Description

  The present invention relates to an article for treating textile products.

  When a textile product such as washed clothes is dried with a dryer, a textile product processing article in which a textile product treating agent is supported on a substrate such as a nonwoven fabric is brought into contact with the textile product. When such a treatment is performed, the component carried on the textile product processing article adheres to the textile product and is expected to have a desired effect. In such applications, as a textile treatment agent, conventionally, for the purpose of imparting flexibility and antistatic properties, those having a cationic surfactant as a main base have been used (for example, Patent Document 1). Recently, a combination of a specific silicone compound and a compound having a high melting point has been proposed for the purpose of removing wrinkles formed by washing (Patent Document 2).

In the combination, any fiber may be selected as the core material or the sheath material.

There is no restriction | limiting in particular as a manufacturing method of the said nonwoven fabric, According to the objective, it can select suitably from well-known manufacturing methods, such as a dry method and a wet method. Specific examples of the method for producing the nonwoven fabric include a spunbond method, a chemical bond method, a thermal bond method, and a spunlace method.
In the spunbond method, a resin chip having a low melting temperature such as polypropylene is usually heated and melted, long fibers are extruded from a nozzle, and a plurality of the long fibers are stacked on a belt conveyor to form a web. In this method, the web is thermally welded with a hot roll.
In the chemical bond method, a relatively long short fiber is usually opened and stirred by an air flow, and a web is formed by feeding the fiber in a certain amount and in a certain direction with a needle provided on a belt conveyor. In this method, a binder (adhesive resin) is applied to the web by spraying, and heated and dried to adhesively bond the fiber intersections.
In the thermal bond method, normally, relatively long short fibers are opened and agitated by an air flow, and a web is formed by feeding fibers in a certain amount and in a certain direction with a needle provided on a belt conveyor. In this method, the low melting point fibers in the web are welded with a roll or hot air to bond the fibers together.
In the spunlace method, a relatively long short fiber is usually opened and agitated by an air flow, and a web is formed by feeding the fiber in a certain amount and in a certain direction with a needle provided on a belt conveyor. This is a method in which webs are laminated, and a special needle having a minute projection called barb is reciprocated at high speed with respect to the laminated webs so that fibers are entangled.

[1. Clothing pretreatment]
One piece of polo shirt (100% cotton, made by Uniqlo) and one long sleeve Y-shirt (100% cotton, made by Uniqlo) were prepared as clothing.
These clothes are washed in a fully automatic washing machine ("AW-F80HVP" manufactured by Toshiba Corporation) in hot water of 50 ° C for 10 minutes, rinsed twice, dehydrated 4 minutes 3 times, and hung on a hanger. Dried and dried naturally.

[2. Cleaning process]

Immediately after the completion of dehydration, three textile processed articles were placed in the drum-type washing and drying machine and dried together with clothing for 3 hours.
As a blank, a drying treatment was performed in the same manner as described above without adding a textile processed article.

[4. Evaluation]
(4-1. Wrinkle suppression)
Visual judgment was made about the state of wrinkles on the back part of the polo shirt after the drying treatment. The evaluation was performed according to the following criteria, and an average of 10 evaluators was calculated to give a score of 3.5 or higher.
5 points: no wrinkles, 4 points: almost no wrinkles, 3 points: some wrinkles, 2 points: quite wrinkles, 1 point: very wrinkles
(4-2. Iron slipperiness)
Evaluation was performed by applying an iron (Panasonic Electric Works Co., Ltd. (former Matsushita Electric Industrial Co., Ltd., “Steam Iron NI-SF31”, temperature: high (cotton)) to the back of the long-sleeved Y-shirt after the drying treatment.
The evaluation was made according to the following criteria compared with the blank, the average of 10 evaluators was calculated, and 3 or more points were evaluated as good.
5 points: much easier to slide than blanks 4 points: much easier to slide than blanks 3 points: easier to slip than blanks 2 points: equivalent to blanks 1 point: less slippery than blanks
(4-3. Offensive odor prevention)
The odor immediately after opening the drum type laundry dryer after the drying treatment was evaluated according to the following criteria. The average score of 10 evaluators was calculated, and a score of 3.5 or higher was considered good.
5 points: no off-flavor at all, 4 points: almost no off-flavor, 3 points: a little off-flavor, 2 points: a very off-flavor, 1 point: a very off-flavor.
(4-4. Water absorption)
One drop of ion-exchanged water and a tip of the dropper were brought close to the clothing surface with 2 mL polydropper on the back surface of the polo shirt after the drying treatment, and scored according to the following criteria. Ten average points were calculated, and 3 or more points were evaluated as good. The blank was 3 points.
5 points: soaks within 1 second, 4 points: soaks within 1 to 2 seconds, 3 points: soaks within 2 to 3 seconds, 2 points: soaks within 3 to 4 seconds, 1 point: 4 seconds I don't soak.

As shown to the said result, generation | occurrence | production of the strange odor and wrinkles were suppressed and the iron slidability was also favorable for the clothing which performed the drying process using the textiles processing goods of Examples 1-29. Also, the water absorption was good.
On the other hand, when the textile product processing article of Comparative Example 1 in which lauric acid was blended instead of the component (A) was used, a strange odor and wrinkles were generated, and the iron sliding property was almost equivalent to that of the blank. The same tendency as in Comparative Example 1 was observed when Comparative Example 2 in which the blending amount of component (A) was 50% by mass and Comparative Example 7 in which the blending amount of component (B) was 40% by mass were used. When the textile product processing article of Comparative Examples 3 to 5 in which any of the component (D), the component (E), and the component (C) was not blended, the generation of a strange odor could not be suppressed. Moreover, when the textiles processing article of the comparative example 6 which does not mix | blend (B) component was used, generation | occurrence | production of a strange odor could not fully be suppressed, iron sliding property was also bad, and water absorption was also bad.
