Description

Cleaning sheet for textile products

The present invention relates to a wipe cleaning sheet for textile products.

BACKGROUND ART After washing, clothes are contaminated by stains such as food, sweat and sebum stains while wearing. When stains are attached to the garment being worn, it is often undressed after wearing and the undressed garment is washed with a washing machine. However, when stains such as food stains adhere to spots on clothes that are worn while going out, people often act with the stains attached, and people often feel uncomfortable. BACKGROUND ART A stain remover composition for a textile product is known to remove food-derived stains attached to the textile product.

For example, Japanese Patent Laid-Open No. 2003-105399 (Patent Document 1) discloses that when a stain removal agent composition containing a water-soluble organic solvent and a surfactant is used to remove stains on a fabric, a specific absorption A method for removing stains by applying a pad to a cloth is disclosed. In US Pat. No. 5,895,504 (Patent Document 2), stains attached to textiles and the like are wiped with a wipe impregnated with a cleaning agent containing a specific volatile organic solvent and a surfactant. Discloses a stain removal method for reducing ring fringing. Japanese Patent Publication No. 2008-511417 (Patent Document 3) contains an aggregating polymer, a non-volatile organic solvent, a detersive surfactant and water if necessary, and directly applies it to stains on spots on a cloth. A wipe that can be used is disclosed. In any of Patent Documents 1 to 3, a surfactant or an organic solvent is used as a stain removing component.

SUMMARY OF THE INVENTION A problem of the cleaning sheet impregnated with the stain remover composition for a textile product is a ring stain. The ring stain is a stain on the textile product when the detergent is used to remove stain components such as surfactant stains attached to the textile product or food stains attached to the textile product using a cleaning liquid. This is a phenomenon in which the cleaning liquid is extruded by the outermost portion and spreads concentrically around the soiled portion on the textile product to form a ring shape. However, the existing cleaning sheets are not sufficient to solve the problem of ring spots. The inventors of the present invention, when wiping off stains attached to a textile product using a cleaning sheet impregnated with a cleaning liquid, even if the degree of contamination of the soiled portion adhered to the textile product is reduced, due to the phenomenon of the ring stain. However, it has been found that there is a problem in that the stain spreads mainly on the stain portion, so that the thin stain spreads on the textile product and the stain area seems to have spread.

Further, as a problem of the stain removing composition, it is desired to further improve the cleaning property. Up to now, it has been attempted to further improve the detergency by optimizing the composition of the detergent composition. However, the present inventors have found that the detergency can be further enhanced by controlling the physical properties of the nonwoven fabric impregnated with the detergent composition.

That is, the present invention relates to a wipe cleaning sheet for a textile product, which is excellent in cleanability of a stain portion when a stain derived from food or the like attached to the textile product is wiped using a cleaning sheet impregnated with a cleaning liquid.

The present invention contains 0.3 mass% or more and 10 mass% or less of the following component (a1), 0.1 mass% or more and 5 mass% or less of the following component (b), and water, and contains the (a1) component. Amount of the cleaning agent composition having a mass ratio (a1)/(b) of the content of the component (b) of 0.6 or more and 50 or less, and a nonwoven fabric, wherein the cleaning agent composition with respect to the weight of the nonwoven fabric. It relates to a wiping and cleaning sheet for textile products, in which the mass ratio of the product is from 200 to 500 mass %. The following is the first aspect of the present invention.
Component (a1): One or more surfactants selected from nonionic surfactants and anionic surfactants (b) Component: Organic solvent having a hydroxyl group with ClogP of −2.0 or more and less than 1.0.

The present invention also contains a detergent composition containing (a2) a surfactant (hereinafter referred to as (a2) component) and water, and 50% by mass or more of one or more hydrophilic fibers, and has a flexural rigidity value of 0. The present invention relates to a wipe cleaning sheet for a textile product, which comprises a nonwoven fabric having a weight of 10 gf·cm ² /cm or more. The following is the second aspect of the present invention.

According to the first aspect of the present invention, when stains derived from food or the like attached to textile products are wiped off using a cleaning sheet impregnated with a cleaning liquid, not only can the degree of contamination of the soiled portion be reduced, Provided is a wipe-cleaning sheet for a textile product, which can reduce the diffusion of dirt around the dirt part.

Further, according to the second aspect of the present invention, when a stain derived from food or the like attached to a textile product is wiped off with a cleaning sheet impregnated with a cleaning liquid, the textile product is excellent in cleanability of the dirty portion.
