Description

200402488 (2) Description of the invention: [Technical collar of the invention 3] Field of the invention The present invention relates to a flat multi-filament woven fabric. More specifically, the present invention relates to a woven fabric comprising a multi-filament yarn composed of a multitude of man-made yarns, and the delta hai yarn has a flat cut profile and is on each side. The cross section contains two or more neckings; the woven fabric has a soft hand, practically high water absorption, abrasion resistance, and perspective resistance [prior art] φ! 〇 BACKGROUND OF THE INVENTION Nowadays, many have poor air permeability Types of shuttle fabrics have been provided for sportswear and uniforms. As for the low-permeability rear fabric, a high-density shuttle fabric made of synthetic fibers (such as' polyacetate or polyurethane fiber) & a coated shuttle fabric (which is formed on a shuttle fabric-resin and Coating) and 15 calendered woven fabrics. ^ However, the high-density woven fabrics, coated and light-woven woven fabrics generally have low softness (hard feel), and the surface of these fabrics has 1 · abrasion resistance (abrasion resistance), so it is necessary Improve these types of woven fabrics. Synthetic fibers (e.g., poly and polyamide fibers) have excellent physical and chemical properties, so they can actually be used in different applications, such as fabrics and industrial applications. In particular, these polysilicon fabrics have excellent mechanical strength, dimensional stability, and easy maintenance properties. Therefore, different types of woven fabrics formed from synthetic fibers (e.g., polyester fibers) have been widely used. However, in addition to the excellent properties mentioned above, the woven fabrics of Wei Wei (such as Juzizhi) have high transparency. Therefore, when the high-transparency synthetic fibers are formed into a fabric and the fabric is used as a top ', a problem occurs in that clothing (in other words, underwear) worn in the top can be seen. 5 As a method for solving the above-mentioned problems, it is known to distribute inorganic fine particles (for example, titanium dioxide particles) into these synthetic fibers. This method results in synthetic fibers having an increased opacity ' and thus can improve anti-see-through properties. However, the woven fabric formed from the opaque synthetic fibers must still have an increased weave density to prevent light from penetrating the gap formed between the 10 yarns that form the woven fabric. This increase in weave density causes a problem that the resulting woven fabric has reduced softness. In the example of a woven fabric used for interior decoration materials (for example, curtains), both the anti-perspective property (in other words, the prevention of see-through objects and moving people = shells) and the penetration of light must be high. However, those properties are often different from each other 'and are therefore extremely difficult to achieve together. 20

For this reason, the factory usually arranges-thin lace money on the windows ϋ 2 trough 襕 curtains arranged indoors; closing the mess at night and closing the lace curtains during the day are called anti-perspective and lighting = require . However, in general, the 'thick _ curtain' has excellent visibility and poor light transmission f, and the -qi edge window blouse is only anti-perspective f at night and foot, and also during the day. Therefore, it is necessary to solve this P = to solve the problem, for example, a yarn containing ⑼ fiber yarn (its order =, such as titanium dioxide) and a black colored poly ray yarn 、,,,, and can reflect and absorb light Of pigments)

6 200402488 Curtains are disclosed in, for example, Japanese Patent No. 3167586; the reflection of Wei from a fabric or 'Λ object (which is a fabric of Anzai lustrous glossy yarn on the surface of n _ edge), which has a high degree of protection from Outdoors can be seen through curtains to the nature (this is due to the scattered light when the light returns to the brilliance of the fabric 5 surface), and satisfactory light transmission properties and air permeability, /, such as unexamined in Japan Patent Publication No. 2000_237,036, and a light-blocking fabric with a black light-shielding layer formed on the surface of the fabric are disclosed in, for example, Japanese Unexamined Patent Publication No. 62_133,787. 10 The above mentioned problem of forming a light-blocking fabric and a light-blocking curtain with a black light-blocking layer on the surface of the fabric is that when the light transmission property is poor, the room where the curtain is installed will be dark and the room where the curtain is installed. Create a heavy atmosphere. Similarly, the reflective curtain has high light transmission properties. However, the problem of the reflective curtain is that the anti-perspective property of the reflective curtain (especially within 15 minutes) is insufficient, and the wide plain cloth gloss yarn can cause a dazzling gloss on the reflective curtain. . As mentioned above, a woven fabric having both sufficient light transmission properties and excellent anti-see-through properties has not been provided and can be practically used. Furthermore, the disadvantage of woven fabrics made from synthetic fibers is that they are less absorbent, and in particular, the wicking properties of synthetic woven fabrics are worse than those made from natural fibers (e.g., cotton fibers). As a method for improving the water-absorbing property and sweat-absorbing property of a synthetic fiber woven fabric, a method of applying a hydrophilic agent to the woven fabric to increase the water absorption is known. Similarly, in applications such as shirts, sportswear, and uniforms, 200402488 needs to further improve water absorption and sweat absorption properties. Under the above-mentioned circumstances, there has been a strong demand for rayon woven fabrics (especially synthetic woven woven fabrics) with soft feel, high transparency, and excellent water and sweat absorption properties. 5 [Akichi] Summary of the invention The object of the present invention is to provide a flat multi-filament yarn shuttle with a high soft feel, high water and sweat absorption properties, abrasion resistance, appropriate air permeability, light transmission and high quality.

The anti-see-through textile material of the present invention includes a flat multi-filament woven fabric of a specific embodiment (3) of the present invention. The diagram is briefly explained. The first picture is applicable to the present invention. 15 Flat multi-filament yarn woven fabric of the invention is an illustrative example diagram of a cross-sectional profile of a flat multi-filament yarn; FIG. 2 is another flat multi-straight that can be used in the flat multi-filament yarn woven fabric of the present invention. An explanatory example diagram of a cross-sectional profile of a silk; and FIG. 3 is an explanatory example diagram of a cross-sectional profile of another flat multiple-filament that can be used for the flat multi-filament yarn shuttle fabric of the present invention. ] BEST PRACTICE MODE OF THE INVENTION The inventor of the present invention has discovered that in a woven fabric comprising multiple straight yarns as warp and / or weft yarns, each silk yarn contains a plurality of individual yarns, and each yarn Contains a man-made fiber to form a polymeric material and has A flat cross-section 11 200402488 surface profile; in the example, the cross-sectional profile of each individual yarn, on the flat profile, has a number on each side section relative to the longitudinal centerline of the flat profile 3 or more (preferably 4 or more, still more preferably * to ㊈ projections protruding outward from the longitudinal centerline of the flat profile; and on the 5 flat profile, in relation to There are a number of 2 or more (preferably 3 or more, still more preferably 3 to 5) on each side section of the longitudinal centerline of the flat outline; the necks formed between the protrusions; The protrusions and necking are formed approximately symmetrically with respect to the longitudinal centerline of the flat wheel, respectively; and the riding degree of the respective 10 15 20 κ domain surface contour can be determined by the maximum length of the flat contour in the longitudinal direction and The ratio (B / C1) of the maximum width (C1) in the direction intersecting at right angles to the longitudinal direction indicates that the ratio of the flat contour is controlled in the range of: to ^; ⑴ in the woven fabric produced In flat multi-filament yarns, the flat individual yarns are in contact with each other flatly at their flat ends, and At the crossing portion of the L weft of the woven fabric, the flat yarns of these dense rhymes are easily slipped and spread due to the pressing pressure of the warp and weft yarns crossing each other, so as to form a wide and dense cross in the woven fabric. In this case, the gap between the individual flat yarns becomes smaller; and ⑺ there are many protrusions and numerous _ at the flat clearance where the respective flat yarns are in close contact with each other, so the thick seam, ,, and friction * It becomes low, so the flat, straight, and rhombic materials produced by the material have a softness (elasticity) and low air permeability. For eight congeners, the inventors of the present invention have found that most of the feet formed around the flat yarns of each reel will knock on the reeds. Therefore, the shuttle fabric of the present invention has excellent water-absorbing and sweat-absorbing properties.

12 200402488 Furthermore, 'the inventors of the present invention have discovered that the majority of protrusions and necking around the respective flat yarns will cause the friction of the property around the respective flat yarns'. Therefore, the shuttle produced by the present invention The fabric has excellent abrasion resistance. Still, the inventors of the present invention have found that in the woven fabric 5 of the present invention, most of the protrusions and necking formed around the respective flat yarns As a result, around the roughened surface, it can reflect the light transmitted through the surface by irregular reflection and light reflection, so it can reduce the perspective of the woven fabric and prevent the object from being seen through the woven fabric, but The amount of light transmitted through the woven fabric (the amount of light irradiated through the woven fabric) is not significantly reduced. 1〇 # The 'inventor of the present invention has found that the 4 of the present invention can be appropriately controlled by appropriately establishing the cover factor of the flat multi-filament yarn shuttle fabric in the range of _ to 3500' The air-permeable, water-absorbent and sweat-absorbent properties, abrasion resistance, and anti-see-through properties of the shuttle fabric of flat multi-filament yarns can provide different types of textile materials with the properties mentioned above. 15 Shumingwei—Based on the results of completed studies mentioned above. The shuttle fabric of the present invention is a flat multi-filament yarn comprising a plurality of multi-filament yarns as warp and / or weft yarns, each silk yarn comprises a plurality of individual man-made yarns, and the yarns comprise fiber-made man-made polymers ( The main component) has a flat cross-section rim. 20 In the above-mentioned flat multi-filament yarn woven fabric (for example, refer to the section on the two sides of the wheel temple 13 200402488 2 = inspection center line), there are formed on the wheel-edge section respectively. 4 5 protrusions ^ 3 protrusions protruding outward from the longitudinal centerline (5 in FIG. 1 (in the first picture!)) And Λ two or more protrusions are formed between the protrusions The multiple neckings 4 are approximately ^ 3 auxiliary), the protrusions necking 2 relative to the longitudinal centerline 2 snoring β Ran. In the cross-sectional profile of Figure 1, the cross-sectional profile is flat :: the maximum length in the direction of the longitudinal center line ⑻ the maximum width in the direction perpendicular to the wheel direction (C㈣ 丰 (B / C1) table No, it ranges from 2 to 6.

In the cross-sectional profile of each individual flat yarn, 3 or more protrusions and 2 or more neckings are formed in one side section of the flat wheel 10 temple, and are approximately symmetrical to the above-mentioned lifting. And on one side section (relative to the longitudinal centerline of the flat wheel corridor), open on the opposite side section of the flat wheel temple into 3 or more shape-symmetrical protrusions and 2 or more Necked.

In the cross-sectional profile 15 of the respective flat yarns of the many straight yarns mentioned above, the number of protrusions on each side of the flat flat profile is 3 or more, preferably 4 or more , Still better. Likewise, the number of neckings on each side of the flat corridor is 2 or more, preferably 3 or more, and still more preferably 3 to 5. Similarly, the flat cross-sectional profile is 2 to 6, preferably 3 to 50. If the number of protrusions is 2 or less and the number of necking is 1 or less, The surrounding has an increased friction resistance, so in the warp and weft intersecting portions of the woven fabric (in which the warp and weft yarns exert a pressing pressure on each other), the sliding application of the respective yarns becomes Insufficient 'breathability of the woven fabric will become difficult to control, and the abrasion resistance of the woven fabric produced will be insufficient; the decrease in the number of necking will cause insufficient water absorption and sweat absorption properties of the woven fabric; And the light scattering effect around the individual filaments is insufficient, so the woven fabric produced will have unsatisfactory anti-see-through properties. 5 In the woven fabric of flat multi-filament yarns of the present invention, the flatness (B / C1) of the cross-section of each of the flat multi-filament yarns is 2 to 6, preferably 3 to 5. If the cross-section is flatness less than 2, the bending resistance (stiffness) of the respective yarns is too high, and the resulting woven fabric will have insufficient softness, so that a target woven fabric with a soft feel cannot be obtained. 10 Similarly, when the flatness of the cross-section is less than 2, the slips of the respective yarns in the multi-filament yarns of the warp yarn 'weft intersecting portion' of the woven fabric are spread (because of the (Compression pressure) will become insufficient, the gap between the warp and weft cannot be sufficiently small, and the size of the gap between the yarns cannot be sufficiently small, so the permeability of the woven fabric becomes difficult to control to the desired 15 degree. Similarly, it is difficult to produce each yarn having a flatness in cross section (B / C1) of more than 6. In the cross section of the flat yarns that can be used for the flat multi-filament yarns of the shuttle fabric of the present invention, the maximum width (C is in a direction perpendicular to the longitudinal centerline of the flat raceway 20) The preferred range of the ratio of the smallest width torso (ci / c2) is from L05 to 4.00, and more preferably from U0 to 2.50. As mentioned above, the ratio (C1 / C2) is-one kind of yarn per individual flat yarn Parameters related to the necking depth. If the ratio (C1 / C2) is less than ⑽ (in other words, the necking depth is too small), the surrounding surface of the resulting flat yarn will have too high financial friction 15 200402488 The rubbing property, the resulting woven fabric will have too high breathability and insufficient abrasion resistance, anti-perspective properties, and water and sweat absorption properties. Similarly, if the ratio (c 1 / C2) is greater than 4.0 (each flat) The necking depth of the yarn is too large), the necking effect will be saturated, and the disadvantages of the woven fabric are that the yarn formation process is unstable, and the resulting yarns will crack along the necking. And the uniformity in the cross-sectional profile of the respective yarns will decrease. In each of the figures 2 and 3, the display A specific embodiment of another cross-sectional profile of the respective flat yarns that can be used for the flat multi-filament yarn shuttle fabric of the present invention. 10 The cross-section of the straight yarn 1 shown in FIG. 2 has similarities to those of FIG. Profile, which has some protrusions and necking formed in the two-side section of the longitudinal centerline 2, except that the profile of the protrusion in Fig. 2 is an elliptical arc (which extends along the major axis of the ellipse) Therefore, the elliptic arc form is more gentle than the circular solitary protrusion in the first figure, so the necking depth in the second figure is smaller than that in the second figure. 15 The cross-section wheel of the straight wire 1 shown in the third figure Some protrusions and neckings are formed on the two side sections of the longitudinal centerline of the flat wheel, and the number of each side section of the flat contour is 4 and 3. In the third figure, The protrusion 3 a is smaller in visibility and southness than the other three protrusions 3, so the depth of the necking 4 formed in the two sides of the protrusion 3 a (in other words, from the protrusion 20 The top of 3a to the bottom of necking 4a) is smaller than that of other necking 4. As mentioned above, the cloth surface of the flat multi-filament shuttle fabric Cover factor ranges from 800 to 3500, which can establish appropriate properties and performance according to the needs of the woven fabric. The cover factor (CF) of the woven fabric can be defined by the following equation. 16 200402488 CF = (DWp / l. L ) 1 / 2xNWp + (DWf / l. 1) 1 / 2xMWf In the above-mentioned equations, DWp represents the total thickness of the warp yarn (fentex); MWp represents the weave density of the warp yarn (yarn / 2.54 cm); 5 DWf represents the total thickness of the weft yarn (fentex), and MWp represents the weave density of the weft yarn (yarn / 2.54 cm). In the flat multi-filament yarn shuttle fabric of the present invention, if the surface of the fabric is covered The coefficient (CF) is less than 800, and the gap between the warp and weft is large. It is difficult to control the air permeability of the woven fabric to a desired value, and it is also difficult to produce a woven fabric with a high degree of anti-perspective properties desired. . Similarly, if the cloth cover factor (CF) is greater than 3500, the resulting woven fabric will have sufficient softness and unsatisfactory light transmission (lighting properties). 15 20 Can be used to form a flat j-filament yarn shuttle fabric that can be used to test multiple straight lines. The ribbon is made of synthetic polymers, which can be selected from fibrous synthetic polymers, for example, nails. ^ 酉, polyamines, polyvinylidene chloride, and propylene resins; fiber-forming polymers, such as cellulose acetates and recycled polymers (such as

There is no limitation on the total thickness of the multi-filament yarns and the thicknesses of the respective flat yarns that can be used in the shuttle fabric of the present invention, as long as the target 10 shuttle fabric of the present invention can be obtained. In general, the total thickness of the yarn is preferably 30 to 170 cents taxi (more preferably 50 to 100 cents taxi), and the thickness of each yarn is preferably 0.5 to 5 cents taxi (more (1 to 4 cents taxi). Similarly, the number of twists of the flat multi-filament yarn used in the flat multi-filament yarn woven fabric of the present invention is not limited as long as the object 15 woven fabric of the present invention can be obtained. In other words, an appropriate twist number can be established depending on the purpose of the target woven fabric and the desired properties. Generally speaking, the twist number is preferably 0 to 250,000 revolutions / meter, more preferably 0 to 600 revolutions / meter. The multi-filament yarn that can be used in the shuttle fabric of the present invention can be deformed using the false twist square 20 method, the TASLAN method, or the air-jet texturing method (for example, air-jet interlacing method), as long as it can be obtained The target woven fabric of the present invention. In the woven fabric of the present invention, the warp and / or weft yarns constituting the woven fabric must be composed of the multiple straight yarns, which, as mentioned above, include a plurality of individual yarns having a flat cross-sectional profile. In other words, 'the flat multi-filament yarns can be used as one of the warp and wefts, or as any of the warp and wefts, and the dagger type of the warp and weft can be different from reading the flat multi-filament yarns. Yarn composition. ^ Different yarns may be selected from monofilament yarns, multi-filament yarns and staple fibers. ^ Some different yarns can have specific properties, such as antistatic properties, brilliance, stalks, brothers. Similarly, in the warp and / or weft yarns usable in the shuttle fabric of the present invention, a small amount of yarns or fibers different from the respective flat yarns and the flat multi-filament yarns can be used together. Use as long as the target woven fabric of the present invention can be obtained. ^ In the flat multi-filament yarn shuttle fabric of the present invention, the content of the flat multi-filament yarn is preferably 10 to 100% by mass, more preferably 20 to 100% by mass, and still more preferably 4G to The loo mass% is based on the total mass of the woven fabric. The flat multi-filament yarn for the shuttle fabric of the present invention can be manufactured by using a nozzle for a flat yarn. For example, a nozzle yarn having a spinning hole having a cross-sectional profile as shown in FIG. 2_e can be provided. This is shown on page 5 of Japanese Unexamined Patent Publication No. 56.107, 〇44. The flat multi-filament yarn woven fabric of the present invention can be manufactured using a conventional knitting procedure, wherein the flat multi-filament yarn manufactured as mentioned above can be used as a warp and / or weft, and the conventional dyeing can be utilized. And modification procedures to stain and modify. In the case where the flat multi-filament yarns are flat polyester multi-filament yarns, the produced woven fabric can be subjected to a mass-reduction treatment by alkali. Similarly, in the modification procedure, the woven fabric may be subjected to a water absorption enhancement treatment (by coating or impregnating a water absorbing agent, for example, an anionic hydrophilic polymer compound), or a water repellent treatment (by coating 200402488, m). Water-repellent agents, such as water-resistant fluorine compounds), UV-blocking treatment (by coating a dispersion of ultra-fine metal oxide particles), antistatic treatment, deodorant coating treatment, mothproof agent coating treatment, and One or more processes of the light storage agent coating process. In a specific embodiment of the flat multi-filament yarn shuttle fabric of the present invention, the thickness of the warp and weft yarns and the weave density of the warp and weft yarns are controlled to a certain degree, so that the cloth surface coverage factor of the woven fabric is generated. The range of (CF) is 1500 to 3500. In a specific embodiment (1) of the present invention, the woven fabric covering number 10 is preferably 1500 to 3000 and more preferably 1500 to 2500. Similarly, in the specific embodiment (1) of the present invention, the twist number of the flat multi-filament yarn is preferably 0 to 2500 revolutions / meter, and more preferably 0 to 600 revolutions / meter. More preferably, it is 0 revolutions / meter (in other words, no twist). In a specific embodiment (1) of the present invention, the woven 15 fabric of flat multi-filament yarns preferably has a permeability of 5 ml / cm 2 or less, more preferably 4 ml / cm 2 • Seconds or less, still more preferably 0, 丨 to) ml / cm² • s. The air permeability can be measured in accordance with JIS L 1096η " 8, 6.27.1, Method A (using a Fraser type tester). In a specific embodiment (1) of the present invention, the woven 20 fabric of flat multi-filament yarns preferably has a water absorption speed of 40 mm or more, more preferably 50 to 70 mm, which may be in accordance with JIS L 1096-1998, 6.26.1 (2) method (B) (Berrick method) to measure; and abrasion resistance of 50 abrasion or more, more preferably 80 abrasion or more, still more preferably 100 abrasion or more. In a specific embodiment (1) of the present invention, if the surface of the woven fabric covers 20 200402488 and the coefficient (CF) is less than 1500, the area of the gap formed between the warp and the weft will be too large, and the resulting woven fabric will have Too high breathability (for example, greater than 5 ml / cm² · s) and insufficient water and sweat absorption properties and insufficient abrasion resistance. Similarly, if the cover factor (CF) of the woven fabric is greater than 350,000, the warp and weft yarns in the woven fabric will be in close contact with each other, and the woven fabric will have insufficient softness. And too high deflection resistance, so the feel of the woven fabric may become unsatisfactory and the abrasion resistance of the woven fabric may be insufficient. In the woven fabric with flat multi-filament yarns having a cloth covering factor of 15,000 to 10 3500 in the specific embodiment (1) of the present invention, the flat multi-filament yarns of the warp and / or weft yarns constituting the woven fabric , Flattened and spread laterally due to the squeezing pressure generated at the warp_weft crossing portion of the fabric, under which the respective flat yarns will contact each other at their flat periphery Slide it to make the flat yarn. In this flattening of the yarn 15, the area of the gap between the warp yarn and the weft yarn is reduced, so that the woven fabric produced has reduced air permeability. Therefore, the shuttle fabric which is a flat multi-filament yarn according to a specific embodiment of the present invention preferably has a low air permeability of 5 ml / cm² · s or less. — In a specific embodiment of the present invention, the flattening of the flat multi-filament yarn can cause the resulting woven fabric to have reduced flex resistance, increased softness, and good hand feeling. Similarly, in a specific embodiment ⑴ of the present invention, in the woven fabric, in the multi-filament yarns, each individual flat yarn has 3 or more edges on each side of the flat profile. The protrusions extending in the longitudinal direction of the periphery, and forming two or more necks between the protrusions 21 200402488, so that the periphery of the respective flat yarns is rough. Therefore, when the respective yarns in the yarns are brought into contact with each other (especially under the compression pressure generated at the intersection of the warp and weft yarns), the The contact area is relatively small, so the abrasion resistance between individual yarns is small. Therefore, the rough surroundings of these individual yarns contribute to the increased softness of the woven fabric produced. Furthermore, in the periphery of each individual filament, the necking extending in the longitudinal direction of the periphery does not (or substantially does not) approach, even when the periphery of the respective yarns contact each other. Therefore, water or sweat diffuses easily along the neck due to the capillary phenomenon, so the woven fabric 10 has excellent water and sweat absorption properties. The flat multi-filament yarn shuttle fabric of the specific embodiment (1) of the present invention has excellent soft hand feeling, high water absorption and sweat absorption properties, and high abrasion resistance, so it can be usefully used as a low air permeability textile material for different applications. Clothing, for example, men's and women's sportswear and uniforms, and folk costumes (folk costumes) 15 (native dresses), such as tabs, underwear, shirts, hat covers and umbrellas and Parasol fabric. In a specific embodiment (2) of the flat multi-filament yarn shuttle fabric of the present invention, the multi-filament yarns contain a matting agent, and the content thereof is 0.2% by mass or more, preferably 0.4 to 3.5 masses. %, More preferably from .0 to 2.5 quality, and the woven fabric 20 has a cover factor (CF) of 1300 to 3,000, preferably 1400 to 2500. The composition and type of the matting agent contained in the multi-filament yarn of the flat multi-filament yarn woven fabric of the specific embodiment (2) of the present invention are not limited as long as the target woven fabric of the present invention can be obtained. In general, the matting agent may include at least one type of fine inorganic particles, such as titanium dioxide and barium sulfate. 22 200402488 If the content of the matting agent is less than 0.2% by mass (based on the total mass of the multi-filament yarn), the multi-filament yarn produced will have an insufficient reflection coefficient, so the woven fabric cannot be made Satisfactory anti-perspective properties. It should be noted that if the content of the matting agent exceeds 7% by mass, the fiber-forming properties of the resulting polymer composition 5 may become unstable. If the woven fabric covering factor (CF) of the specific embodiment (2) of the present invention is less than 1300, the gap between the warp and weft yarns will be too large, and the resulting woven fabric will have unsatisfactory results. Anti-perspective nature. Similarly, if the cloth cover factor (CF) is greater than 3000, the resulting woven fabric will have insufficient softness and unsatisfactory feel. In the example where the woven fabric of the specific embodiment (2) of the present invention has a plain weave structure, the cover factor of the plain weave fabric is preferably from 1400 to 1800, more preferably from 15,000 to 1700. In the example where the woven fabric of the specific embodiment (2) of the present invention has a structure of 15 twill weaves, the cover factor (CF) of the produced twill weave fabric is preferably 1900 to 2400, more preferably 2000 to 2300. The number of twists of the multi-filament yarn that can be used for the woven fabric of the specific embodiment (2) of the present invention is not particularly limited as long as the target woven fabric of the present invention can be obtained. However, in order to fully guarantee the 20 degrees of freedom of the respective silk yarns in the yarn (relative to each other), the twist of the flat multi-straight yarn is preferably 0 to 1500 revolutions / meter, and more preferably 0 to 600 revolutions / meter. Still better number of turns / meter (in other words, no twist). 0 In the specific embodiment (2) of the present invention, the flat multi-filament yarn preferably has a degree of anti-permeability, which is in the L * a * b * color system '23 200402488 by the will The difference between the L * value (represented by l * w) of the woven fabric on the white board and the L * value (represented by L * b) of the woven fabric on the blackboard (by △ L (= L * WL * b) represents 15) or less, more preferably 10 to η. In practice, if the anti-see-through degree AL is greater than 15, the anti-see-through property of the woven fabric produced is insufficient. The flat multi-filament woven fabric of the specific embodiment (2) of the present invention preferably has a water absorption speed of 40 mm or more, more preferably 45 mm or more, and still more preferably 50 to 70 mm It can be measured according to JISL 1096-1998, 6.26.1, (2) Method B (Berrick Method). In practice, if the water absorption speed is less than 10 40 m², the woven fabric produced will have insufficient water absorption and sweat absorption properties. In the flat multi-filament yarn shuttle fabric of the specific embodiment (2) of the present invention, the cross-sectional profile of the respective yarns constituting the flat multi-filament yarn is flat. In this flat cross-sectional profile, two or more protrusions are formed on each side cross-section of the flat profile and two 15 or more neckings are formed between the protrusions. Therefore, the respective yarns which have come into contact with each other have low friction resistance with each other and can easily slide with each other. When a squeezing pressure is applied to the multi-filament yarn, the respective yarns can easily move relative to each other along the periphery of the contacts, so the multi-filament yarn is flattened and spread laterally. Similarly, the respective yarns are in close contact with each other at the flat peripheries, so that the gap between the yarns (which are arranged in the woven towel) is reduced, and the amount of light transmitted through the woven fabric is reduced. Will decrease. Similarly, the matting agent (the content of which is 0.2% by mass) contained in the respective yarns causes the light transmittance through the woven fabric to be reduced, and the light irradiated toward the woven fabric may be irregular. Reflected in the woven fabric. Furthermore, the numerous protrusions and neckings formed around the respective yarns by 200402488 will cause the surroundings of the respective yarns to be roughened to scatter the incident light and prevent the woven fabric from seeing through. In the intersecting portions of the warp and weft of the woven fabric, the flattening and spreading of the multi-filament yarns can cause the intersecting portions to become soft and the feel of the woven fabric to be soft. 5 Furthermore, the necking extending along the longitudinal axis of the respective straight filaments can cause capillary phenomena to the generated water and sweat, so that the resulting woven fabric has a high water absorption and sweat absorption speed. In other words, the flat multi-filament yarn shuttle fabric of the specific embodiment (2) of the present invention can be usefully used as a 10 textile material that requires high anti-perspective properties and water and sweat absorption properties, which can be used in, for example, shirts, sports Uniforms and uniforms. In a specific embodiment (3) of the flat multi-filament yarn shuttle fabric of the present invention, each of the multi-filament yarns of a man-made yarn contains a small content (0 to 0.02% by mass) of a matting agent, and The cover factor (CF) of the woven fabric ranges from 800 to 2000. 15 In the flat multi-filament yarn shuttle fabric of the specific embodiment (3) of the present invention, the content of the matting agent in the respective artificial yarns and threads is 0 to 0.2% by mass, and preferably 0 to 0.1. quality%. More preferably, no matting agent is included in these individual yarns. The matting agents that can be used in the present invention can be selected from conventional matting agents, such as ' titanium dioxide and sulfur. If the extinction content is more than ^% by mass, 20 In the preferred use of the woven fabric (for example, curtains) in the specific embodiment of the present invention, the woven fabric produced will have insufficient light transmittance, so it will cause Unsatisfactory brightening properties. In the woven fabric of the multi-filament yarn solution according to the specific embodiment of the present invention, 'the multi-filament yarn's check number is preferably ⑷face turn / meter rent, and more preferably ^ 25 200402488 200 turn / meter'. More preferably, there is no transfer. The cover factor (CF) of the flat multi-filament woven fabric of the specific embodiment (3) of the present invention ranges from 800 to 2000, preferably from 900 to 1800, and more preferably from 1,000 to 1800. 5 If the cloth surface coverage factor (CF) is less than 800, in the preferred application of the flat multi-filament yarn woven fabric (for example, curtains) in the specific embodiment (3) of the present invention, the warp and weft of the woven fabric The gap between them can be too large, and the resulting woven fabric can have insufficient anti-see-through properties. Similarly, if the cloth coverage factor is more than 2000, the resulting woven fabric will have insufficient lighting properties. The flat multi-filament yarn woven fabric of the specific embodiment (3) of the 10 I invention preferably has a light transmittance degree of 10 to 70%, more preferably 20 to 50%, which may be in accordance with JISL 105 -1987, 6.1. Method A, measured with 100000 1 exhaustion degree. The light transmittance (//) can be calculated by subtracting the light-blocking ratio (%) of the woven fabric. If the light transmittance is less than 10%, in the preferred 15-way use of the woven fabric (for example, curtains), The lighting properties of the produced woven fabrics will be insufficient. Similarly, if the light transmittance is more than 70%, the produced woven fabrics will have insufficient anti-perspective properties. Specific examples of the tree tree It is preferably non-colored or dyed to a bright or appropriate color. The type and amount of the dye used for dyeing can be established in consideration of the purpose and desired properties of the dyed woven fabric produced. @ 在 发明 的In the flat multi-filament yarn shuttle fabric of the specific embodiment (3), "Hey flat multi-filament yarns intersect in the warp and weft yarns of the shuttle fabric, The squeezing pressure generated in the section 26 200402488 force) 'These respective yarns are in close contact with each other at their flat periphery to form a uniform dense structure. In this dense structure, between the warp and weft yarns Small gaps reduce the amount of light passing through these gaps. The light in this gap will be diffracted in the small gap, and the 5 threads of light passing through the small gap adjacent to each other will interfere with each other to improve the anti-see-through effect of the woven fabric. Similarly, the multi-filament yarn The specific cross-sectional profile of the respective flat yarns in will cause the incident light to be irregularly reflected around the respective yarns, and the refraction of the light transmitted through the yarns will increase (as opposed to having flat Cross-sectional profile and provides a smooth surrounding yarn, yarn 10 with a circular cross-sectional profile, and yarn with a triangular cross-sectional profile.) Therefore, the resulting woven fabric has an excellent anti-see-through effect without Reduce its lighting properties. The flat multi-filament woven fabric of the specific embodiment (3) of the present invention has a good soft feel, low flex resistance, low air permeability, and high abrasion resistance, similar to the specific embodiment (1) and (2). 15 For the reasons mentioned above, the flat multi-filament woven fabric of the specific embodiment (3) of the present invention can be usefully used as an anti-see-through textile material in the interior , Such as curtains, rolls (Light-shielding material) and separator.
