Description

  The present invention relates to a garment finishing composition and a garment processing method 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 to the cloths such as sheets and Y-shirts that are the target clothing of the paste composition. The knit clothing is configured by a knitting method called knit knitting using a yarn obtained by twisting a single fiber sweetly compared to a fabric. Knit knitting gives a flexible texture to the entire garment because the yarns and the single fibers constituting the yarn are easy to move.
The apparel is made of yarn, and the yarn is made of monofilament. It is known that clothing is fuzzed or fuzzed by friction when the clothing is rubbed by use or when the clothing rubs against an object other than clothing such as a chair. 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 the knit clothing uses a yarn in which single fibers are twisted sweetly, 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 treat the knitted clothing in a container such as a wash basin. There has been proposed a cleaning agent capable of suppressing the generation of fluff and fluff while being able to do so.
For example, Patent Document 1 includes an aqueous dispersion such as a (meth) acrylic acid ester-based copolymer whose glass transition temperature is −45 ° C. to 20 ° C. as a main component, and further contains a wetting agent. A resin composition for fiber processing is disclosed. Furthermore, this patent document 1 describes cationic surfactants such as quaternary ammonium salts as wetting agents.
Patent Document 2 discloses that a glass transition temperature obtained by emulsion polymerization of a mixture of monomers and the like selected from the group consisting of acrylic acid esters and methacrylic acid alkyl esters using a cationic emulsifier is 0 to 30 ° C. An antibacterial resin composition for laundry glue containing a cationic acrylic emulsion of a copolymer and a cationic antibacterial agent is disclosed. In Patent Document 2, compounds such as lauryltrimethylammonium chloride are described as cationic emulsifiers, and cationic antibacterial agents such as didecyldimethylammonium chloride are also described.

  Patent Document 3 describes a paste composition containing an emulsion obtained by emulsion polymerization using a monomer such as an alkyl methacrylate ester during emulsion polymerization of a lower fatty acid vinyl ester or the like and an unsaturated carboxylic acid. Yes. Further, Patent Document 3 describes that a cationic polymer such as cationic starch can coexist at the time of polymerization or can be added after the completion of polymerization.

JP 2008-248432 A JP 2001-226204 A JP-A-3-260174

The present inventors include a finishing composition for clothing as described in Patent Documents 1 to 3, that is, contains a specific polymer, a cationic component, and water, and suppresses the occurrence of fluffing and fluffing of clothing. It was found that there is a new problem in the finish composition for clothing that can be made.
That is, in a garment finish composition capable of suppressing the occurrence of fluffing and fluffing of clothing, the garment is brought into contact with water having a specific alkalinity in a finishing agent inlet of a washing machine. It has been found that there is a problem that a part of the finishing agent composition adheres to the finishing agent inlet (liquid residue) and the finishing agent inlet has an aesthetically unfavorable appearance.

When the present inventors diligently investigated this problem, the above problem was caused by the effects of carbonate ions (CO ₃ ²⁻ ), hydrogen carbonate ions (HCO ₃ ⁻ ) and the like in water, which are factors of carbonate alkalinity. I found out that it was caused by ions. Specifically, the anion exchanges with a counter ion (generally a chlorine ion) of the cationized starch of the cationized starch in the garment finish composition, thereby reducing the surface potential of the cationized starch. It is considered that the charge repelling force is weakened and the polymer particles are easily agglomerated, so that the finish composition for clothing is likely to adhere (liquid residue) to the charging port.

  Furthermore, it has been found that another cause is the physical properties of the polymer. That is, at a temperature of tap water 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 together with cationized starch and is charged. It is thought that it becomes easy to adhere to the mouth.

In Patent Documents 1 to 3, in the case where a polymer having a glass transition temperature of −45 ° C. to 20 ° C. and a quaternary ammonium compound as a wetting agent are used, CO in tap water is added to the inlet of the washing machine. ₃ ^2- and HCO ₃ ^- is contamination due to anions such no description relates to occur. However, it does not describe preventing contamination of the inlet by scavenging (capturing) anions such as CO ₃ ⁻ and HCO ₃ ⁻ in tap water.
[0017] of Patent Document 2 describes that the glass transition temperature of the emulsion polymerization latex is in the range of 0 to 30 ° C. Further, it is described that when the glass transition temperature is less than 0 ° C., fluffing may occur. This document does not describe a technical idea that suppresses the removal of the single fiber from the yarn by setting the glass transition temperature to less than 0 ° C. [0023] describes that it can be used as it is as a laundry paste or diluted in “water”. The subject at the time of using it in the presence of a specific anion which is a technical subject of this application is not described.
In patent document 3, the adsorptivity of a polymer is improved using cationized cellulose or cationized starch. However, the upper right column on page 4 of Patent Document 3 describes that the alkyl acrylate ester contains at most 30 parts by weight with respect to 100 parts by weight of the vinyl acetate monomer. When the content of vinyl acetate in the polymer is large, there is a problem that the effect of suppressing fluffing and generation of fuzz is reduced.
The present invention has been made in view of the above-described conventional problems, and in a garment finish composition capable of suppressing the generation of fuzz and fluff of textile products such as garments, a liquid is added to the inlet of a washing machine. Provided is a garment finish composition that does not cause a residue, and a method for treating garments using the garment finish composition.

The present inventors have revealed that performing studies to solve the above problems, CO ₃ ^2-and HCO ₃ in tap water ^- and the like of the anion, by trapping with a compound having a quaternary ammonium group in the molecule, It has been found that aggregation of components in the finishing composition for clothing can be suppressed, and liquid remaining at the finishing agent inlet of the washing machine can be suppressed.
The present invention provides the following [1] and [2].
