1277668 玖、發明說明： 【發明所屬之技術領域】 本發明係有關一種具有吸濕發熱性之彈性纖維與其織 物等用途、及針織物之製法。 【先前技術】 以往重視保濕性之布帛，一般而言有厚或重的傾向。穿 著此等布帛時，會有重、不易活動、有損時髦性的問題。 而且，由於發汗後放濕性不充分，故在通勤電車等中發汗 時會有悶熱感等之不快感，以及汗溫下降後會產生冷感等 問題，於市場中企求薄且保溫性優異的布帛。 # 特別是使用彈性纖維之伸縮性布帛中，布帛與肌膚密 接，爲確保保溫性以作爲厚質布帛時，上述問題點特別顯 著。另外，於活化貼身性、追求美觀性之用途例如絲襪、 緊身衣褲，由於過厚會降低穿著時之美觀性，產生很多問 題。 爲以此等薄質布帛確保保溫性時，進行各種檢討，多半 選擇變更編織組織或汎用紗者，其效果無法確定極爲充 分，目前仍無法製得同時確保保溫性、輕量性、舒適性、 肇 美觀性之布帛。 此外，聚酯纖維或耐龍纖維、以及聚胺甲酸酯彈性纖維 之合成纖維，與棉或羊毛、絲之天然纖維不同，由於親水 性官能基含量少，故一般缺乏吸濕性。因此，長年硏究合 成纖維之親水化技術，例如提案有染色工業、Vol· 47，1277668 发明Invention Description: The present invention relates to a method for producing an elastic fiber having moisture absorption and heat resistance, a fabric thereof, and a knitted fabric. [Prior Art] In the past, the importance of moisturizing fabrics tends to be thick or heavy. When wearing these fabrics, there are problems that are heavy, difficult to move, and detrimental to fashion. In addition, since the moisture release property is insufficient after sweating, there is a feeling of unpleasant sensation such as sultry sensation when sweating in a commuter train or the like, and a problem such as a cold sensation after a decrease in sweat temperature, and it is thin in the market and excellent in heat preservation property. Cloth. # In particular, in the stretchable fabric using elastic fibers, the fabric is in close contact with the skin, and the above problem is particularly remarkable in order to ensure heat retention as a thick fabric. In addition, in applications such as stockings and tights that activate the fit and the pursuit of aesthetics, excessive thickness reduces the appearance of wearing, and causes many problems. In order to ensure the heat retention of such thin fabrics, various reviews have been made, and most of them have been selected to change the weave structure or the general-purpose yarn. The effect cannot be determined to be extremely sufficient, and it is still impossible to obtain heat insulation, light weight, comfort, and肇 Beautiful fabric. Further, the synthetic fiber of the polyester fiber or the nylon fiber and the polyurethane elastic fiber is generally inferior in hygroscopicity to the natural fiber of cotton or wool or silk because of the small content of the hydrophilic functional group. Therefore, the hydrophilization technology of synthetic fibers has been studied for many years, such as the dyeing industry, Vol. 47,

聚醯胺系聚合物、高吸水性聚胺甲酸酯系聚合物 於此等高吸水性聚合物局部存在，會有降低物性 紗安定性之問題。另外，由於一般該高吸水性聚 交聯，與因吸水產生膨脹、導入上述親水性聚醇 聚胺甲酸系彈性纖維會導致膨脹、被覆或編成工 殘渣附著於接紗導線等，而有斷紗或品質不佳的 題。 此外’近年來對聚胺甲酸酯系彈性纖維之耐熱 高’特別是自古以來企求可與必須高溫高壓染料 維交織的聚胺甲酸酯異彈性纖維。對該要求而H

成型化藉由熱處理予以高分子化的技術係爲提高聚胺甲酸 酯系彈性纖維之耐熱性技術，係爲已知。然而，藉由此等 技術之聚胺甲酸酯系彈性纖維，雖可提高後加工中對熱處 理之耐熱性，惟視目的而定不易控制生產量、且處理性不 佳、後加工通過性有問題。 另外，在聚醇成份中導入上述親水性基時，會有後加工 中熱處理之耐熱性降低，且不易與必須高溫高壓染色之聚 酯纖維交織的問題。 其次，說明有關織物的習知技術。聚酯系纖維、聚醯胺 系纖維、纖維素纖維等之非伸縮性纖維與聚胺甲酸酯彈性 紗所成的織物，由於伸縮性能優異，可使用於褲襪或短絲 襪、胸罩、韻律操服等基本衣服或、肚兜、運動衣料、滑 雪褲、伸縮厚棉褲等外衣等之其他伸縮包帶、具伸縮之緊 身內衣褲、伸縮膠帶之基布、支援類醫療用途、或伸縮鞋 之基布等多種用途。 特別是婦人用內衣褲用途中由於適當的伸縮性與質薄， 故以聚胺甲酸酯等彈性紗與耐龍之複合編織爲主流。然 而，由於合成纖維特有的透濕性不佳，會有悶熱感的問題， 解決悶熱感之方法除上述利用吸濕性聚胺甲酸酯外，例如 曰本專利公開特開平9-228 1 55號公報及特開平9-256278號 公報中揭示利用耐龍纖維之吸濕特性經改良的吸濕性耐龍 紗。 作爲貼身衣物所要求的舒適性係以濕度控制效果與保濕 性能評估，係爲抑制穿著初期自己發熱、及加溫效果與發

提案使丙烯酸系吸濕發熱性樹脂粒子在後加工中藉由樹脂 黏合法或接枝聚合法固定於耐龍或聚酯布帛表面上的方 法，惟在表層系中存在有吸濕粒子，且吸濕時有黏腻問題 或欠缺洗濯耐久性的問題或質感硬化的情形。 其次，說明有關絲襪之習知技術。耐龍紗出現以來，普 遍以絲襪作爲提高婦人腳部線條美的衣料，且褲襪之出現 更延伸擴展其使用量。另外，藉由嗜好的高級化，企求更 透明、伸縮性更高的商品差別化。其一企求更繫緊感之強 支撐型絲襪，使用聚胺酯彈性纖維與耐龍紗之表層紗的絲 襪登場，至今仍爲主流。就可得合成單紗之強度高、質薄、 穿著耐久性優異的絲襪而言係爲至寶，惟就質薄而言會有 欠缺嚴寒時之保溫性缺點。而且，由於吸濕性低，企求改 良發汗時悶熱情形。另外，該悶熱情形在鞋內會有異味情 形，係爲女性的煩惱之一。 合成纖維中存在有很多吸濕性優異的纖維，大致上強度 低、質薄、無法使用於企求耐久性之絲襪用途，絲襪所使 用的單紗以耐龍或聚酯爲主流，特別是耐龍在合成纖維中 公定水分率高、強度亦高，故使用耐龍單紗。然而，於嚴 寒時或酷熱時皆有很多的問題。嚴寒用需爲厚質型’爲對 1277668 外觀而言另很多年輕女性不滿。反之，酷熱時亦可赤腳不 穿著絲襪的時候，很多時候爲重視外觀、繫緊感時仍不滿 地穿著。 近年來，稱爲支撐型之繫緊感強的絲襪要求更高，以胺 甲酸酯等彈性紗與耐龍之複合紗爲主流，惟爲解決悶熱感 之手段時利用上述耐龍纖維之吸濕特性經改良的吸濕性耐 龍紗，或利用上述吸濕性聚胺甲酸酯予以進行，提案改善 吸放濕性、富含舒適性之絲襪，直至目前吸濕發熱或抗菌、 消臭效果仍不足。 吸濕發熱效果以習知棉或羊毛纖維係爲已知，惟以與上 述型式相同者仍不適合於要求薄質、美觀性之婦人絲德。 有鑑於此等狀況，例如曰本專利公開、特開000 b丨3 1 號公報中’提案在後加工中使吸濕發熱樹脂粒合樹 脂固定於耐龍與聚胺甲酸酯彈性紗之複合紗構成的絲德方 法，惟吸濕粒子存在於表層之耐龍紗中，且吸濕時會有黏 腻問題或洗濯耐久性不充分的問題、且有質感硬化的情 形。 其次，主要說明有關長纖維織物之習知技術。 換言之，運動中通常係於開始運動前使筋肉或關節暖 和，以防止受傷、提高運動能力，進行暖身運動。特別是 嚴寒時之屋外競技中暖身極爲重要。 此時，運動選手穿著的暖身衣，由於習知衣料原料雖具 保溫效果、惟不具加溫效果，故需長時間暖身。爲避免該 情形、在短時間內有效地暖身時，穿著妨礙蓮動性之厚質 衣料時，會多消耗體力。衣服內雖可放置懷爐等之熱源， -10- 1277668 惟在該加溫下僅可局部加溫、使其效果受到限制且妨礙運 動。 另外，冬天在屋外長時間運動之高爾夫球或滑雪，企求 具有加溫效果之服裝。而且，除運動服外冬季用一般衣料 或內衣褲類亦企求具有加溫作用。 此處，具有吸濕性及溫度調節作用之纖維例如日本專利 公開、特開9-5 9 8纟>^^公報記載的交聯丙烯酸系纖維。 然而’交聯丙烯酸系纖維不僅不具有適於運動服裝之伸縮 性’且沒有考慮容易活動性。 此外，主要有關短纖維織物、即職場所穿著的工作服， 一般衣料企求保溫效果或裝飾效果外，企求身體之保護效 果。例如屋外作業用之工作服亦企求具防止受傷、或遮斷 紫外線、守護肌膚等功能。而且，醫療用制服或視其所需 實驗用制服，企求具有防止因細菌等之身體污染效果等。 另外，工作服中企求適當保持衣服內之溫度及濕度，且 可容易作業，特別是在屋外之冬季作業用服，企求具有保 Μ效果與將汗放出衣服外之效果。 必須具有吸濕或吸水功能時，主要使用棉布帛，惟由於 棉纖維不具速乾性，會有黏腻或工作休息時之冷感。羊毛 布帛雖保溫效果及衣服內之濕氣透出至外部效果優異，惟 作爲工作服之機械耐久性不佳。 此處，具有吸濕性及溫度調節作用之纖維物上述交聯丙 烯酸系纖維係爲已知。然而，交聯丙烯酸纖維不具適合作 爲工作服等之伸縮性，且不具容易活動性。 【發明內容】 -11- 1277668 本發明之第1課題係提供一種適合保溫性高、具有舒適 性、美觀性之伸縮性布帛的彈性纖維，而且，提供一種適 於後加工通過性良好、具有優異耐熱性、且可快速自肌膚 除去因運動時發汗所產生的水蒸氣，沒有悶熱感之伸縮衣

本發明之彈性纖維以吸濕及/或吸水時最大溫度上升爲2°C 以上較佳。更佳者爲3 °C以上。具有該特性之彈性纖維， 薄質、可賦予布帛具高保濕性。惟吸濕及/或吸水時之最大 溫度上升過高時，除製紗時斷紗情形增加外，使用於實際 編織物中會引起不需的過高溫度上升情形，故不企求，通 常彈性纖維之最大溫度以1 〇 °c以下爲宜。 另外，本發明之彈性纖維以具有上述發熱性，且20 °c X 65%RH之吸濕率爲0.5%以上，20°C X 95%RH之吸濕率爲 1.5 %以上較佳。更佳者爲20°C X 65%RH之吸濕率爲1.0〜 5.0%，20°C X95%RH之吸濕率爲2·0〜15·0%。具有上述特 徵之彈性纖維由於除使一定保溫性之布帛儘可能薄質外、 且有效地吸收汗，故即使體溫微溫時流汗、仍不會有不舒 適感，係爲暖和且不會有悶熱感之高度舒適性。另外，亦 可解除發汗後汗冷卻時之冷感。 -17- 1277668 本發明之彈性纖維係以20 °C X 65 %RΗ與20°C X 95%RH 之吸濕率差爲1·0%以上較佳、更佳者爲2.0%以上。該數値 係表示吸汗之能力，該數値愈大時能力愈高。 其次’說明有關本發明之聚胺甲酸酯系彈性纖維之耐熱 性。首先’本發明之聚胺甲酸酯系彈性纖維的乾熱固定性 係以藉由下述測定法、PSD(100%伸長下、乾熱190°C處理1 分鐘後之乾熱定形率）以60%以上較佳。若該數値小於60% 時，在預固定工程中質地之尺寸安定性不佳，故不爲企求。 然後，本發明之聚胺甲酸酯系彈性纖維之濕熱固定性藉 由下述測定法、PSW( 100%伸長下60分鐘內、濕熱、自40 °C昇溫至’13(TC後，連續在濕熱、130°C下熱處理60分鐘後 之濕熱定形率）爲75 %以下較佳。該數値係表示染色工程中 之耐熱性者，若該數値愈大時耐熱性愈優異。總之，若PSW 大於75%時，不易與必須高溫高壓染色的聚酯纖維交編， 且彈性回覆率會降低，故不爲企求。 由於一般於衣料用布帛中彈性纖維不會露出於布帛表 面、存在於內部，故該彈性纖維發熱時自布帛內部發熱， 可達成發熱體以斷熱材覆蓋的相同效果，可有效保溫、可 得蓄熱性，及可得高舒適性。賦予布帛表面露出的非彈性 纖維具發熱性時，反人體側露出的部分快速冷卻效果不 佳、且人體側之部分發熱時，降低舒適性，故不企求。 而且，於吸濕時使用黏合劑藉由分離等使發熱劑等附著 於布帛表面上，或含於露出表面之纖維的方法，除容易損 害質感外、於分離中洗濯耐久性不充分，故不爲企求。 於一般的使用方法中，彈性纖維很少會露出布帛表面， -18- 1277668 有不會損及質感之優點。彈性纖維內部以含有吸濕 之劑較佳。 首先’賦予吸濕性之方法係使高吸放濕性微粒子 合於彈性纖維之原料聚合物、予以紡紗極爲有效。 維之典型例如聚胺甲酸酯系彈性纖維。紡紗可藉由 紗、濕式紡紗、熔融紡紗之任一方法實施。高吸放 粒子可使用有機系及/或無機系者，例如聚丙烯酸系 微粒子、聚乙烯系聚合物微粒子、聚醯胺系聚合物微 聚胺甲酸酯系聚合物微粒子、多孔質二氧化矽微粒 水性二氧化矽微粒子等，惟爲防止物性降低、紡紗 及加工通過性佳而言，粒徑爲20μιη以下、較佳者| 以下、更佳者爲5μιη以下。最佳者爲2μιη以下。此 成上述目的時，於紡紗過程中必須使高吸放濕性微 散於纖維中之故。若粒徑大於20 μιη時，添加混合後 析，且纖維表面上會有暈開情形，因紡紗切斷或後 殘渣附著而形成斷紗的原因。惟若平均粒徑過小時 間容易引起凝聚情形，反而會使聚胺甲酸酯系彈性 之分散性不佳，故以0 · 1 μιη以上較佳。而且，微粒 狀沒有特別的限制，可以圓球型、稍扁平球型、不 之任何形狀。 高吸放濕性微粒子對聚胺甲酸酯系彈性纖維而言 〇·2重量％以上較佳。更佳者爲0.5重量％以上。若 重量％時，缺乏吸濕性，故不爲企求。惟含量若過大 紡紗階段之曳紗性降低、且斷紗情形多，故以50重 下較佳、更佳者爲48重量％以下。 、發熱 添加混 彈性纖 乾k紡 濕性微 聚合物 粒子、 子、親 作業性 I 1 0 μιη 係爲達 粒子分 粒子偏 加工時 ，粒子 纖維內 子的形 定形等 含量爲 、於 0 · 2 時，在 :量％以 1277668 本發明所使用的高吸放濕性微粒子之膨脹度以2 Ο Ο %以 下較佳、更佳者爲100 %以下。若膨脹度大於200%時，由 於聚胺甲酸酯系彈性纖維本身因水分產生膨脹情形，成爲 在表層被覆或編成時因殘渣附著產生斷紗、品質不良的原 因。高吸放濕性微粒子之膨脹度愈小愈佳。於本發明之聚 胺甲酸酯系彈性纖維中，因吸濕之膨脹不僅會僅使高吸放 濕性有機微粒子變小，形成纖維之聚胺甲酸酯系聚合物幾 乎不會因吸濕而引起膨脹情形，很少會有因伴隨殘渣附著 於接紗導線等之斷紗情形或品質不良的後加工上的問題。 本發明所使用的高吸放濕性微粒子，由於20°C X 65 % RH 之水分率大’以非生體系聚合物之高吸放濕性有機微粒子 較佳’更佳的化學組成如下述，20 °C X 65 %RH之高吸放濕 性有機微粒子的水分率爲30%以上較佳。更佳者爲35%以 上、最佳者爲40%以上。以往，具有吸濕性之微粒子中， 吸濕性最高者爲羊毛粉末或甲殼質粉末，20 t： X 65 %RH之 水分率爲15%以上之高値。此外，澱粉或纖維素、絲、膠 原等多糖類系微粒子或蛋白質系微粒子較上述羊毛粉末或 甲殼質粉末小8〜1 2 %。其他尿素樹脂系或蜜胺樹脂系粉末 之20°C X 65 % RH之水分率達30 %以上，故不爲企求、 而且’爲防止彈性纖維之物性降低、紡紗操作性及後加 工通過性良好時，高吸放濕性微粒子之粒徑爲20μιη以下、 較佳者爲ΙΟμιη以下、更佳者爲5μιη以下、最佳者爲2μπι 以下，其含量對纖維而言以0.2〜50重量％較佳。含量若較 該範圍低時無法得到充分的效果，若較高時製造彈性纖維 時會誘發斷紗情形等缺點。 -20- 1277668 本發明之彈性纖維中含有由非生體系聚合物所成的高吸 放濕性有機微粒子時，該高吸放濕性有機微粒子具有的親 水性基爲鹽式羧基、鹽型磺酸基、鹽型磷酸基、鹽型磷酸 基等，鹽有Li、Na、K等之鹼金屬、Mg、Ca、Ba等之鹼土 類金屬、Cu、Ag、Μη等之其他金屬、銨、胺等之有機陽離 子等鹽，除鹽型外亦可以含有酸性基。高吸放濕性有機微 粒子係在含有50重量％以上丙烯腈之丙烯腈系聚合物中藉 由胼、二乙烯苯或三烯丙基異氰酸酯處理導入交聯架構， 且使殘存的腈基藉由加水分解化學變換成鹽式羧基，以具 有l.Ommol/g鹽式羧基者更佳。雖沒有特別的限制，更具 體而言例如（a)係在含有85重量％以上丙烯腈之丙烯腈系聚 合物中藉由氮含量增加1·〇〜15.0之胼處理導入交聯架 構，且使殘存的腈基藉由加水分解化學變換成鹽式羧基， 以具有l.〇mmol/g鹽基羧基之丙烯酸系金屬變換粒子、（b) 藉由二乙烯苯或三烯丙基異氰酸酯處理導入交聯架構，且 於含有50重量％以上之丙烯腈系聚合物中使殘存的腈基藉 由加水分解化學變換成鹽式殘基’以具有2.Ommol/g鹽式 羧基之丙烯酸系金屬變換粒子等。鹽式羧基量以4.0〜 10 .Ommol更佳。高吸放濕性有機微粒子之製法例如可藉由 日本專利公開、特開平8-2256 1 0號公報記載的方法製造。 本發明彈性纖維之吸濕發熱作用由於主要爲該鹽式羧基由 來，故鹽式羧基濃度（m m ο 1 / g)與纖維中微粒子濃度（重量％) 之積通常爲40〜8〇、較佳者爲45〜75，使纖維中之微粒子 濃度固定較佳。若彈性纖維中微粒子含量爲上述範圍時， 身體可感覺充分暖和感，且不會因斷紗導致不易紡紗的問 -21- 1277668 題。 此等金屬變換粒子爲交聯丙烯酸系聚合物微粒子，該出 發微粒子之丙烯腈系聚合物中與丙烯腈倂用的單體例如鹵 化乙烯基、鹵化次乙烯基、丙烯酸酯、甲基丙烯酸酯、對 苯乙烯磺酸等含磺酸之單體及其鹽、丙烯酸等含羧酸之單 體及其鹽、丙烯醯胺、苯乙烯、醋酸乙烯酯等。 含有該高吸放濕性有機微粒子之彈性纖維兼具良好的發 熱性及吸濕性。該高吸放濕性有機微粒子添加於聚胺甲酸 酯彈性纖維時，與添加於酯或耐龍之非彈性纖維時相比， 具有顯著的發熱、吸濕性，另外聚胺甲酸酯彈性纖維之強 伸度等物性極爲降低。理由雖不明，可推測爲在纖維表面 容易暈開之故。另外，該高吸放濕性有機微粒子具有優異 的抗菌性、消臭性，特別是具有絲襪或緊身衣褲等所使用 的彈性纖維之加成價値者。 本發明之彈性纖維係指在社會觀點上具有橡膠彈性舉動 之纖維，例如至少可50%以上伸張，更佳者可1〇〇%以上伸 張’且具有20%以上之回復率等。此處之回復率係指對拉 伸全體而言藉由回復縮小的長度。典型例如具有特別優異 伸縮性之聚胺甲酸酯系彈性纖維。 本發明之彈性纖維所使用的聚胺甲酸酯聚合物可以爲使 由聚醇與過多莫耳之二異氰酸酯化合物所成的兩末端爲異 氰酸酯基之中間聚合物溶解於N，N，-二甲基乙烯醯胺、二甲 基亞楓等惰性有機溶劑中，且使二胺化合物反應所得者。 上述聚醇沒有特別的限制，例如聚合物二醇。具體例如 選自於聚氧化乙二醇、聚氧化丙二醇、聚氧化四甲二醇、 -22- 1277668 聚氧化五甲二醇及聚氧丙烷四甲二醇等之聚醚二醇，由一

本發明彈性纖維之交織原料可以爲熱塑性合成纖維、天 -23- 1277668 然合成纖維、再生纖維中任何一種，爲熱塑性合成纖維時 可ί采用聚酯纖維、聚醯胺纖維，爲天然纖維時可採用棉、 羊毛’再生纖維時可採用高濕模量黏膠纖維。 就對象原料與本發明之彈性纖維交織而言不受此等所限 制’例如交織時一般使彈性纖維以對象原料被覆時，使聚 酯纖維等被覆於彈性纖維上使用於經紗及/或緯紗。而且， 與對象原料交織時可直接與對象原料拉取、編織，同時以 被覆紗織入。 有關所得伸縮性編織物之染色加工可採用使生機鬆弛· 精練後預固定，進行染色、乾燥、質感處理，加工固定之 一般加工工程。 其次，說明有關本發明之針織物。 本發明之針織物係爲由上述彈性紗與非彈性纖維構成的 高伸縮性針織物，惟本發明之非彈性纖維爲以羊毛、棉、 絲綢等天然纖維或耐龍、聚酯等合成單紗，斷裂伸度小於 100%之纖維。非彈性紗實質上爲不含吸濕發熱性有機微粒 子，針織物表裏表面以非彈性纖維被覆較佳。此處所指實 質上不含吸濕性有機微粒子係爲不含在針織物之吸濕率左 右以上之粒子量，即使含有些許、亦沒有關係。 本發明針織物之彈性紗的混用率，就吸濕加溫效果而言 構成針織物之20重量％以上較佳’就保持穿著時內襯佳而 言以50重量％以下較佳。本發明之彈性紗與棉纖維或毛纖 維相比，由於吸放濕速度慢、到達吸濕水準高，結果發熱、 放熱在溫和狀態下長時間繼續進行’特別是發汗停止後纖 維溫度之降低速度慢、具有抑制運動停止後之冷感。而且， -24- 1277668 鹽式羧基除吸濕發熱效果外，具有消臭、制菌抗菌、pH緩 衝、制電等各種效果，且爲具備作爲暖身衣之理想性能的 製品。此外，由於在陰乾下仍不會有細菌繁殖，故可適合 作爲游泳衣。 本發明之針織物係吸濕時針織物之表面溫度上升3 °C以 上。該吸濕時之發熱係使針織物在7 0 °C下乾燥2小時後， 在加入有矽膠之乾燥器中調溫8小時以上後，在調整爲3 2 °C、70 %RH之氣氛中以熱度表使針織物表面連續5分鐘以 測定表面溫度，測定最大的溫度，與3 2 °C之差値作爲上升 溫度。該溫度小於3 °C時缺乏體感效果，上升溫度愈高愈 佳，大約爲10 °C。 針織物之伸長特性係爲重要的要件，爲成爲提高保溫 性、儘可能與身體密接、且不會阻害運動性之衣料時，針 織物必須爲5 0 %以上之定荷重伸長率，較佳者定荷重伸長 率爲60〜1 00%之伸長性。另外，爲保持與身體之密接性、 回復性優異、不損美觀時，定荷重伸長回復率以5 0 %以上 之伸長回復性爲宜。較佳者爲6 0〜9 5 %。 彈性紗與非彈性纖維之混用係形成複合紗後，採用針織 物的方法或彈性紗與非彈性紗交織的方法。惟交織時，針 織物表裡之表面以不直接爲彈性紗較佳。此係由於因吸濕 導致吸濕纖維表面黏腻，故實質上不吸濕多量水分，肌膚 不會感覺非彈性纖維之黏腻感。 形成複合紗的方法係爲複合紡績紗或被覆紗之方法。形 成複合紡績紗之方法的具體例如非彈性纖維之精紡工程中 粗紗牽引範圍中使彈性紗以適當牽引倍率供應，形成芯核 -25· 1277668 複合紗的方法。形成被覆紗之方法的具體例如使彈性紗以 適當的牽引倍率供應，於其上捲取非彈性紗的方法等。爲 前者時，可使用羊毛、棉、麻及聚酯短纖維、耐龍短纖維 作爲非彈性纖維。爲後者時，可使用絲綢、聚酯單紗、耐 龍單紗、棉及羊毛之紡績紗。爲聚酯單紗、耐龍單紗時亦 可使用作爲複合假撚加工紗。 此等之複合紗可以單獨使用、或與其他纖維紗交織利用 作爲圓針織物，於針織物具有較大伸度之優點。組織係伸 度滿足必要條件即可，沒有特別的限制。 爲經針織物時’特別是形成針目之非彈性單紗供應的抒 後，即使使用彈性紗於任何抒中，由於彈性紗可爲以非彈 性單紗包圍形成針織物，故彈性紗可使用裸紗。此時，非 彈性紗可使用紡績紗，惟爲抑制絨毛或風棉之操作性降低 時，以單紗較佳。 本發明之針織物適合使用於內衣褲。適合內衣褲使用的 針織物，其特徵爲具有吸濕能，吸濕時具有發熱、加溫效 果。此點於下述之絲襪發明中亦相同。首先說明有關本發 明針織物於穿著時之溫濕度變化。本發明之溫濕度係指緊 身衣之針織物的針目中包含的空氣之溫濕度，該變化影響 舒適性。穿著時因運動等之刺激使體溫上升時，爲使體溫 冷卻、自皮膚表面放出汗，針目含有氣相之溫度、濕度同 時上升，遂有不舒適感。此時，針織物具有吸濕性時，可 抑制氣相濕度降低，且可抑制不舒適感降低。吸濕之水分 自纖維表面放濕至外部環境。吸濕時發熱加溫時，氣相中 水分量由於以同等僅溫度上升、相對地濕度降低，且促進 -26- 1277668 自皮膚發汗，結果抑制體溫降低。該現象直至緊身衣褲到 達吸濕平衡狀態之連續數分鐘。最後，吸濕量與放濕量到 達平衡，且停止加溫效果。此時緊身衣褲之溫度下降，到 達平衡溫度。運動被停止、發汗停止時，僅進行放濕、最 後回復至初期狀態。 本發明針織物所使用的彈性紗與棉纖維或羊毛纖維相比 時’吸放濕速度變慢、吸濕到達水準高，結果發熱、放熱 在溫和狀態下長時間繼續進行，特別是有效地抑制發汗停 止後纖維溫度之降低速度變慢，抑制運動停止後之冷感。 本發明人等再三深入硏究檢討藉由改變彈性紗中之吸濕 性微粒子濃度，以穿著試驗可感覺吸濕時之加溫效果，結 果可確認昇溫速度必須爲5 °C /分以上之昇溫能力。較佳者 爲7 °C /分以上。以受到外部影響之外溫愈低，昇溫能力愈 局爲宜。 本發明使用於緊身內衣褲之針織物可使用上述聚胺甲酸 酯系彈性纖維的典型彈性紗與聚酯系纖維、聚醯胺系纖 維、及纖維素系纖維等之非彈性纖維所成的伸縮性針織物 者，使用細圓紗，爲形成薄質、富含美觀性之針織物時， 以使用聚酯系纖維、聚醯胺系纖維之單紗較佳。編織組織 爲圓編織之平組織、兩面組織、精製組織、雙反面組織或 此等織變化針織物、以經編者有特里科針織物、羅素斜紋 針織物等，沒有特別的限制。編織組織爲特里科針織物時 例如半組織、逆半組織、雙梳櫛經平組織、雙梳櫛經緞組 織，爲羅素斜紋針織物時例如有彈性針織物、半彈性針織 物、緞紋針織物、，經編針織物等。 -27- 1277668 彈性紗與非彈性纖維亦可使用作爲被覆紗與合撚紗、複 合紡績紗等之複合紗，以及可使非彈性纖維與聚胺甲酸醋 彈性紗之裸紗交織。視其所需亦可使複合物與非彈性紗交 織。爲降低加工費用時’以裸紗父織較佳。而且，爲降低 針織物之橡膠觸感或吸濕時之黏腻感時，針織物之表層以 非彈性纖維被覆較佳。此時，爲充分發揮吸濕發熱、放濕、 抗菌、消臭性能及針織物之伸縮性能時，彈性纖維之含有 率以10重量％以上較佳。更佳者爲20〜50重量％。若大於 5 0重量％時，不僅經濟性不佳，且會有柔軟性、膨脹度等 質感降低的情形，故不爲企求。 本發明之針織物於初期與洗濯1 0次後之吸濕發熱特性 的溫度差小於1 °C，若小於1 °c時係指具有洗濯耐久性，且 可維持1 0次洗濯後之吸濕發熱特性。 本發明之針織物適合使用於緊身內衣褲，於上述彈性樹 脂中由於含有上述局吸濕性有機微粒子，故可形成具有高 伸縮性能或吸濕發熱、放濕吸熱、制電性能之穿著舒適性 能、以及藉由消臭抗菌效果之衛生功能、藉由pH値緩衝性 能之保濕功能的多功能伸縮針織物。本發明包含緊身內衣 褲之發明。 其次，說明有關本發明之褲襪。 本發明褲襪之特徵係爲具有吸濕能，吸濕時具有發熱、 加溫效果。首先，有關本發明褲襪穿著時之溫濕度變化， 與適用於緊身內衣褲之針織物大約相同。 本發明人等進行檢討藉由改變彈性紗中之高吸放濕性微 粒子濃度，感覺吸濕時褲襪穿著試驗之加溫效果，結果可 •28- 1277668 知以7 °C /分以上之昇溫能力較佳。更佳者爲9 °C /分以上。 受外部環境影響之外溫愈低時，昇溫能力愈高。 本發明之褲襪，就薄質、強度、伸長性及伸長回復性而 言以彈性紗與合成纖維紗之複合紗構成，或該複合紗與合 成纖維紗之假撚加工紗之交織針織物較佳。彈性紗以彈性 單紗較佳，合成纖維紗以合成單紗較佳。褲襪之表裡表面 以實質上合成單紗被覆較佳。此係避免彈性紗與肌膚直接 接觸，與肌膚面之平滑性佳，故可滿足作爲褲襪之較佳特 性。複合紗雙方爲單紗時，可提高透明性、與提高強度、 提高穿著耐久性，故較佳，合成單紗以聚酯或耐龍較佳。 就吸濕性、耐久性而言合成單紗以耐龍單紗更佳。該複合 紗之總纖度實質上褲襪部用爲30〜80旦尼爾，足部用爲10 〜50旦尼爾較佳。 初期與1 0次洗濯後之吸濕發熱特性差距有洗濯耐久 性、且小於1 °C，係指即使10次洗濯後仍可維持體感之吸 濕發熱特性。本發明之洗濯係指使用纖維評估技術協議會 之標準洗劑、以JIS-02 1 7 - 1 03法爲基準之洗濯。 含有高吸放吸性有機微粒子之彈性紗以含有20重量％以 上構成針織物較佳，若小於該範圍時，吸放濕特性不足、 會有氣味，故不爲企求。而且，絲襪之緊密感不足，不爲 企求。更佳者爲25〜40%。爲褲襪時褲子部與足部一般各 以不同的紗構成。兩者以同紗構成時沒有問題，惟僅一方 使用含有該吸濕性有機微粒子之彈性紗時，係指僅該部分 之針織物中含有該吸濕性有機微粒子之彈性紗的構成比 例。 -29- 1277668 如此使環境變化而定重複使吸濕發熱與放濕吸熱作用之 針織物藉由任意分別使用於褲子部及足部，可視季節及環 境而定設計褲襪。例如夏季用褲襪係藉由僅足部含有發熱 •吸濕性有機微粒子之彈性紗，可得具有淸爽感之涼爽褲 襪；冬季用以褲子部及足部雙方皆使用較佳。 本發明之褲襪以具有至少一種選自於銨、醋酸及異戊酸 之消臭率爲70%以上的特徵較佳。此等成分係爲財團法人 之纖維評估技術協議會作爲汗臭之臭氣成分者，若具有消 除此等成分之臭味性能時，特別是對上述3種中任一成分 而言具有消臭能力時，容易具有消除發汗後之臭氣性能， 該性能以70%以上爲目標。因此，若小於70%時該性能不 充分、無法說具有消臭性能。較佳者係消臭性能爲85 %以 上、更佳者爲90%以上。 本發明之褲襪以洗濯前與洗濯後酯少一種選自於銨、醋 酸及異戊酸之消臭率爲70%以上較佳。習知市售的絲襪於 形成製品後，附著有消臭成分、幾乎完全是後加工品，此 等由於洗濯耐久性不佳，例如雖初期具有消臭能力，惟洗 濯後其消臭性能惡化。本發明之絲襪採用的較佳彈性紗， 由於在纖維表面及內部與纖維一體化，故即使洗濯、其性 能仍完全不會惡化.。洗濯後消臭率之更佳範圍爲8 0 %以 上，最佳者爲8 5 %以上。 本發明之絲襪以摩擦帶電壓爲2500V以下較佳。若摩擦 帶電壓大於2500V時，穿著裙子時容易黏覆其上，特別是 低濕度的冬季裡穿著時容易有不舒適感。較佳範圍爲2000V 以下、更佳者爲1 500V以下。 -30- 1277668 本發明之絲襪以帶電壓之半衰期爲5 0秒以下較佳。與摩 擦帶電壓同樣地該帶電壓之半衰期係爲評估糾纏容易性之 篸數’該數値爲5 0秒以下時，例如藉由左右絲襪與裙子等 與外部摩擦而引起靜電，由於帶電壓之減少速度快，故不 容易有不舒適感。而若大於5 0秒時’特別是在低濕度之冬 季裡穿著時，容易感到不舒適感。較佳者爲3 0秒以下、更 佳者爲1 5秒以下。 其次，說明本發明之織物。首先，主要說明有關含有很 多長纖維之織物（以下稱爲長纖維織物）之發明。 本發明之長纖維織物係爲含有非彈性纖維與上述彈性纖 維之複合紗的織物，以定荷重伸長率爲1 5 %以上、定荷重 伸長回復率爲3 5 %以上、吸濕時織物表面上升溫度爲1 <>c以 上之織物較佳。 於本發明中定荷重伸長率、定荷重伸長回復率及吸濕時 織物表面上升溫度，係爲各藉由下述方法測定之値。 長纖維織物之伸長特性係爲衣料、特別是運動衣料所要 求的重要特性。本發明之織物爲得到容易運動的衣料時， 定荷重伸長率爲15%以上、較佳者爲20%以上。定荷重伸 長率之上限爲不使保形性及伸長回復降低時以約4〇 %較 佳。 而且，本發明之長纖維織物在不損及美觀下，定荷重伸 長回復率爲35 %以上、較佳者爲60 %以上。定荷重伸長回 復率之上限沒有特別的限制，約爲95 %。 此外，本發明之長纖維織物係吸濕時織物表面上升溫度 爲1 °C以上、較佳者爲2°C以上。吸濕時織物表面上升溫度 •31- 1277668 愈高愈佳，通常直至5 °C左右、即充分。藉由使吸濕時織 物表面上升溫度上述範圍，穿著時會有暖和感。 爲含上述非彈性纖維與彈性纖維之複合紗之織物，定荷 重伸長率爲15%以上、定荷重伸長回復率爲3 5%以上、吸 濕時織物表面上升溫度爲1 °C以上之織物，可藉由下述方 法製得。換言之，爲含有5重量％含非彈性纖維與高吸放濕 性微粒子之彈性纖維的複合紗之織物，且藉由使製作複合 紗時之牽引率、織組織及織密度適性化，可得上述數値範 圍之織物。 定荷重伸長率及定荷重伸長回復率可藉由調整複合紗製 作時之牽引率、織組織及織密度、以及織物中複合紗之含 量予以調高或降低。而且，吸濕時織物表面上升溫度可藉 由調整彈性紗中微粒子之含量及織物中複合紗之含量予以 提高或降低。 構成紗之織度係視構成材料之種類或用途而不同，彈性 紗之繊度通常爲20〜lOOdtex、較佳者爲30〜50dtex。若爲 上述範圍時，所得織物之伸長特性、回復特性佳。 於本發明之長纖維織物中，非彈性纖維係指以JIS L1 01 3(2000)(定速伸長形試驗）所規定的斷裂伸度爲1〇〇 %以 下之纖維。非彈性纖維之種類沒有特別限制，可使用習知 纖維。該習知非彈性纖維例如聚醯胺（耐龍等）、聚酯、維 尼龍、丙烯酸、聚乙烯、聚丙烯之合成纖維；雷縈、銅胺 之再生纖維；乙酸酯、普羅米克絲之半合成纖維；絲綢之 天然纖維等。 就滿足運動衣料所要求的強度而言，特別是由聚酯、聚 -32- 1277668 醯胺（耐龍等）所成單紗較佳。非彈性纖維可以單獨1種使 用或2種以上混合使用。 由非彈性纖維所成紗之纖度通常爲10〜1〇()dtex、特別是 20〜50dtex較佳。 非彈性纖維就可得大體積' 膨脹感、暖和感而言，以施 有大體積加工之纖維較佳、更佳者爲假撚體積加工紗。 複合紗之形態可採用作爲彈性纖維之複合型態的習知形 態’沒有特別限制。該習知複合紗係使彈性纖維以適當牽 引倍率供應，藉由與非彈性纖維同時引取的狀態下撚紗、 所得的層紗線等。特別是以被覆紗線較佳。就藉由非彈性 纖維以提高被覆性以避免因彈性纖維露出而切斷，同時可 降低布帛間之摩擦而言，使用中空軸式被覆機所製造的捲 取被覆紗線（單被覆紗線）更佳。 複合紗之撚數例如500〜1 200T/m、較佳者爲600〜 1 2ΟΟΤ/m。若撚數在上述範圍時，可滿足複合紗之伸長回復 特性、且因彈性纖維之表面露出而降低「針向」之問題。 ，彈性纖維與非彈性纖維之使用比例以重量比、彈性纖 維：非彈性纖維之比例通常爲1 : 2〜1 : 8，較佳者爲1 : 3 〜1 : 5 〇 本發明之長纖維織物中爲可得實用上充分的吸濕發熱效 果時，以含有5重量％以上之上述複合紗較佳。特別是含有 20重量％以上較佳、更佳者爲25重量％以上。織物可使用 100%該複合紗作爲紗者，惟就保持穿著時之舒適性而言以 30重量％較佳。若複合紗之比例在上述範圍時’穿著時容 易感到吸濕發熱效果。 -33- 1277668 除上述複合紗外存在有構成長纖維織物之纖維時，該材 料沒有特別的限制，可使用合成纖維‘、半合成纖維、再生 纖維、天然纖維。而且，紗形態可以爲單紗或紡績紗。複 合紗外之纖維可以爲非彈性纖維、亦可以爲彈性纖維，就 質感及觸感而言以使用非彈性纖維之長纖維較佳。複合紗 外之纖維可以單獨1種使用或2種以上組合使用。 上述複合紗外之纖維爲運動服用織物時，以聚酯系或/ 及聚醯胺系單紗（特別是非彈性紗）較佳。爲薄質、布表面 爲平滑之布帛時，可使用平坦紗，此時爲伸縮性稍微不佳 的布帛。必須爲稍厚、伸長率大的布帛時，上述複合紗外 之紗以使用大體積加工紗較佳。特別是以使用聚酯系單紗 或聚醯胺系單紗之假撚加工紗（特別是1段加工紗）較佳。 而且’要求美觀性時除上述複合紗外之紗以使用潛在紗 長差混纖紗較佳、更佳者爲由聚酯單紗所成的潛在紗長差 混纖紗。使用潛在紗長差混纖紗時，藉由使製造後之織物 使用氫氧化鈉等輕輕地減量加工，可提高質感之牽引感及 膨脹感。潛在紗長差混纖紗可使用2種以上具熱收縮差之 單紗混纖之異收縮混纖紗、或與藉由熱處理收縮之單紗伸 長的單紗混纖之自發伸長混纖紗。 而且，爲內衣褲或一般衣料用織物時，複合紗外之基本 紗以使用由聚酯或耐龍所成的平坦紗較佳。 彈性複合紗可使用經紗及緯紗雙方予以交互配列，或經 紗或緯紗一方由彈性複合紗所成者、另一方由非彈性紗所 成者。爲前者時可得2方向伸縮織物，爲後者時可得1方 向伸縮織物。 -34- 1277668 由於本發明之長纖維織物兼具有吸濕發熱性質與伸縮 性，故適合使用作爲運動服、內衣褲、一般衣料、防寒衣 之內襯或防寒外衣（可自由脫落的裏布）等。 使用本發明長纖維織物之衣料種類，沒有特別的限制， 由於兼具有吸濕發熱性質與伸縮性，故適合作爲運動服、 內衣褲、防寒外衣、防寒衣之內襯、一般衣料等。爲運動 服時，特別是最適於作爲屋外服之工作服的衣料。 具體而言，運動服例如網球衣、滑雪衣、慢跑衣等之上 衣或褲子等。此等之中以使用例如組合彈性蒗合紗與非彈 性聚酯假撚加工紗之織物爲宜。 一般衣料例如襯衫或女用襯衫之中間衣、褲子、裙子、 外套之外衣等。此等中可使用組合絲綢或具吸汗性之特殊 單紗所成的細纖度之織物（中衣用等）、或組合彈性複合紗 與非彈性之聚酯單紗之織物（外衣用等）、或組合彈性複合 紗與異收縮混纖紗之織物（外衣用等）等。組合彈性複合紗 與異收縮混纖紗之織物不僅可使用於夾克之一般衣料的外 衣，且可使用於網球用夾克、高爾夫球用夾克之運動用外 衣等廣泛用途。 貼身衣服例如襯衫、短褲等。可使用此等中組合此等絲 綢或具有吸汗之特殊單紗所成細纖度紗之織物等。 外套或滑雪用防寒衣物之內襯或防寒外衣中可使用組合 彈性複合紗與非彈性聚酯單紗之長纖維織物。 其次，說明有關本發明主要的大多包含短纖維之織物（以 下稱爲短纖維織物）。惟彈性纖維以長纖維較佳。 本發明之短纖維織物係爲含有非彈性纖維與上述談形纖 -35- 1277668 維之複合紗纖維，定荷重伸長率爲1 5 %以上、定荷重伸長 回復率爲35 %以上、吸濕時織物表面上升溫度爲0.5 °C以 上、布帛表面以10條/cm2之密度具有長度lmm以上之絨 毛的織物較佳。 於本發明中定荷重伸長率、定荷重伸長回復率、吸濕時 織物表面上升溫度及布帛表面之絨毛密度係各爲藉由下述 方法測定的値。 短纖維織物之伸長特性係爲衣料、特別是運動衣料所要 求的重要特性。本發明之短纖維織物爲製得容易活動的衣

A technique for improving the water absorption of the polyurethane-based elastic property is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. The physical strength, the processability, the non-ionic water-absorbent polyurethane yarn, and the melt-spun yarn which are excellent in affinity with a high bio-affinity are disclosed, however, the water absorption rate is 200% or more and the fiber composition is high. The fiber has a high water absorbing property, and the fiber swells during washing or sweat absorption, and exhibits a slight warm feeling. Therefore, when it is used as a clothing material, there is a problem in Japanese Patent Laid-Open Publication No. 2000-96. In the polyalcohol component of the bulk polymer, a polyalkane of a hydrophilic polyalcohol is used to improve the hygroscopicity of the polyurethane elastic fiber. The problem with U.S. Patent Publication No. 1 1 - 8 1 046 is disclosed to reveal that the effect of using the garment on the texture without affecting the texture can be reduced. Among the methods for increasing the moisture permeability of the polyurethane fiber, a method of mixing a high-molecular compound includes, for example, an acrylic polymer, a polyethylene-based polyamine-based polymer, and a highly water-absorptive polyurethane-based polymer. The presence of such superabsorbent polymers locally has a problem of lowering the stability of the physical yarn. In addition, in general, the superabsorbent poly-crosslinking, expansion due to water absorption, introduction of the hydrophilic polyalcoholic polyurethane elastic fiber, expansion, coating or slag residue adhere to the yarn joining wire, etc., and yarn breakage Or a poor quality question. Further, in recent years, the heat resistance of the polyurethane-based elastic fibers has been high, and in particular, polyurethane-based elastic fibers which have been interwoven with high-temperature and high-pressure dyes have been demanded since ancient times. In the case of the above-mentioned requirements, H. Patent Publication No. Hei 5-186557, and JP-A No. 5-86557 have a high water absorption method. The molecule itself is produced on the surface of the fiber. The invention discloses a polyether polyol which can have the following water-absorbing polypolymer, etc., which can be used for the disintegration, but the polyester which is not required to be the same, and which is accompanied by the post-processing requirement The technique of using a polyurethane solution to form a polyurethane polymer by molding by heat treatment to increase the polyurethane elastic fiber is disclosed in Japanese Patent Publication No. 102035. Heat resistance techniques are known. However, the polyurethane-based elastic fiber of such a technique can improve the heat resistance to the heat treatment in the post-processing, but it is difficult to control the throughput depending on the purpose, and the handleability is poor, and the post-process passability is problem. Further, when the hydrophilic group is introduced into the polyol component, the heat resistance of the heat treatment in the post-processing is lowered, and it is difficult to be interlaced with the polyester fiber which is required to be dyed at a high temperature and high pressure. Next, a conventional technique relating to fabrics will be explained. A fabric made of a non-stretchable fiber such as a polyester fiber, a polyamide fiber, or a cellulose fiber, and a polyurethane elastic yarn can be used for pantyhose or short stockings, a bra, and a rhythm because of excellent stretchability. Other stretchable bags such as uniforms such as basic clothes or aprons, sportswear, ski pants, stretch trousers, etc., stretchable tights, base fabric for stretchable tape, support medical use, or telescopic shoes Base cloth and other uses. In particular, in the use of underwear for women, due to appropriate stretchability and thinness, composite knitting of elastic yarns such as polyurethane and Nylon is the mainstream. However, due to the poor moisture permeability characteristic of synthetic fibers, there is a problem of sultry sensation, and the method for solving the sultry feeling is in addition to the above-described use of hygroscopic polyurethane, for example, the Japanese Patent Laid-Open No. Hei 9-228 1 55 Japanese Laid-Open Patent Publication No. Hei 9-256278 discloses an absorbent hygroscopic yarn which is improved in moisture absorption characteristics of nylon fiber. The comfort required for the close-fitting clothing is evaluated by the humidity control effect and the moisturizing performance. It is to suppress the effect of self-heating, heating effect and the feeling of cold after the wearing of 1277668 sweat. Acrylic moisture absorption is disclosed in the publication No. 9- 1 5 8040 or JP-A-00-303 353 j. , 〆, -〆 **,,, hot fiber. However, 'Weiweiwei is mainly short fiber, because the mechanical properties are slightly poor, it is not easy to produce a spun yarn or a thin fabric, and it can be formed by compounding with an urethane-based elastic yarn to form an elastic yarn. The law is satisfying. Further, for example, Japanese Laid-Open Patent Publication No. 2001-38375 proposes to fix the acrylic moisture-absorbing and heat-generating resin particles to the surface of the nylon or polyester fabric by resin bonding or graft polymerization in post-processing. The above method is only in the presence of hygroscopic particles in the surface layer, and there is a problem of stickiness when moisture absorption or a problem of lack of durability of washing or texture hardening. Next, a description will be given of a conventional technique relating to stockings. Since the emergence of Nylon yarn, stockings have been widely used as a clothing material to improve the beauty of women's feet, and the appearance of pantyhose has extended its use. In addition, by increasing the popularity of the hobby, it is necessary to differentiate products that are more transparent and more flexible. One of the strong supportive stockings, the use of polyurethane elastic fiber and the yarn of the surface yarn of the dragon yarn, is still in the mainstream. In the case of a stocking that is high in strength, thin in quality, and excellent in wearing durability, it is a treasure, but in the case of thinness, there is a disadvantage of lack of heat in the case of severe cold. Moreover, due to the low hygroscopicity, it is sought to improve the sweltering situation during sweating. In addition, the sweltering situation has an odor in the shoe, which is one of the troubles of women. There are many fibers with excellent hygroscopicity in synthetic fibers, which are generally low in strength and thin in quality, and cannot be used in the use of stockings for durability. The single yarn used in stockings is mainly resistant to dragons or polyesters, especially Nylon. In the synthetic fiber, the moisture content is high and the strength is high, so the nylon single yarn is used. However, there are many problems in the cold or when it is hot. The use of severe cold is thicker, and many other young women are dissatisfied with the appearance of 1277668. On the other hand, when you are not wearing hot stockings when you are hot, you often wear them when you pay attention to the appearance and tightness. In recent years, the stockings called the support type have stronger requirements, and the elastic yarns such as urethane and the composite yarn of Nylon are the mainstream, but the use of the above-mentioned nylon resistant fibers is used for the purpose of solving the sultry feeling. A moisture-absorbing and durable nylon-resistant yarn with improved wet properties, or a moisture-absorbing polyurethane using the above-mentioned hygroscopic polyurethane, is proposed to improve the moisture absorption and moisture-absorbing stockings until the current moisture absorption or antibacterial, deodorizing The effect is still insufficient. The moisture absorption and heat-generating effect is known as a conventional cotton or wool fiber system, but the same as the above-mentioned type is still not suitable for a woman who desires thinness and aesthetics. In view of such a situation, for example, in the publication of Japanese Patent Laid-Open Publication No. Hei. No. 000 b丨31, it is proposed to fix the moisture-absorbing heat-generating resin granule resin to the composite of Nylon and polyurethane elastic yarn in the post-processing. The silk yarn method consists of the yarn, but the moisture absorbing particles are present in the surface of the dragon-resistant yarn, and there is a problem of stickiness or insufficient washing durability when moisture is absorbed, and the texture is hardened. Secondly, the prior art of long fiber fabrics is mainly explained. In other words, exercise usually involves warming the muscles or joints before starting the exercise to prevent injury, improve exercise, and warm-up exercises. Especially in the cold weather, it is extremely important to warm up in the outdoor sports. At this time, the warm-up clothes worn by the sports players have to be warmed up for a long time because the raw materials of the known materials have a heat preservation effect, but have no heating effect. In order to avoid this situation and to warm up the body effectively in a short period of time, it is more expensive to wear when wearing a thick material that impedes the lotus movement. Although a heat source such as a furnace can be placed in the clothes, -10- 1277668 can only be locally warmed under the heating, so that the effect is limited and the movement is hindered. In addition, golf balls or skis that are used for long periods of time outside the house in winter are expected to have a warming effect. Moreover, in addition to sportswear, winter clothing or underwear is also required to have a warming effect. Here, the fiber having a hygroscopic property and a temperature-regulating action is, for example, a crosslinked acrylic fiber described in Japanese Laid-Open Patent Publication No. Hei 9-5 9 纟. However, 'crosslinked acrylic fibers are not only not suitable for the stretchability of sportswear' and do not consider easy mobility. In addition, it is mainly related to short-fiber fabrics, that is, overalls worn in the workplace. In general, clothing materials are required to have thermal insulation effects or decorative effects, and the protection effect of the body is sought. For example, work clothes for outdoor work are also required to prevent injuries, or to block ultraviolet rays and protect the skin. In addition, the medical uniforms or the uniforms required for the experiment are required to prevent body contamination due to bacteria and the like. In addition, the overalls are required to properly maintain the temperature and humidity in the clothes, and can be easily handled, especially in the winter work clothes outside the house, in order to have the effect of protecting the skin and releasing sweat from the clothes. When it is necessary to have a moisture absorption or water absorption function, the cotton cloth is mainly used, but since the cotton fiber does not have a quick-drying property, it may be sticky or cold when working. Although the wool fabric has excellent heat preservation effect and moisture in the clothes to the outside, the mechanical durability of the overalls is not good. Here, the above-mentioned crosslinked acrylic fiber type having a hygroscopic property and a temperature regulating action is known. However, the crosslinked acrylic fiber is not suitable as a stretch for work clothes or the like, and is not easy to move. </ RTI> -11- 1277668 The first object of the present invention is to provide an elastic fiber suitable for a fabric having high heat retention, comfort, and aesthetics, and to provide an excellent processability for post-processing. An elastic fiber that is heat-resistant and can quickly remove water vapor generated by sweating during exercise, and has no sultry elasticity. A second object of the present invention is to provide a woven fabric which is excellent in hygroscopic heat-generating property, excellent in heat retaining property by heat generation, and excellent in stretchability, and is particularly excellent in warming effect by moisture absorption, and warm-up during exercise such as exercise.

The invention is detailed in the following. First, the invention of the elastic fiber is described. The elastic fiber of the present invention preferably has a maximum temperature rise of 2 ° C or more when moisture absorption and/or water absorption. More preferably, it is above 3 °C. The elastic fiber having this characteristic is thin and can impart high moisture retention to the fabric. However, when the maximum temperature rise during moisture absorption and/or water absorption is too high, in addition to the increase in yarn breakage during yarn making, the use of the actual braid causes an excessively high temperature rise, so it is not required, usually elastic fiber. The maximum temperature is preferably less than 1 〇 °c. In addition, the elastic fiber of the present invention has the above-mentioned heat-generating property, and the moisture absorption rate of 20 ° C X 65% RH is 0. 5% or more, 20 ° C X 95% RH moisture absorption rate 1. More than 5% is preferred. More preferably, the moisture absorption rate is 1 at 20 ° C X 65% RH. 0~ 5. 0%, 20 ° C X95% RH moisture absorption rate of 2·0~15·0%. The elastic fiber having the above characteristics is not only as thin as possible, but also absorbs sweat as effectively as possible, so that even if the body temperature is drenched when the temperature is warm, there is no discomfort, and it is warm and does not have Highly comfortable with a sense of sultry heat. In addition, it can also relieve the cold feeling when sweat is cooled after sweating. -17- 1277668 The elastic fiber of the present invention has a moisture absorption ratio of 20 ° C X 65 % R Η and 20 ° C X 95% RH of preferably 1.0% or more, more preferably 2. 0% or more. This number indicates the ability to absorb sweat, and the higher the number, the higher the ability. Next, the heat resistance of the polyurethane-based elastic fiber of the present invention will be described. First, the dry heat fixing property of the polyurethane elastic fiber of the present invention is based on the following measurement method, PSD (dry heat setting rate after 100 minutes of elongation and dry heat of 190 ° C for 1 minute). More than 60% is preferred. If the number is less than 60%, the dimensional stability of the texture in the pre-fixing process is not good, so it is not desirable. Then, the moist heat fixing property of the polyurethane elastic fiber of the present invention is measured by the following measurement method, PSW (within 60 minutes under 100% elongation, moist heat, and temperature rise from 40 ° C to '13 (continuous after TC) It is preferable that the moist heat and the heat-heat setting rate after heat treatment at 130 ° C for 60 minutes are 75% or less. The number of lanthanum indicates the heat resistance in the dyeing process, and the heat resistance is more excellent as the number is higher. When the PSW is more than 75%, it is not easy to be interlaced with the polyester fiber which must be dyed at a high temperature and high pressure, and the elastic repellency is lowered, so it is not desirable. Since the elastic fiber is generally not exposed on the surface of the fabric and exists in the interior of the cloth for clothing. Therefore, the elastic fiber generates heat from the inside of the cloth when it is heated, and the same effect of the heat-generating body covered by the heat-dissipating material can be achieved, the heat-insulating body can be effectively insulated, the heat-receiving property can be obtained, and the high comfort can be obtained. The inelastic fiber which is exposed to the surface of the cloth can be obtained. When the heat is generated, the part that is exposed on the side of the anti-human body has a poor cooling effect, and when the part of the human body is heated, the comfort is lowered, so that it is not required. Further, when the moisture is absorbed, the adhesive is used to separate the heat generating agent, etc. The method of adhering to the surface of the fabric or containing the fibers on the exposed surface, in addition to easily impairing the texture, is insufficient in the durability of the washing during the separation, and is not desirable. In the general use method, the elastic fiber rarely exposes the fabric. Surface, -18- 1277668 has the advantage of not damaging the texture. The inner part of the elastic fiber is preferably a substance containing moisture absorption. First, the method of imparting hygroscopicity is to polymerize the raw material of the high-absorption and moisture-releasing fine particles in the elastic fiber. Spinning is extremely effective. Typical examples are polyurethane-based elastic fibers. Spinning can be carried out by any method of yarn, wet spinning or melt spinning. High-absorption particles can be used in organic systems. And/or inorganic ones, for example, polyacrylic microparticles, polyethylene polymer microparticles, polyamine polymer micropolyurethane polymer microparticles, porous cerium oxide microparticles, aqueous cerium oxide microparticles, and the like. In order to prevent physical properties from being lowered, and the spinning and processing passability is good, the particle diameter is 20 μm or less, preferably 10 or less, more preferably 5 μm or less, and most preferably 2 μm or less. For the above purpose, in the spinning process, the high absorption and desorption is required to be slightly dispersed in the fiber. If the particle size is larger than 20 μm, the mixture is added after mixing, and the surface of the fiber may be smeared due to the spinning. The reason why the yarn is broken after the cutting or the residue is adhered to. However, if the average particle diameter is too small, the aggregation tends to occur, and the dispersion of the polyurethane elasticity is not good, so it is preferably 0. 1 μm or more. Further, the particulate form is not particularly limited, and may be a spherical shape, a slightly flat spherical shape, or a shape other than the shape. The high moisture absorption and moisture release fine particles are preferably 2% by weight or more for the polyurethane elastic fiber. The better is 0. More than 5 wt%. If the weight is %, it lacks hygroscopicity, so it is not desirable. However, if the content is too large, the yarn-spinning property at the spinning stage is lowered, and the yarn breakage is large, so that the weight is preferably 50% or more, and more preferably 48% by weight or less. , heat added mixed elastic fiber dry k-wet wet micro-polymer particles, sub-, pro-workability I 1 0 μιη system for particle partial particle partial processing, the shape of the particle fiber inner shape, etc., at 0 · 2 In the case where the amount % is 1277668, the degree of swelling of the high moisture absorption and desorption fine particles used in the present invention is preferably 2 Ο 以下 % or less, more preferably 100 % or less. When the degree of expansion is more than 200%, the polyurethane elastic fiber itself expands due to moisture, and causes yarn breakage and poor quality due to residue adhesion when the surface layer is coated or knitted. The smaller the degree of expansion of the high-absorption and moisture-releasing fine particles, the better. In the polyurethane-based elastic fiber of the present invention, the expansion due to moisture absorption not only makes the high-absorbency and moisture-releasing organic fine particles small, but also the polyurethane-forming polymer which forms the fibers hardly absorbs moisture. In the case of expansion, there is little problem in the post-processing in which the residue adheres to the yarn-bonding wire or the like, or the quality is poor. The high moisture absorption and desorption microparticles used in the present invention have a high moisture content at 20 ° C X 65 % RH. 'The high moisture absorption and dehydration organic microparticles of the non-biopolymer are preferred. The better chemical composition is as follows. The moisture content of the high moisture absorption and dehydration organic fine particles of 65 C R % is preferably 30% or more. The better is more than 35%, and the best is 40% or more. In the conventional microparticles having hygroscopicity, the highest hygroscopicity is wool powder or chitin powder, and the moisture content of 20 t: X 65 % RH is 15% or more. Further, the polysaccharide-based fine particles or protein-based fine particles such as starch or cellulose, silk, and collagen are 8 to 12% smaller than the above-mentioned wool powder or chitin powder. The other urea resin-based or melamine resin-based powder has a water content of 30% or more at 20 ° C X 65 % RH, so it is not required, and it is good in preventing the physical properties of the elastic fiber from being lowered, and the spinning workability and the post-processing passability are good. In the case of the fibers, the particle size of the particles is 20 μm or less, preferably ΙΟμηη or less, more preferably 5 μm or less, and most preferably 2 μm or less, and the content is 0. 2 to 50% by weight is preferred. If the content is lower than the range, sufficient effects cannot be obtained, and if the elastic fiber is produced at a high level, defects such as yarn breakage are induced. -20- 1277668 When the elastic fiber of the present invention contains the high moisture absorption and dehydration organic fine particles formed by the non-raw system polymer, the hydrophilic group of the high moisture absorption and release organic fine particles has a salt type carboxyl group and a salt type sulfonate. Acid group, salt type phosphate group, salt type phosphate group, etc., salts include alkali metals such as Li, Na, K, etc., alkaline earth metals such as Mg, Ca, and Ba, and other metals, ammonium, and amines such as Cu, Ag, and Mn. Salts such as organic cations may also contain an acidic group in addition to the salt type. The highly absorbing and dehydrating organic fine particles are introduced into the crosslinked structure by treatment with hydrazine, divinylbenzene or triallyl isocyanate in an acrylonitrile-based polymer containing 50% by weight or more of acrylonitrile, and the remaining nitrile group is used. Adding water to chemical decomposition into a salty carboxyl group to have l. Ommol/g salty carboxyl group is more preferred. Although not particularly limited, for example, (a) is increased by a nitrogen content of 1·〇~15 in an acrylonitrile-based polymer containing 85% by weight or more of acrylonitrile. After the treatment of 0, the crosslinked framework is introduced, and the remaining nitrile group is chemically converted into a salty carboxyl group by hydrolysis, so as to have l. Acrylic metal-transformed particles of 〇mmol/g of a salt-based carboxyl group, (b) introduced into a crosslinked structure by treatment with divinylbenzene or triallyl isocyanate, and remaining in an acrylic acid-based polymer containing 50% by weight or more The nitrile group is chemically converted into a salt residue by hydrolysis to form a residue of 2. Ommol/g salt type carboxylic acid-based metal conversion particles of a carboxyl group. The amount of salt carboxyl group is 4. 0~10. Ommol is better. The method for producing the high-absorption and moisture-absorbing organic fine particles can be produced, for example, by the method described in JP-A-8-2256190. Since the hygroscopic heat-generating effect of the elastic fiber of the present invention is mainly due to the salt of the salt type, the product of the salt-type carboxyl group concentration (mm ο 1 / g) and the fine particle concentration (% by weight) in the fiber is usually 40 to 8 Torr, preferably. The ratio is 45 to 75, and the concentration of the fine particles in the fiber is preferably fixed. If the content of the fine particles in the elastic fiber is in the above range, the body can feel a feeling of sufficient warmth and does not cause the problem of being difficult to spin due to yarn breakage - 21-217386. These metal-converting particles are crosslinked acrylic polymer microparticles, and monomers for the acrylonitrile-based polymer of the starting microparticles, such as a halogenated vinyl group, a halogenated vinylidene group, an acrylate, or a methacrylate, are used. a sulfonic acid-containing monomer such as a styrenesulfonic acid or a salt thereof, a carboxylic acid-containing monomer such as acrylic acid or a salt thereof, acrylamide, styrene, vinyl acetate or the like. The elastic fiber containing the high moisture absorption and dehydration organic fine particles has both good heat and hygroscopicity. When the high moisture absorption and dehydration organic fine particles are added to the polyurethane elastic fiber, it has remarkable heat generation and hygroscopicity as compared with the case of the inelastic fiber added to the ester or the nylon, and the polyurethane elasticity. The physical properties such as the strength of the fiber are extremely lowered. Although the reason is not clear, it is presumed that the surface of the fiber is easily fainted. Further, the highly hygroscopic organic fine particles have excellent antibacterial properties and deodorizing properties, and particularly have an additive price of elastic fibers used in stockings or bodysuits. The elastic fiber of the present invention refers to a fiber having a rubber elastic action from a social point of view, for example, at least 50% or more, more preferably 1% by weight or more, and a recovery ratio of 20% or more. The response rate here refers to the length of the reduction by the reply for the entire extension. For example, a polyurethane-based elastic fiber having particularly excellent stretchability is exemplified. The polyurethane polymer used in the elastic fiber of the present invention may be such that an intermediate polymer having an isocyanate group at both ends of a polyalcohol and an excess of a mole of a diisocyanate compound is dissolved in N, N, -dimethyl A compound obtained by reacting a diamine compound in an inert organic solvent such as vinylamine or dimethyl sulfoxide. The above polyhydric alcohol is not particularly limited, and is, for example, a polymer diol. Specifically, for example, a polyether diol selected from the group consisting of polyoxyethylene glycol, polyoxypropylene glycol, polyoxytetramethylene glycol, -22-1277668 polyoxypentaethylene glycol, and polyoxypropylene tetramethyl glycol. Two or more kinds of adipic acid, sebacic acid, maleic acid, itaconic acid, azelaic acid and one of the acid acids, one or two or more kinds of ethylene glycol, 1,2-propylene glycol, 1, Polyester diol obtained from alcohols such as 3-propanediol, 2,2-dimethyl-anthracene, 3·propylene glycol, hydrazine, 4-butanediol, 2,3-butanediol, hexamethylglycol and ethylene glycol Polylactone diol such as poly-ε_caprolactone and polyvalerolactone, polyester guanamine diol, polyether ester diol, polycarbonate diol, and the like. The diisocyanate compound is not particularly limited as long as it is an aliphatic, alicyclic or aromatic diisocyanate compound. For example, methyl bis (heart phenyl isocyanate), methyl bis (3-methyl-4-phenyl isocyanate), hydrazine, 4 phenyl tolylene diisocyanate, 2,6-tolyl diisocyanate, m _ and p-phenylene diisocyanate, and p-xylylene diisocyanate, decyl bis (4-cyclohexyl isocyanate), hydrazine, 3 _ and hydrazine, 4 _ cyclohexyl diisocyanate, trimethyl Diisocyanate, tetramethylammonium diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, and the like. The amine compound of one of the chain extenders is not particularly limited, and is, for example, ethylenediamine, propylenediamine, trimethyldiamine, hexamethylenediamine, anthracene, 2-cyclohexanediamine, anthracene, hongcyclohexanediamine, 1, 4-cyclohexanediamine, hydrazine, and the like. The elastic fiber of the present invention can use a surface layer yarn or a false twist yarn. When the composite elastic yarn is coated with an elastic fiber, it can provide long, high heat insulation and comfort. Further, the elastic fiber of the present invention can also be used for pantyhose. This application emphasizes the aesthetics of wearing and requires a thin cloth, so that the effects of the present invention can be particularly exerted. The interlaced raw material of the elastic fiber of the present invention may be any one of thermoplastic synthetic fiber, Tian-23-1277668 synthetic fiber, and recycled fiber. When it is a thermoplastic synthetic fiber, polyester fiber or polyamide fiber may be used, and when it is natural fiber, High wet modulus viscose fibers can be used for cotton and wool 'recycled fibers. The intertwining of the target material with the elastic fiber of the present invention is not limited thereto. For example, when the elastic fiber is generally coated with the target material during the interlacing, the polyester fiber or the like is coated on the elastic fiber to be used for the warp yarn and/or the weft yarn. Further, when interlaced with the target material, it can be directly pulled and woven with the target material, and woven with the covered yarn. The dyeing process of the obtained stretchable knitted fabric can be carried out by a general processing project in which the living machine is slackened, tempered, pre-fixed, dyed, dried, textured, and fixed. Next, a knitted fabric relating to the present invention will be described. The knitted fabric of the present invention is a highly stretchable knitted fabric composed of the above elastic yarn and non-elastic fiber, but the inelastic fiber of the present invention is a natural single fiber such as wool, cotton or silk, or a synthetic single yarn such as nylon or polyester. , fibers with a tensile elongation of less than 100%. The non-elastic yarn is substantially free of hygroscopic heat-generating organic fine particles, and the inner surface of the knitted fabric is preferably covered with inelastic fibers. The term "non-hygroscopic organic fine particle" as used herein does not exclude the amount of particles which are not more than the moisture absorption rate of the knitted fabric, and it does not matter if it contains a little. The blending ratio of the elastic yarn of the knitted fabric of the present invention is preferably 20% by weight or more of the knitted fabric in terms of moisture absorption and warming effect. It is preferable to keep the inner liner at the time of wearing, and it is preferably 50% by weight or less. Compared with cotton fiber or wool fiber, the elastic yarn of the present invention has a slow absorption and desorption rate and a high moisture absorption level, and as a result, heat generation and exothermic heat continue in a mild state for a long time, especially when the sweat temperature is stopped. Slow, with a sense of cooling after stopping the movement. In addition, the -24- 1277668 salt-type carboxyl group has various effects such as deodorization, bacteriostatic antibacterial, pH buffering, and electricity generation in addition to the hygroscopic heat-generating effect, and is a product having an ideal performance as a warm-up vest. In addition, since there is no bacteria to multiply under the shade, it is suitable as a swimsuit. The knitted fabric of the present invention has a surface temperature of more than 3 °C when the knitted fabric absorbs moisture. The heat generation during moisture absorption causes the knitted fabric to be dried at 70 ° C for 2 hours, and then adjusted to a temperature of 32 ° C and 70 % RH after adjusting the temperature in a desiccator-added drier for 8 hours or more. The surface of the knitted fabric was allowed to stand for 5 minutes on a heat meter to measure the surface temperature, and the maximum temperature was measured, and the difference from 32 ° C was used as the rising temperature. When the temperature is less than 3 °C, the somatosensory effect is lacking, and the higher the rising temperature, the better, about 10 °C. The elongation property of the knitted fabric is an important requirement. In order to improve the heat retention property, and to adhere to the body as much as possible without hindering the movement, the knitted fabric must have a constant load elongation of more than 50%, preferably. The elongation at break is 60 to 100% elongation. Further, in order to maintain the adhesion to the body, the recovery property is excellent, and the appearance is not impaired, the elongation recovery of the load-elongation elongation is preferably 50% or more. Preferably, it is 6 0 to 9 5 %. After the composite yarn is formed by mixing the elastic yarn and the non-elastic fiber, a method of knitting or a method of interlacing an elastic yarn and a non-elastic yarn is employed. However, when interlacing, the surface of the needle fabric is preferably not directly elastic. Since the surface of the absorbent fiber is sticky due to moisture absorption, it does not substantially absorb a large amount of moisture, and the skin does not feel the sticky feeling of the inelastic fiber. The method of forming the composite yarn is a method of composite spinning yarn or coated yarn. A method of forming a composite spun yarn, for example, in a spinning process of inelastic fibers in a roving drawing range in which the elastic yarn is supplied at an appropriate draw ratio to form a core-25·1277668 composite yarn. Specifically, for example, a method of forming an elastic yarn by supplying an elastic yarn at an appropriate draw ratio, and winding a non-elastic yarn thereon. For the former, wool, cotton, hemp, polyester staple fibers, and nylon short fibers can be used as the inelastic fibers. For the latter, silk, polyester single yarn, nylon single yarn, cotton and wool yarn can be used. It can also be used as a composite false twisted yarn for polyester single yarn and nylon single yarn. These composite yarns can be used alone or interwoven with other fiber yarns as a circular knit fabric, which has the advantage of a large elongation of the knitted fabric. The extension of the tissue system can satisfy the necessary conditions without any particular limitation. In the case of a knitted fabric, especially after the twist of the inelastic single yarn forming the needle, even if the elastic yarn is used in any twist, since the elastic yarn can be surrounded by the non-elastic single yarn to form the knitted fabric, the elastic yarn can be used naked. yarn. In this case, the non-elastic yarn may be a spun yarn, and it is preferable to use a single yarn in order to suppress the workability of the pile or the wind cotton. The knitted fabric of the present invention is suitable for use in underwear. A knitted fabric suitable for use in underwear, which is characterized by having hygroscopic energy and having heat generation and warming effect when absorbing moisture. This point is also the same in the invention of the stockings described below. First, the temperature and humidity changes of the knitted fabric of the present invention when worn will be described. The temperature and humidity of the present invention refers to the temperature and humidity of the air contained in the needle of the knitted fabric of the tights, and the change affects the comfort. When the body temperature rises due to the stimulation of exercise or the like, the body temperature is cooled and sweat is released from the skin surface, and the temperature and humidity of the needle-containing gas phase rise at the same time, and the user feels uncomfortable. In this case, when the knitted fabric is hygroscopic, it is possible to suppress a decrease in the vapor phase humidity and to suppress a decrease in discomfort. Moisture-absorbing moisture Dehumidifies from the surface of the fiber to the external environment. When heat is applied during moisture absorption, the moisture content in the gas phase rises due to the same temperature, and the relative humidity decreases, and promotes sweating from the skin -26-1277668, and as a result, the body temperature is lowered. This phenomenon continues until the bodysuit reaches the moisture absorption balance for several minutes. Finally, the moisture absorption and the moisture release amount reach equilibrium, and the heating effect is stopped. At this point, the temperature of the bodysuit drops and reaches the equilibrium temperature. When the exercise is stopped and the sweat stops, only the moisture is released and finally returned to the initial state. When the elastic yarn used in the knitted fabric of the present invention is compared with cotton fiber or wool fiber, the moisture absorption and desorption speed is slow, and the moisture absorption reaches a high level. As a result, heat generation and heat release continue in a mild state for a long period of time, particularly effectively suppressing. After the sweat stops, the temperature of the fiber is slowed down, and the cold feeling after the movement is stopped is suppressed. The inventors of the present invention have further intensively reviewed the heating effect when the concentration of the hygroscopic fine particles in the elastic yarn is changed to feel the moisture absorption in the wearing test, and as a result, it has been confirmed that the temperature increase rate must be 5 ° C /min or more. ability. Preferably, it is 7 ° C / min or more. In addition to being affected by external influences, the temperature is lower and the heating capacity is better. The knitted fabric used for the underwear of the present invention can be formed by using a typical elastic yarn of the above polyurethane elastic fiber and an inelastic fiber such as a polyester fiber, a polyamide fiber, or a cellulose fiber. In the case of a stretchable knitted fabric, in order to form a thin and aesthetically pleasing knitted fabric, it is preferred to use a single yarn of a polyester fiber or a polyamide fiber. The woven structure is a circular woven flat structure, a double-sided structure, a refined structure, a double-backed tissue or such a woven fabric, a tricot knitted fabric, a russel twill knitted fabric, and the like, and is not particularly limited. When the woven structure is a tricot knitted fabric, for example, a semi-tissue, a reverse semi-tissue, a double-breasted warp-knitted structure, a double-breasted warp satin structure, and a russell twill knitted fabric, for example, an elastic knitted fabric, a semi-elastic knitted fabric, and a satin weave. Knitted fabrics, warp knitted fabrics, etc. -27- 1277668 Elastic yarns and inelastic fibers can also be used as composite yarns of coated yarns, twisted yarns, composite yarns, and the like, and the non-elastic fibers can be interlaced with the bare yarn of polyurethane foam. The composite can also be woven with the non-elastic yarn as desired. In order to reduce the processing cost, it is better to weave the naked yarn. Further, in order to reduce the rubbery feel of the knitted fabric or the sticky feeling when moisture is absorbed, the surface layer of the knitted fabric is preferably coated with inelastic fibers. In this case, in order to sufficiently exhibit moisture absorption, heat release, antibacterial, deodorizing performance, and stretchability of the knitted fabric, the content of the elastic fibers is preferably 10% by weight or more. More preferably, it is 20 to 50% by weight. When it is more than 50% by weight, it is not only economically unsatisfactory, but also has a texture such as softness and swelling, which is not desirable. The temperature difference between the moisture absorption and heat generation characteristics of the knitted fabric of the present invention at the initial stage and after washing 10 times is less than 1 ° C, and if it is less than 1 ° C, it means having the durability of washing and maintaining the moisture absorption after 10 times of washing. Heating characteristics. The knitted fabric of the present invention is suitable for use in the underwear, and the above-mentioned elastic resin contains the above-mentioned local hygroscopic organic fine particles, so that the wearing comfort property with high expansion property or moisture absorption heat generation, moisture absorption and heat absorption, and electric performance can be formed. And a multi-functional stretch knitted fabric which has a moisturizing function by deodorizing the antibacterial effect and a moisturizing function by pH buffering performance. The invention includes the invention of a tights. Next, the pantyhose relating to the present invention will be described. The pantyhose of the present invention is characterized by having hygroscopic energy and having heat generation and warming effect when absorbing moisture. First, the temperature and humidity change when the pantyhose of the present invention is worn is about the same as that of the knitted fabric applied to the underwear. The inventors of the present invention conducted a review by changing the concentration of the high-absorbency and moisture-releasing fine particles in the elastic yarn, and feeling the warming effect of the pantyhose wearing test during moisture absorption. As a result, it is possible to increase the temperature by 7 ° C /min or more. Better ability. More preferably, it is 9 ° C / min or more. When the temperature is lower due to the influence of the external environment, the higher the heating capacity. The pantyhose of the present invention is composed of a composite yarn of an elastic yarn and a synthetic fiber yarn in terms of thinness, strength, elongation and elongation recovery, or an interwoven knitted fabric of the composite yarn and the synthetic yarn of the synthetic yarn. good. The elastic yarn is preferably a single yarn, and the synthetic yarn is preferably a single yarn. The inner surface of the pantyhose is preferably coated with a substantially synthetic single yarn. This system avoids the direct contact between the elastic yarn and the skin, and the smoothness of the skin surface is good, so it can satisfy the special characteristics of the pantyhose. When both the composite yarns are single yarns, transparency, strength, and durability are improved, so that it is preferable to synthesize a single yarn with polyester or nylon. In terms of hygroscopicity and durability, it is preferable to synthesize a single yarn to be resistant to a single yarn. The total fineness of the composite yarn is substantially 30 to 80 denier for the panty portion and 10 to 50 denier for the foot. The difference between the hygroscopic heat-generating characteristics after the initial washing and the 10 times of washing is the durability of washing and is less than 1 °C, which means that the moisturizing and heating characteristics of the body can be maintained even after 10 washings. The washing according to the present invention refers to a washing using a standard lotion of the fiber evaluation technology protocol, based on the JIS-02 1 7 - 03 method. The elastic yarn containing the highly absorbent organic fine particles is preferably contained in an amount of 20% by weight or more, and if it is less than the above range, the moisture absorption and desorption characteristics are insufficient and there is an odor, which is not desirable. Moreover, the tight sense of tight stockings is not enough. The better is 25 to 40%. In the case of pantyhose, the trousers and the feet are generally composed of different yarns. When the two are formed of the same yarn, there is no problem. When only one of the elastic yarns containing the hygroscopic organic fine particles is used, it means a composition ratio of the elastic yarn containing the hygroscopic organic fine particles in only the knitted fabric. -29- 1277668 The knitted fabric in which the moisture absorption and the heat absorption and the heat absorption are repeated in the environment are designed to be used in the pants portion and the foot portion, respectively, and the pantyhose is designed depending on the season and the environment. For example, in the summer pantyhose, it is possible to obtain a cool pantyhose with a dry feeling by using an elastic yarn containing only heat-absorbing/absorbent organic fine particles in the foot portion; in winter, it is preferably used for both the pants portion and the foot portion. The pantyhose of the present invention is preferably characterized in that it has at least one selected from the group consisting of ammonium, acetic acid and isovaleric acid having a deodorization ratio of 70% or more. These components are used as a odor component of sweat odor, and have the ability to eliminate the odor of these components, especially for any of the above three components. At the time, it is easy to have the odor performance after eliminating sweating, and the performance is aimed at 70% or more. Therefore, if it is less than 70%, the performance is insufficient and it cannot be said that it has deodorizing performance. Preferably, the deodorizing performance is 85% or more, and more preferably 90% or more. The pantyhose of the present invention preferably has a deodorization rate of 70% or more selected from the group consisting of ammonium, acetic acid and isovaleric acid before washing and after washing. Since the commercially available stockings have a deodorizing component and are almost completely processed after forming a product, the deodorizing performance is deteriorated after washing, for example, due to poor durability of the washing, for example, in the initial stage, the deodorizing performance is deteriorated. The preferred elastic yarn used in the stockings of the present invention is integrated with the fibers on the surface and inside of the fiber, so even if it is washed, its performance will not deteriorate at all. . The deodorization rate after washing is more preferably 80% or more, and the best is 85% or more. The stockings of the present invention preferably have a friction band voltage of 2500 V or less. If the friction band voltage is greater than 2500V, it tends to stick to it when wearing a skirt, especially in low-humidity winters, which tends to be uncomfortable when worn. The preferred range is 2000 V or less, and more preferably 1 500 V or less. -30- 1277668 The stocking of the present invention has a half-life of a voltage of 50 seconds or less. Similarly to the friction band voltage, the half-life of the voltage band is a parameter for evaluating the entanglement easiness. When the number 値 is 50 seconds or less, for example, the left and right stockings and the skirt are externally rubbed to cause static electricity, and the voltage is applied. The speed is reduced, so it is not easy to have discomfort. On the other hand, if it is more than 50 seconds, it is easy to feel uncomfortable when wearing it in the winter season of low humidity. Preferably, it is 30 seconds or less, and more preferably 15 seconds or less. Next, the fabric of the present invention will be described.
