立毛シート状物を提供するにある。In recent years, demands on the texture and feel of products have been increasing year by year, and there has been a strong demand for a napped sheet-like material which is flexible and has excellent elasticity and is excellent in shape stability. The fiber napped sheet obtained by nap-treating a sheet-like material obtained by impregnating and coagulating a polymer elastic body into a conventionally known polyester or polyamide ultrafine fiber nonwoven fabric has a large 20% modulus, and the vertical 20% modulus is 0.1 to 0.3. The modulus of 20% in the lateral direction was large when kg / mm 2, and the sensitivity when tailored to clothes was poor. In addition, a nonwoven fabric consisting of elastic fibers and non-elastic fibers is characterized by not being impregnated and solidified with a polymeric elastic material, but the overall 20% modulus is small, and the morphological stability during passing through the process and inferiority are poor. However, even when it was made into clothes, it was inferior in shape stability and sensitivity. The present inventors have found that the fiber napped sheet material has a 20% modulus of 0.1 to 0.3 kg / mm 2 in the vertical direction and 0.001 in the horizontal direction.
The present invention has been completed by discovering that the shape retention and sensitivity when tailored to clothes when it is about 0.03 kg / mm 2 are excellent. That is, the present invention has a 20% modulus in the vertical direction.
0.1 to 0.3 kg / mm 2 and horizontal direction 0.001 to 0.03 kg / mm 2
Another object of the present invention is to provide a fiber napped sheet-like material having a swelling feeling, a soft texture and an excellent touch feeling.

物、各種手袋などに好適である。The present invention relates to a sheet-like material comprising a polyamide ultrafine fiber and an elastic polymer, the 20% modulus of which is in the vertical direction.
It was between 0.1 and 0.3 kg / mm 2, a fiber napped sheet, characterized in that a transverse 0.001~0.03kg / mm 2, also 20% modulus of 0.1~1.0kg / mm 2 polyamide microfine A step of producing an entangled nonwoven fabric composed of polyamide ultrafine fiber-generating fibers that can be modified into fibers, a step of impregnating the entangled nonwoven fabric with an elastic polymer liquid and wet coagulating, and converting polyamide ultrafine fiber-forming fibers into polyamide ultrafine fibers 20% modulus of the resulting fiber napped sheet-like product in the vertical direction 0.1 to 0.3 kg
/ mm 2 , and the lateral direction is 0.001 to 0.03 kg / mm 2 . The polyamide ultrafine fibers constituting the fiber napped sheet-like product of the present invention are
The 20% modulus is in the range of 0.1 to 1.0 kg / mm 2 . 1.0kg /
If it is larger than mm 2 , 20% of the obtained fiber napped sheet material
Increased modulus, 20% modulus in vertical direction
20 modulus in the transverse direction is 0.03 when 0.1 to 0.3 kg / mm 2
Since it is larger than kg / mm 2, it lacks flexibility and is inferior in sensitivity when tailored and worn on clothes. On the contrary, 0.1k
If it is less than g / mm 2 , the 20% modulus of the fiber napped sheet-like product becomes too small and the process passability becomes poor, and the shape retention in the final product becomes poor. In the polyamide ultrafine fiber-generating fiber of the present invention, polyamide is, for example, 6-nylon, 66-nylon, 610-nylon, 11-nylon, 12-nylon, 26-nylon,
At least one polyamide selected from 210-nylon, 410-nylon, 76-nylon, and other spinnable polyamides having an aromatic ring.
If necessary, a monomer having a side chain may be copolymerized or a modifier may be added in order to reduce the concentration to the range of 0.1 to 1.0 kg / mm 2 . Further, in the case of 6-nylon or the like, a fiber having a desired modulus can be obtained by reducing the spinning draft at the time of melt spinning and crimping it as it is without stretching. On the other hand, is the other polymer that constitutes the ultrafine fiber-generating fiber a polymer that has a different solubility in polyamide and a solvent and has a low affinity, and that has a melt viscosity smaller than that of polyamide under spinning conditions? Or a polymer having a small surface tension, for example, polyethylene, polypropylene, ethylene propylene copolymer, ethylene octene copolymer, ethylene vinyl acetate copolymer, polystyrene, styrene acrylonitrile copolymer, styrene ethylene copolymer, polyester It is at least one kind of polymer selected from polymers such as. Then, fibers composed of polyamide and other polymer are mixed at a predetermined mixing ratio and dissolved in the same dissolution system to form a mixed system and spinning, a method in which they are dissolved in separate dissolution systems, and the spinning head is used. In the method of forming a mixed system by repeating joining-splitting a plurality of times and spinning, dissolving in separate dissolution systems and spinning by defining the fiber shape in the spinneret part, the polyamide component occupying in the fiber is 40%. ~ 80% by weight, and the polyamide ultrafine fiber component in the fiber is 5 or more,
Preferably, polyamide ultrafine fiber-forming fibers in the range of 50 to 800 are obtained. If necessary, the ultrafine fiber-generating fiber undergoes ordinary fiber treatment processes such as drawing and heat setting, and has a fineness of 2 to 15
Denier and polyamide The average fineness of the ultrafine fiber component (calculated value) is 0.2 denier or less, preferably 0.005 to 0.1 denier. The fibers are defibrated with a card, a random web or a cross-wrap web is formed through a web bar, and the obtained fiber web is laminated to have a desired weight and thickness. The fiber napped sheet-like material of the present invention having a small 20% modulus in the width direction as compared with the length direction has a higher degree of orientation in the length direction of the fiber than in the width direction, but the sheet is usually used in the manufacturing process. Since a random web does not require a special stretching step because it is stretched in the vertical direction to some extent, it is preferable that even a cross-lap web is stretched in the vertical direction in the manufacturing process and the degree of orientation in the vertical direction is high. Can be used for The weight of the fibrous web laminated with fibers is generally in the range of 100 to 2000 g / m 2 . Then
The fiber web is needle-punched by a conventionally known method to entangle the fibers to obtain a needle-punched nonwoven fabric. The number of punches is usually in the range of 200 to 2500 punches / cm 2 , and it is preferable that the fibers are sufficiently entangled in terms of stretchability and fullness. Next, the fiber-entangled nonwoven fabric is impregnated with and solidified with the elastic polymer liquid. The elastic polymer contained in the fiber entangled nonwoven fabric is, for example, polyester diol having an average molecular weight of 500 to 3000, polyether diol, polyester ether diol,
At least one kind of polymer diol selected from polylactone diol, polycarbonate diol, etc.,
Tolylene diisocyanate, xylylene diisocyanate, phenylene diisocyanate, 4,4'-diphenylmethane diisocyanate, 4,4'-dicyclohexylmethane diisocyanate, isophorone diisocyanate,
At least one organic diisocyanate selected from aromatic, alicyclic, and aliphatic organic diisocyanates such as hexamethylene diisocyanate, and at least an active hydrogen atom such as diol, diamine, hydroxyamine, hydrazine, and hydrazide. It is a polyurethane obtained by reacting at least one kind of chain extender selected from two low molecular weight compounds having a predetermined molar ratio. The stress at 100% elongation of the dry film is preferably 0.20 to 1.00 kg / mm
Use 2 polyurethane. If the stress at 100% elongation of the polyurethane is out of the above range, the elastic behavior becomes large or becomes hard, so that a product having a swelling and soft texture like natural leather cannot be obtained. Polyurethane is used as a polymer composition obtained by adding a polymer such as synthetic rubber, polyester elastomer or polyvinyl chloride, if necessary. Next, the production of the sheet-shaped substrate is carried out by dissolving a polymer mainly composed of an elastic polymer in a solvent or dispersing it in a dispersant, and further, a coloring agent, a coagulation regulator, a release agent for the polymer liquid. Agent, a plasticizer, a stabilizer, an antioxidant, a light-resistant stabilizer, etc. are added to the fiber-entangled nonwoven fabric as a polymer composition liquid obtained by blending the additives, and treated with a non-solvent for the polymer. The sheet-shaped substrate is solidified by a wet solidification method of solidifying, a dry solidification method of solidifying by removing a solvent or a dispersant by heating, or a combination thereof, washed if necessary, and dried. The amount of polyurethane or polyurethane composition in the sheet-shaped substrate is 10 to 10 by weight as solid content.
The content is 50% by weight, preferably 15-40% by weight. If the content of the polymer mainly composed of polyurethane in the sheet-shaped substrate is out of the above range, it becomes unfavorable because the stiffness is lost, the swelling feeling is not obtained, and the elastic behavior is increased. . The sheet-shaped substrate impregnated and coagulated with the polymer is a non-solvent for polyamide and the polymer, and is treated with a solvent or a decomposing agent for other components of the ultrafine fiber-generating fiber, so that the ultrafine fiber-generating fiber is made into a polyamide ultrafine fiber. A sheet-like base material which is modified into fibers and comprises an ultrafine fiber entangled nonwoven fabric and a polymer mainly composed of polyurethane. Next, the sheet-like base material composed of the ultrafine fiber entangled nonwoven fabric and the polymer mainly composed of polyurethane has a fiber nap surface mainly composed of ultrafine fibers on at least one surface. That is, after the thickness of the sheet-like base material is adjusted to a desired thickness or before the thickness adjustment, at least one surface of the sheet-like base material is raised by a raising machine, buffing treatment with sandpaper, etc. A napped surface mainly composed of is formed into a fiber napped sheet-like material. Then, in the case where the thickness of the sheet is not adjusted, the back surface is processed to a desired thickness to adjust the thickness. The product thickness of the fiber napped sheet material is preferably in the range of 0.25 to 2.0 mm, more preferably in the range of 0.30 to 1.5 mm. Then, the fiber napped sheet material is subjected to finishing treatment such as dyeing, kneading softening treatment, flame retarding treatment, water / oil repellency treatment and brushing as necessary. The fiber napped sheet-like product obtained in the present invention is a product having a swelling feeling, a soft texture, and a tactile sensation and excellent in shape retention when it is tailored into clothes. This fiber napped sheet-like product is suitable not only for clothing but also for clothing, interiors, shoes, bags, various gloves, and the like.
