Description

  The present invention relates to a wiping fabric having a cut pile yarn containing a split split type composite fiber and a floor cleaning tool using the same.

  For floor cleaning for business use, what is normally used to remove dirt on the floor, such as earth and sand, cotton dust, and hair, is typically a disposable nonwoven duster cloth or a cloth that can be used repeatedly by washing. is there. In general, these cloths are usually mounted on a special holder with a long handle and used for cleaning. In particular, reusable cloth is highly durable and economical, and has the advantage of being usable not only for dry dusting, but also for wiping water and dampening. Is widely used.

  Reusable cleaning cloth with high dirt removal effect includes split-type pile fine knitted fabric and non-woven fabric containing split ultrafine composite fibers (more than 50% of fibers with split single fiber fineness of 0.5 decitex or less) Patent Document 1 discloses a cleaning cloth having a two-layer structure in which two layers are bonded and integrated. According to this document, by using the divided ultrafine fibers, the effect of wiping off the dirt is enhanced, and by making the pile woven fabric side into a scissors shape, relatively large dust and a large amount of dust are removed. The function can be improved.

  However, it is composed of a pile made of ultrafine fibers having a single fiber fineness of 0.5 dtex or less as described above, and in particular, in a mop having a high density pile fabric, the floor (to be cleaned) There is a problem in that the frictional resistance to the surface) is large and a strong force is required during work. In particular, in the field of commercial cleaning, it is necessary to clean a floor with a large area in a short time, and therefore it is desirable to be able to work efficiently with a lighter force. Patent Document 2 discloses a contrivance that reduces the force required for water wiping work by changing a fine stitch pattern such as a cleaning knitting picket using microfiber, deer knitting, and honeycomb pattern. However, as described above, the raised pile structure using ultrafine fibers has a very high wiping property, but this document does not disclose the raised pile structure.

JP-A-5-192284 WO02 / 084002 specification

  An object of the present invention is to provide a wiping cloth having a cut pile structure that has a high wiping effect, has a low resistance during wiping, and can be efficiently operated with a light force, and a cleaning tool using the cloth. To do.

  As one aspect, the present invention has a cut pile yarn containing a peelable split type composite fiber on the ground structure, and a region where the cut pile yarn is present and a region where the cut pile yarn is not present are band-shaped. A cloth for wiping formed alternately, wherein the peelable split composite fibers constituting the cut pile yarn are split split into 3 to 20 single fibers, and the split split composite The single fiber fineness after fiber splitting is 0.01 to 0.5 dtex (dTex), and the cut pile density before splitting of the split splitting composite fiber is 7000 to 20000 per 6.45 square centimeters, However, a cloth for wiping is provided in which the cut pile density is a density relative to the area of the entire wiping surface.

  With the configuration of the present invention, it is possible to work efficiently with a light force even when wet, while maintaining the high wiping property of the cut pile structure.

  In the present invention, the fibers constituting the cut pile yarn are those obtained by separating and separating the separation split type composite fibers. By being separated by separation, the contact area between the wiping surface and the fiber is increased, and the wiping property is improved. On the other hand, since the contact area between the wiping surface and the fiber is increased, the frictional force generated during the wiping operation is increased, and the working efficiency is lowered. In the wiping fabric of the present invention, regions where cut pile yarns are present and regions where the cut pile yarns are not present are alternately formed in a strip shape. This makes it possible to reduce the force required for work without reducing the wiping property.

  The cut pile yarn constituting the wiping surface of the wiping cloth preferably has crimps in order to capture dust efficiently. The above-mentioned “separated and separated fibers” can be achieved by adjusting the degree of crimping brought about during crimping processing. Generally, when the crimp rate is less than 10%, the splitting of the composite fiber does not substantially proceed, and the trapping action or wiping action is not effective. For this reason, the crimping process is preferably performed with a crimp rate of 10% or more. FIG. 1 shows a schematic cross-sectional view of a separation-separated composite fiber before separation. FIG. 2 shows a schematic cross-sectional view of a separation-separated composite fiber after separation treatment {cross-sectional view in a completely separated state ( a) and sectional view (b)} in a state where a part of the composite fiber constituting layer is divided are shown.

Said crimp provision process can be performed by the false twist method, for example. Peeling and splitting of the peelable split composite fiber is performed by false twisting. Since the separation division proceeds by increasing the set false twist number during false twisting, the fiber division can be adjusted by controlling the set false twist number. In general, the conditions for obtaining fibers suitable for the present invention can be set based on the standard false twist number described in the following formula.
Standard false twist number = 2500 × (165 / fineness of multifilament to be false twist) ^0.5
(Wherein the fineness is in decitex units).
In the above formula, when a standard false twist number is used, a completely divided fiber is usually obtained. In the present invention, in order to obtain a divided fiber, it is preferably 80% or more of the standard false twist. In this way, a fiber having only the cross-sectional shape (a) described above or a mixture of the cross-sectional shapes (a) and (b) in the fiber is obtained.

  The composite fiber constituting the cut pile yarn exposed on the wiping surface of the wiping cloth of the present invention is obtained by separating and dividing a fiber that can be divided into 3 to 20 single fibers, and the single fiber fineness is 0.01 dtex or more. Less than 0.5 dtex. Note that the single fiber fineness is 0.01 dtex or more and less than 0.5 dtex, in general, the ultrafine fiber fineness that can be achieved when the composite fiber is almost completely divided (FIG. 2 (a)). Correspond. The wiping fabric of the present invention is mainly composed of fibers separated and separated, but may contain undivided fibers or partially divided fibers as long as the soil removability is not excessively lowered.

  As described above, in the wiping fabric of the present invention, regions where cut pile yarns are present and regions where the cut pile yarns are not present are alternately formed in a strip shape. This makes it possible to reduce the force required for work without reducing the wiping property. In the present invention, the cut pile density before separation of the peelable split composite fibers is 7000 to 20000 per 6.45 square centimeters as the density with respect to the area of the entire wiping surface. For this reason, for example, in the case of having 6200 cut pile yarns per 6.45 square centimeters, the area of the region where the cut pile yarns exist is 0.11 to 0.33 with respect to the entire area. It becomes. If the area where the cut pile yarn is present is larger than this, the frictional force becomes too large, particularly the wet frictional force becomes too large, and the working efficiency is lowered. On the other hand, if the area where the cut pile yarn is present is smaller than this, the dirt cannot be sufficiently removed. Thus, if the area where the cut pile yarn is present is X millimeter wide, the area where the cut pile yarn is not present can have a width in the range of about 2.1X to 7.7X millimeters, for example, cut pile When the width X of the region where the yarn is present is 3 mm, the width of the region where the cut pile yarn is not present can be 6.2 to 23.2 mm. In addition, the density of the cut pile yarn in the region where the cut pile yarn is present is usually 30000 to 80000 pieces per 6.45 square centimeters. The above number refers to the number of separation-split fibers in a state before the splitting process that constitutes the cut pile yarn standing from the ground structure, and this is organized as a cut pile yarn from the back side of the wiping fabric. This is equivalent to counting the number of exfoliated split-type composite fibers in the state before split processing in cut pile yarns standing through the ground structure.

  The length of the cut pile yarn (the length from the ground structure to the tip of the cut pile yarn) is not limited, but is usually 2 to 10 mm, preferably 3 to 9 mm, more preferably 5 ~ 8mm. If the length of the cut pile yarn is too short, the effect of removing dirt becomes low. If it is too long, the force required for the work may be too high.

  The exfoliation division type composite fiber used in the present invention is not particularly limited. For example, there are a multi-layer lamination type and a radial division type, but there is a Sophistor lamp (trade name) (made by Kuraray Co., Ltd.).

  In a preferred embodiment of the present invention, a fiber yarn having a loop group composed of synthetic fiber filaments on the back surface is knitted as part of the ground yarn to have an engaging function, and the loop group is exposed to expose the surface. It can function as a fastener loop material. That is, in the attachment with the holder provided with the hook-and-loop fastener material, a separate process for newly attaching the hook-and-loop fastener material separately is not required, and the cost can be reduced.

  In relation to this, in order to rationalize the assembly method of skin materials such as automobile interior materials, chair upholstery, etc., and to express the function as a hook-and-loop loop material for the purpose of unifying the materials, Japanese Laid-Open Patent Publication No. 10-77553 proposes a double knitted fabric in which fiber yarns having loop groups are knitted and integrated on the back surface side so as not to affect the surface even when the surface fastener hook material is attached or detached. Yes. In the present invention, the above technique can also be used effectively, that is, the fiber yarn having a loop is cut pile so that the cut pile surface is not affected even when the hook is attached to or detached from the holder. Although it is important in terms of consumption performance to knit into the ground tissue to be grasped, the same technical technique cannot be used in terms of organization. That is, in the conventional circular knitted cut pile manufacturing method, since the yarn forming the cut pile is exposed on the back surface, the yarn forming the cut pile can be formed by simply knitting the fiber yarn having the loop group as the ground yarn. Since it is covered by the stripe, the loop function does not appear. For this reason, in order to provide an engagement function, the following new devices are required.

  In order to make the fiber yarn having the loop group function as a surface fastener loop material, it is important to expose only the fiber yarn on the back surface of the wiping fabric. Woven fabrics, circular knitted fabrics, warp knitted fabrics, and tufted fabrics are known as fabrics having cut piles. In the present invention, it is preferable to use circular knitted fabrics in terms of high degree of freedom in production. In addition, production by pile weaving is preferable in that the shape stability of the fabric is excellent. However, in conventional circular knitted fabrics, in particular, sinker pile knitted fabrics, the cut pile yarn is exposed on the back surface, so that the engagement function is not exhibited even if fiber yarns having loop groups are used as the ground yarn. Therefore, it is possible to expose only the fiber yarn having the loop group on the back surface by erecting the cut pile yarn by the tack structure.

  As the fiber yarn having the loop group, for example, a design twisted yarn or a product obtained by a fluid turbulent flow processing method can be considered, but the fluid turbulent flow processing method is preferable in terms of productivity. More specifically, a fiber yarn having a loop group can be manufactured by a conventional method using a Taslan (registered trademark of Hebaline Fiber Technology Inc.) nozzle. It is necessary to find the optimization condition in consideration of the above points. When the obtained loop size is too large and / or the number per unit length is too large, the unwinding property of the wound fiber yarn is deteriorated, and the tension fluctuation when fed to the knitting machine is reduced. Since it becomes large, it leads to an increase in wrinkle generation on the dough. As for the engagement property, since there is a relationship with the shape, size, density, etc. of the hook-and-loop fastener material, it is preferable to individually optimize the relationship with the above-described process passability.

  In addition, the form of the fiber yarn to be used is that the loop is formed regardless of whether the crimp is applied or not, but the fiber forming the loop in the hooking to the loop to the hook-and-loop fastener material. Since it is preferable that the yarn is split, a crimped yarn in which voids are easily formed is more preferable than a non-crimped fiber yarn having a uniform yarn, more preferably a low crimp. Use false twisted yarn. Furthermore, the strength of the fiber yarn forming the loop cannot be uniquely determined because of the relationship with the hook-and-loop hook material. However, according to the knowledge so far, if it is 4 cN / dTex or more, there is a problem in durability. There are few things.

  Although it described regarding the suitable aspect of the cloth for wiping which has an engagement function of this invention, the improvement of wiping performance and maintenance property can be aimed at by the device described below.

  The objects to be wiped by the wiping fabric according to the present invention include rough dust such as dust, dust, moisture, hair, sand, paper pieces, and wood pieces, oil, etc., but the wiping property is a basic requirement for wiping fabrics. It is very important to improve this. Below, it describes about the fiber which can be used for the cut pile yarn which comprises the wiping surface of the cloth for wiping of this invention. Since the wiping surface after wiping off the oil is firmly attached to the fibers, it is difficult to wash the wiping fabric after use by washing work, and even a skilled professional needs time. Cost. It is known that the oil content removal performance of an ultrafine fiber greatly depends on its cross-sectional shape, and that having an edge shape is advantageous. The oil removing mechanism is explained by physical scraping and entanglement between fibers. However, there is a chemical interaction between the oil adhering to the fiber and the fiber, and depending on the type of the fiber-forming polymer, the fiber is difficult to remove even in the washing operation, which is a mechanical stagnation operation and a soil removal operation using a surfactant. There are types. The oil removal property by washing operation is better for hydrophilic fibers than for hydrophobic fibers. Typical examples of hydrophobic fibers are polyester, nylon, acrylic and acrylic, polyolefin, and polyvinylidene chloride fibers, and hydrophilic fibers include fibers made of cellulosic fibers, polyvinyl alcohol, and copolymers thereof. Although the fiber which consists of polyvinyl alcohol and its copolymer is preferable at the point of fiber strength, a polyvinyl alcohol copolymer is more preferable at the point which can provide a crimp, and the point from which a peelable split type fiber is obtained.

  For this reason, as a fiber which comprises the cut pile thread | yarn which comprises a wiping surface, the peeling division | segmentation type | mold composite fiber comprised from the phase which consists of an ethylene-vinyl alcohol copolymer and the phase which consists of another thermoplastic polymer is preferable. The oil-removing property by washing operation is superior to that of peelable split fiber made of polyester or polyester and nylon. Preferable exfoliation split type composite fibers include composite fibers composed of a phase composed of an ethylene-vinyl alcohol copolymer and a phase composed of polyester.

  In addition, it is also important to impart durability to the hardness of the fabric in order to prevent the fabric from wrinkling due to repeated washing and the mounting property of the cleaning tool to the base (holder) from being deteriorated. . In order to achieve this, together with the fiber yarn having the loop group, a polyester false twist yarn or the like is knitted into the ground structure as a ground yarn.

  In order to improve the bondability between the above-mentioned ground yarns, it is possible to improve durability by using a heat-sealing fiber as the ground yarn instead of the polyester false twisted yarn. In order to prevent the loop group exposed on the back surface from being affected, the use form of the heat-bonding fiber has the cut-pile yarn and the loop group for the stitch that holds the cut-pile yarn. Set to exist in the middle of the fiber yarn. A secondary effect of including the fused fiber is to prevent the pile yarn from fraying.

  A core-sheath composite fiber configured so that the softening temperature of the sheath component is 40 ° C. or more lower than the softening temperature of the core component is usually used as the heat-bonding fiber that can be used. Therefore, a core-sheath composite fiber having a relatively high melting point ethylene-vinyl alcohol copolymer as a sheath component is preferable because false twisting can be performed. In addition, how to arrange the cut pile yarn also affects wiping and maintenance, and the structure that completely covers the surface reduces the wiping property and at the same time increases the frictional force with the surface to be wiped. Therefore, it is not preferable in that it increases the load on the operator, and also in terms of washing operation, the maintenance of the oil content that is entangled up to the root of the cut pile yarn is significantly reduced. .

  In the case of the above pile density range, the height of the cut pile yarn from the ground structure is preferably 2 mm or more and 10 mm or less. The height of the cut pile yarn affects the degree of freedom of the cut pile yarn, and if it is less than 2 mm, the degree of freedom is reduced and good wiping property cannot be obtained, and if it exceeds 10 mm, the wiping property is reduced. However, there is a possibility that the cleaning performance in the washing operation is remarkably lowered and the cost is increased at the same time. Therefore, the height of the cut pile yarn from the ground structure is preferably 3 to 9 mm, more preferably about 5 to 8 mm.

  In addition to the requirements for wiping and maintenance as described above, the direction of mounting on the base (holder) of a cleaning tool such as a mop affects the wiping property. In a wiping fabric in which regions where cut pile yarns are present and regions where cut pile yarns are not present are alternately formed in a strip shape, the longitudinal direction of the strips is arranged parallel to the wiping operation direction. Since the wiping action is substantially lost in the belt-like portion in the region where the cut pile yarn does not exist, the wiping property is deteriorated. Therefore, it is desirable that the band is arranged so that the longitudinal direction thereof is 30 ° or more with respect to the wiping operation direction, and most preferably 90 ° (that is, perpendicular). More specifically, although the base (holder) of the cleaning tool is generally rectangular, it is mounted so that the angle formed between the cut pile row and the long side is 60 ° or less. The angle formed with the long side can be adjusted by changing the cutting method. However, in order to easily cause a sewing loss, it is preferable to form it systematically at the stage of manufacturing the knitted fabric.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 3 shows a schematic cross-sectional view of the wiping fabric of the present invention. The cut pile yarn 1 is gripped and erected by a ground structure 4 including a ground yarn 2 including fiber yarns 3 having loop groups.
The fiber yarn 3 having the loop group is exposed on the surface opposite to the cut pile yarn 1. The ground yarn 2 including the fiber yarn 3 having a loop group is preferably knitted with a heat-sealing fiber. The heat-sealing fiber can heat-bond the ground yarns 2 constituting the ground structure by heat treatment to reinforce the ground texture, and can fix the cut pile yarn to improve the washing resistance.

  FIG. 4 shows a partially enlarged schematic view of the cut pile yarn 1 of the wiping fabric of the present invention. The cut pile yarn 1 includes a peelable split type composite fiber, and is generally formed from the split states (l) to (p). The cut pile yarn mainly shows a divided state (l) (completely divided state), but is not limited to this, and a partially divided state (divided state (n) is divided as if branched) The split state (o) is a state in which only the tip is almost completely split, the split state (p) is a state in which a part of the composite fiber constituting layer is peeled off, and the split state (m) is almost split. May be included).

  FIG. 5 shows a schematic diagram of a fiber yarn 3 having a loop group used in the present invention. The fiber yarns 3 having loop groups are preferably formed by fluid turbulent processing, and a large number of loops 5 having different sizes are formed. However, if the number of loops 5 per unit length is too large and / or too large, Since it becomes a problem in a knitting process, it is preferable to adjust in relation to the hook-and-loop fastener material to be engaged.

  FIG. 6 shows an example of a knitting structure chart for knitting the wiping fabric of the present invention. Cut pile yarn is inserted into the yarn feeders (A) and (D), and fiber yarns having a loop group are added to the yarn feeders (B) and (C). Insert the ground yarn that contains it. The yarn is not supplied at the yarn feeders (C) and (F), and the cut pile yarn is cut by the cylinder needle to form the cut pile on the knitting machine. It is important in the manufacturing method to install a yarn lifting prevention tool between the yarn feeders (A) and (B) and (D) and (E), and (B), (C) and (E) It is to install a yarn lifting prevention tool during (F).

  FIG. 7 shows a structure in which regions where cut pile yarns exist, that is, cut pile texture rows and regions where cut pile yarns do not exist, ie, tissue rows containing only the ground texture, alternately exist in a band shape. FIG. A state in which the cut pile tissue rows 6 and the tissue rows 7 only of the ground tissue are alternately formed is shown. With such a structure, the force required for the wiping operation during work can be reduced. Further, the dirt adhering to the cut pile yarn can be effectively removed during the washing operation because the entanglement of the cut pile yarn can be suppressed to some extent. Furthermore, the time required for drying is shortened as compared with the case where the cut pile yarn is arranged on the entire surface.

  FIG. 8 is an exploded perspective view of a mop in which the wiping fabric of the present invention is engaged and mounted on a handle base (holder) provided with a hook-and-loop fastener material. The wiping fabric 8 of the present invention is mounted on the handle base 9 to constitute a mop 10. The state where the strip-shaped portion of the cut pile structure row 6 is parallel to the longitudinal direction of the handle base 9 is shown. The mop 10 is used for wiping the floor surface, wall surface or ceiling surface.

  As described above, the wiping fabric of the present invention has been described with respect to the wiping fabric having a loop group on the back surface, which can be engaged with a base with a handle provided with a hook-and-loop fastener material to form a mop. The wiping fabric of the invention is not limited to one having a loop group on the back surface, and it is not necessary to have an engaging means on the back surface of the fabric. A base with a handle that can hold a fabric having no engagement means on the back surface is described in, for example, U.S. Pat. No. 4,225,998 and JP-A-10-314096. 9 and 10 are perspective views of a mop using such a patterned base. In FIG. 9, the wiping fabric 8 is fixed to the base 9 with a clip-like stopper 11 to form a mop 10. In FIG. 10, the wiping fabric 8 is fixed to the base 9 by inserting a part of the fabric into the stopper 11 with a hole, and the mop 10 is formed. A perspective view of a wiping fabric useful for these mops is shown in FIG. In FIG. 11, the wiping fabric 8 has only a region on the wiping surface 12 in which regions where cut pile yarns exist and regions where cut pile yarns do not exist are formed in a strip shape. The both ends 13 of this have no cut pile yarn. Such a fabric is designed such that both ends 13 are fixed at the stopper 11 portions of FIGS.

  Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

Examples 1-4 and Comparative Examples 1-2
A circular knitting machine was used to produce a knitted fabric with a stripe pattern in which pile yarn regions shown in Table 1 and regions where pile yarns exist and regions where pile yarns do not exist are alternately arranged in a band shape. The pile was a cut pile. As a control, a knitted fabric having pile yarn on the entire surface was also produced.

  More specifically, as a pile yarn, Sophistor lamp (trade name) (manufactured by Kuraray Co., Ltd.) was used. It has the following configuration. Six layers of polyethylene terephthalate obtained by melt spinning a polyethylene terephthalate and a saponified ethylene vinyl acetate copolymer having a degree of saponification of 99% and an ethylene content of 48% by mole in a ratio of 2: 1 and ethylene vinyl acetate A multifilament of 100 decitex / 24 filaments is obtained by drawing a composite fiber having a flat cross section that can be peeled and split into 11 having 5 polymer layers, and false twisted to separate and split. As a result, a processed yarn having a single fiber fineness of 0.2 to 0.3 dtex is obtained. A blended yarn obtained by combining five such processed yarns is used as a cut pile yarn (100 dtex / 24 filament × 5 bundles).

A knitted fabric was formed from the cut pile yarn and a ground yarn containing a polyester false twist yarn. The length of the cut pile yarn (the length from the ground structure to the tip of the cut pile yarn) was 6.5 mm. In addition, the number of composite fibers constituting the cut pile yarn was 61,200 per 6.45 cm ² (as the number before the split separation).

Comparative Examples 3 and 4
In Comparative Example 3, the Sophie Star lamp (trade name) used in Examples 1 to 4 (100 dtex / 24 filament × 3 bundle) and 3 dtex polyethylene terephthalate (PET) (75 dtex / 25 filament × 4 bundle) were used. The yarn mixed with was cut pile yarn (Sofister lamp: PET = 50: 50). In Comparative Example 4, 3 dtex polyethylene terephthalate (75 dtex / 25 filament x 1 bundle) was added to the Sophistor lamp (trade name) (100 dtex / 24 filament x 3 bundle) used in Examples 1-4. The mixed yarn was used as a cut pile yarn (Sofister lamp: PET = 80: 20).

The following evaluation was performed using the wiping fabric produced as described above.
Evaluation 1: Evaluation of dirt removal effect A long sheet made of vinyl chloride in which the fabric of each example is attached to a duster holder with a long handle (Muster Duster Holder M size manufactured by Sumitomo 3M Co., Ltd.) and sprayed with a constant weight of standard dirt ( Sumitomo 3M Dynoch Film) was pressed over a certain distance for cleaning. As standard soil samples, soil dust (standard soil powder (true density about 3.0 g / cm ² , average particle size about 30 μm, soil powder mainly composed of SiO ₂ , Al ₂ O ₃ )), cotton dust ( Cotton linter) and sand were used. The dimension of the fabric was 165 mm (width) × 670 mm (length). The direction of the band in which the region where the pile yarn is present and the region where the pile yarn is not present is alternately extended in the length direction. Using such a duster, the weight of the removed dirt was measured, and whether it was difficult to remove the dirt with respect to the first spread dirt was used as a measure of the dirt removing effect. The results are shown in Table 2.

  From the above results, Examples 1 to 4 having a narrow stripe width have substantially the same removal efficiency as the control fabric having the entire pile yarn, but Comparative Examples 1 and 2 having a large stripe width have soil and cotton dust. It can be seen that the removal rate is low. Further, in Comparative Examples 3 and 4 using yarns mixed with PET fibers having a large fiber diameter, the removal efficiency is lowered. Accordingly, the fiber used as the pile yarn has a higher removal efficiency as the proportion of the ultrafine fiber having a smaller single fiber fineness is larger.

Evaluation 2: Force required for work The fabric was mounted on the same duster holder, and the fabric was pushed in both a dry state and a wet state, and the maximum value of the force required at that time was measured. In the wet state, the product was washed for 2 minutes in a washing machine and then dehydrated for 2 minutes. The force at the time of pushing was measured on a P tile coated with resin wax. An indenter of a torque gauge (Iko Engineering CPU gauge) was fixed to the tip of the handle of the holder, and the force when pushed was measured. The results are shown in Table 3 below.

  From Table 3, when wet, in the control example (fabric in which the entire surface pile is present), the force required for pushing exceeded 1 kg weight, which was considerably difficult to work, but in the stripes of Examples 1-4. It has been found that the fabric of the present invention in which pile yarn is present can be effectively operated with a sufficiently light force even in a wet state.

Evaluation 3: Evaluation of the speed of drying at the time of washing Using the control example, the fabric and the fabric of Example 2, the speed of drying at the time of washing was evaluated. First, after washing with a washing machine for 2 minutes, the fabric dehydrated for 2 minutes was kept in a constant temperature and humidity oven at a temperature of 20 ° C. and a relative humidity of 90%, and the amount of water contained in the fabric was measured. Immediately after dehydration, the drying time was 0 h, and the weight of the fabric was measured every 1 h to determine the amount of water contained in the fabric. A fabric having a structure of 150 mm width × 670 mm length and a base portion (a portion without PET brush raising) each having a width of 60 mm was used at both ends in the width direction. The results are shown in Table 4 below.

  From the above results, it is shown that the moisture content after dehydration is smaller when the pile density is smaller and drying is faster.

  From the above results, it was found that the fabric of the present invention has sufficient dirt removal performance, low work force required, good workability, and fast drying during washing.

  The wiping fabric of the present invention is pushed and cleaned in the form of a mop attached to a duster holder, so that the floors of office buildings, schools, hospitals, retail stores, supermarkets and other stores (dust, earth, sand, cotton, hair, dust, Oil) and the like can be effectively removed by the fine fiber pile. Since the wiping cloth of the present invention is made of a durable woven material, it can be selected and used repeatedly and is economical. Since it has a striped (striped) pattern pile structure, drying after washing is fast, and wiping and cleaning in a wet state can be performed with a light force, so that efficient work can be performed.
