上の問題が多かつた。 When fibers made of thermoplastic polymers are drawn and then heated to near their softening point, crimp is often observed in the fibers. This phenomenon is called the development of latent crimp due to heat treatment. Fibers with such properties are called fibers with latent crimp properties.
The crimp caused by the development of latent crimp is generally spiral-shaped and can impart strong elasticity to the fiber. Conventionally, a method has been known in which a web of fibers having latent crimp is heat-treated to produce a fiber structure such as a highly elastic nonwoven fabric whose form is stabilized by entanglement between fibers due to the development of latent crimp. ing. However, fibers with good latent crimp properties undergo large web shrinkage when crimp occurs, and this web shrinkage makes the width and thickness of the fiber structure uneven, causing density unevenness. Gender and homogeneity were difficult to coexist. Furthermore, the nonwoven fabric obtained in this way only maintains its shape through the intertwining of the fibers, so it has low strength and is prone to fluffing, resulting in many practical problems.

の問題が発生する。 Composite fibers (hereinafter sometimes referred to as thermoadhesive composite fibers) obtained by composite spinning two types of polymers with different melting points in a sheath-core type or parallel type are heat-treated at a temperature between the melting points of both components to create a low A method for producing a fiber molded article such as a nonwoven fabric is also known, in which bonding between fibers is developed by fusing melting point components. Even in this case, if the composite fiber has latent crimp properties, the web will shrink during heat treatment, resulting in large variations in quality of the resulting nonwoven fabric. When the above-mentioned composite fibers do not have latent crimpability, the structure of the fiber structure is stabilized and strong due to the fusion of the low melting point components of the composite fibers, and the shape change due to heat treatment is small and homogeneous. There are advantages. but,
Fiber structures made of fibers that do not have such latent crimp properties can be improved in bulk and elasticity by natural crimp of the fibers (crimps developed during fiber manufacturing processes such as spinning and drawing) or mechanically. Since it depends on the crimps imparted to the fabric, the crimping density is low and a soft texture or a texture rich in elasticity cannot be obtained. As a method of obtaining a soft and elastic fiber structure using heat-adhesive composite fibers that do not have latent crimp properties, it is also known to mix other fiber materials that do not deform by heat treatment for heat-adhesion. However, because the number of bonding points between heat-adhesive composite fibers is reduced and the adhesive strength between heat-adhesive composite fibers and other materials is insufficient, problems such as insufficient strength and shedding of fuzz occur here as well. .

When the composite form is a sheath-core type, it is easy to obtain fibers with low latent crimpability, but even in the case of a parallel type, latent crimpability can be eliminated by selecting the spinning and drawing conditions. ,Special Public Service 1977-
17807 is an example. The term "substantially free of latent crimp" refers to a parallel web having an area shrinkage rate of 5% or less when heat treated.

It also refers to a material that has latent crimpability such that the area shrinkage rate is 20% or more when the parallel web is heat-treated, and it may be either a composite fiber made of multiple components or a fiber with a uniform composition. In general, parallel composite fibers are latent crimpable, and even if they are fibers with a uniform composition, they can be rendered latent crimpable by selecting the raw material resin, spinning conditions, and drawing conditions.For example, by lowering the drawing temperature. It is generally effective to connect the

めである。 The heat-adhesive conjugate fiber (A) and the heat-adhesive fiber (B) can be mixed using a known device such as a spreader, a card, or a random webber. Heat-adhesive composite fiber
The reason why the amount of (A) is limited to 40 to 80% by weight is that if the amount of composite fiber (A) is less than 40% by weight, the shrinkage that occurs during heat treatment will be too large and the resulting fiber structure will be non-uniform. This is because if the content exceeds 80% by weight, the elasticity becomes poor, both of which are undesirable.

As a heat treatment method, any known heating means such as a heating furnace using hot air, superheated steam, infrared rays, or a heated roll can be appropriately selected and used. Through such heat treatment, the heat-adhesive fiber (B) develops latent crimpability and strengthens the entanglement with the surrounding fibers, and at the same time, the second component of the heat-adhesive composite fiber (A) and the heat-adhesive Both fibers (B) are fused at the point of contact between the fibers.

A fibrous structure characterized in that the form of (B) is stabilized by both adhesion between fibers due to the development of thermal adhesive properties.
