Description

  The present invention relates to a finishing composition for clothing and a method for treating clothing using the same.

  In recent years, knitwear with excellent fashion has been increasing. The knit clothing is required to have a supple texture as compared with a cloth such as a sheet or a Y-shirt which is a target clothing of the paste composition. Knitwear is made up of a knit knitting method using a yarn in which single fibers are sweetly twisted compared to a fabric. In knit knitting, twisted yarns and single fibers constituting the yarn are easy to move, giving the clothing a supple texture.

  The clothing is composed of yarn, and the yarn is composed of monofilament. The clothing rubs against each other due to use or wear, and the clothing rubs against an object other than clothing such as a chair, thereby causing fuzz and fluff. Further, when the fluff and fluff are generated, irregularities are generated on the surface, and when the irregularities are exposed to light, shadows are generated, so that the color of the clothing looks dull, which is not aesthetically pleasing. In particular, when pills are generated, shadows are prominently generated, which increases aesthetic issues.

  Since knit clothing uses a yarn in which single fibers are sweetly twisted, the single fibers are easily removed from the yarn, and fluff and fluff are likely to occur. Therefore, when washing knitted clothing, it has been practiced to immerse and process the knitted clothing in a container such as a wash basin. A cleaning agent has been proposed that can be treated and can suppress the generation of fluff and fluff.

For example, Patent Document 1 discloses a fiber mainly composed of an aqueous dispersion such as a (meth) acrylic acid ester-based copolymer whose glass transition temperature is −45 ° C. to 20 ° C. and further containing a wetting agent. A processing resin composition is disclosed. Furthermore, this patent document 1 describes nonionic surfactants such as polyoxyethylene alkyl ethers as wetting agents.
Patent Document 2 discloses a paste composition containing an emulsion obtained by emulsion polymerization using monomers such as alkyl methacrylate and the like during emulsion polymerization of a lower fatty acid vinyl ester and an unsaturated carboxylic acid. Has been. Further, Patent Document 2 describes that a nonionic emulsifier is used at the time of polymerization, and that a cationic polymer such as cationized starch may coexist at the time of polymerization, or may be added after the completion of polymerization.
Patent Documents 3 to 5 contain a (meth) acrylic acid ester having a C 1-16 alkyl group as a constituent unit, a polymer having a glass transition temperature of −40 ° C. or more and less than 0 and a cationized starch. A finishing composition is disclosed.
Patent Documents 6 to 7 disclose aqueous pigment compositions containing a pigment, an acrylate emulsion, a high-boiling water-soluble organic solvent, and the like. Furthermore, Patent Document 8 discloses an emulsified composition containing a softener and a water-soluble mono- or polyhydric alcohol.
In addition, in patent documents 1-5, when a finish composition is used using the finish holding part of a fully automatic washing machine, the aggregate of a finish composition adheres to a textile product, and an external appearance deteriorates. There is no description about this.
Moreover, the techniques described in Patent Documents 6 to 8 do not assume processing in a fully automatic washing machine.

The present inventors have found that there is a new problem when processed with a specific fully automatic washing machine in a garment finishing composition capable of suppressing the occurrence of fluffing and fluffing of clothing. Specifically, it is as follows.
In a fully automatic washing machine, when the finishing agent is put in the finishing agent holding part (case) of the fully automatic washing machine at the start of washing, the finishing agent is automatically put into the washing tub at the final rinse. However, there are the following two methods as the input method. In the first method, the finishing agent put into the finishing agent holding part (case) provided in the washing tub moves inside the finishing agent holding part by the centrifugal force at the time of dehydration, and moves to the washing tub at the final rinse. The “injection case method” is used. The second method is an “injection method” in which water is injected while dissolving the finishing agent with tap water supplied from the dedicated water supply valve for supplying the finishing agent during the final rinsing. Is. The present inventors have noticed that a unique problem occurs when the first type automatic washing machine is used. That is, when the finishing process is performed using the first type “input case type” fully automatic washing machine, agglomerates of the finish composition tend to occur, and sometimes a string-like or film-like agglomerate. Noticed the problem of sticking to textiles.

[Clothing finishing composition]
The finishing composition for clothing of the present invention contains 70% by mass or more and 100% by mass or less of a structural unit derived from a (meth) acrylic acid ester (a1) having an alkyl group having 1 to 16 carbon atoms, and Polymer (A) having a glass transition temperature of −40 ° C. or higher and lower than 0 ° C., cationized starch (B), cationic compound (C) represented by the following general formula (1), having 2 to 4 carbon atoms It contains a divalent or trivalent water-soluble polyhydric alcohol (D) and water, and the amount of the component (D) relative to 100 parts by mass of the component (A) is 100 parts by mass or more and 300 parts by mass or less (D ) A finishing composition for clothing in which the amount of component (C) is from 0.5 parts by weight to 10 parts by weight with respect to 100 parts by weight of component.

(In the formula, R ¹ represents a hydrocarbon group having 12 to 18 carbon atoms, R ³ represents an alkyl group having 1 to 4 carbon atoms, a benzyl group, and a hydroxyalkyl group having 2 to 4 carbon atoms. R ² represents a group defined by R ¹ or R ³ , and X ⁻ represents an anion.)

In solving the above problems, the present inventors have found that the composition remains in the finishing agent holding part of the fully automatic washing machine of the “input case method” and the polymer particles are likely to aggregate due to the volatilization of water. As a result, it was thought that the aggregate of the finishing composition for clothing easily adheres to the fiber product. Furthermore, the present inventors have found that another cause is the physical properties of the polymer. Specifically, at a tap water temperature of about 5 to 40 ° C. usually used for washing, a polymer having a glass transition temperature of less than 0 ° C. exhibits soft physical properties, and the polymer exhibiting the soft physical properties aggregates with cationized starch. Therefore, it was considered that the aggregates easily adhere to the fiber product.
Therefore, the present inventors have made various studies, and contain a specific unit, a polymer exhibiting a specific glass transition temperature, a cationized starch, a cationic compound, a water-soluble polyhydric alcohol, and water in a specific ratio. This can suppress the occurrence of fluff and fluff on textile products such as clothing, and when using the finishing agent holder (case) of a fully automatic washing machine of the input case method, It has been found that adhesion of the composition aggregates can be suppressed.

In the present specification, “(meth) acrylic acid ester” means “acrylic acid ester, methacrylic acid ester, or a mixture thereof”.

That is, the log P value is an index of lipophilicity (hydrophobicity). The larger the value, the more hydrophobic, and the smaller the value, the more hydrophilic.
For the log P value, see, for example, Daylight Chemical Information Systems, Inc. The logP values of many compounds are listed in databases available from (Daylight CIS) and can be referred to. Further, when there is no actually measured logP value, it can be calculated by a program “CLOGP” (Daylight CIS) or the like, and among them, calculation by the program “CLOGP” is preferable because of high reliability.
In the program “CLOGP”, the value of “calculated logP (ClogP)” calculated by the Hansch, Leo fragment approach is output together with the measured value of logP, if any. The fragment approach is based on the chemical structure of the compound and takes into account the number of atoms and the type of chemical bond (A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. et al. B. Taylor and CA A. Ramsden, Eds., P. 295, Pergamon Press, 1990). Since this ClogP value is currently the most common and reliable estimate, it is preferable to use the ClogP value instead when there is no measured value of logP when selecting a compound. In the present invention, either the measured value of logP or the ClogP value calculated by the program “CLOGP” may be used.
