Description

Adhesive cleaning nonwoven fabric and its manufacturing method

The present invention relates to an adhesive cleaning nonwoven fabric and a method of manufacturing the same.

Non-woven fabric (Non-woven Fabric) forms a sheet-like web (entangled with various fibers, such as natural fibers, chemical fibers, glass fibers, metal fibers, etc.) according to each other, and combine them by mechanical or physical methods It is a fiber structure with a flat structure.

Recently, various cleaning products and cleaning equipment have been developed and widely used, and one of them is a cleaning cloth. In general, a tack cleaner which is a cleaning cloth is composed of a rod-shaped bag and a cleaning nonwoven fabric mounting portion provided at the end of the bag. Then, the cleaning nonwoven fabric for cleaning the nonwoven fabric in the form of a wide cloth is fixed to use. The cleaning non-woven fabric is made of a rectangular flat plate shape and the material is mainly composed of a polymer (Polypropylene), such as PP (Polypropylene), PET (Polyester) to utilize the static electricity.

The cleaning nonwoven fabric absorbs foreign substances such as dust or hair by utilizing static electricity of the polymer itself. Such a conventional cleaning nonwoven fabric is to adsorb only by static electricity of the material itself, and the adsorption power of heavy dust and debris is weak, making it difficult to clean the cleaning. In addition, the conventional cleaning non-woven fabric is applied to the spunlace nonwoven fabric, which is mostly made by weaving technology using water, such spunlace nonwoven fabric has a high smoothness, the foreign matter only in front of the nonwoven fabric when pushed by a pusher cleaner. Therefore, when the foreign matter on the nonwoven fabric is saturated when cleaning, it causes a problem that it is difficult to remove any further foreign matter. In addition, the conventional spunlace nonwoven fabric is uneconomical because it is impossible to use both sides, there is a disadvantage that the adsorption force, static electricity generation, slip performance is somewhat poor, as well as weak visual stability.

As described above, in order to increase the adsorption force of the cleaning nonwoven fabric, recently, a cleaning cloth is applied mainly to one surface of the base material and performs cleaning using the adsorption force of the adhesive. However, such a cleaning cloth is applied to one side of the base material in the manufacturing process, while the adhesive is absorbed and permeated on the back side of the base material, the unwinding in the processing step after the rewinding of the base material to the adhesive Due to the tearing phenomenon caused by the attachment of the base material there is a problem that causes damage to the product. In addition, the surface to which the adhesive is applied can not be easily distinguished by the user there is a problem inconvenient to use.

Therefore, there is an urgent need for the development of a cleaning nonwoven fabric capable of effectively removing foreign substances while solving the problems of the conventional cleaning nonwoven fabric.

As a technique for increasing the adsorption power by using an adhesive to increase the adsorption power of the cleaning nonwoven fabric as described above, after applying the pretreatment layer on one surface of the base material in the Republic of Korea Patent Publication No. 1106917 "adhesive cleaning cloth and its manufacturing method" As the printing layer and the adhesive layer are sequentially formed on the pretreatment layer, the adhesive layer is prevented from being absorbed and permeated to both sides of the base material so that no tearing of the back surface of the base material by the adhesive layer occurs in the manufacturing process and the adhesive layer by the printing layer is applied. Disclosed is a pressure-sensitive adhesive cleaning cloth and a method for producing the same, which provide an effect that a user can easily grasp the surface of the base metal. In addition, Japanese Laid-Open Patent Publication No. 2008-206948 "Cleaning Nonwoven Fabric" includes a nonwoven fabric, sodium hydrogencarbonate, and abrasive grains, and sodium hydrogencarbonate has an average particle diameter of 10 µm to 80 µm, and abrasive grains have an average particle diameter of 3.

In the present invention, "Fineness" means the degree of fiber or yarn thickness. The thickness of the fibers can be expressed in all denier, but the unit of denier is `` weight per length (1 denier is 9,000m in length and 1g in weight) or one of the units indicating the thickness of green thread. It is prescribed by 1 denier to be g. Denier values are expressed in g per 9,000 m of length and are usually determined by d or medium weights, so that the diameters are different even for denier fibers. Micron (μ) is used to accurately represent the diameter of the fiber, and in general, fineness is often expressed in denier.

In the present invention, 'staple fiber' refers to short fibers having a short length compared to the thickness. Natural fibers, such as cotton, wool, and hemp, are called staple fibers. Most of the staple fibers are included in the staple fibers except for silk fibers.

In the present invention, the term "spunlace" refers to a non-woven fabric that forms a web by combining pulp and fiber by the pressure of water as a fabric made by a weaving technique using water.

In the present invention, the term "web" refers to a semi-finished product in the form of a cotton ball before bonding between fibers.

EMBODIMENT OF THE INVENTION Hereinafter, the adhesive cleaning nonwoven fabric of this invention and its manufacturing method are demonstrated in detail.

In one embodiment of the present invention, the dry weight is 30 to 300 g / m ² , the fiber length is 15 to 51 mm, needle punching the staple fibers of different fineness (Needle punching) Forming; Impregnating or spraying a water-soluble adhesive on the web; And after squeeze (Squeeze) the adhesive-treated web (Web), comprising the step of drying, wherein the water-soluble adhesive comprises at least one adhesive resin and a solvent selected from the group consisting of acrylic resin and polyurethane; , The water-soluble adhesive may be to provide a method for producing a pressure-sensitive adhesive cleaning nonwoven fabric, characterized in that the adhesive resin contained in the solvent 6 to 30% OWF.

First, staple fibers used to manufacture a nonwoven fabric for adhesive cleaning as described above can be used without limitation, polyester (PET), polypropylene (PP), nylon (Nylon) and rayon It is more preferable to use at least one selected from the group consisting of Raylon in terms of stability and economical form.

In this case, the staple fiber may be manufactured so as to have staple fibers having different dryness of 30 to 300 g / m ² and different fineness having a fiber length of 15 to 51 mm.

As described above, the staple fiber should have a dry weight of 30 to 300 g / m ² to ensure sticky and bulky properties of the nonwoven fabric and thus be used as a cleaning nonwoven fabric. If the dry weight of the staple fiber is less than 30 g / m ² , when the water-soluble adhesive is impregnated or sprayed onto the staple fiber, the water-soluble adhesive is less treated, and thus the squeeze performance decreases. Squeeze treatment is not preferred because it cannot be used as a cleaning nonwoven fabric because it has little bulkiness. In addition, when the dry weight of the staple fibers exceeds 300 g / m ² , the water-soluble adhesive is not evenly treated throughout the web when the staple fiber is impregnated or sprayed with the water-soluble adhesive. Friction increases on the surface, making it unsuitable for use as a cleaning nonwoven.

In addition, it is preferable that the staple fiber has a fiber length of 15 to 51 mm from the viewpoint of stability of form and economics. If the fiber length of the staple fiber is less than 15 mm, the fiber length is short, so it may be difficult to maintain the shape when the web is formed. If the length exceeds 51 mm, the stability of the shape of the web may be Excellent but not preferred because of poor bulkiness.

In addition, since the staple fibers are manufactured to have staple fibers with different finenesses using 3 to 50 Denier, the adhesion rate of the dust is significantly increased, and thus it is excellent to use as a nonwoven fabric for cleaning. desirable. When the staple fibers having different fineness as described above have a staple fiber, it is preferable because the formation of a web is complicated and the safety and bulkiness necessary for the nonwoven fabric for cleaning are obtained.

For example, each of staple fibers having different fineness may include a first fiber having 3 to 15 Denier of fineness, a second fiber having 16 to 30 Denier of fineness, and a third fiber having 31 to 50 Denier of fineness It may be made of.

If the staple fiber is less than 3 Denier, the touch is soft but difficult to maintain the shape, if it exceeds 50 Denier the surface feels rough and is not preferable because the cleaning power is poor.

As described above, needle punching of staple fibers having a dry weight of 30 to 300 g / m ² and a fiber length of 15 to 51 mm with different fineness may form a web. .

As described above, the method of forming the web from the fibers generally includes needle punching, spunlace, thermal bond, chemical bond, meltblown, and the like. However, in the present invention, the web may be formed by a needle punching process. As described above, when the web is formed by a needle punching process, the shape of the product and the productivity of the product are improved.

The needle punching process may be to integrally form staple fibers by physically bonding staple fibers using a needle punching machine.

As described above, the adhesive may be evenly applied to the surface of the nonwoven fabric by impregnating or spraying a water-soluble adhesive on a web formed by needle punching staple fibers having different fineness as described above. .

The water-soluble adhesive may include one or more adhesive resins and solvents selected from the group consisting of acrylic resins and polyurethanes. It is preferable to use the above-mentioned materials for the pressure-sensitive adhesive resin in view of adhesive strength and economy. In addition, the solvent is used to control the concentration of the adhesive resin, it can be used diluted to the adhesive resin, the solvent may be water, alcohol, etc., it is most preferred to use water.

In this case, the water-soluble adhesive may be a solvent containing 6 to 30% OWF of the adhesive resin. If the adhesive resin is impregnated or sprayed on a water-soluble adhesive containing less than 6% OWF, the dust adhesion rate is excellent, but it is not preferable because there is a problem that the cleaning efficiency may be lowered due to low friction with the floor. . In addition, when impregnated or sprayed with a water-soluble adhesive containing a concentration of more than 30% OWF adhesive, the dust adhesion rate is excellent, so the cleaning performance is excellent, but the frictional force is relatively too high, so the cleaning nonwoven fabric and the bottom surface are excessive. It is too difficult to use as a cleaning cloth because it is closely adhered to. In addition, the high content of the pressure-sensitive adhesive is not only a problem caused by the tearing damage caused by the adhesive when rewinding, unwinding with the adhesive component, it is not preferable because the pressure-sensitive adhesive component may remain on the skin during cleaning.

When impregnating or spraying the water-soluble adhesive on the web (Web) it is preferable to perform at a rate of 10 to 20 meters / min because it is the best coating properties. If impregnated or sprayed at a speed of less than 10 meters / min, the amount of adhesive resin on the nonwoven fabric increases, so that the water-soluble adhesive is not evenly distributed. If impregnated or sprayed at a speed exceeding 20 meters / min, It is not preferable because the amount of the adhesive resin is not enough to apply evenly because the cleaning power may be reduced.

Next, the adhesive-treated web (Web) as described above may be to squeeze (Squeeze) treatment to obtain a uniform pick-up rate to the nonwoven fabric over the full width of the roller by pressing the squeeze roller.

The squeeze treatment is preferred because 70% to 180% OWF of water soluble adhesive remains in the web to implement proper stickyness. If the water-soluble adhesive is less than 70% OWF in the web after the squeeze process, it is difficult to realize proper cleaning ability due to lack of adhesive resin, and exceeds 180% OWF. There is a relatively large amount of adhesive resin is not preferable because the adhesive may be irritated to the skin during cleaning, and because the friction is high due to excessive adhesive force is not suitable for use for cleaning.

After the squeeze (Squeeze) process as described above, the final adhesive cleaning nonwoven fabric can be prepared through the drying step. By passing through the drying step, the water-soluble adhesive may be seated on the nonwoven fabric so as not to be released during use.

At this time, the drying step may be adjusted to the appropriate drying conditions according to the thickness of the nonwoven fabric, preferably the drying temperature is 110 to 140 ℃, the drying rate is 10 to 20 meters / min, the drying time is 30 to 60 seconds It is preferable to carry out under conditions. If the drying temperature is less than 110 ℃, the drying rate is less than 10 meters / min, and the drying time is less than 30 seconds to dry in a low temperature conditions because the fast drying conditions because the undried portion is generated It is not preferable because the high moisture content of the product can cause non-woven fabrics to stick to each other and cause defects. In addition, when the drying temperature exceeds 140 ℃, the drying rate exceeds 20 meters / min, and the drying time exceeds 60 seconds, it is over-cured (over-drying) to sticky (sticky) of the adhesive resin It is not preferable because the castle is poor and the cleaning power as the cleaning cloth is lost.

When drying under the above conditions, the dry moisture content of the nonwoven fabric is preferably 1 to 5%, which is preferable because of its excellent friction (kgf) and adhesion (%). The lower the dry moisture content, the better the adhesive strength, but if dried at a high temperature for a long time, the water-soluble adhesive component is hard to harden to exhibit the adhesiveness is most preferably in the range of 1 to 5% dry moisture content.

Another embodiment of the present invention is an adhesive cleaning nonwoven fabric prepared by treating a water-soluble adhesive on a web formed of staple fibers having different fineness, wherein the staple fibers have a dry weight. 30 to 300 g / m ² , fibrous length 15 to 51 mm, fineness 3 to 50 Denier, the water-soluble adhesive comprises at least one adhesive resin and a solvent selected from the group consisting of acrylic resins and polyurethanes; , The water-soluble adhesive may be to provide a pressure-sensitive adhesive cleaning nonwoven fabric, characterized in that the adhesive resin contained in the solvent 6 to 30% OWF.

As described above, the adhesive cleaning nonwoven fabric of the present invention is remarkably excellent in dust adhesion rate compared to the conventional cleaning nonwoven fabric, and the frictional force with the bottom is suitable for cleaning, and thus can exhibit excellent performance as a cleaning cloth.

특성 평가: 먼지 부착율(%) 측정Characteristic evaluation: measuring dust adhesion rate (%)

Experimental method for measuring the dust adhesion rate is as follows. First, 2 g of an adherent (Sand, particle diameter: 300-600 μm) was evenly sprayed on a predetermined area (45 cm * 180 cm Vinyl floor). Next, the weights of Examples 1 to 10 and Comparative Examples 1 and 2, which are test specimens (120 * 470 mm), were measured and then attached to the holders. Then, the vinyl floor sprayed with the adhesive was cleaned using a holder to which the test specimen was attached. At this time, at the time of cleaning, the entire vinyl floor was cleaned, and the pressure (force) applied to the cleaner was minimized. After the cleaning was completed, the test specimen was removed from the holder, and the weight was measured to calculate the adhesion rate of the adherend to measure the dust adhesion rate.

Adherent adhesion rate (%) = [(W3-W2) / W1] * 100

W1: 2g of adhesive applied to a certain area

W2: Specimen weight before test (cleaning)

W3: Weight of specimen after test (cleaning)

The results of measuring the dust adhesion rate using the test specimens of Examples 1 to 10 and Comparative Examples 1 to 2 are shown in Tables 3 and 4 below.

TABLE 3

	Example 1	Example 2	Example 3	Example 4	Example 5	Example 6
Dust adhesion rate (%)	64.5	77.4	86.0	87.5	93.5	93.7
