Description

[Technical scope]

The present invention relates to a fabric base for a disposable textile product that can be used to produce a disposable textile product, such as a disposable underwear and a diaper. The present invention also relates to a disposable textile product manufactured using a fabric base.

[Prior art]

The fabric base for a disposable textile product is widely used for diapers, hygiene products, as well as underwear, clothes and bedding, which can be used temporarily during trips, emergencies, outdoors, in a hospital, institution and hotel. The fabric base should provide a pleasant feeling when wearing a fabric product on the body. For example, in the case of a diaper, hygiene product or underwear, an essential property that is essential for the fabric base is a pleasant feeling of conformity to body size, a pleasant feeling of contact when in contact with the skin, good breathability and good ability to evaporate moisture, which provide sweat absorption and the ability to drying (hereinafter referred to simply as the ability to evaporate moisture).

In the case of a diaper, which is one disposable tissue product, the material of the non-woven fabric is most often used as the fabric base material, taking into account its functional characteristics. For example, in PTL1, a disposable diaper is described in which the inner liner is fixed to the diaper web, the diaper web being adapted to introduce absorbent material, such as cotton pulp, between a liquid-permeable top layer made of a nonwoven fabric and a liquid-impervious lower layer made made of polyethylene, etc., and the inner liner is likewise adapted to introduce an absorbent, for example cotton cellulose, between a liquid-permeable top layer, anufacture of nonwoven fabric and a liquid-impermeable backsheet made of polyethylene and m. p.

When using disposable sleepwear, which is provided to a hotel resident, etc., it was proposed to give her the function of skin care. For example, PTL2 describes disposable sleepwear that has been treated with an impregnation or coating of a non-woven fabric base with a lipophilic moisturizer, and this treatment involves the addition of a skin care function.

[Summary of the invention]

[Technical Problem]

PTL1 presents a problem that is associated with the fact that, despite the breathability of the nonwoven fabric, which is used as a material for a liquid permeable top layer, its ability to evaporate moisture is low. Moreover, although in the diaper described in PTL1, a liquid-impervious lower layer is used to prevent the secretion of the body, such as urine, from leaking out, such a liquid-impervious lower layer is also inherently low in moisture evaporation. It is essentially known that the lower layer of the diaper was also given moisture permeability, but no attempt was made to improve its ability to evaporate moisture. Thus, the fabric base material for use in a traditional disposable diaper does not have sufficient ability to evaporate moisture, and water vapor generated by sweat or the like remains inside the diaper, thus inevitably causing unpleasant sensations of sweating and stickiness.

Another drawback of the fabric base material used in a traditional disposable diaper is its low ability to transfer heat, i.e. the ability to dissipate the heat released by the body into the environment, and the heat that accumulates in the diaper causes discomfort. In addition, when a diaper is worn, contact with the fiber material creates an unpleasant sensation on the skin that is characteristic of the fiber material, without a pleasant sensation of cool contact and smoothness, which, for example, is inherent in the cotton material, and there is no feeling of freshness when worn . Thus, there is the possibility of improving the fabric base, which is part of a disposable textile product.

The disadvantage of the disposable sleepwear described in PTL2 is that the fabric base itself does not provide a skin care function, and the intended skin care function is imparted by subsequent processing, for example, impregnation or coating with a lipophilic moisturizer, resulting in a process The fabrication becomes complicated and expensive.

For a fabric base material for a disposable textile product that is in direct contact with human skin, it is generally required that the fabric base itself be flexible and provide a general feeling of softness and density. Moreover, from the point of view of appearance and attractiveness, the fabric basis of clothes for travel, emergencies and outdoor use should effectively and efficiently demonstrate a high level of diverse aesthetic design, and should also provide information opportunities, such as messaging, marketing information and advertising. In addition, it is also desirable that it can be given various functions depending on the application.

The present invention is the provision of a fabric base for a disposable textile product, which has excellent ability to evaporate moisture, the ability to heat transfer and moisture permeability. Another objective of the present invention is the provision of a disposable textile product that creates an excellent feeling when worn with a pleasant contact with the skin, has the ability to evaporate moisture, the ability to heat transfer and moisture permeability through the use of a fabric base in accordance with the present invention as a fabric base for a disposable textile products.

Another objective of the present invention is the provision of a fabric basis for a disposable textile product, which can effectively and efficiently demonstrate a variety of design and text information, and also creates a general feeling of softness and density, is flexible and comfortable to wear, using the texture that is characteristic of the material itself tissue basis. Another objective of the present invention is the provision of a fabric base for a disposable textile product, which allows you to effectively and efficiently give it a variety of functions in accordance with the application and simplifies its production, as well as the proposal of a disposable textile product that implements the properties of the fabric base.

[Description of Embodiment]

An embodiment of the present invention will be described later herein with reference to the accompanying figure. In FIG. 1 is an embodiment showing the surface condition of a fabric base 1 of an embodiment of the present invention. The fabric backing 1 in FIG. 1 is continuous in the x direction, which is the first direction. Reference designation 5 refers to an elastic element that is located inside the fabric base. The figure shows a configuration in which a large number of elements of an uneven surface are formed by a large number of elastic elements 5. As shown in FIG. 2, a large area of the corrugated part 6 is formed by a large uneven surface.

As shown in FIG. 4 and 5, the fabric base 1 is made of a laminated sheet 30, which contains a first fiber sheet 2 having air permeability, and a second fiber sheet 3, also having air permeability, and a material 4 consisting of fibers is located between the first fiber sheet 2 and the second fiber sheet 3 having the ability to distribute liquid, while the laminated sheet is obtained by laminating the first fibrous sheet 2, the second fibrous sheet 3 and consisting of fibers of material 4. The first fiber the first sheet 2 and second sheet 3, a fibrous layer comprise fibers having an air permeability and consisting of fiber material 4 comprises a layer of fibers has the ability to fluid distribution. Thus, the laminated sheet 30 forms a composite layer 31 in which a fiber layer having breathability (breathable fiber layer) and a fiber layer having liquid distribution ability (liquid distributing fiber layer) are laminated. The composite layer 31 has a three-layer structure including a first breathable fiber layer, a liquid distribution fiber layer adjacent to the first breathable fiber layer, and a second breathable fiber layer adjacent to the liquid distribution fiber layer.

The first fiber sheet 2 and the fiber material 4 are bonded to each other at regular intervals by an elastic member 5. The second fiber sheet 3 and the fiber material 4 are preferably bonded to each other at regular intervals. Adhesive bonding, thermal splicing and ultrasonic welding may be used as bonding agents, but from the point of view of ease of manufacture, adhesive bonding is preferred. An embodiment of the present invention will be described later herein with reference to a case in which adhesive bonding is used as a bonding agent.

In the case of adhesive bonding as a bonding agent, a hot-melt adhesive is used as an adhesive. An embodiment of the present invention will be described later herein with reference to an example in which a hot-melt adhesive is used as an adhesive. In order to bond the second fibrous sheet 3 and the fiber material 4 at regular intervals using hot-melt adhesive, as shown in FIG. 14, the hot-melt adhesive is applied at intervals to the material 4 made of fibers (alternatively, hot-melt adhesive can be applied to the second fiber sheet 3 at certain intervals), and the second fiber sheet and the fiber material are laminated and bonded. In this case, a non-adhesive portion 8, in which there is no adhesive layer 7, is formed between the second fibrous sheet 3 and the material 4 consisting of fibers, and due to such a non-adhesive portion 8, a space 9 is formed. Since the elastic element 5 is located between the first fibrous sheet 2 and consisting of fibers of material 4, bonding the first fibrous sheet 2 and consisting of fibers of material 4 at certain intervals by bonding the first fibrous sheet 2 and consisting of fibers of mate rial 4 in the region of the elastic member 5. Thus, as shown in FIG. 14, a hot-melt adhesive is applied by spraying on the external perimeter a large number of elastic elements 5 parallel to each other with a predetermined gap, while the elastic element 5, on which the hot-melt adhesive is applied, is placed between the first fibrous sheet 2 and the surface of the material 4 consisting of fibers in the laminated sheet of the second fibrous sheet 3 and consisting of fibers of material 4, and lamination is carried out so that the elastic element 5 is located between the surface material consisting of fibers 4 in the laminated sheet and the first fibrous sheet 2, and the layers are joined by bonding. The opposite surface of the first fibrous sheet 2 and the material 4 consisting of fibers, in which there is no elastic element 5, becomes a non-adhesive section 8, and the space 9 is formed by a non-adhesive section 8 (this feature, in particular, not shown in Fig. 14). In FIG. 15 shows an example of the formation of space 9 due to the non-adhesive section 8 in the corrugated part 6. In such a structure in which the space 9 is formed due to the non-adhesive section 8, properties such as moisture evaporation, heat transfer and moisture permeability in a fabric base 1 are improved .

As shown in FIG. 4, an uneven surface is formed due to the composite layer 31 in the laminated sheet 30, and the corrugated part 6 is formed due to the uneven surface. As shown in FIG. 2, 3 and 4, the corrugated part 6 is formed by the protrusion 6a and the recess 6b in an uneven surface, and a large area of the corrugated part 6 is formed due to the continuous formation of the protrusion 6a and the recess 6b.

The placement of the elastic element 5 inside the fabric base 1 as described above is a means of forming a corrugated part 6 defined by the protrusion 6A and the recess 6b. The stretchable linear elastic component 5a is used as the elastic element 5, and a rubber thread can advantageously be used as the linear elastic component 5a. An embodiment of the present invention will be described later herein with reference to a case in which a linear elastic component 5a is used as the elastic member 5.

As shown in FIG. 1 and 2, the linear elastic component 5a is designed so that its linear direction of tension coincides with the longitudinal direction of the laminated sheet 30 (x direction in Figs. 1 and 2), and a large number of linear elastic components 5a are parallel to each other with a predetermined gap . Thus, a large number of linear elastic components 5a are placed at regular intervals in the width direction of the laminated sheet 30 (direction y in Figs. 1 and 2), and a large number of rows of linear elastic components are formed.

As shown in FIG. 5, the linear elastic component 5a is located between the first fibrous sheet 2 and the material 4 consisting of fibers. In the present invention, the required number of linear elastic components 5a per unit surface area can be specified, and the necessary gap between the linear elastic component 5a in a series of linear elastic components. In such a configuration, one corrugated portion 6 extending from one end to the other end along the y direction (second direction, which differs from the first direction), in FIG. 1 and 2 will be called the “corrugated part of one row”. The corrugated portion 6 is formed by a large number of rows with a predetermined gap in the x direction, as shown in FIG. 1 and 2. The bonding region of the composite layer 31 and the linear elastic component 5a in the corrugated part 6 will be called the fixation point of the corrugated part. As indicated above, the required number of linear elastic components 5a per unit surface area can be set, but if the number of linear elastic components 5a increases and the gap between the linear elastic components 5a decreases, the number of fixation points of the corrugated part in the corrugated part of one row increases . Thus, the protrusion 6a and the recess 6b in the corrugated part 6 in one row can be formed so that they have a single shape, and this shape can be maintained unchanged. This configuration is preferable since the wrinkling of the corrugated part 6 is prevented, while the flexibility, moisture evaporation ability, heat transfer ability and moisture permeability of the fabric base 1 are improved. From this point of view, it is preferable that the gap between the corrugated part 6, i.e., the size the pitch between the protrusions 6a was 2 mm to 7 mm. More preferably, this step size between the protrusions 6a is from 3.00 mm to 6.25 mm. By reducing the step size between the protrusions 6a, fine corrugation can be formed, which thus improves the appearance. Moreover, since the contact area with the skin on one tab is reduced, contact with the skin is improved, and since the total contact area is increased, the ability to absorb sweat or the like is improved. Furthermore, by increasing the step size between the protrusions 6a, it is possible to properly adjust the elasticity of the rubber thread and reduce the cost of production.

An example of a method for manufacturing a fabric base 1 of the present invention using a rubber thread as a linear elastic component 5a and a hot-melt adhesive as an adhesive will be given below. As will be described below, it is preferable that paper material be used as the fiber material 4, and it is also preferred that a non-woven fabric be used as the first fiber sheet 2 and the second fiber sheet 3. Therefore, a method of manufacturing a fabric base 1 of the present invention will be described later herein with reference to a case in which a paper material is used as the fiber material 4 and a non-woven fabric is used as the first fiber sheet 2 and the second fiber sheet 3. In this case, the non-woven fabric used as the first fibrous sheet 2 is called the first non-woven fabric, and the non-woven fabric that is used as the second fibrous sheet 3 is called the second non-woven fabric.

The paper material used as the fiber material 4 is unwound from a roll. An embossed layer 4a is preliminarily formed on the paper material (see Figs. 4 and 14). The unwound paper material is fed onto an embossing roll and pulled through the roll, thereby performing a mechanical softening process. The mechanical softening process may also include an embossing process using smooth rolls, or the embossing process may be carried out using a gear roll with a large number of protrusions on the surface of the roll. In the case of the last embossing process, a large number of small holes are made in the paper material. After the embossing process, hot melt adhesive is applied to the paper material at regular intervals. Instead of the embossing process, another mechanical process may also be used. At the same time, the second layer of nonwoven fabric, which is used as the second fibrous sheet 3, is unwound from a roll, and the unwound second layer of nonwoven fabric and paper material coated with hot-melt adhesive are joined under pressure using smooth rolls, and both layers are laminated, resulting in a bonded layer is obtained. In the bonded layer, the second nonwoven fabric layer and the paper material are bonded to each other at regular intervals.

A large number of rubber threads are unwound from a roll on which a large number of rubber threads are wound in a parallel row. The unwinding of the rubber thread is carried out with tension under the action of a predetermined tension force. Hot-melt adhesive is applied to the unwinding rubber thread. In this case, the adhesive is applied continuously along the entire length in the longitudinal direction of the rubber thread. The adhesive is also applied to the entire peripheral surface of the rubber thread. At the same time, the first layer of nonwoven fabric, which is used as the first fibrous sheet 2, is unwound from the roll, and the unwound first layer of nonwoven fabric is fed over the bonded layer. The rubber thread is fed in such a way that the rubber thread on which the adhesive has been applied in the manner described above is introduced between the bonded layer and the first layer of the nonwoven fabric. In this case, the rubber thread is fed between the surface of the paper material of the bonded layer and the first layer of non-woven fabric.

The rubber thread passes through a smooth roll when a bonded layer is introduced between the surface of the paper material and the first layer of non-woven fabric. A smooth roll is compressed under pressure, laminated and bonded together by a bonded layer, a rubber thread and a first layer of non-woven fabric. Since the first layer of nonwoven fabric and paper material are bonded so that the rubber thread is between them, both are bonded at regular intervals. Thus, a laminated sheet 30 is made in which the second layer of nonwoven fabric and the paper layer are bonded to each other at certain intervals, and the first layer of nonwoven fabric and the paper layer are bonded to each other at certain intervals. If necessary, the laminated sheet 30 is fed into the embossing roll, and a mechanical softening process is carried out. By carrying out this process, it is possible to further improve the flexibility of the fabric base 1.

Since the manufactured laminated sheet 30 has a large length, the layer is cut to obtain segments of a predetermined length in the longitudinal direction (x direction in Figs. 1 and 2) of the laminated sheet 30. With this cutting, the first layer of nonwoven fabric, the second layer of nonwoven fabric, paper are cut. material and rubber thread. As a result of cutting, the tensile force applied to the rubber thread in a stretched state ceases to act, and the rubber thread is compressed due to the recovery force. As a result of the contraction stresses arising in this case, the force acts in the direction of shortening the length of the composite layer 31, consisting of a first layer of nonwoven fabric, a second layer of nonwoven fabric and paper material. Thus, an uneven surface is formed in the composite layer 31, as a result of which the corrugated part 6 is formed. Thus, it is possible to produce a fabric base 1 with a large area of the corrugated part 6.

The following describes the configuration of the fabric base 1 of the present invention. Due to the action of the recovery force, the linear elastic component 5a is in a compressed state, i.e., in an unstretched state, and a large area corrugated part 6 is formed from the linear elastic component 5a in an unstretched state, extending in a direction (direction along the width of the laminated sheet 30 in Fig. 1 and 2, i.e., the same direction as the direction of y) perpendicular to the longitudinal direction (implies the longitudinal direction of the laminated sheet 30 in Figs. 1 and 2, i.e., the same direction as directed e x), and the laminated sheet 30 is formed of a number of corrugated structure portion in a pattern.

Linear elastic components 5a can be located throughout the entire area inside the laminated sheet 30 or only in part. The advantage of using linear elastic components 5a in the entire area inside the laminated sheet 30 is that due to the uniform elasticity of the fabric base 1 when used as a top layer in disposable underpants or a paper diaper, the fabric base 1 can be held firmly to the body and prevent slipping.

The laminated sheet 30 is elasticized by a linear elastic component 5a located inside the laminated sheet 30. Therefore, if the fabric base 1 formed by the laminated sheet 30 is pulled by hand in the x direction, as shown in FIG. 1 and 2, the linear elastic component 5a stretches, and the fabric base 1 also stretches and expands. If you release your hand in this state, the linear elastic component 5a is compressed by the recovery force, thereby restoring the state of the fabric base 1 with the original dimensions. Due to this possibility of stretching the fabric base 1 when it is used for a disposable textile product, such as underwear and a diaper, the fabric base 1 provides an excellent fit to the body, and also allows the manufacture of dimensionless products.

The fabric base 1 can also be made by laminating two or more laminated sheets 30. In addition, the fabric base can also be made by laminating one, or two, or more laminated sheets 30 with one, two, or more other layers.

The fabric base 1 of the present invention can advantageously be used as a material for a disposable textile product and is convenient as a material having an excellent property that is absent in prior art products. A disposable textile product using a fabric base 1 of the present invention is not limited to a product that is disposed of after a single use, and also includes a product that is reused for a short period of time in accordance with its purpose and purpose of use. A product that is reused can withstand several washing cycles.

The first fibrous sheet 2 and the second fibrous sheet 3 preferably consist of a material having breathability and moisture permeability, and, as noted above, as a fibrous material having such breathability and moisture permeability, a non-woven fabric is preferably used.

As the non-woven fabric of the present invention, a well-known non-woven fabric, which essentially finds wide application, can be used. Thus, a well-known nonwoven fabric having a fibrous structure can be used, in which the fibers are oriented in the same direction or randomly and can be bonded by weaving, splicing, or adhesive bonding. An example of a nonwoven fabric material consisting of fibers includes natural fiber, for example, plant fiber (cellulosic polymer) and animal fiber (protein polymer); refined fiber such as Lyocell and Tencel; regenerated fiber, for example rayon and rayon; semisynthetic fiber, for example acetate fiber; synthetic fiber, for example nylon and acrylic fiber; as well as chemical fiber, for example PP (polypropylene), PE (polyethylene) and PET (polyethylene terephthalate). Such fibers may be used alone or in combination of two or more of them. If necessary, you can use other material.

The nonwoven fabric for use in the first fibrous sheet 2 and the second fibrous sheet 3 can be selected depending on the type or application of the product in which fabric base 1 will be used. For example, if fabric base 1 is used as a disposable textile product for a garment, and the first the fibrous sheet 2 or the second fibrous sheet 3 comes into contact with the wearer's body during wearing, it is preferable that the non-woven fabric to be used as the first fibrous sheet 2 or the second fibrous sheet 3, had such characteristics as flexibility, a pleasant feeling in contact with the skin and the ability to absorb sweat. At the same time, if the first fibrous sheet 2 or the second fibrous sheet 3 is used when placed on the outside of a garment that does not come into contact with the user's body, it is preferable that the non-woven fabric to be used as the first fibrous sheet 2 or the second fibrous sheet 3 , had such characteristics as, for example, water resistance.

An example of a nonwoven fabric suitable for use in the first fibrous sheet 2 or the second fibrous sheet 3 includes a spunbond nonwoven web, a thermally bonded nonwoven web, a hydrowoven nonwoven web, a dry nonwoven web, a wet nonwoven web, a melt nonwoven web, a chemically bonded nonwoven web fabric, needle-punched non-woven fabric, knitting-piercing non-woven fabric and steam jet non-woven fabric. Preferred for use among them are spunbond non-woven fabric, thermally bonded non-woven fabric and hydro-woven non-woven fabric.

The preferred density of the nonwoven fabric that is used for the first fibrous sheet 2 and the second fibrous sheet 3 is from 5 g / m ² to 60 g / m ² , more preferably from 7 g / m ² to 40 g / m ² . The reason for setting the preferred density of the non-woven fabric is due to the fact that if the density is, for example, less than 5 g / m ² , then when a hot-melt adhesive is applied, it may leak onto the surface of the non-woven fabric, and if the density exceeds 60 g / m ² , the thickness increases products, the production efficiency decreases and the manufacturability of the packaging deteriorates. At a density of 7 g / m ² to 40 g / m ^{2, the} bonding strength can be improved by applying the bonding method using hot-melt adhesive simultaneously with the bonding method using heat welding or ultrasonic bonding.

In addition to the non-woven fabric for the first fibrous sheet 2 and the second fibrous sheet 3, you can use other material, provided that this material has air permeability and moisture permeability. For example, an air permeable layer and a moisture permeable layer made of synthetic resin can be used.

If the fabric base 1 of the present invention is used as a material for a disposable garment, as shown in FIG. 13a, the second fibrous sheet 3 is rarely located on the side that is in contact with the skin of the user 200, but if the fabric base 1 is used as a material for disposable bedding (e.g., a sheet), the second fibrous sheet 3 is often located on that the side that is in contact with the skin of the user 200. Thus, if the second fibrous sheet 3 is in direct contact with the human body, it is preferable that the non-woven fabric to be used as the material for the second fibrous sheet 3 has such characteristics as flexibility, a pleasant feeling in contact with the skin and the ability to sweat absorption.

Preferably, the fiber material 4 is made from a raw material having a liquid distribution and transmission ability, and as indicated hereinabove, it is preferable to use paper material such as a distribution and transmission material as such material. liquids.

In addition to the paper material for the fiber material 4, another material can be used in the present invention, provided that it has the ability to distribute and transmit liquid. For example, you can use natural fiber, such as kenaf, bamboo fiber, straw, cotton, cocoon thread and sugarcane fiber. The use of paper material as fiber material 4 is the preferred approach for implementing the present invention, and the case of using paper material as fiber material 4 as an example is discussed below.

As paper material, paper material obtained from raw materials using paper pulp or pulp as the main starting material can be used. Thus, paper material obtained from pulp as a raw material and using the paper manufacturing process can be used.

As the initial pulp, wood pulp, synthetic pulp, waste paper pulp, etc. can be used. In addition, not only natural fiber can be used as pulp, but also regenerated fiber, such as viscose, can be used. Moreover, in the present invention, toilet paper material may also be used as a starting pulp. In this case, for example, you can use the original pulp containing bleached kraft pulp obtained from soft wood, for example from red pine, ayan spruce, Sakhalin fir, Douglas fir, Canadian Tsuga and spruce. You can also use bleached softwood kraft pulp in combination with bleached hardwood kraft pulp, such as beech, oak, birch, eucalyptus, poplar and alder. From the point of view of the problem associated with the cost and ease of production, it is preferable that only bleached softwood kraft pulp is used as the raw material of the pulp.

In the manufacture of paper material using pulp as the main feedstock, the content of the mixed pulp is preferably 30% or more, more preferably 50% or more, and most preferably 80% or more. When mixing the pulp in the above ratio, it is possible to increase the flexibility of the fabric base 1 as a whole, as well as to increase the production efficiency in its manufacture. Moreover, by increasing the ratio of pulp mixing, it is possible to promote the decomposition of waste in the soil or the like after disposal. Consequently, it will be possible to further reduce the burden on the environment and pay more attention to environmental issues. Preferably, a paper layer with a high degradability in water is used as the paper material. It is also preferred that the paper material constituting the fiber material 4 has a single layer configuration including one layer of paper, but it can also have a multi layer configuration including a stack of multiple layers of paper. In the case of a multilayer configuration, the layer may be made of the same or of different materials and may have the same or different thickness. The paper material forming the fiber material 4 can be obtained by mixing pulp with a non-woven fabric. For example, material obtained by mixing pulp with a hydro-woven nonwoven web or by mixing pulp with an air-laid non-woven web can be used as paper material.

The density of the paper material forming the fiber material 4 is preferably from 7 g / m ² to 50 g / m ² . At a density of less than 7 g / m ² it is difficult to achieve a pleasant feeling when wearing a disposable textile product made from a fabric base 1 of the present invention. In addition, it will be difficult to give the product the necessary indicators of moisture evaporation and heat transfer. In addition, the fabric base 1 will have insufficient strength. At the same time, if the density exceeds 50 g / m ² , the thickness of the fabric base increases, the feeling of wearing worsens, and the moisture evaporation and heat transfer rates decrease. Moreover, due to the increase in the thickness of the product, the packaging of products is complicated. More preferably, the density of the paper material is from 10 g / m ² to 30 g / m ² .

As the paper material forming the fiber material 4, color paper can also be used. With this configuration, it is possible to achieve a beautiful aesthetic appearance of the fabric base 1.

Preferably, the paper material forming the fiber material 4 is given a flexible structure that can be obtained by mechanical softening. As a mechanical softening process, an embossing process can be used. In the process of embossing, a pair of rolls can be used for embossing with a large number of protrusions formed on the surface of the rolls. If the embossing process is carried out using embossing rolls, a plurality of small holes are made in the paper material, thereby reducing the strength of the paper structure, and giving the paper material flexibility. The holes may be round, linear or may have the form of a slit. The paper material can likewise be given flexibility in forming an uneven surface formed by a large number of protrusions and recesses without making holes in the paper material.

The embossing rolls used in the embossing process are not limited to the rolls with protrusions formed thereon, and a pair of smooth rolls with a smooth roll surface without protrusions can also be used. The strength of the paper structure decreases when passing the paper material through smooth rolls with the application of pressure from the side of the roll. In this case, the strength of the paper structure is reduced due to the compressive force between the rollers without using the perforation process. The embossing process, which gives the paper material a flexible structure, can also be carried out by combining the embossing process using embossing rolls with protrusions on the surface of the rolls and the embossing process using smooth rolls.

By using the above method of imparting a flexible structure to the paper material, the entire fabric base 1 becomes very flexible, and the feeling of wearing a disposable textile product made from the fabric base 1 can be improved. Thus, by using such a paper material to make the product, the user has a feeling satisfaction due to a pleasant feeling when worn without discomfort.

The effect below is a consequence of giving the paper material a flexible structure. Thus, if the paper material used as the fiber material 4 has a flexible structure, the entire laminated sheet 30 has a flexible structure and, therefore, can easily be deformed. For this reason, when the corrugated part 6 is formed due to the compression stress of the linear elastic component 5a, the laminated sheet 30 is easily deformed, and a corrugated part 6 of a uniform shape with protrusions 6a and recesses 6b is formed. The formation of the corrugated part 6 with protrusions 6a and recesses 6b of a uniform shape increases the flexibility of the entire fabric backing 1, and a disposable textile product made from the fabric backing 1 can provide a much more pleasant wearing experience. In addition, by providing flexibility to the paper material, the fabric base 1 can provide an overall feeling of softness and density.

As will be shown later in this document, the process of reducing the strength of the paper structure by using the embossing process also gives the fabric base 1 an even greater ability to evaporate moisture, the ability to heat transfer and moisture permeability.

As indicated hereinabove, it is preferable that the second fibrous sheet 3 and the fiber material 4 are bonded using a hot-melt adhesive. A suitable example of a hot-melt adhesive is an adhesive based on EVA (ethylene vinyl acetate copolymer), PO (polyolefins), PA (polyamides), SC (silicone synthetic rubber), AKP (acrylic) and PU (polyurethane curable in moist air), and such an adhesive may be used alone or in combination of two or more of them. In addition to the hot-melt adhesive, organic solvent-based adhesives and water-soluble adhesives can be used to bond the second fibrous sheet 3 and the material 4 consisting of fibers.

The second fibrous sheet 3 and the material 4 made of fibers can be bonded by applying adhesive to the entire external surface of their contact, but the above-described method of application at certain intervals is preferred. The advantage of applying at certain intervals compared to applying to the entire outer surface is that in this case the fabric base 1 becomes flexible, and the ability to evaporate moisture, the ability to heat transfer and moisture permeability of the fabric base 1 are improved. The method of intermediate application of adhesive may include a linear , spot, banded, spiral, block and screen application, and such a method can be used individually or in a variety of combinations.

By applying adhesive at defined intervals between the second fibrous sheet 3 and the material 4 consisting of fibers, a non-adhesive portion 8 is formed. The surface area ratio of the non-adhesive portion 8 is preferably from 5% to 85%, more preferably from 10% to 80%, and even more preferably 30% to 75% with respect to the surface area of the second fibrous sheet 3. If the surface area ratio of the non-adhesive portion 8 is within the indicated range, the fabric base 1 exhibits excellent flexibly and the ability to evaporate moisture, the ability to transfer heat and moisture, and you can also achieve an excellent overall feeling of softness and density of the fabric base 1. As a result, the applied amount of adhesive can be limited by the amount necessary to provide a predetermined bond strength, and it is preferable that the amount applied was as small as possible.

As noted above in this document, the linear elastic component 5a is positioned so that the direction of stretching of its fibers coincides with the longitudinal direction (x direction in Figs. 1 and 2) of the laminated sheet 30, a large number of linear elastic components are placed at certain intervals in the direction in width (direction y in FIGS. 1 and 2) of the laminated sheet 30, and a large number of rows of linear elastic components are formed. The parallel placement of the linear elastic components 5a, in which a large number of linear elastic components 5a is placed in parallel in the laminated sheet 30, is also not limited. In FIG. 6a-6j show various arrangements of linear elastic components 5a.

Thus, possible arrangements of the linear elastic component 5a include a parallel arrangement of the straight linear elastic components 5a, as shown in FIG. 6a; an arrangement in which some or all of the straight linear elastic components 5a are arranged parallel to each other with gap sections between them, as shown in FIG. 6b and 6c; an arrangement in which curved and curved linear elastic components 5a are arranged parallel to each other, as shown in FIG. 6d, 6f and 6g; and also the arrangement in which the wavy curved linear elastic components 5a are arranged next to each other in an irregular manner, as shown in FIG. 6e and 6j. Linear elastic components 5a can also be arranged in a mesh pattern, as shown in FIG. 6h and 6i. When arranging a large number of linear elastic components 5a, it is preferable that all linear elastic components 5a have the same elongation, but combinations of linear elastic components 5a with different elongation can also be used. The linear shape of the elastic element 5 is not restrictive, and it is also possible to use a sheet elastic component with a large number of holes or slots to provide a predetermined breathability. Such an elastic sheet component can be obtained using urethane or silicone rubber and natural rubber based rubber material as starting material. In the present invention, it is preferable that the linear elastic component 5a of a linear shape be used as the elastic member 5.

The linear elastic component 5a may be bonded between the first fibrous sheet 2 and the fiber material 4 by bonding the linear elastic component 5a between the first fiber sheet 2 and the fiber material 4 using adhesive that is applied to the linear elastic component 5a, or the linear elastic component 5a may be bonded between the first fibrous sheet 2 and the material 4 consisting of fibers with an adhesive that is applied to the first fibrous sheet 2 and consisting of mate fibers Rial 4. For bonding the linear elastic component, the same adhesive can be used as described above when used for bonding the second fibrous sheet 3 and consisting of fibers of material 4. Preferably, a hot-melt adhesive is used as the adhesive.

The hot-melt adhesive is applied by spraying on the peripheral surface of the linear elastic component 5a, and the applied hot-melt adhesive fastens the first fibrous sheet 2 consisting of fibers material 4 and the linear elastic component 5a so that the linear elastic component is between the first fibrous sheet and the material consisting of fibers . Therefore, it is not necessary to apply a hot-melt adhesive to the first fiber sheet 2 and the fiber material 4. The adhesive can also be applied to the opposite surface of the first fiber sheet 2 and the fiber 4 material so that it is in contact with the linear elastic component 5a , instead of applying adhesive to the linear elastic component 5a.

As indicated hereinabove, the first fibrous sheet 2 consisting of fibers material 4 and the linear elastic component 5a are bonded to each other so that the linear elastic element is inserted between the first fibrous sheet and the fibers consisting of material using a hot-melt adhesive, which was applied by spraying on the peripheral surface of a linear elastic component 5a. However, in the bonded state, part of the hot-melt adhesive penetrates (passes) into the layer of fiber material 4, and an adhesive leakage zone Z is formed, as shown in FIG. 16. Since the adhesive leakage zone Z is bonded to the hot-melt adhesive on the peripheral surface of the linear elastic component 5a, the adhesive leakage zone Z provides a bonding effect for bonding the linear elastic component 5a and the fiber material 4, thereby enhancing the bonding of the linear elastic component 5a and consisting of fibers of material 4 by hot-melt adhesive. Thus, in the material 4 consisting of fibers, a fixing structure is formed due to the adhesive. The resulting advantage is associated with the ability to provide a predetermined bond strength even with a small amount of adhesive applied to the linear elastic component 5a, while the overall strength of the fabric base 1 is increased and a fabric base 1 with high strength can be obtained. In FIG. 16 does not show adhesive located between the second fibrous sheet 3 and the fiber material 4.

The problem associated with the fabric base for a traditional disposable textile product is that when bonding the non-woven fabric using adhesive, the adhesive seeps onto the surface of the fabric base through the gap between the fibers of the non-woven fabric. In contrast, in the case of the fabric base 1 of the present invention, due to the formation of the composite layer 31 and incorporation of the fiber material 4 into the composite layer 31, it is possible to prevent the adhesive from seeping onto the surface of the fabric base as a result of the penetration of the adhesive into the fiber material 4.

As indicated above in this document, in the manufacturing process of the fabric base 1, the laminated sheet 30, which is produced in a continuous mode, is cut to obtain a product with a predetermined length. Due to the long length, the cutting is carried out in such a way as to obtain a predetermined length in the longitudinal direction (x direction in FIGS. 1 and 2) of the laminated sheet 30. Since the linear elastic component 5a is cut during the cutting process, the tensile force ceases to exist, and the linear elastic component 5a is compressed by the recovery force. In this case, under the action of the arising compression stresses, an uneven surface is formed in the composite layer 31. In this case, with a small bonding force of the linear elastic component 5a and the first fibrous sheet 2 and a bonding force of the linear elastic component 5a and the material 4 consisting of fibers, delamination occurs between the linear elastic component 5a, the first fibrous sheet 2 and the material 4 consisting of fibers, and stress compression does not reach the composite layer 31 formed by the first fibrous sheet 2 and consisting of fibers of material 4, bonded to each other by a linear elastic component 5a, resulting in hiccups so-called effect "peeling rubber." As a result of “delamination of the rubber”, the force in the direction of shortening its length does not act on the composite layer 31, and therefore, an uneven surface is not formed in the composite layer 31, which makes it impossible to form the corrugated part 6. In this case, when the hot-melt adhesive forms a leakage zone Z adhesive within the layer of fiber material 4, as shown in FIG. 16, the bonding strength of the fiber material 4 and the linear elastic component 5a is increased, and therefore, it is possible to prevent “peeling of the rubber” when cutting the linear elastic component 5a.

The thickness of the fabric base 1 may be arbitrarily set, and a thin fabric base may be formed. With the formation of a fabric base of small thickness, it is possible to increase the breathability and water permeability of a disposable textile product made using a fabric base 1 and provide a pleasant feeling when worn.

When using paper material as fiber material 4, an embossed layer 4a can be formed in the paper material as necessary, as shown in FIG. 4 and 14. As shown in FIG. 14, the embossed layer 4a is formed in the fiber material 4 on the side facing the second fibrous sheet 3. In an embodiment of the present invention, the embossing can be performed on a paper material and not on a nonwoven fabric. Therefore, it is possible to apply a clear image simply and efficiently. As a result of this, various designs and images can be applied efficiently and effectively. In particular, by choosing, if necessary, the design or pattern to be applied to the paper material, the non-woven fabric for use in the second fibrous sheet 3, and the method for forming the adhesive layer 7, it is possible to obtain a one-piece fabric base 1 with excellent design and aesthetic properties. For example, an image, color, pattern, photograph (hereinafter referred to as the “image”) are examples of design and pattern for applying to paper material.

The image can be applied to paper material used as material 4 consisting of fibers, for example, by inkjet printing, flexographic printing and gravure printing. The surface of the embossed layer 4a may be varnished or treated to prevent discoloration, or a binder may be applied to its surface. An example of a binder is a well-known material such as PVA (polyvinyl alcohol), CMC (carboxymethyl cellulose), EVA (ethylene vinyl acetate copolymer), acrylic and varnish. Processed ink can also be used to prevent discoloration.

Preferably, the embossed layer 4a is formed by flexographic printing. The advantage of the flexographic printing method is that the contact surface between the plate and the paper material may be small, and slight pressure may be used in the printing process. Therefore, the paper material can easily be detached from the plate. This method has a particular advantage in the formation of the embossed layer 4a with a small thickness of the paper material. Moreover, in flexographic printing, many different types of ink can be used, and in this aspect, the process is less dependent on the viscosity of the ink than the inkjet process, in which ink is supplied through a nozzle or the like. If an image is applied to the embossed layer 4a, the image to be applied to the plate can be applied as an image with an elongated design, depending on the degree of stretching of the laminated sheet 30 in the direction of stretching / compression (x direction in Fig. 2) of the linear component 5a. Upon the transition of the linear elastic component 5a from the stress state to the free state, the design of the initial shape (design of an elongated shape) appears. In this case, the elongation factor of the image to be applied in the x direction is determined by the stretch / compress coefficient of the linear elastic component 5a. For example, printing can be done by increasing the length of the image relative to the original target design (non-elongated shape) with a ratio of from 1.1 to 3.5.

A three-dimensional image can be applied to the embossed layer 4a by forming a plurality of recesses or protrusions on the paper material during the embossing process, and an image can be obtained whose design differs depending on the angle of view. Moreover, as shown in FIG. 14, the embossed layer 4a can be formed so that it is located in the space 9, and the embossed layer 4a can be formed in places covered by the adhesive layer 7. By combining such an embossed layer 4a, it is possible to expand the variety of designs that can be used in the product. If the proportion of space 9 is large, the embossed layer 4a applied to the product will appear somewhat blurred, and with a small proportion of the space 9, the embossed layer 4a applied to the product will be clearly visible.

Since the embossed layer 4a is visible externally through the second fibrous sheet 3, various designs or textual information can be applied efficiently and effectively to the fabric base 1. In order for the embossed layer 4a to be clearly visible from the outside and to obtain a product with high aesthetic characteristics, it is preferable to use a non-woven fabric as the second fibrous sheet 3.

If, as shown in FIG. 13a, in a disposable textile product made using the fabric base 1 of the present invention, the sweat 300 adheres to the skin 200, then when moving the body, as shown in FIG. 13b, the corrugated portion 6 erases the sweat 300, and the sweat 300 thus erased is absorbed by the fiber material 4 (paper material) in the composite layer 31 (see FIG. 4). Moreover, the sweat 300 that has not been erased evaporates into the space formed by the corrugated portion 6 and is likewise absorbed into the fiber material 4 (paper material), as shown in FIG. 13s Accordingly, the fabric base 1 does not directly come into close contact with the skin 200 through the sweat 300, and the sweat 300, which is absorbed by the fiber material 4 (paper material), effectively evaporates outward (Fig. 13c). For this reason, the sweat 300 evaporates quickly, there is no sticky sensation created by the 300, which provides comfort when wearing the product.

When using the fabric base 1 of the present invention in a disposable textile product, various additives can be added to the fabric base 1 depending on the characteristics of the product. Examples of the additive introduced into the fabric base 1 include a deodorant, an insect repellent, a perfume, a hydrophobic agent, an anti-fouling agent, an antibacterial agent and a softener, and such agents can be used individually or in combination of two or more of them. When introduced into the fabric base 1, the additive can be individually added to any of the first fibrous sheet 2, the second fibrous sheet 3, or material 4 consisting of fibers, or it can be added to two or more of them. The additive may be added by applying the additive to the surface of the first fibrous sheet 2, the second fibrous sheet 3, and the material 4. When adding the additive to the first fibrous sheet 2 and the second fibrous sheet 3, the additive may be pre-mixed with the fiber that will form the basis of such layers . In the case of adding to the paper material, which is used as a material consisting of fibers 4, the additive can be introduced into the water in advance during the paper making process, thereby ensuring the inclusion of the additive in the paper. Moreover, if an embossed layer 4a is formed on the fabric base 1, the additive can be mixed in advance with the ink for printing, after which printing is carried out using ink for printing with the additive.

Such insect repellents can be used individually or in combination of two or more of them.

Specific fragrance examples include (vegetable) essential oils of fruits, such as orange, lemon, lime, and peach; flowers, such as roses and lavender; as well as peppermint and sandalwood. The aromatic component is usually prepared on an oil basis or it is soluble in water or alcohol. Examples of oil-based fragrances include phenylethyl alcohol, linalool, jasmone, hexyl cinnamaldehyde, α-limonene, α-pinene, bromstyrene, citronellal, chloral, terpineol, menthol and cinnamic acid. These aromatic fragrances can be used individually or in combination of two or more of them.

As an antibacterial agent, a carbendazim derivative with antimicrobial properties can be used.

Examples of suitable anti-fouling and softening agents include cationic surfactants, for example, alkyl quaternary ammonium salts, which are widely used in hair rinses and fabric softeners. Examples of such cationic surfactants include dicocoyldimethylammonium chloride and alkyltrimethylammonium chloride. Glycerin, propylene glycol, butylene glycol, dipropylene glycol and liquid paraffin can also be used as anti-fouling and softening agents. These anti-fouling agents and softeners can be used individually or in combination of two or more of them.

The fabric base 1 of the present invention is used as a material for a disposable textile product and is particularly convenient as a composite material for disposable underwear, for example, disposable underpants and disposable diapers. Other examples of disposable textiles that can be made using the fabric base 1 of the present invention include underwear or a T-shirt 100, for example, shown in FIG. 7, topic 101, for example, shown in FIG. 8, a belt for the abdomen 102, for example, shown in FIG. 9, a raincoat 103 similar to the raincoat shown in FIG. 10, a bandage 104, which is used for various parts of the body, for example, palms, hands, hands, knees, and ankles, as shown in FIG. 11a-11e, as well as a bandage 105, for example, shown in FIG. 12. In addition, training clothing, sportswear, sweat-absorbing underwear, swimwear, and homewear may be used as a disposable textile product (illustrations are not shown for such examples). If the fabric base 1 of the present invention is used for a hat as a disposable textile product, it can be worn if the material 4 made of fibers is saturated with water. In this case, the evaporation of water creates the effect of cooling the user's head.

The fabric base 1 of the present invention can also be used as a composite material for a diaper bag designed to store used diapers, various sanitary products for women, various disposable items of clothing that will be used for hiking and outdoor activities, cooling or warming dressings, towels and disposable clothing, bedding, leggings, bras, shorts, bathrobes, leggings, headbands, hair bands, massage clothes and hospital clothing allocated to patients and visitors in a hospital, hotel, etc.

In FIG. 17 shows an embodiment in which disposable underwear 10 as a disposable textile product is fabricated using the fabric backing 1 of the present invention. The underwear 10 shown in FIG. 17 is a diaper of the type of so-called panties, which is used when worn on the body of the user P. Such underwear comprises a part 12 adjacent to the body, which is made of the fabric base 1 of the present invention, covers the entire body of the user P and includes a portion providing light pressure on the lower abdomen, as well as the section 14 of the connection with the belt, which is located on the upper side of the body adjacent to the body part 12, includes an elastic element, for example, rubber, and is fixed around user я s overalls P. Inside the body 12 adjacent to the body (the side in contact with the body), an elastic layer 16 is inserted between the front and rear sections of the body 12 adjacent to the body, and an absorbent 18 is fixed inside the elastic layer 16 (the side in contact with the skin of the user P) 18 absorption of body secretions.

As indicated hereinabove, the underwear 10 shown in FIG. 17, functions as a diaper and can be used as a diaper for infants and a diaper for adults. A diaper that uses the fabric base 1 of the present invention provides a softer feel than a traditional diaper, has excellent moisture evaporation ability, heat transfer and moisture permeability, and advantageously gives a feeling of coolness. Underwear 10 using the fabric base 1 of the present invention provides the same wearing experience as ordinary underwear (underpants), but its distinctive property, which is not characteristic of a traditional disposable diaper, is that it provides only a slight feeling resistance when using. Thus, underwear can be used with confidence without any sense of resistance as disposable underwear for patients with risk of incontinence, older women in labor, and women during menstruation. When using paper material as the fiber material 4, which is part of the fabric base 1 of the present invention, it is possible to prevent the formation of static electricity during wear, since the paper material is practically not electrified by friction.

Below, the document will describe the functioning of the fabric base of the present invention, made in accordance with the above description, and a disposable textile product made using the fabric base of the present invention. Since the corrugated part 6 is formed in the laminated sheet 30 of the fabric base 1 of the present invention, its effect provides softness of the fabric base in contact with the skin, and flexibility is characteristic of the entire fabric base.

Moreover, the laminated sheet 30 as a laminated composite material contains a first fibrous sheet 2 having air permeability, a second fibrous sheet 3, which also has air permeability, and a fiber distribution material 4 having liquid distribution. In this configuration, the fiber layer having breathability and the fiber layer having liquid distribution ability are adjacent to each other. In the laminated sheet 30, a composite layer 31 is formed in which a fiber layer having breathability and a fiber layer having liquid distribution ability are laminated adjacent to each other. When wearing a disposable textile product containing a fabric base 1 of the present invention, for example, in such a way that the first fiber sheet 2 is in contact with the skin of the body, sweat secreted by the body is absorbed by the layer of fiber material 4 through the first fiber sheet 2, and sweat diffuses into the layer of material 4. The diffused and substantially propagated inside the layer sweat evaporates outward through the second fibrous sheet 3. In this way, an effective and sweat man and there is no local sweat retention in an area that is in contact with a fabric substrate.

Thus, since the air-permeable functional layer and the liquid distributing functional layer are adjacent to each other in the composite layer 31 of the laminated sheet 30, the air-permeable functional layer and the liquid distributing functional layer interact, and due to this interaction, the evaporation efficiency is significantly increased. Thus, since the passage of moisture through the breathable functional layer and the passage of moisture through the liquid distributing functional layer is continuous, and they are adjacent to each other, a very high efficiency of sweat absorption and drying is ensured. In addition, since the corrugated portion 6 formed on the laminated sheet 30 is formed with an uneven surface formed by the composite layer 31, the breathable functional layer and the liquid distributing functional layer in the composite layer 31 are irregular in shape, thereby providing a large surface area. As a result of this, the evaporation efficiency of sweat from the composite layer 31 is significantly increased.

The fabric base 1 of the present invention is characterized by excellent heat transfer ability and can effectively dissipate heat generated by the body. The heat generated by the body is transferred through the first fibrous sheet 2 to the layer of material 4 made of fibers, and such heat diffuses in the layer of material 4 made of fibers. The material 4 made of fibers has the ability to distribute liquid, and due to this ability to distribute liquid, consisting of fiber material simultaneously exhibits heat transfer ability. The heat diffused and propagated in the layer is dissipated outward through the second fibrous sheet 3. Thus, the heat is efficiently dissipated and is not retained between the body and the fabric 1. This excellent heat transfer ability can manifest itself in the fabric 1 of the present invention, since, as described above the evaporation effect of sweat, the laminated sheet 30 contains a composite layer 31, in which a fiber layer having breathability, and a fiber layer having liquid distribution ability, l are adjacent to each other, and the breathable functional layer and the liquid distribution functional layer interact with each other in the composite layer 31.

The fabric base 1 of the present invention also has excellent moisture permeability. In a composite layer formed by laminating a plurality of composite materials, moisture permeability typically decreases with an increase in the number of constituent layers. In the present invention, a layer of material is added, namely fiber material 4, therefore, the number of constituent layers is increased compared to a conventional laminate obtained by laminating two fibrous sheets. However, in the fabric base 1 of the present invention, there is no decrease in moisture permeability compared to a traditional product with good moisture permeability, and the same moisture permeability can be manifested as in a traditional product with good moisture permeability. The ability to maintain good moisture permeability, despite the increase in the number of constituent layers, can be considered as a specific effect of the present invention. The possibility of such an effect can be associated with the configuration described above, in which the laminated sheet 30 contains a composite layer 31, in which a fiber layer having breathability and a fiber layer having liquid distribution are laminated adjacent to each other, and a breathable functional layer and a liquid distributing functional layer interact with each other in the composite layer 31.

If paper material is used as the material 4 consisting of fibers in the fabric base 1 of the present invention, and the process of reducing the strength of the paper structure is carried out by embossing the paper material in the manner described above, it is possible to significantly increase the interaction of the breathable functional layer and the liquid distribution functional layer, and also further increase the ability to evaporate moisture, the ability to heat transfer and moisture permeability.

Moreover, by printing on a fabric basis 1 in an embodiment of the present invention, it is possible to efficiently and effectively apply a variety of design or text information. The fabric backing 1 of the present invention provides an excellent overall feeling of softness and density, as well as flexibility, and can efficiently and effectively impart a variety of functions while using the texture that is characteristic of the fabric backing material itself. Another advantage of the fabric base 1 of the present invention is the simplicity and low cost of its manufacture.

EXAMPLE

Below in this document will be presented a more detailed description of the present invention with reference to a specific example of a tensile composite layer, which is used in the present invention.

(Example 1)

A spunbond nonwoven fabric was used as the breathable layer, paper with a pulp content of 100% (toilet paper sheet, density 18 g / m ² ) was used as a liquid distributing fibrous sheet, without printing, and urethane rubber with diameter 620 decitex. As an example 1, we took a layer material with a total density of 38 g / m ² , which was obtained by bonding paper and urethane rubber using a hot-melt adhesive (the total density of a hot-melt adhesive is 1.2 g / m ² ) placed between two layers of a nonwoven fabric.

(Comparative example 1)

As comparative example 1, a layer material with a total density of 20 g / m ^{2 was} taken, which was obtained by using a non-woven fabric and urethane rubber, as in example 1, with the introduction of urethane rubber between each of the layers of the non-woven fabric and its bonding using hot-melt adhesive (the total density of the hot-melt adhesive is 1.2 g / m ² ).

(Comparative example 2)

As comparative example 2, we took the traditional layer material with a total density of 24 g / m ² , which was obtained using a spunbond nonwoven fabric on the front surface and the back surface, with the introduction of urethane rubber with a diameter of 620 decitex between each of the layers of the nonwoven fabric.

(Comparative example 3)

As comparative example 3, we took the traditional layer material with a total density of 22 g / m ² , which was obtained using a thermally bonded non-woven fabric on the front surface and the back surface, with the introduction of urethane rubber with a diameter of 620 decitex between each of the layers of the non-woven fabric.

(Comparative example 4)

As a comparative example 4, we took another traditional layer material with a total density of 22 g / m ² , which was obtained using a thermally bonded nonwoven fabric on the front surface and the back surface, with the introduction of urethane rubber with a diameter of 620 decitex between each of the layers of the nonwoven fabric.

(Comparative example 5)

As comparative example 5, we took the traditional layer material with a total density of 20 g / m ² , which was obtained using a thermally bonded non-woven fabric on the front surface and the back surface, with the introduction of urethane rubber with a diameter of 620 decitex between each of the layers of the non-woven fabric.

First, moisture absorption and quick drying ability (evaporation ability), as well as the moisture permeability of the layer material in Example 1 and Comparative Examples 1-5 were evaluated.

Moisture absorption and quick drying ability were evaluated in the combined tests of moisture absorption and quick drying ability as part of the evaporation test (II) (Boken standard BQEA028).

A test sample with a diameter of approximately 9 cm was made from the materials of the layer of Example 1 and comparative examples 1-5, and the mass (W) of each test sample and Petri dish was measured. Then 0.1 ml of water was added dropwise to the cup, a test sample was placed on it, and the mass (W0) was measured. The sample cup was kept under standard conditions (20 ° C, relative humidity 65%) and mass (Wt) was measured at predefined time intervals (5 min, 10 min, and then at each interval from 10 min to 60 min). Then, the transpiration value (%) for each predetermined period of time was calculated based on the measured mass W, W0, Wt in accordance with the following equation (1).

The amount of transpiration (%) = {(W0 - Wt) / (W0 - W)} × 100 ... (1)

The results are presented in table 1.

Table 1

The amount of transpiration (%) 5 minutes 10 minutes 20 minutes 30 min 40 min 50 min 60 min Example 1 9.8 20.9 43 62.9 78.7 88.6 94.7 Comparative Example 1 3.8 6.8 12.9 17.7 23.3 28.9 35,2 Reference Example 2 4.3 8.1 15.3 20,4 27.5 33 39.5 Reference Example 3 1.7 3 6.3 7.9 10,2 12.8 18.3 Reference Example 4 0.7 3,5 5.7 9.5 11,4 15,2 17.9 Reference Example 5 1.7 3.4 5.2 9.8 12.6 15.4 15.3

The results of measuring the transpiration value, which are presented in table 1, clearly show that in comparative examples 3-5, the transpiration value is 20% or less even after 60 minutes, and in comparative examples 1 and 2, the transpiration value is less than 20% after 20 minutes and 40% or less even after 60 minutes, while in Example 1 the transpiration value exceeds 20% after 10 minutes, the transpiration value exceeds 40% after 20 minutes, and then the transpiration value exceeds 60% after 30 minutes, the transpiration value exceeds 75% after 40 min, transpiration value and exceeds 85% after 50 minutes, and transpiration exceeds 90% after 60 minutes.

In accordance with the Boken standard BQEA028, which is used as an assessment indicator, the preferred transpiration value 20 minutes after the start of testing should be from 50% (inclusive) to 40% (inclusive) for a knitted product in the case of sports applications and from 40% ( inclusive) up to 30% (inclusive) for a knitted product in the case of general applications.

Thus, since the layer material from Example 1 allows one to obtain a transpiration value of 40% or more, it can be said that such a material can be comfortably worn in sports applications and in general applications.

As follows from the above, the disposable garment of the present invention, which uses the material of the layer of example 1, has a very high ability to absorb moisture and the ability to quickly dry (evaporation).

Then, the moisture permeability was checked according to method A-1 (method using calcium chloride) according to JIS-L1099 (2012) and the moisture permeability (g / m ² ⋅ h) was measured and evaluated.

Moisture permeability is defined as the value obtained by calculating the mass (g) of water vapor passing through the textile product for 1 m ² × 1 h of textile product at standard temperature and humidity.

A test sample was taken from the layer material from Example 1 and comparative examples 1-5 in accordance with JISL0105 (6.3) (a fabric sample and its test sample).

A device and material were prepared, such as a moisture-permeable cup, a hygrostat thermostat, a round plate and a moisture absorber in accordance with the method using calcium chloride, and then tested.

First, approximately 33 g of the moisture absorber was placed in a moisture-permeable cup, which was heated to approximately 40 ° C, the moisture-permeable cup was shaken to ensure uniform distribution of the material, the surface was leveled with a spatula, and the distance between the moisture absorber and the lower surface of the test specimen was adjusted to 3 mm .

Then, three test samples with a diameter of approximately 70 mm were taken in accordance with JISL0105 (6.3) (a fabric sample and its test sample) from the material of the layer from example 1 and comparative examples 1-5.

Each test specimen was placed concentrically with a moisture-permeable cup, so that the surface of the test specimen was facing the moisture absorber, then a gasket and ring were installed and fixed with a wing nut, after which the surface on the attachment side was sealed with vinyl self-adhesive adhesive tape to form a test specimen . The test sample was placed inside a hygrostat thermostat at a temperature of 40 ° C ± 2 ° C and relative humidity (90 ± 5)%, so that the air velocity at a distance of about 10 mm from the test sample did not exceed 0.8 m / s. The test sample was removed after 1 h and its weight (a1) was immediately measured with an accuracy of 1 mg. After measurement, the test sample was again placed in the same place in the hygrostat, the test sample was removed after 1 h and the mass (a2) was measured immediately with an accuracy of 1 mg. Then, the moisture permeability of PA1 (g / m ² · h) was calculated from the measured masses a1 and a2 using the following equation (2).

Moisture permeability PA1 (g / m ² ⋅h) = (a2 - a1) / SA1 ... (2)

In equation (2), a2 - a1 represents the change (g / h) in the mass of the test sample in 1 hour, and SA1 represents the area of moisture penetration (m ² ).

The test result was rounded to the nearest whole according to the method of three average JISZ8401 (rounding method). The results obtained are shown in table 2.

table 2

Moisture permeability (g / m ² ⋅h) Example 1 564 Comparative Example 1 563 Reference Example 2 435 Reference Example 3 496 Reference Example 4 526 Reference Example 5 433

The results reflecting moisture permeability, which are presented in table 2, clearly show that in comparative examples 2, 3 and 5, the moisture permeability is 500 g / m ² ⋅ h or less, in comparative example 1-563 g / m ² ⋅ h, and in comparative example 4-526 g / m ² ⋅ h. At the same time, in example 1, the moisture permeability is 564 g / m ² ⋅ h, which is more than the values presented in the comparative example.

From the above it follows that the functional material of the fabric base of the present invention is highly stable and has good moisture permeability.

The results of the assessment of moisture permeability and the results of the assessment of transpiration after 20 minutes and after 60 minutes for example 1 and comparative examples 1-5 are presented in table 3.

The moisture permeability evaluation results and the evaporation evaluation results shown in Table 3 clearly show that the functional material of the fabric base of the present invention, which was used in Example 1, surpasses the functional material of the fabric base from comparative examples 1-5 in both moisture permeability and due to its ability to evaporate, and also allows for higher moisture permeability and transpiration.

The result presented above in this document clearly demonstrates the effect of the functional material of the fabric base for a disposable product and a disposable textile product in accordance with the present invention.

Of course, the present invention is not limited to the embodiment described above, and includes all embodiments that achieve the objectives of the present invention.
