Description

  The present invention relates to a method for treating textile products.

In recent years, the amount of water used for washing has been decreasing due to increasing environmental awareness. On the other hand, the amount of items to be washed per wash is increasing due to the increase in size of washing machines. As a result, the bath ratio during washing (mass of washing water / mass of the object to be washed) is decreasing. Under such washing conditions in which the amount of water used is small, dirt such as sebum tends to remain on the textile product being washed, and odors (such as sebum odor) may be felt from the textile product after washing.
In addition, consumers are becoming more aware of savings, and when washing with a washing machine, the rate of selecting a speed course that completes processing in a shorter time than a normal washing course is increasing. In the speed course, the cleaning time is shortened, so that it may be difficult to remove dirt compared to the normal course.
Recently, in order to impart a fragrance to textile products, softeners are often used at the time of rinsing after washing. However, if sebum odor remains in the textile products after washing, May not feel enough.
The technique of patent documents 1-3 exists regarding the washing | cleaning agent which suppresses the smell or stain | pollution | contamination of textiles.
The technique of patent documents 4-5 exists regarding the softening agent which suppresses the odor of a textile product.

Step 2: a step of dehydrating the fiber product washed in Step 1, and a step 3: a step of treating the fiber product dehydrated in Step 2 with a liquid softener composition. Hereinafter, each process is explained in full detail.

Process 1
Step 1 is a step of washing a textile product using a liquid detergent composition containing the component (A).

(A) component (A) component is mix | blended as a washing | cleaning component of a textile product.
The component (A) is one or more nonionic surfactants represented by any of the following general formulas (1-1) to (1-3).

Nonionic surfactant R ¹ —CO— (EO) _n —OR ² (1-1) represented by the general formula ( 1-1)
(Where
R ¹ is a hydrocarbon group having 9 to 13 carbon atoms,
R ² is an alkyl group having 1 to 4 carbon atoms,
EO is an oxyethylene group,
n shows the average repetition number of EO, and is a number of 5-25. )

In general formula (1-1), the hydrocarbon group represented by R ¹ may be linear or branched, or may contain a cyclic structure. The hydrocarbon group for R ¹ is preferably an aliphatic hydrocarbon group, and a linear or branched alkyl group or a linear or branched alkenyl group is more preferable. .
R ¹ has 9 to 13 carbon atoms, preferably 10 to 13 carbon atoms, and more preferably 11 to 13 carbon atoms. When the carbon number of R ¹ is 9 or more, the detergency increases. On the other hand, when the carbon number of R ¹ is 13 or less, the liquid stability is improved, and particularly gelation is suppressed.
In the general formula (1-1), R ² is an alkyl group having 1 to 4 carbon atoms, preferably an alkyl group having 1 to 3 carbon atoms. Specific examples of R ² include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, and an n-butyl group. A methyl group and an ethyl group are preferable, and a methyl group is more preferable. When the carbon number of R ² is 1 or more, precipitation during low-temperature storage is easily suppressed. On the other hand, when the carbon number of R ² is 4 or less, the solubility of the liquid detergent in water under low temperature conditions is increased.
In said Formula (1-1), n shows the average repeating number of an oxyethylene group (EO), and is a number of 5-25. When n is at least the lower limit value, the cleaning power, particularly the cleaning power against sebum stains is improved. On the other hand, the solubility with respect to the water of a liquid detergent improves that n is below an upper limit.
n is preferably from 5 to 20, and more preferably from 12 to 18.

  It is preferable that the narrow rate which shows the ratio of the distribution of the compound from which the repeating number of EO in General formula (1-1) differs is 20 mass% or more. It is preferable that the upper limit of the narrow ratio is substantially 80% by mass or less. The narrow ratio is more preferably 20 to 50% by mass, and more preferably 30 to 45% by mass because the liquid stability and the solubility in water are further improved. The higher the narrow rate, the easier it is to obtain good detergency. Further, when the narrow ratio is preferably 20% by mass or more, and particularly preferably 30% by mass or more, a liquid detergent composition with less raw material odor can be easily obtained. This is because, after the production of the component (A) represented by the general formula (1-1), the fatty acid ester which is a raw material of the component (A) coexists with the component (A) and the general formula (1-1). This is because the number of ethylene oxide adducts in which n is 1 or 2 decreases.

When the carbon number of R ³ is within the above range, the detergency and gelation resistance are excellent. The alkyl group or alkenyl group for R ³ may be linear or branched. R ³ may be derived from a raw material alcohol (R ³ —OH). Examples of the alcohol include alcohols derived from natural fats and oils such as coconut oil, palm oil, and beef tallow, and synthetic alcohols derived from petroleum.

In general formula (1-2), q shows the average repeating number of an oxypropylene group (PO), is the number of 1-4, and 1-3 are preferable. When q is within the above range, good foaming properties during rinsing and prevention of gelation of the liquid detergent composition can be obtained.
The addition form of EO and PO in the general formula (1-2) may be random addition or block addition. Block addition can be performed by a method of adding PO after adding EO or a method of adding EO after adding PO. In particular, from the viewpoint of good rinsability in washing with a fully automatic washing machine, it is preferable to add EO and PO, then add EO, and have an EO chain at the end.
In addition, the addition mole number distribution of PO and EO in the compound represented by the general formula (1-2), that is, the distribution of p, q, and r is not particularly limited. These distributions vary depending on the reaction method during production of the compound. For example, when a general alkali catalyst such as sodium hydroxide or potassium hydroxide is used and ethylene oxide is added to the hydrophobic raw material, the distribution tends to be relatively wide. Further, for example, metal ions such as Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ and Mn ²⁺ described in Japanese Patent Publication No. 6-15038 are added.
