic polymer to a washing liquid and to prevent entanglement and deformation of the laundry. clothes to be washed in the washing machine because the softness is generated between the washing articles and the fibers, thereby providing an effect for the care of laundry to wash such as prevention in the loss of its shape. These and other advantages of the present invention will be apparent from the following description. 1. Method for Improving Softness One of the important features of the method for improving the softness during washing of an article to be washed (later referred to simply as "method to improve softness") of the present invention resides in that the method includes the step of washing the article with a wash liquid under conditions where an organic polymer having spinnability (also referred to herein later as "spinnable organic polymer") is present in the wash liquor. For example, the method can be carried out with a wash liquid that is prepared by pre-adding a detergent composition containing an organic polymer, spinnable to the water to dissolve, or separately adding a spinnable organic polymer to a wash liquor without containing the spinnable organic polymer during washing. The smoothness of the articles to be washed can be markedly improved by using the method having the above characteristic. The term "washing liquid" used herein refers to a water-based liquid composition for carrying out laundry washing, in which a detergent composition is dissolved or suspended. The phrase "improvement of softness" used herein refers to the reduction of friction generated between garments or between fibers or the like in a washing liquid or in a state where the garments or fibers contain the liquid of washing during the wash. Especially during hand washing, the softness can be exhibited as a degree of resistance received (perceived) by the hands of an individual who washes during washing by rubbing the articles to be washed. Therefore, with the improvement of the softness, this reception or perception of the resistance is reduced, so that the articles to be washed can be rubbed against each other very gently. Specifically, the case described below is indicated as "improvement of softness". When a washing liquid has a smaller resistance that is perceived by the hands when they are washed by rubbing with the hands the garments or pieces of clothing, in other words, the softness is even higher and a feeling of squeaking is still smaller in a comparison of two members with a washing liquid that does not contain the organic polymer, it is said that the softness is improved (by means of the use of the washing liquid). At this point, as the washing liquid which does not contain the organic polymer, a washing liquid obtained, for example, can be used upon dissolving the composition obtained in Preparation Example 1-1 according to the method described in e <.; Method for Hand Washing Testing > . Also, as the method for rubbing, the method described in < Method for Hand Washing Testing > . Specifically, an individual who washes according to the method for improving the softness of the present invention obtains a feeling of a smooth "coating" on the surface of the articles to be washed during washing when the fingertips or the like touch the surface. surface. This sensation is exhibited by the spinnable organic polymer that is added to the washing liquid. In this regard, it is presumed that the layer or a part thereof plays an important role as a lubricating layer, so that the articles to be washed that are in contact are considered to provide a "soft" feeling to each other. In the present invention, since this layer exists in the article to be washed during the washing and the "softness" is generated during the scrubbing, a washing can be carried out as a pleasant experience. In addition, an effect is exhibited to suppress the cuts or scratches on the hands that are generated by the rubbing of articles to be washed with the hands (commonly called effect to reduce the abrasion) and an effect to suppress the damage in the fibers of a article to be washed (commonly called effect for care of the damage of clothes to wash). [Definition of Sprayability] The term "spirability" used in this document means a property to show a property of extension of an object, ie a commonly called "viscous" property and a remarkable example thereof includes, for example, the courier (spinnability) of fermented soybeans and the like. The spinnability is a property to show a continuous structure similar to a strand without breaking into droplets when a liquid composition is spilled (or poured) at a low speed or a liquid composition is extended by holding one end of the liquid composition. An example of this includes, for example, the courier of a viscous mucus from animals or plants and the like. Incidentally, the spinnability has been known as a phenomenon of elastic relaon phenomena of the liquid composition and is completely independent of the surface tension: or viscosity. Even in the case of a usual polymeric solution, the polymer solution can frequently show the aforementioned spinnable behavior, as long as the concentration of the polymer is, for example, as high as 100 g / L or more as mentioned above. However, the polymer solution * described above shows that this very high viscosity of the polymer solution is markedly disadvantageous in flowability. The spinnability in the present invention refers to the spinnability that can be exhibited by a liquid water-based composition of a certain organic polymer in a very dilute concentration, while maintaining a high fluidity. [Definition of Organic Polymer Sprayability] The spun-bondable organic polymer used herein refers to an organic polymer of which an aqueous solution shows the spirability in the present invention as mentioned above. This spinnable organic polymer is generally different from the organic polymer with a high molecular weight that exhibits a commonly called "thickening effect". In the present invention, the spinnable organic polymer is preferably an organic polymer of which an aqueous solution with a concentration of 30.0 g / L or less shows spinnability, more preferably an aqueous solution with a concentration of 10 g / L or less shows spinnability and even more preferably an aqueous solution with a concentration of 5 g / L or less shows spinnability. In the present invention, the presence or absence of spinnability of the organic polymer is determined according to the following method. An aqueous mixed solution was prepared by adding to an aqueous solution containing 0.07% by weight of sodium dodecylbenzenesulfonate and 0.07% by weight of anhydrous sodium carbonate., an organic polymer at a concentration such that the viscosity in the aqueous mixed solution is about 500 mPa * s, about 200 mPa * s, about 100 mPa »s or about 20 mPa * s determined with a type B viscometer at 25 ° C C (0 ° DH, 60 r / min). The spinnability of the resulting aqueous mixed solution is judged according to the method described in the following [Judgment Method for Spinning]. When it is judged that the mixed, aqueous solution has spinnability in any solution with the viscosities described above, the organic polymer is considered to be an organic, spinnable polymer.

[Trial Method for Spinning] An aqueous solution that shows mail (spinnability) when spilled gently from the end (inner diameter: 1 mm) of a Pasteur pipette (glass, for example, ASAHITECHNO '.' GLASS, IK-PAS-5P) is defined as an aqueous solution showing spinnability in the present invention. At this point;, a solution showing larger fibers is defined as an aqueous solution having a stronger (or higher) spinnability. The aqueous solution is used in the judging method at 25 ° C after completely stirring the solution and the drop procedure is carried out by placing the end of the Pasteur pipette at least 5 mm away from a point to which the aqueous solution. With respect to the aqueous solution having a strong spinnability, the spinnability can be confirmed more easily when the spill procedure is carried out from an even higher position. The spill procedure can be carried out several times and confirmed.

The "fiber" confirmed during the spill procedure is a fiber that is thinner than 1 mm in diameter. This spinnability can also be determined by means of equipment such as Capillary Breakup Extensional Rheometer (CaBERl), manufactured by Thermo HAAKE. The higher the effect for providing the spinnability, specifically the higher the spinnability of the polymer, the "softness" can be brought into effect at a proposed, even lower concentration. When the washing liquid has spinnability, an even higher "softness" can be carried out. Even in the case where it is not found that a washing liquid has spinnability, by adding a polymer having the ability to provide spinnability to an aqueous solution to a washing liquid, the proposed "softness" can be obtained. The spinnable organic polymer of the present invention is a compound not usually used in a < -Detergent composition. The spinnable organic polymer includes crosslinkable polymers and non-crosslinkable polymers. Among the spinnable organic polymers, the non-crosslinkable polymer has a higher spinnability and is preferable in the present invention. Specific examples of the spinnable organic polymer include a polymer or copolymer made from one or more monomers selected from the group consisting of ethylene oxide, acrylic acid, acrylamide, 2-acrylamide-2-methylpropanesulfonic acid, dimethylaminoethyl-methacrylic acid, vinyl alcohol and amino acids such as glutamic acid and aspartic acid; a polysaccharide having a sugar main structure such as starch, hydroxyethylcellulose (HEC), carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC) and hyaluronic acid.

Among these, the polymer or copolymer made from one or more monomers selected from the group consisting of ethylene oxide, acrylic acid, acrylamide, 2-acrylamide-2-methylpropanesulfonic acid, dimethylaminoethyl methacrylic acid, vinyl alcohol, amino acids such as glutamic acid and aspartic acid; and a polysaccharide having a sugar main structure such as starch, hydroxyethylcellulose (HEC) or hydroxypropylmethylcellulose (HPMC). An acrylic acid polymer or a salt thereof, an acrylamide polymer, a 2-acrylamide-2-methylpropanesulfonic acid polymer or a salt thereof, a copolymer of acrylic acid and a 2-acrylamide-2-methylpropanesulfonic acid or a salt thereof, a polyethylene oxide and hydroxypropylmethylcellulose are more preferable. From the point of view of advantage, economic and the like, the acrylic acid polymer or a salt thereof, an acrylamide polymer, the 2-acrylamide-2-methylpropanesulfonic acid polymer or a salt thereof, the acid copolymer Acrylic and 2-acrylamide-2-methylpropanesulfonic acid or a salt thereof and polyethylene oxide are preferable. At this point, the polyethylene oxide exhibits high smoothness as the spinnable polymer of the present invention. Nevertheless, the polyethylene oxide loses its ability to grant softness by a specific interaction in co-presence with a polyoxyethylene alkyl ether, which is a non-ionic surfactant, in the washing liquid. Therefore, in the method for improving the softness of the present invention, when the spinnable organic polymer is a polyethylene oxide, the washing liquid does not consist essentially of polyoxyethylene alkyl ether. It is preferable that the washing liquid does not consist essentially of polyoxyalkylene alkyl ether and polyoxyethylene alkyl phenyl ether. The expression "does not consist essentially of" used herein means that the compound is contained at a wash liquor concentration of 100 mg / L or less. It is more preferable that the compound be contained at a concentration of 70 mg / L or less, more preferably 50 mg / L or less, more preferably 30 mg / L or less and much more preferably not contained in the washing liquid. Also, the weight ratio of the compound to the polyethylene oxide is preferably 12 times or less, more preferably 10 times or less, more preferably 5 times or less, more preferably 1 time or less, and most preferably not contained. the washing liquid. Incidentally, the acrylic polymer, crosslinkable (Aqupec manufactured by Sumitomo Seika Co., Ltd., Carbopol manufactured by BF Goodrich and the like), which is used as a thickening agent for a liquid detergent or the like in many cases, it is one in which the spinnability is suppressed even in a thickening system where its aqueous solution shows thixotropic properties, which are judged to be the organic polymer having no spinnability in the present invention. The spinnable organic polymer can be alone or together with another compound formed in a preparation as a creamy appearance softness improver, from the standpoint of the separate aggregation of the spinnable organic polymer to other detergent components. In addition, the spinnable organic polymer can be used alone or two or more kinds of the organic polymers can be used simultaneously as a softness enhancer of creamy appearance. In addition, these spinnable organic polymers can be added by including the organic spinnable polymer in the detergent composition. In the method for improving the softness of the present invention, the amount of the spinnable organic polymer that is present in the wash liquid is preferably 2 mg / L or more, more preferably 5 mg / L or more, still more preferably 10 mg / L or more, still more preferably 20 mg / L or more and even more preferably 50 mg / L or more, from the point of view of providing softness. The timing for the addition of the spinnable organic polymer to the washing liquid is not particularly limited and includes immediately before washing by hand, during hand washing, before starting impregnation when soaking and washing and the like. In addition, the method for adding a spinnable organic polymer includes a method that includes the step of adding the polymer as is; a method that includes the step of adding a solution prepared by previously dissolving the polymer to a solvent such as water; a method that includes the step of mixing the polymer with other compounds to form a preparation in the form of powder, liquid, gel or the like and adding the preparation; a method that includes the step of granulating the polymer; a method that includes the step of incorporating the polymer into a detergent composition in each liquid form, gel, paste, powder, granule or a product molded in secondary passages, such as a tablet or in the form of a paste; and similar. The detergent composition containing a spinnable organic polymer can be added to the water to be dissolved and thus provide a wash liquid or a spinnable organic polymer can be added to a wash liquid that is previously prepared according to the aforementioned method. In either case, the amount of detergent composition in the washing liquid is not particularly limited. When a detergent composition containing a spinnable organic polymer can be added to the water to dissolve and thus provide a washing liquid, the process for preparing the detergent composition containing an organic, spinnable polymer is not particularly limited. The detergent composition can be prepared according to the methods described in Tokkyocho Koho: Shuchi Kanyo Gijutsu Shu (Clothes Powder Detergent: Japanese Patent Office), 10 (1998) -25 (7159) and publication JP-B-3123757, which they have been known as general processes for preparing detergent compositions. Alternatively, the detergent composition can be made by preparing detergent components other than the spinnable organic polymer according to the aforementioned methods and then mixing the resulting detergent composition with the spinnable organic polymer. During mixing, the spinnable organic polymer can be granulated alone and mixed or can be granulated together with other compounds to provide a granular powder and then mixed or can be prepared in liquid or gel form and then mixed. During mixing, the different components of the spinnable organic polymer contained in the detergent composition and the form of the detergent composition are not particularly limited. In the method for providing softness of the present invention, the environments for carrying out the washing, the kinds of articles to be washed, the amount of an article to be washed, the amount of the washing liquid and additionally the size of a container , the in case the washing is carried out in a container, and the like are not particularly limited. For example, when a basin or basin is used, the larger the sink, the larger the amount of wash liquid and the smaller the object-liquid ratio (weight ratio of the item to be washed / washing liquid), the softness will be more easily recognizable. In terms of size, the sink is preferably one having a diameter of 25 cm or more, more preferably 30 cm or more, even more preferably 40 cm or more and even more preferably 50 cm or more. The object-liquid ratio is preferably 1/3 or less, more preferably 1/5 or less, still more preferably 1/7 or less and even more preferably 1/10 or less. In addition, the higher the temperature, the solubility will be more excellent in many of the spinnable organic polymers. Also, the temperature of the washing liquid is preferably 10 ° C or higher, more preferably 20 ° C or higher, still more preferably 25 ° C or higher and even more preferably 30 ° C or higher. In addition, the method for hand washing is not particularly limited as long as it is a method for hand washing an article to be washed. 2. Process for Hand Washing In addition, the present invention relates to a process for hand washing. A preferred process for hand washing in the present invention (hereinafter referred to as "hand washing process of the present invention") is one in which the method for improving the smoothness of the present invention includes step that consists in washing by hand an article to be washed with a washing liquid showing the sprayability used in the present invention as described below, is applied to the process. By carrying out the hand washing process mentioned above, a highly excellent effect can be obtained to improve the softness. According to the process for hand washing, an effect is exhibited that resides in that the sensation is improved, so that hand washing is carried out as a pleasant experience. In addition, a so-called effect to prevent abrasion is exhibited, an effect to suppress cuts, scratches and the like in the hands that are generated by rubbing with the hands of an article to be washed and a commonly called effect for the care of the damage of clothes to wash, an effect to suppress the damage in the fibers and similar of an article to be washed. The wash liquor in the hand washing process of the present invention relates to (i) a wash liquid that exhibits spinnability during hand washing containing the spinnable organic polymer, or (ii) a wash liquid that it is prepared by diluting the previous washing liquid (i) with more than 1 to 1,000 times the amount of water. At this point, although the washing liquid which is prepared by diluting the washing liquid having spinnability with more than 1 to 1,000 times the amount of water does not show spinning for any longer in some cases, since the organic polymer that can be the present invention showing lubricity is also present in a liquid layer between the garments in the washing liquid, the effect mentioned above for improving the softness of the present invention can be carried out during hand washing. Therefore, the washing liquid showing the spinnability of the present invention is in essence completely different from an aqueous solution of which the viscosity or a diluted solution thereof is simply increased. The presence or absence of spinnability of the wash liquid is judged according to the method described in [Judgment Method for Spinning] above. The washing liquid which shows spinnability can be obtained, for example, by adding a spinnable organic polymer to a washing liquid as part of the detergent components or separately from the detergent components. In the present invention, the higher the molecular weight of the spinnable organic polymer or the higher the content of the spinnable organic polymer in the wash liquid, the more enhanced the effect for improving the softness, taking effect with which the washing as a more pleasant experience. The washing liquid showing spinnability in the present invention can be used in the wash after diluting the washing liquid (i) as mentioned above. The concentration after dilution is preferably 1 / 1,000 or more of the lower limit of the concentration that shows spinnability. More preferably 1/500 or more, still more preferably 1/200 or more, still more preferably 1/100 or more, even more preferably 1/50 or more and even more preferably 1/20 or more, from the viewpoint of Smoothness improving effect. In addition, in order to obtain a still higher effect for improving the softness, it is preferable that the washing liquid showing the spinnability of the present invention be used under conditions of concentration where the spinnability is sufficiently shown. The concentration of the wash liquid is preferably 500 times the amount or less of the lower limit of the concentration showing spinnability, more preferably 100 times the amount or less, more preferably 50 times the amount or less, even more preferably 20 times the amount or less, still more preferably 10 times the amount or less, even more preferably 5 times the amount or less, even more preferably 2 times the amount or less and even more preferably 1 time the amount or less, from the point of view of the property of handling of the washing liquid and the economic advantage. The concentration of the spinnable organic polymer in the wash liquid is preferably 2 mg / L or more, more preferably 5 mg / L or more, still more preferably 10 mg / L or more, even more preferably 20 mg / L or more and still more preferably 50 mg / L or more, from the point of view of obtaining a high effect to improve softness. In addition, the concentration of the spinnable organic polymer in the wash liquor is preferably 5,000 mg / L or less, more preferably 2,500 mg / L or less, still more preferably 1,000 mg / L or less, still more preferably 500 mg / L or less and even more preferably 250 mg / L or less, from the point of view of the handling property as a solution. The pH of the washing liquid is preferably 9.0 or more, more preferably 9.5 or more and even more preferably 10.0 or more, from the detergency point of view. At this point, the pH of the washing liquid is determined in a washing liquid having water hardness of 0 ° DH at a temperature of 25 ° C without supplying the garments therein. The upper limit of the pH is preferably 11.0 or less, from the standpoint of stability, prevention of cracked hands and the like. The washing liquid used in this document refers to a solution for carrying out the washing in which a detergent composition is dissolved, suspended or the like. At this point, the different components of the organic polymer contained in the detergent composition, the form of the detergent composition and the process for preparing the detergent composition are not particularly limited and may be the same as those used in the aforementioned method to improve the smoothness.

Further, in the properties of the polymer having a sulfonic acid group and / or a sulfuric acid group, the preferable properties for exhibiting "softness" is "spinnability". The higher the spinnability of the polymer, the smaller the amount of the polymer formulated, so that the "softness" can be brought into effect. In the present invention, a "high spinnability" means that an aqueous solution having a lower concentration or an aqueous solution having a low viscosity exhibits spinnability. The higher the molecular weight and the lower the crosslinking property of the linear polymer, the greater the spinnability, exhibiting an excellent "softness" and is a preferable polymer in the present invention.

In other words, the phrase "organic polymer having an average molecular weight of 1,500,000 or more" refers to an organic polymer of which the maximum, maximum molecular weight is 1,500,000 or more in terms of reduced molecular weight in terms of PEO. [Conditions of Determination for the GPC method] The column used is PW / GMPWXL / GMP XL (manufactured by Tosoh Corporation), the eluent used is phosphate buffer 0.2 M (KH2P04, Na2HP04, pH = 7) / CH3CN = 9 / 1 (weight ratio), the temperature of the column ee 40 ° C, the flow rate is 1.0 mL / minute and the concentration of the sample is from 1 to 100 μg / mL.

When the creamy smoothness improver of the present invention is added to a general detergent composition to provide the detergent composition of the present invention, the process for adding the creamy smoothness improver of the present invention is not particularly limited. . In order to stably exhibit a sufficient effect as the creamy smoothness improver, the process for the addition capable of homogeneously dispersing the creamy smoothness improver of the present invention in the detergent composition at a level practical is preferable in the steps of preparation for the detergent composition.

Although the process for preparing the polymeric particles containing a sulfonic acid group and / or a sulfuric acid group is not particularly limited, the polymerization of reverse phase suspension is preferable from the viewpoint of obtaining a polymer powder or granular which has the particle size mentioned above. Further, in order that the spinnable organic polymer or the sulfonic acid group containing polymer and / or a sulfuric acid group suppress the generation of a pasty mass, the polymer can be used as a mixture of other base components by means of - of this granulation.

After 30 seconds from the start of the shaking, a 100% cotton shirt (white, made by Gunze, large size) was soaked in the washing liquid in the wash tub so that the entire shirt was sufficiently soaked. Five minutes later, the chest portions of the shirt were held in both hands and the chest portions of the shirt were rubbed together. The portions were rubbed together when removing the t-shirt from the washing liquid. After rubbing together for every 3 to 5 times, the rubbed portions were temporarily soaked in the wash liquid.
