DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive interlining and a garment using the adhesive interlining.

[0002]

2. Description of the Related Art Conventionally, various interlinings have been used in clothing to reinforce the weakness of the fabric by making use of the characteristics of the fabric. As one of these interlinings, there is a so-called adhesive interlining in which an adhesive is attached to one surface of a fiber sheet,
Since this adhesive interlining is excellent in the workability of adhering to the fabric,
It is preferably used. However, the conventional adhesive interlining has a problem in that, when the adhesive interlining is adhered to the cloth, the adhesive on the fiber sheet oozes out on the opposite surface of the fiber sheet, and iron slippage is deteriorated. In addition, in order to remove wrinkles of clothes formed by sewing the fabric with the bonded interlining,
In general, steam treatment is performed, but due to this steam treatment, the adhesive strength of the adhesive interlining is significantly reduced. When the clothes are worn, or when washed or dry-cleaned, the peeling does not work. There was a case.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide:
It is an object of the present invention to provide an adhesive interlining having a small amount of an adhesive on a fiber sheet exuding to the opposite surface of the fiber sheet and having a small decrease in adhesive force even when subjected to steam treatment, and a garment using the adhesive interlining.

[0004]

The adhesive interlining of the present invention has an adhesive on a fiber sheet. The adhesive contains an adhesive resin and a polyurethane having a blocked isocyanate group, and the weight of the adhesive is Is 100,
Polyurethane having a blocked isocyanate group (hereinafter referred to as “BI polyurethane”) accounts for 1 to 15% by weight. Therefore, when the adhesive interlining is adhered to the cloth, the blocking agent blocking the isocyanate group of the BI polyurethane is dissociated and the adhesive resin is cross-linked by the isocyanate group, so that the melt viscosity of the adhesive resin increases. In addition, oozing of the adhesive on the fiber sheet to the opposite side of the fiber sheet is reduced. Also, since the adhesive resin is cross-linked and the water resistance is improved, even if it is steamed,
Small decrease in adhesive strength.

[0005] The garment of the present invention uses a cloth to which the above-mentioned adhesive interlining is adhered, so that the iron is slippery, and the adhesive interlining is peeled off when wearing the clothes, washing or dry-cleaning. It does not mean to do.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As the adhesive resin contained in the adhesive of the adhesive interlining of the present invention, a polyolefin resin such as polyamide, polyvinyl chloride, polyester, polyurethane or polyethylene is used alone. Or mixed. Among these, polyamide-based and polyurethane-based adhesive resins have active hydrogen and have high reactivity with the isocyanate group of BI polyurethane, so that they can be suitably used. Polyamide-based adhesive resins have excellent adhesive strength with various fabrics. Therefore, it can be used particularly preferably.

[0007] The adhesive of the adhesive interlining of the present invention contains an adhesive resin and a BI polyurethane, and the weight thereof is 1%.
00, the BI polyurethane occupies 1 to 15% by weight (hereinafter, the description of the BI polyurethane by weight means that the weight of the adhesive resin and the BI polyurethane is 10%).
Since the adhesive resin is cross-linked at the time of bonding, it is possible to prevent the adhesive on the fiber sheet from seeping out to the opposite side of the fiber sheet, and to have water resistance, solvent resistance,
In addition, since the heat resistance is also improved, the decrease in the adhesive strength after the steam treatment is small, and the washing resistance and the dry cleaning resistance are also excellent. Furthermore, since it is a polyurethane, it has elasticity and elasticity, and has the advantage of not impairing the feeling.

If the amount of the BI polyurethane is less than 1% by weight, the melt viscosity of the adhesive resin does not become too high, so that the adhesive on the fiber sheet cannot be prevented from exuding to the opposite side of the fiber sheet, This is because the adhesive strength after the steam treatment is greatly reduced, and if it exceeds 15% by weight, the amount of the adhesive resin is reduced, and the initial adhesive strength is reduced.
In addition, when the fiber sheet has been subjected to the water-repellent treatment, 3 to
When 12% by weight, more preferably 5 to 10% by weight of BI polyurethane is mixed, and when the fiber sheet is not water-repellent, 1 to 10% by weight, more preferably 2 to 7% by weight of BI polyurethane is added. Mix. When a BI polyurethane reaction accelerator is included, the amount of the reaction accelerator is also considered as the weight of the BI polyurethane.

The more the number of contact points of the BI polyurethane with the adhesive resin, the more efficiently the crosslinking reaction can proceed. Therefore, when the average particle size of the adhesive resin is 1, the BI polyurethane is 0.1 or less. It is preferred to use a BI polyurethane having an average particle size. The average particle size of the adhesive resin used in the present invention is preferably about 20 to 80 μm in consideration of the workability and the degree of protrusion of the adhesive resin from the fiber sheet. Therefore, the particle size of the BI polyurethane is 8 μm or less. Preferably it is. Therefore, it is preferable to use an emulsion or suspension BI polyurethane. The BI polyurethane may be forcibly dispersed by an emulsifier, or may be a polyurethane having a hydrophilic segment and / or a blocking agent having a hydrophilic group, and may be a non-emulsifier. Those which are not used can be more preferably used since the reduction in water resistance and adhesion due to the emulsifier is smaller.

The blocking agent for the isocyanate group which can be used in the present invention includes sodium acid sulfite, aromatic secondary amine, tertiary alcohol, amide, phenol, lactam, and the like.
Heterocyclic compounds, hydrocyanic acid, sulfites, malonic acid diethyl ester, acetoacetic ester, acetylacetone, etc.,
Heat, pressure, UV, oxygen, ozone, chemicals, microorganisms,
Those that easily dissociate by applying ultrasonic waves, high-energy rays, or the like alone or in combination can be suitably used. Among these, since the adhesive interlining is conventionally adhered to the fabric by heat and pressure, it is a blocking agent that dissociates in the same manner as the conventional method, and an acid sodium sulfite that dissociates easily at a low temperature is particularly preferably used. it can.

The polyurethane of the present invention may be any polyurethane obtained by reacting an isocyanate with a polyester polyol, polyether polyol, acrylic polyol, castor oil derivative or tall oil derivative.

The adhesive provided on the fiber sheet of the adhesive interlining of the present invention contains the above-mentioned adhesive resin and BI polyurethane, and may be in the form of paste or powder. As described above, it is preferable to use an emulsion-like or suspension-like BI polyurethane, and therefore it is more preferable to use a paste-like adhesive. In the case of this paste adhesive, the adhesive resin and BI
In addition to the polyurethane, a thickener, a dispersant, or a BI polyurethane reaction accelerator may be included. This paste-like adhesive can be easily formed only by stirring the adhesive resin and the BI polyurethane, and if necessary, other materials.

When the fiber sheet constituting the adhesive interlining of the present invention has been subjected to the water repellent treatment, the contact between the adhesive and the fiber sheet is larger than that of the adhesive interlining using the non-water repellent fiber sheet. As a result of increasing the corners, that is, the adhesive adheres to the fiber sheet with a smaller contact area, if the same amount of adhesive is applied as before, the amount of adhesive protruding on the fiber sheet increases, so that the adhesive adheres It easily penetrates into the fabric, and the adhesive resin is cross-linked by BI polyurethane, and the interface between the adhesive interlining and the fabric and the cohesive force in the fabric are improved. Adhesive strength is dramatically improved, and on the other hand, even if a smaller amount of adhesive is applied than before, the amount of adhesive protruding on the fiber sheet can be made equal to that of the past, and moreover, the adhesive interlining Interface with dough Since the cohesive force in the fabric is improved, not only can the initial adhesive strength superior to the conventional one, and the adhesive strength after the steam treatment can be secured, but also the excellent effect that the feeling can be improved as compared with the conventional one. Have.
In particular, this effect is remarkable when the adhesive is a paste.

As the water repellent which can be used in the water repellent treatment, for example, there are a silicone resin and a fluorine resin. Among these, silicone resins can be suitably used because they can make the fiber sheet flexible at the same time as water repellency. The degree of the water repellency is set to a value of 60 or more, more preferably 80 or more, in a water repellency test specified in JIS-L-1092 so that the above-mentioned effect is easily generated.

The fiber sheet constituting the adhesive interlining of the present invention includes, for example, a woven fabric, a knitted fabric, and a nonwoven fabric, but when a paste-like adhesive suitable in the present invention is used, the adhesiveness becomes higher. An excellent nonwoven fabric can be suitably used.
Hereinafter, the nonwoven fabric will be briefly described.

As the fibers constituting the nonwoven fabric, for example,
Synthetic fiber consisting of a single resin component such as polyester fiber and nylon fiber, regenerated fiber such as cellulose fiber and polynosic fiber formed by solvent extraction, natural fiber, polyester and nylon, and 6,6 nylon and 6 nylon A composite fiber composed of a plurality of resin components and having shrinkage, heat-fusing properties, splitting properties and the like can be used alone or in combination. Among these, fibers having splitting properties and cellulose fibers formed by the solvent extraction method, the former is split by applying an external force, and the latter is fibrillated, so that the fibers are more easily entangled and have excellent strength. In addition, the resistance to bending and the like is reduced, so that a nonwoven fabric with excellent drapability can be obtained. Further, the nonwoven fabric structure becomes dense, so that it does not come off even when an adhesive is applied. Have.

The fineness of these fibers (in the case of fibers having splitting properties or cellulose fibers formed by a solvent extraction method,
Fineness after division or fibrillation) is 0.001 to 5
It is preferably about denier. If it is 0.001 denier or more, the strength of the nonwoven fabric is not remarkably reduced, and if it is 5 denier or less, the drapability is not impaired. Further, when the fiber length is 1 mm or more, the fibers can be firmly bonded to each other, and a nonwoven fabric in which plastic deformation hardly occurs can be formed.

Using such fibers, a fiber web is formed by a dry method such as a card method or an air-lay method, or a wet method, and then partially or entirely impregnated with a binder, or a fiber constituting the fiber web. Is partially or entirely fused, entangled by a fluid flow such as water, or a combination thereof as appropriate to bond the fiber web to form a nonwoven fabric. In addition, when a fiber web containing splittable fibers or cellulose fibers formed by a solvent extraction method is entangled with a fluid flow, the fibers are split by the action of the fluid flow,
Fibrillation occurs at the same time, and there is an effect that it is not necessary to take another step such as division or fibrillation. Further, a nonwoven fabric and a woven fabric, a knitted fabric, a yarn, or the like may be combined.

The basis weight of the nonwoven fabric or the composite with the nonwoven fabric thus obtained is preferably 10 to 45 g / m ² . If the basis weight is 10 g / m ² or more, plastic deformation is unlikely to occur, and if the basis weight is 45 g / m ² or less, drapeability is not impaired, and more preferably 15 to 40 g / m ^2.
It is.

Next, the above-mentioned adhesive is applied entirely or partially on the fiber sheet. However, as in the latter case, it is possible to provide an adhesive interlining having a better feeling when applied partially. Because it is possible, it is more suitable. If the adhesive is in powder form, it can be scattered, and if it is in paste form, it can be applied using a screen or gravure roll. In any case, so as not to impair the feeling, adhesive weight (solid content) 3 to 30 g / m ^2, more preferably from 5 to 20 g / m ^2, in the case of the latter pasty adhesive Agent density 10
The number is 250 / cm ² , more preferably 30 to 180 / cm ² .

Next, in order to fix the adhesive on the surface of the fiber sheet, heat, pressure, ultraviolet rays, oxygen, ozone, chemicals, microorganisms, ultrasonic waves, high energy rays, etc. are used alone or in combination. Also, the blocking agent of the BI polyurethane is dissociated and a part of the isocyanate groups react, so that the melt viscosity increases and the penetration into the fiber sheet is suppressed. However, if the treatment conditions are too strong, the reaction of the isocyanate groups will proceed too much and it will not be possible to adhere to the fabric. Therefore, it is necessary to appropriately set the treatment conditions depending on the type of the blocking agent. For example, when an adhesive containing a BI polyurethane using a sodium acid sulfite as a blocking agent is fixed by heating, 80 to 80%
The treatment is preferably performed at a temperature of 130 ° C. for 20 to 120 seconds.

Since the garment of the present invention uses the cloth to which the above-mentioned adhesive interlining is adhered, the iron slides well,
Moreover, the adhesive interlining does not peel off when wearing clothes, washing or dry cleaning. When the adhesive interlining of the present invention is adhered to the cloth, the reaction of the isocyanate group proceeds sufficiently,
Heat, pressure, UV, oxygen, ozone, chemicals, microorganisms,
It is preferable that they are used alone or in combination as appropriate, such as ultrasonic waves and high energy rays, and that they are sufficiently bonded.

Since the bonding interlining is conventionally bonded by heat and pressure, when bonding by the same method as in the past, sufficient heat and pressure are applied so that the blocking agent is dissociated. Is preferred. For example, when the blocking agent is sodium acid sulfite, at a temperature of 110 to 150 ° C,
It is preferable to heat-treat for 5 to 60 seconds and pressurize instantaneously at 0.5 to ² kg / cm ² . In addition, in the bonding step of the bonding interlining, even if the cross-linking is not sufficiently performed, usually, after the clothing is formed, the steam processing is performed, so the cross-linking reaction proceeds even by the heat of the steam processing. There is no need to bond well. In this case, the decrease in the adhesive strength due to the deterioration of the adhesive resin after steam is compensated for by the crosslinking, so that the decrease in the adhesive strength of the adhesive is small.

Examples of the present invention will be described below, but the present invention is not limited to the following examples.
