Description

  The present invention relates to a laminated sheet for body that can reduce curing after bonding as much as possible, has high air permeability, and can realize stretchability and compression elasticity.

  In recent years, as an adhesive interlining, the dot method has been frequently used among random powders, dots and application shapes on honeycombs, and as an adhesive constituting the adhesive interlining, polyamide adhesive resin, polyester adhesive resin, Polyethylene adhesive resins and ethylene vinyl acetate adhesive resins are well known.

  Specifically, a non-adhesive resin containing a fine particle resin having a thermoplastic average particle diameter of 0.01 to 10 μm is printed as a first resin layer in the form of dots on the surface of the base fabric, and the first resin layer is printed on the dots. A thermoplastic resin is adhered as two resin layers. The thermoplastic resin of the second resin layer can be prevented from falling off, but the first resin layer is used as an adhesive interlining, particularly for improving the initial adhesive strength, the adhesive strength after dry cleaning, and the adhesive strength after water washing. The second resin layer is formed of a thermoplastic resin and is formed of a mixture of a crosslinkable resin, a thermoplastic fine particle resin, and a plasticizer (see, for example, Patent Document 1).

  In another conventional technique, a hot melt film made of a thermoplastic polyurethane resin and having excellent low temperature flexibility is proposed.

  Specifically, a composition comprising an aliphatic diisocyanate, a polymer diol and a low extender, wherein at least one component has at least one methyl group side chain in the molecule, particularly a polymer of a repeating unit having a side chain It is proposed to use a diol (see, for example, Patent Document 2).

JP 2003-193212 A JP-A-9-221640

  In the conventional technique described in Patent Document 1, the laminated sheet using the adhesive interlining can improve the initial adhesive strength, the adhesive strength after dry cleaning, and the adhesive strength after water washing, There is a problem that even if the initial adhesive resistance is large, the adhesive force decreases with the progress of peeling, and it is not possible to prevent a sufficient decrease in the adhesive force.

  Also, if there is a non-uniform distribution of the adhesive and a portion that is not bonded to the interlining, a wavy deflection or wrinkle will occur at the boundary between the bonded portion and the unbonded portion, and depending on the size of the applied shape, the surface In other words, linear defects are generated, the uniformity of the surface of the laminated sheet is lowered, the surface is rough, and the product quality is lowered.

  In addition, this conventional technique has a problem that the dot portion is hardened and the stretchability is significantly impaired.

  Moreover, in the conventional technique described in the said patent document 2, there exists a problem that the laminated sheet using the film which consists of a thermoplastic urethane resin reduces air permeability remarkably or hardly. Further, when a surface material made of a mesh sheet is laminated and bonded to this film, there is a problem that the adhesive resin oozes out from the surface material and so-called resin transfer occurs.

  Therefore, in each of the conventional techniques described in Patent Documents 1 and 2, various properties required for wearing on each part such as the chest, abdomen, buttocks, legs and arms of the body, such as air permeability, good Therefore, it is unsuitable as a laminated sheet for body use that is used by being worn on the body, and a laminated sheet for body use that solves such problems is desired. ing.

  An object of the present invention is to provide a laminated sheet for body that is excellent in air permeability, good touch, stretchability and compression elasticity.

  The present invention is a laminated sheet for a body characterized in that a planar surface material having elasticity and compression elasticity is bonded to at least one surface of an adhesive core made of a spunbond nonwoven fabric made of a thermoplastic elastomer resin. .

  According to the present invention, a planar surface material having elasticity and compression elasticity is bonded to at least one surface of an adhesive core made of a spunbond nonwoven fabric made of a thermoplastic elastomer resin. However, the laminated sheet-like surface material can be melted and bonded at the contact point, and the remaining portion can be maintained without being melted to maintain the initial elasticity. As a result, no crushing occurs, the surface material is bonded to the surface material with high peel strength, the raised state is maintained, excellent breathability, stretchability and compression elasticity are ensured, and good touch Can be realized.

  In addition, since spunbonded nonwoven fabric is made of thermoplastic elastomer resin, it can be bonded even if the surface material is made of different materials such as natural fiber, synthetic fiber and artificial leather. It can be applied to the surface material and has high versatility. In addition, since the surface material can be joined to one side or both sides of the spunbond nonwoven fabric by heating and compressing, the production is easy and the productivity is improved.

  In the invention, it is preferable that the thermoplastic elastomer resin is made of a resin having a JIS-A hardness of 65 to 95 degrees and a flow start temperature of 76 to 148 degrees Celsius.

  Furthermore, the present invention is characterized in that the non-woven fabric is fused with a filament having a low melting point polymer as a sheath.

  Furthermore, the present invention is characterized in that it is used for at least a part of women's underwear selected from brassiere, slip, body suit, girdle and shorts.

  Furthermore, the present invention provides a relaxation correction tool that is attached in a stretched state to a predetermined part selected from the chest, abdomen, buttocks, thigh, calf, arm, ankle, knee, elbow, waist, shoulder, and neck of the body It is used for at least a part.

  Furthermore, the present invention is characterized in that it is used for at least a part of a supporter that is attached to a predetermined part selected from an ankle, knee, elbow, waist, shoulder, and neck in an extended state.

  According to the present invention, since the adhesive interlining is made of a spunbond nonwoven fabric made of thermoplastic elastomer resin, a surface material having stretchability and compression elasticity is used as a surface or lining on at least one surface thereof. Since the filaments of the fiber assembly constituting the fiber are joined by so-called thermal bonding, which is melt-bonded in the form of dots, large peeling strength can be obtained without causing crushing as a core, and the raised state is maintained. At the same time, it has excellent breathability, stretchability and compression elasticity, and when the planar surface material is brought into contact with the skin of the body, excellent touch is obtained.

  In addition, since spunbonded nonwoven fabric is made of thermoplastic elastomer resin, it can be bonded even if the surface material is made of different materials such as natural fiber, synthetic fiber and artificial leather. This can be performed on the surface material, and high versatility can be realized. Moreover, since the spunbonded nonwoven fabric and the planar surface material can be joined by heating and compression, the production is easy and the productivity can be improved.
