“Prior art and problems” Conventionally, in order to obtain a pile knitted fabric having an animal hair-like appearance and texture, studies have been made on raw cotton or a finishing method used for the pile portion, but this is still the target. There are gaps between them, and the fact is that the gaps become even larger on an industrial scale. For example, as a typical example of raw cotton having animal hair-like texture, a pile knitting made of fibers to which an inorganic substance and a cellulose derivative are added, from the viewpoint of improving the fiber base material in JP-B-56-44163 and JP-B-56-44164. Textiles have been proposed.

However, the obtained pile knitted fabric is finished to a pile knitted fabric having gloss and color, especially softness, as compared with conventional fibers, but has a bulk, elasticity, napping property and coloring property which are lower than those of animal hair. And inferior. Also, JP-B-43-16896, JUN-48-158
16, Japanese Patent Publication No. 52-47053, etc. have tried to get closer to animal hair by providing a taper in the shape of single fiber from the viewpoint of improving the shape in the fiber axis direction, but the tip of the nap portion is Although the tactile sensation at that portion is improved due to the thinness, the lightness, bulkiness, elasticity, color development and the like of the entire pile portion are still insufficient. Further, pile knitted woven fabrics of flat cross-section fibers having improved fiber cross-sections are also available in the market, but their quality is very soft, and they are inferior in terms of bulkiness, elasticity and coloring. On the other hand, there are Japanese Patent Application Nos. 57-28373 and 59-60083 as examples in which the texture surface, especially the slimy feeling, is emphasized. Although the slimy feeling shows a considerable improvement, it is inferior to animal hair in terms of bulkiness, elasticity, softness, coloring and hair saliva.

"Means for solving the problems" In view of such circumstances, the present inventors have investigated the causes of these problems and examined the findings and characteristics of animal hair,
Focusing on the cross-sectional structure of the fiber, which is considered to be the biggest reason, it succeeded in solving the problem. In particular,
Animal hair-like texture and appearance by allowing a large number of pores to exist inside the fiber cross-section, that is, the lightweight feeling of the pile,
It has been found that characteristics such as bulkiness, softness, elasticity, coloring, and hair rubbing are excellently exhibited, and the above-mentioned problems can be solved. More specifically, the presence of a large number of pores in the fiber cross section increases the fiber cross-sectional area, so that the bulkiness is increased as compared to the same composition fiber having no pores, and the weight is the same. Even a pile knitted fabric in the basis weight gives a light weight feeling, and when the same bulk is used, the basis weight can be reduced. Further, in the color developing property, the transmitted light is scattered by the pores inside the fiber cross section to show an animal hair-like coloring effect.
Although the reason is unknown, the non-convergent property is further emphasized and becomes favorable, resulting in an animal hair-like finish.

The expanded fiber used in the present invention has an expansion ratio of 3%.
It is important that it is at least, and preferably at least 5%. The reason is that a pile knitted fabric comprising a fiber having an expansion ratio of less than 3% has no outstanding characteristics as compared with conventional fibers due to the insufficient foamability of the fiber. There is no significant difference in terms of texture, expressed in terms of bulkiness, softness, elasticity, and the like, and in terms of color development, hair sacking, expressed in terms of the non-converging properties of pile fibers.
The effect becomes remarkable as the expansion ratio of the fiber increases. The upper limit of the expansion ratio is not particularly limited as long as the physical properties of a single fiber, for example, the strength and elongation, the Young's modulus, etc., can withstand pile knitting and weaving, but it is more practical to suppress the expansion ratio to 100% or less. is there.

The expansion ratio referred to here is calculated by the following equation: Expansion ratio (%) = {[(B) / (S)]-1} × 100 (S): Specific gravity of expanded fiber (B): Expanded fiber Specific gravity of non-foamed fibers (blanks) prepared from the remaining composition except for the foaming agent only from the raw material composition of the present invention. The porous foamed fibers referred to in the present invention are fibers having a large number of pores inside the fiber cross section. However, porous fibers presumed to utilize the layer separation effect of a heterogeneous polymer mixture as shown in the representative examples of JP-B-58-18444 and JP-B-58-43483, and JP-A-52-103526. In the manufacturing process of the fiber seen in the representative example, a substance that can be extracted in advance is added to the inside of the fiber, and thereafter, the extracted porous fiber, and a hollow fiber having a continuous cavity in the center of the fiber are not included. A foamed fiber which has been made porous by gas during the fiber production process, Porous fiber or a hollow fiber producing method may be a foamed fiber obtained by combining more than one method or methods obtained by.

The fiber cross section of the foamed fiber used in the present invention is not particularly limited in view of the effect of the pile knitted fabric. In general, the cross-section of a foamed fiber becomes rounder when manufactured under the same spinning conditions as compared to a fiber cross-section of the same composition without a foaming agent. Here, when it is desired to further emphasize the animal hair-like pile knitted fabric, the effect becomes remarkable when a foamed fiber having a major axis / minor axis ratio of 2 or more is used. The upper limit of the aspect ratio is not particularly limited, but is preferably 15 or less when judged from the appearance and texture of the pile knitted fabric. By using foamed fibers with a flat fiber cross section, the fibers themselves look thicker, and the elasticity and softness that were not seen in conventional flat fibers without pores appear in pile knitted fabrics. Finished with animal hair. Further, the cross-section of the foamed fiber is a foamed fiber (hereinafter referred to as a double-walled fiber) comprising a core portion arranged in a sponge shape by a large number of holes and a wall partitioning the same, and a sheath having a structure distinguishable from the core portion. By using the structural foamed fiber) as the pile fiber, the color development of the pile knitted fabric is further improved.

In other words, the color developing property seen in animal hair, even with almost the same fineness, looks completely different in thickness and fiber surface gloss due to the difference between light and dark colors, and it differs from conventional synthetic fibers different. For example, a light color such as ivory, beige, or gray, which is thick and opaque appears to be emphasized, and as the color becomes darker, such as brown, black, etc., it becomes thin due to the addition of transparency and the gloss of the fiber surface. Regarding these phenomena, the animal hair was observed through an optical microscope and a scanning electron microscope, and as a result, it was concluded that the influence of the core existing in the animal hair fiber cross section was large. The reason is that the sheath part having a homogeneous structure and the porous core part having a sponge structure in the animal hair fiber cross section add complexity of animal hair coloring to the incident light that hits the animal hair and enters the naked eye. . That is, since the light color has a small coloring effect and the transparency of the fiber is high, the incident light passes through the sheath almost linearly and reaches the core. Here, it is almost irregularly reflected, and exhibits an opaque feeling as seen when an apparent inorganic substance or the like is added. Conversely, if the color is dark,
Since the coloring effect is large, most of the incident light is absorbed, the amount of irregular reflection at the core is reduced, and the opacity is visually reduced. For the above reasons, a pile knitted fabric having animal hair fiber cross-section-like structure, that is, a double structure foamed fiber as a pile composition becomes animal hair-like particularly in color development.

In the double-foamed fiber of the present invention referred to herein, a large number of pores and a core portion arranged in a sponge shape by a wall partitioning the pores are independent pores or pores communicating with each other. Or a large number of pores in which these are mixed are randomly dispersed in the polymer structure of the fiber composition or blocked by a film-like film, or a yeast-like structure of bread making, and furthermore, a sea island. Shape-like structure and the like.
Further, the sheath having a structure that can be distinguished from the core does not necessarily mean that the core does not include a hole. That is, a structure having such a denseness that it can be differentiated from the core portion is sufficient.

The addition amount of these blowing agents depends on the type of the blowing agent and the solubility of the total amount added to the acrylonitrile-based polymer solution, but is 3 to 100% by weight based on the weight.
Preferably it is 5 to 50% by weight. In setting the amount of addition, conditions other than the type of the foaming agent and the spinning dope state after mixing the foaming agent can be arbitrarily selected according to the fiber formation state and the fiber cross-sectional state after spinning. As a method for adding the foaming agent, a system in which the foaming agent alone or a mixed solution of the polymer with an organic solvent is directly mixed into the spinning dope tank, or mixed immediately before the spinning nozzle may be employed.

A nucleating agent may be added to the spinning dope as needed, depending on the foaming state of the foamed fiber and the production reason. The nucleating agent is an inorganic powder having an average particle diameter of 10 μm or less, preferably 5 μm or less, more preferably 2 μm or less. Examples of such a substance include non-metal oxides such as boron oxide and silicon oxide; Oxides, antimony oxides, zirconium oxides, titanium oxides, zinc oxides,
Metal oxides such as tin oxide; hardly water-soluble or insoluble metal hydroxides and metal salt compounds; and silicon compounds such as kaolin, talc, bentonite and the like, but are not limited thereto. Mixed use of more than one species is also possible. Further, a nucleating agent of an organic compound can be used, and examples thereof include cellulose esters such as cellulose acetate, cellulose propionate and cellulose butyrate, and they can be used in combination with inorganic particles.

The effect of these nucleating agents is to suppress local foaming during the formation of foamed fibers and to stabilize the manufacturing process, and particularly to reduce single yarn breakage due to local foaming after the drying process. In addition to the above effects, the cellulose ester also has an effect of improving the hair sag of fibers in the pile portion when foamed fibers are used for the pile knitted fabric.

Next, in the spinning method, the spinning stock solution adjusted as described above is discharged through a nozzle into an aqueous coagulation bath, and the slit shape of the nozzle is circular, rectangular, or any other irregular shape, and the one suitable for the purpose is used. be able to. As the coagulation bath conditions, it is preferable to use an aqueous solution of the polymer organic solvent for fiber formation, taking into consideration the coagulation for fiber formation, the solubility of the foaming agent used in the coagulation bath, and the shape of the fiber cross section. The temperature and concentration can be arbitrarily set within the range of the boiling point of the blowing agent or lower. Here, considering the solubility of the foaming agent in the coagulation bath means that the condition is such that the solubility of the foaming agent in the aqueous solution of the organic solvent is hardly soluble or insoluble. Specifically, the solubility of the foaming agent in the coagulation bath is 10% by weight or less, preferably 5% by weight or less. If the solubility of the foaming agent in the coagulation bath exceeds 10% by weight, the content of the foaming agent in the coagulated polymer yarn is drastically reduced, and an unsatisfactory foaming structure is not obtained in the subsequent foaming step, which is not preferable. When the temperature of the coagulation bath exceeds the boiling point of the foaming agent, the polymer yarn starts to foam, but the foamed fiber is crushed or fused in the subsequent fiber forming step, and it is difficult to obtain a satisfactory foamed fiber.

The coagulated polymer yarn can be drawn again in an aqueous solution of an organic solvent for the polymer or in the air, if necessary, and undergoes the next washing step. Here, the temperature of the water washing step can be arbitrarily set regardless of the boiling point of the foaming agent, but it is preferable to remove the solvent of the polymer from the fiber while leaving the foaming agent inside the fiber in view of forming the fiber, It is better to raise the washing temperature to promote the removal of the solvent. Moreover, you may extend | stretch in a washing process as needed. In this washing step, too rapid foaming has many problems in fiber formation. Therefore, it is better to set the washing temperature appropriately in consideration of the type of the foaming agent to be used and the solvent removal from the fibers.

The yarn thus obtained is dried by applying an oil agent thereto,
Further promotes fiber formation. At this time, if a certain amount of the solvent of the polymer is present in the water-washed yarn entering the drying step, fusion between the single fibers occurs and the fiber-opening property is reduced, and static electricity generated in the step is further reduced to reduce static electricity. It is better to attach an oil agent having an antistatic effect. In particular, when the added amount of the foaming agent is large, the content of the solvent in the washed yarn after spinning becomes high, and the fusion between the single fibers in the drying step increases. In order to solve this problem, it is preferable to use an oil agent having a large releasing effect in combination, and the effect of the silicone oil agent is particularly good. Examples of the silicone oil include dimethyl polysiloxane, modified polysiloxane such as epoxy group-containing polysiloxane and amino group-containing polysiloxane in addition to dimethyl polysiloxane and alkoxy polysiloxane, and the like.
Generally used after emulsification. Particularly, an epoxy group-modified or amino group-modified silicone oil agent is preferable from the viewpoint of improving the feeling of foamed fibers.

The drying step needs to be performed at a drying temperature of 100 ° C. or higher, which is higher than the boiling point of the foaming agent. If the drying temperature does not reach 100 ° C., the fibers will leave moisture inside, which will lower the physical properties of the fibers and hinder the subsequent fiber processing steps. If the temperature of the fibers does not reach the boiling point of the foaming agent or higher during the washing or drying step, the fibers are insufficiently foamed, which is not preferable. Next, if necessary, by performing drawing and heat treatment, a foamed fiber having excellent fiber properties can be obtained.
