Abstract

  A wiping member comprising a ground yarn and a hydrophobic knitted knitted yarn is provided. A cleaning tool comprising a wiping member and a water absorbing member is also provided.

Description

  The present disclosure relates to a wiping member and a cleaning tool including the wiping member.

  Scraping products comprising wiping members formed by knitting yarns or one or more types of knitting yarns have been used to wash dishes, pans, pots, glasses, sinks or other kitchen utensils. Furthermore, scraped products comprising a wiping member and a water absorbing member such as polyurethane foam are also known.

  When cleaning dishes or other similar kitchen surfaces, consumers view foam as an indicator of cleaning power. At the same time, it is desirable to easily remove stubborn stains such as food stains, soap scum or oil stains.

  The present disclosure provides a wiping member comprising a ground yarn and a hydrophobic knitted knitted yarn, wherein the ground yarn and the hydrophobic knitted knitted yarn are knitted together to form a pile of the hydrophobic knitted knitted yarn. Furthermore, this indication provides the cleaning tool provided with a wiping member and a water absorption member.

The figure which shows one Embodiment of the wiping member of this indication. The figure which shows one Embodiment of the cleaning tool. The figure which shows another embodiment of the cleaning tool provided with the bag which consists of a wiping member.

  The wiping member 1 of the present disclosure includes a ground yarn 10 and a hydrophobic knitted knitted yarn 12. The ground yarn 10 and the hydrophobic knitted knitted yarn 12 are knitted together, whereby a pile of the hydrophobic knitted knitted yarn 12 can be formed on the surface of the wiping member. In some embodiments, the wiping member may include a flat yarn 14 that can be knitted into the ground yarn 10 so that a pile of flat yarns can also be formed on the surface of the wiping member.

  The ground yarn 10 of the present disclosure includes yarns that are commonly used in scraped or wiped products. Examples of the material of the ground yarn 10 include, but are not limited to, polypropylene, polyethylene terephthalate (PET), polystyrene, or nylon. The ground yarn may be a woolly yarn. Examples of the total fineness of the ground yarn include, but are not limited to, about 1000 g / m (10 dtex) to 20000 g / m (200 dtex). The ground yarn 10 may include a monofilament or a multifilament.

  The hydrophobic knitted knitted yarn 12 of the present disclosure includes a hydrophobic knitted knitted (KdK) yarn made of, for example, polypropylene, PET, or polystyrene. The KdK yarn 12 is a yarn having a fluffy texture and can be prepared, for example, by a known method such as unwinding the knit after first manufacturing. When a pile is formed on the surface of the wiping member 1 of the present disclosure, the KdK yarn 12 can provide a three-dimensional structure. The three-dimensional structure can provide more foam when the wiping member 1 is used with a detergent. In the present disclosure, more foam can be provided by forming a pile of hydrophobic KdK yarn on the surface of the wiping member 1.

  The total fineness of the KdK yarn 12 is, for example, about 1000 g / m (10 dtex) to about 100,000 g / m (1000 dtex), but is not limited thereto. The KdK yarn 12 may include monofilaments or multifilaments such as 1 filament (1F) to about 100 filaments (100F). The pile height of the KdK yarn 12 may be about 0.1 mm to about 10 mm, but is not limited thereto.

  The wiping member 1 of the present disclosure may further include a flat yarn 14. Examples of the flat yarn 14 include, but are not limited to, a plastic film such as a film made of polypropylene, PET, polystyrene, or the like. An example of the thickness of the flat yarn 14 may be about 20 μm to about 50 μm, and the width of the flat yarn 14 may be about 0.10 mm to about 10.0 mm. When the flat yarn forms a pile on the wiping member, the pile height may be from about 0.1 mm to about 10 mm. Examples of the weight per square meter of the wiping member include, but are not limited to, about 140 grams to about 1400 grams.

  The wiping member 1 of the present disclosure may be prepared by knitting the ground yarn 10 and the hydrophobic KdK yarn 12 together to form a pile of the hydrophobic KdK yarn 12 on the surface of the wiping member 1. When used, the flat yarn 14 may be knitted into the ground yarn 10 and a pile may be formed on the surface of the wiping member 1. For example, the wiping member 1 of the present disclosure may be prepared by applying a normal knitting method such as circular knitting. The pile of KdK yarn and / or flat yarn on the surface of the wiping member 1 may be a cut pile.

  In one embodiment, the cleaning tool 2 of the present disclosure includes the wiping member 1 and the water absorbing member 3 of the present disclosure. In some embodiments, the water-absorbing member 3 of the cleaning tool can be laminated to the wiping member 1 as shown in FIG. 2, or can be housed in the bag of the wiping member 1 as shown in FIG. . Examples of the water absorbing member 3 include, but are not limited to, plastic foam such as natural sponge, cellulose sponge, and polyurethane foam, woven fabric, or non-woven fabric.

  The cleaning tool 2 of the present disclosure can be prepared by laminating the wiping member 1 and the water absorbing member 3 using means known to those skilled in the art, such as bonding, ultrasonic waves, or suturing. Alternatively, the cleaning tool 2 of the present disclosure can be prepared by housing the water absorbing member 3 in the bag of the wiping member 1. The bag can be prepared by using a known method such as sewing or bonding the top and bottom of the cylindrical wiping member 1 made by circular knitting. The bag may be closed or may have an opening.

  The wiping member 1 or the cleaning tool 2 of the present disclosure can be used for cleaning, wiping, scraping, or wiping kitchen utensils. The wiping member 1 or the cleaning tool 2 of the present disclosure can be used alone, or can be used together with a detergent or soap in the form of a liquid, gel, powder or solid. The wiping member 1 or the cleaning tool 2 of the present disclosure has a pile of hydrophobic KdK yarns 12 so that more foam can be produced when a detergent or soap is used.

  In this specification, the following abbreviations may be used.

  KdK: knitted denit, PET: polyethylene terephthalate, PP: polypropylene

A sterilizable JOY solution (5 mL, P & G Japan kitchen detergent) with a foaming test concentration of 0.075 mL / L (water) was applied to the sample using a 5 mL syringe (without needle) manufactured by TERRUMO Corporation. Injected. Bubbles were formed using a vertical mixer (ASUD RUD-101). A vertical mixer was used 20 times at a rate of 36 times / minute. The foam volume was measured. The results are shown in Table 1.

Soap scum removal test Fatty acid calcium dispersed in isopropyl alcohol was uniformly applied to a stainless steel panel (JIS G4305 (SUS304) 2B). The alcohol was dried and heated on a hot plate for 2 minutes to obtain a test plate. Each sample obtained was then used to scratch the test plate by dragging the sample across the test plate while applying 130 grams of pressure with a finger. The results are shown in Table 1.
