Field of the Invention The present invention relates to a breast interlining having good resilience, firmness and firmness and good shape retention, and a method for producing the same. In particular, the present invention relates to a breast interlining suitable for suits, coats, jackets, and the like, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, a breast interlining for clothing has been formed by laminating a relatively thick fabric such as a woven fabric or a non-woven fabric made of natural fibers or chemical fibers, or a multilayer thereof in order to form and hold a silhouette of the garment. Have been used. In addition, the hair core (wool,
Human hair, yak, camel, horse hair, etc.) have been preferably applied. However, these are thick and heavy, and their colors are limited to animal hair color or gray or black, and have a drawback that they are difficult to harmonize with other members.

[0003] In the conventional interlining for clothes, it is insufficient to form and hold the silhouette of the clothes when only the textile fabric is used, and the performance of firmness and stiffness is supplemented by resin processing or the like. Therefore, the rigidity (one characteristic of firmness and stiffness) is significantly reduced by washing, especially with water washing, and there is a problem that the form and texture of clothes are significantly changed. There was no other way to wash. However, environmental issues have become increasingly important internationally, and dry cleaning with petroleum-based and chlorine-based chemicals is being abolished. ing.

Further, in recent years, it has become common sense to use a thin adhesive interlining on the back surface of the outer material of clothes (especially suits). For example, polyester fiber false twisted yarn) fabric is becoming mainstream. However, conventional breast-filled fabrics using a hair core cause a catching phenomenon called a zipper phenomenon with this synthetic fiber woven fabric, and this has an adverse effect on the silhouette formation of clothes and wearing comfort, and should be solved. It is an important issue.

X-ray generator; X-ray source manufactured by Rigaku Denki Co., Ltd .: CuKα ray (using Ni filter) Curved crystal monochromator (use of graphite) Output: 50 KV 200 mA Goniometer; slit diameter manufactured by Rigaku Denki Co., Ltd. 1 ° -0.15mm-1 ° Detector: Scintillation counter Counting and recording device; RAD-B scan system manufactured by Rigaku Corporation; 2θ / θ: continuous scan Measurement range: 2θ = 5 to 140 ° Sampling: 0. 02 ° Scanning speed: 3 ° / min The present invention relates to a composite yarn comprising at least the two components of the A and B yarns, such as a twisted yarn, a ply-twisted yarn, a aligned yarn, a blended yarn, a loop-processed yarn, and an interlaced yarn. In which the performance of the interlining of the present invention is exhibited. As a preferred specific example, a polyester multifilament of 5 denier or more is used as the A yarn,
/ M or less, preferably 200 T / m or less, more preferably 150 T / m or less, and most preferably 120 T / M or less. A synergistic effect of high resilience of the yarn is obtained, and this is a preferable method for increasing resilience, firmness and stiffness.

The method for preferably producing the breast interlining of the present invention will be described. First, a fabric in which a composite yarn including at least a highly oriented undrawn polyester yarn is arranged is woven and knitted, and a heat shrinkage treatment of a shrinkage rate of 1 to 30% and / or a heat treatment of 120 ° C or more is performed using this fabric. Is achieved. The above-mentioned highly oriented undrawn polyester yarn includes what is usually called polyester POY, and a polyester yarn obtained at a take-up speed of 2500 to 3500 m / min is preferably applied. This highly oriented undrawn polyester yarn and at least another type of yarn (A yarn)
Is made as a composite yarn, and the temperature is 70 ° C. or more, preferably 8
With a dry heat of 0 ° C. or more, more preferably 100 ° C. or more, and most preferably 120 ° C. or more, the shrinkage in the vertical and / or horizontal direction is 1 to 30%, preferably 5 to 20%.
%, More preferably 6 to 15%, most preferably 7 to
It can be shrunk by 12% to produce the interlining of the present invention.

In this processing, in addition to shrinkage, heat treatment is performed by dry heat or wet heat of 120 ° C. or more to crystallize the highly oriented undrawn polyester yarn in a state where the stress received during melt spinning is sufficiently relaxed. And the above-mentioned specific structure is achieved. In order to convert a highly oriented undrawn polyester yarn into a B yarn, the restraint due to the composite yarn form with the A yarn brings a tension state to the highly oriented undrawn polyester yarn when the fabric shrinks, and this state causes the change to the B yarn. Make it effective. That is, the B yarn can be obtained by shrinking at a shrinkage ratio of 1 to 30%. However, if the shrinkage ratio is less than 1%, the above-mentioned stress cannot be sufficiently relieved and the yarn does not become a B yarn. %, Wrinkles due to shrinkage occur, making it impossible to process. Further, it is preferable that the highly oriented undrawn polyester yarn is spontaneously elongated in the process of changing to the B yarn. Heat treatment temperature is 12
Although the purpose can be achieved at 0 ° C. or higher, it is preferably 140 ° C. or higher, more preferably 160 ° C. or higher. The higher the processing temperature, the shorter the performance can be exhibited. Performing the heat treatment at the same time as the shrinkage is a preferable means, and performing the heat treatment at the same time as the dyeing is a more preferable means.

As a preferred specific example, there is a method in which the cloth is subjected to a shrinkage treatment at a dry heat of 70 ° C. or more and then dyed at 110 ° C. or more using a dye having at least a disperse dye.

By such dyeing, all kinds of colors can be colored again and vividly. Conventional breast interlining is limited to gray or black because the color of the raw material is dark or the color of the raw material is dark even when dyed. For this reason, combinations of other members with colors or materials have naturally been limited. In particular, in the case of a combination with a thin material or an open-faced outer material and / or lining, selection of the material of the outer material and / or the lining is limited because the color of the inner lining used for the inside affects the appearance. The chest interlining of the present invention can be colored in any color obtained from the three primary color dyes, that is, full color. It is also possible to make the color much more vivid and deeper than the hair core. This can solve the problem of the combination with other members limited in the hair core, which is a great effect of the present invention.

By such a treatment, the highly oriented undrawn polyester yarn is changed into a special fine structure to exhibit favorable resilience, and it is possible to obtain a chestlined fabric which is hard to wrinkle.
Also, it has anisotropy in resilience and stiffness by using different yarns (single denier, yarn denier) for the warp and weft yarns of the woven fabric or using only one composite yarn including highly oriented undrawn polyester yarn. It can be a chest interlining. Regarding this anisotropy, the transverse softness is preferably 20 to 300 mg, more preferably 50 to 200 mg, still more preferably 60 to 120 mg, and most preferably 65 to 200 mg.
１００100 mg, and the softness in the transverse direction / the softness in the vertical direction is preferably 2 to 30, more preferably 3 to 30 mg.
-20, more preferably 4-10, most preferably 5
~ 8 to achieve this. It is preferable to arrange the composite yarn including the B yarn on the weft yarn. This performance is particularly important in the case of a chest padding.

In addition, one of the notable performances of the present invention is that
Of course, there is no problem with performing resin processing, but it is necessary to have sufficient resilience, firmness, and firmness without using resin processing, which means that the resilience and rigidity due to washing, especially water washing, are small. The dimensional change is small, and the reduction rate in the lateral softness is 20% or less, preferably 15% or less, more preferably 10% or less by the washing described below. The dimensional change is 1.5% or less in shrinkage, preferably 1.0 or less, more preferably 0.8% or less. Sufficient resilience, firmness, and stiffness without resin processing.

As described above, the fact that washing with water is practically possible means that the conventional clothing breast-lining fabric made of only a fiber fabric is insufficient to form and hold the silhouette of the clothing, Processing, etc., supplements the performance of firmness and stiffness, so the resilience and rigidity (one characteristic representing firmness and stiffness) are significantly reduced by washing, especially with water washing, and the form and texture of clothes change significantly, and conventional suits For example, there was only a method of washing with dry cleaning, which has a relatively small decrease in rigidity.In recent years, however, environmental issues have become increasingly important internationally, and dry cleaning with petroleum and chlorine chemicals has been abolished. Therefore, in this regard, the chest interlining of the present invention having sufficient resilience, firmness and firmness without using resin processing is extremely significant. Furthermore, the conventional breast interlining had poor moisture permeability because the surface was coated by resin processing, but the breast interlining of the present invention needs to be subjected to resin processing to compensate for tension and stiffness Because it is not, it has excellent moisture permeability.

Another notable performance is that a fastener phenomenon is unlikely to occur on a synthetic fiber bonding interlining. In the conventional hair core, since the thick and thick yarn end of animal hair is exposed on the surface of the woven fabric, it is entangled with the single yarn of the synthetic yarn bonded to the interlining, causing a snag called the fastener phenomenon, and Comfort and shape retention were greatly impaired. In recent years, as the adhesive interlining for clothes, a synthetic fiber adhesive interlining has become the mainstream, and it is of great significance that the chest interlining of the present invention has no problem.

There are no particular limitations on the weave structure, and plain weave, oblique weave,
Tissues such as satin weave and mosaic weave are preferably applied. In addition, in such a woven structure, imparting large anisotropy with rebound and rigidity in the horizontal direction, or misalignment resistance,
From the viewpoint of imparting elasticity, as the warp yarn, use a false twisted yarn of synthetic fibers such as nylon or polyester, an interlaced yarn, a bulky yarn represented by an indentation yarn, and a composite yarn having a B yarn as a weft yarn. It is preferably used.
Further, it is preferable to use a spun yarn or a blended yarn of a synthetic fiber and / or a natural fiber as the warp yarn, and to use a processed yarn in which the untwisted portion and the untwisted portion of the synthetic fiber are mixed in the warp yarn. It is more preferable because it is difficult to fray.

The organization of the knitted fabric is not particularly limited, and is published by Kinno Silk Tokusha (74, Hirorobu-cho, Kanazawa-shi), published by Masao Terasaki, "Technique of Knitting" (published on July 1, 1972). The mesh edition described on page 91, published by the Textile Research Society Publishing Office (1-17 Nishitakaai-cho, Higashisumiyoshi-ku, Osaka) Author: Tsunehiko Okamoto “New knitting studies” (published February 1, 1967)
Russell lace described on pages 272 to 287 is preferably applied. As a specific organization name, among tulle, turtle shell, chicory mesh, chikara turtle shell, scare net, sand fly net, etc., those which meet the requirements of the present invention can be preferably applied. In particular, in a tricot weft insertion structure, it is a preferable method to apply a composite yarn having a B yarn to the weft insertion yarn.

The breast interlining of the present invention is a suit for men and women,
It is preferably applied as an interlining for clothing such as coats, uniforms and working wear. In particular, it can be preferably applied as a base or basketball core of a chest interlining such as a suit or a coat, and can be preferably applied to a lapel core.

The breast interlining according to the present invention includes a breast augmentation and a front core in industry terms (these are also collectively referred to as “made core”). Breast augmentation refers to the chest interlining in the upper part of the chest (with or without lapel core), and the front core is the chest interlining up to the hem (with or without lapel) There is).

Further, the chest interlining of the present invention has good firmness and firmness, so that the interlining of clothing such as men's and women's suits, coats, uniforms and working wear, the interlining of hats, inside belts, tie cores, It is also preferably applied to collar cores, cufflinks, plackets and the like.

FIG. 2 shows a preferred example of the structure of the breast augmentation for enhancing the effect of the breast interlining according to the present invention. Reference numeral 4 is a base core, 5 is a felt core, and 6 is a basketball core. The use of the breast interlining of the present invention in this base core portion, in addition to silhouette formation and its shape retention, resilience, firmness, dimensional stability, heat retention,
It is preferable because it can exhibit excellent performance in washing resistance. In addition, it is preferable to apply the present invention to a basket core, and to apply both the base core and the basket core.

The method of measuring the physical properties of the interlining of the present invention is as follows. 1) Bending resistance: It is measured by flexural resilience test method A (Gurley method) specified in JIS-L-1018.
It is a value measured by using a Gurley tester by taking a test piece 1.5 inches long and 1.0 inches wide in the vertical and horizontal directions. 2) Washing test: Washing is performed in accordance with JIS-L-0844 A-2 method. 3) Rebound: A square sample (10 cm × 10 cm) was prepared, grasped firmly with a hand and released, and its recovery was qualitatively determined. 4) Fastener resistance: An ordinary polyester false-twisted adhesive interlining and the surface of the test fabric are brought into contact with each other and rubbed to check for any snagging. 5) Moisture permeability: One drop of water is dropped on the surface of the fabric, and the degree of penetration is examined.

[0050]

The present invention will be described in more detail with reference to the following examples. Example 1 75 denier as a warp yarn, a polyester false twisted yarn of 36 filaments, 255 deniers of B yarn as weft yarn, polyester POY of 30 filaments (take-up speed of 3000 m / min), and 300 denier of drawn polyester yarn of 10 yarns. Using a twisted yarn having a number of twists of 100 T / m with the filament, a woven fabric having a plain weave, a vertical density of 108 yarns / inch, and a horizontal density of 40 yarns / inch was woven.

The greige was passed through a pin tenter both in the vertical and horizontal directions with a small tension load, treated at 180 ° C. for 30 seconds, and shrunk by 8% in the width direction. Then 130 ° C
With a disperse dye for 30 minutes using a liquid jet dyeing machine.

As shown in Table 1, the obtained woven fabric had a transverse softness of 72 mg, a ratio of transverse softness / vertical softness of 5.5, and had a good transverse tension. Met. Further, the basis weight was 191 g / m ² . When a washing test was carried out by the above-described method, the bending resistance was hardly reduced and the washing shrinkage was extremely small. The fastener phenomenon with the polyester false twisted yarn bonding interlining did not occur. When a drop of water dropped on the interlining surface, it immediately penetrated.

At this time, the apparent Young's modulus in the load elongation curve of the yarn B was 76 kgf / mm ² , and the initial stress was 0.1 kg / mm ² .
It was 71 g / d, and the initial elongation was 15%. All satisfied the characteristics of the present invention. The birefringence was 67 × 10 ⁻³ , the degree of amorphous orientation was 0.213, and the amorphous density was 1.333 g / cm ³ .

When the suit was used as the base of the breast-enhancing core of the men's suit, the form of the suit was firm, the wrinkles did not easily move, and the shape retention was good. It matched well with the blue fabric used for the lining. Even when ironing was performed at 160 ° C., no ironing was found on the outer material. Further, in the work of cutting and stacking 20 interlinings, the work was easily performed without any cloth slip (cutting slip). Comparative Example 1 150 denier drawn polyester yarn as a warp yarn, 48
Polyester drawn yarn 150 as filament or weft yarn
Denier, 48 filaments and drawn polyester yarn 30
A 0-denier, 10-filament twisted yarn was used to weave a woven fabric (raw machine) having a vertical density of 48 threads / inch and a horizontal density of 56 threads / inch.

This green machine was subjected to dry heat treatment at 180 ° C. for 3 minutes in a width using a pin tenter. Subsequently, liquid-flow dyeing was performed at 130 ° C. for 30 minutes in the same manner as in the example.

The obtained dough had a clearly lower bristles than the examples, and the value of width bristles / length bristles was also 1.8.
And the width was insufficient. In addition, wrinkles were easily formed and shape retention was insufficient.

At this time, the birefringence of the drawn polyester yarn (150 denier, 48 filaments) was 140 × 10 ^−3.
And the degree of amorphous orientation was 0.547, and the amorphous density was 1.308 g / cm ³ . In the load elongation curve, the apparent Young's modulus is 832 kgf / mm ² ,
The initial stress was 2.6 g / d, and the initial elongation was 2%. Comparative Example 2 Conventional hair core (vertical density 66 pieces / inch, horizontal density 5
(3 pieces / inch), the characteristics were measured with the same items as in the examples. As a result, the bristles were at a high level as shown in Table 1, but the transverse bristles were significantly reduced by washing with water. The shrinkage during washing is as large as 2.0% in the horizontal direction. Also, the fastener resistance between the polyester false twisted yarn and the adhesive interlining was extremely poor. When a drop of water dropped on the surface of the interlining, the waterdrop remained as it was and permeated a while later.
