Abstract
Description
本発明は、アクリル繊維とポリエステル繊維との複合糸及びその複合糸を含んで構成された織編物に関する。 The present invention relates to a composite yarn of acrylic fiber and polyester fiber and a woven or knitted fabric including the composite yarn.
アクリル繊維は、カチオン染料により常圧染色が可能で、発色性、保温性等に優れるものの、耐摩耗性が低く、湿熱で変形し易い等の欠点がある。一方、ポリエステル繊維は、強度、寸法安定性、イージィーケア性に優れるが、十分な濃度の染色物を得るためには分散染料による染色には１２０〜１３５℃の染色温度を得る高圧染色を必要とする。 Acrylic fibers can be dyed at atmospheric pressure with a cationic dye and have excellent color development, heat retention, etc., but have disadvantages such as low wear resistance and easy deformation with wet heat. On the other hand, polyester fibers are excellent in strength, dimensional stability, and easy care properties, but in order to obtain a dyed product having a sufficient concentration, dyeing with a disperse dye requires high-pressure dyeing to obtain a dyeing temperature of 120 to 135 ° C. .
アクリル繊維とポリエステル繊維とを組み合わせ、双方の特徴を活かし、欠点を補完するようなアクリル繊維とポリエステル繊維との混用品については、従来からも検討され、高圧染色でアクリル繊維が受けるダメージを抑えるために、混用するポリエステル繊維を分散染料により常圧染色が可能な繊維に改質する、例えば、ポリエチレンテレフタレートにポリエチレングリコールを共重合した特定扁平断面のポリエステル繊維を混用することが提案されている（特許文献１）。 A combination of acrylic fiber and polyester fiber that combines the characteristics of both, and complements the defects, has been studied in the past to suppress damage to acrylic fiber due to high-pressure dyeing. In addition, it has been proposed that polyester fibers to be mixed are modified to fibers that can be dyed at atmospheric pressure with disperse dyes, for example, polyester fibers having a specific flat cross section obtained by copolymerizing polyethylene terephthalate with polyethylene glycol (patents). Reference 1).
また、分散染料により高圧染色されるポリエステル繊維の染色性を改善し、常圧染色で分散染料及びカチオン染料によって染色可能とするために、ポリエチレンテレフタレートに５−ナトリウムスルホイソフタル酸を０．４〜５モル％、及びアジピン酸を２〜１５モル％を共重合させた改質ポリエステル繊維も知られている（特許文献２、特許文献３、特許文献４）。 In addition, in order to improve the dyeability of polyester fibers that are dyed at high pressure with disperse dyes and to enable dyeing with disperse dyes and cationic dyes at normal pressure dyeing, 0.4 to 5 of 5-sodium sulfoisophthalic acid is added to polyethylene terephthalate. Modified polyester fibers obtained by copolymerizing 2% to 15% by mole of adipic acid and adipic acid are also known (Patent Document 2, Patent Document 3, and Patent Document 4).
しかしながら、アクリル繊維とポリエステル繊維との混用品は、混用するポリエステル繊維のみを、特に染色性を改質しただけでは混用品の用途が限定され、各繊維の機能性能が充分に発揮される多様な製品に対応しての素材としては満足できるものではない。 However, mixed products of acrylic fiber and polyester fiber are limited to the polyester fiber to be mixed, especially by modifying the dyeability, and the use of the mixed product is limited. It is not satisfactory as a material corresponding to the product.

In accordance with JIS L1095, an apparent Young's modulus (N / mm 2 ) was measured using a tensile tester (Orientec Corp., Tensilon UTM-II type) at a gripping interval of 20 mm and a tensile speed of 20 mm / min.
（通気度）
ＪＩＳ Ｌ１０９６に準拠し、フラジール形通気性試験機にて試料片を通過する空気量（ｃｍ３／ｃｍ２・ｓｅｃ）を測定した。
(Air permeability)
In accordance with JIS L1096, the amount of air passing through the sample piece (cm 3 / cm 2 · sec) was measured with a Frazier type air permeability tester.
（耐摩耗性）
ＪＩＳ Ｌ１０９６Ｅ法に準拠し、研磨紙Ｐ１２００Ｃ−ＣＷ（サンドペーパー）を用い、試料片が摩耗し孔があいた時点までの摩耗回数（回）を測定した。
(Abrasion resistance)
In accordance with the JIS L1096E method, the number of wear (times) until the sample piece was worn and had a hole was measured using abrasive paper P1200C-CW (sand paper).
（吸水性）
洗濯１回後乾燥し、温度２０℃、湿度６５％ＲＨで調温湿した試験片を準備し、ＪＩＳ Ｌ１９０７滴下法に準拠し、試料片に滴下した水滴が消失するまでの時間（秒）を求めた。時間が少ないほど吸水性が大きい。
(Water absorption)
Prepare a test piece that was dried after washing once and dried at a temperature of 20 ° C. and a humidity of 65% RH. In accordance with JIS L1907 dropping method, the time (seconds) until the water droplets dropped on the sample piece disappeared. Asked. The less time, the greater the water absorption.
（速乾性）
拡散性残留水分率試験で評価した。洗濯１回後乾燥し、温度２０℃、湿度６５％ＲＨで調温湿した１０ｃｍ×１０ｃｍの試験片の質量（Ｗ）を測定し、試験片に水を０．６ｍＬ滴下し質量（Ｗ０）を測定する。この試験片を温度２０℃、湿度６５％ＲＨの雰囲気で吊り干して５５分後の質量（Ｗ１）を測定し、下式で残留水分率を算出し、この残留水分率を速乾性とした。数値が小さいほど速乾性が大きい。
速乾性（％）＝［（Ｗ１−Ｗ）／（Ｗ０−Ｗ）］×１００
(Quick-drying)
Evaluation was made by a diffusive residual moisture content test. The mass (W) of a 10 cm × 10 cm test piece dried after washing and dried at a temperature of 20 ° C. and a humidity of 65% RH was measured, and 0.6 mL of water was dropped onto the test piece and the mass (W 0 ). Measure. The test piece was suspended and dried in an atmosphere of a temperature of 20 ° C. and a humidity of 65% RH, and the mass (W 1 ) after 55 minutes was measured. The residual moisture content was calculated by the following equation, and the residual moisture content was determined to be quick-drying. . The smaller the value, the faster the quick drying.
Quick-drying (%) = [(W 1 −W) / (W 0 −W)] × 100
（非密着性能）
下記の方法により、生地が濡れた時の肌面との密着の状態を数値化したもので、下記の試験による水分量（ｍＬ）で非密着性能を表した。水分量が多くなっていくと、張り付く力（ｇｆ）が発生する。生地の水分量が増えても、張り付く力が発生しなければ、べとつき感が無く肌離れ性が良いと判断する。
使用機器：ハンディー圧縮試験機(カトーテック社製、ＫＥＳ−Ｇ５)
試料サイズ：５ｃｍ×５ｃｍ
試料準備：幅６．５ｃｍ、長さ１１ｃｍ、厚さ１ｍｍのステンレス板に試料と同サイズの両面テープを貼り、その上に試料の肌面が上になるように生地を貼り付けたものを試料とする。
機器設定：試験機に１ｋｇのロードセルと１０ｃｍ２の表面にゴム板を取り付けた圧縮子を取り付け、圧縮速度を０．２ｍｍ／ｓｅｃ、最大加圧荷重を５０ｇｆにセットする。
操作：試料中央部に０．１ｍＬの水を与え、試験機にセットし、試料に圧縮子を押し当て、引き上げる圧縮・除圧試験を行う。その後、更に０．１ｍＬの水を与え同様の操作を行い、以後０．１ｍＬの水を与える毎に同様の操作を行う。
測定・判定：圧縮過程から除圧過程に反転する際、通常では描かれたチャート上圧縮前の０に戻るだけであるが、水分が与えられ、張り付く力が発生すると、除圧時にチャート上でマイナスの力が発生する。これは試料が圧縮子に張り付き、一緒に上についていこうとするため発生する力である。試料の水分量を段階的に増やしていき、この張り付き力が発生した時点、すなわち、除圧地にチャート上でマイナスの力が発生した時点で試験終了とし、その時点での試料に与えた水分量を非密着性とする。
(Non-adhesion performance)
By the following method, the state of close contact with the skin surface when the fabric was wet was quantified, and the non-contact performance was expressed by the amount of water (mL) by the following test. As the amount of water increases, a sticking force (gf) is generated. Even if the moisture content of the dough increases, if the sticking force does not occur, it is judged that there is no stickiness and the skin peelability is good.
Equipment used: Handy compression tester (Kato-Tech, KES-G5)
Sample size: 5cm x 5cm
Sample preparation: A sample with a double-sided tape of the same size as the sample applied to a stainless steel plate with a width of 6.5 cm, a length of 11 cm, and a thickness of 1 mm, and a fabric attached to the sample so that the skin surface is on top And
Equipment setting: A 1 kg load cell and a compressor with a rubber plate attached to the surface of 10 cm 2 are attached to the test machine, the compression speed is set to 0.2 mm / sec, and the maximum pressure load is set to 50 gf.
Operation: Apply 0.1 mL of water to the center of the sample, set in a testing machine, press the compressor against the sample, and perform a compression / decompression test to pull it up. Thereafter, 0.1 mL of water is further supplied to perform the same operation, and thereafter, every time 0.1 mL of water is supplied, the same operation is performed.
Measurement / judgment: When reversing from the compression process to the depressurization process, it usually only returns to 0 before compression on the drawn chart, but when moisture is applied and a sticking force is generated, Negative force is generated. This is the force that occurs as the sample sticks to the compressor and tries to keep it together. The moisture content of the sample is increased in stages, and when this sticking force is generated, that is, when a negative force is generated on the chart in the decompressed area, the test ends, and the moisture applied to the sample at that time The amount is non-adhesive.
（ｑ−ｍａｘ値）
ｑ−ｍａｘ値は、精密迅速熱物性測定装置（カトーテック社製サーモラボII型）を使用して測定された接触冷温感を評価する値で、数値の小さい程温感を、数値の大きい程冷感を示すもので、このｑ−ｍａｘ値を温感性の評価に用いた。測定では、２０℃の温度に設定した試料台の上に試料片（生地）を置き、試料片の上に４０℃の温度に温められた貯熱板を接触圧０．０９Ｎ／ｃｍ２で重ねた直後、蓄えられた熱量が低温側の試料に移動する熱量のピーク値（Ｊ／ｓｅｃ／ｃｍ２）を測定した。
(Q-max value)
The q-max value is a value that evaluates the cold feeling of contact measured using a precise rapid thermophysical property measuring apparatus (Thermo Lab II type manufactured by Kato Tech Co., Ltd.). This q-max value was used for evaluation of warmth. In the measurement, a sample piece (dough) is placed on a sample stage set to a temperature of 20 ° C., and a heat storage plate heated to a temperature of 40 ° C. is stacked on the sample piece at a contact pressure of 0.09 N / cm 2 . Immediately after that, the peak value (J / sec / cm 2 ) of the amount of heat at which the stored amount of heat moved to the low temperature side sample was measured.
