[Industrial applications]

 The present invention relates to a rental mop, and more particularly, to a rental mop that is lightweight, has excellent cleaning properties, dehydration properties, and durability.

[0002]

[Prior art]

 Among the constituent materials of rental mops, cotton, vinylon, acrylic, and nylon are the mainstream materials because of their durability, shape retention, and detergency. Among these, the base cloth sewn with the mop cord and the pocket forming patch cloth sewn around the base cloth to the other surface of the base cloth are the main components of the mop. As materials, cotton, vinylon, acrylic, nylon woven fabrics and knitted fabrics and their surfaces coated with resin or dipping-treated are used. Of these, nylon is an effective material because it has excellent strength, durability, and stain resistance. Therefore, after weaving or knitting with multifilaments, coating the surface with a water-insoluble resin, Or, it is subjected to dipping treatment to prevent misalignment, wrinkles, wire transmission, and fraying of the peripheral part due to slip, and it is used with a shape retention effect.

[0003] For example, Japanese Utility Model Laid-Open No. 1-178859 includes a mop base cloth having an attachment portion to a gripping tool, and a mop cord thread sewn on at least one surface of the base cloth. A cleaning mop, characterized in that the mop base cloth comprises a synthetic fiber mesh net having an antifouling resin or rubber coating and openings having openings of 0.1 to 5 mm. Have been described.

[0004]

[Problems to be solved by the device]

 The use of a woven or knitted fabric made of a nylon material for the cloth portion as a component of the rental mop has great advantages in terms of durability and stain resistance. However, since the nylon yarn surface is generally very smooth and nylon has a low coefficient of friction, there is no misalignment or slippage in the fabric using nylon filament yarn, which is easily available and relatively inexpensive. It is apt to occur, and moreover, slipping easily causes fraying from the cut edge. Further, in a knitted fabric using the same yarn, misalignment and misalignment are likely to occur, and at the same time, yarn loss called a run (transmission line) peculiar to the knitted fabric occurs. Therefore, this is prevented by coating or dipping a water-insoluble resin.

However, by coating or dipping the resin, water permeability and air permeability are impaired and the cleaning property and drying property are deteriorated, and at the same time, disadvantages such as an increase in weight and an increase in cost occur. Furthermore, repeated washing and drying may cause resin peeling and cracking, which may adversely affect the appearance and peeling at the same time, or contaminants may enter the cracks of the cracked resin and promote contamination. . As a method of solving the above problems without coating or dipping non-water-soluble resin, the spun yarn of nylon spun yarn is used instead of the filament system to increase the friction coefficient and at the same time entangle by washing. It is also possible to maintain the weaving or knitting structure by utilizing the occurrence of However, this method has the problems that the demand for nylon spun yarn itself as a general-purpose fiber is low, resulting in high cost and that pills are easily generated on the cloth surface.

Therefore, the present invention provides a rental mop that is a low-cost nylon multifilament cloth used as a component part of a rental mop without coating or dipping a water-insoluble resin. To provide.

[0007]

[Means for Solving the Problems]

 According to the present invention, a mop comprising a base cloth and a mop cord sewn to one surface of the base cloth, and a pocket forming patch cloth sewn to the other surface of the base cloth around the base cloth. In the above, the patch cloth or both the patch cloth and the base cloth are made of nylon multifilament yarn with porous Russell knitting or tricot knitting that has been dipped with a resin that can be washed off even after drying. Wash off the resin and create a mop with exposed nylon filaments. In this case, it is preferable that the cut end of the patch cloth or the cloth piece used as both the patch cloth and the base cloth is protected by a bias tape when the mop is sewn.

[0008]

[Action]

 In the present invention, a porous Russell or tricot knitted fabric of nylon multifilament yarn is used as the backing cloth or both the backing cloth and the base cloth. Nylon multifilament yarn is less prone to redeposition than other synthetic fibers even after repeated rental cycles, that is, cycles of use, washing and regeneration, and it is a staple fiber spun yarn. On the other hand, it has the advantage that the fiber is less likely to be worn or thinned even under severe conditions of use and regeneration, and the production thereof has the advantages of a small number of steps and a low price. One of the characteristics is that the nylon multifilament yarn is made into a multi-pore Russell or tricot knitted fabric. In Russell knitting and tricot knitting, by knitting with an appropriate gauge and number of courses, and by selecting a knitting design, it is possible to create a structure that is less likely to cause misalignment and wobbling. Sufficient effect can be achieved by using a plurality of reeds in two or more reeds in the (horizontal) direction. Since it is a knitted material, fraying due to slip around the cut cannot occur.

By doing so, a relatively inexpensive nylon multi-filament yarn is used, and an extremely high density areal weight is not performed, and sufficient shape retention is maintained in a porous state with a relatively large gap. It can be used as a piece of cloth for the rental mop parts you have. Therefore, such a mop has better washability, dehydration, and dryness than a mop that uses a cloth piece coated with a water-insoluble resin or subjected to dipping treatment as its base cloth or patch cloth, and is light in weight. It becomes possible to finish things.

By the way, if a porous Russell or tricot knitted fabric of nylon multifilament yarn is directly sewn on a mop as a backing cloth or a base cloth, there is no distortion and a satisfactory shape and stable quality are obtained. It is difficult to manufacture a mop with good characteristics. In order to improve this, a resin that can be washed off even after drying is applied to a porous Russell knitted or tricot knitted fabric, and the resin is used for sewing to a mop. Since the dipped resin has been washed off at the stage of actual use as a product, it is not necessary to make the dipping resin and the dipping resin aesthetic and durable. Therefore, a relatively low cost dipping process is sufficient, and at the same time, once the resin is washed off, it is not necessary to perform continuous coating or control of the dipping state.

In the present invention, by using the porous Russell knitting or tricot knitting fabric of nylon multifilament yarn as the patch cloth or both the patch cloth and the base cloth, the cloth material has a high density structure. Compared with the case, the warp and distortion of the fabric when the rental cycle is repeated can be reduced, and the dirt can be discharged to the outside, that is, in the washing bath through the openings of the mesh when washing, It is possible to prevent dirt from accumulating during the pocket of the.

It consists of a sewn pocket forming pad 3. In the present invention, the patch cloth 3 or both the patch cloth 3 and the base cloth 1 are formed by porous Russell knitting or tricot knitting of nylon multifilament yarn.

More specifically, the base fabric 1 has a rectangular shape with rounded corners, while the backing fabric 3 has the same shape and dimensions as the base fabric 1, but It consists of a long side part 3a with a large size and a short side part 3b with a relatively small size. There is a cutout part between the two parts, and the base cloth 1 is exposed at this part. ing.

Bias tape 4 for protection is applied to the peripheral portions of the base cloth 1 and the backing cloth 3 so as to wrap the edges, and one surface of the tape 4, the backing cloth 3, the backing cloth 1, and the tape 4 are provided. The other surface and the mop cord 2 are sewn together with a sewing thread 5. The mop cord 2 is provided so as to protrude outward by a predetermined dimension (mop cord length) from the periphery of the base cloth. Protective bias tapes 6a and 6b are also sewn on the edges of the openings of the long side portion 3a and the short side portion 3b of the patch cloth with sewing threads 7a and 7b, respectively.

When assembling the mop to the gripping tool (not shown), one end of the gripping piece of the mop gripping tool is inserted into the pocket between the long side portion 3a of the patch cloth and the base cloth 1, and then the mop is held. The other end of the gripping piece of the gripping tool is inserted into the pocket between the short side portion 3b of the backing cloth and the base cloth 1. The mop is fixed to the gripping tool by the action of a spring of the gripping piece, by fastening the mop and the gripping tool with a string, or by engaging with a surface adhesive fastener provided on the mop and the gripping piece. Can be performed by a mechanism known per se.

Porous Russell knitting or tricot knitted fabric, which constitutes the backing cloth or both the backing cloth and the backing cloth, is a structure in which a plurality of warp knitting is connected to chain knitting in the warp direction and weft knitting in the weft direction. Has become. This knitting structure is formed by using one or a plurality of reeds (back) for weft direction knitting and a reed for chain knitting in the warp direction.

FIG. 2 shows a weave design of a preferred example of the porous Russell knitted fabric used in the present invention. In the porous Russell knitted fabric 10 of this figure, a chain knitting (front) 11 in the warp direction and a weftwise knitting (back) 12 that connects three warp knits 11 form a lacel knitted fabric. I know that

In order to use the porous Russell knitting or tricot knitting fabric 10 as a part of a rental mop, it is necessary to have a waist as a material, shape retention and durability, and a total thread specification is 50 to 50. Nylon multifilament yarn with 1000 denier and filament count 2 to 500 is used and knitted with gauges 16 to 50 and courses 8 to 50. In addition, it is preferable that the number of reeds is plural in order to prevent a run. The nylon multifilament is preferably composed of nylon 6, nylon 66, etc. The multifilament yarn may be so-called undiluted dyed yarn or a normal dyed yarn.

As the water-soluble resin used for depping, starch paste and polyvinyl alcohol can be said to be the most common, but in addition to this, various types such as acrylic type and polyamide type are also industrially used by chemical manufacturers. It is on sale from. No special selection is required for this, as it will be washed off after sewing. These resins are impregnated by deepening to obtain optimum material hardness for sewing.

As the mop cord yarn to be sewn to the base cloth, a spun yarn or a multi-filament yarn made of one or more of cotton fiber, rayon fiber, polyvinyl alcohol fiber, acrylic fiber, nylon fiber and other synthetic fibers is used. Can be used. Generally, the length of the mop cord is preferably in the range of 30 to 200 mm, and the mop cord yarn may be twisted by heat-sealing yarn or twisted to prevent fraying by forming a loop at the tip. The cord yarn may be crimped or uncrimped, and the cord length may be constant or different from each other. The fineness of the cord yarn can also be varied significantly and can range from 500 to 10,000 denier total.

The cord yarn of the dust control mop has a function of adsorbing and retaining dust adhering to the cord yarn on the cord yarn by rubbing against a wiping surface such as a floor. In order to further enhance the dust adsorption / holding action of the mop cord yarn, the dust adsorption liquid can be applied or impregnated on the mop cord yarn. Such dust-adsorbing liquids include, for example, liquid paraffin, spindle oils, alkylbenzene oils, diester oils, mineral oils such as castor oils, synthetic oils or vegetable oil-based oil agents, and Japanese Patent Publication Nos. 53-10194 and 53- An aqueous dust adsorbent described in 37471 can be mentioned.

The present invention will be specifically described in the following examples, but the present invention is not limited to these examples in any sense. (Example 1) Using a nylon multifilament yarn having a total 210 denier and a filament count of 15, a 16-gauge, 16-course, 2-reed Russell knitting fabric was knitted by the knitting method shown in FIG.

The dough was depped with 20% of polyvinyl alcohol, and the paste was hardened. The mop of FIG. 1 was sewn using this cloth. The mop had a base cloth length of 240 mm, a base cloth width of 60 mm, and a mop cord length of 70 mm. In terms of sewing, the use of this fabric did not cause any problems, and the sewability was good.

Example 2 The mop sewn in Example 1 was washed in the same manner as the dust control mop washing method to wash off the sizing material, and then oil processing for the dust control mop was performed. This mop was dried in a stable electric laundry dryer in a heated state. The reduction curves of the mop weight with drying were compared, and it was found that the same drying efficiency was obtained using cotton canvas instead of the knitted fabric of Example 1. An increase of about 15% was seen for the mop sewn by the sewing machine.

Example 3 The dust control mop processed in Example 2 was washed and dried 20 times together with other dust control mops actually used for cleaning, but was contaminated. There was no. In addition, the morphology was stable, and there was no swaying, misalignment, or fraying.

[Effect of device]

 In the present invention, by using porous Russell knitting or tricot knitted fabric of nylon multi-filament yarn as the backing cloth or both the backing cloth and the backing cloth, misalignment and dripping are less likely to occur, The organization can be effectively prevented (line). In addition, since it is a knitted fabric, there is an advantage that fraying due to slip around the cutting edge cannot occur.

By doing so, a relatively inexpensive nylon multi-filament yarn is used, and an extremely high density areal weight is not performed, and sufficient shape retention is maintained in a porous state with a relatively large gap. It can be used as a piece of cloth for the rental mop parts you have. Therefore, such a mop has good cleaning properties, dewatering properties, and dryness compared to a mop that uses a piece of cloth coated or dipped with a water-insoluble resin as its base cloth or patch cloth, and is lighter. It becomes possible to finish it.

In addition, the nylon multifilament yarn has a smaller tendency of recontamination than other synthetic fibers even when the rental cycle, that is, when the cycle of use, washing and regeneration is repeated a large number of times, and the staple fiber. Compared with spun yarns, it has the advantage of less fiber wear and fineness even under severe use and recycling conditions, and also has the advantage of a small number of steps and low cost in its production. To be

[0029] Further, a mop having a satisfactory shape free from distortion and having quality stability is manufactured by subjecting a porous Russell knitting or tricot knitting fabric to a water-soluble resin by dipping and subjecting it to sewing to a mop. Since the dipping resin is washed off at the stage where it is possible and is actually used as a product, it is not necessary to make the dipping resin and the depping resin have good appearance and durability. Therefore, dipping can be performed at a relatively low cost, and at the same time, once the resin has been washed off, there is no need to perform continuous coating or control of the dipping state.

Furthermore, by using porous Russell knitting or tricot knitting, warp and distortion of the fabric when the rental cycle is repeated are increased as compared with the case where the fabric has a high density structure. It can be made small, and the dirt can be discharged to the outside, that is, in the washing bath through the mesh openings of the cloth during washing, and the dirt can be prevented from being accumulated in the pocket of the mop.
