Abstract

PURPOSE:To provide an adhesive interlining which is made of tricot cloth from warp and weft of finely spun-twisted union yarns, thus gives tailored clothes looking better. CONSTITUTION:Roves of acrylic fiber are twisted with nylon 6 false-twisted yarns on the front roller in the fine spinning frame to give finely spun-twisted union yarns. These yarns are used as warp and/or weft to weave tricot cloth and the cloth is preset, dyed and finish set, gigged, finally scattered with a polyamide-based low-melting resin powder in dots to give this adhesive interlining.

FIELD OF THE INVENTION The present invention relates to an adhesive interlining.

[0002]

2. Description of the Related Art Adhesive interlinings, especially adhesive interlinings consisting of normal tricots and weft insertion tricots, are thin and have excellent followability with the surface material. Although it has been used extensively, recent market needs call for an adhesive interlining material that is even more excellent in tailoring and appearance.

[0003] That is, high-grade expansion (hereinafter referred to as HE) due to the high quality of products and the appearance of soft suits.
With the emergence of woven fabrics having a large behavior (hereinafter, woven fabrics having a high HE value), an adhesive interlining material adapted to this has been demanded. The size of the woven fabric changes according to the change of the moisture content, and generally, the woven fabric shrinks when it absorbs moisture and expands and is dried. This phenomenon is called HE. From the IWS method (a dimension (L1) immediately after immersion in 70 ° C. hot water for 30 minutes and a dimension (L2) after drying at 80 ° C. for 4 hours), which is one of the methods for measuring HE behavior, (L1-L2) / L2 × 100 % = HE value), the HE value of a typical worsted fabric is 2 to 4% for polar, 4 to 6% for tropical and saxony, 6 to 8% for amundsen and gabardine.

DISCLOSURE OF THE INVENTION The present invention provides an adhesive interlining material that meets such needs.

[0005]

The present invention is an adhesive interlining comprising a warp insertion and / or weft insertion tricot,
In the adhesive interlining, wherein the inserted warp and / or weft is a finely spun and twisted yarn. The adhesive interlining of the present invention is
In particular, it is useful when used as a front core of a surface fabric having an HE value of 4% or more, and a product having extremely excellent tailoring and appearance can be obtained.

In the present invention, the spun and twisted yarn refers to a silospan composed of so-called short fibers and a silofil composed of short fibers and multifilament yarns. The short fibers and multifilament yarn materials used are cotton,
Natural fibers such as wool, hemp, silk, cupra, viscose rayon, polynosic rayon (especially average degree of polymerization of 500 to
600 is preferred. ) Etc., regenerated cellulosic fibers, such as LYOCELL; for example, Journal of the Textile Society of Japan (Fiber and Industry) Vol. 48, No. 11 (1992) P-584.
~ P. Corresponding to the product name TENCEL manufactured by Courtles, Inc. described in 591. ), Acetate, polyamides, polyesters, acrylics (including polyacrylonitrile and copolymers containing 40% by weight or more of polyacrylonitrile), synthetic fibers such as modified fibers having modified pill resistance, etc. A combination of one or more elastic fibers such as polyurethane can be used.

The fiber length may be short cotton, 2 inches, 3 inches, or worsted, and may be non-shrinkable or shrinkable cotton. The single yarn denier is 0.1 to 5.0 denier, preferably 0.4.
~ 2.0 denier is good because it gives a soft texture. In particular, in order to achieve the object of the present invention, silofil is preferable, and so-called Woolly processed yarn having crimp is finely spun and twisted.

There are no particular restrictions on the count or twist coefficient of the finely spun twisted yarn. For example, the count is 1/30 to 1/20 in metric count.
0 and the twist coefficient may be appropriately selected within the range of 40 to 100. Such a finely spun twisted yarn is used as a warp and / or a weft to knit a warp insertion and / or weft insertion tricot. You may use together in the range of 50% or less.

The spun yarn may be a so-called composite spun yarn such as a ring spun yarn, an open-end spun yarn, or a core spun yarn. The single yarn denier of the fibers constituting the spun yarn is 0.1 to 4 denier, preferably 0.5 to 3 denier, and the count is metric 40 to 80, preferably 50 to 70. Further, as the bulky textured yarn, false twisted textured yarn such as drawn false twisted (POY-DFT) yarn of semi-drawn yarn (POY), known bulky textured yarn such as fluid jet textured yarn, false twist textured and fluid jet. There are composite processed yarns that combine processing.

The single yarn denier is 0.1 to 4 denier, preferably 0.5 to 3 denier, and the total denier is 3.
0 to 80 denier, preferably 40 to 70 denier. Further, 1 to 3 spun yarns and high-loft processed yarns may be alternately used. The number of warp threads and weft threads to be inserted may be appropriately selected as desired. For example, about 1 to 3 warp threads to be inserted may be inserted into adjacent needle loop rows, or the thread may be appropriately removed. Further, the warp inserted as exemplified in JP-A-56-139546 may be inserted so that the warp floats up and down. Furthermore, the warp to be inserted may be either warp insertion (0-0 / 0-0) or weft insertion (for example, 0-0 / 1-1).
~ 0-0 / 6-6) may be sufficient.

The weft yarns are preferably about 30 to 60 threads / inch. The fibers and the structure constituting the ground structure of the warp insertion and / or weft insertion tricot are not particularly limited, and conventionally known ones can be used. For example, the fibers include synthetic fibers such as polyester and nylon,
Particularly, a yarn spun at high speed at a winding speed of 4000 m / min or more, preferably 5000 m / min or more has a soft texture and is preferable, and for example, spinning-drawing-winding is performed in a series of steps at a winding speed of 4000 m / min or more. Spin draw take-up thread to be carried out, 4000 m / min or more, preferably 5000
There is a spin take-up yarn that is spun at high speed at a winding speed of at least m / min.

In particular, the initial modulus of the fiber is 210-35.

[0018]

Example 1 When spinning 2 inches of a 1.5 denier acrylic fiber, 30 d / 10 of a spinning flotton roll was used.
Finely interlaced with a nylon 66 multifilament false twisted textured yarn of f, and spun at a count of 1/48 and a twist number of 380 T / M.
The weft-inserted tricot was knitted by using the finely spun twisted yarn as the weft.

20 d / 7 f nylon 66 multifilament yarn was used for the ground structure, and the warp insertion tricot was knitted by a 24 GG weft insertion tricot machine. (Weft density 51 threads / inch). Organization is front; 0-1 / 1-0,
Back: Knitted with 0-1 / 3-2. Then, preset-dyeing-finishing set-cloth raising is carried out by a conventional method, and powdery polyamide low melting point resin is added at 20 points / in.
The adhesive interlining was obtained by applying in a dod shape of ch × 20 points / inch. (Adhesion amount: 8 g / m ² ) This adhesive interlining is used for the front core, and wool gabardine is used (wool worsted yarn 72 count twin yarn, basis weight 80 g / m ² ,
A HE value of 7%) was adhered with a normal specification and a tailored appearance was sensory evaluated.

As a comparative example, the weft inserted is 1/60 Nm
An adhesive interlining material was obtained and evaluated in the same manner as in Example 1 except that the acrylic spun yarn of was used. The sample of Example 1 was excellent in tailoring appearance, but the sample of Comparative Example was inferior in tailoring appearance as compared with Example 1.
