Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven fabric having stretchability and soft texture suitable for interlining use and improved adhesiveness to a surface material, and more specifically, to a woven fabric in boiling water. The present invention relates to a fabric for interlining, which is provided with a conjugate filament capable of developing crimp and forming an alternate twisted yarn shape portion.

[0002]

2. Description of the Related Art Interlinings are in great demand for women's clothing and men's clothing. The characteristics required for the interlining are stretchability, soft feeling and adhesion to the outer material,
Conventionally, a false twisted yarn of polyester has been often used (for example, JP-A-62-97937).

However, the false twisted yarn has a drawback in that the adhesive performance cannot be sufficiently exhibited when it is adhered to the surface material.

That is, in the false twisted yarn, since the single fibers are opened by crimping, the adhesive permeates into the gaps between the single fibers, resulting in insufficient adhesiveness.

On the other hand, when the number of twists is increased in order to improve the adhesiveness, there is a problem that the texture of the woven fabric is roughly hardened.

[0006]

The object of the present invention is to solve the problems of the prior art described above, to have good stretchability and soft texture, and to improve the adhesiveness with the outer material. The purpose is to provide a textile.

[0007]

Means for Solving the Problems As a result of intensive studies conducted by the present inventors in order to achieve the above object, when forming an alternate twisted yarn-shaped portion using a conjugate filament capable of expressing a three-dimensional crimp. , It was found that the desired fabric was obtained.

Thus, according to the present invention, it is possible to form a three-dimensional crimp in boiling water without forming a mechanical crimping process on at least one of the warp yarn and the weft yarn to form an alternate twisted yarn shaped portion. An interlining fabric woven by arranging conjugate filaments, wherein the conjugate filament has 10 or more alternating twisted yarn shaped portions, and the interlining fabric with improved adhesion is characterized. Will be provided.

The present invention will be described in detail below. The conjugate filament used in the present invention is not particularly limited as long as it is a conjugate filament capable of expressing a three-dimensional crimp in boiling water without forming false twisting and forming an alternate twisted yarn shape portion. However, from the viewpoint of chlorine disinfection resistance and heat resistance, polyester-based conjugate filaments are preferable.

As the above-mentioned conjugate filament, a conjugate filament in which two kinds of components having polybutylene terephthalate and polyethylene terephthalate as main constituents are spun into a side-by-side type or an eccentric sheath core type, or an intrinsic viscosity is respectively An example is a conjugate filament in which two different types of polyethylene terephthalate are composite-spun in a side-by-side type or an eccentric sheath core type.

Particularly preferred is a conjugate filament in which two kinds of components each having polybutylene terephthalate and polyethylene terephthalate as main constituents are composite-spun in a side-by-side type.

[0012] The above-mentioned conjugate filament is placed on at least one of the warp and the weft in a state of being untwisted or given a sweet twist of 300 T / m or less, and any woven fabric,
After being woven into a woven fabric having a flat structure, crimping is preferably caused by heat history such as scouring, presetting, dyeing or final setting to form an alternate twisted yarn shaped portion.

Alternatively, the yarn may be crimped in the state of a yarn and disposed on at least one of the warp yarns and the weft yarns after forming the alternate twisted yarn shape portion, and may be woven into any woven fabric.

In order to achieve the object of the present invention sufficiently,
It is preferable to stabilize the form by tension heat treatment with a preset after forming crimps in the scouring step after weaving to form the alternate twisted yarn shape part.

It is necessary that the conjugate filament constituting the obtained woven fabric has 10 or more alternating twisted yarn shaped portions as shown in FIG. 1 per 1 m (the S direction and the Z direction are counted as one). .

If the number of the alternately twisted yarn-shaped portions is less than 10 / m, the single fibers are opened and the adhesive performance is deteriorated, which is not preferable. On the other hand, since the appearance of the woven fabric is deteriorated even if the number of the alternately twisted yarn-shaped portions is too large, it is preferable to stop it at about 5000 yarns / m or less. The most preferable number of alternating twisted yarn shaped parts is 20 to
It is 2000 pieces / m.

The number of the alternately twisted yarn-shaped portions may be appropriately adjusted according to the stretchability and the feel of the desired woven fabric.
As shown in Fig. 2, when a fabric with a large number of alternating twisted yarn shaped portions is used, a woven fabric having a high stretchability and a thick feeling, and as shown in FIG. A rich fabric is obtained.

The number of alternately twisted yarn-shaped portions can be adjusted by changing the spinning conditions or the drawing conditions of the conjugate filament. For example, under the same spinning conditions, the lower the draw ratio, the greater the number of alternating twisted yarn shaped portions.

When weaving the conjugate filament, it may be woven with natural fibers such as cotton, regenerated fibers such as rayon, and other synthetic fibers as long as the object of the present invention is not impaired.

The woven fabric thus obtained has good stretchability and soft hand, and when used as an interlining, the adhesiveness to the outer fabric becomes very good.

That is, when adhering the interlining material, first, a powdery resin such as copolyamide, ethylene-vinyl acetate copolymer, or polyethylene is sprayed as an adhesive on the surface of the gravure roll having many fine holes. After that, the excess resin is removed, and then the woven fabric heated to about 130 ° C. is brought into contact with the roll to apply the resin accumulated in the holes on the woven fabric while melting.

At this time, in the conventional interlining using the false twisted textured yarn, the yarn constituting the woven fabric is opened by crimping, so that when the adhesive 3 is applied to the interlining 1 as shown in FIG. However, the adhesive 3 oozes into the gaps between the single fibers, and a sufficient adhesive force cannot be imparted.

On the other hand, in order to prevent the permeation of the adhesive by the twisted yarn, the number of twists of 500 to 600 T / m is required, so that the texture of the woven fabric becomes hard.

On the other hand, in the woven fabric of the present invention, since the yarns constituting the woven fabric have the alternately twisted yarn-shaped portions, the single fibers are bundled, and the seepage of the adhesive 3 as shown in FIG. Since it hardly occurs, the interlining 1 and the outer material 2 are firmly bonded.

In particular, when bonding the interlining material as described above,
Since the adhesive is applied only to a part of the woven fabric and the unevenness of the surface of the woven fabric is large, it is important to surely bond the part to which the adhesive is applied to improve the adhesiveness.

[0026]

In the present invention, the core having improved adhesiveness to the outer material while maintaining the soft texture by utilizing the alternate twisted yarn shape portion formed by the expression of the three-dimensional crimp of the conjugate filament. It is possible to obtain a ground fabric.

That is, since the alternating twisted yarn-shaped portion bundles the monofilaments and behaves as if they were twisted, the adhesive does not seep into the gaps between the monofilaments when the adhesive is applied to the fabric. In addition to sufficiently exhibiting the performance, since it is not substantially twisted, it is possible to maintain the stretchability due to crimping and the soft feeling.

On the other hand, when crimping is applied by false twisting or the like, opening of the single fibers occurs, the adhesive permeates into the gaps between the single fibers, and the adhesiveness becomes poor. On the other hand, in order to prevent the bleeding of the adhesive by the twisted yarn, it is necessary to increase the number of twists, which not only impairs the stretchability of the woven fabric but also cannot maintain the soft feeling.

The present invention will be described in more detail below with reference to examples. The characteristics in the examples are measured by the following methods.

(1) Number of alternating twisted yarn shaped parts 1/30 g / in a conjugate filament having a length of 1 m
The load of d was suspended, and marks were made 10 cm above and below the center of the filament, and the number of alternating twisted filaments existing between the 20 cm long marks was read using a stereomicroscope. The measurement was performed 5 times, and the average value was shown.

(2) Stretchability of the woven fabric A sensory evaluation was conducted by 5 experts on the easiness of stretching of the woven fabric in the warp and weft directions, the strength of the recovery force, the settling, etc. It was evaluated on a four-grade scale.

(3) Adhesiveness of woven fabric A gravure roll having a large number of fine holes is used to apply a copolyamide resin adhesive to the woven fabric in spots, and then the woven fabric and a polyester multifilament plain fabric for ladies' blouses. (Warp density 45 / cm, weft density 45 / c
m, basis weight 70 g / m ² ) at 150 ° C., 3.5 kg / c
Adhesion was performed with a press roller under the condition of m ² .

The woven fabric was cut into a length of 15 cm and a weft of 2.5 cm to obtain a sample for measuring adhesiveness, the sample was peeled from the end by 5 cm, and mounted on a constant-speed extension type tensile tester to perform a T-type peel test. The dynamic peeling force (g) was measured (the peeling speed was 1
5 cm / min).

For the dynamic peeling force, the change in peeling force during the peeling of the sample by 5 cm was recorded on the chart, and the average value of the peeling force was read from the chart.

[0035]

[Example] Using a composite spinning machine, polybutylene terephthalate having an intrinsic viscosity of 0.87 and polyethylene terephthalate having an intrinsic viscosity of 0.47 were spun at a ratio of 1: 1 as a side-by-side type conjugate filament, and a speed of 17 was obtained.
After winding at 50 m / min, it was subsequently heat-stretched by 2.5 times to obtain a conjugate filament of 50 denier / 24 filament.

The conjugate filament is used as a warp and a weft without twisting, and has a warp density of 145 yarns / 3.72 cm,
It was woven into a plain weave having a weft density of 98 pieces / 3.72 cm.

Next, the plain fabric is scoured at 100 ° C.,
After drying, after heat setting at 180 ° C. for 45 seconds at an elongation rate of 10% with respect to the width of the raw fabric to obtain a woven fabric having stretchability,
Dyeing and finishing were performed by a conventional method.

The conjugate filaments constituting the woven fabric had 500 / m alternating twisted yarn shaped portions.

The woven fabric had good stretchability and soft hand, and had a dynamic peeling force of 1000 g, which showed good adhesion.

[0040]

COMPARATIVE EXAMPLE 1 The procedure of Example 1 was repeated, except that a conventional polyester false twisted yarn was used in place of the conjugate filament.

The woven fabric thus obtained had a dynamic peeling force of 500 g and was inferior in adhesiveness.

[0042]
