Description

  The present invention relates to a fiber-forming layer material separated from a tile carpet, or the fiber-forming layer material, or a long or block-like sheet material including at least one of the fiber-forming layer material and the carpet or the tile carpet, and a method of using the same. It is about.

  Ten years have passed since tile carpets were widely used, and the time has come for renewal. On the other hand, the disposal of waste has become difficult year by year, and in particular, vinyl chloride resin-based products are accompanied by the problem of dioxins, and the disposal is even more difficult. It has become to.

  In the US, etc., after cleaning, the fiber-forming layer material on the surface is dyed again, patterned, and reused. However, it is difficult to sufficiently remove the soiled fiber-forming layer material, and the dyeing color is inevitably Actually, it is limited to dark colors.

  As a technique for reusing tile carpets, there are techniques described in Patent Documents 1 and 2. In these techniques, a surface-decorating resin layer is formed on the front surface or the back surface of the waste material obtained by substantially cutting and removing the fiber-forming layer material. The reason why the fiber-forming layer material is substantially cut and removed is that when the fiber-forming layer material is present, an adhesive or a pressure-sensitive adhesive cannot be applied to the surface. Therefore, in these techniques, it was necessary to substantially cut off the fiber forming layer material. However, as a result, there is a problem that a large amount of fiber waste of the fiber forming layer material is generated and becomes industrial waste, and a mowing process of the fiber forming layer material is required, which causes an increase in cost.

  In addition, a method of finely pulverizing the recovered tile carpet described in Patent Documents 3 to 5 and separating the fiber-forming layer material and the vinyl chloride backing layer by a specific gravity separation method or the like is generally performed. Crushing tile carpets requires a lot of energy, and noise during pulverization is large.

  Furthermore, Patent Document 6 proposes to make a tile carpet using a backing layer that can be easily pulverized by freezing to minus 30 ° C. or lower. However, the soft vinyl chloride already on the market is used as the backing layer. Since it is necessary to make the freezing temperature extremely low for application to the tile carpet, it has not been put into practical use.

  Further, Patent Document 7 discloses a method of scraping a vinyl chloride backing layer of a tile carpet by a planar, or Patent Document 8 discloses a method of scraping a vinyl chloride layer with a cylindrical rotary tool unit having a large number of cutting edges. Patent Document 9 describes a method of separating a boundary between a fiber forming layer material of a tile carpet and a vinyl chloride backing layer in a planar direction with a scraper knife, both of which aim to reuse the vinyl chloride backing layer. It is not intended to reuse the fiber-forming layer material of the carpet.

  Further, in Patent Document 10, in a tile carpet in which the fiber forming layer material and the vinyl chloride backing layer are bonded with a hot melt adhesive, the hot melt adhesive is heated and melted to form both layers. Although a method of peeling is proposed, it is not intended to reuse the fiber-forming layer material.

Patent Document 11 describes that a decorative layer is provided on the surface of a vinyl chloride backing layer of a tile carpet and used as a floor material as a recycled tile. However, a fiber-forming layer material separated from a carpet or tile carpet is described. There is no disclosure regarding technology to be reused for a specific application.

  The present invention provides a fiber-forming layer material that is efficiently separated and recovered from a tile carpet composed of a fiber-forming layer material and a vinyl chloride backing layer, without requiring a great deal of energy, generation of noise and dust, and the like. The purpose is to provide usage.

  Furthermore, another object of the present invention is to provide the fiber-forming layer material after separating the fiber-forming layer material and the vinyl chloride backing layer constituting each from the used or lost tile carpet. The present invention provides a long or block sheet material that can be effectively reused.

  In order to achieve the above object, the present invention employs a basic technical configuration as shown below.

That is, as a first aspect of the present invention, a fiber having a predetermined unit surface area and a pile layer in which a plurality of fibers are planted on one surface of the base fabric layer and the base fabric layer is formed. The backing layer is peeled and removed from a tile carpet composed of an aggregate layer and a backing layer containing a synthetic resin formed on the surface of the base fabric layer opposite to the surface on which the fiber assembly layer is formed. The base fabric layer is formed on the surface of the base fabric layer opposite to the surface on which the fiber assembly layer is formed. And a fiber bonding portion made of the synthetic resin layer having a thin and uniform or non-uniform thickness for bonding a portion of the fibers constituting the fiber assembly layer engaged with the base fabric layer. Using at least two pieces of the fiber-forming layer material, The layered material is a block-shaped sheet material characterized by being joined without interposing a reinforcing sheet or intervening reinforcing sheets so that the fiber bonding portions containing the synthetic resin face each other, As a second aspect of the present invention, a fiber assembly having a predetermined unit surface area, and a base fabric layer and a pile layer in which a plurality of fibers are planted on one surface of the base fabric layer are formed. The backing layer is peeled and removed from a tile carpet comprising a layer and a backing layer containing a synthetic resin formed on the surface of the base fabric layer opposite to the surface on which the fiber assembly layer is formed. And the surface of the base fabric layer opposite to the surface on which the fiber assembly layer is formed in the fiber forming layer material. Constructs the fiber assembly layer that engages with the base fabric layer A plurality of fiber-forming layer materials on which a fiber-bonding portion made of a synthetic resin layer having a thin and uniform or non-uniform thickness is bonded to a part of the fibers to be disposed and fixed on the floor. It is a sheet material formed into a long shape used as a raw material for a block-shaped sheet or an industrial material sheet, which is formed by two-dimensionally adjoining each other.

  The method for obtaining the fiber-forming layer material as shown in the first problem in the present invention is also shown in some of the above-mentioned patent documents, but in the present invention, the fiber-forming layer material is used. The method for obtaining the fiber-forming layer material is not particularly specified, and the following methods, including known techniques, may be used. The tile carpet that has been used or has lost its market value is reused as it is as a new industrial material.

Therefore, as a first specific example of the method for forming the fiber-forming layer material in the present invention,
(1) A tile carpet composed of a fiber forming layer material including a fiber assembly layer and a vinyl chloride backing layer is heated to 120 ° C. to 180 ° C., and as shown in FIG. 2, the fiber forming layer material 2 and vinyl chloride The fiber-forming layer material 2 is separated and recovered from the tile carpet 1 by mechanically holding and fixing the end portion of the backing layer 3 by appropriate means 4 and displacing the holding and fixing portions so as to be separated from each other in opposite directions. It is a method to do.

  A peeling treatment surface is formed on at least a part of the synthetic resin layer of the synthetic resin layer included in the fiber bonding portion 64 of the fiber forming layer material 2 formed by such a method.

  (2) A second method of separating the fiber forming layer material and the vinyl chloride backing layer from each other from the tile carpet configured to include the fiber forming layer material and the vinyl chloride backing layer according to the present invention. As a specific example, as shown in FIG. 17, a scraper blade is brought into contact with the boundary portion between the fiber forming layer material and the vinyl chloride backing layer of the tile carpet that has been heated to a predetermined temperature in advance, and the chloride It is also possible to use a method of scraping off the vinyl backing layer, or a method of scraping only the vinyl chloride backing layer using a planer (鉋) as shown in FIG. 18, and further, as shown in FIG. Similarly, the band knife splitter that moves endlessly is brought into contact with the boundary between the fiber forming layer material of the tile carpet and the vinyl chloride backing layer, and an appropriate portion of the boundary is cut. It is also possible to use a method for separating the two by that.

  By using the separation and recovery method as described above, the fiber-forming layer material 2 obtained from the tile carpet has almost no deviation or deformation with respect to the original dimensions. When forming the long sheet material by arranging the two fiber-forming layer materials 2 two-dimensionally, it is convenient because the dimensions are easily adjusted.

  (3) Alternatively, as a third specific example of the present invention, a method of dissolving or melting the adhesive layer formed between the fiber forming layer material and the vinyl chloride backing layer to separate them can be used. is there.

  (4) Further, the inventors of the present invention pass the heated carpet or tile carpet through a roll (friction roll) having a rotational speed difference as a method for efficiently separating and recovering the vinyl chloride backing layer from the carpet or tile carpet. Has already proposed a method for separating and recovering a vinyl chloride backing layer (Japanese Patent Application No. 2002-320421 (Japanese Patent Application Laid-Open No. 2004-168023)), and it goes without saying that such a method can also be used in the present invention.

  (5) In the present invention, as still another example of the method for forming the fiber-forming layer material 2, for example, Japanese Patent Application No. 2004-61910 filed on March 5, 2004 by the applicant of the present patent application. A carpet or tile carpet composed of a fiber assembly layer having a predetermined thickness and a backing layer having a predetermined thickness formed on one side of the fiber assembly layer as disclosed in Alternatively, a method of separating at least a part of the backing layer from the fiber assembly layer or a part of the backing layer by applying a pressing shear force to the outer surface of the backing layer to the backing layer of the ear burr scrap As a specific example, the rotation speed difference between the rotation speeds of the pair of rolls is 1.2 to 5 times. The gap between the pair of rolls is set to be equal to or less than the thickness of the backing layer constituting the carpet, tile carpet or ear burr scrap (hereinafter simply referred to as carpet group), and the tile carpet group heated to a temperature of 90 to 190 ° C. The pair of rolls is supplied so that the backing layer is in contact with the roll having the higher rotation speed and is passed through the gap between the pair of rolls, whereby the fiber aggregate layer and the backing layer of the tile carpet group Causing a gap between layers in the boundary surface or in the backing layer, and causing at least a part of the backing layer to peel from the fiber assembly layer or a part of the backing layer bonded to the fiber assembly layer. It is also possible to use a method constructed in

  (6) Alternatively, as a sixth specific example of the present invention, in a state where the carpet is heated while being kept flat, the backing layer is brought into close contact with the conveying means, and is moved. A carpet peeling method in which the moving direction of the backing layer is sharply bent, and then the traveling direction of the fiber forming layer material is set to a direction different from the traveling direction of the backing layer.

  A slip-peeling treatment surface is formed on at least a part of the fiber bonding portion 64 of the fiber-forming layer material 2 formed using the carpet group separation and recovery method.

  Since the fiber-forming layer material separated and recovered by the above method is deformed in dimensions due to the friction in the peeling process, as described later, prior to processing into a block-like or long sheet material in the present invention, as appropriate, It is necessary to trim to the dimensions of

  That is, in the present invention, the above-described conventionally known fiber forming layer material and the vinyl chloride backing layer are separated from each other, and the carpet is more efficiently different from the above method proposed by the present inventors. Alternatively, a method in which the fiber forming layer material and the vinyl chloride backing layer are separated from each other from the tile carpet is used.

Furthermore, in the present invention, the tile carpet itself that has been used or whose market value has been lost is effectively reused, and at the same time, the fiber-forming layer material and the vinyl chloride backing layer constituting each are separated. The present invention provides a fiber-forming layer material and an elongated or block-like sheet material that enables effective reuse of the fiber-forming layer material later. In the present invention, the fiber-forming layer material is elongated from the fiber-forming layer material. Alternatively, a regenerated carpet having a loop layer on the back surface or a carpet formed by forming a block-shaped sheet material and bonding the long or block-shaped sheet material and an unused carpet raw material so that the mutual loop layers come outside Is obtained to obtain a regenerated tile carpet.

  Further, when the long or block sheet material and the unused carpet raw fabric are bonded together with the loop layers coming to the outside, a double-sided pressure-sensitive adhesive tape is used as a bonding material. Alternatively, when the recycled tile carpet has been used, and when it is necessary to separate and recover the backing layer made of the front surface carpet layer and the fiber forming layer material on the back surface, the recycled carpet or the recycled tile carpet is heated with hot water. Peeling and separation can be easily performed.

  The present invention has the following effects.

  (1) A simple operation of heating and gripping a tile carpet with a pair of gripping means from a tile carpet waste that has conventionally been disposed of in a managed industrial waste disposal site or incinerated. In the process, the fiber forming layer material and the vinyl chloride backing layer can be separated.

  (2) In addition, the fiber-forming layer material obtained by the present invention, and the fiber-forming layer material may be combined with a tile carpet that has been used or unused but has no opportunity for use and lost its market value. The use of long or block sheet materials that can be used will ensure new uses for tile carpet waste, which has been a problem for disposal in the past. At the same time, it has the effect of greatly contributing to environmental conservation.

  Furthermore, in the present invention, the fiber-forming layer material obtained by the present invention, or a tile carpet and a carpet raw fabric that have been used or unused but have no opportunity for use and lost market value are appropriately combined. Thus, it can be used again as a recycled carpet or recycled tile carpet.

  (3) Furthermore, in the present invention, by using a specific separation and recovery method, it is possible to obtain a fiber-forming layer material with less dimensional deformation. There is no need for the operation of trimming to the dimensions, and the sheet material can be formed by adjoining each other as they are.

  (4) Further, in the present invention, the fiber-forming layer material obtained by the present invention, and tile carpets and carpet raw fabrics that have been used or unused but have no opportunity for use and lost market value. Are used again as a recycled carpet or recycled tile carpet by adopting a double-sided adhesive tape that is easy to peel and separate, and then the recycled carpet or recycled tile carpet is used again, and the carpet layer on the surface and the back surface When it is necessary to separate and recover the backing layer made of the fiber-forming layer material, it is possible to easily perform separation separation by heating the recycled carpet or recycled tile carpet with hot water. Tile carpets will always be reused as useful resources.

  Hereinafter, the present invention will be described in detail.

  The tile carpet in the present invention refers to a floor finish material having a two-layer structure of a fiber-forming layer material (fiber layer) and a vinyl chloride backing layer (backing layer), and does not include a bitumen backing. .

  In the present invention, the tile carpet 1 is heated within a temperature range of 120 ° C. to 180 ° C. in order to separate the fiber forming layer material (fiber layer) 2 and the vinyl chloride backing layer 3 from the tile carpet 1 individually. There is a need to. Preferably, the heating temperature range is 130 ° C. to 180 ° C. for nylon and 120 ° C. to 160 ° C. for polypropylene.

  That is, in the case of nylon, if the temperature range is less than 120 ° C., the fiber forming layer material (fiber layer) and the vinyl chloride backing layer are not smoothly peeled, and if it exceeds 180 ° C., the vinyl chloride backing is exceeded. Decomposition may begin in the layers, making separation more difficult.

  On the other hand, in the case of polypropylene, if the temperature range is less than 120 ° C., the fiber forming layer material (fiber layer) and the vinyl chloride backing layer are not smoothly separated, and if it exceeds 180 ° C., Decomposition may begin in the vinyl backing layer, making separation more difficult and melting polypropylene fibers, making them unusable.

  In the present invention, the heating temperature refers to a value obtained by measuring the surface temperature of the vinyl chloride backing layer of the tile carpet with a non-contact thermometer immediately after the tile carpet is taken out of the heating furnace.

  The present invention is preferably used when the tile carpet fiber has a low tensile strength when heated, such as polypropylene, and a low adhesive strength with the vinyl chloride backing layer.

  As a method of heating the tile carpet, a method of blowing hot air to the tile carpet 1, a method of passing the tile carpet 1 through the heating furnace 14 as shown in FIG. 2, a method of passing an infrared heater, and the tile carpet Examples include a method of passing 1 over a hot plate, a method using dielectric heating, a method using ultrasonic heating, and the like.

  In order to separate the fiber-forming layer material 2 and the vinyl chloride backing layer 3 from the tile carpet 1 and recover the fiber-forming layer material 2, the fiber-forming layer material 2 and vinyl chloride of the heated tile carpet 1 are collected. After the end portions of the backing layer 3 are individually and securely gripped by appropriate gripping and fixing members 4, the gripping and fixing members are arranged in directions in which the gripping and fixing portions are separated from each other, for example, in opposite directions. By moving and displacing 4, the structure is destroyed at the interface between the fiber forming layer material and the vinyl chloride backing layer in the tile carpet 1, and peeling occurs.

  As an extremely simple method, as illustrated in FIG. 1, there is a method of sandwiching a pair of pliers and pulling the pliers in directions opposite to each other. One of the gripping and fixing parts 4 having a protruding portion is gripped and fixed on the fiber-forming layer material, and on the other hand, the vinyl chloride backing layer is gripped and fixed, and the pair of carpet gripping and fixing parts 4 are used with appropriate driving means. Thus, a method is generally employed in which the layers are moved in directions opposite to each other, the structure is destroyed at the interface between the fiber forming layer material and the vinyl chloride backing layer, and both layers are separated.

  In principle, the gripping fixture used in the present invention can use pliers, but the present invention is not limited to this, and any mechanical gripping means may be used. Any gripping and fixing means can be used.

  The separated fiber-forming layer material has, on the back surface thereof, a fiber bonding portion in which a backing layer made of a synthetic resin such as vinyl chloride remains and adheres, and at least of the fiber bonding portion A peel-off treatment surface is formed on a part of the synthetic resin.

  The fiber-bonding portion 64 provided in the fiber-forming layer material 2 in the present invention has a part of the synthetic resin component mainly composed of vinyl chloride, which has previously formed a backing layer of the tile carpet, as the base. Since it is formed to remain on the cloth layer surface, its thickness is extremely thinner than the thickness of the backing layer, and the thickness itself is substantially irregular, In addition, it has a function of fixing a part of the fibers of the pile yarn constituting the fiber assembly layer 65 engaged with the base fabric layer to the base fabric layer.

  In addition, after the fiber-forming layer material is formed, the surface of the fiber-binding part can be flattened by passing the fiber-bonding part between heated calender rollers, for example.

  Examples of specific steps of the above method will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view showing the principle of a method for separating and collecting the fiber forming layer material 2 from the tile carpet 1 by the separation method of the present invention.

  The tile carpet 1 is heated to 120 ° C. to 180 ° C., and the ends of the fiber-forming layer material 2 and the vinyl chloride backing layer 3 of the heated tile carpet 1-1 are appropriately paired with gripping and fixing members such as pliers. The fiber-forming layer material 2 can be separated and recovered by fixing it at 4 and pulling it away in opposite directions.

  FIG. 2 is a cross-sectional view showing an example of a process for separating and collecting the fiber-forming layer material and the vinyl chloride backing layer from the tile carpet 1 of the present invention.

  The collected tile carpet 1 rides on the conveyor 26, passes through the heating furnace 14, becomes a heated tile carpet 1-1, and rides on the conveyor 26 and comes out of the heating furnace 14. At this time, the end portion 23 of the fiber-forming layer material 2 is gripped by the gripping and fixing means 4-1, and the end portion 23 'of the vinyl chloride backing layer is gripped by the gripping and fixing means 4-2. The fiber forming layer material 2 and the vinyl chloride backing layer 3 are separated by pulling in the X2 method), and conveyed separately to the conveyor 26-4 and the conveyor 26-3, respectively.

  EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to the examples.

Example 1
The tile carpet 1 (total thickness 6.5 mm, vinyl chloride backing layer thickness 3.0 mm) is placed in a heating furnace 14 at 200 ° C. using a tile carpet separation and recovery process as shown in FIG. After 5 minutes, the surface temperature of the vinyl chloride backing layer 3 of the tile carpet 1 is heated to 140 ° C., and the corners of the vinyl chloride backing layer 3 and the fiber-forming layer material 2 are mechanically fixed to each other in the opposite direction. The fiber forming layer material 2 and the vinyl chloride backing layer 3 could be separated and recovered by pulling them apart. The weight ratio of the fiber-forming layer material 2 and the vinyl chloride backing layer 3 of the tile carpet 1 before separation and recovery was about 13 to 87. As a result of separation into two layers through this process, the vinyl chloride backing layer 3 The fiber-forming layer material 2 partially adhering in powder form (30% by weight) and the pure vinyl chloride backing layer 3 (70% by weight) could be separated.

Comparative Example 1

The sample was processed under the same conditions as in Example 1 except that the sample was heated to a high temperature. As a result, the fiber forming layer material 2 and the vinyl chloride backing layer 3 were partially adhered to each other, and could not be separated smoothly and only partially.

Comparative Example 2

As a result, it was possible to separate into the vinyl chloride backing layer 3 and the fiber-forming layer material 2 to which a part of the vinyl chloride backing layer 3 was adhered, but the polypropylene carpet melted because the surface temperature of the tile carpet was too high. The fiber forming layer material 2 could not be reused.

  Next, as an aspect for solving another problem in the present invention, it is possible to effectively reuse a used tile carpet itself or to lose the market value, and at the same time, a fiber forming layer material constituting each of them.

A method for forming the material 100 and its configuration will be described in detail.

  That is, as a specific example of the long sheet material 100 formed into a long shape according to the present invention, as shown in FIG. 8C, the fiber-forming layer material 2 or various block-shaped sheet materials described above are used. The sheet material 100 is formed in a long shape, characterized in that a plurality of 200 are two-dimensionally arranged adjacent to each other.

  Furthermore, if the sheet material 100 configured in a long shape according to the present invention is described in more detail, a unit sheet material composed of a unitary fiber-forming layer material 2 having a predetermined length and width as a basis thereof. Alternatively, as shown in FIGS. 8A to 8C, the various block-shaped sheet materials 200 described above are two-dimensionally arranged adjacent to each other, and the edges 11 that are in contact with each other are appropriately bonded. When the plurality of unit sheet materials 1 and 2 are two-dimensionally arranged adjacent to each other and bonded to each other, at least the unit sheet material 2 or the block-shaped sheet material 200 adjacent to each other are used. A part is overlapped and an appropriate adhesive is used for the portion 10 where the plurality of unit sheet materials 2 or the block sheet material 200 are overlapped and overlapped with each other. Luke, whether to perform heat-sealing, and may be those treated immobilized by suturing processed using an appropriate suture 12.

Furthermore, although not illustrated, it is also preferable to bond an appropriate reinforcing sheet 7 to the back side of the sheet material 100 in the long sheet material 100 shown in FIG.
That is, the plurality of block-shaped sheet materials 200 may be two-dimensionally adjacent to each other via the reinforcing sheet 7.

  Specific examples thereof will be described in detail below.

  First, as a first configuration example of the long sheet material 100 in the present invention, as shown in FIG. 5, a plurality of the fiber forming layer materials 2 which are unit sheet materials having a predetermined length and width are provided. These are arranged in a matrix form and connected to each other, or connected to an appropriate reinforcing sheet 7 without connection using an appropriate adhesive 8 as necessary to form a long sheet material 100. .

  That is, in the specific example of FIG. 5, all the fiber bonding portions 64 of the plurality of fiber forming layer materials 2 are arranged so as to face the reinforcing sheet 7 and bonded and fixed.

  Furthermore, in the present invention, as another embodiment, as shown in FIG. 6 (A), for example, the two fiber forming layer materials 2 are opposed to each other, and the fiber coupling portions 64 are opposed to each other. As shown in FIG. 6B, one tile carpet 1 and one fiber forming layer material 2 are composed of a backing layer 3 containing a synthetic resin and fiber bonding portions 64 containing the synthetic resin. May be the long sheet material 100 joined to each other with the reinforcing sheet 7 interposed therebetween.

  That is, the long sheet material 100 in the present invention is formed in a long shape by forming a plurality of block shapes 200 as the unit sheet material, two-dimensionally adjacent to each other. It may be a structure of the sheet 100.

  In addition, since the block-like sheet material 200 according to the present invention shown in either FIG. 6A or FIG. 6B has a fiber assembly layer 65 including loop piles on both sides, it is arranged. This can be used as a new type of tile carpet, and at the same time, if the embodiment shown in FIG. 6A or 6B is embodied with respect to the carpet 9, it can be used as a new carpet 9 as a matter of course. It is.

  On the other hand, the long sheet material 100 or the block-shaped sheet material 200 in the present invention includes, for example, a protective sheet for waterproofing and waterproofing, a floor finish sheet, a decorative sheet, an outdoor tile carpet, and a curing sheet for a roof garden. Used for etc.

  Further, the reinforcing sheet 7 used in the present invention is preferably waterproof, and the reinforcing sheet is, for example, a woven or knitted fabric, a nonwoven fabric, a cold koji, or an appropriate resin processing applied to these fabrics. It is preferable that it is made of one selected from a fabric, a plastic film-like sheet or a plastic porous sheet.

  If the above-described specific example is described in more detail, as shown in FIG. 9A and FIG. 9B, a plurality of the fiber-forming layer materials 2 are made up of fiber assemblies of the respective fiber-forming layer materials 2. The first and second layers are formed by two-dimensionally adjoining each other so that the layer 65 forms the same surface, or by overlapping and overlapping at least a part of the fiber forming layer material 2 adjacent to each other. The long sheet material layers 120 and 130 are bonded to each other so that the fiber bonding portions 64 of the fiber forming layer materials 2 of the long sheet material layers 120 and 130 face each other. In forming the sheet material, adjacent boundary lines or adjacent overlapping overlapping lines formed between the plurality of mutually adjacent block-shaped sheet materials in the first sheet material layer 120, and the second Plural in the sheet material layer 130 It is also possible to the corresponding block-like sheet material adjacent the boundary line is formed between or adjacent overlapping overlapping lines adjacent to each other is constructed as being arranged offset to one another.

  In this embodiment, one of the first and second long sheet material layers 120 and 130 may be composed of only the plurality of first tile carpets 1 can be used.

  That is, the conventional tile carpet 1 is provided with a backing layer that is a backing layer 3 made of vinyl chloride. When the tile carpet with the backing layer made of vinyl chloride is used in a home, a double-sided adhesive tape is used. However, the plasticizer in vinyl chloride is bleed (the bleed is a plasticizer compounded for softening vinyl chloride that migrates to other materials that are leached and in contact with rubber, etc. However, it is a phenomenon that occurs) and the adhesive tape becomes muddy and sticky. Therefore, in the present invention, if there is a fiber assembly layer including a loop pile on the back side of the tile carpet, a hook-and-loop fastener can be used at the time of enforcement. The state of use will be promoted.

  Further, in this specific example, as shown in FIG. 9C, the first long sheet material layer 120 is composed of, for example, the tile carpet-like fiber-forming layer material 2 only. The second long sheet material layer 130 may be composed of, for example, the tile carpet 1 alone, and in this case, the first long sheet material layer The fiber aggregate layer 65 of the tile carpet 1 constituting the second elongated sheet material layer 130 faces the fiber bonding portion 64 side of the tile carpet-like fiber forming layer material 2 constituting 120. It may be arranged and configured as such.

  On the other hand, another specific example of the long sheet material 100 in the present invention will be described in detail with reference to FIG.

  That is, as shown in FIG. 11, a carpet 9 that has been used or has lost its market value is prepared, and a plurality of fiber-forming layer materials 2 are placed on the backing layer 3 side that is the vinyl chloride backing layer of the carpet 9. The backing layer 3 and the fiber bonding portion 64 are arranged so as to face each other, and have a configuration in which both are bonded and fixed via an appropriate adhesive 8 with or without using an appropriate reinforcing sheet 7 therebetween. It is.

  In this specific example, it is possible to use the long sheet material 100 as it is for an appropriate application. However, in some cases, the sheet material is cut into a tile carpet shape, and fiber aggregates are gathered on both sides. A tile carpet having a body layer is also possible.

  Further, in the present invention, the sheet material 100 formed in the above-described long shape and the wide-width long-shaped carpet raw fabric 9 or the carpet 9 subjected to the dyeing finish are interposed between the reinforcing sheet 7. A tile carpet extracted from a multilayer sheet laminated so that the backing fabric or fiber bonding portion of the long sheet material is opposed to the base fabric surface of the carpet original fabric or dyed finish without intervening May be present.

  In this specific example, the carpet 9 may include a new carpet that has already lost its market value, or a used carpet 9 may be used.

  Similarly, the tile carpet is also a pre-use tile carpet that has already lost its market value or can be used, and industrial waste can be recycled, which is effective in reducing waste.

  Further, in the present invention, in the sheet material 100 formed into a long shape, the fiber forming layer material 2 or the block-shaped sheet material 200 is two-dimensionally arranged adjacent to each other. As shown in FIG. 8D, the arrangement direction P of the pile yarns 62 constituting the fiber assembly layer 65 in each of the fiber forming layer material 2 or the block-shaped sheet material 200 is any. May be arranged so as to be the same, or, as shown in FIG. 8E, a plurality of the fiber forming layer materials are two-dimensionally arranged adjacent to each other. When the first and second long sheet materials are laminated to form a laminated long sheet material, the first long sheet material is configured. The fiber assembly layer in the fiber forming layer material is formed. The arrangement direction of pile yarns to be arranged is different from the arrangement direction of pile yarns constituting the fiber assembly layer in the fiber forming layer material constituting the sheet material formed in the second elongated shape. It may be arranged in the same way.

  In the former configuration in this specific example, the long sheet material 100 exhibits directionality in its flexibility, and in particular performs an operation of pulling out the loop pile yarn from the long sheet material 100. In the latter configuration, there is an advantage that the strength of the long sheet material 100 is improved.

  The sheet material 100 or the fiber-forming layer material 2 or the block-shaped sheet material 200 according to the present invention described above can be used as various industrial material sheets. It can be used for one selected from a base sheet including a protection sheet for a waterworks, a floor finish sheet, a wall or ceiling material, an outdoor (for foot) tile carpet, and a roof garden curing sheet.

  Further, when the sheet material 100 or the fiber-forming layer material 2 or the block-shaped sheet material 200 according to the present invention is used as a floor finish sheet, a loop pile in the fiber-forming layer material or the sheet material is used. Since the fiber assembly layer 65 that constitutes can function as an engaging member that engages with a large number of hook-shaped portions that constitute the hook-and-loop fastener, for example, a large number of hooks that constitute the hook-and-loop fastener on the floor surface The tile carpet 1 or the fiber forming layer material 2 having the fiber assembly layer 65 constituting the loop pile is faced down and brought into contact with the hook-and-loop fastener by bonding and fixing so that the surface portion forms a surface. By doing so, the tile carpet 1 or the fiber forming layer material 2 can be fixed as a floor finish.

  Alternatively, the plurality of hook-shaped portions of the hook-and-loop fastener having a plurality of hook-shaped portions in the fiber-forming layer material 2 having the fiber assembly layer 65 that previously configures the loop pile constitutes the fiber assembly that configures the loop pile. When the fiber forming layer material 2 or the sheet material 200 is placed on a predetermined floor surface as a floor finish, the release paper covering the adhesive surface of the hook-and-loop fastener is removed. The floor finishing treatment can be performed by adhering the adhesive material to the floor surface.

  Further, as shown in FIG. 16, at least a part of the fiber-forming layer material 2 and the long sheet material 100 or the block-shaped sheet material 200 in the present invention is provided with a vent hole or a water hole 500. By adopting such a configuration, for example, as an OA room floor material, it can be used as a breathable floor material when an air conditioner function is provided at the lower part of the floor. At the same time, it can be used for applications that require water permeability and air permeability in agricultural materials and some industrial materials.

  In addition, the collected tile carpet is not exposed to the outside of the tile carpet or floor finish with a wide non-woven fabric or plastic sheet using heat or an adhesive, and the fiber aggregate layer of the tile carpet is outside. Can be used as a tile carpet having a loop layer on the lower surface or a floor finishing material.

  Hereinafter, a specific example of the method for producing the block-shaped sheet material 200 according to the present invention will be described in detail.

  That is, as a manufacturing method of the block-shaped sheet material in the present invention, basically, in the combination of the fiber forming layer materials 2 or the combination of the tile carpet 1 and the fiber forming layer material 2, The fiber-bonding portions 64 of the fiber-forming layer material 2 or the backing layer 3 and the fiber-bonding portions 64 of the fiber-forming layer material are bonded to each other with or without the reinforcing sheet 7 interposed therebetween. This is a method for producing a block-shaped sheet material in which fiber assembly layers 65 are disposed on both surfaces of the synthetic resin layer.

  For example, when the block-shaped sheet material 200 as shown in FIG. 6B is manufactured, specific examples of the manufacturing method of the sheet material include, for example, the normal tile carpet 1 and the fiber-forming layer material 2. The backing layer 3 and the fiber bonding portion 64 may be configured to face each other and bonded to each other with or without the reinforcing sheet 7 interposed therebetween, whereby the backing layer 3 and the fiber bonding portion are formed. Thus, the block-shaped sheet material 200 configured so that the fiber assembly layer 65 is disposed on both surfaces in the joint portion of 64 can be easily obtained.

  The penetration resistance value to be described later in the present invention is a standard representing the strength of a protective mat defined in ASTM D48332 and adopted by the Japan Impervious Construction Association, and is a protective mat fixed at six points with an iron rod having a diameter of 8 mm. The center part of the water is pushed at a speed of 300 mm per minute to display the force when penetrating, and the Japan Impervious Work Association is demanding to withstand a force of 500 N (Newton) or more.

  In the present invention, the impervious work is a waterproof work on the ground of the entire final disposal site as shown in FIG. 12 in order to prevent mixing of ground water and contaminated water that has passed through the waste in the final disposal site of industrial waste. It means to do.

  That is, as a specific example of the impermeable work in the final disposal site of the industrial waste, the sheet material 100 according to the present invention is placed inside the hole 46 excavated in the ground to be the industrial waste disposal site. The protective mat 100 is used in combination with a normal water-proofing or waterproof layer 47, and the protective mat 100 is used to protect the water-proofing or waterproof layer 47 applied to two layers. It is arranged in three layers on the lower, middle and upper parts of the water-impervious or waterproof layer 47.

The plurality of fiber-forming layer materials 2, 2 ', 2 "... or the tile carpets 1, 1', 1" with the plurality of fiber-forming layer materials 2, 2 ', 2 "... The tile carpet 1, 1 ′, 1 ″ or the fiber forming layer material 2, 2 ′, 2 ″,... After being arranged adjacent to each other and arranged such that at least a part of the edge portions overlap each other. The backing layer 3 or the fiber bonding portion 64 is heated by an appropriate heating means 40 to melt the remaining backing layer or the fiber-forming layer material 2 and one of the adjacent tile carpet or fiber-forming layer material. Adhering to the part continuously At the same time as forming the sheet material 100, an appropriate reinforcing sheet 7 such as a vinyl chloride sheet is provided on the fiber bonding portion 64 side so that the fiber assembly layer 65 in each fiber forming layer material 2 forms an outer surface. A cross-sectional view of a process of making a long sheet material 100 having a loop surface on one side by bonding and performing a bonding process using an appropriate cooling roller 41 is shown.

That is, FIG. 13 shows an example of a manufacturing method of the sheet material 100 in a state where the fiber assembly layer 65 is attached to one side of the reinforcing sheet 7, but it is separately formed on one side of the reinforcing sheet 7. The tile carpet 1 or the above-described fiber forming layer material 2 and the like are arranged adjacent to each other in an appropriate shape, for example, another continuous sheet material formed by the heating means in FIG. The sheet material 100 formed into a long shape having loop surfaces on both sides can be obtained by joining them to each other through 41 steps and then cutting them to a predetermined size.

Alternatively, a plate-like sheet material 100 having a fiber aggregate layer surface made of cut pile or the like, or the tile carpet 1 or the fiber forming layer material 2 are bonded to each other with a phase shifted, and cut into a predetermined size. It can be formed into a long sheet material 100 having a surface of a fiber assembly layer 65 made of a loop pile or a cut pile on both sides that can be aligned, and can be used as a waterproof layer or a protective layer for a water shielding layer.

  Moreover, if outdoor (tile) tile carpets using a plate-like sheet material 100 having surfaces composed of the fiber assembly layers 65 on both sides are laid on a concrete ground generally used in urban elementary and junior high schools, Injuries caused by falls of children can be reduced.

  Moreover, the above-described sheet material 100 according to the present invention can be used as a floor finishing material as a tile carpet having a loop layer on the lower surface or a fiber forming layer material.

  In this case, as the sheet material 100 in the present invention, when a fiber assembly layer 65 in which a large number of loop-like fibers such as loop piles are formed on the lower surface, the sheet material 100 is a predetermined sheet material. When laying down on a flooring material, an adhesive material is provided on a part of an appropriate surface bonding material (surface fastener, for example, Velcro [registered trademark]), for example, on one surface, on the predetermined flooring material, The sheet material 100 is attached to the floor material in the same principle as a hook-and-loop fastener by previously attaching a member having a large number of hook-shaped portions engaged with the loop to the surface of the surface using the adhesive. Since it can be joined and fixed, it can be installed easily, and the construction method using conventional adhesives or adhesives can be greatly improved.

  EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to the examples.

Example 2
The collected tile carpet (total thickness 6.5 mm, vinyl chloride backing layer thickness 3.0 mm) is placed in a heating furnace at 200 ° C. for 2.5 minutes using the processing apparatus shown in FIG. The surface temperature of the vinyl chloride backing layer of the carpet was heated to 140 ° C., and the gap 23 between the pair of rolls was passed through so that the vinyl chloride backing layer was on the roll side with the higher rotation speed.
(This pair of rolls was previously set to a roll gap of 1.2 mm, a roll temperature of 30 ° C., and a rotation difference of 4.2 times.)
The weight ratio of the fiber aggregate layer of the collected tile carpet to the vinyl chloride backing layer as the backing layer was about 13 to 87. As a result of separation into two layers through this process, a part of the vinyl chloride backing layer was obtained. Can be separated into a fiber forming layer material (39% by weight) and a pure vinyl chloride backing layer (61% by weight) containing a fiber bonding portion adhered in powder form.

Example 3
Two recovered fiber forming layer materials are heated to 175 ° C. using an infrared heater, and the fiber bonding portions are overlapped facing each other so that the loop layer of the fiber assembly layer 65 of the fiber forming layer material comes outside. The block-like sheet material which has a loop surface on both surfaces was obtained by laminating and pasting through a rolling press at 25 ° C. After that, it was cut to a size of 450 × 450 and used as a protective material for the waterproof layer on the bottom surface of the green roof.

Example 4
The collected plurality of tile carpets and the plurality of fiber-forming layer materials are heated to 175 ° C. using an infrared heater, and one of the 0.5 mm thick vinyl chloride long sheets as a reinforcing sheet is used. The tile carpets are arranged adjacent to each other so that the backing layer of the tile carpet comes into contact with each other, and the fiber bonding portion of the fiber forming layer material comes into contact with the other surface of the reinforcing sheet. The tile carpet and the fiber aggregate layer 65 of the fiber-forming layer material are arranged so as to face each other through the reinforcing sheet so that the loop layers of the tile assembly and the fiber assembly layer 65 of the fiber-forming layer material are both outside. The arrangement phase between the fiber-forming layer materials is shifted and overlapped, and after passing through a rolling press at 25 ° C, the surfaces are looped by trimming to a size of 2m x 20m. That to obtain a sheet material 100 which is formed in an elongated shape.

  Since the penetration resistance value of this long sheet material showed 650 N, it could be used as a protective layer for a water shielding work in a final disposal site for industrial waste.

Example 5
One of the collected used tile carpets is a fiber-forming layer material 2 having a displacement release treatment surface 4 formed by separating 65% of the vinyl chloride backing layer, and the other sheet is the collected used tile carpet. As it is, the fiber bonding part side and the backing layer side are overlapped so that the fiber assembly layer having the respective loop layers comes to the outside, and they are pasted through a rolling press at 25 ° C., and looped on both sides. A block-like sheet material having a surface was obtained. Thereafter, the unit plate-like material was trimmed to a size of 450 × 450, dyed green, and applied to the concrete base using a hook-and-loop fastener, and used as a ground carpet for an elementary school.

  According to the method for separating and collecting the fiber assembly layer and the backing layer from the tile carpet according to another aspect of the present invention, the collection and disposal when the used tile carpet, which has been a problem in the past, is disposed as industrial waste. In order to solve the processing method, an effective and economical effective method for reclaiming the tile carpet as a resource without discarding the tile carpet is provided.

  That is, in the above-described aspect of the present invention, the fiber assembly layer and the backing layer can be reliably and easily separated from the tile carpet in an easy and economical manner, and the fiber assembly layer can be reused. The backing layer can be reused simply by heating and softening by utilizing the properties of the thermoplastic resin.

Next, in the present invention, a method for separating the carpet or tile carpet 1 into the backing layer 3 and the fiber-forming layer material 2 constituting the carpet, and another separation method and apparatus different from the above-described separation method will be described below. Explained.

  That is, according to the separation method in this specific example, as shown in FIG. 20, a fabric layer 66 and a fiber layer having a pile layer in which a plurality of fibers are planted on one surface of the fabric layer 66 are formed. From the carpet or tile carpet 1 composed of the aggregate layer 65 and the backing layer 3 containing a synthetic resin formed on the surface of the base fabric layer 66 opposite to the surface on which the fiber aggregate layer 65 is formed, In this method, the backing layer 3 and the fiber-forming layer material 2 including the fiber assembly layer 65 are peeled from each other, and the tile carpet 1 is peeled by heating while keeping the tile carpet 1 flat. In this state, while moving in a direction having a horizontal component, the carpet is configured so that the moving direction of the tile carpet 1 is sharply bent downward at a predetermined portion so that the two are separated. This is a peeling method of

  If the configuration of this example is described in more detail, the traveling direction of the tile carpet 1 while moving the heated tile carpet 1 in a horizontal direction or a similar direction using an appropriate conveying means 202. Characterized in that the backing layer 3 and the fiber-forming layer material 2 separated from each other by abruptly changing in the downward direction including the vertical direction are taken up using appropriate take-up means 204, 205. It is.

  On the other hand, as an apparatus for specifically realizing the carpet peeling method according to the present invention, as shown in FIG. 20, a plurality of fibers are implanted on one surface of the base fabric layer 66 and the base fabric layer 66. And a backing layer containing a synthetic resin formed on the surface of the base fabric layer 66 opposite to the surface on which the fiber assembly layer 65 is formed. 3 is a device 220 for peeling the backing layer 3 and the fiber-forming layer material 2 including the fiber assembly layer from each other, the carpet peeling device 220 flattening the tile carpet 1. The carpet conveying means 202 for moving in the direction having the horizontal component while being moved while moving in the direction having the horizontal component while maintaining the shape, the means 201 for heating the carpet, Petto and a moving direction changing means 203 of the carpet provided at an appropriate site of the conveying means 202.

  The carpet moving direction changing means 203 is provided at the end of the carpet conveying means 202, and has a function of abruptly changing the moving direction of the tile carpet 1 in the downward direction including the vertical direction. Is preferred.

  In this specific example, the carpet conveying means 202 is constituted by a conveyor belt, and the moving direction changing means 203 of the tile carpet 1 is a support roller 206 that changes the moving direction of the conveyor belt 202. The support roller 206 preferably has a diameter of Φ25 to Φ150.

  Furthermore, in this specific example, each of the fiber forming layer materials 2 including the backing layer 3 and the fiber assembly layer 65 of the tile carpet 1 separated from each other in the vicinity of the moving direction changing means 203 of the tile carpet 1. It is desirable to provide a backing layer take-up means 204 and a fiber-forming layer material take-up means 205 for individually taking up the fibers.

  In the present invention, while moving the backing layer in close contact with the conveying means, the moving direction of at least the backing layer of the carpet is sharply bent, and then the traveling direction of the fiber-forming layer material is advanced by the backing layer. It is desirable to set the direction different from the direction.

  In the specific example of FIG. 20, the moving direction of at least the backing layer 3 of the carpet 1 is sharply bent while moving the backing layer 3 in close contact with the conveying means 202, and then through the backing layer take-up means 204. Then, the traveling direction of the backing layer 3 is reversed so that the backing layer 3 comes into contact with the conveyor belt 202, and the traveling direction of the fiber forming layer material 2 is determined using the fiber forming layer material take-up means 205. It is configured to set in a direction different from the direction.

  In the specific example of FIG. 21A as another specific example of the present invention, the bonding force between the backing layer 3 and the conveyor belt 202 is applied to the backing layer without using the backing layer take-up means 204. 3 and the fiber-forming layer material 2 are set so as to be larger than the bonding force between them to realize separation and separation of the two. In the specific example of FIG. 21B, FIG. Contrary to the specific example, the backing layer 3 of the tile carpet 1 is faced up and brought into contact with the conveyor belt 202, while the fiber forming layer material 2 of the tile carpet 1 is faced down to the upper surface of the mesh belt 210. Heating is performed to an appropriate temperature by the heat from the hot air generating means 211 which is an appropriate heating means while in contact.

  In this specific example, the backing layer 3 is inverted upward, but the fiber-forming layer material 2 is taken up in the vertically downward direction.

  Further, in the specific example of FIG. 21C, a conveyor belt made of a mesh belt while the tile carpet 1 moves downward while being sandwiched between a pair of conveyor belts 202 and 210 formed in the vertical direction. Heating is performed by appropriate heating means provided inside 210, for example, hot air generating means.

  And the heating tile carpet 1 is the part of the moving direction conversion means 203 provided in the lower end part of the conveyor belt, and the bonding force between the backing layer 3 and the conveyor belt 202 is the same as that of the backing layer 3. If it is set larger than the bonding force with the fiber forming layer material 2, the traveling direction of the backing layer 3 is different from the traveling direction of the fiber forming layer material 2 as shown in the figure. Delamination separation is realized.

  At this time, if appropriate joining means and friction improving means are arranged on the surface of the mesh belt 210, the fiber forming layer material 2 is taken up by the conveyor belt 210 and conveyed to an appropriate processing position. Is possible.

  The heating means 201 in this specific example is not particularly limited, and a known heating device can be used.

Furthermore, the carpet conveying means 202 in this specific example is desirably a conveyor belt 202 set so that the tile carpet 1 is disposed in a horizontal plane or a plane similar thereto, more preferably, Teflon. (Registered trademark) or a conveyor belt having a base material coated with Teflon (registered trademark) .

  On the other hand, the moving direction changing means 203 of the carpet used in this specific example has a function that can rapidly change the traveling direction of the tile carpet 1 at a predetermined portion.

  That is, as shown in FIG. 20, the carpet moving direction changing means 203 rapidly changes the traveling direction of the heated tile carpet 1 that has moved substantially in the horizontal direction downward in the vertical direction. It is configured.

  The substantially horizontal direction takes into consideration that the carpet layer may be transferred along a plane having some angle even if the transfer direction of the carpet is not a complete horizontal direction.

  As a specific example, as shown in FIG. 20, a support roller or tension roller 206 of the conveyor belt constituting a part of the carpet conveying means 202 is provided at the end of the conveyor belt 202, and the support roller or By making the diameter of the tension roller 206 as small as possible, the backing layer 3 and the fiber-forming layer material 2 of the tile carpet 1 can be easily separated.

  That is, in this specific example, since the sufficiently heated carpet or tile carpet 1 is changed by the tension roller 206 having a small diameter, the traveling direction of the carpet or tile carpet 1 is changed to a substantially right angle. The fiber-forming layer material 2 composed of the fiber assembly layer constituting 1 and the backing layer 3 are separated and separated independently.

  The peeling surface of the fiber forming layer material in this specific example has a shape as shown in FIG.

Here, to explain the configuration of this specific example, the vinyl chloride backing material (that is, the backing layer) 3 of the tile carpet 1 that has been heated to a sufficiently high temperature sticks to the conveyor belt 202 coated with Teflon (registered trademark ). become.
At this time, when the diameter of the tension roll 206 of the conveyor belt 202 forming the moving direction changing means 203 is small (for example, Φ25 to Φ150), the fiber assembly layer 65 is peeled off from the boundary surface with the vinyl chloride backing layer 3 by its own weight. It hangs down.

  On the other hand, since the vinyl chloride backing layer (backing layer) 3 is barely attached to the conveyor belt 202, the fiber assembly layer 65 constituting the fiber forming layer material 2 is made of the vinyl chloride backing layer. When the amount of peeling from the ring interface with 3 and hanging down by its own weight increases, it is dragged down by the weight of the fiber-forming layer material 2.

Therefore, the vinyl chloride backing layer 3 that is sticking to the Teflon (registered trademark) coated conveyor belt 202 just before the moment is captured, and the backing layer take-up means 204 is provided so that the backing layer 3 is placed on the conveyor 202. The backing layer 3 and the fiber-forming layer material 2 can be peeled and separated if they are pressed or held and discharged in an appropriate state to help the fiber-forming layer material 2 peel off due to their own weight.

  Similarly, it is also desirable to provide a fiber forming layer material take-up means 205 having a function of actively taking down the fiber forming layer material 2 downward.

  If the diameter of the tension roll 206 of the conveyor belt 202 in this specific example exceeds Φ150, the peeling force does not act on the fiber assembly layer 65, and it will fall while being stuck together with the backing layer 3.

Therefore, the smaller the diameter of the tension roll 206 is, the easier it is to peel off, but if the diameter is Φ25 or less, it is too small and the glass fiber breakage stress used for the core material of the conveyor belt 202 coated with Teflon (registered trademark) appears. And so on.

  Therefore, the diameter of the tension roll 206 is Φ25 to Φ150, preferably Φ50 to Φ100.

  Further, in this specific example, if there is a heating device that can sufficiently heat and a tension roll having an appropriate diameter, peeling is possible even without a friction roll.

  In the present invention, the tile carpet or the recycled tile carpet is heated when appropriately separating the carpet, or the recycled tile carpet or the like that is obtained by attaching the original carpet to the tile carpet or the recycled tile carpet. However, as the heating method, it is possible to immerse them in a heated solution, or to use appropriate heating means using heated air or steam.

  The use of hot water is preferable because it can also cause the carpet to be washed.

  In particular, when steam or superheated steam is used, the cleaning power is strong and dirt such as oil can be cleaned, and sand buried between piles and pests can be removed. .

  Further, in the present invention, the bonding force between the backing layer constituting the carpet and the fiber assembly layer constituting the carpet layer is formed by sharply bending the moving direction of the carpet in the heated state. Or it becomes possible to reduce adhesive force.

  The fiber assembly in which the bonding force between the backing layer and the backing layer holding member in contact with the backing layer after the carpet has passed through the bent portion constitutes the backing layer and the carpet layer. By configuring so as to be larger than the bonding force between the body layers, the peeling of the carpet is realized by changing the traveling direction of the backing layer and the fiber assembly layer.

  In the specific example of FIG. 20, the tile carpet is moved along a predetermined path while being supported by an appropriate conveyor belt 202. After passing through the moving direction changing means 03, the backing layer 3 and the backing layer are moved. The bonding force between the backing belt and the conveyor belt 202 that is in contact with the backing layer 3 is larger than the bonding force between the backing layer and the fiber assembly layer 2 constituting the carpet layer. By doing so, the backing layer separates from the fiber assembly layer 2 as the traveling direction of the conveyor belt 202 changes, and the separation is completed.

  Therefore, it is desirable that an appropriate means for increasing the bonding force between the backing layer 3 and the conveyor belt 202 is provided on the surface of the conveyor belt 202.

Explaining this specific example of the carpet peeling device 220 described above, the vinyl chloride backing material (backing layer) 3 of the tile carpet 1 heated at 200 ° C. through the heating device 201 is a conveyor coated with Teflon (registered trademark). Although it seems to stick to the belt 202,
On the conveyor belt having a conveyor belt tension roll diameter of 75Φ, the fiber-forming layer material 2 was peeled off from the boundary surface with the vinyl chloride backing layer 3 and hanged down by its own weight. When the amount of the fiber-forming layer material 2 that peels off from the boundary surface with the vinyl chloride backing layer 3 and hangs down by its own weight increases, the vinyl chloride backing layer 3 is dragged down by the weight of the fiber-forming layer material 2. Therefore, it is necessary to catch this moment and stick it to the conveyor belt 202 coated with Teflon (registered trademark) .
Therefore, pressing the vinyl chloride backing layer 3 with the backing layer take-up means 204 that functions as a holding jig, and the fiber-forming layer material 2 is peeled off by its own weight is an example of the fiber-forming layer material take-up means 205. The vinyl chloride backing material 3 and the fiber-forming layer material 2 could be separated and separated by assisting with a hook jig.

Example 7
Next, further specific examples of the present invention will be described in detail.
In this specific example, as shown in FIG. 21 (A), a plurality of carpets 92 on the opposite side to the side on which the fiber assembly layer is formed (that is, the back side) 94 is formed in a long shape. Without using or using appropriate reinforcing sheets while arranging the fiber aggregate layer 65 of the tile carpet 1 or the backing layer 3 of the fiber forming layer material 2 or the fiber bonding portion 64 adjacent to each other, A long sheet material is formed by bonding via an adhesive or a bonding agent.

  In this specific example, it is naturally possible to manufacture a recycled tile carpet 93 having a bonded structure as shown in FIG.

  The adhesive or bonding agent used in this specific example is desirably a double-sided pressure-sensitive adhesive tape 88 or a double-sided pressure-sensitive adhesive tape 88 based on a mesh sheet.

  Moreover, it is desirable that the mesh-like sheet base material of the adhesive has 5 to 10 mesh.

  On the other hand, when the recycled tile carpet formed by the above method is peeled off, the sheet material is immersed in a heating solution, or by using an appropriate heating means using hot air or steam, from the sheet material. It is possible to easily separate the tile carpet or the fiber-forming layer material from the carpet original fabric.

  In other words, the fiber forming layer material 2 composed of the fiber assembly layer 3 attached with the double-sided adhesive tape 88 and the carpet raw fabric 92 can be easily peeled off by performing an appropriate heat treatment. is there.

More specifically, since the double-sided adhesive tape 88 is vulnerable to heat, the recycled tile carpet formed by adhering the fiber-forming layer material 2 or the tile carpet 1 and the carpet original 92 with the double-sided adhesive tape 88. Alternatively, when the recycled carpet 93 is used at a later date and it is necessary to separate the fiber-forming layer material 2 or the tile carpet 1 and the original carpet 92,
For example, the fiber forming layer material 2 and the carpet raw fabric 92 are joined by applying heat to the double-sided pressure-sensitive adhesive tape 88 by applying a heat treatment such as immersing the recycled carpet in hot water. Since the double-sided pressure-sensitive adhesive tape 88 can be dissolved by heat, both can be easily separated and peeled off.

In this specific example, the temperature at which the surface adhesive tape 88 is weakened by heat differs depending on the adhesive used for the double-sided adhesive tape 88. Therefore, after examining the temperature characteristics of the adhesive, it depends on the application. Although it can be used properly,
(1) The manufacturer and the separator / collector are often different.
(2) Be a heat source available for everyday use
(3) Hot water at 100 ° C. is preferably used because the used tile carpet needs to be cleaned.

In this specific example, the carpet raw fabric 92 and the fiber forming layer material 2 or the fiber aggregate layer 65 of the tile carpet 1 are arranged so as to be on the outside, and an appropriate adhesive is used by overlapping them.
Use vinyl chloride sol for vinyl chloride backing material, or use double-sided adhesive tape or double-sided adhesive tape whose base material is a mesh material of 5 to 10 mesh, and cut it to a predetermined size by an appropriate method on the back side A tile carpet having a loop layer can be manufactured.

  In other words, if the mesh is finer than 10 mesh, the mesh hole is buried in the double-sided adhesive, and the expected air permeability cannot be obtained. If the mesh is less than 5 mesh, the mesh is too rough and The uniform bonding function cannot be fully exhibited.

Furthermore, in this specific example, the adhesive is a pressure-sensitive adhesive material comprising a double-sided pressure-sensitive adhesive tape, and when applying a long sheet material formed in a wide width or an unused carpet sheet,
It is also preferable that the marking is made using appropriate equipment.

In this example, as technical characteristics;
(1) When a product in which different materials are combined becomes industrial waste, it is easy to separate and separate each material.

  (2) Commodities combined from different materials can be separated and separated using a readily available heat source, and at the same time, the separated and separated materials can be easily reused.

  (3) By sticking together with double-sided adhesive tape, the long sheet material and unused raw carpet can be pasted together.

Example 8
Place the long sheet material formed in a wide and long shape and the unused raw carpet sheet so that each loop layer comes to the outside, and stick them together using double-sided adhesive tape,
A tile carpet having a loop layer was formed on the back surface obtained by trimming to a predetermined size by an appropriate method. When adopting the double-sided pressure-sensitive adhesive tape, one having a temperature characteristic of 100 ° C. and an adhesive strength of 30% at normal temperature (25 ° C.) was selected.
The tile carpet that is formed is a tile carpet that has a loop layer on the back side, and can be applied to the floor base with hook-and-loop fasteners (Magic Tape, registered trademark) and can be sticky like when using an adhesive. Because there is no electrician,
It was well received by computer wiring engineers. In addition, since the adhesive of each loop layer is pasted with a double-sided adhesive tape, a long sheet material formed in a wide and long shape and an unused carpet raw material are bonded together.
Later, when this tile carpet was used, and when it was necessary to separate and separate the two, it was confirmed by experiments that it could be easily peeled off with hot water at 100 ° C.

  The double-sided pressure-sensitive adhesive tape described above can be used when the backing layer 3 of the carpet or tile carpet used in the present invention and the fiber assembly layer 65 constituting the carpet layer are bonded and bonded.

  Since the present invention employs the technical configuration as described above, the following operational effects can be obtained.

  (1) Conventionally, from tile carpet waste that had to be discarded at a managed industrial waste disposal site or incinerated, heated and gripped with a pair of gripping means, or peeled off, The fiber forming layer material and the vinyl chloride backing layer can be separated by a simple operation and process using a cutting means such as a scraper blade.

  (2) According to the method used in the present invention, carpet fiber waste is not mixed in the separated vinyl chloride backing layer, and the backing layer has a very high purity. It is extremely useful for reuse as a raw material for flooring.

  (3) Further, according to the method used in the present invention described above, the separated fiber-forming layer material contains about 50% of the vinyl chloride backing layer, but it can be disposed of in an unmanaged industrial waste disposal site. The weight of the vinyl chloride backing layer is reduced from about 87% before the recovery process to about 50% after the recovery process. Therefore, for example, it is advantageous in the case of incineration, and a reusing method as nylon itself is opened.

  (4) Furthermore, according to the method used in the present invention, the noise is less and the energy consumption is smaller than in the conventional method. Furthermore, according to the separation and recovery method of the present invention, a pulverizing step and a mowing step are not required, so that carpet fiber waste and other dust are not generated, which is extremely excellent in terms of work environment and worker health.

  (5) Also, the fiber-forming layer material obtained by the present invention, used or new carpet or tile carpet is appropriately combined to form a reusable long or block sheet material, which is conventionally discarded. As a result, new uses of carpet and tile carpet waste, which has become a problem, are secured, so that it is possible to turn waste into useful resources and at the same time greatly contribute to environmental conservation.

(6) The present invention makes it possible to recycle and reuse tile carpets as 100% resources. By recycling 20 million m ² (100,000 tons) of waste annually, we achieved zero emissions in the tile carpet field. The social significance of what can be done is immeasurable.
