Description

  The present invention relates to an adhesive interlining, a garment fabric, and a garment.

  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. The adhesive interlining is, for example, a lower layer resin made of a thermosetting resin, a thermoplastic resin, or the like fixed to a surface of a base fabric (fabric) in a dot shape (dot shape), and this surface of the lower layer resin is called a hot melt. The adhesive resin is fixed. The adhesive interlining having the lower layer resin and the adhesive resin is bonded to the outer material and used as a clothing fabric.

  The part where the adhesive interlining is used varies depending on the type and design of the clothing, but for example, heavy clothing such as jackets and coats have a lot of load due to human movement, so the interlining is used throughout the body. May be. Also, in order to prevent the clothing from losing its shape due to its own weight, if a single interlining is not sufficient in shape retention, a method of using an extra core that overlaps two interlinings or a technique that uses shoulder pads, etc. Is adopted.

  On the other hand, in order to eliminate the complexity of the additional core method, the adhesive interlining is physically divided into two or more in the warp direction or the weft direction of the base fabric, and the bending rigidity is gradually increased or decreased in each section. An interlining is known (see, for example, Patent Document 1). In the interlining described in Patent Document 1, the bending rigidity is changed by changing the yarn count of each section. Further, in the technique described in Patent Document 1, in a case where a three-layer body is formed by double bonding with a front core (multiple bonding method), an attempt is made to improve followability with respect to a dimensional change of the outer material.

JP-A-2-14002

  In such an adhesive interlining, after securing the adhesion to the outer material, the shape-retaining property is required in the portion corresponding to the predetermined clothing article, and the texture is required in the other portions rather than the shape-retaining property. There is a case (when shape retention is not required so much). For example, there is a case where shape retention is required in the portion corresponding to the chest from the shoulder, and the texture is emphasized in the portion corresponding to the abdomen.

  Although the conventional additional core method achieves the purpose in terms of shape retention, the number of bonded adhesives increases, and various problems occur. That is, if a plurality of interlinings are used, the number of times of bonding increases, resulting in an increase in cost. As the number of pasting increases, the heat history increases and the damage to the outer material increases. Further, when the number of interlinings increases, the weight of the fabric increases and the wearing feeling is impaired. When the number of interlinings increases, the thickness of the fabric increases and the appearance of the clothes may be impaired.

  Moreover, when the prior art described in Patent Document 1 is adopted, the yarn count is changed for each section, so that the changing point of the texture is noticeable and the feeling of wearing the clothes is impaired. In addition, even if the yarn count is changed in an inclined manner in the width direction of the base fabric, it is difficult to stably secure physical properties in the weaving process and the processing process, and there is a problem that the work efficiency is greatly reduced. It is not realistic. For this reason, there is a demand for a technique for suppressing a decrease in work efficiency in the manufacturing process of the adhesive interlining and stably manufacturing the product.

  The present invention has been made in order to solve such a problem, and eliminates the complexity in the bonding process between the outer cover and the adhesive interlining as in the conventional additional core technique, and reduces the wear feeling of the clothes. It is easy to handle while suppressing, and by changing the distribution of resin dots on one piece of interlining, these are changed according to the texture and shape retention required for each part of clothing. An object is to provide an adhesive interlining.

The present invention is an adhesive interlining in which the resin R1 is fixed in a dot shape on the surface of the base fabric, and the occupation ratio S, which is the ratio of the occupied area of the resin R1 per unit area of the base fabric, is 0.5 to 20%. The adhesive interlining has a first region A and a second region B, and the number Na per unit area of the dot-shaped resin R1 existing in the first region A exists in the second region B. There is provided an adhesive interlining which satisfies the following formula (1), which is larger than the number Nb per unit area of the dot-shaped resin R1.

  According to such an adhesive interlining, the number Na per unit area of the dot-shaped resin in the first region A is larger than the number Nb per unit area of the dot-shaped resin in the second region B, The number can be 1.5 or more times the number Nb. Thereby, by changing the number of dots per unit area between the areas of one adhesive interlining, the distribution of the resin dots can be changed, and the shape retention of the adhesive interlining can be changed. it can. In addition, since the shape retaining property can be changed in the adhesive interlining of one base fabric, an adhesive interlining that is easy to manufacture and has good workability is realized while suppressing a decrease in the wearing feeling of the clothing. be able to.

Further, in the adhesive interlining, the first region A and the second region B are separated from each other, the number Na and the number Nb satisfy the following formula (2), and between the first region A and the second region B: In the region adjacent to the first region A, the region on the first region A side is the third region C, and the region on the second region B side is the fourth region D. The dot-shaped resin existing in the third region C The number Nc per unit area of R1 and the number Nd per unit area of the dot-shaped resin R1 present in the fourth region D may be an adhesive core that satisfies the following formula (3).

  That is, the adhesive interlining having this configuration has a first area A and a second area B that are separated from each other on the surface of a single base fabric, and the number Na of the first areas A is the number Nb of the second areas B. 10 times or more. In addition, a third region C on the first region A side and a fourth region D on the second region B side are arranged adjacent to each other between these regions. In this case, the number Nc per unit area of the dot-shaped resin in the third region C is set to a number within 10 times the number Nd per unit area of the dot-shaped resin in the fourth region D. it can. In addition, the ratio (Nc / Nd) of the number of dots in the third region C and the fourth region D adjacent to each other is equal to the ratio of the number of dots in the first region A and the second region B that are separated (Na / Nb). It can be 0.7 times or less.

  It should be noted that there is a horizontal inflection point in the change in the number of dots between the first area A and the second area B, and the first in the area where the number of dots decreases from the second area B side toward the first area A. In the third region C and the fourth region D, (Nc / Nd) can be 1/10 or more, that is, 0.1 or more. Further, it can be set to 1 / 0.7 times or more of the ratio (Nb / Na) of the number of dots in the second area B and the first area A, that is, 1.5 times or more.

  Thereby, when the difference between the number Na and the number Nb is large, the distribution of the resin dots can be gradually changed stepwise or in an inclined manner. Therefore, the texture and shape retention can be greatly changed in the separated areas, and the texture and shape retention can be gradually changed between the areas. In other words, it is possible to provide an adhesive interlining having a high shape-retaining property at a site that requires a high shape-retaining property and an excellent wearing feeling (texture) at other portions. Moreover, it is possible to suppress the occurrence of winding slip when producing the adhesive interlining.

  Here, in the adhesive interlining having the first region A and the second region B that satisfy the above formula (2), any third region C and fourth region D that are adjacent to each other between the regions. It is preferable that the above formula (3) is always satisfied. That is, it is preferable to satisfy the above formula (3) in all the third regions C and the fourth regions D.

Measurement of the number (Na, Nb, Nc, Nd) per unit area of the dot-shaped resin R1 existing in each region is performed by, for example, selecting an arbitrary position in the region and measuring the 25 mm × 25 mm square of the surface of the base fabric Measure for the area within the square. In this case, for example, one set of sides defining a measurement range is parallel to the warp, and the other set of sides is measured for a range in the square parallel to the weft. In addition, the measurement range for measuring the number per unit area may be any position in each region, may have any shape, and the area is not limited. In short, it is only necessary that the “number per unit area” measured in an arbitrary measurement range in each region satisfies a predetermined condition (formulas (1) to (3)). Further, the measurement of the occupation rate and the particle size of the dots, which will be described later, may be performed in the same manner. In the present invention, the number of dots present in each region is the number neglected for dots having a dot area of less than 0.002 mm ² .

Further, the ratio of the occupied area of the resin R1 per unit area of the base fabric in the first region A is defined as the occupation ratio Sa, and the ratio of the occupied area of the resin R1 per unit area of the base fabric in the second region B is occupied. In the case of the rate Sb, the ratio between the occupation rate Sa and the occupation rate Sb can be an adhesive interlining that satisfies the following formula (4).

  When the occupancy ratio of each region is within the range represented by the above formula (4), it is possible to easily realize suitable adhesive force and shape retention as an adhesive core.

  The adhesive interlining is preferably configured such that the first region A and the second region B are separated in the weft direction of the base fabric (that is, the width direction of the base fabric). In the first region A and the second region B that are separated in the weft direction, the distribution of resin dots can be changed to change the shape-retaining property according to the part of the clothing. In addition, it is easier to manufacture an adhesive interlining if a difference is provided in the weft direction than a difference in the distribution of dots in the warp direction.

  The adhesive interlining may have a configuration in which a resin R2, which is a thermoplastic resin having a melting point of 140 ° C. or lower, is fixed to the surface of the resin R1.

  Moreover, this invention provides the cloth for clothing which has said adhesive interlining and the outer fabric bonded together to the said adhesive interlining.

  Since such a cloth for clothing is provided with the above-mentioned adhesive interlining, the distribution of the resin dots can be obtained by changing the number Na and the number Nb of dots in the interlining of one base cloth. It has a changed part, and the shape retention can be changed according to the part of the clothing. Since the shape retention of the adhesive interlining can be changed, it is possible to realize a garment fabric that can be easily manufactured while suppressing a decrease in the wearing feeling of the garment.

  The present invention includes a garment that covers at least a part of a wearer, and the garment is formed using a cloth having the above-described adhesive interlining and a surface bonded to the adhesive interlining. I will provide a.

  Since such garments are provided with the above-mentioned adhesive interlining, the distribution of resin dots can be changed by changing the number Na and the number Nb of dots in the adhesive interlining of one base fabric. The shape retention property can be varied according to each region while suppressing the decrease in wearing feeling.

  According to the present invention, by changing the distribution of the resin dots in the adhesive interlining, it is easy to handle while suppressing a decrease in the wearing feeling of the clothing, and the shape retention is changed according to the portion of the clothing. An adhesive interlining that can be provided can be provided.

Mass per unit area of the base fabric 3 ^is preferably ^{5g / m 2 ~80g / m 2} . When the mass per unit area of the base fabric 3 is less than 5 g / m ² , the gap between the base fabrics is too large, and it may be difficult to attach the resin R1 to the surface of the base fabric.

  The lower layer resin portion 4 made of the resin R1 fixed to the surface of the base fabric 3 is for forming the adhesive resin portion 5 by favorably fixing the resin R2 to the base fabric 3. The resin R1 is a thermosetting resin, a thermosetting resin prepreg, or a thermoplastic resin. As the material of the resin R1, for example, an acrylic or urethane thermoplastic resin can be suitably used. The melting point of the resin R1 before fixing the resin R2 is preferably 100 to 170 ° C.

The occupation ratio S of the resin R1 is an area ratio of the lower layer resin portion 4 (resin R1) per unit area of the base fabric 3 (occupation ratio S = area occupied by the lower layer resin portion 4 / area of the base fabric 3). ). The occupation ratio S is preferably 1 to 15%. Occupancy S is preferably within this range in all regions of adhesive interlining 1. In order to measure the occupation ratio, an arbitrary measurement range may be selected, and the area occupied by the lower layer resin portion 4 in the measurement range may be measured to obtain the occupation ratio.

For example, when winding an adhesive interlining, a shift is likely to occur.

  Next, the manufacturing method of the adhesive interlining which concerns on embodiment of this invention is demonstrated. FIG. 3 is a schematic view showing a method for producing an adhesive interlining according to an embodiment of the present invention. The method for producing the adhesive interlining 1 according to the present embodiment includes a first adhesion step in which the resin R1 is adhered in the form of dots on the surface of the base cloth 3, and a thermoplastic resin on the surface of the base cloth 3 to which the resin R1 is adhered. The resin R2 powder, which is a resin, is sprayed and the resin R2 is adhered to the resin R1, and then the heat treatment is performed to fix the resin R1 to the surface of the base cloth 3, and the resin R2 And a heat fixing step for fixing to the resin R1.

  In the first attaching step, the resin R1 is attached to the surface of the base fabric in the form of dots using a cylindrical screen 6 that rotates about a predetermined rotation axis. On the peripheral surface of the screen 6, a plurality of through holes for allowing the resin R1 to pass therethrough are formed corresponding to the number of dots. The diameter of the through hole corresponds to the size of the dot diameter attached to the base cloth 3.

  In the screen 6, a squeegee 7 for supplying the resin R1 is provided. The resin R <b> 1 supplied from the squeegee 7 is pushed out through the through hole of the screen 6 and adheres to the surface of the base fabric 3. The resin R <b> 1 is transferred to the base fabric 3 being sandwiched between the screen 6 and the back roll 8.

  In the second adhering step, the resin R2 is applied to the surface of the base fabric 3 to which the resin R1 is attached using a hopper 9 (scatter) for applying the resin R2 powder (pulverized product), and the resin R2 Is attached to the resin R1. In the resin R2 powder of this embodiment, the average value of the particle diameter is 50 μm to 200 μm, and the powder having a particle diameter of 80 μm to 160 μm is 90 wt% or more.

  Thereafter, after the second adhesion step, before the heat treatment, it is preferable to shake off or blow off excess resin R2 powder spread on the surface of the base fabric 3. The excess resin R2 is recovered by using the air blow 11 for ejecting air and the suction nozzle 12 for sucking the excess resin R2. The air blown out from the air blow 11 blows off excess resin R2 on the surface of the base fabric 3. The blown-off resin R2 is sucked and collected by the suction nozzle 12.

  In the heat fixing step, the resin R1 is fixed to the surface of the base cloth 3 to form the lower layer resin portion 4, and the resin R2 is fixed to the resin R1 to form the adhesive resin portion 5. In the heat fixing step, the base fabric 3 to which the resin R1 and the resin R2 are attached is placed in an environment having a temperature of 100 to 200 ° C. for about 20 seconds to 3 minutes.

  The heat fixing step has, for example, a fixing zone and a heat setting zone. In the fixing zone, heat treatment is performed by a heater 13 such as a hot air circulation type or a far red heater type. In the heat setting zone, hot air (for example, 120 to 160 ° C.) is sprayed by the hot air blower 14.

  In the heat fixing step, if the resin R1 is a thermosetting resin, it is thermoset or semi-cured, and if the resin R1 is a thermoplastic resin, it is melted and, in some cases, partially crosslinked to form the lower resin part 4 The base fabric 3 is fixed.

  In addition, the resin R2 powder adhered to the resin R1 before the heat fixing step partially or entirely doubles and adheres to the lower resin portion 4 made of the resin R1 to form the adhesive resin portion 5.

  In the first adhering step, the second adhering step, and the heat fixing step, for example, the base cloth 3 is continuously transferred while the base cloth 3 is being transported using a transport device having the back roll 8, and the resin R1 is transferred. Preferably, the resin R2 powder is dispersed and heat-treated. What is necessary is just to select the conveyance speed of the base fabric 3 considering the occupation rate of the lower layer resin part 4, the molten state of resin R1 and resin R2 by heating, etc., and about 10-50 m / min is preferable.

  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, it is possible to change the shape-retaining property according to the region of the clothing by providing the dot distribution in a single interlining. In the adhesive interlining 1, the number Na per unit area of the dots in the first region A31 is larger than the number Nb per unit area of the dots in the second region B32, and a difference of 1.5 times or more is provided. Therefore, in the interlining of one base fabric, it is possible to change the shape retention. Thereby, since it is not necessary to employ | adopt an additional core system like the past, the adhesive interlining 1 which is easy to handle can be implement | achieved, suppressing the fall of the wear feeling of clothes.

  Moreover, since the cloth for clothing which has the adhesive interlining 1 of this embodiment does not need to be used by laminating | stacking and bonding a plurality of interlinings on a surface, it can suppress the increase in manufacturing cost. Moreover, since the adhesion process of a surface material and an adhesive interlining is completed by one time, the damage to a surface material by the heat history increasing can be prevented. Moreover, since the shape retention property can be satisfied by a single interlining, the thickness does not increase and appearance defects can be prevented. Moreover, an increase in weight due to an increase in the number of interlinings can be prevented, and the feeling of wearing is not impaired.

  The clothing which has the adhesive interlining which concerns on embodiment of this invention is equipped with the body which covers at least one part of a wearer. This body is formed using a fabric having the above-described adhesive interlining 1 and a surface bonded to the adhesive interlining 1. Apparel includes jackets and coats. In the apparel according to the present embodiment, for example, the first area A (area where the number of dots is large) of the adhesive interlining 1 is arranged at a position corresponding to the shoulder or the like, and the second area B (area where the number of dots is small). ) Are arranged at corresponding positions such as the abdomen. In some cases, the dots may be arranged in the opposite direction due to the dot occupancy rate.

  According to the apparel of this embodiment, since the distribution of dots is changed in the interlining of one piece of base fabric, it is possible to suppress a decrease in wearing feeling and have a change in shape retention depending on the part. Can be made. Thereby, the increase in cost and the appearance defect and weight increase due to the increase in the interlining can be prevented.

  As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. In the adhesive interlining 1 of the above embodiment, the first region A31 and the second region B32 are separated in the weft direction (X direction), but may be separated in the warp direction (Y direction).

  In addition, the adhesive interlining 1 is configured to include the first region A31, the second region B32, the third region C33, and the fourth region D34, but the two regions of the first region A31 and the second region B32 are included. A dot distribution of the area may be formed. Further, the dot distribution of the third area C33 and the fourth area D34 is the same, the intermediate area M35 is formed, and the dot distribution of the three areas of the first area A31, the second area B32, and the intermediate area M35 is formed. Also good.

  Further, the dot distribution may be uniform within each region, or the dot distribution may vary within the region. Furthermore, an adhesive interlining having an area where the dot distribution is uniform and an area where the dot distribution is changed may be used.

  Further, the adhesive interlining may change in the dot distribution stepwise along the X direction, or may change in an inclined manner (depending on the position in the X direction). Further, for example, there may be a region where the dot distribution does not change at the end in the X direction.

  Furthermore, there is a horizontal inflection point in the change in the number of dots between the regions between the first region A31 and the second region B32 that are separated from each other, and the number of dots from the second region B32 side toward the first region A31. There may be areas where it decreases.

(Example)
EXAMPLES Next, although this invention is demonstrated based on an Example, this invention is not limited by the following Example. FIG. 4 is a plan view illustrating a region of the adhesive interlining according to the first embodiment.

(Base fabric / dress material)
A plain woven polyester fabric (width 120 cm) having a mass of 20 g / m ² was used as the base fabric of the adhesive interlining. A plain weave polyester fabric having a mass of 40 g / m ² was used as the outer material. The bending properties of the outer material were the warp direction (Y direction) 0.0239 (gf · cm ² / cm) and the weft direction (X direction) 0.0200 (gf · cm ² / cm). The shear characteristics of the outer material were 0.45 (gf / cm / deg) in the warp direction and 0.42 (gf / cm / deg) in the weft direction. The bending characteristics and shear characteristics were measured by a Kawabata evaluation system (hereinafter referred to as KES method), which is widely known as an objective measurement method for fabric texture.

As the thermoplastic resin (resin R1), an acrylic ester copolymer emulsion obtained by thickening an acrylic ester copolymer emulsion with an acrylic thickener to a viscosity of 10,000 cps was used.
As the hot melt adhesive (resin R2), a polyamide-based powder having a melting point of 110 ° C. and an average particle diameter of 100 μm was used.

(Production of adhesive interlining and production of clothing fabric)
While transporting the base fabric at 30 m / min, the resin R1 was transferred into dots using a rotary screen. At this time, along the longitudinal direction (rotational axis direction) of the rotary screen, the area is divided into a region A31, a region M35, and a region B32 each having a length (width) of 40 cm. The difference in dot distribution was provided in the order of the region A31, the region M35, and the region B32 from one end in the width direction (X direction). Within each region, the dot distribution of the thermoplastic resin was evenly transferred.

  Thereafter, the hot melt adhesive powder was sprayed and heated to fix the hot melt adhesive to produce an adhesive core (Examples 1 and 2, Reference Example 1). Overlay the outer material on the produced adhesive interlining, pressurize and heat at 130 ° C, 10 seconds, 0.3 MPa with a roller-type press (Asahi Textile Sales JR900S), and bond the outer fabric to the adhesive interlining to create a cloth for clothing Was made.

  In the adhesive interlining, as shown in FIG. 4, a plurality of (three) measurement ranges adjacent in each region (first region A31, intermediate region M35, second region B32) along the weft of the base fabric. Each dot distribution was evaluated. Arbitrary positions are selected in each of the areas 31, 35 and 32, and an area within a square of 25 mm × 25 mm square is set as one measurement range (measurement range (a) 41, measurement range (m) 45, measurement range (b). 42).

Table 1 shows the “number of dots”, “average area of dots per dot”, “total area of dots”, and “occupancy ratio” of the thermoplastic resin (R1) in each of the regions 31, 35, and 32. there were. “The number of dots” and “the average area of dots per dot” were measured using an image measuring device using a microscope. The values shown in Table 1 are average values of three measurement ranges in each of the areas 31, 35, and 32.

  “Total dot area” is the product of “number of dots” and “average area of dots per dot”. “Dot area” is obtained by dividing the total area of dots within a predetermined range (41, 45, 42) by the number of dots. “Occupancy ratio” is the proportion of dots in a predetermined measurement range, and is a value obtained by dividing the total area of dots by the area (25 mm × 25 mm) of the predetermined measurement range.

The bending properties and the shearing properties of the adhesive fabrics of the regions 31, 35, and 32, and the clothing fabric in which the outer fabric was bonded to the adhesive fabric were measured by the KES method.
Table 2 shows the bending characteristics of the adhesive fabric of each of the regions 31, 35, and 32 and the clothing fabric in which the outer fabric is bonded to the adhesive interlining.

なお、上記の表１〜３の各領域３１，３５，３２の評価値は、複数の測定範囲４１，４５，４２の値の平均値であるが、各領域内において複数の測定範囲間の値の差は無視できる程度であった。 Table 3 shows the shear characteristics of the adhesive fabric of each of the regions 31, 35, and 32 and the clothing fabric in which the outer fabric is bonded to the adhesive interlining.

In addition, although the evaluation value of each area | region 31,35,32 of said Table 1-3 is an average value of the value of several measurement range 41,45,42, it is the value between several measurement ranges in each area | region. The difference was negligible.

Further, the adhesion characteristics in each of the regions 31, 35 and 32 of the clothing fabric were measured in accordance with the peel strength measurement method of JIS-L-1086 “Adhesive bond test method”. The adhesive properties of the garment fabric were as shown in Table 4.

(Evaluation of adhesive interlining)
The larger the bending characteristics and shear characteristics, the higher the shape retention, and the smaller the values, the better the texture. The bending characteristics and the shear characteristics evaluated the shape retention and texture. In both Examples 1 and 2 and Reference Example 1, it was possible to obtain adhesive interlinings having different bending characteristics and shearing characteristics for each region, and having different textures and shape retention properties for each region. In each region, the adhesive properties were in a range that had no practical problems. In the production of the adhesive interlining, it could be produced under substantially the same conditions as the adhesive interlining having the same dot distribution (number of dots, dot area) as the intermediate region M35 over the entire surface of the base fabric.
