Multiple electric flocking

Technical field

[0001] The present invention relates to a multiple electric flocking product in which a pile is flocked.

Background art

[0002] Conventionally, electric flocks have been used for various purposes such as chair upholstery, carpets, and vehicle interior materials. In many cases, nylon fiber or fiber fibers such as nylon are applied to a base fabric made of woven or knitted fabric, or a base material made of a resin sheet or a resin molded product, and then cut to a predetermined length. The pile layer is an electric flocking product having a single layer (hereinafter referred to as a single flocking product).

[0003] Further, as a special electric flocking product, a double flocking product is conventionally known. For example, Koko 43-24540 has a relatively long fiber length, and after planting a whole pile of two fiber length piles, the surface of the pile is further coated with an adhesive grease, and an extremely short fiber length. A backskin-like electric flocking product having a non-uniform uneven surface is described by flocking this pile.

[0004] On the other hand, recently, there has been a demand for an electric flocking product having a higher design and a high-class feeling. For example, by placing a pile of piles of the same fiber length on the pile surface that has been flocked on the entire surface, giving a high cushioning property that cannot be obtained with a single flocked product, and by flocking the outermost layer in a pattern There is a demand for a flocked product with a sense of quality and design.

[0005] However, double flocked products using nylon fibers, rayon, and other fibers that have been used for electric flocking in the past as well as the conventional force have a perpendicularity with the straightness of the flocked pile and the substrate. This is not sufficient, and there is a problem that the surface of the flocked surface is not smooth enough. Also, in the case of patterned flocking, the sharpness of the pattern formed by flocking (hereinafter referred to as flocked pattern) is inferior. So far, a product with an appearance quality that is satisfactory in terms of luxury has not been obtained.

[0006] Further, in pattern flocking, since external stress tends to concentrate on the pile at the end of the pattern, the pile collapses and the pattern becomes unclear in long-term use, so the durability of the pattern is poor. Is enough There was also a problem. In addition, the conventional double flocked product has a problem that when it is used for a chair upholstery etc. and the load is applied to the flocked surface for a long time, the needle sags more than the single flocked product and the cushioning property is immediately impaired. was there.

[0007] W099Z32695 discloses polytrimethylene terephthalate fiber used for electric flocking and a fabric using the same. However, since this fabric is only a single graft of polytrimethylene terephthalate fiber, the design and cushioning properties may be insufficient.

Therefore, there has been a demand for an electric flocking product having little pile sag, excellent cushioning properties, and having a soft hand.

Disclosure of the invention

Problems to be solved by the invention

[0008] The present invention has an object of providing a multiple electric flocking product in which piles are flocked, and has a good appearance quality, particularly in a patterned flocking product in which the outermost layer is flocked in a pattern. An object of the present invention is to provide a multiple electric flocking product that is excellent in sharpness, durability and cushioning properties and has a soft hand.

Means for solving the problem

[0009] As a result of intensive studies to solve the above problems, the present inventors have found that the object can be achieved by specifying the fiber material used for the pile portion of the multiple electric flocking product. The invention has been completed.

That is, the present invention is as follows.

[0010] 1. An electric flocking product in which a pile is flocked, wherein at least a part of the nozzle is made of polytrimethylene terephthalate fiber.

2. The multiple electric flocking product as described in 1 above, wherein the wool implanted in the lower layer excluding the outermost layer is made of polytrimethylene terephthalate fiber.

[0011] 3. The multiple electric flocking product as described in 1 above, wherein the wool implanted on the outermost layer also has a polytrimethylene terephthalate fiber strength.

4. The multiple electric flocking product according to the item 3, wherein the outermost flocking is planted in a pattern. 5. The multiple electric flocking product according to claim 3 or 4, wherein the outermost layer is sublimation transfer printed.

Hereinafter, the present invention will be described in detail.

The multiple electric flocking product of the present invention is an electric flocking product in which multiple piles are flocked. In the present invention, the term “multiple flocking” means that a single layer of a resin layer and a pile that is electrically flocked to one layer are stacked, and the layers are stacked in multiple layers. For example, a double flocked product is a product obtained by further applying a greaves layer to the surface of a pile that has been electroflocked to a greaves layer on a substrate, and then electric flocking the pile thereon. A triple flocked product is a product in which a grease layer and a pile are further stacked on the product.

[0013] The lowermost layer refers to a layer in contact with the substrate, and the outermost layer refers to a layer that is the surface of the multiple flocked product (the side opposite to the substrate).

Each pile layer that has been flocked in multiple layers may be flocked on the whole surface in which the pile is flocked substantially uniformly over the entire surface, or may be flocked in which the pile is flocked in a pattern. That is, all the pile layers of multiple flocking may be all-surface flocking, all-pattern flocking, or all pile flocking and pattern flocking may be mixed for each pile layer.

[0014] For example, it is possible to obtain a flocked product having both high cushioning properties and design properties by superimposing a patterned flock on a full flock. Moreover, it can also be set as the flocked product which has higher designability by further superimposing a pattern flocking on a pattern flocking. In the present invention, the pattern flocking refers to a state where the pile is not implanted on the entire surface and the flocked portion and the non-flocked portion are mixed.

[0015] In the multiple electric flocking product of the present invention, it is necessary that at least a part of the flocked pile forming the pile layer is a polytrimethylene terephthalate fiber. Ratio of put that polytrimethylene terephthalate fiber in the pile layer, the mass ^_0/0, preferably 30% or more, good Ri preferably 50% or more, more preferably 70% or more, most preferably 80% or more is there. When the ratio of the polytrimethylene terephthalate fiber is in the above range, the object of the present invention is sufficiently achieved.

[0016] The ratio of the polytrimethylene terephthalate fiber in the entire pile forming the flocked product is mass%, preferably 10% or more, more preferably 20% or more, and still more preferably. 30% or more, most preferably 40% or more.

[0017] The polytrimethylene terephthalate fiber may be used only for the lowermost pile layer, or may be used only for the uppermost layer, or may be used only for the outermost layer, or the lowermost layer and the intermediate layer, and the intermediate layer and the outermost layer. Used for. Most preferably, polytrimethylene terephthalate fibers are used in all layers of the pile.

In the present invention, examples of fibers other than polytrimethylene terephthalate fibers include, for example, polyethylene terephthalate fibers, cationic dye-dyed polyethylene terephthalate fibers, polybutylene terephthalate fibers, nylon 6 fibers, nylon 66 fibers, polyethylene fibers, and the like. Different fibers (bright, semidal, fuldal, etc.) of these fibers can be used for various desired fibers as long as they do not impair the purpose of the present invention, such as atypical cross-section fibers, original fibers, and pre-dyed fibers.

[0019] In the multiple flocking product, the flocking quality of the pile in the lowermost layer greatly affects the quality of the whole flocking product. When polytrimethylene terephthalate fibers are used for the lowermost pile of the multi-implanted product of the present invention, the straightness of the pile is highly perpendicular to the base material, so the surface of the lowermost flocked surface has very good smoothness. Have. As a result, the surface of the pile layer on which the hair is piled up on the surface is also improved in smoothness, and a very high quality multi-flocked product with excellent appearance quality can be obtained.

[0020] The reason why the use of polytrimethylene terephthalate fiber in the pile increases the pile linearity and the perpendicularity to the base fabric is estimated as follows.

[0021] In the multiple flocking product, an adhesive resin is applied to the surface of the lowermost pile layer, and the pile is electroplanted again on the resin layer. In general, water-based emulsion resin is used as the adhesive resin used for electric flocking. When fibers such as nylon fiber or rayon are used as the bottom layer pile, these fibers have high water absorption, so the moisture is absorbed in the adhesive resin applied to the surface of the fiber, and the nozzle swells and piles up. Deformation occurs. As a result, unevenness occurs in the adhesive resin layer itself, and the surface of the multiple flocked product is also inferior in smoothness.

[0022] In addition, the ability to remove excess pile that has not been adhered after flocking. In particular, after flocking the lowest layer pile, it is completely adhered to the resin layer, and the excess pile is removed. There is a need to. The removal method is generally a brushing or a stagnation like a liquid dyeing machine. Force to wash with water through highly effective machine At this time, the pile is deformed by external force, so the surface of the nozzle layer is less smooth.

[0023] Furthermore, when applying the adhesive resin to the lowermost pile surface, generally, the force using a method such as a doctor knife coater, roll coater, roll screen coater or the like is used. Since the layer is deformed by the force applied when applying the resin, the smoothness of the surface of the pile layer decreases.

[0024] Nylon fibers, rayon fibers, and polyethylene terephthalate fibers are inferior in instantaneous recovery against deformation. Therefore, when these fibers are used in the lowermost pile, the smoothness of the surface of the pile layer is reduced, and As a result, the surface of the multiple flocked product is inferior in smoothness.

[0025] On the other hand, when polytrimethylene terephthalate fiber is used for the lowermost pile, polytrimethylene terephthalate fiber absorbs moisture inside the adhesive resin and swells because the water absorption is very small. In addition, since the instantaneous recovery from deformation is excellent, it is possible to plant the upper layer with high pile linearity and perpendicularity to the base fabric. Becomes extremely smooth.

[0026] In addition, the multiple flocked product generally has a higher cushioning property than the single flocked product, but when used for a chair upholstery or the like, when a load is applied to the flocked surface for a long time, it is more than the single flocked product. There is a problem that sag of the pile occurs and the cushioning property is immediately lost. This sag is likely to occur especially in the lowermost pile, but if polytrimethylene terephthalate fiber is used in the lowermost pile, it is difficult to cause sag and the cushion durability is remarkably improved. .

[0027] Next, when polytrimethylene terephthalate fiber is used for the outermost layer pile, the tactile sensation is very soft, especially when planted in a pattern. It becomes a flocked product and can maintain its vividness for a long time.

[0028] In order for the flocked pattern to look clear, the uniformity of the pile length, the linearity of the pile, and the perpendicularity to the base fabric are greatly affected. Pattern flocking is a force obtained by electro-implanting a pile on the adhesive resin layer applied in a pattern. A pile planted at the end of the pattern is easily tilted or tilted by a slight external force! /, . [0029] When nylon fibers are used for pattern flocking, the pile absorbs the moisture inside the adhesive resin and swells, causing the pile to deform. In particular, the edge of the pattern is bent and tilted or tilted. Occurrence Then, the border between the patterned flocked portion and the non-flocked portion is blurred, and the flocked product is unclear.

[0030] In addition, when polyethylene terephthalate fiber is used for pattern flocking, there is almost no swelling of the pile due to moisture, and therefore, deformation, collapse, and inclination of the pile during flocking are unlikely to occur. However, the external force that acts on the pile when used for chair upholstery, etc. tends to concentrate on the pile planted at the end of the handle, so it deforms from the pile at the end of the handle for a long period of use. Slightly falls and begins to tilt. Since the polyethylene terephthalate fiber is inferior in recoverability to pile deformation, the sharpness of the pattern is gradually lost.

[0031] On the other hand, polytrimethylene terephthalate fiber has a very low water absorption, so that an extremely clear patterned flocked product that does not swell by absorbing moisture inside the adhesive resin can be obtained. . In addition, because it has excellent recovery from deformation, it is possible to maintain the sharpness of the pattern for a long period of time at which the deformation, tilting, and tilting of the pile are unlikely to occur.

[0032] In the present invention, the polytrimethylene terephthalate-based fiber is a polyester fiber mainly composed of trimethylene terephthalate units, and the trimethylene terephthalate units are preferably about 50 mol% or more, preferably Means 70 mol% or more, more preferably 80 mol% or more, and still more preferably 90 mol% or more. Therefore, the total amount of other acid components as the third component and Z or Daricol component is about 50 mol% or less, preferably 30 mol% or less, more preferably 20 mol% or less, and even more preferably 10 mol% or less. Includes included polytrimethylene terephthalate.

The intrinsic viscosity of polytrimethylene terephthalate is preferably 0.7 to 1.5 (dl / g), more preferably 0.8 to 1.3 (dlZg). The higher the intrinsic viscosity, the more excellent the recovery property against deformation.

[0033] As a preferable characteristic of the polytrimethylene terephthalate fiber, the strength is 2 to 5 cNZdtex, more preferably 2.5 to 4.5 cNZdtex, and further preferably 3 to 4.5 cNZdtex. The elongation is 30 to 60%, more preferably 35 to 55%, still more preferably 40 to 55%. The elastic modulus is 30 cNZdtex or less, more preferably 10 to 30 cNZdtex, still more preferably 12 to 28 cNZdtex, and particularly preferably 15 to 25 cNZdtex. The elastic recovery rate at 10% elongation is 70% or more, more preferably 80% or more, still more preferably 90% or more, and particularly preferably 95% or more.

[0034] Polytrimethylene terephthalate is synthesized by combining terephthalic acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under appropriate reaction conditions. In this synthesis process, one or two or more third components may be added to form a copolyester, or polyethylene terephthalate.

, Polyesters other than polytrimethylene terephthalate such as polybutylene terephthalate, nylon, and polytrimethylene terephthalate are blended (the content of polytrimethylene terephthalate during blending is preferably 50% or more by mass%. ), Or a latently crimped polyester fiber in which at least one component is composed of polytrimethylene terephthalate by composite spinning (eccentric sheath core type, side-by-side type, etc.).

[0035] Third components to be added include aliphatic dicarboxylic acids (such as oxalic acid and adipic acid), alicyclic dicarboxylic acids (such as cyclohexanedicarboxylic acid), and aromatic dicarboxylic acids (isophthalic acid, sodium sulfone). Isophthalic acid, etc.), aliphatic glycols (ethylene glycol, 1, 2-propylene glycol, 1, 4 butanediol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexane dimethanol, etc.), aliphatics including aromatics Glycols (1,4-bis (-hydroxyethoxy) benzene, etc.), polyether glycols (polyethylene glycol, polypropylene glycol, etc.), aliphatic oxycarboxylic acids (ω-oxycaproic acid, etc.), aromatic oxycarboxylic acids (キシ -oxybenzoic acid) Acid, etc.). In addition, a compound having one or three or more ester-forming functional groups (benzoic acid or the like or glycerin or the like) can be used as long as the polymer is substantially linear.

[0036] Further, a quenching agent such as titanium dioxide or the like, a stabilizer such as phosphoric acid, an ultraviolet absorber such as a hydroxybenzophenone derivative, a crystallization nucleating agent such as talc, a lubricant such as aerosil, a hinder Antioxidants such as dophenol derivatives, flame retardants, antistatic agents, pigments, fluorescent brighteners, infrared absorbers, antifoaming agents, etc. may be contained.

[0037] The polytrimethylene terephthalate fiber used in the present invention is, for example, as follows. Obtained by law.

[0038] A polytrimethylene terephthalate polymer having an intrinsic viscosity of 0.4 to 1.9, preferably 0.7 to 1.2 was melt-spun to obtain an undrawn yarn at a take-up speed of about 1500 mZ. After that, it can be extended by a method of stretching at a rate of about 2 to 3.5 times, a straight stretching method (spin draw method) in which a single spinning process is directly connected, a high speed spinning method (spin take-up method) with a take-up speed of 5000 mZ or more. Get fiber. Alternatively, a partially oriented undrawn yarn obtained by taking-up at a take-up speed of 2000 mZ or more, preferably 2500 to 4000 mZ can be used. In this case, the yarn is drawn and stretched at a ratio less than the natural draw ratio. Get fiber.

[0039] The obtained long fibers may be continuously bundled to form a tow, or the long fibers once wound in a package may be unwound again and bundled using a force lifter or the like. . Further, it may be drawn after forming a tow by bundling melt-drawn undrawn yarns.

[0040] The shape of the fiber may be round, triangular, L-shaped, T-shaped, Y-shaped, W-shaped, Yaba-shaped, flat, even in a cross section that may be uniform or thick in the length direction. (With flatness of about 1-3-4, W type, I type, boomerang type, wave type, skewer type, eyebrows type, rectangular parallelepiped type, etc.), polygonal type such as dogbone type, multileaf It may be a mold, a hollow mold, or an irregular shape.

[0041] The thickness of the single yarn of the polytrimethylene terephthalate fiber used for the needle may be appropriately set according to the use of the product and the pile layer of the multiple electric flocking product. For example, at the outermost layer of the product where the flocked surface directly touches human skin, such as chair upholstery, chair cover, car seat, etc., 0.2 dtex to 30 dtex, preferably 0.5 dtex to 20 dtex, more preferably ldtex to: LOdtex is there. Further, in the lowermost layer and intermediate layer of the multiple electric flocking product, or in the outermost layer such as carpet or bath mat, it is 0.5 to 100 dtex, preferably 5 to 80 dtex, more preferably 10 to 60 dtex, and most preferably 20 to 40 dtex. .

[0042] In order to obtain an electric flocking product, a pile obtained by cutting a bundle of hundreds of thousands to several million dtex of the above-mentioned tow or drawn yarn into an arbitrary length is used. The cutting machine for cutting may be any of a push cutting method (so-called guillotine cutter), a rotary blade method (rotary cutter), and the like. In addition, wet cutting that provides moisture when cutting may be employed.

[0043] The method for coloring the pile is not limited, but is not limited to raw material coloring, total dyeing, toe dyeing, For example, a method of dyeing before electrical flocking such as package dyeing, a post-dyeing after electric flocking, and a method of giving an arbitrary color or pattern by performing printing (including transfer printing), etc. are adopted. When coloring raw materials, it is possible to produce piles with good performance by selecting general pigments with high fastness. When dyeing yarn or pile, a disperse dye having high fastness is selected and used, and the dyeing temperature is preferably 90 to 135 ° C, more preferably 100 to 130 ° C.

[0044] Sublimation transfer printing may be applied as a method of coloring the pile. It is known that sublimation transfer printing can give a textile with a delicate design in a short time with dry heat. Electrical flocked fiber products using polyamide fibers and printed by sublimation transfer printing have a problem in that they cannot exhibit multicolor with a rich design because they are inferior in color depth and pattern clarity.

[0045] When sublimation transfer printing is performed on a fabric having polytrimethylene terephthalate-based fiber strength while being strong, a printed fabric having a clear pattern can be obtained. Furthermore, as in the present invention, the pile linearity and the perpendicularity to the base fabric are high, and for multiple electric flocking products, V, electric flocking fiber products with excellent sharpness and color depth. Is obtained.

As conditions for sublimation transfer printing, the same conditions as those for conventional sublimation transfer printing of polyethylene terephthalate fibers can be used. In order to achieve the object of the present invention, sublimation transfer printing is preferably performed under a reduced pressure atmosphere rather than under normal pressure.

[0047] Sublimation transfer printing may be continuous type or batch type. For example, as disperse dyes, azo, anthraquinone, nitrodiphenylamine and the like preferably have a pressure (vacuum degree) during dyeing of usually 266 to 4000 Pa, and a temperature of usually 150 to 220. C, preferably 150-200. C and time are usually 10 to 120 seconds, and may be appropriately selected according to fabric specifications such as fabric density. It is preferable to heat-set the multiple flocked product in advance so that thermal shrinkage occurs during sublimation transfer printing and printing does not shift. The heat setting conditions should be selected appropriately considering the sublimation transfer printing conditions (temperature and time).

[0048] In order to improve the design of the multiple flocked product, a color mix may be made by mixing piles dyed with different colors in any number and in any ratio. Alternatively, polyethylene terephthalate fibers can be dyed together with cationic dye-dyeable polyethylene terephthalate fibers and used for post-dyeing to make use of the difference in dyeability from polytrimethylene terephthalate fibers. A color effect can also be obtained. It is also possible to obtain a chambray-like design effect by changing the pile length.

[0049] Further, it is possible to obtain a multiple flocked product having antistatic properties by flocking using conductive fibers in combination.

[0050] In the present invention, it is preferable that the fiber used for the electric flocking is subjected to an electrodeposition treatment in order to improve the separation property and flying property of the pile. The chemicals used for electrodeposition are sodium chloride, potassium chloride, barium chloride, magnesium chloride, salt ammonium, sodium sulfate, magnesium sulfate, ammonium sulfate, sodium silicate. Inorganic salts such as potassium silicate, sodium carbonate and sodium sulfate, surfactants such as char-on activator, nor-on activator, amphoteric activator, and organic cages such as colloidal silica are appropriately blended. You can use it.

[0051] The adhesive resin for adhering the nozzle to the substrate can be appropriately selected depending on the use of the multiple flocking product. For example, polyvinyl acetate, synthetic rubber latex, natural rubber latex, acrylic ester emulsion, polyurethane resin , Polyester resin, salt vinyl, etc. Moreover, these rosins can also be blended and used. The amount of adhesive resin applied is within a range that satisfies the performance required for multiple flocking products, depending on the concentration and viscosity of the adhesive resin. For example, the coating amount can be arbitrarily selected in the range of 150 to 500 gZm ² , and preferably 200 to 400 gZm ² .

[0052] The method for applying the adhesive resin to the substrate may be a doctor knife coater, roll coater, roll screen coater, or the like, which is not particularly limited. When performing pattern flocking, it is only necessary to apply adhesive flocking to a desired pattern shape using a roll 'screen' coater and perform electric flocking.

[0053] As a base material for flocking, there can be used a nonwoven fabric, a woven fabric, a knitted fabric and the like, a resin film, a resin molded product, a metal, and the like, which are not particularly limited. As a fabric that is not particularly limited in material, fabrics such as polyester fiber, polyamide fiber, polypropylene fiber, cellulose fiber, and acrylic fiber can be used. When used for carpets and other rugs, a glass fiber scrim may be attached to stabilize the dimensions of the base fabric. Furthermore, it may be coated or laminated with a sardine or foam material (such as vinyl chloride). Also, the carpet construction is convenient Or as a tile carpet cut to a certain size.

[0054] The length of the pile can be selected according to the product application and the thickness of the pile to be used, and is preferably 0.2 to 20 mm, more preferably 1 to 15 mm, and still more preferably. 1-10 mm, most preferably 1-5 mm.

[0055] Density of planting is pile layer one layer per preferably 50~: L000gZm ^2, more preferably 6 0~600gZm ^2, more preferably from 80~300gZm ^2. When the density of the bristles is less than 50gZm ^2, there is a case where aesthetics and cushioning required as a multiple electrical flocking products is insufficient. On the other hand, if the density exceeds lOOOgZm ² , there may be a hard texture, or the piles may be connected at the time of flocking to contact the electrode plate, generating a so-called spark and making electric flocking difficult.

[0056] In electroflocking, a high-voltage electrostatic field is generated between opposing electrodes, a base material coated with an adhesive resin is placed on one electrode side, and a charge is applied to the electrodeposited pile. Then, pile the hair by flying the pile toward the substrate from the electrode electrode on the opposite side.

[0057] As a method of flying the pile, there are (i) a down method (a method of flocking the pile by flying from above), (mouth) an up method (a method of flocking the pile by flying from below) There are many down methods, but it is not limited to these.

[0058] The electrode interval is changed according to the pile length. When the pile length is short, the electrode spacing is reduced. When the pile length is long, the electrode spacing is increased. For example, when the pile length is 0.5 mm, the electrode interval is preferably 50 mm or more. When the pile length is 3 mm, the electrode interval is preferably 200 mm or more. If the distance between the electrodes is sufficiently large with respect to the pile length, the distance that the piles fly will be increased, and it will be possible to cast deeper into the adhesive resin layer, thus improving the adhesive strength of the nozzle. The voltage applied to the electrodes is arbitrarily set within the range of 10 to: LOOKV depending on the electrode spacing, pile length, flocking density, electrodeposition treatment conditions, etc. Also, move the base material up and down during flocking so that the nozzle is thrown more strongly into the adhesive resin layer.

[0059] After flocking, in order to completely bond the pile, the adhesive resin is subjected to heat treatment for drying and crosslinking reaction. The heat treatment temperature is a temperature suitable for the type of adhesive resin and the type of crosslinking agent. It can be done in degrees or time. After the heat treatment, it is preferable to carry out a water washing treatment using a hair brush or a dyeing machine in order to remove the excess pile that is not adhered.

[0060] The multiple electric flocking product of the present invention can be manufactured by repeating the electric flocking process a predetermined number of times. In particular, in the flocking of the lowermost layer and the intermediate layer, it is preferable to reliably remove the excess pile in order not to decrease the adhesive strength when adhering to the uppermost layer and the intermediate layer. The invention's effect

[0061] The multiple electric flocking product of the present invention has good appearance quality, and is particularly excellent in the sharpness and durability of the flocking pattern in a flocking product in which the outermost layer is flocked in a pattern.

Polytrimethylene terephthalate having an intrinsic viscosity [V] of 0.92 was spun at a spinning temperature of 265 ° C. and a spinning speed of 1200 mZ to obtain an undrawn yarn. Next, hot roll temperature 60 ° C, hot Drawing was performed at a plate temperature of 140 ° C., a draw ratio of 3 times, and a drawing speed of 800 mZ to obtain a drawn yarn of 88 dtex Z72 f (single yarn fineness of 1.2 dtex).

The strength, elongation, elastic modulus, and elastic recovery at 10% elongation of the drawn yarn were 3.3 cN / dtex, 46%, 20 cNZdtex, and 98%, respectively.

Here, the elastic recovery rate at 10% elongation was determined by the following method.

The fiber was attached to a tensile tester with a distance between chucks of 10 cm, stretched to a stretch rate of 10% at a pulling speed of 20 cmZ, and left for 1 minute. Then, contract again at the same speed and draw a stress-strain curve. The elongation at the time when the stress became zero during shrinkage was defined as the residual elongation (E), and the elastic recovery rate was determined according to the following formula.

Elastic recovery at 10% elongation (%) = [(10-E) / 10] X 100

[0072] The intrinsic viscosity [η] (dl / g) is a value determined based on the definition of the following equation.

[Number 1]

[η] = I i m (TJ r-1) / C

c → o

[0073] In the formula, r? R is obtained by dividing the viscosity at 35 ° C of a diluted polymer solution dissolved in an o-chlorophenol solvent having a purity of 98% or more by the viscosity of the solvent measured at the same temperature. Value, defined as relative viscosity. C is the polymer concentration expressed in gZlOOml.
