Japanese Patent Laid-Open No. 10-323372 JP 2008-194498 A JP 2002-345873 A

  The present invention has been made to solve and achieve the above-described problems, and an object of the present invention is to further improve waterproofness.

  For this reason, in the sheet production method of the present invention, a sheet-like first laminated plastic layer is stacked on a woven flat first cloth, and these are pressed and heated to obtain the first cloth and the first cloth. One laminated plastic layer was stuck so as not to be separated and laminated.

  In the sheet production method of the present invention, a sheet-like first laminated plastic layer is superimposed on a woven flat first cloth, and the woven flat second cloth is laminated on the first laminated plastic layer. The layers were pressed and heated, and the first cloth, the first laminated plastic layer, and the second cloth were brought into close contact so as not to be separated and laminated.

  Further, in the sheet production method of the present invention, a sheet-like first laminated plastic layer is stacked on a woven flat first cloth, and the side opposite to the direction where the laminated plastic layer of the first cloth is stacked. A film-like second laminated plastic layer is stacked on one side of the film, and these are pressed and heated to adhere the first laminated plastic layer, the first cloth and the second laminated plastic layer so as not to be separated and laminated. did.

  Such a 1st laminated plastic layer or a 2nd laminated plastic layer improves waterproofness more. In particular, even if a part of the first laminated plastic layer or the second laminated plastic layer breaks due to washing, use for many years, or other reasons, the pile on the opposite side of this laminated plastic layer will leak before the breakage point. Or, it can absorb enough water after leaking out, preventing leakage, and the pile keeps air permeability and does not accumulate moisture.

  Further, of one side or both sides of the first fabric or the second fabric, the surface to which the first laminated plastic layer or the second laminated plastic layer is adhered is the natural fiber, plant fiber, animal fiber, regenerated fiber, or these A larger amount of the synthetic fiber or a yarn made of a semi-synthetic fiber containing these synthetic fibers was exposed than a yarn made of a semi-synthetic fiber containing fibers.

  Thereby, the first laminated plastic layer or the second laminated plastic layer is firmly adhered to the first fabric or the synthetic fiber of the second fabric by the pressurization and heating, and is washed, used for many years, etc. For this reason, the first laminated plastic layer or the second laminated plastic layer is difficult to peel from the first cloth or the second cloth.

The back surface of a sheet (1st embodiment) is shown. The surface of a sheet (1st embodiment) is shown. The side of a sheet (1st embodiment) is shown. The expanded cross section of the surface of the 1st pile 4 ... of a sheet | seat (1st embodiment) is shown. The expanded cross section of the surface of the 2nd pile 5 ... of a sheet | seat (1st embodiment) is shown. The side of a sheet (second embodiment) is shown. The side of a sheet (3rd embodiment) is shown. A sheet production method / production apparatus (first embodiment) is shown. A sheet production method / production apparatus (second embodiment) is shown. A sheet production method / production apparatus (third embodiment) is shown.

(1) Back surface of sheet (first embodiment) FIG. 1 shows the back surface of the sheet (first embodiment). The dimensions of the human body on which this sheet is used are also changed depending on the size of the human body that abuts, such as infants, children, adults, Orientals, Westerners, obese bodies, and slimy bodies. In the present embodiment, an average Oriental adult is assumed.

  The woven first cloth 1 is flat and rectangular, and has a size of several tens of centimeters × several tens of centimeters, for example, 150 cm × 90 cm. The weaving method is a plain weave or the like that weaves a towel having a large number of piles, and a first pile 4 and a second pile 5 described later are formed on the surface (one side).

  The first laminated plastic layer 2 is formed on the back surface (one side on the opposite side) of the first cloth 1 and on the central portion of the flat surface without the irregularities where the first pile 4 and the second pile 5 are not formed. Are stacked in a square shape. The first laminated plastic layer 2 is flat, has a substantially uniform thickness, and has a square shape of several tens of cm × several tens of cm, for example, 90 cm × 90 cm. Is formed.

  Both edges in the width direction of the first laminated plastic layer 2 reach and coincide with both edges in the width direction of the first cloth 1. The first laminated plastic layer 2 is heated, for example, by superposing a thermoplastic resin sheet of plastic such as polyester, polyurethane, polyethylene, polystyrene, polypropylene, polyethylene, polyvinyl chloride on the first cloth 1, By laminating or the like, the first cloth 1 is bonded and adhered to the back surface of the first fabric 1.

  This first laminated plastic layer 2 is firmly waterproofed so that moisture does not leak under the first cloth 1. Outside the both edges in the longitudinal direction of the first cloth 1 of the first laminated plastic layer 2, there are no plastic laminated areas 3, 3 where there is no first laminated plastic layer 2 and the surface of the first cloth 1 is exposed. It has become.

  The plastic non-regions 3 and 3 have a rectangular shape of several tens cm × several tens cm, for example, 30 cm × 90 cm. Thus, since there are the plastic non-regions 3 and 3 without the first laminated plastic layer 2 at both ends in the longitudinal direction of the first cloth 1, the air permeability is improved. No pile is formed in the plastic-free regions 3 and 3.

  Further, even when a person on the first cloth 1 moves or sleeps, the leaked water hardly moves to the edge in the longitudinal direction of the first cloth 1. There may be plastic-free areas 3, 3 without the plastic layer 2. Even if the water leaked to the first laminated plastic layer 2 moves to the edge of the first laminated plastic layer 2, it can be absorbed by the plastic-free areas 3 and 3 and move out of the first cloth 1 (sheet). There is no end to it.

  On the other hand, the plastic non-regions 3 and 3 are not formed at both ends in the width direction of the first laminated plastic layer 2. This is because the center portion of the first cloth 1 of the sheet is recessed in the longitudinal direction along the shape of the person, and both ends in the width direction of the first cloth 1 are raised, so that the leaked moisture is at both ends in the width direction. It is difficult to reach.

  If a person on the first cloth 1 moves or sleeps and turns over, even if the leaked water reaches the end of the first cloth 1 in the width direction, it can be waterproofed. In addition, the plastic no area | regions 3 and 3 may be formed also in the both ends of the width direction of the 1st cloth 1. FIG.

(2) Surface of Sheet (First Embodiment) FIG. 2 shows the surface of the sheet (first embodiment). A large number of first piles 4 are formed on one surface (front surface) of the first cloth 1 on the opposite side of the first laminated plastic layer 2 over the entire flat surface. The first piles 4 are formed when the first cloth 1 of the towel is woven.

  The second pile 5 is formed on the opposite side of the first plastic layer 2 on the opposite side of the fabric 1 on the opposite side of the first pile 4. ... are formed over the entire surface. The second piles 5 are also formed when the first cloth 1 of the towel is woven.

(3) Section of Sheet (First Embodiment) FIG. 3 shows a side surface of the sheet (first embodiment). The height of the first piles 4 is, for example, about 1 mm to 10 mm, and the height of the second pile 5 is, for example, about 0.5 mm to 5 mm. This is an example and may be other heights.

  The height of the first piles 4... Is several times to several tens of percent larger than the height of the second piles 5. As a result of being large / high / large, the thickness of the first piles 4... Is several times to several tens of percent larger / thick than the thickness of the second piles 5.

  This is the same whether a person having a weight of 10 kg to 100 kg rides on the sheet and is under pressure, or no pressure is applied. Moreover, it can be said that the amount per unit area of the first piles 4 is larger than the amount per unit area of the second piles 5 due to the large / high / large amount. With such a structure, the surface of the first pile 4... Has higher water absorption than the surface of the second pile 5.

  The first laminated plastic layer 2 has a thickness of 0.1 mm to 1 mm. The thickness of the first laminated plastic layer 2 is smaller than the height of the first piles 4. Thereby, the soft cushioning properties of the first piles 4 are not impaired, and the comfort of the sheets by the first piles 4 can be maintained.

  Further, the thickness of the first laminated plastic layer 2 is smaller than the height of the second pile 5. Thereby, it becomes difficult to feel the level difference of the first laminated plastic layer 2 at the boundary of the edge of the first laminated plastic layer 2, and the comfort of the sheet at the boundary of the first laminated plastic layer 2 can be maintained.

  The first pile 4 on the back surface of the first cloth 1 of the first laminated plastic layer 2 has a higher density / larger amount of pile than the second pile 5 on the back surface of the other plastic non-regions 3 and 3. / Because it is high / large, even if a part of the first laminated plastic layer 2 is damaged due to washing, use for many years, or other reasons, the first pile 4 on the opposite side of the first laminated plastic layer 2 The water before and after leaking from the damaged portion can be sufficiently absorbed, and the leakage is prevented, and the first pile 4 and the second pile 5 keep the air permeability and do not collect moisture.

  Further, the thickness of the first cloth 1 is about 1 mm to 5 mm, excluding the first pile 4 and the second pile 5, and when a pressure of 10 g to 1 kg / square cm is applied, the thickness is 0.1. It is about 1 mm to 2 mm. Therefore, the thickness of the first laminated plastic layer 2 is several tenths to several times the thickness of the first cloth 1. Thereby, the waterproofness of the 1st cloth 1 can be improved.

  The first laminated plastic layer 2 is adhered and bonded only to the warps 11 ..., 12 ..., wefts 13 ... exposed on the surface of the first fabric 1, and is adhered and laminated on one side of the first fabric 1, and further below. The first pile 4 has not been reached. Thereby, the soft cushioning properties of the first piles 4 are not impaired, and the comfort of the sheets can be maintained.

  When laminating and laminating the first laminated plastic layer 2, the first cloth 1 is laminated with the film of the first laminated plastic layer 2 before adhesion facing down and on the first pile 4. Then, it is pressed and heated by a rolling roller or the like, and the first laminated plastic layer 2 is bonded to the first cloth 1 and brought into close contact therewith.

  At this time, the temperature of the rolling roller is determined according to the melting temperature of the type of material used as the first laminated plastic layer 2. If the melting temperature of the material is low, the temperature of the rolling roller is also lowered, the pressure of the rolling roller is increased, or the speed of the rolling roller is decreased, and if the melting temperature of the material type is high, the temperature of the rolling roller Is increased, the pressure of the rolling roller is decreased, or the speed of the rolling roller is increased.

  The temperature, pressure, and speed are set, for example, at a temperature of 50 to 200 degrees, a pressure of 1 to 100 g / square cm, and a speed of 1 to 50 cm / second, depending on the material type of the first laminated plastic layer 2 And the optimum one is determined. The first laminated plastic layer 2 is bonded and adhered in such a manner that the first laminated plastic layer 2 does not reach the first piles 4.

(4) Section of Sheet (First Embodiment) FIG. 4 shows an enlarged section of the surface of the first pile 4 of the sheet (first embodiment). FIG. 4 is a cross section along the direction of the warps 11... 12, and the first fabric 1 is viewed from the width direction / lateral direction.

  The first fabric 1 is woven in a plain weave with bamboo fiber warp yarns 11... 12, and bamboo fiber weft yarns 13..., And a first pile 4 is formed for every two weft yarns 13. The first fabric 1 is woven. The first piles 4 are not formed on the warp yarns 12 but are ground yarns (ground warp yarns). Since this first cloth 1 gives priority to water absorption, it is relatively uneven. The first piles 4 are formed and woven, one for every two wefts 13.

  FIG. 5 shows an enlarged cross section of the surface of the second pile 5 of the sheet. FIG. 5 is a cross section along the direction of the warps 11... 12, and the first fabric 1 is viewed from the width direction / lateral direction.

  The first fabric 1 is woven in a plain weave with bamboo fiber warp yarns 11 ..., 12 ... as well as bamboo fiber weft yarns ..., and a second pile 5 is formed for every four weft yarns ... One cloth 1 is woven. The second piles 5 are not formed on the warp yarns 12 but are ground yarns (ground warp yarns). Since this first cloth 1 gives priority to water absorption, it is relatively uneven. The second piles 5 are formed and woven one by one for every four wefts 13.

  The warps 11 ..., 12 ..., the wefts 13 ... on the surface of the first pile 4 ... are the same as the warps 11 ..., 12 ..., the wefts 13 ... on the surface of the second pile 5 .... That is, the warp yarns 11 ..., 12 ... woven on the surface of the first pile 4 ... are woven as they are on the surface of the second pile 5 ... to form the first pile 4 ... on the same warp yarn 11 ... Two piles 5 are formed. However, only the weaving of piles 4 ... 5 ... can be changed.

  Thus, the number of the first piles 4 per unit area is larger than the number of the second piles 5 per unit area. With such a structure, the surface of the first pile 4... Has higher water absorption than the surface of the second pile 5.

  In addition, the ratio of the wefts 13 ... in which the first piles 4 ... are formed may be 1 ... 3, 4,5, 6 ... other than 2, and the second piles 5 ... are formed. The ratio of the wefts 13 may be 1, 2, 3, 5, 6, 7,..., 8, 9, 10,. Even in this case, the ratio of the wefts 13 that form the first piles 4 is higher than the ratio of the wefts 13 that form the second piles 5.

  In addition, about the warp yarn 12 ... in which the first pile 4 ... and the second pile 5 ... are not formed, the pile 14 ... is formed only on the surface of the first pile 4 ..., and only the second pile 5 ... is omitted. Good. Even with such a structure / form, the surface of the first piles 4... Has higher water absorption than the surface of the second piles 5.

  In addition, the warp yarns 11 forming the first pile 4 and the second pile 5 were alternately one in two, but one in three, two in three, one in four It may be changed as follows: three in four, one in five, two in five, three in five, four in five, and so on.

  Even in this case, the ratio of the warp yarns 11 ... on which the first piles 4 ... and the second piles 5 ... are formed is such that the surface of the first piles 4 ... is larger than the surface of the second piles 5 .... Even in such a structure / form, the number of the first piles 4 per unit area is larger than the number of the second piles 5 per unit area, and the surface of the first piles 4. The water absorption is higher than that of the surface 5.

  The warp yarns 11 ..., the warp yarns 12 ..., the weft yarns 13 ..., the first pile 4 ..., the second pile 5 ... are called bamboo fibers. Has been increased. The first pile 4 and the second pile 5 maintain air permeability, do not accumulate moisture, and maintain a soft cushioning property.

  It is waterproofed by the first laminated plastic layer 2 and can protect futons and mattresses from leakage. Since the first laminated plastic layer 2 is bonded directly to the first cloth 1 without any intervening therebetween, leakage from the seam of the first cloth 1 can be prevented.

(5) The material of the warps 11 ..., 12 ..., the wefts 13 ... Of the warps 11 ..., 12 ..., the wefts 13 ..., the warps that do not constitute or form the piles 4, 5 ..., 24 ..., 35 ..., 36 ... The material of 12.

  Of the warps 11 ..., 12 ..., wefts 13 ..., the material of the warps 11 ... constituting and forming the piles 4, 5 ..., 24 ..., 35 ..., 36 ... is made of cotton, silk, rayon, bamboo, etc. It may be made of a natural fiber and a material with high water absorption. Thereby, even if it uses the said synthetic fiber, water absorption is maintainable.

  Of both surfaces of the first fabric 1, one surface without the piles 4, 5, 24, 35, 36, and the lower surface of the first fabric 1 in FIGS. 4 and 5 are made of synthetic fibers. More warps 12 ... and wefts 13 ... are exposed. The other surface, the upper surface of the first cloth 1 shown in FIGS. 4 and 5 is covered with piles 4... 5, 24. , 24 ..., 35 ..., 36 ... more warps 11 made of natural fibers are exposed.

  Therefore, more yarns made of synthetic fibers are exposed than the yarns made of natural fibers on the surface to which the first laminated plastic layer 2 is adhered. Further, of the two surfaces of the first fabric 1, piles 4, 5, 24, 35, 36, 36 are formed on the surface where the first laminated plastic layer 2 is not adhered.

  The synthetic fiber warp yarns 12 and / or the weft yarns 13 have lower melting points, melting temperatures or softening temperatures than the natural fiber warp yarns 11 and are easily melted or softened. Thereby, in the production of the sheets, when the first laminated plastic layer 2 is stacked on one side of the first cloth 1 opposite to the piles 4, 5, 24, 35, 36, and pressed and heated, The one laminated plastic layer 2 is welded and adhered to the warp yarns 12 and / or the weft yarns 13 of the synthetic fiber, and the first laminated plastic layer 2 is firmly bonded to the first fabric 1 and is not easily separated. .

  The material of the synthetic fibers of the warp yarns 12 and / or the weft yarns 13 may be the same as the material of the first laminated plastic layers 2 and 32 and the second laminated plastic layer 33, or have a melting point, a melting temperature, and a softening temperature. Close, for example, the difference between these temperatures is 90 degrees Celsius or less, 80 degrees or less, 70 degrees or less, 60 degrees or less, 50 degrees or less, 40 degrees or less, 30 degrees or less, 20 degrees or less, 10 degrees or less, 5 degrees The following materials may be selected.

  Thereby, in the production of the sheet described later, the synthetic fiber, the first laminated plastic layers 2 and 32, and the second laminated plastic layer 33 are melted and softened to the same extent, and the first cloth 1, 31 or second cloth Adhesion between the cloth 21 and the first laminated plastic layers 2 and 32 and the second laminated plastic layer 33 is strengthened, and the adhesion is smoothly performed.

  The material of the warps 11 constituting the piles 4, 5, etc. includes the plant fibers, animal fibers and regenerated fibers, plant fibers such as hemp, animal fibers such as wool, semi-synthetic fibers including these fibers, etc. Anything that absorbs water can be used.

  The material of the warps 12 and / or the wefts 13 that do not constitute the piles 4, 5, etc. may be semi-synthetic fibers containing these synthetic fibers in addition to the synthetic fibers, and are meltable or soft when heated. Anything is fine.

(6) How to use the sheet (first embodiment) The above sheet is used alone by being laid on a futon or a mattress. In the rectangular sheet, the longitudinal direction of the sheet may be arranged in the longitudinal direction along the longitudinal direction of the futon or the like, and the longitudinal direction of the sheet is arranged in the lateral direction intersecting with the longitudinal direction of the futon or the like. Also good. Since the first laminated plastic layer 2 is square, there is no difference in leakage prevention in either direction.

  At this time, the first pile 4 surface and the second pile 5 surface are the upper surface, and the first laminated plastic layer 2 surface is the lower surface. Thereby, even if the first laminated plastic layer 2 is damaged due to washing or other long-term use, the water before leaking from the damaged portion can be sufficiently absorbed, and leakage is prevented, and the first pile 4. The two piles 5 ... keep breathability and keep moisture away.

  When the sheets are used, the first laminated plastic layer 2 surface may be the upper surface, and the first pile 4... Surface and the second pile 5. As a result, even if the first laminated plastic layer 2 is damaged due to washing or other long-term use, the water after leaking from the damaged portion can be sufficiently absorbed, and leakage is prevented, and the first pile 4. The second pile 5 keeps air permeability and does not accumulate moisture.

  Note that at least two sheets may be stacked, and the two sheets are used with the first pile 4 surface and the second pile 5 surface facing each other. As a result, even if moisture leaks from the damaged portion of the first laminated plastic layer 2, not only the first pile 4 of the upper layer but also the first pile 4 of the first fabric 1 of the lower layer, Moisture can be sufficiently absorbed, leakage is prevented, and the first pile 4... And the second pile 5.

  Further, at least two sheets are stacked, and the two sheets are used with the surfaces on the first laminated plastic layer 2 side facing each other. As a result, even if moisture leaks from the damaged portion of the first laminated plastic layer 2, it can be waterproofed by the first laminated plastic layer 2 of the lower first cloth 1, preventing leakage, and the first pile. The air permeability is maintained by 4 ... and the second pile 5 ..., and moisture does not accumulate.

  On the opposite side of the second fabric 21 from the first laminated plastic layer 2, third piles 24 are formed. The third piles 24 are the same size, shape and weave as the first piles 4. This second fabric 21 is woven in the same weaving manner with the same warps 11 ..., warps 12 ..., wefts 13 ... as the first fabric 1, and the third piles 24 ... are formed on the warps 11 ... A pile is not formed on the wefts 13... But they are ground yarns (ground warp yarns).

  The warp yarns 11 forming the third piles 24 of the second fabric 21 are natural fibers with high water absorption, such as cotton and linen, and the other warp yarns 12 and weft yarns 13 are synthetic fibers such as polyester (chemical Fiber). The proportion of natural fibers is 10% to 40%, 20%, and the proportion of synthetic fibers (chemical fibers) is 60 to 90%, for example 80%.

  Therefore, on the flat surface without the third pile 24... Laminated on the first laminated plastic layer 2 of the second fabric 21, a lot of synthetic fibers (chemical fibers) such as polyester are exposed, and cotton is less exposed. Become. Thereby, the 1st laminated plastic layer 2 joins well, a joining degree improves, and an adhesiveness and a lamination degree improve.

  The said 1st cloth 1, the 1st laminated plastic layer 2, and the 2nd cloth 21 are the same shape same size, are laminated | stacked on three layers, and each periphery is substantially corresponded. Thereby, the 1st cloth 1 and the 2nd cloth 21 are stuck and laminated on the both surfaces over the entire surface of the first laminated plastic layer 2, and the entire first laminated plastic layer 2 is completely protected, so that it can be used for washing and long use. It becomes difficult to break.

  The first laminated plastic layer 2 may be smaller than the first cloth 1 and the second cloth 21 as in the first embodiment. In this case, the first cloth 1 without the first laminated plastic layer 2 (the plastic non-regions 3 and 3) and the second cloth 21 are stitched together. In this case, the plastic non-regions 3 and 3 may also be formed on the second cloth 21.

  As with the first cloth 1, the second cloth 21 may be formed with two types of piles of first piles 4 ... and second piles 5 .... In this case, the first laminated plastic layer 2 may be bonded and laminated on the opposite side of only the third pile 24... That is the same as the first pile 4.

  The second cloth 21 may be completely replaced by the first cloth 1 provided with the first piles 4... And the second piles 5. The second cloth 21 provided may be completely replaced.

  The second cloth 21 may be made of bamboo fiber, like the first cloth 1, and may be subjected to graft polymerization processing on the bamboo fiber cloth to enhance the antibacterial / deodorant effect. Conversely, the first fabric 1 may be composed of natural fibers such as cotton and synthetic fibers (chemical fibers) such as polyester, like the second fabric 21. The third piles 24 may be the same shape, the same size, and the same weave as the second piles 5 instead of the first piles 4.

  The second cloth 21 is bonded and adhered to the first laminated plastic layer 2. In this case, the rolling roller or the like is used, and the first cloth 1 is bonded and adhered to the first laminated plastic layer 2 in the same manner. Executed. In addition, the 1st cloth 1, the 1st laminated plastic layer 2, and the 2nd cloth 21 may be laminated | stacked simultaneously, and it may be jointly adhere | attached laminated | stacked simultaneously using a rolling roller.

  The second cloth 21 may be replaced with the first cloth 1 or the piles 5 may be replaced with the piles 4. The piles 24 ... may be completely replaced by the piles 4 ... and / or the piles 5 ....

(8) Sheet (third embodiment)
FIG. 7 shows a side view of a third embodiment of the sheet. In the present embodiment, the first laminated plastic layer 32 is bonded and laminated on one side of the first cloth 31 and the lower side of FIG. 7, and the other side of the first cloth 31, the upper side of FIG. 7. A second laminated plastic layer 33 is bonded and adhered to a central portion of a part of the surface.

  The first laminated plastic layer 32 and / or the second laminated plastic layer 33 is the same as the first laminated plastic layer 2 described above. Outside the both edges of the first cloth 31 in the longitudinal direction of the second laminated plastic layer 33, there is no second laminated plastic layer 33 and the surface of the first cloth 31 is exposed. It has become.

  Fourth piles 35, 36,... Are formed on the plastic non-regions 38, 38, that is, the remaining part of the other side of the first cloth 31 and on both sides of the second laminated plastic layer 33. . The fourth piles 35 ... and / or 36 ... are the same as the first piles 4, ..., the second piles 5, ... and / or the third piles 24 ....

  The warps 11 constituting the fourth piles 35, 36 are made of the natural fibers, and the other warps 12 and / or the wefts 13 are made of the synthetic fibers. Natural fiber warp yarns 11 are not used in the portion of the first cloth 31 that is in close contact with the second laminated plastic layer 33, but are woven only with synthetic fiber warp yarns 12 and / or weft yarns 13. Therefore, the first laminated plastic layer 32 and the second laminated plastic layer 33 are firmly adhered to both the front and back surfaces of the first cloth 31 and are difficult to peel off.

  In the present embodiment, the laminated plastic layer has two layers, and the waterproofness is further increased. Since the fourth piles 35, 36,... Are formed on both sides of the second laminated plastic layer 33, the water absorption is maintained.

  In the center of the second laminated plastic layer 33, one or more rows, plastic non-regions 38 and 38, and fourth piles 35, 36, ... may be formed. Plastic non-regions 38 and 38 and fourth piles 35... 36 may be formed on both surfaces of the first cloth 31.
