Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to an interlining. More specifically, the interlining consisting of a woven or knitted fabric mainly composed of polyester synthetic fiber multifilament yarn spun at a spinning speed of 7,000 m / min or more,
The present invention relates to an interlining material having extremely excellent dimensional stability and at the same time having a soft texture rich in flexibility.

<Prior Art and Problems Thereof> Polyester synthetic fibers are widely used for clothing and materials because they have excellent physical properties and chemical properties.

Conventionally, polyester synthetic fibers have been spun at a spinning speed of 2000 m / min or less, but the yarn obtained by this spinning has high elongation and low strength, and is not suitable for practical use. Therefore, it is customary to further draw the filament yarn so as to impart appropriate mechanical properties such as elongation and strength without causing a trouble in a subsequent step and to use it for actual use. Also in the interlining field, the interlining in woven and knitted fabrics has been put to practical use by taking advantage of the characteristics of polyester synthetic fibers, especially the feature of dimensional stability.

However, conventional interlinings using polyester fibers have an excellent dimensional stability, but have a drawback that they are too stiff, that is, too hard, and are currently in difficulty in softening their texture. Therefore, as a measure for softening, fine denier, roughening, texture examination flexibility, knitting, weaving with other materials,
Various studies have been conducted on methods such as post-processing softening, but none have been found to be sufficiently satisfactory. In other words, as measures against fine denier, coarser density, and flexibility of design, the number of yarn breakage during weaving and knitting, the increase of misalignment of texture, and the poor handling of post-processing Not only will the quality deteriorate, but productivity will also be hindered. or,
When a woven or knitted fabric for these measures is used as an adhesive interlining, the voids between the yarns of the woven or knitted fabric are large, so that the resin comes out when the resin is attached, making it difficult to attach an appropriate amount In addition, the shape of the adhered resin becomes non-uniform, a satisfactory product cannot be obtained, and a problem such as the resin falling off on the interlining side (resin back) occurs even when the resin is adhered to the outer material. On the other hand, when combined with a softening material, there remains concern about poor dimensional stability,
There is a problem with post-processing measures, such as limited flexibility. At present, there is no polyester synthetic fiber woven or knitted interlining material that satisfies both the dimensional stability and the soft texture with high flexibility.

Especially in recent years, the garment materials have become more and more used mainly for women's garments and tend to be softer, thinner, and lighter weight. The characteristics of wear are no longer a special function, but are being demanded as general functions. In such a situation, the required performance of the interlining material suitable for these outer materials becomes severe, and in particular, the dimensional stability against heat of the iron, the press machine and the like as well as the dimensional stability due to washing are sufficiently satisfied, and There is a growing need for an interlining material that has a soft and soft texture that does not impair the texture of the outer material, but the interlining material using conventional woven or knitted polyester synthetic fibers is sufficiently satisfactory. Not taken.

<Means for Solving Problems> In view of such a current situation, the inventors of the present invention have conducted intensive studies to eliminate the defects of the interlining under the present conditions, and as a result, the spinning speed is 7,000 m / min or more. Polyester synthetic fiber Multi-filament A study focusing on the use of woven and knitted fabrics as the interlining material has shown that it is not only excellent in dimensional stability such as heat shrinkage, hot water shrinkage and washing shrinkage, but also highly flexible. We have completed the interlining with a soft texture.

The present invention provides an interlining using a woven or knitted fabric mainly composed of polyester synthetic fiber multifilament yarn spun at a speed of 7,000 m / min or more.

A typical polyester fiber in the present invention consists essentially of polyethylene terephthalate, which is obtained by a known polymerization method. Additives usually used for polyester, such as matting agents, stabilizers, UV absorbers, An antistatic agent or the like may be included. Further, the degree of polymerization is not particularly limited as long as it is within the range for ordinary fiber formation. Further, a copolymer with another component may be used within a range not impairing the object of the present invention.

The present invention uses polyester fibers spun at a spinning speed of 7,000 m / min or more. As a typical example thereof, Japanese Patent Laid-Open No. 57-
There are 121613 etc.

A high-speed spun fiber obtained by spinning a polyester molten polymer at a speed of 7,000 m / min or more becomes a flexible filament yarn while maintaining excellent shrinkage characteristics. It is considered that the reason is that the high-speed spinning advances the orientation of the crystal part, but does not advance the orientation of the amorphous part. Further, in the high-speed spun fiber, at a spinning speed of less than 7,000 m / min, the mechanical properties of the filament yarn such as high elongation, modulus, dimensional stability and the like are not satisfactory for the purpose of the present invention.

The single yarn denier of the polyester synthetic fiber multifilament yarn used in the present invention is 0.1d to 5d, and the constituent denier is
It is preferable to use the one of 10d to 100d. If the denier of the single yarn is less than 0.1 d, the yarn quality such as single yarn breakage and fluffing is greatly deteriorated, and the yarn breakage in weaving and knitting and the occurrence of fluff tend to occur. On the other hand, if it exceeds 5d, the hardness of the filament yarn itself increases, and there is a tendency that satisfactory flexibility cannot be obtained. If the composition is less than 10 denier, not only the overall strength of the interlining material will be insufficient, but also the strength and durability such as wearing and washing tend to be poor. Also, if it exceeds 100 d, the rigidity of the yarn and the thickness of the interlining will increase and it will be difficult to obtain the desired soft texture, and the suitability for the outer material and the use will tend to be limited. This does not apply to conformity with. The woven or knitted fabric used as the interlining is not particularly limited in its structure, and in the case of a woven fabric, a hand weave, a twill weave, a satin weave, a kalami weave, etc. which are used for a usual interlining can be applied, but a plain weave and a kalami weave are It is more preferable that the ground can be thinned. In the case of knitted fabric, tricot knitted fabric can be applied to half, reverse half, quince cord, satin, etc.
In addition, the weft insertion tricot can of course be applied to the weft knitting.

On the other hand, the density of the density, the presence or absence of twist processing, the presence or absence of chemical processing, etc. are not particularly limited, for example,
If you add physical processing such as raising these woven and knitted fabrics,
More flexibility can be promoted.

The interlining of the woven or knitted fabric is applicable to both non-adhesive interlining and adhesive interlining. Particularly in the adhesive interlining, synthetic resin adhesives such as polyamide-based synthetic resin adhesives, polyester-based, polyethylene-based, and polyvinyl chloride-based adhesives can be appropriately selected and used, and the adhered state is also particularly limited. Although not a thing, it is preferable to stick in a dot form from the viewpoint of adhesiveness, washing durability and the like.
