Liquid softener composition Technical field

 The present invention relates to a liquid softener for use in textiles such as clothing. In particular, the present invention is to impart excellent flexibility, smoothness, drapability and quick-drying to various fiber products and clothing made of not only natural fibers such as cotton but also synthetic fibers such as polyester. The present invention relates to a liquid softener composition mainly composed of silicone, which can be used and is mild on the skin. Background art

 Conventionally, various softeners containing a quaternary ammonium salt as a main component have been used for the purpose of imparting flexibility to textiles, which is added during rinsing after washing. As the quaternary ammonium salt, a di-long chain type quaternary ammonium salt is generally used. However, softeners containing di-long chain quaternary ammonium salt as a main component can provide a good softening effect for cotton products, but can give a slimy feeling or, depending on the conditions, can be used for polyesters and the like. The softening effect on chemical fiber products is small, and the effect of imparting smoothness and drape to various fiber products is also small. In addition, softeners using di-long chain type cationic surfactants are generally emulsion-based, but attempts have been made to obtain highly transparent compositions in order to increase their commercial value. No. 5,590,066). However, since the di-long chain type cationic surfactant is poorly soluble in water, a large amount of an organic solvent must coexist in order to obtain a transparent composition. For this reason, it is uneconomical to mix a large amount of an organic solvent which has an unpleasant organic solvent smell and has no effect of imparting flexibility.

On the other hand, silicone compounds are known to impart unique flexibility, suppleness and smoothness to textile products, especially chemical fibers. However, silicone has poor adsorbability to fibers when finished in a water bath, and must be treated from a highly concentrated bath to obtain a sufficient effect. In order to remedy such a drawback, the present inventors have proposed that a silicone be water-bathed as described in JP-A-2000-154476. As a means of efficiently adsorbing fibers from inside, we proposed a fashionable finish composition using a combination with a small amount of cationic surfactant. However, this finishing composition exhibits excellent performance when used after a nonionic detergent used for fashion, but remains in the rinse bath when used after an anionic detergent used for ordinary laundry. There was a problem that the performance was lowered due to the susceptibility of the anion activator.

 Also, Japanese Patent Application Laid-Open No. H10-183472 discloses a finish for clothing containing a water-insoluble and non-curable silicone mainly composed of a water-soluble polymer compound conventionally used for giving a firmness to clothing. An agent composition is disclosed. Further, JP-A-2000-129577 and JP-A-2000-129578 disclose a water-soluble polymer compound which has been conventionally used for imparting firmness to clothing, a silicone compound and a non-ion compound. Disclosed is a treating agent composition for textiles, which comprises a hydrophilic surfactant. However, treating textiles with these compositions increases the stiffness value and is not preferred as a softener for flexibility.

 Further, Japanese Patent Application Laid-Open No. 2000-239970 proposes a textile product treating agent mainly composed of a water-soluble polymer compound conventionally used for imparting elasticity to clothing and containing an amino-modified silicone. I have. However, when a fiber product is treated with this composition, not only is it not preferable as a softening agent because the rigidity is increased, but also the fiber product may be yellowed by the amino-modified silicone depending on storage conditions and the like. Disclosure of the invention

The present invention is capable of imparting excellent flexibility, smoothness, drapability, and quick-drying property, is mild on the skin, has good storage stability, and has an added value to the appearance of the product. An object of the present invention is to provide a water-based liquid softener composition having a highly transparent liquid appearance and good water absorption. The liquid softener composition can be used not only for nonionic detergents such as fashionable ones but also for finishing treatment in a rinsing bath after washing with a general-purpose anion detergent. It is intended to be applicable to various textile products such as clothing made of chemical fibers such as polyester as well as polyester fibers.

 The inventor of the present invention uses a silicone compound and a cationic polymer compound in a specific ratio to impart excellent flexibility, smoothness, drape and quick-drying to the skin while being mild. In addition, storage stability is improved by using a nonionic surfactant and a water-soluble solvent in combination, and by using a silicone compound having a polyether group as a silicone compound, water absorption is excellent and transparency is high. A liquid softener having a liquid appearance was obtained, and it was found that the above-mentioned objects could be achieved by these. Thus, the present invention was completed.

The component (A) of the present invention is a silicone compound. This silicone compound is not particularly limited as long as it can impart flexibility, smoothness, and drapability when adsorbed on a fiber product. Silicone compounds generally used for fiber treatment include dimethyl silicone, polyether-modified silicone, methylphenyl silicone, alkyl-modified silicone, higher fatty acid-modified silicone, and methyl methacrylate. Examples include idrogen silicone, fluorine-modified silicone, epoxy-modified silicone, epoxy-modified silicone, carbinol-modified silicone, and amino-modified silicone.One of these may be used alone or as a mixture of two or more. be able to.

 The molecular structure of the silicone compound may be linear, branched or cross-linked. The modified silicone compound may be modified with one kind of organic functional group, or may be modified with two or more kinds of organic functional groups.

 The silicone compound can be used as an oil or as an emulsified product dispersed with an optional emulsifier. In particular, a silicone compound containing no amino group is preferable from the viewpoint of preventing yellowing of a softened textile product. Furthermore, the silicone compound of component (A) is nonionic because it enhances the effect of component (B) to be described later to adsorb the silicone compound of component (A) to the fiber and enhances flexibility, smoothness, and drapability. And more preferred examples include dimethyl silicone, carbinol-modified silicone, epoxy-modified silicone, and polyether-modified silicone.

Among these, a particularly preferred silicone compound is a polyether-modified silicone from the viewpoints of flexibility, water absorption, transparency of the liquid softener composition and enhancement of commercial value. Compared to dimethyl silicone that does not have a polyester group, this silicone has less tingling and has good flexibility, and also has good water absorption for natural fibers such as cotton and synthetic fibers such as polyester. It is suitable for obtaining a transparent liquid softener composition. Preferred polyether-modified silicones include copolymers of alkyl (1 to 3 carbon atoms) siloxane and polyoxyalkylene (preferably 2 to 5 carbon atoms in the alkylene group). Of these, a copolymer of dimethylsiloxane and polyoxyalkylene is preferred. In addition, polyoxyalkylene refers to polyoxyethylene, polyoxypropylene, or a random or block polymer of polyoxethylene and polyoxypropylene. Examples of such a compound include a compound represented by the following general formula (I).

(Wherein, M, N, a and b are average degrees of polymerization, and R represents hydrogen or an alkyl group, where M is 10 to: L0000, N is 1 to; L0000. And M> N, and M is preferably 10 to: L0000, N is 1 to 50, and more preferably M> N, a is 2 to 100, and b is R is preferably 0 to 50. R is preferably hydrogen or an alkyl group having 1 to 4 carbon atoms.

 From the viewpoint of mildness, it is preferable that M + N is larger within the above range. Further, it is preferable that low-molecular-weight compounds such as unreacted substances which are unavoidably mixed in during the production are removed by a purification step such as stripping as much as possible.

 The compound represented by the above general formula (I) generally has a methyl-hydrogen polysiloxane having a Si—H group and a carbon-carbon double bond such as a polyoxyalkylene aryl ether. It can be produced by an addition reaction with a polyoxyalkylene alkyl ether having a terminal.

Methylhydrogenpolysiloxane can be produced by the following conventional method. As a specific production method, first, methylchlorosilanes are obtained by a direct method in which metal silicon and methyl chloride are heated in the presence of a copper catalyst. Next, dimethyldichlorosilane (boiling point 70.2 ° C), trimethylchlorosilane (boiling point 57.3), and methyl hydrogendichlorosilane (boiling point 40.4) fractionated from the methylchlorosilanes were removed. The mixture is mixed at a predetermined ratio and hydrolyzed by adding a large amount of water to obtain a mixture of cyclic and linear dimethylsiloxane and methylhydrogensiloxane copolymer. Further, the obtained mixture of cyclic and linear dimethyl siloxane and methyl hydrogen siloxane copolymer is separated into low-polymerized cyclic (tetramer and pentamer) by distillation to obtain an organohydrogen. Used for the polymerization of genpolysiloxane. The organohydrogenpolysiloxane is prepared by heating a cyclic compound with a low degree of polymerization using an alkali or strong acid as a catalyst to cleave the siloxane bond and re-open it. It can be obtained by a polymerization reaction containing a bond. The polymerization of the ring by an alkaline catalyst is carried out at a high temperature of about 150 ° C using an alkali metal hydroxide as a catalyst, but lithium hydroxide and sodium hydroxide dissolve in the ring with a low degree of polymerization even at this temperature. Without this, it is not preferable because the cyclic body cannot be polymerized. Further, the polymerization of a cyclic body by an acid catalyst can be carried out at room temperature or by heating with sulfuric acid, hydrochloric acid, phosphoric acid, activated clay, iron chloride, boric acid, trifluoroacetic acid or the like as a catalyst. However, in the case of dimethylpolysiloxane, it can be polymerized with either an acid or a base. However, in the case of an organohydrogenpolysiloxane having a Si_H group, if a basic catalyst is used, the polymerization of the Si—H Is not preferable because it decomposes and gels. The polymerization of such methylhydrogenpolysiloxane is terminated by neutralizing the catalyst, and then the by-product cyclic substance is removed by stripping, thereby completing the production of the target methylhydrogenpolysiloxane. .

Specific examples of the polyether-modified silicone oil used in the present invention include SH3772M, SH3775M, SH3748, SH3749, SF8410, SH8700, BY22-008, and SF8421 manufactured by Toray Dow Corning Silicone Co., Ltd. , KF 352A, KF 6008, KF 615A, KF 6016, KF 6017, Shin-Etsu Chemical Co., Ltd., TSF4 450, TSF4452, GE Toshiba Silicone Co., Ltd., SI LWET L- 7001, SI LWET L—7002, SI LWET L—7602, SI LWET L-7604> SI LWET FZ-2104, SI LWET F Z-2120, SI LWET FZ_2161, SI LWET FZ-2162, SI LWE TFZ—2164, SI LWETF Z— 2171, ABN SI LWET F ZF 1-009-01 ABN SI LWET FZ-F 1— 009-02, ABN SI LWET FZ— F 1— 009-03, AB NSI LWET FZ— F 1— 009— 05 , ABN SI LWET FZ—F 1—009—09, ABN SI LWET FZ-F 1-009-11, ABN SI LWET FZ—F 1-009-13, ABN SI LWET FZ—F 1—009—54, ABN SI LWET FZ—2222 and the like. Among them, from the viewpoint of flexibility, smoothness, drapability, mildness, and quick drying, SH3775M, BY Preferred are silicones such as 22-008, KF 6017, SI LWET FZ-2171 ABN SIL WET FZ-F 1-009-54, ABN SI LWET FZ-2222. These can be used alone or as a mixture of two or more.

 The amount of the silicone compound (A) used in the present invention is not particularly limited, but may be selected from the viewpoints of flexibility, smoothness, drapability, mildness, quick drying, water absorption and viscosity of the composition. The amount is 3 to 70% by weight, preferably 5 to 50% by weight, more preferably 6 to 40% by weight in the composition. If the amount is less than 3% by mass, effects such as flexibility, smoothness, drapability, mildness, quick drying, and water absorption may be insufficient. If the amount exceeds 70% by mass, the viscosity of the composition becomes high. And the usability may decrease.

 The component (B) of the present invention has an effect of adsorbing the silicone compound (A) to the fiber. As the water-soluble polymer compound having a cationic property, a compound having a cationic property when dissolved in water can be used. As the cationic water-soluble polymer compound, a water-soluble polymer compound having at least one kind of cationic group selected from an amino group, an amine group, and a quaternary ammonium group is preferable. In the present invention, the term "water-soluble polymer compound" refers to a compound that is not turbid and is transparent when 1 g of a water-soluble polymer compound is added to 100 g of water at 25 ° C. .

 The cationic water-soluble polymer compound (B) preferably has a degree of cationization of 0.1% or more, particularly preferably 2.5% or more. If the degree of cationization is less than 0.1%, the effect of adsorbing the coexisting silicone compound on the fiber is reduced, and a large amount of the compound is required, which may not be economical. In addition, when the polymer compound itself has a property of imparting rigidity to a fiber product, a large amount of the compound may decrease the softening effect.

Here, the degree of cationization means that the polymer compound is a polymer of a cationic monomer, a copolymer of a cationic monomer and a nonionic monomer, and a part of a nonionic polymer modified or modified with a cationic group. In the case of a substituted one (cationized cellulose or the like), the following formula (1) is used, and the polymer compound is a copolymer of a cationic monomer and an anionic monomer; and a cationic monomer, an anionic monomer and a nonionic monomer. In the case of a copolymer of a reactive monomer, it is defined as a value calculated by the following formula (2). Degree of cationization (%) = XXYX 100… formula (1)

(X: Atomic weight of cationized atoms (such as nitrogen) in the cationic group of the polymer compound

 Υ: Number of moles of cationic group contained in 1 g of polymer compound)

 Degree of cationization () = XX (Y-Z) X 100… Equation (2)

 [X: atom of cationized atom (nitrogen, etc.) in cationic group of polymer compound Y: number of moles of cationic group contained in 1 g of polymer compound

Z: number of moles of anionic group contained in 1 g of polymer compound

 (The anionic group of Z includes, for example, a carboxyl group, a sulfonic acid group, and the like contained in one monomer unit in the polymer compound chain. Specifically, a carboxylic acid in acrylic acid, etc. Does not include the counter ion of the cationic group.

 As a calculation example of the degree of cationization, the case of MERQUAT280 (manufactured by ca1gon) represented by the following formula is shown.

 X: 14 (atomic weight of nitrogen atom)

 Y: 4.95 X 10-3 (weight based on cationic group: 0.8 g and calculated from molecular weight of cationic group)

Z: 2. 78 X 10- ³ (weight in 1 g of Anion groups: calculated from the molecular weight of 0. 2 g and Anion group)

 From equation (2),

 Degree of cationization (%) =

^{14 X (4. 95 X 10- 3} - 2. 78 X 10 one ³⁾ X 100 = 3. 0.

 (MERQUAT 280)

 The mass ratio of dimethyldiarylammonium chloride to acrylic acid = 80: 20 Therefore, according to the above-mentioned method of calculating the degree of cationization, the cationization of the polymer of the nonionic monomer and the polymer of the anionic monomer was carried out. The degree is 0.

If it is less than 1,000, it may not be preferable in terms of odor. If it is more than 5,000,000, the viscosity of the composition may increase, and the usability may decrease.

 Further, from the viewpoint of mildness, it is preferable that the weight average molecular weight is large within the above range, and it is preferable that the number of low molecular weight compounds such as unreacted substances which are unavoidably mixed during the production is as small as possible.

Examples of the (B) component include MERQUAT100 (manufactured by Calgon), Adeshi Kachi Ace PD-50 (manufactured by Asahi Denka Kogyo Co., Ltd.), Daidol EC-004, Daidol HEC, and Daidol EC (Daido Kasei Kogyo ( Co., Ltd.), dimethyldiarylammonium polymer such as MERQUAT 550 JL5 (manufactured by Calgon), ME RQUAT280 Dimethyldiarylammonium / acrylic acid copolymers such as Calgon, cationized cellulose such as Leogard KGP (Lion), LUV I QUAT—FC 905 (BASF) Imidazolium chloride 'vinylpyrrolidone copolymer, polyethyleneimine such as LUGALVAN-G15000 (manufactured by BAS F), Poval CM318 (manufactured by Kuraray Co., Ltd.), etc. Examples include natural polymer derivatives having an amino group such as cationized polyvinyl alcohol and chitosan, and copolymers with a vinyl monomer having a lyophilic group to which ethylamino methacrylate and ethylene oxide are added.

If the proportion of the component (B) is larger than this range, the softness and smoothness of the silicone compound imparted to the skin are impaired, which is not preferable. In particular, in the case of a polymer compound that imparts stiffness to the fiber by the component (B) alone, since the flexibility and smoothness imparted by the silicone compound are not impaired, the proportion of the component (B) is within this range. It is preferable that the number is as small as possible. On the other hand, when the proportion of the component (B) is less than this range, the adsorptivity of the silicone to the fiber is reduced, which is not preferable.

Water absorption evaluation method

 (Preparation of test cloth)

Commercial cotton towel (100% cotton) and polyester satin (100% polyester) ) Is washed with a household two-tub washing machine for 15 minutes using a commercially available laundry detergent “Top” (detergent used in a standard amount, bath ratio of 30 times, 45 ° C tap water). The treatment was repeated for two cycles. Then, the process of rinsing with running water for 15 minutes and dewatering for 5 minutes was repeated 5 times, and the sample was air-dried to obtain a test cloth.

 (Treatment with softener)

 80 g of cotton wool or 20 g of polyester satin obtained from the preparation of the test cloth described above was added to a softener composition of 1 g per 3 liters of water (however, 2 g in Example 36 and 0 in Example 37). 7 g, 0.5 g for Example 38, and 2 g for Examples 39 to 42), the test cloth was softened (bath ratio 30 times, using tap water at 25 ° C, 3 minutes). Then, it was air-dried under the conditions of 20 ° C. and 45% RH and evaluated as follows.

 (Water absorption evaluation method)

 The water absorption of the cotton towel and the polyester satin was measured by the following method, respectively, and evaluated according to the following evaluation criteria.

 (1) Water absorption of cotton towel

 A piece of cloth cut out to a size of 2.5 cm x 20 cm from the cotton towel treated as described above is suspended vertically at 20 ° (: 45% RH), and tap water is used from the lower end using capillary action. The water absorption height was measured 10 minutes after the moment when the lower end was brought into contact with tap water.The higher the water absorption height, the better the water absorption. (Equivalent to JIS, Villeda method) ).

 (2) Water absorption of polyester satin (synthetic fiber)

 One drop of ion-exchanged water was dropped on the polyester satin cloth treated as described above, and the time required for complete permeation was measured visually.

 X: Water absorption length of cotton is less than 50 mm

Quick drying evaluation method

(Preparation of test cloth) There are two ways to improve quick drying: increasing the evaporation rate of water and decreasing the water content after dehydration. In order to increase the evaporation rate of water, it is conceivable to azeotropically evaporate with an organic solvent such as ethanol which easily azeotropes with water. It is impractical to perform at home because organic solvents must be used in large quantities. Therefore, we focused on reducing the moisture content after dewatering and decided to evaluate quick drying. Wash a commercially available cotton towel (100% cotton) with a two-tub washing machine for household use using a commercial laundry detergent “Top” 15 minutes (standard amount of detergent, bath ratio 30 times, 45 ° C tap water ) → Dehydration The treatment was performed by repeating the 5-minute process for 2 cycles. Thereafter, the process of rinsing with running water for 15 minutes → dehydration for 5 minutes was repeated five times, and the test cloth was sufficiently dried at 20 ° C and 60% RH. The mass (Wd) of the dried olive after drying was measured and used for the following moisture content calculation.

 (Treatment with softener composition)

 Two pieces of cotton wool ore obtained in the preparation of the test cloth were used, and the softener composition was applied to 4.8 liters of water at 2.4 g (however, Example 36 was 4.8 g, and Example 37 was 4.8 g). 1.6 g, 1.2 g for Example 38, and 4.8 g for Examples 39 to 42) With the added liquid, soft treatment of the test cloth (bath ratio 30 times, using tap water at 25 ° C, 3 Minute) Thereafter, dehydration was performed for 1 minute using a washing machine (CW-C30A1-H) manufactured by Mitsubishi Electric Corporation.

 (Quick drying evaluation method)

 The mass (Ww) of the cotton wool immediately after dehydration in the softener treatment was measured, and from this value and the mass (Wd) of the dried towel before the softener treatment, the moisture content was calculated by the following formula (3). . In addition, the moisture content (B1) of the Watayu Oru that had been subjected to the above treatment without using a softener was also calculated by the following equation (3), and the relative moisture rate was calculated by the following equation (4). The quick drying property was evaluated by

Ww (g) -Wd (g)

 Moisture percentage (% by mass) = X I 00 Equation (3)

 Wd (g) Moisture percentage of treated cloth (% by mass)

Relative moisture content (%) = XI 00 formula ( ₄₎

BI <Quick drying evaluation criteria>

 ：: Relative moisture content is less than 88%

〇: Relative moisture content is 88% or more and less than 94% △: Relative moisture content is 94% or more and less than 100% X: Relative moisture rate is 100% or more
