Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a mop with excellent stain resistance, and more specifically, it relates to a mop with excellent stain resistance during cleaning use and re-stain resistance during cleaning. Regarding cleaning motsupu.

PRIOR ART AND TECHNICAL PROBLEMS OF THE INVENTION Most motsupu used for cleaning floors have a base fabric with a row of motu cords sewn on one side and another base fabric sewn on the other side. The structure has such a structure that an engaging portion, that is, a decket, which engages with the mog holder is formed between both base fabrics. Thick canvases are generally used as these base fabrics, but these canvases inevitably get dirty during cleaning, and the stains are not sufficiently removed during cleaning, making it difficult to complete the cleaning and washing regeneration cycle. If the process is repeated over and over again, it becomes unsightly and unusable.

The reason why these canvas fabrics are easily contaminated is that lumps and dirt get into the textures or spaces of the canvas fabric, and that dirt that comes off from the motsupu cord threads during washing re-adheres to the canvas, or that the canvas fabric becomes dirty. It is presumed that the cause is that the dirt acts as a filter against the canvas, causing dirt to sink into the canvas. Furthermore, it is recognized that the shrinkage of the canvas material as the cleaning and washing regeneration process progresses is one of the factors that makes it difficult to remove stains.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to provide a cleaning mop having a base cloth made of canvas, which eliminates the above-mentioned disadvantages.

Another object of the present invention is to provide a moff for cleaning canvas surfaces that has excellent stain resistance during cleaning and re-stain resistance during cleaning, and also has a suppressed tendency to shrink during cleaning.

Structure of the Invention According to the present invention, in a cleaning mop in which a row of mop cords are sewn on one side of the base fabric and another base fabric is sewn on the other side to provide a retaining portion for the mop holder, the base fabric is sewn. A mop having excellent stain resistance is provided, characterized in that the mop is made of a coating material in which a coating layer of an oil-resistant and wash-resistant elastomer is provided on at least the outer surface of a canvas material.

Features and Effects of the Invention As already mentioned, canvas is a durable fabric with a relatively tight weave, but this tight weave is rather effective at removing dirt and grime that accumulates during cleaning. This is thought to be the cause of increased recontamination during cleaning.

The present invention provides a coating layer of elastomer with excellent oil resistance and wash resistance on the canvas fabric that serves as the base fabric of the motu, thereby reducing the tendency of dirt to adhere during cleaning and the ability to remove dirt during cleaning. This is based on the knowledge that not only is there a significant improvement, but there is also a significant improvement in preventing recontamination during mop cleaning.

For example, as shown in the example below, the cleaning efficiency of artificially contaminated cloth made of untreated canvas is extremely low at about 201, whereas nitrile-butadiene rubber (NBR) is used as an oil-resistant and wash-resistant elastomer. ) The cleaning efficiency of the coated canvas provided with the coating layer reaches a high value of about 70 to 80 inches, and the recontamination rate is
In the case of untreated key/lotus, it is on the order of 701, but when the coating amount of NBR mentioned above is gradually increased from zero, as shown in Figure 1 of the attached drawing, as the coating amount increases, The recontamination rate decreases rapidly and saturates to a low value of about 201.

This phenomenon is unique to oil-resistant and wash-resistant elastomers.For example, in the case of canvas coated with ordinary soft vinyl resin (paste resin), the recontamination rate is as high as 64%. Due to its high standard, 1
It is clear that this is something unexpected.

PREFERRED EMBODIMENTS OF THE INVENTION The present invention will be described in detail below with respect to its preferred embodiments.

In FIGS. 1 and 2 showing an example of the mop of the present invention, the mop l has a double-walled base fabric 2, a base fabric (this fabric) 3, and one base fabric, that is, the lower base fabric. It consists of a large number of rows of mop cords 5 sewn onto cloth 2 through seams 4. An opening 6 is provided in the other base fabric, that is, the upper base fabric (this fabric) 3, and a pocket 7 is formed between the upper base fabric 3 and the lower base fabric 2. Pass the mop holder (support) 9' attached to the handle 8 through the opening 6, and then attach the base fabric 2.
By inserting the mop l into the pocket 7 between the base fabric 3 and the base fabric 3, the mop l can be detachably attached to the holder 9.

In FIG. 3 showing the cross-sectional structure of the base fabric 2 (3), the base fabric 2 (3) used in the present invention includes a canvas fabric 10 and an oil-resistant and wash-resistant elastomer coating layer applied to both sides of the canvas fabric 10. It consists of 11.11.

Canvas salts include cotton fiber, polyvinyl alcohol fiber, polyester fiber, nylon fiber, acrylic fiber, etc. Although it is possible to use any canvas made of spun yarn made of polyvinyl chloride fiber alone or a combination thereof, a canvas made of polyvinyl alcohol fiber (vinylon fiber) is preferable from the viewpoint of stain resistance. It is.

As the oil-resistant and wash-resistant elastomer, any known elastomer can be used as long as it satisfies this condition, but as already mentioned, nitrile-butadiene rubber or nitrile-butadiene rubber and acrylic rubber It is particularly desirable to use a composition of. That is, these rubbers have excellent oil resistance and wash resistance, and not only exhibit particularly excellent stain resistance, but also excellent adhesion to canvas salt and abrasion resistance. In addition, as oil-resistant and wash-resistant elastomers, acrylic rubber and urethane rubber 9
Chlorosulfonated polyethylene (Hyparoa)%
7. Raw rubber (fct 7-pyrene-vinylidene fluoride copolymer), oil-resistant polyvinyl chloride (PVC), etc. can also be used.

The amount of coating layer applied to the canvas salt is determined to fill the canvas salt to a minimum, while the upper limit is determined by the texture of the canvas salt and economic considerations. This amount varies depending on the degree of weave of the canvas salt, but generally speaking, it is 50 to 70,091 m.
Especially 150 to 4001! It is sufficient if it is within the range of /m.

From the viewpoint of appearance, it is sufficient to provide a coating layer on the outer surface of the canvas salt, but in order to prevent shrinkage during long-term use, it is better to provide a coating layer on both sides of the canvas salt.

Although the mop of the present invention can be used as a so-called water mop that is used by moistening it with water, it is particularly suitable as a so-called dry mop that is used for cleaning without using water. in this case,
The motsupu cord sewn to the base fabric is oil-impregnated with a mineral oil-based, synthetic oil-based, or vegetable oil-based lubricating oil. It has the advantage of being able to withstand repetition.

Oil impregnation treatment was performed by the method described in Example 1 of Publication No. 7471.

These mowers were cleaned for 11 months and washed in a washing machine (600FLA, manufactured by Tanemoto Seisakusho) together with 490 dirty oil-impregnated motsus. This cleaning process includes three steps using detergent at 40-60C, six rinsing steps at room temperature, and a final step in which the mop is impregnated with oil. This operation was repeated 20 times (using a dirty mop each time), and it was visually observed how the canvas portion of the sample mop was recontaminated. In addition, the shrinkage rate of the canvas portion was also examined.

A prototype mop was made using a canvas coated on both sides, and the re-staining property of the canvas was examined under the same conditions as in Example 3. The recontamination evaluation method was calculated as follows from the Y values before and after the canvas was contaminated.

The results are shown in Figure 4. The results show that as the coating amount increases, the restainability improves and becomes saturated at a certain value.
