Description

  The present invention relates to a method for producing an adhesive interlining, and an adhesive interlining.

  Adhesive interlining used as clothing material is used to control the formability of clothing, to stabilize the form and prevent it from losing its shape (shape retention), or to improve the ease of sewing. It is used for the purpose. In the adhesive interlining, for example, a thermosetting resin, a thermoplastic resin, or the like is fixed to a surface of a base fabric (fabric) in a dot shape (dot shape). The adhesive interlining is bonded to the outer material and used as a cloth for clothing.

  For example, a sinter type, a powder dot type, or a double dot type is adopted as a method for manufacturing an adhesive interlining. FIG. 4A is a perspective view showing a sinter type adhesive interlining 101. In the sinter type, the adhesive resin powder 108 is fixed to the base cloth 5 by heating after the adhesive resin powder 108 is spread on the base cloth 5.

  FIG. 4B is a cross-sectional view showing a powder dot type adhesive interlining 102. In the powder dot type, the adhesive resin powder 108 is fixed to the base cloth 5 by heating after the adhesive resin powder 108 is thermally transferred onto the base cloth 5.

  FIG. 4C is a cross-sectional view showing a double dot type adhesive interlining 103. In the double dot type, for example, an acrylic resin or a urethane resin is transferred to the base fabric 5 as the lower layer resin layer 107, and after the adhesive resin powder 108 (granular hot melt adhesive) is sprayed thereon, the lower layer is heated. The adhesive resin powder 108 is fixed to the base fabric 5 through the resin layer 107 (see, for example, Patent Documents 1 and 2).

  Sinter-type adhesive interlinings have low adhesive strength, and therefore there is a need for improved adhesive strength. In the case of the sinter type, when the adhesive resin powder is sprayed, dispersion of the spraying condition occurs and the adhesive force is uneven. When manufacturing a sinter-type adhesive interlining, it is necessary to fuse the adhesive resin powder, and the amount of heat applied to the fabric increases, so the fabric is often damaged and there is a limit to the fabric that can be used as a base fabric. .

  In the case of a powder dot type adhesive interlining, the seepage (strike back) of the adhesive resin to the back side of the interlining may occur. In the powder dot type adhesive interlining, since the adhesive interlining is thermally transferred, the processing speed is limited and the manufacturing time cannot be shortened. In addition, since the base fabric is damaged by the heat at the time of thermal transfer, the crimp may be weakened, and the fabric that can be used as the base fabric is limited.

  In the double-dot type adhesive interlining, the adhesive resin may ooze out to the surface side of the surface because the lower layer resin layer is formed thick on the base fabric. For this reason, it is difficult to employ double dot type interlinings for outer fabrics such as thin fabrics. If the size of the dots in the lower resin layer becomes too small, the screen may be clogged, so there is a limit to reducing the diameter of the dots in the lower resin layer.

  The present invention has been made to solve such problems, there is no limit to the fabric of the interlining used, preventing the seeping of the adhesive resin to the surface, the occurrence of strikeback It aims at providing the manufacturing method of the adhesive interlining which can manufacture the adhesive interlining with which quality improvement was aimed at by suppressing this and preventing the fall of a texture.

  In addition, the present invention has been made to solve such problems, and there is no limitation on the fabric of the interlining used, and it is possible to prevent the adhesive resin from seeping out to the surface side, strike back An object of the present invention is to provide an adhesive interlining in which the quality is improved by suppressing the occurrence of cracks and preventing the deterioration of the texture.

  The present invention includes a transfer step of transferring an aqueous liquid having a non-volatile component (A) greater than 0 wt% to 10 wt% or less onto a base cloth in a dot shape, and a thermoplastic resin (B ), A removing step for removing the powder of the thermoplastic resin (B) that has been sprayed in excess of the aqueous liquid transferred onto the base fabric in the form of dots, and an aqueous liquid and a thermoplastic resin.

Provide a method.

  According to such a method for producing an adhesive interlining, an aqueous liquid having a non-volatile component (A) of more than 0 wt% and not more than 10 wt% can be transferred to a base fabric in the form of dots, so that dots can be formed thinly. it can. After spraying the thermoplastic resin (B) powder on the base fabric, the excess sprayed thermoplastic resin (B) powder other than on the aqueous liquid transferred in the form of dots is removed. Resin (B) powder can be uniformly attached. By these, since the thickness of an adhesive interlining can be made thin, the seepage to the surface material side of a thermoplastic resin (B) can be prevented.

  The aqueous liquid contains non-volatile component (A) greater than 0 wt% and not more than 10 wt%, and the non-volatile component (A) remains between the thermoplastic resin (B) powder and the base fabric. Can be suppressed.

  Since the dot-like aqueous liquid is thinly formed on the base fabric, the heat treatment time can be shortened, and damage to the base fabric due to heat can be avoided.

In the method for manufacturing an adhesive interlining, a base fabric having a thickness of 3 to 40 g / m ² can be used, and therefore an adhesive interlining can be manufactured using a thin base fabric.

  The powder of the thermoplastic resin (B) may be 0.5 to 10 μg / dot, and more preferably 0.5 to 2.0 μg / dot. Thereby, the distribution of the powder of the thermoplastic resin (B) can be made uniform.

Mass _{M B} of the powder mass _{M A} and the thermoplastic resin of the non-volatile component (A) (B) ^{_{is, M A ≦ 1g / m 2}} , and may be _{0% <M A / (M} A + M B) ≦ 10% . Thus, non-volatile components of the aqueous solution (A), 1 and powder of the mass M _A of the thermoplastic resin _(B), suitably keeping the M _B, it is possible to reduce the interfacing while ensuring the adhesion.

  In the transfer step, the aqueous liquid is transferred using a rotary screen method, and the viscosity of the aqueous liquid during the transfer is preferably 1,000 to 100,000 cps.

  In the transfer step, the aqueous liquid is transferred using a gravure method, and the viscosity of the aqueous liquid at the time of transfer is preferably 50 to 30,000 cps.

  According to such an adhesive interlining, the thermoplastic resin (B) powder can be uniformly attached to the base fabric through the nonvolatile component (A), and the thickness of the adhesive interlining can be reduced. The seepage of the thermoplastic resin (B) to the surface can be prevented. Since the non-volatile component (A) is interposed between the thermoplastic resin (B) powder and the base fabric, the occurrence of strikeback can be suppressed.

Mass _{M B} of the powder mass _{M A} and the thermoplastic resin of the non-volatile component (A) (B) ^{_{is, M A ≦ 1g / m 2}} , and ₀ <are the _{M A / (M A + M} B) ≦ 10% can non-volatile component (a), and powdered mass M _a of the thermoplastic resin _(B), the M _B properly maintained, decreasing the interfacing while ensuring the adhesion.

  According to the method for producing an adhesive interlining according to the present invention, it is possible to prevent the adhesive resin (thermoplastic resin (B)) from exuding to the surface side, to suppress the occurrence of strikeback, and to prevent the texture from being lowered. By doing so, an adhesive interlining with improved quality can be manufactured.

  Hereinafter, an embodiment of an adhesive interlining of the present invention and a manufacturing method of an adhesive interlining will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same or an equivalent element, and the overlapping description is abbreviate | omitted. The dimensions of the drawings do not necessarily match those described.

  FIG. 1 is an enlarged schematic cross-sectional view showing a clothing fabric provided with an adhesive interlining according to an embodiment of the present invention. FIG. 1 shows a state in which a surface material 2 is bonded to the surface of the adhesive interlining 1. Moreover, depending on the case, the lining 3 is sewn on the back surface of the adhesive interlining 1, and the cloth 4 for clothing is formed. The adhesive interlining 1 includes a base cloth 5 and an adhesive layer portion 6 fixed to the surface of the base cloth 5.

  The base fabric 5 may be any material and fabric structure as long as it has the necessary strength for the interlining. Examples of the base fabric 5 include natural fibers, regenerated fibers, synthetic fibers, and woven and knitted fabrics and nonwoven fabrics made of a mixture thereof. Examples of natural fibers include cotton, hemp, silk, and hair. Examples of regenerated fibers include long fibers and short fibers such as rayon, cupra, and polynosic acetate. Each is used alone as a blended or entangled yarn with natural fiber or recycled fiber. As the non-woven fabric, a fiber-bonded non-woven fabric, an adhesive-bonded non-woven fabric, a hydroentangled non-woven fabric, etc., or a non-woven fabric combined with a filament, net, knitted fabric or woven fabric can be used.

Weight per unit area of the base fabric 5 ^is preferably ^{3g / m 2 ~40g / m 2} . Further ^10g / ^{m 2 ~30g} / m 2 is more preferable. When the weight per unit area of the base fabric 5 is less than 3 g / m ² , the gap between the base fabrics is too large, and it may be difficult to adhere the aqueous liquid to the surface of the base fabric.

  FIG. 2 is an enlarged schematic cross-sectional view showing an adhesive interlining according to an embodiment of the present invention. The adhesive interlining 1 has an adhesive layer portion 6 fixed to the base fabric 5. The adhesive layer portion 6 includes a nonvolatile component layer portion 7 (nonvolatile component (A), first adhesive portion) fixed to the surface of the base fabric 5 and an adhesive resin portion 8 (fixed to the surface of the nonvolatile component layer portion 7 ( Second adhesive portion). In the adhesive resin portion 8, a plurality of powders (8) of the thermoplastic resin (B) are fixed to one dot-like nonvolatile component (7 (A)).

  The non-volatile component layer portion 7 is formed by transferring an aqueous liquid containing the non-volatile component (A) onto the base fabric 5. The aqueous liquid to be transferred contains a non-volatile component (A) that is greater than 0 wt% and less than or equal to 10 wt%. The non-volatile component (A) contained in the aqueous liquid is preferably 5 wt% or less, more preferably 3 wt% or less, and even more preferably 1 wt% or less. Components other than the non-volatile component (A) contained in the aqueous liquid are mainly water.

  Examples of the nonvolatile component (A) include water-soluble acrylic resins, water-soluble urethane resins, and thickeners. Examples of the thickener include a water-soluble acrylic thickener, a water-soluble urethane thickener, a natural product thickener, and a mineral thickener.

  In the adhesive interlining 1, the remaining non-volatile component (A) of the aqueous liquid transferred in a dot shape forms a dot-like non-volatile component layer portion 7. The dot shape refers to a pattern formed from a large number of discontinuous points or small areas on the surface of the base fabric 5. Examples of the shape of the dots in plan view include a circle, an ellipse, and a polygon (for example, a square, a rectangle, a hexagon, and the like).

The number of dots in the nonvolatile component layer portion 7 is, for example, 8 to 800 / cm ² . When the number of dots is less than 8 / cm ² , the adhesive force of the nonvolatile component layer portion 7 is insufficient. When the number of dots exceeds 800 / cm ² , the texture of the outer material 2 becomes hard.

  The outer diameter of the dots of the nonvolatile component layer portion 7 is, for example, 0.01 to 3.0 mm. The outer diameter of the dots of the nonvolatile component layer portion 7 is more preferably 0.05 to 2.0 mm. If the outer diameter of the dots is less than 0.01 mm, the dots become too small and transfer becomes very difficult. When the outer diameter of the dots exceeds 3.0 mm, the dots become too large, and a large number of thermoplastic resin (B) powders, which will be described later, are fixed and formed into large lumps, which causes flickering and bleeding. It should be noted that the glittering means that the adhesive resin (thermoplastic resin (B)) has a shape close to a mirror surface and is visually shining in the adhesive interlining 1 or the cloth for apparel 2 bonded to the adhesive interlining 1. A phenomenon that can be seen.

  The ratio of the area with respect to the base fabric 5 of the non-volatile component layer part 7 is 0.1 to 30%, for example. The ratio of the area of the non-volatile component layer portion 7 to the base fabric 5 is more preferably 0.5 to 15%.

  The adhesive resin portion 8 is formed by spraying a powder of thermoplastic resin (B) on the base fabric 5 to which the aqueous liquid is transferred (details will be described later). Examples of the thermoplastic resin (B) include polyamide, polyester, polyethylene, EVA (ethylene-vinyl acetate copolymer) resin, PVA (polyvinyl alcohol) resin, polyurethane resin, and mixtures thereof. The melting point of the thermoplastic resin (B) is preferably 70 to 150 ° C.

The particle size of the thermoplastic resin powder (B) is preferably, for example, 200 μm or less. Mass _{M B} of the thermoplastic resin powder (B) may be a 0.1～10.0Myug / dot, and more preferably further 0.5 to 2.0 / dot.

In interfacing 1 of the present embodiment, the mass M _B of the powder of the nonvolatile components of the aqueous liquid that has been transferred to the base fabric 5 (A) mass M _A and group thermoplastic resin fixed to the fabric 5 (B) is 0% <M _A / (M _A + M _B ) ≦ 10%.

  Next, a method for producing the adhesive interlining 1 according to the embodiment of the present invention will be described. FIG. 3 is a schematic view showing a method for manufacturing the adhesive interlining 1 according to the embodiment of the present invention. The method of manufacturing the adhesive interlining 1 according to the present embodiment includes a transfer step of transferring the aqueous liquid to the base cloth 5 in the form of dots, and a powder of the thermoplastic resin (B) on the aqueous liquid transferred to the dots. There are provided a spraying step of spraying, a removing step of removing excessively sprayed thermoplastic resin (B) powder, and a heating step of heating the base fabric.

  In the transfer step, the aqueous liquid 71 is attached to the surface of the base cloth 5 in the form of dots using a cylindrical screen 11 that rotates about a predetermined rotation axis. A plurality of through holes for allowing the aqueous liquid 71 to pass therethrough are formed on the peripheral surface of the screen 11 corresponding to the number of dots. The diameter of the through hole corresponds to the size of the dot diameter of the nonvolatile component (A) to be attached to the base cloth 5 and the shape of the dot of the nonvolatile component (A). As described above, the aqueous liquid contains the nonvolatile component (A) greater than 0 wt% and 10 wt% or less.

  A squeegee 12 for supplying an aqueous liquid 71 is provided in the screen 11. The aqueous liquid supplied from the squeegee 12 is pushed out through the through hole of the screen 11 and adheres to the surface of the base fabric 5. The aqueous liquid is transferred in a dot shape to the base cloth 5 that is sandwiched and conveyed between the screen 11 and the back roll 13.

  The transfer method (transfer process) may be a rotary screen method, a gravure method, or other methods. In the case of the rotary screen system, the transferred aqueous liquid has a viscosity of 1,000 to 100,000 cps. In the case of the gravure method, the viscosity of the aqueous liquid to be transferred is 50 to 30,000 cps.

  In the spraying step, the thermoplastic resin (B) powder 81 is attached to the aqueous liquid 71 using the hopper 14 (scatter) for spraying the thermoplastic resin (B) powder 81 (crushed material). It sprays on the surface side of the cloth 5, and the powder 81 of the thermoplastic resin (B) is adhered to the aqueous liquid 71. The powder 81 of the thermoplastic resin (B) is attached to the base fabric 5 through the aqueous liquid 71.

  In the removing step, the excess thermoplastic resin (B) powder 81 dispersed on the surface of the base fabric 5 is shaken off or blown off. Excess thermoplastic resin (B) powder 81 is recovered by using air blow 15 for ejecting air and suction nozzle 16 for sucking excess thermoplastic resin (B) powder 81. The air blown out from the air blow 15 blows off the excess powder 81 of the thermoplastic resin (B) on the surface of the base fabric 5. The blown-off thermoplastic resin (B) powder 81 is sucked and collected by the suction nozzle 16.

  In the removal step, the amount of the thermoplastic resin (B) powder 81 adhering to the aqueous liquid 71 can be controlled by controlling the flow rate of the air flow sprayed onto the base fabric 5. By increasing the flow rate of the air flow, the amount of the thermoplastic resin (B) powder 81 blown off by the air flow can be increased, and the amount of the thermoplastic resin (B) powder 81 adhering to the aqueous liquid 71 can be decreased. it can.

  In the removing step, the powder 81 of the thermoplastic resin (B) not attached to the aqueous liquid 71 is removed in principle. By blowing an air flow, the powder 81 of the thermoplastic resin (B) sprayed on portions other than the dots (aqueous liquid 71) is blown off.

  The spraying method (spreading step) may be a vibration spraying method, or may be a method of transporting and spraying the powder 81 of the thermoplastic resin (B) using the recesses of the engraving roll. By such a spraying step, the thermoplastic resin (B) powder 81 adheres to the wet (wet) dot layer application portion (dot-like aqueous liquid 71).

In the production method of the present embodiment, the mass _{M B} of the powder mass _{M A} and the thermoplastic resin of the non-volatile component (A) (B) is ^{_{M A ≦ 1g / m 2,}} 0 <% M A / (M _A + M _B ) ≦ 10% is preferable.

  In the heating step, the volatile component of the aqueous liquid 71 is evaporated, the nonvolatile component (A) is fixed to the surface of the base fabric 5 to form the nonvolatile component layer portion 7, and the thermoplastic resin (B) is formed on the nonvolatile component (A). The powder 81 is fixed to form the adhesive resin portion 8. In the heating process, the base fabric 5 to which the aqueous liquid 71 and the thermoplastic resin (B) powder 81 are attached is placed in an environment having a temperature of 120 to 180 ° C. for about 10 to 60 seconds. In the heating step, for example, by heating in a hot air drying furnace or the like, the powders of the thermoplastic resin (B) are fused together, and the adhesive is made into a lump to form a double structure layer (nonvolatile component layer portion 7 and adhesive resin portion 8). Form.

  The heating process has, for example, a fixing zone and a heat setting zone. In the fixing zone, heat treatment is performed by a heater 17 such as a hot air circulation type or a far red heater type. In the heat setting zone, hot air (for example, 120 to 180 ° C.) is sprayed by the hot air fan 18 (hot air drying furnace).

  The thermoplastic resin (B) powder 81 adhering to the aqueous liquid 71 before the heating step partially or entirely doubles and adheres to the nonvolatile component layer portion 7 to form the adhesive resin portion 8. The powder 81 of the thermoplastic resin (B) is heated and fixed to the base fabric 5.

  In the transfer process, the spraying process, the removing process, and the heating process, for example, the base cloth 5 is continuously transferred while transporting the base cloth 5 using a transport device having the back roll 13, and the aqueous liquid 71 is transferred and thermoplastic. It is preferable to perform dispersion of the powder 81 of the resin (B), removal of the excess powder 81 of the thermoplastic resin (B), and heat treatment. The conveyance speed of the base fabric 5 may be selected in consideration of the area ratio of the non-volatile component layer portion 7, the molten state of the powder 81 of the thermoplastic resin (B) by heating, and is preferably about 10 to 50 m / min, for example. .

  By performing the manufacturing method as described above, the adhesive interlining 1 according to the embodiment of the present invention can be obtained.

  According to the adhesive interlining 1 according to the embodiment of the present invention, the thermoplastic resin (B) powder (adhesive resin portion 8) is uniformly attached to the base fabric 5 through the nonvolatile component layer portion 7, and the thickness is increased. Can be thinned. Thereby, the seepage of the thermoplastic resin (B) to the surface can be prevented. Since the non-volatile component (A) is interposed between the thermoplastic resin (B) powder and the base fabric 5, the occurrence of strike back can be suppressed.

Bonding the interlining 1, the mass M _B of the powder of the nonvolatile components of the aqueous liquid that has been transferred to the base fabric 5 (A) mass M _A and the thermoplastic resin fixed to the base fabric _{(B), M A ≦ 1g} / Since m ² and 0% <M _A / (M _A + M _B ) ≦ 10%, the mass of the powder of the non-volatile component (A) and the thermoplastic resin (B) is appropriately maintained to ensure the adhesive force. The adhesive interlining can be made thin.

Mass _{M A} of the nonvolatile components of the aqueous liquid that has been transferred to the base fabric. 5 (A) is preferably _{M A} ≦ 1 g / ^{m 2,} more preferably _{M A} ≦ 0.3 g / ^{m 2,} More preferably, M _A ≦ 0.1 g / m ² . The mass M _B of the thermoplastic resin (B) powder fixed to the base fabric 5 is preferably 0% <M _A / (M _A + M _B ) ≦ 10%, and 0% <M _A / (M _A + M _B ) ≦ 5% is more preferable, and 0% <M _A / (M _A + M _B ) ≦ 3% is more preferable.

  According to such a method for manufacturing an adhesive interlining, an aqueous liquid having a non-volatile component (A) of more than 0 wt% and not more than 10 wt% can be transferred to the base fabric 5 in the form of dots. Can be formed thinly. Since the powder 81 of the thermoplastic resin (B) can be removed after the powder 81 of the thermoplastic resin (B) is sprayed onto the aqueous liquid 71 transferred in the form of dots, the sprayed thermoplastic resin can be removed. The powder 81 of (B) can be uniformly attached. By these, since the thickness of the adhesive interlining 1 can be made thin, the seepage to the surface material 2 side of a thermoplastic resin (B) can be prevented.

  The aqueous liquid contains a non-volatile component greater than 0% and 10 wt% or less, and the non-volatile component (A) remains between the powder 81 of the thermoplastic resin (B) and the base fabric 5, thereby suppressing the occurrence of strikeback. can do.

  Since the dot-like aqueous liquid 71 is thinly formed on the base cloth 5, the heat treatment time can be shortened, and damage to the base cloth 5 due to heat can be avoided.
