Description

  The present invention relates to a waist back fabric provided on the back side of waist equivalent parts such as trousers and skirts.

  There are many trousers or skirts formed by attaching the waist back fabric. In most cases, the waist back fabric is attached to improve the design of trousers or the like, or as a measure against slipping of trousers or the like. However, it can be said that the present situation is that there is almost no waist back structure formed by sufficiently examining the comfort of the waist when wearing trousers, that is, the wearer's feeling of wearing such as trousers. .

  For example, as an example of the back of a waist for the purpose of preventing slipping such as trousers or a skirt, Patent Document 1 discloses “the back of the waist with a slip stopper”.

  The lower back according to Patent Document 1 is formed by a belt attached along the waist around a trouser or the like. Further, the belt is provided along a longitudinal direction of the belt at a predetermined portion in the width direction. A long and slender antiskid made of silicon resin is attached by sewing.

Since it forms in this way, a convex part will be formed in the site | part corresponded to anti-slip | skid in the said waist back, if it sees in cross section.
Therefore, when pants etc. are worn, it can prevent that the convex part in the above-mentioned slip prevention contact | abuts around a waist, and pants etc. slide down.

  However, the silicone resin that forms the anti-slip has rigidity compared to the band, and such a convex anti-slip intensively abuts around the waist. While wearing, you will always feel the anti-slip feel against the waist.

  That is, the back of the waist according to Patent Document 1 is formed with a focus on how to prevent slipping, and it must be said that no consideration has been given to the wearing feeling.

In addition, there are documents that focus on improving the feeling of wear on the waist of trousers and the like.
For example, Patent Document 2 discloses an “adjustment structure” in which a waist portion of a slack (a waist equivalent portion) is formed to be stretchable in accordance with a change in waist size before and after a wearer's meal.

  However, the adjustment structure is formed of a plurality of members by separating the belt disposed on the waist portion of the slack in the length direction in order to form the adjustment structure to be stretchable in the length direction with respect to the waist portion of the slack. Furthermore, it is necessary to separately form an elastic band.

  That is, the “adjustment structure” according to Patent Document 2 needs to be formed with a complicated structure in order to improve the feeling of wearing, and thus has a problem that the manufacturing cost increases.

  In addition, the “adjustment structure” is certainly adjusted to a length corresponding to the wearer's waist size by stretching the elastic band, but that is not always true from the viewpoint of adhesion to the waist. It is not always possible to obtain a comfortable wearing feeling.

  Therefore, the present invention aims to provide a waist back fabric that can not only have a complicated configuration but also have a function of preventing slipping and the like, and can significantly enhance the wearing feeling.

  The waist back fabric of the present invention uses a fabric which is a knitted fabric, a woven fabric, or a nonwoven fabric, and / or a fabric obtained by deforming these fabrics, on the back side of the waist portion of a lower garment such as trousers or a skirt, or A waist backing fabric formed in combination with a thick fabric, which is formed with a thickness that can be in close contact with the waist of a human body in a surface contact state, and a surface received from the waist in the thickness direction of the waist backing fabric. It is characterized in that it is formed with elasticity that can be closely attached to the waist by an elastic force according to pressure.

  Further, the waist back fabric of the present invention is formed by confronting one surface layer and the other surface layer, and by connecting and returning the connecting yarns in order to ensure the elasticity in the thickness direction between the both surface layers. Preferably, the one surface layer and the other surface layer are connected and formed integrally.

  Further, the waist back fabric of the present invention has a plurality of small holes having a turtle shell shape in the surface layer on the waist contact side among the two surface layers of the one surface layer and the other surface layer. The surface layer on the side opposite to the surface layer on the waist contact side can be formed in a mesh shape finer than the turtle shell-shaped small holes.

  Moreover, the waist back fabric of this invention forms at least 1 thread | yarn among the thread | yarn which forms said one surface layer and said other surface layer, and said connection thread | yarn with the elastic thread | yarn which has a stretching property. Can do.

  Further, the waist back fabric of the present invention is formed by a two-layer structure in which one surface layer and the other surface layer are fixed in a surface contact state, and the one surface layer is a surface with respect to the waist of the human body. While having the thickness which can be closely_contact | adhered to a contact state, it forms with a flexible urethane foam, The said other surface layer can also be formed with the cloth which has a stretching property.

  Further, the waist back fabric of the present invention is formed by a two-layer structure in which one surface layer and the other surface layer are fixed in a surface contact state, and the one surface layer is formed on the surface of the human body. While having the thickness which can be closely_contact | adhered to a contact state and forming with a nonwoven fabric, you may form the said other surface layer with the cloth which has a stretching property.

  The above-mentioned flexible urethane foam is not particularly limited as long as the air bubbles communicate in the inside thereof and are soft and have a restoring force. In particular, a polyether-based foamed urethane foam is preferable. Since the polyether-based foamed urethane foam can be blended with a wide variety of raw materials, it can be formed according to the application from a wide range of performance such as elastic modulus.

  The stretchable fabric is not particularly limited as long as it is stretchable, and for example, a tricot fabric or a bias cut fabric can be adopted.

  Moreover, the waist back fabric of this invention can also perform an edge process in the state which has arrange | positioned the core material which has a stretching property in the length direction along the lower end part in the width direction.

The present invention also includes a garment equipped with the above-described waist back fabric according to the present invention.
Incidentally, the lower garment refers to clothes worn on at least the lower body such as other trousers such as jeans, a skirt, an inner, and ski wear.

According to the first aspect of the present invention, the waist back fabric according to the present invention is compressed in the thickness direction by the surface pressure received from the waist when wearing trousers or the like, and therefore contacts the waist in a planar shape. be able to. Moreover, since the waist back fabric has elasticity in the thickness direction, it can be in close contact with the waist with a firm contact force.
Therefore, it is possible to prevent the pants and the like from being displaced, and, of course, the wearer can obtain a good wearing feeling.

According to the invention described in claim 2, the waist back fabric according to the present invention is integrally formed by connecting the connecting yarns between the one surface layer and the other surface layer. .
Therefore, a gap (gap) exists between one surface layer and the other surface layer, that is, between the connected connecting yarns. For this reason, when the lower back fabric according to the present invention is brought into contact with the waist, in the summer, air permeability can be ensured by the space in the part where the connecting yarn is moved, and moisture and sweat can be prevented. Can absorb water.

  On the other hand, in the winter season, since the waist back fabric has a heat retaining effect by securing a space in the portion where the connecting yarn is moved, it is possible to secure heat retaining properties in the waist.

  Furthermore, the waist back fabric according to the present invention can be easily attached to a waist equivalent part such as trousers simply by sewing, for example, and can be formed without requiring a complicated configuration.

In addition, since the waist back fabric according to the present invention can be formed with elasticity in the thickness direction as described above, it is possible to adopt a configuration in which the waist-corresponding portion such as trousers is not easily relaxed.
That is, the waist back fabric according to the present invention can retain the shape of the waist part of trousers and the like so that it does not lose its shape, so that the appearance and texture can be improved, and a high-class feeling can be created.

  In addition, there are elastic yarns that come and go inside the waist backing fabric, and there are gaps between the multiple elastic yarns. Therefore, the waist backing fabric is formed with a sufficient thickness, but does not become heavy and can ensure a good comfort.

  According to the invention described in claim 4, aesthetic properties can be obtained by forming a number of turtle shell-shaped holes in the waist-contacting surface layer of the waist backing fabric, that is, by forming the entire surface layer with a honeycomb mesh structure. Of course, the strength of the entire surface layer can be secured.

Furthermore, since the surface layer on the waist contact side can be formed as a surface layer having excellent water absorption and breathability by forming the above structure, it actively absorbs moisture into the back fabric. Can be made. For this reason, the surface layer surface on the waist contact side can always be kept in a free-flowing state, and stuffiness can be prevented.
On the other hand, the surface layer on the waist contact side is formed by forming the surface layer on the opposite side in a fine mesh shape, while ensuring a certain degree of air permeability and absorbing sweat inside the waist backing fabric, etc. Can be stored so that the moisture does not flow out to the fabric side such as pants. Therefore, trousers etc. can always be kept clean.

  According to the device according to claim 5 or claim 6, the one surface layer is formed by securing a thickness and is formed of a soft urethane foam and a non-woven fabric, respectively. Since it is elastically deformed or deformed flexibly in the thickness direction, it is possible to prevent the pants and the like from slipping down, as in the case of the above-described waist back fabric. Of course, the wearer can obtain a good wearing feeling. It is possible to produce an effect of being able to.

  Furthermore, since the other surface layer is formed of a stretchable fabric, it can flexibly respond to the movement of the waist. Therefore, it has abrasion resistance, appearance, texture, etc. can be improved, and a high-class feeling can be created.

  In particular, the waist back fabric according to claim 5 or claim 6 can be configured with a simple structure as compared with the case where the waist back fabric is configured with a three-layer structure. For this reason, the cost of the waist back fabric can be reduced and the manufacturing time can be shortened.

  According to the device of the seventh aspect, in addition to the elastic force in the thickness direction, the one surface layer and the other surface layer can be supplementarily provided with stretchability. Accordingly, the waist back fabric expands and contracts in the width direction and the length direction in response to the movement of the wearer bending the waist or running, so that the wear feeling can be further improved and the waist Corresponding wear resistance can also be improved.

  According to the eighth aspect of the present invention, the waistline according to the present invention is formed by performing an edge processing in a state in which a core material having elasticity in the length direction is disposed along the lower end portion in the width direction of the waist backing fabric. For example, when a wearer such as trousers equipped with a back fabric performs a walking operation, a turning operation, and the like in a daily operation, the waist portion is required to swing or rotate around the waist. However, even in such a case, the core material arranged along the lower end expands and contracts in the length direction, that is, around the waist so as not to hinder the wearer's operation. It is possible to respond flexibly to the operation. Therefore, at the time of wearing, the waist back fabric is in close contact with the waist, but the wearer can maintain a good wearing feeling and the lower end of the waist back fabric does not relax. Therefore, it is possible to maintain a close contact state with the waist.

  In addition, for example, even when the waist is repeatedly expanded and retracted, such as a forward bending operation or a seating operation on a chair, the edge processing is performed with the core material arranged at the lower end of the waist backing fabric. By applying, the strength and form of the lower end can be ensured. Therefore, by repeating the above-described operation, the lower end portion of the lower back fabric is not inadvertently folded or relaxed, and durability can be improved.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a waist-corresponding portion 10a and a peripheral portion thereof in a slack 10 formed by including a waist back fabric 11 according to the present embodiment.

As shown in FIG. 1 above, the waist back fabric 11 according to this embodiment is formed in a belt shape and attached along the waist of the slacks 10. Further, as shown in FIG. 2, the waist backing fabric 11 is attached to the waist corresponding portion 10a of the slacks 10 by sewing with a sewing machine at each of the upper and lower portions in the width direction of the waist backing fabric 11. ing.
Here, the sewing at the upper portion in the width direction of the waist backing fabric 11 is set to the first sewing portion 12a, and the sewing at the lower portion in the width direction of the waist backing fabric 11 is set to the second sewing portion 12b. Set to.

Regarding the first sewn portion 12a, when the waist back fabric 11 is sewn to the waist equivalent portion 10a of the slacks 10, the waist equivalent fabric 11 and each upper equivalent portion of the waist equivalent portion 10a are They are folded back so as to face each other, and further, the seams 13a and 13b (folded pieces) formed by folding back are overlapped and sewn along the waist.
Incidentally, the waist back fabric 11 is attached to a position shifted downward with respect to the waist equivalent portion 10a of the slacks 10.

On the other hand, the second sewing portion 12b is sewn in a state where the waist back fabric 11 is directly opposed to the waist equivalent portion 10a of the slacks 10 on the lower side in the width direction of the waist back fabric 11. It is formed by doing.
Furthermore, when the waist back fabric 11 is attached to the waist equivalent portion 10a, the lower portion 14 further hangs down in a flap shape with respect to the second sewn portion 12b in the width direction of the waist back fabric 11 It becomes.

Further, as shown in FIGS. 3A and 3B, the lower end portion 18 in the width direction of the waist backing fabric 11 is edged with a core material 19 disposed.
Further, at the lower end portion 18 in the width direction of the waist backing fabric 11, the core material 19 is concealed by a polyethylene-based resin fine yarn while being integrally wound so as to be held. Although the polyethylene film formed in the thin strip | belt shape is used for the said core material 19, it is not specifically limited if it is a member which has a certain amount of elasticity while having a stretching property about the length direction.

Next, the structure of the waist back fabric 11 will be described.
The waist back fabric 11 is formed into a three-dimensional solid knitted fabric by a double raschel knitting machine. Specifically, as shown in FIG. 4B, the waist lining fabric 11 is formed by facing the outer material 15 and the lining material 16 with an interval (thickness) of about 4 mm. The connecting yarns 17 that connect the outer material 15 and the lining 16 are connected to each other by innumerablely forming them.
Incidentally, the outer surface 15 corresponds to the surface that contacts the waist when attached to the waist equivalent portion 10a of the slacks 10, and the lining 16 corresponds to the waist when attached to the waist equivalent portion 10a of the slacks 10. This corresponds to the surface that is superposed on the portion 10a.

  As described above, the distance between the outer material 15 and the lining 16, that is, the thickness of the lower back fabric 11, is about 4 mm, but of course is not limited to about 4 mm, for example, 1 mm to 8 mm. Although it is preferable to set between, it is not particularly limited as long as the waist back fabric 11 can be in close contact with the waist of the wearer when the slacks 10 are worn. .

  The outer material 15, the lining 16, and the connecting yarn 17 are all formed of a polyurethane elastic yarn (PUR (PU)) having elasticity.

  As shown in FIG. 4A, the outer surface 15 has a large number of turtle shell-shaped (hexagonal or honeycomb structure) small holes 15a formed in a mesh shape on the entire surface.

  On the other hand, as shown in FIG. 4 (c), the lining 16 is formed by a mesh-like mesh, and is formed by a finer mesh than the small holes 15a having the turtle shell shape. .

  The waist back fabric 11 in this embodiment shall be formed with the form mentioned above, and the effect | action and effect which the said waist back fabric 11 show | plays are demonstrated below.

  In the state where the slacks 10 provided with the waist back fabric 11 in the present embodiment is worn, the waist back fabric 11 abuts on the waist A of the wearer as shown in FIG. At this time, the waist A receives a surface pressure from the waist back fabric 11 according to the waist size of the wearer and the tightening force of the belt. On the contrary, the waist backing fabric 11 provided around the waist of the slacks 10 is elastically deformed in the direction in which the entire surface is compressed.

Specifically, the innumerable connecting yarns 17 arranged inside the waist back fabric 11 receive a compressive force (F1) by abutting against the waist A and buckle or contract. Thereby, the elastic force (F2) which tries to restore the waist back fabric 11 about the thickness direction acts (refer one part enlarged view in FIG. 5).
While this elastic force (F2) acts as a force to be in close contact with the waist A, the waist back fabric 11 in the waist equivalent portion 10a has an appropriate contact force (elastic force F2) according to the wearer's waist size and the like. It can adhere to the waist A.
Moreover, such an adhesion force can be applied to the entire surface of the lower back fabric 11.

  As described above, the slacks 10 do not fall with respect to the waist A, and the wearer does not feel a tightness, a pain, or the like, and can obtain a good touch that is in perfect contact.

  In addition, if the slack 10 is provided with the above-described waist back fabric 11, the waist of the wearer is not required, for example, without requiring a complicated structure such as forming the fabric itself in the waist-corresponding portion of the slack 10 to be stretchable. The structure which can adjust the waist size of the slacks according to size can be realized.

  In addition, since the wearer of the slacks 10 is usually in a state of wrapping a belt, the breathability of the waist A is significantly reduced by the belt, so that the waist A is easily stuffy and uncomfortable and hygienic. Not right.

  On the other hand, when the waist back fabric 11 in this embodiment is provided, as shown in FIG. 6A, the waist back fabric 11 between the fabric in the waist equivalent portion 10a of the slacks 10 and the waist portion A. It will be in the state which intervened. For this reason, the waist back fabric 11 which contact | abutted to the waist part A actively absorbs the sweat which the wearer sweated (refer the one-part enlarged view in Fig.6 (a)).

  Specifically, since moisture B such as sweat is absorbed into the inside of the waist backing fabric 11 through the numerous turtle-shell shaped holes 15a on the surface of the outer fabric 15, the outer fabric 15 in the waist backing fabric 11 is always free flowing. Can be kept in a state. For this reason, while being hygienic, the stuffiness etc. in the waist part A vicinity can be prevented.

  Furthermore, the lining 16 on the side where the belt and the fabric of the slacks 10 are formed is formed in a fine fine mesh on the surface, so that the waist equivalent portion 10a of the slacks 10 and the belt are secured while ensuring air permeability. Moisture B such as sweat on the side can be stored in the waist back fabric 11.

  Further, a space exists between the infinite number of connecting yarns 17 arranged inside the waist back fabric 11. Since this space exists even when the connecting yarn 17 is buckled due to compression, air circulates in this space, so that air permeability is also provided between the waist A and the waist equivalent portion 10a of the slacks 10. Can be secured.

On the contrary, in the winter season, the above-mentioned space existing inside the waist back fabric 11 has a heat storage action, and therefore the waist back fabric 11 can exert a heat retaining effect.
Further, as shown in FIG. 6B, in the state where the slacks 10 are removed,
The waist back fabric 11 is restored to the original thickness, and the space is widened. Therefore, the air permeability is improved and the moisture B can be more actively diffused to the outside.

Here, the moisture B absorbed inside the waist back fabric 11 can be positively evaporated through the surface material 15 having a large number of small holes 15a on the surface. Furthermore, since the outer material 15 and the lining material 16 are both air permeable, not only the inside of the waist lining fabric 11 but also, for example, odorous components adhering to the fabric of slacks etc. are actively diffused to the outside. Can be made.
Therefore, even if the slacks 10 are repeatedly worn, they can always be worn in a hygienic state.

  Further, as described above, the outer fabric 15 and the lining 16 in the waist lining fabric 11 are formed by using polyurethane elastic yarn so that they can be biaxially stretched. For this reason, the waist back fabric 11 according to the present embodiment is integrally formed with the waist equivalent portion 10a of the slacks 10 by the first sewing portion 12a and the second sewing portion 12b. In addition, it is possible to expand and contract within a certain range in each of the length direction and the width direction with respect to the waist equivalent portion 10a of the slacks 10.

  Accordingly, the outer fabric 15 and the lining 16 are flexibly expanded and contracted in accordance with the movement of the wearer bending forward and the operation of sitting on the chair, so that the waist back fabric 11 is not displaced with respect to the waist A. Further, it is possible to maintain a close contact state.

  In addition, the lower end portion 14 of the lower back portion 14, particularly the lower portion 14, particularly the lower portion 14 of the flap shape, can be made difficult to relax because the lower end portion of the waist backing fabric 11 is provided with the core material 19. The shape of the lower end portion 18 can be maintained.

The waist back fabric 11 in the present embodiment is not limited to the above-described form, and can be configured in various forms.
For example, the yarn constituting the outer fabric 15, the lining 16, or the connecting yarn 17 in the waist lining fabric 11 is not limited to the polyurethane elastic yarn as described above, but may be, for example, other polyester yarn that is not an elastic yarn. A resin fine thread may be used.

  For example, the connecting yarn 17 in the waist back fabric 11 is formed using polyurethane elastic yarn, but if it is configured to obtain adhesion to the waist A, it is not an elastic yarn, for example, a polyester yarn. It may be configured. In the case of adopting this configuration, when the polyester yarn is buckled, a restoring force can be applied by utilizing the rigidity of the polyester yarn itself. This restoring force can be applied as an adhesion force for closely contacting the waist.

Furthermore, the means for constructing the waist back fabric 11 in a three-dimensional structure is not limited to double raschel knitting as in this embodiment, and for example, knitting methods such as circular knitting, warp knitting, and weft knitting. Of course, it is not limited to a knitted fabric, and a woven fabric, a nonwoven fabric, a fabric obtained by deforming these fabrics, or a combination of these fabrics to form a three-dimensional structure may be used.
In addition, the waist back fabric may be formed by using twisted yarns, or may be deformed by twisting in the state of the fabric to form a three-dimensional structure.

Specifically, an example of the waist back fabrics 21 and 31 according to other embodiments having a configuration different from that of the waist back fabric 11 according to the above-described embodiment will be described below.
However, in the waist back fabric 21 according to the present embodiment, the same portions as those in the above-described configuration of the waist back fabric 11 are denoted by the same reference numerals, and the description thereof is omitted.

The waist back fabrics 21 and 31 according to the present embodiment have a two-layer structure as shown in FIGS. 7 and 8, respectively. That is, the waist backing fabric 21 shown in FIG. 7 and the waist backing fabric 31 shown in FIG. 8 are integrally formed by polymerizing the one surface layer 22, 32 and the other surface layer 23, 33 with each other. doing.
Incidentally, the waist back fabrics 21 and 31 are integrally configured by bonding the polymerization sites in the one surface layer 22 and 32 and the other surface layer 23 and 33 with a resin adhesive, Of course, it is not limited to the fixing method using the adhesive as described above, and for example, it may be integrally formed by welding by heat.

  Further, in the waist back fabric 21 shown in FIG. 7 and the waist back fabric 31 shown in FIG. 8, when the one surface layer 22, 32 is attached to the waist equivalent portion 10 a on the back side of the slacks 10, The surface layer on the side facing the corresponding portion 10a is set, and the other surface layers 23 and 33 are set on the surface layer in contact with the waist of the human body.

  Here, the waist backing fabric 21 shown in FIG. 7 is a polyether-based material that secures a thickness that allows the one surface layer 22 to be in close contact with the waist of the human body when the slacks 10 are worn. It is made of urethane foam.

  The other face layer 23 is a tricot fabric knitted by blending polyurethane yarn and nylon yarn.

  On the other hand, the waist back fabric 31 shown in FIG. 8 has a thickness that allows one surface layer 32 to be in close contact with the waist of the human body by a non-woven fabric instead of polyether foamed urethane. Formed.

  Further, the other surface layer 33 in the waist back fabric 31 shown in FIG. 8 is composed of the same material and the same knitted fabric as the other surface layer 23 in the waist back fabric 21 shown in FIG.

  As described above, the waist back fabric 21 and the waist back fabric 31 can be configured, and both can exhibit the following operations and effects.

  For example, the one of the surface layers 22 and 32 is formed by securing a thickness capable of being in close contact with the waist of the human body in a surface contact state, and has a polyether-based foamed urethane and a nonwoven fabric having elasticity and stretchability. Therefore, it can be elastically deformed in the thickness direction according to the wearer's waist size when the slacks 10 are worn, and can be in close contact with the waist. Therefore, the wearer of the slacks 10 can obtain a good fit.

  The other surface layers 23 and 33 have dense eyes, but can ensure air permeability and allow moisture such as sweat to pass to the one surface layers 22 and 23 side. Can do. The one surface layer 22 is made of polyether-based urethane and has many fine pores. Since the one surface layer 32 has a space between the intertwined fibers, the one surface layer 22, Water such as sweat that has passed from the 32 side can be stored.

  In addition, by configuring the other surface layers 23 and 33 on the side in contact with the waist with a tricot fabric, the waist and back fabrics 21 and 31 have a certain degree of stretchability in the width and length directions, Since the eyes are dense, wear resistance can be improved. In addition, a high-class feeling can be created from the viewpoint of appearance and texture.

  Thus, the waist back fabrics 21 and 31 according to the present embodiment can exhibit substantially the same operations and effects as the waist back fabric 11 described above.

  In particular, the back and back fabrics 21 and 31 according to the present embodiment can be configured with a simple structure as compared with the three-layer structure by configuring with a two-layer structure. By polymerizing with an adhesive, it can be constructed more easily than when it is constructed integrally by sewing. For this reason, the cost of the waist back fabrics 21 and 31 can be reduced and the manufacturing time can be shortened.

  The polyether-based urethane foam constituting one surface layer 22 of the waist backing fabric 21 according to the present embodiment has high stretchability in the width direction and the length direction of the waist backing fabric 21 in addition to the thickness direction. Have. Then, by polymerizing the other surface layer 23 configured to have high stretchability like the polyether-based urethane foam, the stretchability in the width direction and length direction of the waist backing fabric 21 may be impaired. In addition, it is possible to maintain high stretchability as the entire waist backing fabric 22.

  Further, the waist back fabric is not limited to being attached to the waist equivalent portion 10a of the slacks 10 by sewing, but adhesive, tape adhesion, heat welding, and the waist equivalent portion 10a itself. It can be formed by having the same function as the waist back fabric.

  Further, the waist back fabric 11 constituted by the above three-dimensional structure is not limited to being provided in the slacks 10 as in the present embodiment, but includes various other trousers such as jeans, skirts, inners, ski wears, and the like. It can be applied as a waist back fabric for clothing.

  In addition, the waist lining fabric 11 is configured to contain, for example, ceramic powder with respect to the yarn constituting the outer fabric 15 and the lining 16 or / and the connecting yarn 17 so that the far infrared effect can be exhibited. You may comprise by adding another effect | action supplementarily, including a deodorizing agent etc. and comprising.

In the correspondence between the above-described embodiment and the configuration of the present invention, the surface 15 of this embodiment corresponds to one surface layer constituting the three-layer structure of the present invention, and the lining 16 constitutes a three-layer structure. The outer surface 15 of this embodiment corresponds to the other surface layer constituting the three-layer structure of the present invention, and the lining 16 is one surface constituting the three-layer structure. Corresponding to the layer,
