Description

SPECIFICATION

[Title of Invention] Liquid treatment composition for textile product [Technical Field] [0001] The present invention relates to a liquid treatment composition for textile products, in particular to a liquid treatment composition suitably used for textile products such as clothes and the like. More particularly, the invention relates to a liquid treatment composition for textile products that is excellent in the effects of inhibiting a change of fragrance tone and improving the fragrance remaining property.

[Background Art]

[0002] Various trials for improving the fragrance remaining property of the fabric treatment agent have been made these years in response to an increasing demand for the products with strong fragrance.

By way of example, there is proposed a method for allowing a larger amount of perfume present in a wash tub to leave on the cloth after treatment with the fabric treatment and enhancing the fragrance remaining property of the perfume by increasing the amounts of perfume ingredients with high ClogP values in a perfume composition used for the fabric treatment agent (JP3102893). However, use of only the perfume ingredients with high ClogP values makes the fragrance tone of the textile products boring after the textile products are dried, which cannot meet the consumers' demands. Further, the kinds of perfume ingredients with high ClogP values are limited, and most of them are expensive, so that this proposal is economically disadvantageous.

The perfume ingredients having low ClogP values are less retained on cloths than the perfume ingredients having high ClogP values. As a result, when the perfume ingredients with low ClogP values are used, the originally designed fragrance tone of the treatment composition is apt to change after the fabric treatment. To solve this problem, JP 2009-144306 A discloses a technique that allows the perfume ingredients with low ClogP values to attach to the cloth. However, the technique involves complicated steps because it is necessary to provide a step of synthesizing a particular polymer that is used in combination with the perfume ingredients with low ClogP values. Further, the above-mentioned technique is not intended to prevent the fragrance tone from changing. Although perfume ingredients that can considerably contribute to a change of fragrance tone are ones with low ClogP values, as mentioned above, a change of fragrance tone is a problem ascribed to the perfume formulation as a whole including the perfume ingredients with high ClogP values.

[0003] JP 2011-127260 A discloses a treatment composition for textile products comprising a particular silicic acid ester. According to the disclosure, it is necessary to use as a perfume compound a silicic acid ester having a logP of 1 or more and less than 15 in combination with a silicic acid ester having a logP of 15 or more and less than 50 as another perfume compound. The process for preparing the perfume composition by the silicic acid ester compounds is required, which makes the steps complicated. Thus, there still remains the problem of change of fragrance tone.

[Summary of Invention]

[0004] An object of the invention is to provide a liquid treatment composition for textile products that can bring excellent effects of inhibiting a change of fragrance tone and improving the fragrance remaining property.

[0005] The inventors of the invention found that a perfume, to be more specific, a perfume ingredient with a low ClogP can be more retained on cloths after the treatment and therefore the fragrance remaining property can be improved and a change of fragrance tone can be inhibited by using a particular glucan called a highly branched cyclic dextrin in combination with perfume ingredients in a liquid treatment composition for textile products.

[0006] The invention has been accomplished based on such novel findings as mentioned above.

[0007] Accordingly, the invention provides a liquid treatment composition for textile products, comprising; (A) a perfume composition, (B) a glucan comprising an inner branched cyclic structure portion and an outer branched structure portion and having a degree of polymerization of 50 to 10,000, the inner branched cyclic structure portion being a cyclic structure portion formed from a-1,4-glucoside bond and a-1,6-glucoside bond, and the outer branched structure portion being a non-cyclic structure portion attached to the inner branched cyclic structure portion, and (C) a cationic surfactant.

[0008] According to one aspect of the invention, the component (A) comprises a perfume ingredient having a ClogP of 5 or less or a perfume ingredient comprising a cyclic structure in its structure.

[0009] According to another aspect of the invention, the component (C) is selected from the group consisting of amine compounds having in the molecule thereof 1 to 3 hydrocarbon groups with 10 to 26 carbon atoms, which may be separated by an ester group or an amide group, salts thereof and quaternary compounds thereof.

[0010] The liquid treatment composition for textile products according to the invention employs a perfume composition as the component (A) in combination with a highly branched cyclic dextrin as the component (B), so that the perfume ingredients, in particular, perfume ingredients with low ClogP values can be more retained on cloths after the treatment and therefore the fragrance remaining property can be improved and a change of fragrance tone can be inhibited.

[0014] In the liquid treatment composition for textile products according to the invention, it is preferable to use as the component (A) a perfume composition comprising a perfume ingredient having a ClogP of 5 or less, which may be contained in an amount of preferably 10 mass% or more, more preferably 30 mass% or more, still more preferably 50 mass% or more, and particularly preferably 70 mass% or more, with respect to the total mass of the perfume composition.

More advantageously, the liquid treatment composition for textile products according to the invention may comprise a perfume composition comprising a perfume ingredient having a ClogP of 5 or less and a cyclic structure. Particularly, in the liquid treatment composition for textile products according to the invention, it is preferable that a perfume composition comprise a perfume ingredient having a ClogP of 5 or less and a cyclic structure in an amount of 20 mass% or more, and more preferably 40 mass% or more.

The cyclic structure herein used may be a hydrocarbon cyclic structure or heterocyclic structure, which may be a monocyclic or polycyclic structure including condensed polycyclic structure, bridged cyclic structure or spiro ring structure. Those cyclic structures may be saturated or unsaturated. The hetero ring may contain, for example, 0, S, N and P as the hetero atoms.

Specifically, the cyclic structure may include monocyclic compounds such as benzene and the like, and condensed ring compounds such as naphthalene and the like. In terms of the atoms constituting the cyclic structure, carbocyclic compounds or heterocyclic compounds may be used. As for the ring size, five-membered cyclic compounds such as cyclopentane, furane and the like, six-membered cyclic compounds such as cyclohexane, benzene and the like, and any other cyclic compounds may be used.

[0015] In the liquid treatment composition for textile products according to the invention, specific examples of the perfume ingredient that can preferably be used in the component (A) include Iso E Super (having a ClogP of 4.7 and a cyclic structure); ethylvanillin (having a ClogP of 1.8 and a cyclic structure); y-undecalactone (having a ClogP of 3.8 and a cyclic structure); eugenol (having a ClogP of 2.4 and a cyclic structure); f3-damascone (having a ClogP of 4.7 and a cyclic structure); helional (having a ClogP of 1.4 and a cyclic structure); benzyl salicylate (having a ClogP of 4.2 and a cyclic structure); cashmeran (having a ClogP of 4.0 and a cyclic structure); coumarin (having a ClogP of 1.4 and a cyclic structure); dimethylbenzylcarbinyl acetate (having a ClogP of 1.9 and a cyclic structure); terpineol (having a ClogP of 2.6 and a cyclic structure); damascenone (having a ClogP of 4.3 and a cyclic structure); Triplal (having a ClogP of 2.4 and a cyclic structure); phenylethyl alcohol (having a ClogP of 1.2 and a cyclic structure); hexylcinnamic aldehyde (having a ClogP of 4.9 and a cyclic structure); 13-ionone (having a ClogP of 3.8 and a cyclic structure); Hedion (having a ClogP of 2.4 and a cyclic structure); vertofix (having a ClogP of 5 and a cyclic structure); methyl ionone (having a ClogP of 4.2 and a cyclic structure); limonene (having a ClogP of 4.4 and a cyclic structure); lyral (having a ClogP of 2.2 and a cyclic structure); lilial (having a ClogP of 3.9 and a cyclic structure) and the like. However, the perfume ingredients used in the invention are not limited to the above-mentioned examples. More preferably, Iso E Super, ethylvanillin, y-undecalactone, eugenol, P-damascone, helional, and benzyl salicylate may be used. Particularly preferably, eugenol, 13-damascone, helional, and benzyl salicylate may be used.

[0016] The ClogP value is a value expressed as the logarithm of P (log P) to the base 10 where P is the partition coefficient between 1-octanol/water of a chemical compound representing the ratio of concentrations of the compound in 1-octanol and water at equilibrium. After a chemical structure of a compound is broken down into the constituent components, the ClogP value can be obtained by integration of the hydrophobic fragmental constants, i.e., f values of the fragments (see, for example, Clog 3 Reference Manual Daylightsoftware 4. 34, Albert Leo David Weininger, Version 1, March 1994).

In general, as the ClogP value of the perfume ingredient becomes greater, the hydrophobicity of the perfume ingredient increases. When the contents of the perfume ingredients with small ClogP values are higher in a perfume composition, the resultant perfume composition is considered to be more hydrophilic than a perfume composition comprising more perfume ingredients with large ClogP values.

In the liquid treatment composition for textile products according to the invention, the perfume ingredients having ClogP values of 1.0 or more and 8.0 or less may preferably be contained in an amount of 30 mass% or more, more preferably 45 mass% or more, still more preferably 50 mass% or more, particularly preferably 80 mass% or more, and further particularly preferably 90 mass% or more, with respect to the total mass of the perfume composition in light of the refreshing effect and the personal preference.

[0017] The perfume composition used in the invention may comprise a solvent that is commonly employed in the treatment compositions for textile products, for example, finishing or softening compositions for textile products. Examples of the solvent for use in the perfume composition include acetin (triacetin), IVIN/IB acetate (3-methoxy-3-methyl butyl acetate), sucrose diacetate hexaisobutyrate, ethylene glycol dibutyrate, hexylene glycol, dibutyl sebacate, Deltyl Extra (isopropyl myristate), methyl carbitol (diethylene glycol monomethyl ether), Carbitol (diethylene glycol monoethyl ether), EEG (triethylene glycol), benzyl benzoate (BB), propylene glycol, diethyl phthalate, tripropylene glycol, Avolin (dimethyl phthalate), Deltyl Prime (isopropyl palmitate), dipropylene glycol (DPG), farnesene, dioctyl adipate, tributyrin (glyceryl tributanoate), Hydrolite-5 (1,2-pentanediol), propylene glycol diacetate, cetyl acetate (hexadecyl acetate), ethyl abietate, Abalyn (methyl abietate), Citroflex A-2 (acetyl triethyl citrate), Citroflex A-4 (tributyl acetyl citrate), Citroflex No. 2 (triethyl citrate), Citroflex No. 4 (tributyl citrate), Durafix (methyl dihydroabietate), MITD (isotridecyl myristate), polylimonene (limonene polymer), 1,3-butylene glycol and the like.

These solvents may be contained in the perfume composition, for example, in an amount of 0.1 to 30 mass%, preferably 1 to 20 mass%.

[0018] In the liquid treatment composition for textile products according to the invention, the content of the component (A) is not particularly limited, but preferably may be in the range of 0.01 to 5 mass%, more preferably 0.1 to 5 mass%, and further more preferably 0.5 to 3 mass%, based on the total mass of the treatment composition when the treatment composition is used as a softener composition. When the treatment composition is used as a spray type fabric treatment composition, the content of the component (A) may preferably be in the range of 0.001 to 1 mass%, more preferably 0.005 to 1 mass%, and further more preferably 0.01 to 0.5 mass%, based on the total mass of the treatment composition. When the content of the component (A) is less than 0.001 mass%, the obtainable fragrance is so weak that the effects of inhibiting a change of fragrance tone and improving the fragrance remaining property cannot be easily recognized. When the content of the component (A) exceeds 5 mass%, the preservation stability may decrease under high temperature conditions.

[0019] [Component (B)] The component (B) contained in the liquid treatment composition for textile products according to the invention is a glucan comprising an inner branched cyclic structure portion and an outer branched structure portion and having a degree of polymerization of 50 to 10,000, the inner branched cyclic structure portion being a cyclic structure portion formed from a-1,4-glucoside bond and a-1,6-glucoside bond, and the outer branched structure portion being a non-cyclic structure portion attached to the inner branched cyclic structure portion. The glucan as mentioned above is generally called highly branched cyclic dextrin or cluster dextrin, and also hereinafter referred to as "highly branched cyclic dextrin." The highly branched cyclic dextrin that is contained in the liquid treatment composition for textile products according to the invention has a molecular weight of about 30,000 to about 1,000,000, and comprises predominantly a dextrin with a weight average degree of polymerization of about 2,500, having one cyclic structure in the molecule thereof and a number of glucan chains bonded to the cyclic structure.

The inner branched cyclic structure portion of the highly branched cyclic dextrin that is contained in the liquid treatment composition for textile products according to the invention is composed of about 10 to 100 glucose units. A number of non-cyclic branched glucan chains are bonded to the inner branched cyclic structure portion.

[0020] By way of example, the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention may have a degree of polymerization of 50 to 5,000.

By way of example, the inner branched cyclic structure portion of the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention may have a degree of polymerization of 10 to 100. By way of example, the external branched structure portion of the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention may have a degree of polymerization of 40 or more.

By way of example, in the external branched structure portion of the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention, each unit chain may have a degree of polymerization of 10 to 20 on average.

[0021] The highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention may be prepared, for example, by allowing a starch as the raw material to react with an enzyme, i.e., a branching enzyme. The starch as the raw material comprises amylose having a linear chain structure made up of glycose units linked by a-1,4-glycosidic bond; and amylopectin having a highly branched structure by a-1,6-glycosidic bond. The amylopectin is a macromolecule made up of a great number of cluster structures. The branching enzyme used is a glucan chain transferase widely distributed in plants, animals and microorganisms, which acts on the bonds of cluster structures of amylopectin and catalyzes the cyclization reaction thereof More particularly, the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention is a glucan comprising an inner branched cyclic structure portion and an outer branched structure portion and having a degree of polymerization of 50 to 10,000, as described in JP H8-134104 A. The term "highly branched cyclic dextrin" herein used can be understood in consideration of the description of JP H8-134104 A. [0022] Unlike the general cyclodextrin having 6 to 8 glucose units linked, such as a-cyclodextrin (n=6), f3-cyclodextrin (n=7), y-cyclodextrin (n=8) or the like, the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention has the particular structure as mentioned above, and shows a higher degree of polymerization (i.e., larger molecular weight).

As a specific example of the highly branched cyclic dextrin contained in the liquid treatment composition for textile products according to the invention, a commercially available product "Cluster Dextrin (registered trademark)" made by Glico Nutrition Co., Ltd., can be used.

Even if the general cyclodextrin having 6 to 8 glucose units linked, such as ct-cyclodextrin (n=6), f3-cyclodextrin (n=7), y-cyclodextrin (n=8) or the like is contained instead of the highly branched cyclic dextrin in the liquid treatment composition for textile products, it is impossible to obtain the same excellent effects of inhibiting a change of fragrance tone and improving the fragrance remaining property as those provided by the liquid treatment composition for textile products according to the invention.

[0023] In the liquid treatment composition for textile products according to the invention, the content of the component (B) is not particularly limited, but may preferably be in the range of 0.01 to 10 mass%, more preferably 0.03 to 5 mass%, and further more preferably 0.05 to 3 mass%, based on the total mass of the composition when the composition is used as a softener composition. The component (B) contained in an amount of over 0.01 mass% can exhibit excellent effects of inhibiting a change of fragrance tone and improving the fragrance remaining property. When the component (B) is contained in an amount of more than 10 mass%, the effects of inhibiting a change of fragrance tone and improving the fragrance remaining property cannot be further enhanced, and in addition, the stability may degrade and the handling properties may decrease due to the increased viscosity of the liquid composition during the storage at high temperatures. The content of the component (B) may preferably be in the range of 0.01 to 5 mass%, more preferably 0.03 to 3 mass%, and further more preferably 0.05 to 1 mass%, based on the total mass of the composition when the composition is used as a spray type fabric treatment composition. The component (B) contained in an amount of over 0.01 mass% can produce excellent effects of inhibiting a change of fragrance tone and improving the fragrance remaining property. When the component (B) is contained in an amount of more than 10 mass%, the stability may degrade and the handling properties may decrease due to the increased viscosity of the liquid composition during the storage at high temperatures.

The ratio by mass of the component (A) to the component (B) in the liquid treatment composition for textile products according to the invention is not particularly limited, but may preferably be in the range of 1/100 to 20, more preferably 1/10 to 5, and further more preferably 1/5 to 1 when the composition is used as a softener composition and a spray type fabric treatment composition.

[0024] When the smell of a liquid treatment composition for textile products is compared with the smell of a cloth treated with the treatment composition, a change of fragrance tone is recognized, in particular the tone of fragrance resulting from the perfume ingredients with low ClogP values. The reason for this has not been definitely clarified, but the following reason can be given: When the composition is prepared as a softener composition, it is considered that the perfume ingredients with low ClogP values (hydrophilic perfume ingredients) cannot be easily incorporated into vesicles formed by a cationic surfactant, and thus tend to exist in a bulk. Therefore, the perfume ingredients with low ClogP values readily discharge together with rinsing water during the softening treatment of washing cycles, so that those perfume ingredients are not easily adsorbed by cloths. As the result, the proportion of the perfume ingredients with low ClogP values will be smaller on the cloth treated with a softener composition than that of the perfume ingredients in the softener composition, thereby the fragrance tone is recognized to be different from the fragrance tone of the softener composition.

When the composition is prepared as a spray type fabric treatment composition, it is considered that the perfume ingredients with low ClogP values cannot be easily incorporated into micelles formed by a cationic surfactant, and thus tend to exist in a bulk. Therefore, when the treatment composition is sprayed onto a cloth, the perfume ingredients with low ClogP values are attached to the cloth without being enclosed in the micelles, so that those perfume ingredients readily vaporize from the cloth. As the result, the proportion of the perfume ingredients with low ClogP values will be smaller than that in the spray type fabric treatment composition, thereby the fragrance not is recognized to be changed.

[0025] As previously explained, the perfume ingredients with low ClogP values have a tendency of being present in a bulk without being incorporated into the cationic surfactant in both cases of the softener composition and the spray type fabric treatment composition, so that those perfume ingredients cannot easily stay on cloths.

The liquid treatment composition for textile products according to the invention comprises the highly branched cyclic dextrin, which establishes a spiral structure when dissolved in the bulk. The perfume can be included in the spiral structure of the highly branched cyclic dextrin, and the resultant inclusion compound is considered to be adsorbed on cloths. The highly branched cyclic dextrin does not maintain the spiral structure on the fibers of cloth, so that the perfume is extendedly released from the inclusion compound adsorbed on cloths. It is therefore considered that the fragrance of the perfume ingredients with low ClogP values can be sufficiently smelled and a change of fragrance tone can be inhibited.

Further, the perfume ingredients having a cyclic structure therein are supposed to exhibit more noticeable effects because those perfume ingredients are considered to readily cause an interaction with the highly branched cyclic dextrin.

[0026] [Component (C)] The component (C) contained in the liquid treatment composition for textile products according to the invention is a cationic surfactant. For example, the cationic surfactant used as the component (C) in the invention is at least one compound selected from the group consisting of amine compounds having in the molecule thereof one to three hydrocarbon groups with 10 to 26 carbon atoms (which may be hereinafter referred to as "long-chain hydrocarbon groups") which may be separated by an ester group or an amide group, and salts and quaternary compounds of the above-mentioned amine compounds. In particular, it is preferable to use acid salts of a tertiary amine having in the molecule thereof at least one hydrocarbon group which has 10 to 26 carbon atoms in total and may be separated by an ester group or an amide group, or the quaternary compounds thereof When the liquid treatment composition for textile products according to the invention is used as a softener composition, the component (C) may preferably be at least one compound selected from the group consisting of amine compounds having in the molecule thereof one to three hydrocarbon groups with 10 to 26 carbon atoms, which may be separated by an ester group or an amide group, and salts and quaternary compounds of the above-mentioned amine compounds. Particularly, the long-chain hydrocarbon group may have 10 to 26 carbon atoms, preferably 17 to 26 carbon atoms, and more preferably 19 to 24 carbon atoms. The long-chain hydrocarbon group having 10 or more carbon atoms will lead to excellent softness; and the long-chain hydrocarbon group having 26 or less carbon atoms will provide excellent handling properties.

When the liquid treatment composition for textile products according to the invention is used as a spray type fabric treatment composition, the component (C) may preferably be at least one compound selected from the group consisting of amine compounds having in the molecule thereof two hydrocarbon groups with 10 to 14 carbon atoms, which may be separated by an ester group or an amide group, and salts and quaternary compounds of the above-mentioned amine compounds; and amine compounds having in the molecule thereof one hydrocarbon group with 10 to 18 carbon atoms, which may be separated by an ester group or an amide group, and salts and quaternary compounds of the above-mentioned amine compounds. In particular, the amine compounds having in the molecule thereof two hydrocarbon groups with 10 to 14 carbon atoms, which may be separated by an ester group or an amide group, and salts and quaternary compounds of the above-mentioned amine compounds are especially preferable.

[0027] The long-chain hydrocarbon group may be saturated or unsaturated. In the 25 unsaturated long-chain hydrocarbon group, the double bond may be arranged anywhere. When there is one double bond, the double bond may preferably be located at the center of the long-chain hydrocarbon group, or distributed about the median.

The long-chain hydrocarbon group may be a chain hydrocarbon group or a hydrocarbon group having a ring in the structure thereof The chain hydrocarbon group is preferred. The chain hydrocarbon group may be a straight-chain or branched hydrocarbon group. In particular, an alkyl group or alkenyl group is preferable as the chain hydrocarbon group, and the former is more preferable.

The long-chain hydrocarbon group may be separated by an ester group (-COO-) or an amide group (-NHCO-). In other words, the long-chain hydrocarbon group may comprise in the carbon chain thereof at least one separating group selected from the group consisting of an ester group and an amide group, and the carbon chain may be separated by the separating group. The presence of the separating group is advantageous because the biodegradability of the resultant product will become higher. [0028] When the above-mentioned separating group is present, one long-chain hydrocarbon group may have one separating group or two or more separating groups. Namely, the long-chain hydrocarbon group may be separated at one location or two or more locations. When there are two or more separating groups, those separating groups may be the same or different.

When the separating group exists in the carbon chain, the number of carbon atoms contained in the separating group is included in the total number of carbon atoms of the long-chain hydrocarbon group.

[0061] [Method for preparing softener compositions] The predetermined amount of each component was weighed in accordance with the formulations as shown in the following Tables 2 and 3, and then liquid softener compositions were prepared according to the following procedures.

Using a glass vessel with an inner diameter of 100 mm and a height of 150 mm and an agitator (Agitor Model SJ, made by Shimadzu Corporation), liquid softener compositions were prepared in accordance with the procedures shown below. First, the component (A), the component (C) and the adduct of primary isotridecyl alcohol with 60 moles of ethylene oxide (which is an optional component) were mixed with stirring to obtain an oil phase mixture. The component (B) and the isothiazolone solution (which is an optional component) were dissolved in deionized water used as the balance of each composition to obtain an aqueous phase mixture. The mass of the above-mentioned deionized water corresponds to the difference obtained by subtracting the total amounts of the oil phase mixture and the component (B) from 980 g. The oil phase mixture heated to a temperature equal to or higher than the melting point of the component (C) was placed into the glass vessel, followed by stirring, and the aqueous phase mixture heated to a temperature equal to or higher than the melting point of the component (C) was added to the oil phase mixture in two divided portions with stirring, followed by further stirring. The ratio by mass of the divided portions of the aqueous phase mixture was 30:70. The stirring was conducted at 1,000 rpm for three minutes after addition of the first portion of the aqueous phase mixture, and for two minutes after addition of the second portion of the aqueous phase mixture. Thereafter, calcium chloride (which is an optional component) was added to the mixture, and hydrochloric acid (1 mol/L, reagent made by Kanto Chemical Co., Inc.) or sodium hydroxide (1 mol/L, reagent made by Kanto Chemical Co., Inc.) was appropriately added when necessary to adjust the pH to 2.5. Finally, deionized water was added until the total mass reached 1,000 g, thereby obtaining desired liquid softener compositions.

[0062] [Method for preparing spray type fabric treatment compositions] The predetermined amount of each component was weighed in accordance with the formulations as shown in the following Tables 4 and 5, and then liquid softener compositions were prepared according to the following procedures.

The score of A or more was regarded as acceptable in light of the commercial value.

The treatment was conducted as follows using the twin-tub washing machine (Model VH-30S, made by Toshiba Corporation). The knitted cotton cloth was washed with a commercially available laundry detergent TOP Platinum Clear (made by Lion Corporation) for 10 minutes (a standard use level; a standard course; a bath ratio of 20 times; and tap water of 25°C), and then the first rinsing operation for 3 minutes was conducted and the second rinsing operation for 3 minutes using each softener composition was conducted (with respect to 1.5 kg of knitted cotton cloth; 10 mL of softener composition; a bath ratio of 20 times; and tap water of 25°C). A spin-dry operation for one minute was interposed between each of the washing operation and the first rinsing step and the second rinsing operations. After the treatment, the pieces of cloth were dried for 20 hours under thermostatically and humidstatically controlled conditions (20°C and 45%RH).

[0065] 3. Treatment by spraying operation Each spray type fabric treatment composition prepared as mentioned above was filled into a trigger-type bottle and sprayed on the knitted cotton cloth.
