- abrasive grains are bonded and fixed only to a surface layer of a nonwoven cloth with an adhesive agent. Accordingly, only the surface layer region to which the abrasive grains are bonded and fixed has an abrading power; at the same time when an adhesive agent layer is worn away, the abrasive grains are peeled off. Thus, the abrasive cloths have a problem that the abrading power falls rapidly.
- the nonwoven cloth is impregnated with a solution of a polyurethane resin or a polysulfone resin in a polar solvent having a high boiling point, such as dimethylformamide (DMF) and subsequently the DMF solvent is removed by using water or hot water; therefore, a troublesome step, such as distillation, is necessary to collect the solvent.
- a large amount of discharging water containing pollutants, such as BOD is generated so that a pollution problem may be caused.
- post-treatment of the discharging water is required.
- an object of the present invention is to provide a multipurpose cleaning cloth which makes it possible to clean stains adhering to the surface of an article to be cleaned effectively without use of a cleaner in the case of ordinary stains, or with a small amount of cleaner in the case of stubborn stains, without scratching the surface, by taking a structure itself of a nonwoven cloth into a unique consideration without bonding and fixing abrasive grains to fibers of the nonwoven cloth or a surface layer thereof or without forming a porous resin layer on fibers of the nonwoven cloth.
- the cleaning cloth according to the present invention is a cloth, in which a large number of parallel ridge regions each having a predetermined width are formed at predetermined intervals in a nonwoven cloth made of synthetic resin fibers each having a small diameter so that the fibers protrude in a loop by needle punching means.
- the thickness of regions in the nonwoven cloth, in which the ridge regions are not formed is from 1 to 3 mm
- the density of the nonwoven cloth is from 0.15 to 0.40 g/cm 3
- the height of the ridge regions is from 4 to 6 mm
- the interval between the ridge regions is from 4 to 8 mm
- the width of the ridge regions is from 3 to 6 mm.
- the synthetic resin fiber constituting the nonwoven cloth is a polyester fiber, and the fineness thereof is from 20 to 30 dtex.
- the invention has a constituent as described above, it is possible for edges of a large number of ridge regions arranged in parallel to each other to function as cleaning edges to improve a performance of cleaning the surface of an article to be cleaned. Further, since the ridge regions have the predetermined width, an appropriate strength of the ridge regions can be secured to restrain the quantity of compressive deformation (end face sagging) of the edge parts by a pushing-force during cleaning. Thus, a high cleaning performance can be kept. For example, in the case where the cleaning cloth is used while tableware or the like is washed with water, drainage is made good by grooves made between the individual ridges. Thus, the cleaning effect can be improved.
- the production process is simple and the cleaning cloth can be produced at low cost since the ridge regions can be effectively formed by needle punching using a nonwoven cloth as a base material. Additionally, since the ridge regions, which are substantially regions for a cleaning action, are integrated with the nonwoven cloth, there is an advantageous effect that the cleaning cloth is strong and has a long lifespan.
- ridge region edges at the middles grooves or at upper ends of the grooves also function as the cleaning edges to produce an effect that a higher cleaning performance can be obtained.
- a core material is polyester and a sheath material is polyethylene having a lower melting point than that of the core material
- the form of the ridge regions can be adjusted.
- synthetic resin fibers used in a nonwoven cloth are preferably polyester resin fibers since the fibers are firm and have abrasion resistance.
- the resin fibers each have a triangular or rectangular sectional shape and apexes thereof are made as sharp as possible, a preferable cleaning effect can be expected.
- Fig. 1 shows a nonwoven cloth, which is a base material of a cleaning cloth A according to the invention.
- This nonwoven cloth 1 is preferably made of polyester fibers having a fineness of 20 to 30 dtex, preferably 28 dtex, and a thickness (t) of 1 to 3 mm, preferably 1.5 mm.
- the density of the nonwoven cloth 1 is from 0.15 to 0.40 g/cm 3 , and is preferably 0.20 g/cm 3 . If the density is 0.15 g/cm 3 or less, the strength for keeping the shape deteriorates and further the effect of pulling out the fibers with the needle punch gets worse. If the density is more than 0.40 g/cm 3 , the needles are unfavorably damaged many times.
- the cleaning cloth of the invention is preferably a cleaning cloth wherein the height (h) of the ridge regions 2 is form 4 to 6 mm, preferably 5 mm, the width (Wl) of the ridge regions 3 is from 3 to 6 mm, preferably 4 mm, the interval between the ridge regions 2, that is, the width (W2) of the grooves 3 is from 4 to 8 mm, preferably 6 mm.

Abstract
Description
- The present invention relates to a cleaning cloth used to wipe off and clean stains adhering to glass, pottery, synthetic resins, metals, stone materials, and other various materials of tableware, rice cooling tools, utensils and others.
- Hitherto, as multipurpose cleaning cloths for households or industries, cloths formed from nonwoven cloth of synthetic resin fibers have been variously proposed, and used.
For example,Patent Document 1 discloses an abrasive cloth, wherein abrasive grains are bonded and fixed to the fiber surface of a nonwoven cloth containing synthetic fibers each having a flatness factor of 5 or more with a binder interposed therebetween.Patent Document 2 discloses an abrasive cloth, wherein silicon carbide abrasive grains are bonded and fixed to fibers of a nonwoven cloth containing a metal-plated synthetic resin fiber. Moreover,Patent Document 3 discloses an abrasive cloth, wherein a urea resin and silicon carbide abrasive grains are bonded and fixed to fibers of a nonwoven cloth. - Additionally,
Patent Documents - Further, Patent Documents 6 and 7 each disclose an abrasive cloth, wherein a porous resin layer is formed on fibers of a nonwoven cloth without using any abrasive grain.
Patent Document 1:JP-A-5-220670
Patent Document 2:JP-A-6-155310
Patent Document 3:JP-A-6-155311
Patent Document 4:JP-A-5-28477
Patent Document 5:JP-A-9-22886
Patent Document 6:JP-A-6-17374
Patent Document 7:JP-A-7-108465 - However, in the abrasive cloths disclosed in
Patent Documents 1 to 3, a thermoplastic resin is used as a binder to bond and fix abrasive grains to nonwoven cloth fibers. Thus, the friction between the abrasive grains and an article to be abraded or an article to be cleaned is large so that the lubricity is poor. As a result, it is unavoidable to use a cleaner or a lubricant separately. Additionally, the surface of the article to be cleaned, for example, tableware may be scratched since the hard abrasive grains are used. The abrasive cloths have such problems. - In the abrasive cloths disclosed in
Patent Documents - The abrasive cloths disclosed in Patent Documents 6 and 7, wherein a porous resin layer is formed on fibers of a nonwoven cloth, have a problem that the abrading power thereof cannot be exhibited unless an abrasive member containing abrasive grains is separately prepared to be simultaneously used. In a production process for forming the porous resin layer, the nonwoven cloth is impregnated with a solution of a polyurethane resin or a polysulfone resin in a polar solvent having a high boiling point, such as dimethylformamide (DMF) and subsequently the DMF solvent is removed by using water or hot water; therefore, a troublesome step, such as distillation, is necessary to collect the solvent. Furthermore, a large amount of discharging water containing pollutants, such as BOD, is generated so that a pollution problem may be caused. Thus, there also arises a problem that post-treatment of the discharging water is required.
- Therefore, an object of the present invention is to provide a multipurpose cleaning cloth which makes it possible to clean stains adhering to the surface of an article to be cleaned effectively without use of a cleaner in the case of ordinary stains, or with a small amount of cleaner in the case of stubborn stains, without scratching the surface, by taking a structure itself of a nonwoven cloth into a unique consideration without bonding and fixing abrasive grains to fibers of the nonwoven cloth or a surface layer thereof or without forming a porous resin layer on fibers of the nonwoven cloth.
- In order to attain the object, technical means described below are taken in the present invention. Accordingly, the cleaning cloth according to the present invention is a cloth, in which a large number of parallel ridge regions each having a predetermined width are formed at predetermined intervals in a nonwoven cloth made of synthetic resin fibers each having a small diameter so that the fibers protrude in a loop by needle punching means.
- When the invention is carried out, it is preferable that the thickness of regions in the nonwoven cloth, in which the ridge regions are not formed, is from 1 to 3 mm, the density of the nonwoven cloth is from 0.15 to 0.40 g/cm3, the height of the ridge regions is from 4 to 6 mm, the interval between the ridge regions is from 4 to 8 mm, and the width of the ridge regions is from 3 to 6 mm. It is also preferable that the synthetic resin fiber constituting the nonwoven cloth is a polyester fiber, and the fineness thereof is from 20 to 30 dtex.
- Since the invention has a constituent as described above, it is possible for edges of a large number of ridge regions arranged in parallel to each other to function as cleaning edges to improve a performance of cleaning the surface of an article to be cleaned. Further, since the ridge regions have the predetermined width, an appropriate strength of the ridge regions can be secured to restrain the quantity of compressive deformation (end face sagging) of the edge parts by a pushing-force during cleaning. Thus, a high cleaning performance can be kept. For example, in the case where the cleaning cloth is used while tableware or the like is washed with water, drainage is made good by grooves made between the individual ridges. Thus, the cleaning effect can be improved. Furthermore, the production process is simple and the cleaning cloth can be produced at low cost since the ridge regions can be effectively formed by needle punching using a nonwoven cloth as a base material. Additionally, since the ridge regions, which are substantially regions for a cleaning action, are integrated with the nonwoven cloth, there is an advantageous effect that the cleaning cloth is strong and has a long lifespan.
- As recited in
claim 3, by forming, in middles of the ridge regions, narrower middle grooves along a ridge direction in the invention, ridge region edges at the middles grooves or at upper ends of the grooves also function as the cleaning edges to produce an effect that a higher cleaning performance can be obtained. - As recited in
claim 5, by making the sectional shape of the synthetic resin fibers into a sharp cross section having different diameters, such as a triangle or a rectangle, in the invention, there is produced an effect that the cleaning performance is further promoted. - As recited in claim 6, when the synthetic resin fibers are formed to have a sheath/core structure, a core material is polyester and a sheath material is polyethylene having a lower melting point than that of the core material, it is possible to: form the ridge regions so that the fibers protrude by a needle punching manner in the production process for forming the ridge regions; and subsequently subject the resultant to heating treatment under the condition of a temperature, which is not higher than the melting point of the core material and causes the surface of the sheath material to be melted, thereby heating some parts of the fibers protruded toward the side of the ridge regions and intertwined with each other. As a result, the form of the ridge regions can be adjusted.

- When the invention is carried out, synthetic resin fibers used in a nonwoven cloth are preferably polyester resin fibers since the fibers are firm and have abrasion resistance. When the resin fibers each have a triangular or rectangular sectional shape and apexes thereof are made as sharp as possible, a preferable cleaning effect can be expected.
- Preferred embodiments for carrying out the invention will be described in detail hereinafter in accordance with the attached drawings.
Fig. 1 shows a nonwoven cloth, which is a base material of a cleaning cloth A according to the invention. Thisnonwoven cloth 1 is preferably made of polyester fibers having a fineness of 20 to 30 dtex, preferably 28 dtex, and a thickness (t) of 1 to 3 mm, preferably 1.5 mm. - In the invention, a large number of
parallel ridge regions 2 are formed withgrooves 3 interposed therebetween by protruding the fibers out by needle punching means, that is, punching a needle to the nonwoven cloth. In this case, the density of thenonwoven cloth 1 is from 0.15 to 0.40 g/cm3, and is preferably 0.20 g/cm3. If the density is 0.15 g/cm3 or less, the strength for keeping the shape deteriorates and further the effect of pulling out the fibers with the needle punch gets worse. If the density is more than 0.40 g/cm3, the needles are unfavorably damaged many times. - From results of cleaning performance tests, as illustrated in
Fig. 3 , the cleaning cloth of the invention is preferably a cleaning cloth wherein the height (h) of theridge regions 2 isform 4 to 6 mm, preferably 5 mm, the width (Wl) of theridge regions 3 is from 3 to 6 mm, preferably 4 mm, the interval between theridge regions 2, that is, the width (W2) of thegrooves 3 is from 4 to 8 mm, preferably 6 mm. - In the production process of the cleaning cloth of the invention, the
ridge regions 2 are formed so that a large number of fibers a protrude in a loop toward one of both surface sides thereof by needle punching means. As illustrated inFig. 1 , in this case, the needles are punched into thenonwoven cloth 1 along needle punching lines L having pairs of two adjacent lines L1 and L2, whereby theridge regions 2 having a predetermined width can be formed by using the fibers a protruded toward the single surface. When the interval between the individual pairs of the two lines L1 and L2 is changed, for example, when the interval is made slightly large, slenderimmediate grooves 4 can be formed along the ridge direction between theridge regions Figs. 2 and3 . - As illustrated in
Fig. 6 , theridge regions 2 having no intermediate grooves can be formed at intervals. - As described above, the
ridge regions 2 are formed, and subsequently the surfaces of the protruded fibers are subjected to heating treatment to be shrunken, thereby adjusting the form of theridge regions 2 and further improving the strength thereof. In this case, it is advisable that the fibers a are rendered fibers each having a triangular form and its apexes are made sharp, as illustrated inFig. 4(a) , or that the fibers a are made into a sheath/core structure, a core material c thereof is made of polyester, and a sheath material b thereof is made of polyethylene having a lower melting point than that of the core material c, as illustrated inFig. 4(b) . This manner makes it possible to deform some parts of the protruded and intertwined fibers a and a to adjust the form of theridge regions 2 by subjecting the fibers to heating treatment under the condition of a temperature, which is not higher than the melting point of the core material c and causes the surface of the sheath material b to be melted. The heating temperature in the heating treatment preferably ranges from 150 to 180°C. - The thus-formed cleaning cloth A of the first embodiment is a cleaning cloth, wherein the sectional shape of the individual fibers a, which constitute the cleaning cloth A, is made into a substantially equilateral triangle having sharp apexes. As illustrated in
Fig. 7 , therefore, stains such as hot water scurf and water scurf, and oily stains on tableware can be rubbed off with the sharp apexes of the individual fibers a. The stains rubbed off once can be floated and embraced into water held between the fibers. Thus, the stains are not again rubbed against the surface to be cleaned, so that stains can be effectively cleaned up only by water without using any cleaner. -
Figs. 8 and 9 illustrate a third embodiment.Fig. 8 is an enlarged view illustrating a sectional shape of a drawn monofilament made in the form of a substantial rectangle having projectedportions - About a nonwoven cloth made of such drawn monofilaments, which each have a sectional shape made into the form of a substantial rectangle, the monofilaments protrude in a loop by needle punching means, as in the first embodiment, to make ridge regions.
- As illustrated in
Fig. 9 , the thus-formed cleaning cloth also makes it possible to rub off stains such as hot water scurf and water scurf, and oily stains on tableware with thesharp apexes - As illustrated in
Figs. 4 and8 , in the invention, the sectional shape of the polyester fibers a is preferably made into a sectional shape having different diameters, which has sharp apexes, as in fibers a having a substantially triangular shape or fibers a having a rectangular shape. This makes it possible to promote the cleaning performance. - The cleaning cloth A of the invention may be used as it is in the state that the cloth is appropriately divided and cut into the form of sheets. Usually, as illustrated in
Figs. 3 and5 , a soft sponge support made of a foamed resin may be stuck on the lower surface of the cleaning cloth A so as to make the cloth into a cleaning tool. - The cleaning cloth of the invention can be used as a tool for cleaning articles in wide fields whether the articles are articles for households or industries in order to wipe off and clean stains adhering to the surface of glass, pottery, synthetic resins, metals, stone materials, and other various materials of tableware, rice cooling tools, utensils and others.
