る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a single fiber in which a continuously spun filament made of a synthetic organic polymer material and crimped short fibers made of a synthetic organic polymer material are entangled, intertwined, and randomly mixed with each other. This invention relates to a nonwoven fabric for interlining made by joining webs made of bulky fiber layers.
従来不織布は通常の紡績繊維である繊維長が25

たものである。 Traditionally, non-woven fabrics have a fiber length of 25, which is normal spun fibers.
It is made into a nonwoven fabric by a dry manufacturing method using cut fibers of about 76 mm to 76 mm, or it is made of filament-like long fibers as seen in the spunbond method.

くる。 The former non-woven fabric is made from cut fibers of approximately 25 mm to 76 mm in size, which is processed by spinning and opening using a normal spinning machine, and then formed into a sheet using a known card or air flow type web forming machine. It is rolled out and a binder is applied to it to make a non-woven fabric. but,
The nonwoven fabric obtained by this dry process becomes a cloth-like material in which the fibers are evenly spread, but since the fibers are tightly bonded with a binder, it inevitably gives a paper-like feel rather than a woven fabric. , poor drapability,
Furthermore, in order to improve the strength of the nonwoven fabric, it is necessary to increase the amount of binder, and as a result, the above-mentioned drapability becomes worse and flexibility is lost.

ある。いずれも従来の不織布は芯地として種々の
問題点があつた。 The latter type of nonwoven fabric, so-called spunbond, is produced by spinning a polymer material, which is a fiber material, through a nozzle, collecting it and developing it into a sheet, and then bonding it with heat fusion or a binder, or using needles. It is formed by bonding fibers together by punching or the like, and the fibers themselves have almost no crimp, so the nonwoven fabric produced by this method is flat and more paper-like. All conventional nonwoven fabrics have had various problems as interlining materials.

揮させて芯地用として最適になしたものである。 In order to solve these conventional problems, the present invention combines short fibers with relatively large fiber diameters and sufficiently crimped fibers with continuously spun filaments with small fiber diameters. By doing so, it is an object of the present invention to provide a nonwoven fabric for interlining that is bulky, elastic, and has a soft texture. That is, the fiber diameter is 22μ
When forming a web by depositing continuously spun filaments made of the following synthetic polymer materials, a cut length of 51 with a crimp number of 10 opened threads/25.4 mm or more is obtained.
A group of relatively thick crimped short fibers made of a synthetic organic polymer material of less than mm in size is blown with an air stream from both sides of a group of continuous filaments that are spun simultaneously, so that the continuous filaments are entangled and each constituent fiber is mutually connected. Forms a layer of bulky fibers that are tangled and randomly intermingled. By doing this, the main constituent fibers of the nonwoven fabric are relatively thick short fibers with crimps, and these are joined by thin fibers of continuously spun filament, which eliminates the stiffness that had been a problem up until now. This solution solves the problem of poor drapability and imparts appropriate elasticity and strength to the nonwoven fabric, as well as exhibits flexibility and drapability, making it ideal for interlining.
以下本発明の一実施例を図面により説明する。 An embodiment of the present invention will be described below with reference to the drawings.

ント２を構成繊維のつなぎとしたものである。 As shown in FIGS. 1 and 2, the nonwoven fabric for interlining according to the present invention has a fiber diameter of 25μ or more and a cut length.
Short fiber length of 51mm or less and 10 crimp count/
Short fibers 1 of 25.4 mm or more and melt-spun drawn filaments 2 of extremely thin fiber diameter 22 μ or less are entangled, intertwined, and randomly mixed together to join each fiber cross contact point of a single bulky fiber layer. The short fiber 1 is the main constituent fiber, and the filament 2 is the link between the constituent fibers.

る。 In the above structure, if the short fibers used are less than 25μ, the bulkiness will be insufficient, and if the number of crimps is less than 10/25.4mm, the cushioning or spring properties of the fibers will be insufficient. , elasticity and flexibility become insufficient. Furthermore, since the filament fiber plays the role of connecting all the constituent fibers of the nonwoven fabric, which sequentially connects each of the relatively thick crimped short fibers, the filament fiber is sufficiently thinner than the short fiber and has a diameter of 22μ or less. This diameter is necessary for the short fibers to exhibit their spring properties.

いものである。 Regarding the fiber material made from the synthetic organic polymer compound constituting the interlining nonwoven fabric of the present invention, various materials such as polyester, nylon, acrylic, polyolefin, etc. are selected depending on the application, and among these, nylon, acetate, etc. As seen from the Young's modulus of the fibers, it is effective when producing a flexible interlining nonwoven fabric, and can be used for filament fibers, short fibers, etc. For example, nonwoven interlining fabrics that are generally made of polyester as the short fiber material and nylon as the filament material have excellent elasticity, bulk, and drapability, and have a good feel.

する方法を用いてもよい。 To bond the web consisting of a single layer of bulky fibers constructed in this manner, the fibers may be bonded together by dipping or spraying in a binder solution in the same manner as in normal nonwoven fabric manufacturing methods, or by spinning. Either a bulky molecular material with a melting point lower than that of short fibers is used for the filament fiber, or the spun filament itself is made into a side-by-side or core-sheath type composite spun fiber consisting of a low melting point component and a high melting point component, or a latent heat melting material is used. A method may also be used in which the fibers are mixed in advance and the mixture is thermally melted and bonded.
