【発明の属する技術分野】
本発明は、織編物に関するものであり、さらに詳しくは、捲縮糸の持つふくらみ感、ストレッチ性、軽量性と、非捲縮糸の持つ表面タッチに加え、双方の相乗効果による繊細な表面感を兼ね備えた織編物に関するものである。
【０００２】
【従来の技術】
織編物にふくらみ感を付与する方法は種々提案されている。たとえば、混繊糸を構成する糸条の収縮差を利用した異収縮混繊糸を用いる方法がある。異収縮混繊糸を用いた織編物は、染色加工時の受熱により糸長差を生じ、収縮率の低い糸条が織編物の表面に浮き出る形となり、ふくらみ感を付与することができる。しかしながら、この方法では、十分な糸長差を得るためには収縮の大なる糸条の収縮率を大きくする必要があり、このため風合いが硬くなるという欠点を有している。
【０００３】
この欠点を解消する方法として、特開平７−３１６９３９号公報には、芯糸に熱処理により収縮する糸条を、鞘糸に自発伸長する糸条を用いた混繊糸が提案され、一応の効果を奏している。しかしながら、自発伸長を示す糸条は、伸度が高く、強度が低いことから抗ピリングや抗スナッギング性に劣るという欠点を有しており、また織物においてはストレッチ性に乏しいものであった。
【０００４】
一方、古くから織編物にふくらみ感とストレッチ性を付与する方法として、仮撚加工糸を使用する方法があるが、この方法では、得られる織編物の表面タッチが硬く、合成繊維特有のがさついた風合いとなる欠点を有している。この欠点を解消するために、特開昭５９−１６３４３３号公報には先撚り仮撚加工糸が提案されているが、先撚を施した糸条は、取り扱いが難しく、またコストが高くなるという欠点を有している。
【０００５】
【発明が解決しようとする課題】
本発明は、このような状況を鑑みて行われたものであり、捲縮糸の持つふくらみ感、ストレッチ性、軽量性と、非捲縮糸の持つ表面タッチに加えて、双方の相乗効果による繊細な表面感を兼ね備えた織編物を提供することを技術的な課題とするものである。
【０００６】
【課題を解決するための手段】
本発明は、上記の課題を解決するために、次の構成を有するものである。
（イ）少なくとも１本のポリエステルマルチフィラメント捲縮糸Ａと少なくとも１本のポリエステルマルチフィラメント非捲縮糸Ｂとからなり、下記式（１）、（２）を満足し、かつ、交絡度が６０〜１００個／ｍ、非捲縮糸Ｂの割合が３０質量％以下であるポリエステル複合糸を製編織、染色して得られる織編物であって、非捲縮糸Ｂは捲縮糸Ａに比べて糸長が１〜５％大きく、かつ、非捲縮糸Ｂが織編物の表面に浮き出た構造であることを特徴とする織編物。
ただし、
ａ：捲縮糸Ａの糸長に対する非捲縮糸Ｂの糸長の割合
ｘ：捲縮糸Ａの熱水収縮率（％）
ｙ：非捲縮糸Ｂの熱水収縮率（％）
（ロ）非捲縮糸Ｂの強度が３．０ｃＮ／ｄｔｅｘ以上であることを特徴とする上記（イ）記載の織編物
【０００７】
【発明の実施形態】
以下、本発明について詳細に説明する。
本発明に係るポリエステル複合糸は、第１の要件として捲縮糸Ａと非捲縮糸Ｂの熱処理後の糸長の関係を示す前記（１）式を満足することが必要である。すなわち、〔（100 −ｙ）ａ−（100 −ｘ）〕／（100 −ｘ）の値は0.01〜0.05であることが必要であり、この値が0.01未満になると、織編物にしたとき非捲縮糸Ｂが表面に出る割合が低く、捲縮糸特有の硬い表面タッチになり、加えて視覚的にも単調な表面感となる。一方、前記の数値が０．０５を超えると、非捲縮糸Ｂが織編物表面に浮き出しすぎるため、抗スナッギング性が著しく低下するので、好ましくは０．０３以下とすることが必要である。
【０００８】
第２の要件は、前記（２）式のように捲縮糸Ａの糸長に対する非捲縮糸Ｂの糸長の割合ａが０．９０〜１．０２の範囲であることが必要である。ａが０．９０未満になると、後述するように非捲縮糸Ｂの割合が３０質量％以下の場合、整経等その後の加工工程で受ける張力により非捲縮糸Ｂが伸ばされやすく、単糸切れが生じやすくなる。また、ａが１．０２を超えると、低張力下での複合糸の形態は、捲縮糸Ａの顕在捲縮により非捲縮糸Ｂが交絡間に浮き出した提灯状を呈するものとなり、製織時に経糸毛羽の原因になるなど、その後の加工工程での取り扱いが困難となる。
【０００９】
第３の要件として、本発明の複合糸は、交絡度が６０〜１００個／ｍの範囲で絡合されていることが必要である。交絡度が６０個／ｍ未満では、染色加工等での受熱後に発現する捲縮糸Ａと非捲縮糸Ｂとの糸長差により、非捲縮糸Ｂが織編物表面に浮き出すぎる形となり、抗スナッギング性が悪くなる。また、１００個／ｍを超えると、絡合性が強固になりすぎてフィラメント間の空隙が減少し、目的とするふくらみ感と表面タッチが得られない。
【００１０】
すなわち、第１と第３の要件を同時に満足することで、捲縮糸Ａの持つクリンプの凹凸と非捲縮糸Ｂの浮き出る割合がバランスよく織編物表面に現れるので、所望する風合い、表面タッチと、良好な抗スナッギング性が得られるのである。しかし、このとき非捲縮糸Ｂの割合が３０質量％を超えると、織編物表面での捲縮糸Ａの割合が少なくなり、繊細な表面感が得られなくなる。そのため、本発明の複合糸を構成する非捲縮糸Ｂの割合は、３０質量％以下でなくてはならない。
【００１１】
また、本発明における複合糸を構成する非捲縮糸Ｂの強度は、耐摩耗性を考慮すると３．０ｃＮ／ｄｔｅｘ以上であることが好ましい。非捲縮糸Ｂの強度が３．０ｃＮ／ｄｔｅｘ未満になるとピリングが発生しやすくなり、さらに強度が低下すると、発生したピリングは脱落しやすいので抗ピリング性としての欠点にはならないが、ピリングが脱落した部分は、捲縮糸Ａのみが表面に出るため、繊細な表面感が損なわれやすい。
【００１２】
以上、詳細に説明したように、本発明におけるポリエステル複合糸を製編織し、染色等の熱処理を施すと、少なくとも１本のポリエステルマルチフィラメント捲縮糸Ａと少なくとも１本のポリエステルマルチフィラメント非捲縮糸Ｂからなり、非捲縮糸Ｂの割合が３０％以下の複合糸で構成した織編物であり、非捲縮糸Ｂは捲縮糸Ａに比べて糸長が１〜５％大きく、かつ、非捲縮糸Ｂが織編物の表面に浮き出た構造の織編物となる。
この織編物は、捲縮糸の持つふくらみ感、ストレッチ性、軽量性と、非捲縮糸の持つ表面タッチに加えて、双方の相乗効果による繊細な表面感を兼ね備えたものである。
【００１３】
次に、本発明におけるポリエステル複合糸の製造方法の一例を図１により説明する。図１において、供給糸Ｙ１は、第１給糸ローラ１と第１引き取りローラ４との間で、第１ヒータ２と仮撚ディスク３とで延伸仮撚加工が施されて、捲縮糸Ａとなる。
一方、供給糸Ｙ２は、第２給糸ローラ５と第２引き取りローラ７との間で第２ヒータ６により弛緩熱処理が施されて熱収縮率の低い非捲縮糸Ｂとなる。
【００１４】
次いで、捲縮糸Ａと非捲縮糸Ｂは空気交絡装置８で交絡を施されて目的とするポリエステル複合糸となり、第３引き取りローラ９を介し捲き取り機１０により引き取られる。このとき、捲縮糸Ａと非捲縮糸Ｂの空気交絡装置への給糸量は、所望の糸長差が得られるように調整する。
【００１５】

BACKGROUND OF THE INVENTION
The present invention relates to a woven or knitted fabric. More specifically, in addition to the swelling feeling, stretchability, and lightness of crimped yarns, and the surface touch of non-crimped yarns, the delicate surface feeling due to the synergistic effect of both. it relates to a woven or knitted fabric that combines.
[0002]
[Prior art]
Various methods for imparting a swell to a woven or knitted fabric have been proposed. For example, there is a method of using a different shrinkage mixed yarn using a difference in shrinkage of yarns constituting the mixed yarn. The woven or knitted fabric using the different shrinkage mixed yarn causes a difference in yarn length due to heat reception during the dyeing process, and the yarn having a low shrinkage rate is raised on the surface of the woven or knitted fabric, thereby giving a feeling of swelling. However, in this method, in order to obtain a sufficient yarn length difference, it is necessary to increase the shrinkage rate of the yarn having a large shrinkage, and thus there is a disadvantage that the texture becomes hard.
[0003]
As a method for solving this drawback, Japanese Patent Application Laid-Open No. 7-316939 proposes a mixed yarn using a yarn that shrinks by heat treatment as a core yarn and a yarn that spontaneously stretches as a sheath yarn. I play. However, the yarn exhibiting spontaneous elongation has the disadvantages that it is poor in anti-pilling and anti-snugging properties due to its high elongation and low strength, and the fabric has poor stretchability.
[0004]
On the other hand, as a method for imparting a swell and stretch to a woven or knitted fabric, there is a method of using false twisted yarn, but with this method, the surface touch of the resulting woven or knitted fabric is hard and has a characteristic characteristic of synthetic fibers. Has the disadvantage of texture. In order to eliminate this drawback, Japanese Patent Application Laid-Open No. 59-163433 proposes a pre-twisted false-twisted yarn, but it is difficult to handle a pre-twisted yarn and the cost is high. Has drawbacks.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of such a situation. In addition to the feeling of bulging, the stretchability, and the lightness of the crimped yarn, and the surface touch of the non-crimped yarn, the synergistic effect of both. It is a technical problem to provide a woven or knitted fabric having a delicate surface feeling.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has the following configuration.
(B) consists of at least one polyester multifilament crimped yarn A at least one polyester multifilament non crimped yarn B, the following equation (1), and satisfying the expression (2), and, confounding degree 60 100 pieces / m, the proportion of non-crimped yarn B weave knitting the port Riesuteru composite yarn is not more than 30 wt%, a woven or knitted fabric obtained by staining, non crimped yarn B in crimped yarn a A woven or knitted fabric having a structure in which the yarn length is 1 to 5% larger than that and the non-crimped yarn B is raised on the surface of the knitted fabric.
However,
a: Ratio of the yarn length of the non-crimped yarn B to the yarn length of the crimped yarn A x: Hot water shrinkage rate (%) of the crimped yarn A
y: Hot water shrinkage rate of non-crimped yarn B (%)
(B) The knitted or knitted fabric according to (a) above, wherein the strength of the non-crimped yarn B is 3.0 cN / dtex or more.
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The polyester composite yarn according to the present invention is required to satisfy the above-described formula (1) indicating the relationship between the crimped yarn A and the non-crimped yarn B after heat treatment as a first requirement. That is, the value of [(100−y) a− (100−x)] / (100−x) needs to be 0.01 to 0.05. The ratio of the crimped yarn B appearing on the surface is low, resulting in a hard surface touch unique to the crimped yarn, and in addition, a visually monotonous surface feeling. On the other hand, when the above numerical value exceeds 0.05, the non-crimped yarn B is excessively raised on the surface of the woven or knitted fabric, so that the anti-snugging property is remarkably deteriorated.
[0008]
The second requirement is that the ratio a of the yarn length of the non-crimped yarn B to the yarn length of the crimped yarn A is in the range of 0.90 to 1.02, as in the above formula (2). . When a is less than 0.90, as will be described later, when the ratio of the non-crimped yarn B is 30% by mass or less, the non-crimped yarn B is easily stretched by the tension applied in the subsequent processing steps such as warping. Thread breakage is likely to occur. On the other hand, when a exceeds 1.02, the form of the composite yarn under low tension becomes a lantern shape in which the non-crimp yarn B is raised between the entanglements due to the actual crimp of the crimp yarn A, and weaving Sometimes it becomes difficult to handle in subsequent processing steps, such as causing warp and fluff.
[0009]
As a third requirement, the composite yarn of the present invention needs to be intertwined within a range of 60 to 100 entanglements / m. If the degree of entanglement is less than 60 pieces / m, the non-crimped yarn B will be over-exposed on the surface of the woven or knitted fabric due to the yarn length difference between the crimped yarn A and the non-crimped yarn B that appears after receiving heat in dyeing or the like. , Anti-snugging property becomes worse. On the other hand, if it exceeds 100 pieces / m, the entanglement becomes too strong and the gaps between the filaments are reduced, and the desired swell and surface touch cannot be obtained.
[0010]
That is, by satisfying the first and third requirements at the same time, the unevenness of the crimp of the crimped yarn A and the proportion of the non-crimped yarn B that emerges appear in a balanced manner on the surface of the woven or knitted fabric. Good anti-snugging property can be obtained. However, if the proportion of the non-crimped yarn B exceeds 30% by mass at this time, the proportion of the crimped yarn A on the surface of the woven or knitted fabric decreases, and a delicate surface feeling cannot be obtained. Therefore, the ratio of the non-crimped yarn B constituting the composite yarn of the present invention must be 30% by mass or less.
[0011]
In addition, the strength of the non-crimped yarn B constituting the composite yarn in the present invention is preferably 3.0 cN / dtex or more in consideration of wear resistance. When the strength of the non-crimped yarn B is less than 3.0 cN / dtex, pilling is likely to occur, and when the strength is further reduced, the generated pilling is likely to fall off, so it does not become a drawback as anti-pilling property. Since only the crimped yarn A appears on the surface of the part that has fallen off, the delicate surface feeling tends to be impaired.
[0012]
As described above in detail, at least one polyester multifilament crimped yarn A and at least one polyester multifilament non-crimped when the polyester composite yarn in the present invention is knitted and woven and subjected to heat treatment such as dyeing. A knitted and knitted fabric composed of a composite yarn having a non-crimped yarn B ratio of 30% or less, the non-crimped yarn B being 1-5% larger in length than the crimped yarn A, and Thus, a woven or knitted fabric having a structure in which the non-crimped yarn B is raised on the surface of the woven or knitted fabric is obtained.
This knitted or knitted fabric combines the swelling feeling, stretchability, and lightness of crimped yarns, and the surface touch of non-crimped yarns, and the delicate surface feel of both.
[0013]
Next, an example of a method for producing a polyester composite yarn of the present invention with reference to FIG 1. In FIG. 1, the supply yarn Y <b> 1 is stretched false twisted by the first heater 2 and the false twist disk 3 between the first yarn supply roller 1 and the first take-up roller 4, and the crimped yarn A It becomes.
On the other hand, the supply yarn Y2 is subjected to a relaxation heat treatment by the second heater 6 between the second yarn supply roller 5 and the second take-up roller 7 to become a non-crimp yarn B having a low heat shrinkage rate.
[0014]
Next, the crimped yarn A and the non-crimped yarn B are entangled by the air entanglement device 8 to become a target polyester composite yarn, which is taken up by the winder 10 via the third take-up roller 9. At this time, the yarn supply amount of the crimped yarn A and the non-crimped yarn B to the air entanglement device is adjusted so as to obtain a desired yarn length difference.
[0015]
【Example】
EXAMPLES Next, although this invention is demonstrated concretely based on an Example, this invention is not limited to these Examples. In addition, the measurement and evaluation of each characteristic in an Example were performed with the following method.
(1) The ratio of the length of the non-crimped yarn B to the length of the crimped yarn A and the composition ratio of the non-crimped yarn B Take out a composite yarn of an appropriate length and make sure that the yarn itself does not stretch. Break down into single yarns. Classify into a single yarn group with crimps and a single yarn group without crimps, and measure the mass of each single yarn group. Next, the length is measured by stretching the single yarn to such an extent that there is no crimp or habit, and the length is calculated by the following equation.
a = I ′ / I
Composition ratio of non-crimped yarn B (mass%) = {M ′ / (M + M ′)} × 100
Where a is the ratio of the length of the non-crimped yarn B to the length of the crimped yarn A, I is the average length (mm) of the single yarn group with crimp, and I ′ is the average length of the single yarn group without crimp. (Mm), M represents the mass (g) of the single yarn group with crimp, and M ′ represents the mass (g) of the single yarn group without crimp.
(2) Hot-water shrinkage rate Measured according to JIS L-1013 8.18.1 A method, and the hot-water shrinkage rate was calculated by the following formula.
Hot water shrinkage (%) = (L1-L2) / L1 × 100
However, L1 represents the sample length (mm) before the hot water treatment, and L2 represents the sample length (mm) after the hot water treatment and air drying.
(3) Entanglement degree Measured according to JIS L-1013 8.15, and the entanglement degree was calculated by the following formula.
Entanglement degree (pieces / m) = 1000 / L
However, L represents the distance (mm) that the hook descended.
(4) Strength Measured according to JIS L-1013 8.5.1, and the strength was calculated by the following formula.
Strength (cN / dtex) = SD / F
However, SD represents the stress (cN) at the time of cutting, and F represents the positive fineness (dtex) of the sample.
(5) Anti-pilling property and anti-snugging property Anti-pilling property is tested and judged according to JIS L-1058 7.4 and 8, and anti-snugging property is tested and judged according to JIS L-1076 6.1 and 7. It was.
[0016]
Examples 1 and 2
Cationic dye-dyeable polyester highly oriented undrawn yarn 250 dtex / 48f having a birefringence of 40 × 10 −3 is used as a crimped yarn-side supply yarn. In Example 1, a polyethylene terephthalate spin draw yarn 50 dtex / min at a spinning speed of 3000 m / min. In Example 2, a polyethylene terephthalate spin draw yarn 60 dtex / 144f with a spinning speed of 3000 m / min was used as the non-crimp yarn-side supply yarn, and processing was performed under the conditions shown in Table 1 using the apparatus shown in FIG. It was.
Table 2 shows the properties of the obtained processed yarn.
[0017]
Comparative Example 1
The same crimped yarn side supply yarn as in Examples 1 and 2 was used, and a polyethylene terephthalate spin draw yarn 110 dtex / 48f with a spinning speed of 3000 m / min was used as the non-crimped yarn side supply yarn, as shown in Table 1. Processing was performed under conditions.
Table 2 shows the properties of the obtained processed yarn.
[0018]
Comparative Example 2
Using the same supply yarn as in Example 1, processing was performed under the conditions shown in Table 1. Table 2 shows the properties of the obtained processed yarn.
Table 2 shows the properties of the obtained processed yarn.
[0019]
[Table 1]
[0020]
[Table 2]
[0021]
Next, using the polyester composite yarns obtained in Examples 1 and 2 and Comparative Examples 1 and 2, respectively, a yarn subjected to a 150 T / M additional twist in the S direction, a warp density of 103 yarns / 2.54 cm, A warp double woven fabric with a weft density of 68 / 2.54 cm was woven, and then dyed by a conventional method to obtain a woven product.
The properties of the resulting textile product are shown in Table 3.
[0022]
[Table 3]
[0023]
As is apparent from Table 3, the woven fabrics obtained from the polyester composite yarns of Examples 1 and 2 had excellent anti-pilling properties and anti-snugging properties in addition to excellent surface feeling.
On the other hand, the woven fabric obtained from the polyester composite yarn of Comparative Example 1 is at a level where there is no problem in anti-pilling and anti-snugging properties, but because of the large proportion of non-crimped yarn, the surface feel is poor. there were. Further, since the woven fabric obtained from the polyester composite yarn of Comparative Example 2 has a large ratio of the length of the non-crimped yarn to the crimped yarn, the non-crimped yarn floats on the surface of the fabric, and the anti-snugging property is extremely poor. It was a thing.
[0024]
