Description

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

  For example, when fabrics are stacked, moire (interference fringes) may occur. As a technique for suppressing the occurrence of such moire, a technique described in Patent Document 1 is known. In the technique of Patent Document 1, a woven fabric is woven using synthetic fiber false twisted yarns having a total fineness of 22 dtex or less representing both the thickness and the warp and weft. This woven fabric has a structure in which the texture points where the warp yarns are floated on the weft yarns and the texture points where the weft yarns are floated on the warp yarns are arranged randomly and densely.

JP 2010-18908 A

  In the technique described in Patent Document 1, it is necessary to design how the texture points where the warp yarns are arranged and the texture points where the weft yarns are arranged are arranged. There is a risk that it will be time consuming and costly.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a base fabric and an adhesive interlining that can save the trouble of designing the weaving and suppress the occurrence of moire. And

  The present invention is a base fabric in which a relaxation treatment is applied to a woven fabric made of warp and weft, and the woven fabric includes a first crimped yarn and a second crimped crimp made of a plurality of filaments on both the warp and the weft. The first crimped yarn and the second crimped yarn are arranged next to each other, and the second crimped yarn has a single fineness of the first crimped yarn. The base fabric which is 1.3 times or more is provided.

  In this base fabric, in both the warp and the weft, a relaxation treatment is applied to a woven fabric in which the first crimped yarn and the second crimped yarn having different single fineness are arranged so as to be adjacent to each other. Since the single filaments of the first crimped yarn and the second crimped yarn are different from each other, the relaxation treatment causes a difference in the degree of contraction between the first crimped yarn and the second crimped yarn. And since the single fineness of the second crimped yarn is 1.3 times or more than the single fineness of the first crimped yarn, both the warp and the weft have the same length when weaving. A difference in the lengths of the first crimped yarn and the second crimped yarn is clearly produced by the relaxation process between the first crimped yarn and the second crimped yarn. Therefore, the difference in contraction rate between the first crimped yarn and the second crimped yarn can be made suitable, and the regularity of the arrangement of the warp and weft when the base fabric is viewed from the plane can be broken. Thereby, the base fabric which can suppress generation | occurrence | production of a moire by the simple method which does not require the design effort can be implement | achieved.

  As for the warp and the weft, it is preferable that one second crimped yarn is arranged every time one to five first crimped yarns are arranged. In this case, the difference in shrinkage between the first crimped yarn and the second crimped yarn due to the relaxation process becomes suitable, and the regularity of the arrangement of the warp and the weft can be broken.

  The yarn count representing the thickness of the first crimped yarn is preferably equal to or less than the yarn count representing the thickness of the second crimped yarn. Since the thickness of the first crimped yarn having the smaller single fineness is equal to or smaller than the thickness of the second crimped yarn having the larger single fineness, the first crimped yarn and the second crimped yarn The difference between the shrinkage rate and the yarn can be increased.

  In addition, it is preferable that the fabric is subjected to weight reduction processing for reducing the weight of the fabric after the relaxation treatment. In this case, the warp and the weft can be thinned by the weight reduction process, and the frictional resistance at the intersection of the warp and the weft of the fabric can be reduced. Since the intersection between the warp and the weft is easily shifted and the regularity of the arrangement is easily lost, the occurrence of moire can be further suppressed.

  The present invention also provides an adhesive interlining comprising the above-described base fabric and having an adhesive resin attached to the surface of the base fabric.

  According to such an adhesive interlining, the regularity of the arrangement of the warp and weft of the woven fabric can be broken, so that the occurrence of moire can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, while suppressing the increase in manufacturing cost, the effort of the design and adjustment of weaving can be saved, and the base fabric and the adhesive interlining which can suppress generation | occurrence | production of moire can be provided.

It is a schematic sectional drawing which shows the adhesive interlining provided with the base fabric which concerns on embodiment of this invention. It is a top view which shows arrangement | positioning of the warp and weft of the textile fabric used for the base fabric in FIG. It is an organization chart (plain weave) of a base cloth concerning an embodiment of the present invention. It is an organization chart (twill weave) of a base cloth concerning an embodiment of the present invention. It is an organization chart (a satin weave) of the base fabric concerning an embodiment of the present invention.

  Hereinafter, embodiments of the base fabric of the present invention 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.

  A base fabric 1 according to this embodiment shown in FIG. 1 can be used for an adhesive interlining 2, for example. The adhesive interlining 2 includes a base cloth 1 and a resin portion 3 formed on the surface of the base cloth 1. The adhesive interlining 2 is used by being bonded to the clothing fabric 4.

  The base fabric 1 is obtained by subjecting the fabric 5 (see FIG. 2) to a relaxation treatment. The fabric 5 is a fabric woven using warps 51 and wefts 52. Examples of the material of the warp 51 and the weft 52 include synthetic fibers and recycled fibers. Synthetic fibers include nylon, polyester, polyacrylonitrile, polyethylene, polypropylene and the like. Examples of recycled fibers include polynosic, rayon, and cupra.

  The warp 51 and the weft 52 of the woven fabric 5 are composed of crimped yarns that are crimped when placed in water (when moisture is absorbed). Examples of crimped yarns that are crimped in water include false twisted yarns. The false twisted yarn is a processed yarn processed by a false twister. False twisted yarn is the mainstream of crimped yarn and is also called false twisted yarn. The warp 51 and the weft 52 are formed by twisting a plurality of filaments.

  In addition, the woven fabric 5 is arranged so that yarns having different single fineness are adjacent to each other in the warp yarn 51 and the weft yarn 52. The single fineness here is a numerical value indicating the thickness of the filament constituting the yarn. Single fineness means the count of the filament. In the woven fabric 5 of the present embodiment, a crimped yarn 61 having a small single fineness (hereinafter also referred to as “first crimped yarn 61”) and a crimped yarn 62 having a large single fineness (hereinafter referred to as “second crimped yarn 62”). Is also used).

  The single fineness of the first crimped yarn 61 is preferably 0.5 to 1.2 dtex, and the single fineness of the second crimped yarn 62 is preferably 2.0 to 5.0 dtex. The single fineness of the second crimped yarn 62 is preferably 1.3 times or more the single fineness of the first crimped yarn 61. In addition, the yarn count of the first crimped yarn 61 is preferably 7 to 33 dtex, and the yarn count of the second crimped yarn 62 is preferably 11 to 33 dtex. The yarn count here is a numerical value indicating the thickness of the yarn.

  The ratio (B / A) of the yarn count B of the second crimped yarn 62 to the yarn count A of the first crimped yarn 61 is preferably 1 ≦ B / A ≦ 4. That is, the yarn count of the first crimped yarn 61 is preferably equal to or less than the yarn count of the second crimped yarn. The ratio of the number of first crimped yarns 61 to the number of second crimped yarns 62 in the warp 51 is preferably 1: 1 to 5: 1, and may be 1: 1 or 2: 1. More preferred. That is, for the warp 51, it is preferable to use the second crimped yarn 62 at intervals of 1 to 5, and more preferably to use the second crimped yarn 62 at intervals of 1 or 2. Further, the ratio of the number of the first crimped yarns 61 and the number of the second crimped yarns 62 in the weft yarn 52 is preferably 1: 1 to 5: 1, and more preferably 1: 1. That is, the weft yarn 52 preferably uses the second crimped yarn 62 at intervals of 1 to 5, more preferably the second crimped yarn 62 at intervals of one.

  As long as the woven fabric 5 has a necessary strength for the interlining, various woven structures can be applied. Examples of the woven structure of the woven fabric 5 include plain weave, twill weave and satin weave. Here, FIGS. 3 to 5 show examples of woven structure diagrams. FIG. 3 is an example of plain weave. According to the woven structure diagram shown in FIG. 3, the structure point (the square portion painted with diagonal lines with fine pitch) where the warp 51 floats on the weft 52 and the weft 52 floats on the warp 51. The structure points (outlined square portions) organized in this manner are arranged densely.

  FIG. 4 shows an example of twill. Compared with the plain weave, the twill weave shown in FIG. 4 has fewer points where the warp 51 and the weft 52 intersect (hereinafter also referred to as “intersection”) than the plain weave shown in FIG. Therefore, the regularity of the arrangement of the warp 51 and the weft 52 is likely to be broken. FIG. 5 shows an example of satin weave. The satin weave shown in FIG. 5 has fewer intersections between the warp 51 and the weft 52 than the plain weave and the twill weave. Therefore, the regularity of the arrangement of the warp 51 and the weft 52 is more easily broken.

Weight per unit area of the fabric 5 ^is preferably ^{5g / m 2 ~80g / m 2} . It is preferable and more ^{10g / m 2 ~60g / m 2} . When the weight per unit area of the woven fabric 5 is less than 5 g / m ² , the woven fabric itself is too thin or the gap between the yarns becomes large. It can be difficult to adhere.

  The resin portion 3 formed on the surface of the base fabric 1 has a lower layer resin portion 31 fixed to the base fabric 1 and an adhesive resin portion 32 fixed to the lower layer resin portion 31. The lower layer resin portion 31 is formed of the resin R1, and the adhesive resin portion 32 is formed of the resin R2. The lower layer resin portion 31 is for favorably fixing the resin R2 to the base fabric 1.

Examples of the resin R1 include polyurethane / acrylic, polyamide, polyester, polyethylene, EVA-based and PVA-based resins. The resin R1 may be a thermoplastic resin such as a hot melt resin or a curable resin that can be cured by heat or ultraviolet light, but a thermosetting resin that is crosslinked by heat is more preferable. The resin R1 is preferably ^{2g / m 2 ~30g / m 2} .

  For the resin R2 forming the adhesive resin portion 32, a thermoplastic resin that is plasticized by heat, usually called hot melt, and exhibits adhesive ability after cooling is used. The resin R2 is preferably a thermoplastic resin having a melting point of 80 to 140 ° C. Examples of the resin R2 include polyamide, polyurethane, polyester, polypropylene, polyethylene, and a modified ethylene vinyl acetate copolymer.

In forming the adhesive resin 32 resin R2 is ^{2g / m 2 ~20g / m 2} , it is preferable to fix the lower resin portion 31. Incidentally, the sum of resin R1 and resin R2 is preferably ^{2g / m 2 ~35g / m 2} .

  The resin R1 and the resin R2 may contain a polymerization initiator, a crosslinking agent, a pigment, a dye, a drying inhibitor, and other modifiers as necessary.

  Usually, the dot-shaped lower layer resin portion 31 is transferred to the surface of the base fabric 1 using a cylindrical rotary screen that rotates about the rotation axis. A hole having a size corresponding to the diameter of the resin dot to be transferred is formed on the peripheral surface of the rotary screen, and the lower layer resin R1 passes through the hole of the rotary screen and is transferred to the surface of the fabric. .

  Next, the manufacturing method of the base fabric which concerns on embodiment of this invention is demonstrated. First, as described above, the woven fabric 5 is woven using the first crimped yarn 61 and the second crimped yarn 62 for each of the warp yarn 51 and the weft yarn 52 (weaving step). In the weaving step, for example, the first crimped yarn 61 and the second crimped yarn 62 are alternately arranged to weave the fabric 5. The first crimped yarn 61 and the second crimped yarn 62 are arranged so that the single yarns of adjacent yarns are different.

  Next, the relaxation process of relaxing the fabric 5 woven in the weaving process is performed. In the relaxation process, the fabric 5 is relaxed in a liquid, and a process of removing strain generated during processing or expressing bulkiness is performed. Expressing bulkiness means expressing the potential crimpability of false twisted yarns and the like.

  After the relaxation process, a weight reduction process for reducing the weight of the fabric 5 is performed (a weight reduction process). In the weight reduction step, the fabric 5 is subjected to a weight reduction process using an alkaline solution. As the weight reduction treatment, the fabric 5 may be reduced with caustic soda (sodium hydroxide), or the weight reduction treatment may be performed with an alkaline solution with another alkaline substance (for example, calcium hydroxide). You may perform a weight reduction process using chemicals other than. By performing the weight reduction process, the frictional resistance at the intersection of the warp 51 and the weft 52 of the fabric 5 is reduced. As a result, the intersection between the warp yarn 51 and the weft yarn 52 is displaced, so that the regularity of the arrangement of the warp yarn 51 and the weft yarn 52 is easily broken, and the occurrence of moire can be suppressed. The base fabric 1 can be manufactured by performing such a process.

  After the weight loss process, a setting process for stabilizing the shrinkage and shape of the base fabric 1 is performed. In the setting step, a heat setting process for heating the base fabric 1 is performed. In the heat setting process, for example, heating at 140 ° C. to 220 ° C. is performed to fix the density and shrinkage of the base fabric 1. Thereby, the unevenness | corrugation of the surface of the base fabric 1 can be reduced, and the shrinkage | contraction of the base fabric 1 can be stabilized.

  When manufacturing an adhesive interlining using the base fabric 1, an adhesive application process is performed after a setting process. In the adhesive application step, a paste-like lower layer resin (resin R1) is attached to the base cloth 1 in the form of dots, and the resin R2 powder, which is a thermoplastic resin, is sprayed on the surface of the base cloth 1 to which the resin R1 is attached. The resin R2 is attached to the resin R1 and heated to fix the resin R1 to the surface of the base cloth 1 and to fix the resin R2 to the resin R1.

  According to the method for manufacturing the base fabric according to the embodiment of the present invention, the woven fabric 5 in which the first crimped yarn 61 and the second crimped yarn 62 are arranged adjacent to each other in each of the warp yarn 51 and the weft yarn 52. Relax. Thereby, since a difference can be provided in the degree to which the 1st crimped yarn 61 and the 2nd crimped yarn 62 shrink | contract, the uniformity of both the vertical direction of the textile fabric 5 and a horizontal direction will be impaired. Therefore, manufacturing the base fabric 1 capable of suppressing the occurrence of moire by a simple method that does not require a design effort as compared with the case where the density is adjusted or the processing conditions are adjusted as before. Can do.

  Further, by performing the weight reduction process after the relaxation process, the frictional resistance at the intersection of the warp 51 and the weft 52 of the fabric 5 is reduced. Thereby, a shift | offset | difference arises in the intersection of the warp 51 and the weft 52, and generation | occurrence | production of a moire can be suppressed further.

  When the yarn count of the first crimped yarn is A and the yarn count of the second crimped yarn is B, if 1 ≦ B / A ≦ 4, the second crimped yarn is compared with the first crimped yarn. Thus, it is possible to avoid the fabric 5 from becoming too thick and the fabric 5 from becoming too thick, and to suppress the occurrence of moire.

  In the above-described embodiment, the double dot type adhesive interlining 2 has been described. However, the present invention is not limited to this, and the occurrence of moire can be similarly suppressed even in single dot type and powder dot type adhesive interlinings. it can.
