Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaning wiping cloth for cleaning a body, a sink, a bathtub, and furnishings, and a cleaning tool using the same.
[0002]
[Prior art]
Conventionally, woven or non-woven fabrics made of ultra-fine fibers are used to dry and wipe fingerprints and oil stains on precious metals, tableware, furniture, automobiles, OA equipment, musical instruments, glass products, showcases, mirrors, etc. without using detergent. It is used as a cleaning tool for removal. On the other hand, in the washing of the body, wash basin, bathtub and furniture, the custom of using soap and detergent is persistent, and in the form of a knitted woven fabric or nonwoven fabric containing the above ultrafine fibers, soap or detergent may be applied. The foaming was poor, and the stain removability was not satisfactory.
[0003]
On the other hand, cleaning tools are commercially available in which a porous material such as an inexpensive soft urethane sponge is covered with a base fabric woven or woven with extra-fine fineness. Being a fiber, it has no effect on soil removal, i.e. such a coating does not actually make sense in terms of detergency. However, when using a sponge with an uncoated surface alone, an inexpensive soft urethane sponge is a polyester-based sponge, so that it is easily hydrolyzed, the strength is reduced, and partial destruction occurs in a short period of time. There was a problem that it often became unusable.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been developed in order to solve the problems at the time of cleaning the conventional body, wash basin, bath tub, and furniture as described above, and is more excellent in cleaning action and durability. To provide tools.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the inventor of the present application has intensively studied. As a result, the cleaning wiping cloth knitted into a bag shape with the molding yarn having the ultrafine fibers as the flower yarns covers the porous body made of the fiber aggregate having a predetermined relative density in a detachable state, so that It has been found that excellent cleaning properties can be achieved.
[0006]
That is, the present invention is a cleaning tool formed by detachably covering a porous body having a relative density of 0.05 or less with a cleaning wiping cloth made of a mall yarn having microfibers as a flower yarn, preferably The wiping cloth for cleaning described above, wherein the fineness of single fibers of the ultrafine fibers is 0.1 to 1.0 dtex, and a cleaning tool using the same. More preferably, the wiping cloth for cleaning is the above-mentioned cleaning tool having a bag shape, and more preferably, the above-described cleaning tool whose porous body is a fiber aggregate.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail.
The wiping cloth for cleaning according to the present invention is formed of a molding yarn having ultrafine fibers as a yarn, and is preferably formed in a bag shape. The mall yarn acts to enhance the foaming property of the surfactant contained in the detergent and the like, and has an effect of forming fine bubbles to enhance the washing property.
[0008]
The flower yarn forming the molding yarn of the present invention is composed of ultrafine fibers, and the fineness of the ultrafine fibers is preferably 0.1 to 1.0 dtex. If the single fiber fineness of the ultrafine fibers is less than 0.1 dtex, the single fibers are cut off at the time of wiping, leaving fluff on the surface to be cleaned. Conversely, if it exceeds 1.0 dtex, the wiping performance becomes insufficient. Preferably it is 0.2 to 0.5 dtex. In addition, the flower yarn preferably has a crimp, and more preferably has a false twist crimp, in that the wiping property is improved due to the disorder of the direction of the single fiber.
[0009]
The microfiber constituting the flower thread is a splittable conjugate fiber obtained by combining two or more types of mutually incompatible fiber-forming thermoplastic polymers, or is composed of an easily-eluting component and a hardly-eluting component. It is preferable to use a splittable conjugate fiber in which the easily eluted component is eluted and the hardly eluted component is divided into a plurality.
As the cross-sectional shape of such a splittable conjugate fiber, one generally known as a splittable conjugate fiber can be used, and the cross-sectional shape is a combination of various types such as a flat type, a petal type, a radial type, and a wedge type. can do.
In particular, in the present invention, a splittable conjugate fiber joined in a side-by-side type such that the cross section after splitting becomes flat is more preferable in terms of wiping properties.
[0010]
The method of dividing the splittable conjugate fiber is not particularly limited, and a method using chemicals, a method using false twisting, and a method using heat treatment can be adopted, and the so-called degree of division can be appropriately controlled.
[0011]
In addition, the flower yarn forming the molding yarn used for the wiping cloth for cleaning of the present invention has a height from the core yarn of 0.5 to 3 mm, preferably 1 to 2 mm. If the height is less than 0.5 mm or more than 3 mm, dirt attached to the concave portion cannot be wiped to all corners, resulting in poor cleaning performance.
[0012]
The fibers constituting the yarn used in the present invention are not particularly limited, and include polyester, nylon, polypropylene, vinylon, and ethylene-vinyl alcohol-based copolymer fibers. Preferably, it is particularly a splittable conjugate fiber containing nylon and / or polyester.
The fibers constituting the core yarn used in the present invention are not particularly limited, and include polyester and nylon. However, it is more preferable to use nylon from the viewpoint of adhesiveness.
[0013]
In the present invention, it is preferable that the yarn is gripped at a linear density of 7 to 15 yarns / cm. If the linear density is less than 7 lines / cm, the degree of adhesion to the object to be cleaned is reduced and the wiping property is deteriorated. On the other hand, if the linear density exceeds 15 yarns / cm, the processing speed becomes extremely low in manufacturing the molding yarn, which is disadvantageous in cost. The linear density is set according to the conditions at the time of manufacturing the molding.
[0014]
Most of the bulk of the mall yarn used in the cleaning wiping cloth of the present invention is occupied by the flower yarn, and the cleaning performance is deeply influenced by the state of the ultrafine fibers which are constituent fibers. Therefore, the fineness of the molding yarn is not particularly limited, and can be appropriately set.
[0015]
In the production of the molding yarn according to the present invention, for example, while supplying a plurality of core yarns (some of them may be used as adhesive fibers for bonding the yarns) to a molding twisting machine, a flower is wound around the core yarns. Wrap the yarn and then twist the yarn while cutting the flower yarn wound with a cutter to form a molding yarn.When using an adhesive fiber, heat-treat at a temperature at which the adhesive fiber melts after forming the molding yarn. It is intended to provide a molding yarn in which the yarn is prevented from falling off from the core yarn by bonding and fixing the core yarn and the yarn, but the present invention is not limited to such a method for producing the molding yarn, and other For example, the molding yarn may be manufactured by using the Raschel method or the tricot method, and the manufacturing method is not particularly limited.
The molding yarn used in the present invention can be kept clean by applying a bacteriostatic treatment and an antibacterial treatment to prevent a bad smell and prevent propagation of bacteria and the like.
[0016]
Further, the cleaning tool of the present invention is characterized in that the cleaning wiping cloth covers the porous body in a detachable state. The detachable state is necessary in that only the cleaning wiping cloth can be kept clean by washing. For this purpose, the cleaning wiping cloth is preferably formed in a bag shape. A tubular knitting machine or a glove knitting machine can be suitably used as a method for forming a bag. A rubber thread may be inserted into the opening using the glove knitting machine, or fraying may be prevented by sewing. The form of the bag is not particularly limited, and may be any shape as long as the porous body can be inserted.
Further, the surface structure of the wiping cloth for cleaning may have a pile structure, or may have a sheet fabric, a fawn structure, or a mesh structure, and is not particularly limited.
[0017]
In the present invention, the porous body is used by inserting it into a bag-like wiping cloth for cleaning, and the porous body has a function of a foaming generation unit for forming a foam at the same time as a storage unit for an aqueous solution of soap and detergent. Things.
A typical example of such a porous body is a urethane sponge.However, when the urethane sponge is a porous material having closed pores, the foamability after washing is poor. Therefore, urethane sponges preferably have open pores because of the problem that harmful bacteria propagate in the sponge. However, soft urethane sponges used for ordinary cleaning are inexpensive polyester-based urethanes, so that they are easily hydrolyzed and have poor durability.
Therefore, the porous body to be inserted in the present invention is preferably a fiber assembly having structurally open pores as typified by a dry nonwoven fabric.
[0018]
Next, in order to ensure foaming properties, it is important that the relative density of the porous body is 0.05 or less. If it exceeds 0.05, it will have a hardened structure, and it will not easily deform with a thick porous body, which will impair the foaming properties of soap or detergent. Preferably it is 0.03 or less.
The relative density is determined by dividing the apparent specific gravity of the porous body by the specific gravity of the constituent components.
[0019]

【The invention's effect】
According to the present invention, a wiping cloth for cleaning, which is formed by knitting a molding yarn having ultrafine fibers as a flower yarn in a bag shape in washing a body, a sink, a bathtub, and a furnishing using soap or a detergent, has a relative density of 0. Since the cleaning tool has a structure in which it is detachably coated on a porous body of not more than 05, the foaming property is high, and an excellent cleaning effect can be exhibited because it is an ultrafine fiber. Further, when the porous body is a fiber aggregate, the bubble elimination property is better, and it is possible to remove the cleaning wiping cloth and keep it clean by washing.
Further, even if the porous body is no longer required, the porous body is a fiber aggregate, and if the relative density is 0.05 or less, the porous body is covered with a wiping cloth for cleaning. Thus, it can be used as the cleaning tool of the present invention, and can contribute to reduce, reuse, and recycle.
