Description

  The present invention relates to a cleaning agent for textile products, and more particularly to a cleaning agent suitable for cleaning clothing and dust control products.

  Conventionally, polyoxyethylene alkyl ether nonionic surfactants are sometimes used in detergents for textile products such as clothing and dust control products. Here, the dust control product is generally a product such as a mop or mat that is lent to a customer from a dust control company, collected from the customer after use, rented again as a new product after cleaning. Such a dust control product is a pile on the surface of a product to which oil as an adsorbent is applied, and traps dust and dirt. After the washing, the product is made into a product by attaching oil. Therefore, it is required to remove both dirt and oil during cleaning after collection.

  For example, Patent Document 1 listed below contains an inorganic alkaline agent, a nonionic surfactant containing an oxyethylene group and an oxypropylene group, a specific ether compound, and water as a cleaning agent used in the linen industry and dust control industry. What to do is disclosed. However, the nonionic surfactant is obtained by adding ethylene oxide or propylene oxide to an alcohol having an alkyl group or alkenyl group, and a nonionic surfactant comprising an ethylene oxide adduct of styrenated phenol is disclosed. Not. Further, as the above-mentioned specific ether compound, those containing a phenyl group such as triethylene glycol monophenyl ether are disclosed, but the number of added moles of ethylene oxide is 1 to 3, and nonionic surface activity It does not act as an agent.

Thus, conventionally, as an ethylene oxide addition type nonionic surfactant for use in a textile cleaning product for clothing or the like, those based on alcohols having an alkyl group or an alkenyl group are mainly used. In addition, those based on those having an aromatic ring such as styrenated phenol have not been used for washing textile products. In addition, although the nonionic surfactant which consists of an ethylene oxide adduct of styrenated phenol was conventionally known as a washing | cleaning use of hard surfaces like a metal (refer the following patent documents 2 and 3), it is the object of washing | cleaning. Because of the difference, it has not been considered to use it for washing textiles such as clothing.
Japanese Patent Laid-Open No. 2004-244591 JP-A-08-108153 JP-A-10-130691

  In recent years, fiber products using recycled resin such as polyethylene terephthalate are increasing, but there is no suitable cleaning agent, and existing cleaning agents are used in combination. However, due to the difference in materials, the ability of conventional cleaning agents is not sufficient, and there are problems with cleaning properties and recontamination properties.

  The present invention has been made in view of the above points, and it is intended to provide a fiber product cleaning agent that exhibits excellent detergency and anti-recontamination property even for fiber products using recycled resin. Objective.

  The detergent for textiles which concerns on this invention contains the nonionic surfactant represented by following General formula (1).

R ¹ O (A ¹ O) _m H (1)
In the formula, R ¹ represents a hydrocarbon group having 6 to 18 carbon atoms and containing at least one aromatic ring. A ¹ O represents an oxyethylene group or an oxypropylene group, and these may be used alone or in combination of two. m represents an average added mole number, and is 5-20.

  In the detergent for textiles according to the present invention, the first nonionic surfactant represented by the general formula (1) and the second nonionic surfactant represented by the following general formula (2) It is preferable that 1-99 weight part of said 1st nonionic surfactant is contained with respect to 100 weight part of the total amount of both.

R ² O (A ² O) _n H (2)
In the formula, R ² represents an alkyl group or alkenyl group having 6 to 14 carbon atoms. A ² O represents an oxyethylene group or an oxypropylene group, and these may be used alone or in combination of two. n represents the average added mole number and is 1-20.

  About each obtained cleaning agent, the washing | cleaning rate (cleaning property) and the recontamination rate (recontamination prevention property) were measured and evaluated by the following method. The results are shown in Tables 1 and 2.

(Washing rate)
8cm x 8cm polyester fabric (woven fabric using polyester fiber regenerated from PET bolts (Ecopet, manufactured by Teijin Ltd.)) and nylon fabric (made by DuPont) using a fabric contamination machine, What adhered 3g and mineral oil 3g was used as a contaminated cloth. The contaminated cloth was subjected to a washing test under a washing condition of 100 rpm, 50 ° C., 10 minutes, bath ratio (contaminated cloth / water) = 1/33, using a targotometer as a washing tester. The cleaning agent concentration was 0.1% by weight.

The washing rate was calculated using the following equation after measuring the uncontaminated cloth and the reflectance before and after washing using a color difference meter “TC-1500SX” manufactured by Tokyo Denshoku Co., Ltd.
Washing rate (%) = {(reflectance after washing−reflectance before washing) / (reflectance of uncontaminated cloth−reflectivity before washing)} × 100
The evaluation is to obtain an average value of the cleaning rate of the three contaminated cloths, “◎” when the cleaning rate is 50% or more, “◯” when 20% or more and less than 50%, and 10% or more and less than 20%. Is “△”, and less than 10% is “×”.

(Recontamination rate)
The re-contamination rate is the same as that of the above-mentioned cleaning rate. A white cloth (non-contaminated cloth) is added at the same time. And measured by the following formula.
Recontamination rate (%) = {(reflectance of white cloth before washing−reflectance of white cloth after washing) / (reflectance of white cloth before washing)} × 100
For the evaluation, the average value of the re-contamination rate of three white cloths is obtained, “◎” when the re-contamination rate is less than 10%, “○” when the re-contamination rate is less than 10%, and less than 20% and less than 30%. “△” was given for the product, and “x” for 30% or more.

  As shown in the above table, the cleaning agents of the examples were excellent in cleaning properties and anti-recontamination properties for both polyester fabrics using recycled resins and nylon fabrics that are conventional textile products. . In particular, in Examples 3 to 6, a more excellent effect was achieved by using the second nonionic surfactant together and further using the inorganic alkaline agent.

On the other hand, in Comparative Examples 1 to 3, the nonionic surfactant used in the above general formula (1) had an added mole number m of EO smaller than the specified range, and therefore was poor in detergency. In Comparative Examples 4 and 5, the second nonionic surfactant represented by the general formula (2) is blended, but the first nonionic surfactant is not blended. It was inferior to. In Comparative Examples 6 and 7, as the nonionic surfactant, a compound having an added mole number m of EO in the general formula (1) larger than the specified range was used, so that both the cleaning property and the recontamination preventing property were inferior. It was. In Comparative Examples 8 and 9, since the nonionic surfactant having a carbon number of R ¹ larger than the specified range in the general formula (1) is used, both the cleaning property and the recontamination preventing property are inferior. It was.

  The detergent for textiles of the present invention can be used for washing various textile products including textiles using recycled resin, and can be suitably used as a detergent for clothing and a detergent for dust control.
