〔産業上の利用分野〕
本発明はワキシー感が少なくかつザラツキ感が少なく、
適度なハリ腰の感性に優れた新規な風合と嵩高を有する
ポリエステルマルチフィラメントに係わる。[Detailed description of the invention] [Industrial application field] The present invention has less waxy feeling and less rough feeling.
The present invention relates to a polyester multifilament that has a novel texture and bulk that has an excellent sense of firmness and elasticity.
ポリエステル繊維は強度が高く、耐熱性及びイーシイケ
ア性に優れる等優れた特性を有するため広く衣料分野で
利用され曵いろが、合成繊維特有のワキシー感が強い問
題があり、その改善のため主として繊維断面を円型断面
から多角断面或は多葉断面とする手法が知られており、
ワキシー感の改善にはそれなりの効果がある。Polyester fibers are widely used in the clothing field because they have excellent properties such as high strength, excellent heat resistance, and easy care. There are known methods to change a circular cross section to a polygonal or multilobal cross section.
It has some effect on improving the feeling of waxiness.
しかし、多角断面化することによってザラツキ感の強い
手ざわり感となり好まれず多葉断面化するとザラツキ感
と同時に硬い風合となる問題があった。However, the polygonal cross-section gives the material a strong rough texture, which is not preferred, and the multi-lobed cross-section gives the material a rough and hard texture.
本発明はワキシー感が少なくかつザラツキ感の少ない適
度なハリ腰の感性に優れた新規な風合と嵩高性を有する
ポリエステルマルチフィラメントを提供するものである
。The present invention provides a polyester multifilament having a novel texture and bulkiness that is less waxy, less rough, and has a moderate firmness.
本発明は、単繊維繊度が5.0デニール以下、単繊維横
断面内接円の直径(D、)と単繊維横断面(Wは単繊維
横断面系部の幅)力″−0.75以上であって、隣り合
う二葉間の角度θが等角度のフィラメントが80%以下
、異なる角度のフィラメントが20%以上からなる多葉
断面ポリエステルマルチフィラメントである。In the present invention, the single fiber fineness is 5.0 denier or less, the diameter (D, ) of the inscribed circle of the single fiber cross section and the force of the single fiber cross section (W is the width of the single fiber cross section) -0.75 The above is a multi-lobed cross-sectional polyester multifilament in which 80% or less of the filaments have the same angle θ between two adjacent leaves, and 20% or more of the filaments have different angles.
本発明者等は、多葉断面ポリエステルマルチフィラメン
トにおいて、ワキシー感、ザラツキ感が少なく、しかも
適度なハリ腰の感性に優れた新規な風合と嵩高性を得る
ため条件について合う二葉間の角度が全フィラメントに
おいて等角度であるために織編物となったとき、布帛表
面に東部の突出し密度が高くなりすぎたり、硬い風合と
なりザラツキ感が問題となっていたことが判明した。The present inventors have developed a polyester multifilament with a multi-leaf cross section that has a novel texture and bulkiness that is less waxy and rough, and has a moderate firmness. It was discovered that because all the filaments were at equal angles, when the fabric was made into a woven or knitted fabric, the density of the eastern part of the fabric surface would be too high, resulting in a hard texture and roughness.
例えば単繊維繊度d/xが5.0デニールを越えると衣
料用として感性のある風合を狙う場合硬以下では硬い風
合となりザラツキ感も強すぎるとなる。For example, if the single fiber fineness d/x exceeds 5.0 denier, when aiming for a sensitive feel for clothing, if it is less than hard, the texture will be hard and the roughness will be too strong.
間の角度が等角度の場合やはりザラツキ感が強く硬い風
合となる。この場合等角度のフィラメントが80%以下
で異なる角度のフィラメントが20%以上とするとザラ
ツキ感、硬さが減少し適度となるのである。更に異なる
形の多葉断面の混繊となり、繊維間空隙が大きくなり嵩
高性が増加する。If the angles between the two are equal, the texture will be very rough and hard. In this case, if the filaments at equal angles are 80% or less and the filaments at different angles are at least 20%, the roughness and hardness will decrease and become appropriate. Furthermore, the fibers are mixed with multi-lobed cross sections of different shapes, and the inter-fiber voids become larger, increasing the bulkiness.

ルとは、ポリエチレンテレフタレートのみならず共重合
ポリエステル或は各種の添加物を含有し【もよい。The shape of the eastern part of the filament having a multilobal cross section in the present invention is not limited to the examples shown in FIGS. 1, 2, and 3, but may be any shape. Moreover, polyester may contain not only polyethylene terephthalate but also copolymerized polyester or various additives.
又、多葉断面の東部の数は3個以上であり、マルチフィ
ラメントを形成する各フィラメントの東部数は同一でも
よく異なってもよい。Further, the number of eastern parts of the multifilament cross section is three or more, and the number of eastern parts of each filament forming the multifilament may be the same or different.

糸したHOY等紡糸延伸手法に限定されない。As shown in Figures 4, 5, and 6, the number of holes at the spinneret with equal angles between two adjacent leaves is 80% or less, and the number of holes at different angles is at least 20%. It is obtained by mixing the polyester in a spinneret, melt-spinning and drawing the polyester so that d/l becomes 5.0 denier or less. Further, a method in which spinning and drawing are directly connected may be used, and the method is not limited to spinning and drawing methods such as so-called high-speed spun partially oriented yarn (POY), and even high-speed spinning HOY.

来る。In addition, a multifilament consisting only of filaments with equal angles between two adjacent leaves is spun using a spinneret having a hole shape as shown in FIG.
If the twist coefficient is 0 or less, the twist coefficient is 1500 or more (twist coefficient = T4 T
: When twisting is applied (number of twists/m), D2 denier), the deformation force of the twist is applied, and even though the angle between two adjacent leaves is equal, the eastern part is deformed and the angle between two adjacent leaves changes. Filaments with different values come out. At this time, 80% of the filaments are filaments with equal angles between two adjacent leaves, and 20% are filaments with different angles, so the twist coefficient of K needs to be 1500 or more, and as the twist coefficient increases further, the filaments with equal angles 80% or less, filaments with different angles account for 20% or more, and the angle θ of each filament of the filaments with different angles also varies, resulting in a rich variety.
尚本発明の多葉断面ポリエステルマルチフィラメントは
、アルカリ減量加工をすると東部の先端部分よりも葉部
根元の部分方が減量速度が早いため根元の部分の方が多
く減量され、根元の部分が先端部より東部の幅が細くな
り、織編物の表面に突出している葉を手でされったとき
に東部を押し曲げる抗力が小さくなりザラツキ感を少な
くする効果がある。In addition, when the multi-lobed cross-section polyester multifilament of the present invention is subjected to alkali weight loss processing, the weight loss rate is faster at the leaf root portion than at the eastern tip portion, so the root portion loses more weight than the tip portion, and the root portion loses more weight than the tip portion. The width of the eastern part is narrower than that of the other parts, and when the leaves protruding from the surface of the woven or knitted material are touched by hand, the drag that pushes and bends the eastern part is reduced, which has the effect of reducing the roughness.
このアルカリ減量速度の差は葉部先端部の方が紡糸段階
での分子配向度が高く、これを延伸した後もその傾向が
残り、分子配向度の低い東部の根元の部分が減量速度が
早くなるものと推察される。This difference in alkali weight loss rate is due to the fact that the tip of the leaf has a higher degree of molecular orientation during the spinning stage, and this tendency remains even after drawing, and the weight loss rate is faster in the eastern root part, where the degree of molecular orientation is lower. It is assumed that this will happen.
以下実施例を示す。 Examples are shown below.

It is shown in the figure (after alkali reduction processing). As is clear from the comparison between the two figures, it can be seen that due to the alkali weight reduction process, the eastern root area has been reduced in weight more than the tip of the leaf. Therefore, the roughness is improved.
