付与した布帛が提供されている。(Prior Art) High-density fabrics using synthetic fiber multifilament yarns are woven at high density using a weaving technique using nylon multifilament yarns, and have been widely used in down-proofing applications. However, in recent years, with the diversification of market needs and the trend toward luxury, products with high sensitivity and functionality have been required. High-density fabrics using synthetic fiber multifilament yarns and JP-A-59-204
As shown in Publication No. 941 and Japanese Patent Application Laid-Open No. 60-39438, a high-density woven fabric is made using a blend of multifilament yarns of high shrinkage components and low shrinkage components of microfibers, and is treated with water repellent treatment. Fabrics have been provided that are made waterproof, moisture permeable, and water repellent.

ていた。(Problem to be solved by the invention) These fabrics have waterproof and moisture permeable functions by arranging the number of fibers per unit area to the maximum in high-density fabrics and reducing the space between fibers to the micron level. is given. Therefore, in the structure of the woven fabric, the fiber density is increased with the fibers aligned as parallel as possible, giving it a slimy feel unique to ultra-fine synthetic fibers, and also giving it a more natural appearance than spun yarn woven fabrics. It had the disadvantage of being inferior in feel.

、緯糸使いに限定されているのが現状であった。On the other hand, synthetic fiber multifilament yarns have been studied in terms of yarn processing technology in order to mimic the texture and appearance of spun yarn fabrics as much as possible. Among them, fabrics using processed yarns obtained by fluid turbulence treatment have been relatively used in recent years because they can obtain spun yarn-like fabrics due to the effects of loops and cruzi, and have been relatively used in recent years. The passability of the processing process is poor, and there is a limit to the use of warp yarns, and the current situation is that the use of weft yarns is limited.

The present invention aims to provide a spun-like high-density fabric having the following characteristics.

A synthetic fiber multifilament yarn with a flat cross-section is used for the other weft (or warp), and the total cover factor of the warp and weft must be 1800 to 3500. It is made of spun-like high-density fabric.

る。In other words, the presence of loops and curls on the surface of the woven fabric of the interwoven multifilament yarn, which is a synthetic multifilament yarn with open loops and closed loops, gives it the texture and appearance of a spun yarn woven fabric. is necessary. There is no big difference whether the above-mentioned interlaced mixed fiber yarn is used in the warp or weft of the fabric. However, if the degree of open loops or closed loops of the interlaced yarn is low, the yarn-like texture and appearance will naturally be poor, and if the degree is high, the weaving process will be difficult to pass through. In particular, there are limitations when using it for warp yarns, and there are general restrictions in high-density weaving.

性が与えられる。Therefore, in the present invention, a latent loop yarn is used as the loop yarn for the warp. The latent loop yarn is preferably a composite yarn with a core-sheath structure for high-density fabrics, and the single yarn denier of the synthetic fiber multifilament yarn used on the 8th side is large, and the synthetic fiber multifilament yarn used on the fine side is suitable for use in high-density textiles. It is best to use yarn with a small single yarn denier. High-density woven fabrics have a large binding force on the threads, so they have high rigidity and a hard texture. Therefore, in order to eliminate these problems,
It is preferable to use ultrafine threads of 0.05 to 1.3 d on the fine side. It is also preferred to use 1-15d on the 8 side, which gives volume and resilience to the fabric.
ここで潜在ループヤーンについて説明する。Here, the latent loop yarn will be explained.
第１図は、本発明に適用する潜在ループヤーンの製造方
法の一例を示す概略図である。FIG. 1 is a schematic diagram showing an example of a method for manufacturing a latent loop yarn applied to the present invention.
第１図に示すように、芯糸のパッケージ１より解舒され
た糸２は第１の供給ローラ３を介して圧空乱流域を形成
する加工装置４に供給される。As shown in FIG. 1, the yarn 2 unwound from the core yarn package 1 is supplied via a first supply roller 3 to a processing device 4 that forms a compressed air turbulence region.
一方、鞘糸のパッケージ５より供給された糸６は第２の
供給ローラ７を介して加工装置４に供給される。これら

に供給することもできる。On the other hand, the yarn 6 supplied from the sheath yarn package 5 is supplied to the processing device 4 via the second supply roller 7. These threads 2, 6 are fed simultaneously to the processing device 4 via suitable guides 8, 9. In addition, the processing device 4 is directly connected to the guide 8.
It can also be supplied to

は緊張される。Both yarns 2 and 6 that have passed through the compressed air turbulence area generated in the processing device 4 become a loop yarn 10, pass through a first take-up roller 11 and a second take-up roller 12, and are further passed through a take-up device 13. and is wound up into a package 14. Note that the yarn is tensioned between the first take-off roller 11 and the second take-off roller 12.

ループやクルジの発生を妨げないので好ましい。この緊
張は小さいとループやクルジの消去効果は小さいし、大
きすぎると圧空乱流域で形成されたループヤーンの微細
ループまでも著しく消去してしまうので好ましくない。This tension is preferable because it is effective in erasing large loops and curls in the loop yarn, and does not prevent the formation of loops and curls that become apparent during heat treatment. If this tension is too small, the effect of eliminating loops and cruzi will be small, and if it is too large, even the minute loops of the loop yarn formed in the pressure air turbulence area will be significantly eliminated, which is not preferable.
ループの消去は、肉眼ではほとんど糸表面にループが存
在することが見えない程度（拡大鏡や顕微鏡では微細な
ループが存在することが解る）とすることが好ましい。It is preferable to eliminate loops to such an extent that the presence of loops on the thread surface is hardly visible to the naked eye (the presence of minute loops can be seen with a magnifying glass or microscope).
上記の潜在ループヤーンの製造方法は、次のような条件
でなされることが好ましい。The method for producing the latent loop yarn described above is preferably carried out under the following conditions.
芯糸に沸騰水収縮率が１０％以上で１、単繊維繊度が１
〜１５ｄのマルチフィラメント糸を用い、鞘糸に芯糸と
の沸騰水収縮率の差が少なくとも５％ある単繊維繊度０
．０５〜１．３ｄのマルチフィラメント糸を用いる。1 if the core yarn has a boiling water shrinkage rate of 10% or more, and the single fiber fineness is 1
~15d multifilament yarn is used, the sheath yarn has a boiling water shrinkage rate difference of at least 5% from the core yarn, and the single fiber fineness is 0.
．． A multifilament yarn of 0.05 to 1.3 d is used.

ーンを同一の引取ローうによって引取る。These yarns are fed from individual supply rollers to a processing device (compressed air supply rate 80 to 12 ON//min) that forms a compressed air turbulence region at different overfeed rates, and are discharged from the processing device, entangled and mixed. The fiber-treated latent loop yarn is taken up by the same taking-off row.
ここでいうオーバーフィード率とは、供給ローラの表面
速度をＶｌとし、引取ローラの表面速度をＶ２としたと
き、フィード率をＦ（％）とすると、
Ｆ（％）＝ （（Ｖｌ −Ｖ２ ＞／Ｖ２ ）ｘｌＯＯ
の値が（＋）となった場合にオーバーフィード率という
。The overfeed rate here means that when the surface speed of the supply roller is Vl, the surface speed of the take-up roller is V2, and the feed rate is F (%), F (%) = ((Vl - V2 > /V2)xlOO
When the value of is (+), it is called the overfeed rate.
そして、芯糸のオーバーフィード率αを２〜１５％、鞘
糸のオーバーフィード率βを５〜３０％、さらに両者の
差β−αを３〜１５％とするのが良い。It is preferable that the overfeed rate α of the core yarn is 2 to 15%, the overfeed rate β of the sheath yarn is 5 to 30%, and the difference β-α between the two is 3 to 15%.
この条件は小さなループ、クルジを圧空乱流域で多く作
るのに適した領域で必る。This condition is necessary in a region suitable for creating many small loops and cruzi in the pressure air turbulence region.
更に好ましい条件としては、第１引取ローラから引き出
された糸を第２の引取りローラにより、前記芯糸のオー
バーフィード率αに対し、０．４α〜０．８αのアンダ
ーフィード率で連続的に緊張せしめつつ巻き取ることで
ある。More preferably, the yarn pulled out from the first take-up roller is continuously fed by a second take-up roller at an underfeed rate of 0.4α to 0.8α relative to the overfeed rate α of the core yarn. It's about winding it up while being nervous.

せることができるものである。The latent loop yarn obtained by the above method is a differentially contracted interlaced mixed synthetic fiber multifilament yarn having fine loops and cruzi on the surface of the yarn, and by heat treatment under no tension, the number of the fine loops, and can be increased in size.
上記の微細なループは、下記に定義するループ△が３０

とができるのである。The use of the above-mentioned latent loop yarns in the warp of textiles enables the weaving of high-density textiles, which was not possible with conventional taslan-based loop yarns. This means that the density can also be increased. By using a synthetic m-fiber multifilament yarn with a flat cross-section for the weft, waterproofness and moisture permeability can be improved compared to those with a round cross-section or other cross-sections.

発明では、該開ループ、閉ループが織物の表面に存在す
るため、柔らげられ、問題とはならない。Since the threads of the multi-filament 1 with a flat cross-section have a property of being arranged almost exactly in a certain direction in the fabric,
Reduce the gap between adjacent threads. In addition, woven fabrics made of 100% flat cross-section multifilament yarn have problems with their flat texture and glare due to specular reflection from the surface, but in the present invention, since the open loops and closed loops are present on the surface of the woven fabric, soft This is not a problem.

風合や外観を低下させるので好ましくない。As shown in FIG. 2, the flatness of the flat cross section is expressed as b/a, where the long length is a and the short length is b in the cross section. The flatness of the multifilament yarn with a flat cross section used in the present invention is 2.0 to 6.
Preferably, it is 0. If the flatness is less than 2.0, the waterproof and windproof properties due to the flatness will be reduced, and if it exceeds 6°0, the gloss will increase and the texture and appearance of the warp threads will deteriorate. So I don't like it.

密度織物が１昇られる。On the other hand, the same result can be obtained by using a synthetic fiber multifilament yarn with a flat cross-section in the warp of the fabric and an interlaced latent loop yarn consisting of a synthetic fiber multifilament yarn with a mixture of intermediate loops and closed loops in the weft. High-density fabrics with the effect of

３０重量％が沸騰水収縮率が１〜１５％の低収縮成分で
あり、さらに、マルチフィラメント糸全体としての沸騰
水収縮率は８〜２７％でおることが好ましい。In this case, it is preferable that the composition of the synthetic fiber multifilament yarn with a flat cross section used for the warp is a mixed fiber yarn of a high shrinkage component and a low shrinkage component. The multifilament yarn constituting the mixed fiber yarn is composed of a high shrinkage component with a boiling water shrinkage rate of 7 to 30%, with a weight of 30 to 70%.
It is preferable that 30% by weight is a low shrinkage component having a boiling water shrinkage rate of 1 to 15%, and that the boiling water shrinkage rate of the multifilament yarn as a whole is 8 to 27%.

ある。Multificimen 1 - If the boiling water shrinkage rate of the entire yarn is small, the so-called multifilament itself will have a strong texture, and the spun yarn-like texture and appearance of the interlaced mixed yarn with loops and closed loops between the wefts will not be utilized. At the same time, there is no improvement in the weft density due to yarn shrinkage during the dyeing process, making it difficult to maintain the function as a high-density fabric. Further, the flatness of the multifilament yarn with a flat cross-section used for the warp is preferably smaller than that of the weft, and a range of 2.0 to 4.5 is usually suitable. If it is larger than 4.5, the gloss will be strong and it will be difficult to take advantage of the spun yarn-like texture and appearance of the weft.
