Description

SCRUBBING MEMBER AND CLEANING ARTICLE THEREOF}

The present invention relates to a scrubbing member and a cleaning article comprising the scrubbing member.

Scouring products, including scrubbing elements made of one or more types of knitted or woven yarn, may be used in dishes, pans, pots, glass, sinks or other kitchen utensils. It has been used to wash stuff. In addition, scouring products comprising scrubbing members and water-absorbing members, for example polyurethane foams, are also known.

When washing dishes or other similar kitchen surfaces, the consumer sees bubbles as an indication of cleaning power. At the same time, it is desirable to easily remove tough dirt, such as food stains, soap scum or greasy grime.

The present invention provides a scrubbing member comprising a foundation yarn and a hydrophobic knit-de-knit yarn, wherein the foundation yarn and the hydrophobic knit-de-knit yarn are knitted together to be hydrophobic A pile of knit-de-knit yarns is formed. In addition, the present invention provides a cleaning article comprising a scrubbing member and a water absorbing member.

The scrubbing member 1 of the present invention comprises a foundation yarn 10 and a hydrophobic knit-de-knit yarn 12. Foundation yarn 10 and hydrophobic knit-de-knit yarn 12 are knitted together, whereby a pile of hydrophobic knit-de-knit yarn 12 can be formed on the surface of the scrubbing member. In some embodiments, the scrubbing member can comprise a flat yarn 14, where the flat yarn 14 can be knitted into the foundation yarn 10, whereby the pile of flat yarn is also on the surface of the scrubbing member. Can be formed.

The foundation yarn 10 of the present invention includes yarns commonly used in scouring products or wiping products. Exemplary materials of the foundation yarn 10 include, but are not limited to, polypropylene, polyethylene terephthalate (PET), polystyrene, or nylon. The foundation yarn may be a woolly yarn. The total fineness of the foundation yarn includes, but is not limited to, for example, about 10 decitex to 200 decitex. Foundation yarn 10 may include mono filament or multi filament.

The hydrophobic knit-de-knit yarn 12 of the present invention comprises knit-de-knit (KdK) yarn made of hydrophobic yarns such as, for example, polypropylene, PET or polystyrene. KdK yarn 12 is a yarn with a fluffy texture, and can be produced by known methods, such as, for example, loosening after initial production of a knit. KdK yarn 12 can provide a three-dimensional structure when it makes a pile on the surface of the scrubbing member 1 of the present invention. The three-dimensional structure can also provide more foam when the scrubbing member 1 is used with a detergent. In the present invention, more foam can be provided by forming a hydrophobic KdK yarn pile on the surface of the scrubbing member 1.

The total fineness of KdK yarn 12 includes, but is not limited to, for example, from about 10 decitex to about 1000 decitex. KdK yarn 12 may comprise monofilament or multifilament, such as from one filament 1F to about 100 filaments 100F. The height of the pile of KdK yarn 12 may be from about 0.1 mm to about 10 mm, although not limited.

The scrubbing member 1 of the present invention may further comprise a flat yarn 14. Flat yarn 14 includes, but is not limited to, a plastic film such as, for example, a film made of polypropylene, PET, or polystyrene. Examples of the thickness of the flat yarn 14 can be from about 20 μm to about 50 μm, and the width of the flat yarn 14 can be from about 0.10 mm to about 10.0 mm. If the flat yarn makes a pile on the scrubbing member, the height of the pile may be from about 0.1 mm to about 10 mm. Examples of weight per square meter of the scrubbing member can be from about 140 g to about 1400 g, although not limited.

The scrubbing member 1 of the present invention can be produced by knitting the foundation yarn 10 and the hydrophobic KdK yarn 12 together to form a hydrophobic KdK yarn 12 pile on the surface of the scrubbing member 1. The flat yarn 14, if used, may be knitted onto the foundation yarn 10 and may form piles on the surface of the scrubbing member 1. Conventional knitting methods, such as circular knitting, for example, can be applied for the production of the scrubbing member 1 of the present invention. The pile of KdK yarn and / or flat yarn on the surface of the scrubbing member 1 may be a cut pile.

In one embodiment, the cleaning article 2 of the present invention comprises the scrubbing member 1 and the water absorbing member 3 of the present invention. In some embodiments, the water absorbent member 3 of the cleaning article may be laminated to the scrubbing member 1 as shown in FIG. 2 or included in the bag of the scrubbing member 1 as shown in FIG. 3. Can be. The water absorbent member 3 includes, for example, but is not limited to natural sponge, cellulose sponge, plastic foam, for example polyurethane foam, woven or nonwoven fabric.

The cleaning article 2 of the present invention can be produced by laminating the scrubbing member 1 and the water absorbing member 3 by means known to those skilled in the art such as, for example, attachment, ultrasonication or sewing. Alternatively, the cleaning article 2 of the present invention can be made by including the water absorbent member 3 in the bag of the scrubbing member 1. The bag can be produced by known methods, for example by sewing or attaching the top and bottom of the cylindrical scrubbing member 1 made by circular knitting. The bag may be closed or open-ended.

The scrubbing member 1 or cleaning article 2 of the present invention can be used for washing, scrubbing, scouring or wiping kitchen utensils. The scrubbing member 1 or cleaning article 2 of the present invention may be used alone or in combination with a detergent or soap such as liquid, gel, powder or solid. The scrubbing member 1 or cleaning article 2 of the present invention has a pile made by hydrophobic KdK yarn 12, so that more foam can be formed when detergent or soap is used.

In the present specification, the following abbreviations may be used.

KdK: Knitted-knit, PET: Polyethylene terephthalate, PP: Polypropylene

[Example]

Foam generation test

Terumo Corporation (without injection needle) circulating with a solution of Jokinnodekiru JOY (5 ml; kitchen detergent from P & G Japan) at a concentration of 0.075 ml / L (water) Was injected into the sample using a 5 ml syringe.
