（イ）産業上の利用分野
本発明は、結合剤を含有せず且つ形態安定性及び風合に
優れたしぼ調率織布に関し、特にタオルや肌着等の用途
に適したしぼ調率織布に関するものである。Detailed description of the invention (a) Industrial application field The present invention relates to a grain-controlled woven fabric that does not contain a binder and has excellent shape stability and texture, particularly for use in towels, underwear, etc. The present invention relates to a suitable grained woven fabric.
（ロ）従来の技術及び発明が解決しようとする問題点
不織布は、織物や編物と異なり、繊維を紡績及び編織す

適するものではなかった。(b) Problems to be solved by conventional technology and inventions Unlike woven or knitted fabrics, nonwoven fabrics can be obtained without spinning, knitting or weaving fibers, so they can be manufactured at low cost and used for various purposes. There is. However, it is inferior to textiles in terms of texture, and is therefore not suitable for use as clothing or cloth personal crystals.
そこで、従来より不織布の表面に多数の畝を形成させ、
しぼ調率織布とし風合の改善を図っている。このしぼ調

せしめた後、潜在感熱収縮性繊維を収縮させ非収縮性繊
維を撓ませて、ウェブ表面に多数の畝を形成させる。そ
の後、結合剤溶液を完全に乾燥させてしぼ調率織布を得
るというものである。Therefore, conventionally, many ridges are formed on the surface of nonwoven fabric.
The texture is improved by using a grain-controlled woven fabric. The method for manufacturing this grained woven fabric is as follows. First, latent heat-sensitive shrinkable fibers and non-shrinkable fibers are mixed to form a web, and a binder solution is applied to the web. Next, the binder solution is brought into a semi-dry state to temporarily bond the constituent fibers in the web, and then the latent heat-sensitive shrinkable fibers are shrunk and the non-shrinkable fibers are bent to form a large number of ridges on the web surface. Thereafter, the binder solution is completely dried to obtain a grained woven fabric.
しかしながら、この結合剤を含有したしぼ調率織布は全
体に結合剤が固着しているため、柔軟性及び手触りの点
で硬さが残っており、十分な風合の改善は行われていな
い。また、構成繊維間が結合剤による結合であるため不
織布の強度が低い。However, because the binder is fixed throughout the grained woven fabric containing this binder, it remains hard in terms of flexibility and feel, and the texture has not been sufficiently improved. . Furthermore, since the constituent fibers are bonded by a binder, the strength of the nonwoven fabric is low.
従って、このような不織布は簡易手拭き等の限られた用
途に用いられるのみで、衣料品やタオル等の布製身回品
として用いることはできなかった。Therefore, such nonwoven fabrics can only be used for limited purposes such as simple hand towels, and cannot be used as clothing, towels, or other fabric personal items.
そこで、本発明者はこの点を改良すべく鋭意検討した結

とに成功し、本発明に至ったものである。Therefore, the inventor of the present invention made extensive studies to improve this point, and as a result, succeeded in obtaining a highly strong wrinkled pulley woven fabric without using a binder, leading to the present invention.

優れたしぼ調車織布に関するものである。(c) Means and action for solving the problem, that is, the present invention is characterized by 5 to 90% by weight of heat-sensitive shrinkable fibers and 10% by weight of non-shrinkable fibers.
~95% by weight of a binder-free nonwoven fabric, wherein the heat-sensitive shrinkable fibers and the non-shrinkable fibers are closely entangled with each other by high-pressure columnar flow, and the heat-sensitive shrinkable fibers are tightly entangled with each other by a high-pressure columnar flow. This invention relates to a wrinkled pulley woven fabric with excellent shape stability, characterized in that the non-shrinkable fibers are deflected by contraction of the fibers, and a large number of random ridges are formed on the surface of the nonwoven fabric. .
本発明で用いる感熱収縮性繊維とは、熱を与えることに
より収縮（本発明においては捲縮を含む）を発現する繊
維である。このような潜在的に収縮性を有する繊維は、
例えば、紡糸中に高度な延伸を施すことによって作成す
ることができる。The heat-sensitive shrinkable fiber used in the present invention is a fiber that shrinks (including crimp in the present invention) by applying heat. Such potentially contractile fibers are
For example, it can be created by applying a high degree of stretching during spinning.
また、収縮率の異なる二成分を別個のノズル孔より溶融

与えることにより一方の成分のみが収縮を起こすため、
捲縮を発現する繊維である。Alternatively, it may be a composite fiber (side-by-side type composite fiber) in which two components having different shrinkage rates are melt-spun through separate nozzle holes and then bonded together. When heat is applied to this composite fiber, only one component contracts, so
It is a fiber that exhibits crimp.
本発明で用いる非収縮性繊維とは、前記の感熱収縮性繊
維が収縮を発現する温度では収縮を起こさない繊維のこ
とである。The non-shrinkable fibers used in the present invention are fibers that do not shrink at the temperature at which the heat-sensitive shrinkable fibers described above contract.

。The grained pulley woven fabric according to the present invention has heat-sensitive shrinkable fibers of 5 to 90%.
% by weight and 10-95% by weight of non-shrinkable fibers. If the heat-sensitive shrinkable fiber is less than 5% by weight, the overall shrinkage will be low (and it is not possible to bend the non-shrinkable fibers sufficiently in manufacturing, so it is not preferable. Exceeding this is not preferable because the amount of non-shrinkable fibers becomes relatively small and the amount of deflection of the non-shrinkable fibers decreases, making it difficult to form ridges on the surface of the nonwoven fabric during manufacturing.
感熱収縮性繊維と非収縮性繊維とは高圧柱状流によって
相互に緊密に絡合せしめられている。高圧柱状流とは、
微細な直径のノズル孔を通して高圧で非圧縮性の流体を
噴出させて得られるものである。具体的には、ノズル孔
径０．００１〜０．１ｃｍ程度のノズルを用いて圧力５

である。このような高圧柱状流を繊維ウェブに作用させ
ると、構成繊維が運動し、隣接する他の構成繊維を相互
に緊密に絡合する。その結果、結合剤を付与しなくとも
強度の高い不織布を得ることができるのである。The heat-sensitive shrinkable fibers and non-shrinkable fibers are tightly entangled with each other by high-pressure columnar flow. What is high pressure columnar flow?
It is obtained by ejecting an incompressible fluid at high pressure through a nozzle hole with a fine diameter. Specifically, using a nozzle with a nozzle hole diameter of about 0.001 to 0.1 cm, a pressure of 5
It is obtained by jetting water at ~400 +r/cnl. When such a high-pressure columnar flow is applied to the fiber web, the constituent fibers move and the adjacent constituent fibers are tightly entangled with each other. As a result, a highly strong nonwoven fabric can be obtained without adding a binder.

収縮性繊維と絡合している非収縮性繊維の任意の二点間
の距離が、感熱収縮性繊維の収縮の発現により縮まるこ
とにより、非収縮性繊維の未絡合部が撓むのである。A large number of random ridges are formed on the surface of the grained pulley woven fabric according to the present invention. The ridges are formed as a result of bending of the non-shrinkable fibers. The bending of the non-shrinkable fibers is achieved by applying a high-pressure columnar flow to a fiber web consisting of heat-sensitive shrinkable fibers and non-shrinkable fibers to tightly entangle the side fibers, and then shrinking the heat-sensitive shrinkable fibers. arise. In other words, the distance between any two points of the non-shrinkable fibers entangled with the heat-sensitive shrinkable fibers is reduced due to the shrinkage of the heat-sensitive shrinkable fibers, and the unentangled portions of the non-shrinkable fibers are flexed. It is.

きる。The grained pulley woven fabric according to the present invention can be obtained by the following manufacturing method. First, a cotton mixture of latent heat-sensitive shrinkable fibers and non-shrinkable fibers is made using a card method or an air-lay method.
A fibrous web is created in the form of a sheet. Thereafter, a high-pressure columnar flow is applied to the entire fiber web to obtain a fiber fleece in which the constituent fibers are tightly entangled. By applying heat to the latent heat-sensitive shrinkable fibers in this fiber fleece to cause them to shrink, the grained pulley woven fabric according to the present invention can be obtained.
