Description

Functional Non-Woven Villi Towel with Enhanced Washing Power {PROTRUDED HYDROUS NON-WOVEN SHEET TOWEL FOR IMPROVING OF CLEANSING AND CLEANING CAPABILITY}

The present invention relates to a water-repellent non-woven viscoelastic towel made of a loop type non-woven fabric, and reinforced with a non-woven fabric. In the present invention, a product in which the loop type chorionic wrinkle nonwoven fabric is used includes a wet towel, a wet tissue and a wet towel.

In addition, products made of loop type chortle nonwoven fabrics include handkerchiefs, toilet paper erasers, face wash towels, dishwashing scrubbers, and electrostatic cleaning cloths.

 Detailed Description of the Invention The present invention manufactures a loop type choruffle nonwoven fabric, that is, a nonwoven chorillary towel fabric, in which a wrinkled loop is stacked on the surface of a nonwoven fabric to serve as an odd villi in a textile towel, and a nonwoven chorillary nonwoven fabric is produced. It is to manufacture disposable non-woven villi towels with improved cleaning and water content. In addition, the present invention is that the hole formed on the back surface of the nonwoven fabric while extracting the loop type villi wrinkles on the surface of the nonwoven fabric is an important feature to show the improved function of the nonwoven villi towel of the present invention.

This invention makes it possible to replace the function and role of the towel having the irregular villi of the fiber towel from the nonwoven fabric to the loop type chorionic nonwoven fabric.

Disposable wipes or disposable wipes are widely used in urban life. Disposable wipes are discarded after one use without repeated use of the cleaning cloth, thus preventing the wipes from becoming germ propagation paths. Disposable wipes are provided for customers to clean their hands at restaurants, used to wipe the stool during the baby's care, and to clean the patient's body in the hospital.

1) The improvement of the existing disposable non-woven towel or wet tissue is to apply functional villi such as towel villi on the surface of non-woven tissue. Nonwovens used in the manufacture of disposable wet wipes, non-woven products of wet wipes, spunlace nonwovens, hydrophilized polypropylene (PP) melt blown nonwovens and other hydrophilic PP nonwovens are commonly used. Since these nonwoven fabrics have a flat and smooth surface, adhesion and washing power are inferior to those of fiber towels with irregular villi on the surface. In order to improve this problem, an embossing pattern is applied to the surface of the nonwoven fabric to increase the adhesion of the nonwoven towel. The embossed concave-convex pattern of the nonwoven fabric towel is provided with a concave-convex of about 50 μm deep to the surface of the nonwoven fabric having a thickness of about 400 μm. The unevenness given by the embossing pattern on the surface of the nonwoven fabric improves the adhesion and flexibility of the nonwoven fabric to some extent, but it lacks a lot of adhesion compared to the villi wrinkles of the textile towel.

2) Another problem with nonwoven wipes is the hazard of the chemicals contained in the nonwoven wipes. Korean Patent Publication No. 10-1998-0086503 points out the side effects of skin caused by non-woven towels containing surfactants, fungicides, and preservatives.

Review the background of the use of chemicals in non-woven towels. A preferred low cost nonwoven fabric that can be substituted for the woven wipes is a PP series nonwoven fabric having a weight of 5 to 80 g / m 2. In the wet towel and wet tissue materials, hydrophilized PP melt blown nonwoven fabrics are most commonly used, and non-woven fabrics produced by combining PP spunbond nonwoven fabric, PP spunbond and melt blown in one process, and spunlace nonwoven fabric Are also used. PP-based nonwoven fabrics, however, are made of a hydrophobic fiber layer that does not absorb water at all. When water is spilled on the inclined surface of an unhydrophilized PP nonwoven, the water flows down without wetting the nonwoven surface. In order for the hydrophobic PP nonwoven to absorb water, a hydrophilic agent should be coated on the PP nonwoven. For non-hydrophilic coating, the PP nonwoven is dipped into a hydrophilic solution and then the nonwoven is dried in hot air and a heating roll. Hydrophilic agents are surfactant-based chemicals similar to soaps and shampoos. Using a hydrophilic wipes leaves traces of surfactant in the wipes on your skin. Surfactant remaining on the skin is bad for the human body in the skin, especially the skin of the infant or around the lips with low resistance.

3) Another problem pointed out in disposable wipes is the problem of the use of chemicals in the wipes. Existing wet wipes may be deteriorated during the distribution period, so as a preparation for this, disinfectants, alcohols, fungicides, preservatives, and surfactants to enhance the cleaning power are included in the wet towel solution. The chemical agent of the surfactant or alcohols prevents deterioration during distribution of existing disposable non-woven wipes or wet wipes, and improves washing power.

Other nonwoven fabrics used for cleaning include kitchen towels, electrostatic cleaning cloths and toilet paper. Kitchen towels, electrostatic cleaning cloths, toilet paper and the like are relatively expensive, there is no projection of the fiber, there is also a lack of cleaning power, low-cost and reinforcing power is required.

The present invention aims to provide a new type of functional nonwoven villi towel for strengthening the cleaning power for use of PP series nonwoven fabric as a towel. The present invention is a loop made of a gathered elastic fiber aggregate folds by stacking a bundle of elastic fibers in a loop shape on the surface of the nonwoven fabric to serve as a bumpy villi of the fiber towel. To provide a distributed nonwoven villi towel. The present invention is to arrange the loop-shaped villi wrinkles on the surface of the nonwoven fabric to provide a non-woven villi towel that has no heterogeneity and adheres to the skin. The present invention further includes a low density nonwoven web based on a nonwoven fabric in which a nonwoven fabric with a loop-shaped villi wrinkle is made to lower the fiber density, an unevenness of the nonwoven fabric formed of a hole punched in the nonwoven fabric, and an unevenness added by embossing the nonwoven fabric. It is intended to provide a non-woven vill towel with improved adhesion and cleaning power.

The manufacturing process of polyolefin-based spunbond nonwoven fabric (S) mainly melts polypropylene (PP) raw materials in an extruder, spins the melted resin from nozzles to 1 denier to 5 denier, and spins the spun fibers from a heating roll to a nonwoven web. By stacking and heat pressing to harden into a sheet type, a sheet-like nonwoven fabric having a high fiber density and a thin thickness is produced.

 According to the present invention, even if a hydrophobic polyolefin-based nonwoven fabric without hydrophilic treatment is added to the nonwoven fabric by a loop punching process, the fiber density of the nonwoven fabric becomes low, and a channel is formed between the widened fibers, and the nonwoven fabric perforated hole forms a channel. Therefore, it allows water to penetrate and exhibits properties similar to hydrophilicity. In addition, when the hydrophobic nonwoven fabric is subjected to corona discharge treatment, water absorption is improved. The present invention can be used in the use of wet towels and wipes as a hydrophobic reinforcing villi towel because the hydrophobicity of the nonwoven fabric is weakened through the mechanical nonwoven fabric treatment.

In this invention, hydrophilicity is improved to a low-cost hydrophobic nonwoven fabric as a mechanical treatment without hydrophilic treatment by a chemical agent. As a mechanical treatment to increase the hydrophilicity, the present invention was subjected to corona discharge treatment to increase the hydrophobic nonwoven fabric functionality.

(The process of extracting loop-shaped villi wrinkles on the surface of the nonwoven fabric and the process of forming the perforation hole and the low density nonwoven web)

delete

The present invention produces a loop-shaped villus (23) by extracting villi of 0.1 to 5 mm in length from the surface of the nonwoven fabric so as to act as an irregular villi of the fiber towel. In the present invention, pin punching is performed while heating and pressing the back surface of the nonwoven fabric with the heated punch 11a pin and the pocket 12a in order to extract the loop type villi wrinkles 23 on the surface of the nonwoven fabric.

In Fig. 1 an apparatus for punching nonwovens is cited. In FIGS. 1 and 3, the punching for the extraction of the loop type villi 23 is performed by the pin punch 11a roll 11 and the pocket 12a where the nonwoven fabric 21 supplied from the nonwoven fabric supply roll 20 is heated. ) The nonwoven fabric 24, which is supplied between the rolls 12 and pin-punched on the back surface of the nonwoven fabric in a heated and pressurized state, and has a loop-shaped villi wrinkles 23, is recovered to the roll 22. The fibers of the nonwoven web stacked on the sheet during the punching process are formed by the action of the pin punch 11a, and the nonwoven web elastic fibers are reassembled into the loop-like aggregates into the loop-like aggregates. Subsequently, it is stacked and cured in a loop shape on the surface of the nonwoven fabric, and the extraction is completed in the shape of a loop type villi 23. At the same time, as the fiber movement of the nonwoven web occurs a lot during the extraction process, the nonwoven web is swollen to form a low density nonwoven web based on a nonwoven fabric having a low fiber density. Through this process, the nonwoven fabric is a fabric 24 of a functional nonwoven villi towel having nonwoven villi represented on the nonwoven surface, which is represented by a loop type villi wrinkle 23, like the villi of a woven paper towel.

In Figure 2 cited different punching rolls. Referring to FIGS. 2 and 3 together, the punching for chorionic wrinkles is obtained by the pin punch 11a roll 11 and the pocket 12a roll 12 in which the PP nonwoven fabric supplied from the nonwoven fabric supply roll 20 is heated. The nonwoven fabric 24, which is supplied and punched between the pin punch rolls 11 and the secondary pockets 13a, and the second punched, and then the loop-shaped villi wrinkles 23 is formed, is roll 22 ) Is recovered. The fibers of the nonwoven web stacked on the sheet during the punching process are formed by the action of the pin punch 11a, and the nonwoven web elastic fibers are reassembled into a loop-like assembly (into), and then the back of the punching hole 23a of the nonwoven fabric by the action of heating and pressing. The surface of the nonwoven fabric is stacked and cured in a loop shape to finish the extraction in the shape of the loop type villi 23. At the same time, as the fiber movement of the nonwoven web occurs a lot during the extraction process, the nonwoven web is swollen to form a low density nonwoven web based on a nonwoven fabric having a low fiber density. Through this process, the nonwoven fabric is a fabric 24 of a functional nonwoven villi towel having nonwoven villi represented on the nonwoven surface, which is represented by a loop type villi wrinkle 23, like the villi of a woven paper towel.

In this invention, the punching of the said nonwoven fabric punched the nonwoven fabric using the pin punch roll set. The pin punch 11a roll 11 has arranged a pin punch with the ends of the pins in the shape of a mountain in order to perforate the nonwoven fabric and to form a villi wrinkle, and is heated for thermoforming of the nonwoven fabric. The detail of the pin punch reflects the size and height of the loop protrusion to be drawn onto the nonwoven fabric.

In Fig. 1, when punching by heating and pressing with a pin punch roll on the back surface of the nonwoven fabric, the loop-shaped elastic nonwoven fibers pushed by the pin punch are raised to the nonwoven surface behind the perforated holes 23a and pleated in a loop shape. The stacked nonwoven elastic fibers form a looped villi 23. The villi rise to a height of 0.1 mm to 5 mm above the nonwoven floor.

A base pocket roll 12 or 13 is configured to support the nonwoven fabric and to eject the elastic fibers onto the villi when the nonwoven fabric is heated and pressurized with a pin punch roll. The base pocket roll arranges forming pockets 12a or 13a in one-to-one correspondence with pin punches of pin punch rolls on the roll surface. The detailed shape of the pocket reflects the size and height of the elastic fibers to be drawn onto the nonwoven. The present invention is a sheet-like nonwoven fabric that is heat punched between a heated pin punch roll and a heated pocket roll, and the elastic fibers are extracted and cured into a loop-shaped villi, forming a loop-shaped villi at the desired density and size on the nonwoven surface. .

In this invention, the pin punch roll 11 which arranged about 130,000 pin punches 11a every about 1 square meter was used. The pocket rolls 12 and 13 corresponding to the pin punch rolls also formed about 130,000 molded pockets 12a per square meter. The pin punch rolls 11 and pocket rolls 12, 13 of this invention correspond very precisely and undergo a precise thermal punching process to arrange the nonwoven villi, which is a collection of desired elastic fiber loops on the nonwoven surface.

The present invention punches out a sheet-like nonwoven fabric between a heated punch roll and a heated pocket roll to extract a projection-like looped villi with bulging fibers on the surface of the nonwoven fabric. Is determined by the density of the punch pins installed on the pin punch rolls and the body diameter of the punch pins.

Heating punching to extract loop-shaped villi wrinkles on the surface of the nonwoven fabric simultaneously makes perforation holes in the nonwoven fabric, and these perforation holes increase the functionality and act as the irregularities of the nonwoven fabric, thereby increasing the washing power of the nonwoven fabric by the perforation irregularities.

delete

The loop-shaped villi wrinkles extracted by the pin punch rolls and pocket rolls realize the texture and adhesion of the uneven fabric towel. This loop-shaped villi are composed of fine fibers with a fiber diameter of 0.1 to 10 denier, so unlike the existing disposable wipes or wipes that touch the skin, it is very soft to the skin. There is no damaging irritation. In addition, such nonwoven loop type chorionic wrinkles exhibit excellent adhesion and washing power, thereby reducing the need for surfactants. As described above, the loop-shaped villi wrinkles protruding to the surface of the nonwoven fabric of the present invention are soft and tightly adhered to the skin wrinkles when they come into contact with the skin, thus exhibiting a very good cleaning power and exhibiting a softer touch than the fiber towel villi.

delete

Although the punching tool of the present invention refers to pin punch rolls and pocket rolls, the same nonwoven villus can be produced in a plate process using pin punch plates and pocket plates. In addition, in the above-described plate process, one side (surface) of the nonwoven fabric forms a nonwoven villi wrinkle and has a hole in the nonwoven fabric perforated hole formed by pin punch on the other side (lower surface).

delete

The perforation rate of the nonwoven fabric perforations should be at least 5% of the area of the nonwoven fabric so that the looped villi wrinkles well on the surface of the nonwoven fabric. The perforation rate of the nonwoven perforation hole is proportional to the composition area of the loop-shaped villi and the body area ratio of the punching pin.

delete

delete

It is unreasonable to set the drilling rate of the drilling holes arranged in the nonwoven fabric mechanically to 50% or more of the nonwoven fabric area.

In this invention, the drilling rate of the said drilling hole was calculated by the ratio of the trunk cross-sectional area of the punching pin.

The nonwoven fabric perforated hole is formed in the loop-shaped villi wrinkles irregularities on the surface of the nonwoven fabric to have an improved cleaning power, thereby increasing the functionality and cleaning power than the nonwoven fabric before drilling.

In the present invention, when pin punching the nonwoven fabric, the fiber density of the nonwoven web of the nonwoven web where the nonwoven fabric is not pin punched is reduced. The line speed of the punching line for pin punching the nonwoven fabric is preferably at a low speed of 30 m / min or less. Low speed pin punching is of great importance for the composition of nonwoven based low density nonwoven webs which reduces the fiber density of nonwoven nonwoven webs in the non-pin punched region.

delete

delete

In the process of low speed pin punching, the nonwoven web of the nonwoven fabric is not cut and the fiber is moved well and the punching moment acts as the fibers of the nonwoven web are stressed by the tension and the stress tension of the fibers is released immediately after punching. The nonwoven web of the nonwoven is swollen and the fiber density of the nonwoven web is reduced.

The loop-shaped villi wrinkled nonwoven fabric to which the uneven pattern is added is composed of a portion in which the thickness of the nonwoven web is maintained because the embossed crimping pattern is not applied, and a portion of the pattern portion is pressed or bonded into a plate to form a concave pattern. These two parts form irregularities with a difference in thickness in the nonwoven villi towel, thereby increasing the cleaning power when the nonwoven villi towel is used as a towel or water tissue.

delete

Looking at the uneven structure, the thickness of the weighing 40g / ㎡ PP spunbond nonwoven fabric is about 300㎛. If the nonwoven fabric is formed in the ultrasonic bonding machine in the shape engraved on the embossing roll, the pressing portion has a thickness of about 44 μm. Therefore, the depth of this unevenness is about 200 µm.

For example, when the embossing pattern of the ultrasonic embossing roll has a diamond line shape, secondary irregularities are formed due to the squeezed thickness of the diamond line width and the undeformed nonwoven villi towel thickness variation.

In this way, when the irregularities are added to the loop type nonwoven fabric of the pleated wrinkles, the washing power of the water-containing nonwoven villi towel is improved.

delete

The embossing pattern of the embossing shape can be freely made in an arbitrary shape by using lines, lights, and the like.

In the present invention, the non-woven villi wrinkles are described as loop-shaped villi wrinkles formed by gathering wrinkles by gathering the aggregate (inner) of the nonwoven elastic fibers from the non-woven sheet into a wrinkle loop. Loop-like elastic filamentous gathers of loop-shaped villi wrinkles increase the area where the elastic strands of the fibers touch the skin folds, increase adhesion to the skin, and separate the skin deposits from the skin when moving these nonwoven villi from the skin surface It will increase the cleaning efficiency.

In addition, a nonwoven fabric perforated hole in which the nonwoven fabric is perforated and distributed is formed on the back surface of the nonwoven fabric on the opposite side of the loop-shaped villus fold, and the concave-convex structure by the perforated hole increases the functionality and cleaning power of the nonwoven fabric.

The improvement of the cleaning effect of the nonwoven villi towel of the present invention is achieved not only by the adhesion of the villi wrinkles extracted on the surface of the nonwoven fabric, but also by the construction of the low density nonwoven web based on the nonwoven fabric which reduces the fiber density of the entire nonwoven nonwoven web.

This cleaning power is to enable the use of the water-containing villi of the present invention in the use of disposable scrubber, electrostatic cleaning cloth, toilet paper cleaner, handkerchief and the like.
