- the drawn yarn obtained was passed through a preheating roller heated to 70 to 110 ° C. at a speed of 500 to 1400 m / min and a non-contact heater set to 170 to 240 ° C. It can be obtained by applying a heat set at a draw ratio (a relaxed heat set at a draw ratio of 1 or less).
- the polyester filament yarn Y ′ (which may be simply referred to as the filament yarn Y ′), which is the other component constituting the blended yarn of the present invention, is mainly subjected to a load in the elongation direction and is morphologically stable and post-processed.
- the elongation (ELB) needs to be 40% or less, preferably 30% or less
- the elongation rigidity (EMB) is 7.85 GPa (800 kg / mm 2 ) or more, preferably Needs to be 8.83 to 14.7 GPa (900 to 1500 kg / mm 2 ).
- the boiling water shrinkage (BWSB) needs to be 5% or more, preferably 7 to 20%.
- the thermal stress (TSB) at 160 ° C. is 0.88 mN / dtex (100 mg / dtex) or more, preferably 1.76 mN. / Dtex (200 mg / dtex) or more.
- the filament yarn Y ′ having such characteristics may be appropriately adjusted, for example, when the unstretched fiber made of the polyester is stretched.
- the elongation and rigidity may be adjusted by the draw ratio, and the boiling water shrinkage may be adjusted by the heat setting conditions at the time of drawing.
- the thermal stress can be adjusted by the draw ratio, the heating temperature during drawing, and the spinning speed of the undrawn fiber. However, if the spinning take-up speed is too high, the thermal stress after drawing may not be increased. Therefore, it is preferable to draw an undrawn fiber having a low spinning speed of 2500 m / min or less, preferably 1700 m / min or less. .
- a third component is copolymerized with polyester. For example, when an isophthalic acid component is copolymerized, one having a high shrinkage property can be easily obtained.
- the mixed yarn of the present invention needs to be entangled and mixed with the polyester filament yarn Y ′ after the heat treatment of the antistatic polyester filament yarn X ′.
- the reason for this is that the physical properties of the polyester filament yarn X ′ change due to heat treatment, stretching, twisting, etc. in the false twist crimping process, the elongation decreases, the thermal stress increases, and the elastic recovery rate improves.
- polyester filament yarn X If the polyester filament yarn X 'loses its property of being stretched or is crimped, it will become entangled with the adjacent yarn or resistance will increase, and when it is made into a fabric such as a woven fabric, It is presumed that the position of the thread that has been misaligned at the position becomes difficult to return to its original position and wrinkles are likely to occur.
- the air injection direction may be applied in the direction perpendicular to the yarn or along the traveling direction of the yarn, but according to the former, a product with relatively high gloss is obtained, On the other hand, according to the latter, a relatively soft product can be obtained.
- an overfeed difference may be provided between the polyester filament yarn X ′ and the polyester filament yarn Y ′, and air composite processing may be performed. However, if too much difference is provided, many loops are likely to occur. Almost the same overfeed rate is adopted.
- the composite ratio (mixing ratio) of the polyester filament yarn X ′ and the polyester filament yarn Y ′ needs to be 45/55 to 70/30 by weight ratio of the polyester filament yarn X ′ and the polyester filament yarn Y ′. .
- the weight ratio of the polyester filament yarn X ′ and the polyester filament yarn Y ′ is particularly preferably 55/45 to 70/30.
- the polyester filament yarn X ′ and the polyester filament yarn Y ′ have been described by taking one yarn as an example, but of course, two or more yarns may be used. Any number of yarns may be used as long as they satisfy the physical properties.
- metal plated fibers or carbon particle-mixed fibers may be combined to impart conductivity.
- the combined use rate is desirably 30% at most.
- the antistatic core-sheath type polyester fiber used in the first to fourth inventions of the present application has a fiber cross section having a protrusion coefficient defined by the following formula of 0.3 to 0.7 in the cross section of the single fiber. It is preferable that there are 3 to 8 fin portions protruding outward from the core portion.
- the polyester multi-fiber of the present invention having such characteristics and cross-sectional shape can withstand the impact received during the drawing false twisting process, and the yarn breakage (processing) during the drawing false twisting process even if the drawing false twisting is performed under normal conditions.
- the yarn can be drawn with little occurrence of yarn breakage and fluff, and the polyoxyalkylene glycol antistatic agent is sufficiently elongated and streaks in the fiber axis direction, so that the antistatic property is good.
- the obtained drawn false twisted yarn also has a fiber cross section in which the degree of flatness of the fiber cross section is appropriately dispersed in the fiber axis direction, the fiber cross section is not uniform in the fiber axis direction, and a fiber aggregate having a large interfiber gap is formed. It forms, and brings about the effect of water absorption / quick drying performance and improvement of washing durability of the performance. Furthermore, the fiber assembly in which the degree of flatness of the fiber cross section is appropriately dispersed in the fiber axis direction also has the performance of bringing a natural dry feeling in the fabric.
- the antistatic core-sheath polyester fiber has good water absorption performance, antistatic properties and process stability.
- hydrophilic polyoxyalkylene glycols and ionic compounds that are used as antistatic agents more than capillarity water absorption due to protrusions of specific shapes are used as core antistatic agents.
- the water absorption is improved, and the resistance between fibers is reduced at the time of spinning drawing, especially at the time of drawing, so that the antistatic agent is uniformly stretched in the fiber axis direction to have an appropriate aspect ratio and generation of fluff. It is presumed that the process stability is good with less.
- the protrusion coefficient of the single fiber cross-sectional shape of the antistatic core-sheath polyester fiber is 0.3 to 0.7, more preferably 0.4 to 0.6. It is necessary to have a shape in which the number of fin portions (1 in FIG. 5) protruding outward from the fiber cross-section core portion is 3 to 8, preferably 4 to 6.
- the fin portion having a projection coefficient of less than 0.3 does not have a function of forming sufficient capillary voids in the fiber cross section after drawing false twisting, and cannot exhibit water absorption and quick drying performance. Further, such a short fin portion has a tendency to reduce the washing durability of the treatment agent because the anchor effect when the water absorption treatment agent is applied to the fabric is reduced. Also, the texture of the fabric is flat paper-like. On the other hand, the fin portion having a projection coefficient exceeding 0.7 is likely to concentrate the processing tension on the fin portion at the time of drawing false twisting. Water absorption performance is insufficient. Further, yarn breakage (processed yarn) and fluff frequently occur in the drawing false twisting process.
- the fin portion has a protrusion coefficient of 0.3 to 0.7, if the number of the fin portions is 1 to 2 in the single fiber cross section, only one fiber cross section closed inside is formed. As a result, there is no sufficient capillary action and water absorption performance is insufficient. Also, the texture of the fabric is flat paper-like.
- the number exceeds eight processing tension concentration on the fin portion occurs at the time of drawing false twisting, resulting in partial breakage of the fiber cross section, resulting in insufficient capillary formation and insufficient water absorption performance. Become. Further, yarn breakage (processed yarn) and fluff frequently occur in the drawing false twisting process. Note that there may be more than eight fin portions having a protrusion coefficient of less than 0.3.
- the antistatic core-sheath polyester multifiber of the present invention described above can be prepared by adjusting the discharge holes of a known core-sheath compound spinning machine.

- the length of the tip of the fin portion forming discharge hole (b2 in FIG. 6) and the like from the center point of the circular discharge hole the protrusion coefficient of the fiber cross section becomes 0.3 to 0.7. It can be set arbitrarily.
- the protrusion coefficient of the fiber cross section can be controlled to some extent by changing the temperature of the spin block and / or the cooling air volume.
- the antistatic core-sheath polyester fiber used in the first to fourth inventions of the present application has a flat cross section perpendicular to the length direction of the single yarn, and 3 to 3 of the round cross section single yarn in the longitudinal direction. It is necessary that six pieces have a joined shape and a constricted portion is formed at the joined portion.
- the constricted portion is a portion where the length of the short side is shortened as schematically shown in FIG.
- the depth of the concave portion is 1.05 or more (preferably 1.1 or more) as the ratio B / C of the maximum value (B) and the minimum value (C) of the length of the short side.
- the depth is preferred.
- the recessed part may be formed only in one side part.
- the number of the constricted portions needs to be two or more. If the constricted portion is one or less, sufficient irregular reflection of light and refraction of transmitted light cannot be obtained at the constricted portion, and satisfactory visibility can be obtained. It is not preferable because it is not.
- the number of the constricted portions is not particularly limited as long as it is 2 or more, but 3 to 5 is appropriate in consideration of the yarn forming property.
- FIG. 8 illustrates the case where there are two constrictions.
- the antistatic core-sheath polyester fiber has a special flat cross-sectional shape, when woven, it has a structure that is densely and widely spread by contact pressure at the fabric texture point. As a result, the gap formed by the warp and the weft is reduced, and the amount of light passing through the gap is reduced. At that time, a very small amount of passing light passing through the gap is diffracted, and adjacent passing light interferes with each other, thereby obtaining an excellent visual recognition effect.
- the cross-sectional shape of the filament is a flat cross-sectional shape having a specific constricted portion and the content of the matting agent is not more than a specific amount, flat flat cross-sectional yarns, round cross-sectional yarns, triangular cross-sectional yarns of the same fineness Compared with the above, irregular reflection of light and refraction of transmitted light that passes through the filament are increased, and an excellent anti-visual effect can be obtained without impairing the daylighting property.
- the core-sheath polyester flat cross-section fiber has a wide structure, the bending rigidity is lowered and a soft texture is added. Furthermore, at the fabric texture point, the constricted part (concave part) is less likely to come into contact with the other thread, so the friction between the warp and the weft is reduced, and it is possible to obtain a softer texture than that having a flat flat shape. become.

a1:繊維断面内面壁の内接円中心からフィン部頂点までの長さ
b1:繊維断面内面壁の内接円の半径(コアー部外挿内接円)
このような特性と断面形状を有する本発明のポリエステルマルチ繊維は、延伸仮撚加工時に受ける衝撃に耐え、通常の条件下で延伸仮撚を行っても、延伸仮撚加工時の糸切れ(加工断糸)および毛羽の発生が少なく延伸でき、ポリオキシアルキレングリコール系制電剤が十分に繊維軸方向に細長く筋状に存在するようになるので制電性が良好である。また得られる延伸仮撚加工糸も、その繊維横断面扁平度合いが繊維軸方向に適度に分散し、繊維軸方向に一様で無い繊維断面をなしており、繊維間空隙が大きな繊維集合体を形成するものとなり、吸水・速乾性能および該性能の洗濯耐久性向上の効果をもたらす。さらに、繊維断面扁平度合いが繊維軸方向に適度に分散する繊維集合体は、布帛での自然なドライ感をもたらすという性能も合わせ持っている。
ものとなる。一方、突起係数が0.7を越えるフィン部は、延伸仮撚加工時、該フィン部に加工張力が集中しやすいため、繊維断面の部分的破壊が発生して十分な毛細管形成がなされなくなり、吸水性能が不十分となる。また、延伸仮撚工程での糸切れ(加工断糸)や毛羽も頻発する。
加工張力集中が発生し、繊維断面の部分的破壊が起こり、十分な毛細管形成がなされなくなり、吸水性能が不十分となる。また、延伸仮撚工程での糸切れ(加工断糸)や毛羽が頻発する。なお、突起係数が0.3未満のフィン部は8個を超えて存在しても良い。
通常の丸断面単糸、或いは丸断面単糸2個が接合した形状の場合には、織物中の芯鞘型ポリエステル扁平断面繊維がワイドに広がった集合形態を形成し難くなり、経糸と緯糸とで形成される空隙(組織空隙)が大きくなり、その結果、該空隙から光が通過し、十分な防視認性を得ることができない恐れがあり好ましくない。逆に、7個を越えると、製糸性が困難となるため好ましくない。
