Abstract
Description
本発明は、吸水性、紫外線遮蔽効果、防スケ性、およびソフトな風合を有する紡績糸およびそれを用いてなる織編物に関するものである。 The present invention relates to a spun yarn having water absorption, an ultraviolet shielding effect, anti-scaling properties, and a soft texture, and a woven or knitted fabric using the spun yarn.
従来よりスポーツ用途などで主にポリエステル素材を用いた吸汗・速乾素材の検討が行われており、吸水性を高めるために異型断面ポリエステル繊維が用いられている。例えば断面形状として３個以上の突起物を有し、異型度が１．８以上の異型ポリエステル短繊維を含有する紡績糸などが提案されている（特許文献１）。
しかしながら、特許文献１においては、異型原綿を用いているものの、単糸間で形成される空隙が少なく吸水性能が得られないという問題を有していた。
特許文献２には断面形状が三角断面を有するポリエステル短繊維と、単繊維繊度が三角断面ポリエステル短繊維の２倍以上で繊維断面が丸形状の丸断面ポリエステル短繊維とから主としてなる紡績糸が記載されている。この場合、三角断面短繊維と太繊度丸断面短繊維との組合せにより、これらの短繊維の間に空隙ができることにより、目的とする吸水性能、および太繊度短繊維による麻調の張腰を得ることができる。
しかし太繊度短繊維を含むが故に肌に直接触れる用途では、チクチク感があり、好ましくない形態を有するものであった。
夏場の清涼感素材として吸水速乾性とともに求められる機能として紫外線遮蔽、スケ感防止などが挙げられる。これらの機能を付与するため、特許文献３には白色顔料の含有量が異なる2種類のポリエステルからなる芯鞘型複合ポリエステルを含む紡績糸が提案されている。しかしながら、この紡績糸は、吸水速乾性を有するものではなかった。
特許文献４には、凹部を有しない断面形状からなる単フィラメントと凹部を有する断面形状の単フィラメントとを用いた複合糸であって、単フィラメント断面間に空隙を形成することで吸水性能を得るポリエステル混繊複合糸が提案されている。しかしながら、織編物にした際にフィラメント特有の粗硬感があり、また紫外線遮蔽効果を併せ持つには十分ではなかった。
Conventionally, studies have been made on sweat-absorbing and quick-drying materials mainly using polyester materials for sports applications, and atypical cross-section polyester fibers are used to increase water absorption. For example, a spun yarn containing three or more projections as a cross-sectional shape and containing atypical polyester staple fibers having a degree of atypia of 1.8 or more has been proposed (Patent Document 1).
However,
However, since it contains thick fine fibers, it has a tingling sensation in applications where it directly touches the skin and has an unfavorable form.
As a refreshing material in summer, the functions required of water absorption and quick drying include ultraviolet ray shielding and prevention of skate feeling. In order to impart these functions, Patent Document 3 proposes a spun yarn including a core-sheath type composite polyester composed of two types of polyesters having different white pigment contents. However, this spun yarn was not water-absorbing and quick-drying.
Patent Document 4 discloses a composite yarn using a single filament having a cross-sectional shape having no recess and a single filament having a cross-section having a recess, and obtains water absorption performance by forming a gap between the cross-sections of the single filament. Polyester mixed fiber composite yarn has been proposed. However, when it is made into a woven or knitted fabric, there is a rough feeling peculiar to filaments, and it is not sufficient to have an ultraviolet shielding effect.
本発明は、従来の技術では得られなかった吸水性、紫外線遮蔽効果、防スケ性の機能とソフトな風合とを兼ね備えた織編物およびそれに用いる紡績糸を提供することを課題とする。 It is an object of the present invention to provide a woven or knitted fabric having a water absorbing property, an ultraviolet shielding effect, an anti-scaling function, and a soft feel, and a spun yarn used therefor, which cannot be obtained by conventional techniques.
上述した目的を達成するため、本発明は、以下の構成を有する。
(1) 単繊維繊度が２デシテックス以下であり、断面形状が４個以上の凸部を有し、異型度が１．７〜４．０である異型ポリエステル短繊維と、前記異型ポリエステルの内接円直径以上、外接直径以下の直径を有する丸断面ポリエステル短繊維とから主としてなる紡績糸であって、紡績糸において前記異型ポリエステル短繊維を３０重量％以上含み、かつヨリ係数が３．０〜４．５であることを特徴とする紡績糸。
(2) セルロース系繊維を含む上記(1)に記載の紡績糸。
(3) 前記丸断面ポリエステル短繊維が芯鞘型複合ポリエステルであり、芯成分における酸化チタンの含有量が１．５重量％以上１０重量％以下、鞘成分における酸化チタンの含有量が０．５重量％以下であって、かつ芯成分が前記丸断面ポリエステル短繊維断面積において２５％〜７５％の割合を占めることを特徴とする上記(1)に記載の紡績糸。
(4) 上記(1)〜(3)のいずれかに記載の紡績糸を織編物中、４０重量％以上含むことを特徴とする織編物。
In order to achieve the above-described object, the present invention has the following configuration.
(1) Atypical polyester short fibers having a single fiber fineness of 2 decitex or less, a cross-sectional shape of 4 or more convex portions, and a profile degree of 1.7 to 4.0, and the inside of the profile polyester A spun yarn mainly comprising a round cross-section polyester short fiber having a diameter not less than a circle diameter and not more than a circumscribed diameter, wherein the spun yarn contains 30% by weight or more of the atypical polyester short fiber and has a twist coefficient of 3.0 to 4 A spun yarn characterized by being .5.
(2) The spun yarn according to (1) above, comprising cellulosic fibers.
(3) The short cross-section polyester short fiber is a core-sheath type composite polyester, the content of titanium oxide in the core component is 1.5% by weight or more and 10% by weight or less, and the content of titanium oxide in the sheath component is 0.5. The spun yarn according to the above (1), wherein the spun yarn is not more than% by weight and the core component occupies a ratio of 25% to 75% in the cross-sectional area of the round cross-section polyester short fiber.
(4) A woven or knitted fabric comprising the spun yarn according to any one of (1) to (3) above in an amount of 40% by weight or more in the woven or knitted fabric.
本発明により優れた吸水性能とソフトな風合いとを兼ね備えた紡績糸およびそれを用いてなる織編物を得ることができる。さらには、紫外線遮蔽効果、防スケ性の機能を併せ持つ紡績糸および織編物を提供することができる。 According to the present invention, it is possible to obtain a spun yarn having both excellent water absorption performance and soft texture, and a woven or knitted fabric using the spun yarn. Furthermore, it is possible to provide a spun yarn and a woven or knitted fabric having both an ultraviolet shielding effect and an anti-scaling function.
本発明の紡績糸に含まれる異型ポリエステル短繊維の単繊維繊度は、ソフト性、吸水性を両立し得る観点から２デシテックス以下の範囲であることが必要であり、紡糸安定性、および紡績時のカード通過性を考慮すると、１デシテックス以上であることが好ましい。
異型ポリエステル短繊維は断面形状として、４個以上の凸部を有し、異型度が１．７以上、４．０以下であることが必要である。凸部が４個未満の場合、繊維単糸間に形成される空隙が少ないため、毛細管現象による吸水性が得られないほか、紡績工程通過時に凸部の割れが生じ易い。更に異型度を１．７以上とすることによって、繊維単糸間の空隙を形成することができ、吸水性を付与できる。但しあまり異型度を大きくすると繊維の割れ、フィブリル化が生じ、紡績、製織時の工程通過性、製品の品位低下を招くため、４．０以下であることが好ましい。
本発明でいう異型度は以下の方法で求める。
異型度＝Ｌ１／Ｌ２
Ｌ１：繊維横断面の外接円の直径
Ｌ２：繊維横断面の内接円の直径
異型度を求める場合、短繊維中、任意に単繊維を５０本抽出し、それぞれ一箇所ずつ異形度を求め、その平均値を算出する。
また異型ポリエステル短繊維と混紡する丸断面ポリエステル短繊維の断面直径は、前記異型ポリエステルの内接円直径未満である場合、前記異型ポリエステルの凹部分に丸断面ポリエステル短繊維が入り易く空隙が少なくなり、目標とする吸水効果が得られない他、細繊度のため紡績工程中にネップなどの糸欠点に成り易いため好ましくない。また外接円直径を越える場合、太繊度であるが故に肌に直接触れる用途では、チクチク感がありソフト感が得られないほか、紡績糸を構成する繊維構成本数が減少し、糸均整度、糸強力の低下を招く。以上の理由から丸断面ポリエステル短繊維の断面直径は前記異型ポリエステルの内接円直径以上、外接円直径以下であることが必要である。
前記異型断面ポリエステル短繊維と丸断面ポリエステル短繊維が混紡され紡績糸となることで、フィラメント使いにはないランダムな配列となって空隙を有し、目標とする吸水効果が得られるのである。
異型ポリエステル短繊維は紡績糸中に３０重量％以上含まれることが必要である。３０重量％未満では前記異型ポリエステル短繊維と丸断面ポリエステルとの組合せから十分な空隙が得られない。３０重量％以上とすることで単繊維間に空隙が確保でき、その空隙を水が移動し易く毛細管現象による吸水性が得られる。
丸断面ポリエステル短繊維が紡績糸中に含まれる割合は異型ポリエステル短繊維と同重量％とするのが吸水性、紡績工程中の重量管理の点から好ましく、重量割合として、異型ポリエステル短繊維：丸断面ポリエステル短繊維＝４０〜６０：６０〜４０であることが好ましい。
本発明の紡績糸のヨリ係数は３．０〜４．５の範囲であることが必要である。ヨリ係数が３．０未満では十分な糸強力が得られず、紡績時の糸切れ、布帛にした際の強度低下を招き、また４．５を超えるとヨリ戻りによるビリが発生するほか、布帛にした際に粗硬感があり好ましくない。
また異型ポリエステル短繊維と混紡する丸断面ポリエステル短繊維として、芯成分の酸化チタンの含有量が１．５重量％以上１０重量％以下、鞘成分の酸化チタンの含有量が０．５重量％以下、かつ芯成分が繊維断面積の２５％〜７５％を占める芯鞘型複合ポリエステル短繊維を用いることにより、前述の吸水効果に加え優れた紫外線遮蔽効果のほか、防スケ性を付与することができる。
通常、酸化チタンを多く含むポリエステルが繊維表面に現れると風合いが粗硬になるため、本発明の目的である吸水性とソフト風合いを両立させるために混紡する丸断面ポリエステルとして用いた場合、異型断面ポリエステル短繊維の断面形状から由来する粗硬感と相乗してしまい好ましくない。
しかし前述の芯鞘型複合ポリエステル短繊維の表面、つまり鞘成分として酸化チタンの含有量が０．５重量％以下のポリエステルを用いると、布帛にした際に表面はソフトな風合いを保ちながら、酸化チタン含有量が１．５重量％以上１０重量％以下と鞘成分に対し比較的多い芯成分により紫外線遮蔽効果を得ることができる。
芯鞘型複合ポリエステル短繊維の芯成分ポリエステルの繊維横断面に占める面積割合は２５％未満であると十分な紫外線遮蔽効果が得られ難く、７５％を超えると短繊維製造工程の捲縮付与工程において繊維が座屈し難い傾向があるため２５％〜７５％の範囲が好ましい。
また本発明の紡績糸には、前記異型ポリエステル短繊維と丸断面ポリエステル短繊維の他に、綿、レーヨンなどのセルロース系繊維、あるいは他ポリエステル、ナイロン、アクリル繊維等を混紡しても良い。
The single fiber fineness of the atypical polyester short fiber contained in the spun yarn of the present invention is required to be in the range of 2 dtex or less from the viewpoint of achieving both softness and water absorption, spinning stability, and spinning Considering the card passing property, it is preferably 1 dtex or more.
The atypical polyester short fiber needs to have four or more convex portions as a cross-sectional shape, and the atypical degree should be 1.7 or more and 4.0 or less. When the number of convex portions is less than four, since there are few voids formed between the single fibers of the fiber, water absorption due to capillary action cannot be obtained, and the convex portions are likely to crack when passing through the spinning process. Further, when the degree of atypicality is 1.7 or more, voids between single fibers can be formed, and water absorption can be imparted. However, if the degree of atypicality is too large, fiber cracking and fibrillation will occur, leading to process passability during spinning and weaving, and deterioration of the product quality.
The degree of variant in the present invention is determined by the following method.
Atypical degree = L1 / L2
L1: Diameter of the circumscribed circle of the fiber cross section L2: When obtaining the degree of irregularity of the diameter of the inscribed circle of the fiber cross section, 50 single fibers are arbitrarily extracted from the short fibers, and the degree of irregularity is obtained one by one, The average value is calculated.
In addition, when the cross-sectional diameter of the round polyester short fiber blended with the irregular polyester short fiber is less than the inscribed circle diameter of the irregular polyester, the round polyester short fiber easily enters the concave portion of the irregular polyester, and voids are reduced. In addition, the desired water absorption effect cannot be obtained, and the fineness of the yarn tends to cause yarn defects such as a nep during the spinning process. Also, when the diameter exceeds the circumscribed circle diameter, it is thick and fine, so there is a tingling sensation and a soft feeling is not obtained, and the number of fibers constituting the spun yarn decreases, and the yarn uniformity, yarn It causes a drop in power. For the above reasons, the cross-sectional diameter of the round cross-section polyester short fiber needs to be not less than the inscribed circle diameter of the modified polyester and not more than the circumscribed circle diameter.
By blending the irregular cross-section polyester short fiber and the round cross-section polyester short fiber into a spun yarn, it becomes a random arrangement not used by the filament, has voids, and a target water absorption effect is obtained.
The atypical polyester staple fiber needs to be contained in the spun yarn by 30% by weight or more. If it is less than 30% by weight, sufficient voids cannot be obtained from the combination of the atypical polyester short fiber and the round cross-section polyester. By setting the content to 30% by weight or more, voids can be secured between the single fibers, and water can easily move through the voids to obtain water absorption by capillary action.
The ratio of the short cross-section polyester short fibers contained in the spun yarn is preferably the same weight% as the atypical polyester short fibers in terms of water absorption and weight management during the spinning process. It is preferable that it is cross-sectional polyester short fiber = 40-60: 60-40.
The twist coefficient of the spun yarn of the present invention needs to be in the range of 3.0 to 4.5. If the twist coefficient is less than 3.0, sufficient yarn strength cannot be obtained, resulting in yarn breakage during spinning and a decrease in strength when made into a fabric. When it is made, there is a feeling of coarseness, which is not preferable.
Also, as a round cross-section polyester short fiber blended with atypical polyester short fiber, the content of titanium oxide as a core component is 1.5% by weight or more and 10% by weight or less, and the content of titanium oxide as a sheath component is 0.5% by weight or less By using core-sheath type composite polyester short fibers in which the core component occupies 25% to 75% of the fiber cross-sectional area, in addition to the above-mentioned water absorption effect, it can impart an anti-scaling property. it can.
Usually, when a polyester containing a large amount of titanium oxide appears on the fiber surface, the texture becomes coarse and hard, so when used as a round cross-section polyester that is blended to achieve both water absorption and soft texture, which is the object of the present invention, This is unfavorable because it synergizes with the rough and hard feeling derived from the cross-sectional shape of the polyester short fiber.
However, when the surface of the core-sheath-type composite polyester short fiber, that is, polyester having a titanium oxide content of 0.5% by weight or less is used as the sheath component, the surface is oxidized while maintaining a soft texture. An ultraviolet shielding effect can be obtained by the core component having a titanium content of 1.5 wt% or more and 10 wt% or less and relatively large with respect to the sheath component.
When the area ratio of the core-sheath type composite polyester short fiber in the fiber cross section of the core component polyester is less than 25%, it is difficult to obtain a sufficient ultraviolet shielding effect, and when it exceeds 75%, the crimping step of the short fiber manufacturing process is difficult. In this case, the range of 25% to 75% is preferable.
Further, the spun yarn of the present invention may be blended with cellulosic fibers such as cotton and rayon, other polyester, nylon, acrylic fiber, etc., in addition to the above-mentioned atypical polyester short fiber and round cross-section polyester short fiber.
本発明の紡績糸は、前記異型ポリエステル短繊維と丸断面ポリエステル短繊維とを用いて通常の紡績方法により製造することができ、リング精紡機、空気精紡機等を用いることができる。混紡方法も前記異型ポリエステル短繊維と丸断面ポリエステル短繊維の２種類の混紡や本発明の混紡率範囲内で他繊維と混紡することも可能である。紡績糸の番手は特に限定されない。 The spun yarn of the present invention can be produced by an ordinary spinning method using the atypical polyester short fiber and the round cross-section polyester short fiber, and a ring spinning machine, an air spinning machine, or the like can be used. As for the blending method, it is possible to blend with other fibers within the blending rate range of the present invention, or two types of blended polyester short fibers and round cross-section polyester short fibers. The count of the spun yarn is not particularly limited.
本発明の織編物は、本発明の紡績糸を１００％用いた織編物としても良いが、少なくとも４０重量％以上含有されていることが好ましい。４０重量％未満では本発明の異型断面と丸断面形状の組合せによる吸水性効果が得られにくい。また６０重量％未満の範囲で、本発明の紡績糸に他の紡績糸、フィラメント等を交織、交編することが可能である。 The woven or knitted fabric of the present invention may be a woven or knitted fabric using 100% of the spun yarn of the present invention, but is preferably contained at least 40% by weight or more. If it is less than 40% by weight, it is difficult to obtain the water-absorbing effect due to the combination of the modified cross section and the round cross section of the present invention. Further, in the range of less than 60% by weight, other spun yarns, filaments, and the like can be woven or knitted into the spun yarn of the present invention.
本発明の織編物は、吸水性とソフトな風合いとを兼ね備えているため、ドレスシャツ、ブラウス、パンツ、ユニフォーム等として好適に用いることができる。 Since the woven or knitted fabric of the present invention has both water absorption and soft texture, it can be suitably used as a dress shirt, blouse, pants, uniform and the like.

Hereinafter, the present invention will be described in detail with reference to examples.

The diameter of the circle inscribed in the polyester short fiber was 6.8 μm, the diameter of the circumscribed circle was 12 μm, and the degree of deformity was 1.76.
On the other hand, using 1.45 dtex, 10.6 μm diameter, 38 mm fiber length polyester short fiber as the round cross-section polyester short fiber, blended with the atypical polyester short fiber obtained above at a ratio of 50:50 (weight ratio), A spun yarn with an English cotton count of 45 s was obtained with a twist coefficient of K = 3.5.
This spun yarn was used for warp and width, and a plain fabric having a warp density of 110 / 2.54 cm and a warp density of 76 / 2.54 cm was woven with an air jet loom, and this fabric was dyed at 130 ° C.

As for the texture, a sensory evaluation was performed by 10 people as a soft feeling.
In addition, using an “ultraviolet ray shielding rate” spectrophotometer (Shimadzu Corporation), the sample was irradiated with ultraviolet rays to measure the amount of transmission between 280 and 400 nm, and the ultraviolet ray shielding rate was calculated from the following equation.
UV shielding rate (%) = 1−A / B × 100
A: Sample transmission amount (280 to 400 nm)
B: Transmission amount when not sampled (280 to 400 nm)
In addition, the evaluation of anti-scaling property was carried out using a spectrophotometer (Minolta M-3600d), measuring each L value (reflectance) with a standard white board and standard blackboard as the background of the sample fabric, and as anti-skel value (%) Obtained by the following equation.
Anti-scaling degree (%) = 100− (Lfw−Lfb) / (Lw−Lb) × 100
Lw: L value of the standard white board without the sample fabric Lb: L value of the standard blackboard without the sample fabric Lfw: L value when the sample fabric is placed on the standard white board Lfb: Sample fabric of the standard blackboard L value when placed on top Example 2
Using the die shown in FIG. 3, an odd-shaped polyester short fiber having a cross-sectional shape shown in FIG. 4, a single yarn fineness of 1.65 dtex, and a fiber length of 38 mm and four convex portions was obtained. The inner diameter of the circle inscribed in this square polyester short fiber was 4.7 μm, the diameter of the circumscribed circle was 12 μm, and the degree of deformity was 2.55.
A plain woven fabric was woven in the same manner as in Example 1 except that this modified polyester was used.

Then, after drawing at a natural draw ratio in a bath solution at 90 ° C., it is passed through a stuffer box to give crimps necessary for spinning short fibers, subjected to relaxation heat treatment at 90 ° C., and a 38 mm fiber with a cutter. A core-sheath composite short fiber having a cross-sectional shape shown in FIG. 5 having a short fiber fineness of 1.7 dtex and a diameter of 11.0 μm was obtained. In FIG. 5, 1 shows a sheath component and 2 shows a new component.
The round cross-section polyester and the atypical polyester short fiber described in Example 2 were blended at a ratio of 50:50 (weight ratio) to obtain a spun yarn having an English cotton count of 45 s with a twist coefficient of K = 3.5. . As a result of weaving a plain woven fabric in the same manner as in Example 2 and evaluating water absorption and texture, good water absorption performance was obtained, and as a result of measuring the ultraviolet shielding rate, the ultraviolet shielding rate was as high as 94.96%. there were. Further, the degree of anti-scaling was as high as 87.73%.
Comparative Example 1
In Example 1, a plain woven fabric was woven in the same manner as in Example 1 except that the round cross-section polyester short fiber to be blended was 4.4 dtex, the diameter was 18.6 μm, and the fiber length was 38 mm. evaluated.
Since the texture of the round polyester short fibers is 4.4 dtex and thick, the texture is rough and hard when it touches the skin, and the water absorption performance is inferior to that of Examples 1 and 2. .
Comparative Example 2
A plain woven fabric was woven in the same manner as in Example 1 except that the round cross-section polyester short fibers to be blended were 0.6 dtex, diameter 6.0 μm, and fiber length 38 mm. The water absorption and texture were evaluated in the same manner as in Example 1. In the spinning process, generation of a nep was observed when passing through the card process of 0.6 dtex round cross-section polyester short fibers. The texture was soft because the round cross-section polyester short fibers were fine, but the water absorption performance was inferior to that of Example 1, and the fabric surface was inferior in quality with noticeable yarn defects such as nep and slab.
Comparative Example 3
In Example 1, a plain woven fabric was woven in the same manner as in Example 1 except that the blend ratio of the atypical polyester short fiber and the round cross-section polyester short fiber was 15:85 by weight.
Although the texture was soft, the water absorption performance was inferior to that of Example 1.
Table 1 shows the results of evaluating the water absorption, texture, ultraviolet shielding rate, and anti-scaling degree of the plain fabrics after dyeing and processing obtained in Examples 1, 2, and 3 and Comparative Examples 1, 2, and 3.
本技術により吸水性およびソフトな風合いを有する紡績糸およびそれを用いてなる織編物を提供することができる。 According to the present technology, it is possible to provide a spun yarn having water absorption and a soft texture and a woven or knitted fabric using the spun yarn.
