Description of embodiments of the invention

[0010] <Composition of the processing agent for textiles>

The present inventors have found that a textile processing agent composition that is capable of imparting texture to textiles can be obtained by combining an internal olefin sulfonate having 16 or more and 24 or less carbon atoms and a textile softener base, for example, an organosilicon compound or clay mineral. Texture in the present invention means a feeling at the time of touching a textile article with a hand or skin, such as softness, a feeling of fluffiness or smoothness.

[0011] [Component (A)]

Component (A) in the present invention is an internal olefinsulfonate having 16 or more and 24 or less carbon atoms. When component (A) is used in combination with a textile softener base as component (B), for example, an organosilicon compound or a clay mineral, the effect of component (B) in imparting texture to textiles is further enhanced.

[0012] In terms of enhancing the effect of component (B) in imparting texture to textiles, the number of carbon atoms in the internal olefinsulfonate in component (A) is preferably 16 or more, preferably 17 or more, more preferably 18 or more, and 24 or less, preferably 22 or less, more preferably 20 or less, even more preferably 19 or less. This carbon number is the number of carbon atoms in the sulfonic acid moiety of the internal olefin that does not include the salt moiety in component (A). The textile treatment composition of the present invention preferably contains, as component (A), an internal olefin sulfonate having 17 or more and 24 or less carbon atoms.

[0013] From the standpoint of enhancing the action of the textile softener base as component (B) in imparting texture to textiles, for example, an organosilicon compound or a clay mineral, and in particular ensuring that a smooth texture can be imparted to textiles, the proportion an internal olefinsulfonate having 17 or more and 24 or less carbon atoms in the component (A) contained in the composition of the processing agent for textiles according to the present invention is preferably 10 mass% or more, more preferably 30 mass% or more, even more preferably 50 wt.% or more, further preferably 60 wt.% or more, even more preferably 70 wt.% or more, even more preferably 75 wt.% or more, even more preferably 80 wt.% or more, still more preferably 85 wt.% or more, even more preferably 90 wt.% or more, even more preferably 95 wt.% or more, most preferably 100 wt.%.

[0014] From the standpoint of enhancing the effect of the textile softener base as component (B) in imparting texture to textiles, for example, an organosilicon compound or a clay mineral, and in particular, imparting a smooth texture to textiles, the mass ratio of the content of an internal olefin sulfonate having 16 carbon atoms (A _C16 ), to the content of an internal olefinsulfonate having 17 or more and 24 or less carbon atoms (A _C17-C24 ), (A _C16 )/(A _C17-C24 ), in component (A) contained in composition of the processing agent for textiles according to the present invention is preferably 10 or less, more preferably 5 or less, further preferably 3 or less, even more preferably 1 or less, even more preferably 0.8 or less, even more preferably 0.7 or less, even more preferably 0.6 or less, even more preferably 0.5 or less, even more preferably 0.4 or less, still more more preferably 0.3 or less, even more preferably 0.2 or less, even more preferably 0.1 or less, and preferably 0 or more, and most preferably 0.

[0015] The internal olefin sulfonates in component (A) include those derivatives which contain a very small amount of so-called alpha-olefin sulfonates (hereinafter also referred to as α-olefin sulfonates) in which the double bond is present at position 1 of the carbon chain. Component (A) may contain alpha-olefinsulfonate in an amount of up to 10 wt.%. In order to ensure that the texturizing effect of textiles can be maintained even when the composition of the processing agent for textiles is used for low temperature processing, the content of alpha-olefin sulfonate is preferably 7 mass% or less, more preferably 5 mass% or less. , further preferably 3 wt.% or less, and for reasons of reducing manufacturing costs and improving productivity, the content of alpha-olefinsulfonate is preferably 0.01 wt.% or more.

[0016] When an internal olefin undergoes sulfonation, β-sultone is quantitatively formed, and β-sultone is partially converted to γ-sultone and olefin sulfonic acid, which are further converted to hydroxyalkane sulfonate and olefin sulfonate in the neutralization and hydrolysis steps (for example, in J. Am. Oil Chem. Soc., Vol. 69, p. 39 (1992)). Here, the hydroxy group of the formed hydroxyalkane sulfonate is present inside the alkane chain, and the double bond of the olefin sulfonate is inside the olefin chain. The products obtained are mainly mixtures of these sulfonates, some of which may contain a very small amount of hydroxyalkane sulfonate having a hydroxy group at the end of the carbon chain, or olefin sulfonate having double bonds at the end of the carbon chain.

[0017] Here, the products and mixtures thereof are collectively referred to as internal olefin sulfonate (component (A)). The hydroxyalkane sulfonate is referred to as the hydroxy form of internal olefin sulfonate (here also referred to as HAS), and the olefin sulfonate is referred to as the olefin form of internal olefin sulfonate (here also referred to as IOS).

The mass ratio of compounds in component (A) can be measured by high performance liquid chromatography-mass spectrometry (hereinafter, abbreviated as HPLC-MS). More specifically, the weight ratio can be determined from the area of the peaks in the HPLC-MS chromatograms for component (A).

[0018] Examples of salts in the internal olefin sulfonate include alkali metal salts, alkaline earth metal salts (1/2 atom), ammonium salts, and ammonium salts with organic radicals. Examples of alkali metal salts include sodium salts and potassium salts. Examples of ammonium salts with organic radicals include alkanolammonium salts having 1 or more and 6 or less carbon atoms.

[0019] For reasons of further enhancing the effect of a textile softener base as component (B) in imparting texture to textiles, for example, an organosilicon compound or a clay mineral, component (A) in the present invention is an internal olefin sulfonate having 16 or more and 24 or less carbon atoms, and in the internal olefin sulfonate, the mass ratio of the internal olefin sulfonate having the sulfonate group at position 2 or above and 4 or below, and having 16 or more and 24 or less carbon atoms (IO-1S), to the internal olefin sulfonate having the sulfonate group at position 5 or higher, and having 16 or more and 24 or less carbon atoms (IO-2S), (IO-1S)/(IO-2S), preferably 0.65 or more, more preferably 0.75 or more, more preferably 0.9 or more, further preferably 1.0 or more, even more preferably 1.2 or more, even more preferably 1.4 or more, even more preferably 1.6 or more, even more preferably 2.0 or more, even more preferably 2.4 or more, even more preferably 4.5 or more, and preferably 5.5 or less.

[0020] The levels of compounds differing in the position of the sulfonate group in component (A) can be measured by HPLC-MS. The content levels of compounds differing in the position of the sulfonate group are here defined as a mass ratio based on the areas of the HPLC-MS peaks for compounds having sulfonate groups in the corresponding positions in all HAS in component (A).

Here, HAS refers to hydroxyalkane sulfonates among the compounds formed by the sulfonation of sulfonic acids of internal olefins, that is, the hydroxy forms of internal olefin sulfonates.

In the present invention, an internal olefin sulfonate having a sulfonate group at position 2 or above and 4 or below and having 16 or more and 24 or less carbon atoms (IO-1S) means a sulfonate having a sulfonate group at position 2 or above and 4 or below, and having 16 or more and 24 or less carbon atoms, in the HAS form having 16 or more and 24 or less carbon atoms.

An internal olefin sulfonate having a sulfonate group at position 5 or higher and having 16 or more and 24 or less carbon atoms (IO-2S) means a sulfonate having a sulfonate group at position 5 or higher and having 16 or more and 24 or less carbon atoms, in the HAS form having 16 or more and 24 or less carbon atoms.

[0021] The internal olefin sulfonate which is component (A) is composed by including an internal olefin sulfonate having a sulfonate group at position 2 or above and 4 or below, and having 16 or more and 24 or less carbon atoms (IO-1S), and an internal olefinsulfonate having a sulfonate group at position 5 or higher and having 16 or more and 24 or less carbon atoms (IO-2S). The maximum value of the binding position of the sulfonate group in the internal olefinsulfonate (IO-2S) varies depending on the number of carbon atoms.

[0022] The mass ratio (IO-1S)/(IO-2S) for the component (A) is given by the component (A) that is ultimately obtained. For example, even an internal olefin sulfonate obtained by mixing an internal olefin sulfonate in which the mass ratio of (IO-1S)/(IO-2S) is outside the above range is considered an internal olefin sulfonate of component (A) when the mass ratio of (IO-1S)/( IO-2S) in the internal olefin sulfonate is within the above range.

[0023] With regard to the mass of the above-mentioned component (A), sulfonate (IO-1S) or sulfonate (IO-2S), a value calculated based on the form of sodium ions instead of counterions is used.

[0024] <Component (B)>

Component (B) is a softener base for textiles. Textile softener base means a compound that assists in softening a textile when added to a textile in an amount of 0.1 parts by weight based on 100 parts by weight of the textile.

[0026] The clay mineral is also a swelling inorganic compound.

Even when a clay mineral having a low bulk relative swelling ratio is used, a textile softness effect comparable to that of a clay mineral having a high bulk bulk swelling ratio can be obtained by using the component (A) in the present invention in combination.

[0027] The relative volumetric swelling of the clay mineral is the relative volumetric swelling determined according to the following expression (1):

Expression (1): relative volume swelling (%)=(L1/L2)×100

where L1 represents the volume 24 hours after the addition of 0.5 g of the clay mineral to an aqueous solution of 1000 mg/kg (25°C) sodium laurylbenzenesulfonate, and

L2 represents the apparent volume of 0.5 g of clay mineral in air.

[0028] More specifically, the relative volumetric swelling may be calculated by the method in the Examples according to the Japan Bentonite Association Standard Test Method "Swelling Test Method on Bentonite (powder)". )") (JBAS-104-77). Those skilled in the art will be able to easily understand and execute the relative bulk swelling test method.

By using the clay mineral in combination with the component (A) in the present invention, a soft texture can be imparted to textiles even when the clay mineral has a low relative volume swelling, for example, from 100% to 150%. By using a clay mineral in combination with component (A), in the present invention, a clay mineral having relative volume swelling values in a wide range, such as a range of 100% to 900%, can be selected and used.

[Method of measuring the relative volumetric swelling of the clay mineral as a component (B)]

The relative volumetric swelling capacity of the clay mineral as component (B), that is, each of (b-1), (b-2) and (b-3), was calculated by the following method.

50 ml of an aqueous solution of sodium laurylbenzenesulfonate at a concentration of 1000 mg/kg was placed in a stoppered 50 ml colorimetric tube (IWAKI COLOR-TUBE50S). The temperature of the aqueous solution of sodium laurylbenzenesulfonate was 25°C. Then, 0.5 g of the clay mineral was placed in 10 parts in a glass tube so that the clay mineral did not stick to the wall surface of the glass tube. After the clay mineral was allowed to stand within the temperature range of 25°C±0.5°C for 24 hours, the deposited material height (L1h, mm) was measured. Separately, 0.5 g of the clay mineral alone was placed in 10 parts in a 50 ml heat-resistant glass tube so that the clay mineral did not adhere to the wall surface of the glass tube. After the clay mineral was allowed to stand within the temperature range of 25°C±0.5°C for 24 hours, the deposited material height (L2h, mm) was measured. Since the area inside the bottom surface of the glass tube is constant, the relative volumetric swelling can be calculated from the height value. That is, the value calculated from the expression (1') below is equal to the relative bulk swelling capacity (%) from the above expression (1).

Expression (1'): relative volumetric swelling (%)=(L1h/L2h)×100

As sodium laurylbenzenesulfonate, NEOPELEX G-15 (manufactured by Kao Corporation) was used. Water purified by ion exchange was used as water.

[0153] <Obtaining the composition of the processing agent for textiles>

The compositions of the processing agent for textiles, as shown in Tables 1-3, were obtained using the above composite components and purified ion exchange water, and the evaluation was carried out according to the following indicators. The results are shown in Tables 1-3.

More specifically, the compositions of the processing agent for textiles, as shown in Table 1, were obtained as follows. A stir bar 5 cm long coated with Teflon (Teflon, registered trademark) was placed in a 200 ml glass beaker, and the weight of the beaker was measured. Then, 80 g of purified ion-exchanged water at 20° C., component (A) or component (A') and component (B) were placed in the beaker, and the beaker was covered on the top side with Saran Wrap (registered trademark) soft film.

The beaker containing the contents was placed in a water bath placed on a magnetic stirrer and kept at a temperature of 60°C, and the contents were stirred at 100 rpm for 30 minutes within a temperature range of 60°C±2°C as measured by the temperature of the water in the water bath. The water in the water bath was then changed to 5° C. tap water and the beaker was cooled to 20° C. as measured by the temperature of the composition in the beaker. The Saran Wrap (registered trademark) film was then removed and the pH value at 20°C of the textile treatment composition was adjusted to 7.5 using 0.1N. an aqueous solution of sodium hydroxide or 0.1N. aqueous solution of hydrochloric acid. Then, ion-exchanged water was added so that the contents had a mass of 100 g, and stirring was again carried out at 100 rpm for 30 minutes to obtain each of the textile treatment agent compositions as shown in Table 1. products in tables 2 and 3 were obtained in a similar way. In tables 1-3, the weight ratio (A)/(B) is shown with component (A') used instead of component (A).

(1) Obtaining the model artificial sebum-stained tissue

A model sebum-stained tissue was obtained by applying a model sebum-stained liquid with the following composition to the fabric. The application of the simulated artificial sebum stained liquid to the fabric was carried out by printing the artificial staining liquid onto the fabric using a corrugated roller coater. The method of obtaining a model artificially sebum-stained tissue by applying a model artificially sebum-stained liquid onto the fabric was performed using a corrugated roller with a cavity capacity of 58 cm ³ /m ² , with an application speed of 1.0 m/min, at a drying temperature of 100°C and a duration drying for 1 minute. Cotton 2003 (manufactured by Tanigashira Shoten KK) was used as the fabric. *Composition of the model artificial sebum-stained liquid: lauric acid: 0.4 wt.%, myristic acid: 3.1 wt.%, pentadecanoic acid: 2.3 wt.%, palmitic acid: 6.2 wt.%, heptadecanoic acid: 0.4 wt.%, stearic acid: 1.6 wt.%, oleic acid: 7.8 wt.%, trioleic acid: 13.0 wt.%, n-hexadecyl palmitate: 2.2 wt.%, squalene: 6.5 wt.%, liquid crystalline component of egg white lecithin: 1.9 wt.%, reddish soil "Kanuma": 8.1 wt.%, soot: 0.04 wt.%, and water: the rest of the amount ( in general: 100% by weight.

[0161]

(2) Detergency rating

Five simulated sebum-stained tissues (6 cm×6 cm) prepared as described above were cleaned at 85 rpm for 10 minutes using a cleaning properties analyzer (tergotometer) (Ueshima, MS-8212). The fabrics were cleaned in each case under the following conditions: tap water (hardness 3.5°dH, 20°C) was supplied so that the concentration of the textile treatment agent composition as shown in Table 1 was 0.033 mass%, and the cleaning was performed at a water temperature of 20°C. After cleaning, the fabric was rinsed with tap water (20° C.) for 3 minutes. Thereafter, the soiled fabric after rinsing was subjected to a dehydrating treatment for 1 minute using a double drum washing machine, and then left to dry at 20° C. and 43% relative humidity (RH) for 12 hours. The degree of stain removal was assessed by visual inspection. It was confirmed that all the compositions of the treating agent for textiles as shown in Table 1 had washing power because the model sebum-stained fabric after cleaning was less soiled than the fabric before cleaning. In addition, the washing power was evaluated in the same manner as in the washing power evaluation in Table 1, except that the washing liquids were adjusted so that the concentration of each of the textile treatment agent compositions as shown in Table 2 was 0 08 wt.%, and the concentration of each of the compositions of the processing agent for textiles, as shown in Table 3, was 0.11 wt.%. It was confirmed that all the compositions of the treating agent for textiles, as shown in Tables 2 and 3, had washing power, since the model artificial sebum-stained fabric after cleaning was less contaminated than the fabric before cleaning.
