200404109 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 日寸會有悶熱感等之不快感，以及汗溫下降後會產生冷感等 問適’於巾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、 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、v ο 1. 4 7， No. 10,491記載的各種親水加工。 提高聚胺甲酸酯系彈性之吸水性技術，於日本專利公 200404109 開、特開平1 1 - 8 1 046號公報中揭示。揭示藉由具有高吸水 性與高生物體親和性優異的物理強度、加工性良好的水不 溶性、非離子性吸水性聚胺甲酸酯紗及熔融紡紗之製法。 然而，由於水吸收率爲200%以上、且纖維構成高分子本身 具有高吸水性能，該纖維於洗濯時、或汗吸水時纖維表面· 膨脹、呈現微溫感，故使用作爲衣料用途時會有問題產生。· 於日本專利公開、特開200卜98423號公報中，揭示在基 體聚合物之聚醇成份中使用親水性聚醇之聚烷二酸聚醇， 以提高聚胺甲酸酯系彈性纖維之吸濕性技術。藉此可以解 決特開平1 1 - 8 1 0 4 6號公報之問題，揭示使用於衣料用途時 在不會影響質感之水準下可降低膨脹之影響，惟會有下述 問題。 提高聚胺甲酸酯系纖維之透濕性技術中混合高吸水性聚 合物的方法中，例如有丙烯酸系聚合物、聚乙烯系聚合物、 聚醯胺系聚合物、高吸水性聚胺甲酸酯系聚合物等，惟由 於此等高吸水性聚合物局部存在，會有降低物性或揖及結 紗安定性之問題。另外，由於一般該高吸水性聚合物不會 交聯，與因吸水產生膨脹、導入上述親水性聚醇相同地， 聚胺甲酸系彈性纖維會導致膨脹、被覆或編成工程中伴隨 殘渣附著於接紗導線等，而有斷紗或品質不佳的後加工問 題。 此外，近年來對聚胺甲酸酯系彈性纖維之耐熱性要求提 高，特別是自古以來企求可與必須高溫高壓染料的聚酯纖 維父織的聚胺甲酸酯異彈性纖維。對該要求而言，例如曰 本專利公開、特開平5 - 1 8 65 5 7號公報、特開平夂1〇2〇35號 200404109 公報中揭示，使用聚胺甲酸酯溶液使聚胺甲酸酯聚合物於 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 - 2 2 8 1 5 5號公報及特開平9-25627 8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 200404109 汗後冷感之效果者’例如日本專利公開、特開平9-158〇4〇 號公報或特開2 0 0 0 - 3 0 3 3 5 3喊公報中揭示，丙烯酸罕吸濕發 熱纖維。然而，所得纖維主要爲短纖維，由於機械性能稍 微不佳，故不易製得細紗或薄質的織物，且可藉由與胺甲 酸酯系彈性紗複合形成彈性紗，美觀性無法令人滿足。 Λ 而且，例如日本專利公開、特開2002-38375號公報中，* 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 遍以絲德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 支擦型絲襪，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 200404109 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、美觀性之婦人絲襪。 有鑑於此等狀況，例如日本專利公開、特開2 〇 〇 丨3丨8 〇 2 號公報中’提案在後加工中使吸濕發熱樹脂粒子以黏合樹 脂固定於耐龍與聚胺甲酸酯彈性紗之複合紗構成的絲襪方 法’惟吸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。 換曰之’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，穿著妨礙運動性之厚質 衣料時’會多消耗體力。衣服內雖可放置懷爐等之熱源， -10- 200404109 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、特開平9 - 5 9 8 7 2號公報記載的父聯丙嫌酸系繊維。 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 溫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趣合作 爲工作服等之伸縮性，且不具容易活動性。 【發明內容】 200404109 本發明之第i課題係提供一種適合保溫性高、具有舒適

°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 0°C以下爲宜。 φ 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- 200404109 本發明之彈性纖維係以2(TC X 65%RH與 20t 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(l〇〇%伸長下、乾熱19(TC處理1· 分鐘後之乾熱定形率）以6 0 %以上較佳。若該數値小於6 0 % 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130°C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7 5 %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， 200404109 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、多孔質二氧化政微粒 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2 0 μ m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，反而會使聚胺甲酸醋系彈个生 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、γ 之任何形狀。 高吸放濕性微粒子對聚胺甲酸酯系彈性纖維_ w 0.2重量％以上較佳。更佳者爲0 · 5重量％以上。^ 重量％時，缺乏吸濕性，故不爲企求。惟含量若過A 紡紗階段之曳紗性降低、且斷紗情形多，故以5〇 g 下較佳、更佳者爲4 8重量％以下。 、發熱 添加混 彈性纖 乾式紡‘ 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 -19- 200404109 本發明所使用的高吸放濕性微粒子之膨脹度以2〇〇%以 下較佳、更佳者爲1 0 0 %以下。若膨脹度大於2 〇 〇 %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。局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，2 0 °C X 6 5 % RH之高吸放濕 性有機微粒子的水分率爲3 0 %以上較佳。更佳者爲3 5 %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 °C X 65 % RH之 水分率爲1 5 %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 X65 % 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20μηι以下、 較佳者爲ΙΟμίΉ以下、更佳者爲5μιη以下、最佳者爲2μιη 以下，其含量對纖維而言以〇 · 2〜5 0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- 200404109 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LpNa、K等之鹼金屬、Mg、Ca、Ba等之鹼土 類金屬、Cu、Ag、Mri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 由肼、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 鲁 有l.〇mm〇l/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〜丨5 · 〇之肼處理導入交聯架 -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mm〇l/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羧基，以具有2.0inm〇1/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〜 10.0mmol更佳。高吸放濕性有機微粒子之製法例如可藉由 曰本專利公開、特開平8 -225 6 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（mmol/g)與纖維中微粒子濃度（重量％) 之積通常爲40〜80、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- 200404109 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5 0 %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g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

丨生紗爲被覆彈性纖維之狀態時，可提供長、高保溫效果及 舒適性。 另外’本發明之彈性纖維亦可使用於褲襪。該用途重視 穿者時之美觀性、且要求薄布帛，故特別可發揮本發.明之 效果。 本發明彈性纖維之交織原料可以爲熱塑性合成纖維、天 -23- 200404109 然合成纖維、再生纖維中任何一種，爲熱塑性合成纖維時 可採用聚醋纖維、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 1 00 %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2 0重量％以上較佳’就保持穿著時內襯佳而 言以5 0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- 200404109 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 Q °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32 °C、70%RH之氣氛中以熱度表使針織物表面連續5分鐘以 測疋表面溫度’測定最大的溫度，與3 2 °C之差値作爲上升 修 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6 0〜1 0 0 %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60〜95%。 φ 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- 200404109 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 則者時，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- 200404109 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 f友回俱至初期狀態。 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 高爲宜。 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、雙梳櫛經锻組 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。 200404109 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酯 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，以裸紗交織較佳。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 〇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 脂中由於含有上述高吸濕性有機微粒子，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 月巨、以及藉由消臭ί几囷效果之衛生功能、藉由p Η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 200404109 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 〇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1 0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；r IS - 0 2 1 7 - 1 0 3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- 200404109 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， 該性目纟以7 0 %以上爲目標。因此，若小於7 〇 %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8 5 %以 — 上、更佳者爲9 0 %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7 0 %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 馨 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，。洗灌後消臭率之更佳範圍爲8 〇 %以 上，最佳者爲8 5 %以上。 本發明之絲襪以摩擦帶電壓爲2 5 〇 〇 V以下較佳。若摩擦 帶電壓大於25 00V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2〇〇〇v 以下、更佳者爲1500V以下。 -30- 200404109 本發明之絲假以w電壓之半哀期爲5 0秒以下較佳。湿摩 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 參數，該數値爲50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 t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2〇%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6〇%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、$父佳者爲2 °c以上。吸濕時織物表面上升溫度 200404109 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35%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 紗之纖度通常爲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 L 1 0 1 3 ( 2 0 0 0)(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- 200404109 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1〇〜1〇〇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 200T/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 φ 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 3 0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- 200404109 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- 200404109

relates to an application of elastic fibers and fabrics having moisture absorption and heat generating properties, and a method for producing knitted fabrics. [Prior art] In the past, fabrics that value moisture retention tend to be thick or heavy. When wearing these fabrics, there are problems that they are heavy, difficult to move, and detrimental to fashion. In addition, due to insufficient moisture release after sweating, there will be unpleasant feelings such as sweltering feeling when sweating on commuting trams, etc., and cold feeling after sweat temperature is reduced. Excellent fabric. Especially in a stretchable fabric using elastic fibers, the above-mentioned problems are particularly noticeable when the fabric is in contact with the skin to ensure thermal insulation as a thick fabric. In addition, for applications that are intimately fitted and aesthetically pleasing (e.g., stockings, bodysuits), excessive thickness will reduce the aesthetics at the time of wearing and cause many problems. In order to ensure the thermal insulation of such thin fabrics, various reviews are conducted. Most of the people who choose to change the knitting structure or the general-purpose yarn can not be determined. The effect is not sufficient. At present, it is still not possible to produce heat insulation, lightweight, comfort, Beautiful fabric. In addition, polyester fibers, nylon fibers, and polyurethane elastic fibers are different from natural fibers such as cotton, wool, and silk. They generally lack hygroscopicity due to their low content of hydrophilic functional groups. Therefore, the hydrophilization technology of synthetic fibers has been studied for many years. For example, various hydrophilic processes described in the dyeing industry and v ο 1. 4 7, No. 10,491 have been proposed. A water-absorbent technology for improving polyurethane-based elasticity is disclosed in Japanese Patent Publication No. 200404109, Japanese Unexamined Patent Publication No. 1 1-8 1 046. The method of producing a water-insoluble, non-ionic water-absorbent polyurethane yarn and a melt-spun yarn having excellent physical strength, excellent processability, and high water absorption and high bioaffinity is disclosed. However, since the water absorption rate is 200% or more, and the fiber-forming polymer itself has high water absorption performance, the fiber surface swells and shows a slight warmth when the fiber is washed or sweat absorbs water. Therefore, it is used when it is used as clothing. Problems arise. · In Japanese Patent Laid-Open Publication No. 200-98423, it is disclosed that a polyalkylene polyalcohol using a hydrophilic polyalcohol in the polyalcohol component of the base polymer is used to improve the absorption of polyurethane-based elastic fibers. Wet technology. This can solve the problems of JP-A No. 1 1-8 1 0 4 6 and reveal that the effect of swelling can be reduced without affecting the texture when used in clothing applications, but there are the following problems. In the method for improving the moisture permeability of polyurethane-based fibers, a method of mixing superabsorbent polymers includes, for example, acrylic polymers, polyethylene polymers, polyamide polymers, and superabsorbent polyurethanes. Ester-based polymers, etc. However, due to the local presence of these highly water-absorptive polymers, there is a problem that physical properties are reduced, and the stability of yarn knotting is reduced. In addition, since the superabsorbent polymer is generally not crosslinked, similar to the introduction of the above-mentioned hydrophilic polyalcohol due to swelling due to water absorption, the polyurethane elastic fiber causes swelling, coating, or weaving process with residues attached to the connection. Yarn leads, etc., and there are problems with yarn breakage or poor quality post-processing. In addition, in recent years, heat resistance requirements of polyurethane-based elastic fibers have been increased, and especially since ancient times, polyurethane heteroelastic fibers that have been woven with polyester fibers that require high-temperature and high-pressure dyes have been sought. In response to this requirement, for example, the present patent publication, Japanese Patent Application Laid-Open No. 5-1 65 65 5 and Japanese Patent Application Laid-Open No. 102035 200404109 disclose that a polyurethane solution is used to make polyurethane. The technology of forming an ester polymer into a polymer by heat treatment is known to improve the heat resistance of polyurethane-based elastic fibers. However, the polyurethane-based elastic fibers using these technologies can improve the heat resistance to heat treatment in post-processing, but it is difficult to control the production volume depending on the purpose, and the processability is poor and the post-processing passability is good. problem. In addition, when the above-mentioned hydrophilic group is introduced into the polyol component, there is a problem that the heat resistance of the heat treatment during the post-processing is lowered, and it is difficult to interweave with the polyester fibers that must be dyed at high temperature and pressure. Next, the conventional techniques related to fabrics are explained. Polyester fibers, polyamide fibers, cellulose fibers, and other non-stretchable fabrics made of polyurethane elastic yarns have excellent elasticity and can be used in tights or pantyhose, bras, and rhythm Basic clothes such as uniforms, or other stretchable straps such as bellybands, sportswear, ski pants, stretch thick cotton pants and other outerwear, stretchable underwear, base fabrics of stretchable tape, supportive medical uses, or stretchable shoes Base cloth and many other uses. In particular, for women's underwear, due to appropriate stretchability and thinness, composite knitting of elastic yarns such as polyurethane and nylon is the mainstream. However, 'synthetic fiber has poor moisture permeability, so there is a problem of sweltering feeling. In addition to the above-mentioned method using hygroscopic polyurethane, the method for solving the sweltering feeling is, for example, Japanese Patent Laid-Open No. 9-2 2 8 Japanese Patent Publication No. 1-5 and Japanese Patent Application Laid-Open No. 9-25627 No. 8 disclose hygroscopic dragon yarns having improved hygroscopic properties using dragon fiber. The comfort required for intimate clothing is evaluated by the effect of humidity control and moisturizing performance, and the effect of suppressing self-heating at the beginning of wearing, and the effect of warming and the cold feeling after sweating 200404109. 158040 or JP 2 0 0-3 0 3 3 5 3 disclosed that acrylic acid rarely absorbs heat-generating fibers. However, the obtained fibers are mainly short fibers. Due to the slightly poor mechanical properties, it is not easy to produce spun yarns or thin fabrics, and elastic yarns can be formed by compounding them with urethane-based elastic yarns. The aesthetics are not satisfactory. . Λ For example, in Japanese Patent Laid-Open Publication No. 2002-38375, * it is proposed to fix acrylic moisture-absorbing and exothermic resin particles to a nylon or polyester fabric by resin adhesion or graft polymerization in post-processing. The method on the surface 'except that there are hygroscopic particles in the surface layer system, and there is a problem of stickiness or lack of washing durability when the moisture is absorbed, or the texture is hardened. Next, the conventional techniques related to stockings will be described. Ever since the advent of Nylon yarns, Silk has been widely used as clothing to improve the beauty of women's feet, and the emergence of pantyhose has extended its use. In addition, with the advancement of preferences, we are seeking to differentiate products that are more transparent and more flexible. One of them is a stocking-type pantyhose that seeks for a more tight feel. Stockings that use polyurethane elastic fibers and topspun yarns are still the mainstream. The stockings of synthetic single yarns with high strength, thinness, and excellent wear durability are precious, but they have the disadvantage of lack of heat retention during severe cold. In addition, since hygroscopicity is low, it is desired to improve the sweltering condition when sweating. In addition, the sweltering situation may have a strange smell in the shoes, which is one of the troubles of women. There are many fibers with excellent hygroscopicity in synthetic fibers. Generally, they are low in strength, thin, and cannot be used for stockings that demand durability. The single yarn used in stockings is resistant to dragons or polyesters, especially resistant to dragons. The synthetic fiber has a high moisture content and high strength, so it is resistant to single yarns. However, there are many problems in severe cold or extremely hot weather. The extreme cold needs to be thick, so many young women are dissatisfied with the appearance of 200404109. Conversely, when you are not wearing stockings barefoot in the heat, you often wear it dissatisfied when you pay attention to the appearance and tightness. In recent years, the tight-knit stockings known as support type have higher requirements. Elastic yarns such as urethane and nylon-resistant composite yarns are the mainstream, but the above-mentioned nylon-resistant fibers are used to solve the sultry feeling ~ The hygroscopic properties are improved by hygroscopic resistance, dragon yarn, or the use of the above hygroscopic polyurethane. Proposals have been made to improve hygroscopicity and comfort, and stockings rich in comfort. Until now, hygroscopic or antibacterial, The deodorizing effect is still insufficient. The effect of moisture absorption and heating is known in the conventional cotton or wool fiber system, but the same type as the above is still not suitable for women's stockings that require thinness and beauty. In view of these circumstances, for example, in Japanese Patent Laid-Open Publication No. 2000 丨 3 丨 802, it is proposed to fix the hygroscopic heat-generating resin particles to the nylon and polyurethane in a post-processing with an adhesive resin. The method of stockings made of composite yarn of elastic yarn 'except that the absorption particles exist in the surface-resistant dragon yarn, and there is a problem of stickiness or insufficient washing durability during moisture absorption, and the texture may be hardened. Secondly, it will mainly explain the conventional technology about long-fiber fabrics. In other words, “exercise usually warms muscles or joints before starting exercise” to prevent injuries, improve exercise ability, and warm up. Warming up is especially important in outdoor competitions in the cold. At this time, the warm clothes worn by the athletes need to warm up for a long time because the raw materials of the clothing have a thermal insulation effect, but they do not have a heating effect. In order to avoid this situation, when the body is effectively warmed up in a short period of time, it will consume a lot of energy when wearing thick clothing that hinders exercise. Although a heat source such as a stove can be placed in the clothes, -10- 200404109, only the local heating can be performed under this heating, which restricts its effect and hinders movement. In addition, golf or skiing for long periods of time outside the house in winter seeks clothing that has a warming effect. In addition, in addition to sportswear, general clothing or underwear for winter is also expected to have a heating effect. Here, the fiber having a hygroscopicity and a temperature-controlling effect is, for example, a paclitaxel-based fluorenic acid disclosed in Japanese Patent Laid-Open, Japanese Patent Application Laid-Open No. 9-5 9 8 7. However, the crosslinked acrylic fiber not only does not have stretchability suitable for sportswear ', and it does not consider easy mobility. In addition, it is mainly related to short-fiber fabrics, that is, work clothes worn in the workplace. Generally, the fabrics seek to protect the body in addition to thermal insulation or decorative effects. For example, work clothes for outdoor work are also required to have functions such as preventing injuries, blocking UV rays, and protecting the skin. In addition, medical uniforms or laboratory uniforms as required are required to have an effect of preventing body contamination due to bacteria and the like. In addition, in the work clothes, companies are required to properly maintain the temperature and humidity in the clothes, and can be easily operated, especially for winter work clothes outside the house, in order to have the effect of keeping warm and releasing sweat out of the clothes. When it is necessary to have the function of moisture absorption or water absorption, cotton 帛 is mainly used, but because the cotton fiber is not quick-drying, it will be sticky or feel cold at work. Wool cloth has excellent thermal insulation effect and the effect of exuding moisture from clothes to the outside, but it has poor mechanical durability as work clothes. Here, the above-mentioned crosslinked acrylic fiber system of a fibrous material having a hygroscopicity and a temperature-controlling effect is known. However, the cross-linked acrylic fiber does not have the flexibility to cooperate with work clothes and the like, and is not easily movable. [Summary of the Invention] 200404109 The i-th problem of the present invention is to provide an elastic fiber suitable for a stretchable fabric with high heat insulation, comfort and aesthetics, and to provide a post-processing passability, excellent heat resistance, And it can quickly remove the water vapor generated by sweating during exercise, and the elastic fibers of the stretchable clothing without sweltering feeling. '' The second problem of the present invention is to provide a fabric with high moisture absorption and heat generation, excellent thermal insulation properties due to the hair, and excellent stretchability, and in particular, has excellent heating effect due to moisture absorption, and sports such as sports Fabric with excellent warm-up effect. In addition, there is provided a fabric having both wearing comfort, selectivity, hygiene, durability, and softness to the skin in underwear applications and the like, and underwear using the fabric. A third object of the present invention is to provide stockings with hygroscopicity, a warming effect during moisture absorption, and a comfortable state, and stockings having both antibacterial, deodorizing effects, and excellent washing durability. The fourth subject of the present invention is a clothing having a warming effect and easy movement, and a fabric suitable for the same. 1.

First, the invention related to elastic fibers will be described. ’The elastic fiber of the present invention preferably has a maximum temperature rise of 2 t-or more when absorbing moisture and / or water. More preferably, it is above 3 ° C. Elastic fibers with this characteristic are thin and can give fabrics high moisture retention. However, if the maximum temperature increase during moisture absorption and / or water absorption is too high, in addition to the increase in yarn breakage during yarn production, it may cause unnecessary excessive temperature rise in actual knitting, so it is not required. Usually elastic fibers The maximum temperature is preferably below 10 ° C. φ In addition, the elastic fiber of the present invention has the above-mentioned exothermic property, and the moisture absorption rate of 20 ° C X 65% RH is 0. Above 5%, the moisture absorption rate at 20 ° C X 95% RH is 1. More than 5% is preferred. The better is 20 ° C X 65% RH with a hygroscopicity of 1. 0 ~ 5. 0%, 20 ° C X95% RH hygroscopicity is 2 · 0 ~ 15. 0%. The elastic fibers having the above characteristics are effective in absorbing sweat in addition to making a certain heat-retaining fabric as thin as possible, so even if the body temperature is sweating, there is still no discomfort. It is warm and does not have High comfort for sultry feeling. In addition, it can relieve the cold feeling when sweat cools down after sweating. -17- 200404109 The elastic fiber of the present invention has a moisture absorption difference of 2 (TC X 65% RH and 20t X 95% RH as 1. Above 0% is better, and even better is 2. 0% or more. The number indicates the ability to absorb sweat. The larger the number, the higher the capacity. 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-based elastic fiber of the present invention was determined by the following measurement method, PSD (100% elongation, dry heat 19 (dry heat after 1 minute of TC treatment) The setting rate) is preferably 60% or more. If the number is less than 60%, the texture dimension stability in the pre-fixation project is not good, so it is not a goal. Then, the polyurethane of the present invention is Moist heat fixation of elastic fibers is determined by the following measurement method, PSW (within 60 minutes at 100% elongation, moist heat, after heating from 40 ° C to 130 ° C, and continuous heat treatment at 60 minutes under moist heat at 130 ° C.) The setting rate) is preferably 75% or less. This number indicates the heat resistance in the dyeing process. 'The larger the number, the better the heat resistance. In short, if the PSW is greater than 75%, it is difficult to meet the high temperature and pressure requirements. Dyed polyester fibers are interwoven, and the elastic response rate will be reduced, so it is not desirable. Since elastic fibers are generally not exposed on the surface of the fabric and exist inside the fabric for clothing, the elastic fibers heat from the interior of the fabric when it is heated , Can achieve the same effect that the heating body is covered with a thermal insulation material, can have Insulation, heat storage, and high comfort. When the non-elastic fibers exposed on the surface of the fabric are exothermic, the exposed part on the opposite side of the human body is not quickly cooled, and when the part on the human side is heated, the comfort is reduced. In addition, the method of using an adhesive to attach a heating agent or the like to the surface of the cloth or containing fibers on the exposed surface by using an adhesive when absorbing moisture is not only easy to damage the texture, but also durability during washing. Insufficient, so it is not a goal. In general use, elastic fibers rarely expose the surface of the fabric, 200404109 has the advantage of not damaging the texture. It is better to contain moisture absorbing agents inside the elastic fibers. The method of wetness is to make highly absorbent and moisture-absorbing fine particles to the raw material polymer of the elastic fiber, and it is very effective for spinning. Typical examples are polyurethane elastic fibers. Spinning can be performed by yarn and wet spinning. Yarn or melt-spinning method. Organic particles and / or inorganic particles can be used for the high absorption and release particles, such as polyacrylic particles and polyethylene polymer particles. Polyurethane-based polymers, micro-urethane-based polymer particles, porous silica particles, and water-based silica particles. The particle size is 20 μιη to prevent deterioration of physical properties and good spinning and processing properties. Below, the better; | Below, the better is 5 μm or less. The best is 2 μm or less. When this is the above purpose, it is necessary to make the high moisture absorption and desorption during the spinning process slightly dispersed in the fiber. If When the particle diameter is larger than 20 μm, it will be separated after adding and mixing, and there will be halo on the fiber surface, which may cause yarn breakage due to spinning cuts or post-residue adhesion. However, if the average particle diameter is too small, it will easily cause aggregation. In some cases, the dispersion of polyurethane bombs is not good, so it is better to be more than 0.1 μm. Moreover, there is no particular limitation on the particle shape, and it can be spherical, slightly flat, or γ. Any shape. Polyurethane-based elastic fibers with high moisture absorption and release particles _ w 0. It is preferably 2% by weight or more. More preferred is 0.5% by weight or more. ^ At% by weight, it lacks hygroscopicity, so it is not desirable. However, if the content exceeds the A spinning stage, the slackness is reduced, and the yarn breakage is often the case. Therefore, it is better at 50 g, and the more preferable is 48% by weight or less. , Heat added mixed elastic fiber, dry spinning, ‘wet micro · polymer particles, particles, and parent workability I 1 0 μηη is to achieve particle size and particle partial processing, the shape and shape of the particle fiber inner content is 0,0. At 2 o'clock, the amount of swelling is -19-200404109. The degree of swelling of the highly hygroscopic and microscopic particles used in the present invention is preferably 200% or less, and more preferably 100% or less. If the degree of swelling is more than 2000%, the polyurethane elastic fiber itself swells due to moisture, which may cause yarn breakage and poor quality due to residue adhesion during surface coating or knitting. The smaller the swelling degree of the local absorption and release moisture particles, the better. In the polyurethane-based elastic fiber of the present invention, expansion due to moisture absorption not only causes high absorption and release ~ wet organic fine particles become smaller, but the polyurethane-based polymer forming the fiber is hardly affected by absorption. Swelling caused by wetness rarely causes problems with yarn breakage due to residues adhering to the splicing wire, etc., or poor quality post-processing. The highly hygroscopic and fine particles used in the present invention have a high moisture content of 20 ° CX 65% RH. The highly hygroscopic and fine organic particles of non-green polymer are preferred. The better chemical composition is as follows, 2 The moisture content of the highly absorbent and desorbable organic fine particles of 0 ° CX 65% RH is preferably 30% or more. The better is more than 35%, and the best is more than 40%. In the past, among the fine particles having hygroscopicity, wool powder or chitin powder had the highest hygroscopicity, and the moisture content of 20 ° C X 65% RH was as high as 15% or more. In addition, polysaccharides such as starch, cellulose, silk, and colloids, or protein-based microparticles are 8 to 12% smaller than the aforementioned wool powder or chitin powder. The moisture content of other urea resin or melamine resin powder at 20 ° C X65% RH is more than 30%, so it is not desired, and to prevent the physical properties of elastic fibers from decreasing, the spinning operation and post-processing passability are good. At the time, the particle diameter of the highly hygroscopic fine particles is 20 μηι or less, preferably 10 μίΉ or less, more preferably 5 μιη or less, and most preferably 2 μιη or less, and the content thereof is 0.2 to 50 weight for the fiber. % Is better. When the content is lower than this range, sufficient effects cannot be obtained, and when the content is higher, the yarn breakage is induced when the elastic fiber is produced. -20- 200404109 When the elastic fiber of the present invention contains highly hygroscopic and desorbable organic microparticles made of a polymer of a non-green system, the hydrophilic groups of the highly hygroscopic and desorbable organic microparticles have a salt type carboxyl group and a salt type sulfonic acid. Acid group, salt-type phosphate group, salt-type phosphate group, etc., salts include alkali metals such as LpNa, K, alkaline earth metals such as Mg, Ca, Ba, other metals such as Cu, Ag, Mri, ammonium, amine, etc. Salts such as organic cations may contain an acidic group in addition to the salt type. A highly hygroscopic organic micro-particle system is introduced into a cross-linked structure by hydrazine, divinylbenzene or triallyl isocyanate treatment in an acrylonitrile polymer containing 50% by weight or more of acrylonitrile, and the remaining nitrile groups are made. By hydrolyzing chemical transformation into salt carboxyl groups to have a l. 〇mm〇l / g salt carboxyl group is more preferred. Although there is no particular limitation, more specifically, for example, (a) is treated with hydrazine in an acrylonitrile-based polymer containing 85% by weight or more of acrylonitrile and the nitrogen content is increased by 1 · 〇 ~ 丨 5 · 〇 Introduce the cross-linking structure-structure 'and make the remaining nitrile group chemically transformed into a salt carboxyl group by hydrolysis to have l. 〇mm〇l / g salt-based carboxyl group of acrylic metal-converting particles, (b) A crosslinked structure is introduced by divinylbenzene or triallyl isocyanate treatment, and is contained in an acrylonitrile polymer containing 50% by weight or more The residual nitrile group is chemically transformed into a salt carboxyl group by hydrolysis to have 2. 0inm〇1 / g salt type · Acrylic metal conversion particles of carboxyl group, etc. The amount of salt carboxyl group is 4. 0 ~ 10. 0mmol is more preferred. The method for producing highly hygroscopic organic fine particles can be produced, for example, by the method described in Japanese Patent Application Laid-Open No. 8-225 610. The moisture absorption and heating effect of the elastic fiber of the present invention is mainly derived from the salt-type carboxyl group, so the product of the concentration of the salt-type carboxyl group (mmol / g) and the concentration of the fine particles in the fiber (wt%) is usually 40 to 80, preferably 45. ~ 75, it is better to fix the fine particle concentration in the fiber. If the content of fine particles in the elastic fiber is in the above range, the body can feel a sufficient warmth, and the problem of difficult spinning due to yarn breakage will not occur -21- 200404109. These metal-converting particles are crosslinked acrylic polymer microparticles, and the monomers used in the acrylonitrile polymer of the starting microparticles for acrylonitrile halide are vinyl halide, vinylidene halide, acrylate, methacrylate, P-styrenesulfonic acid-containing monomers and their salts, acrylic acid-containing monomers and their salts, acrylamide, styrene, vinyl acetate, and the like. The elastic fiber containing the highly hygroscopic organic fine particles has both good heat-generating and hygroscopic properties. When the highly hygroscopic organic fine particles are added to polyurethane elastic fibers, they have significantly higher heat generation and hygroscopicity than those of ester or non-elastic non-elastic fibers. In addition, polyurethane elasticity Physical properties such as the strength and elongation of the fiber are extremely reduced. Although the reason is unknown, it is presumed that it is easy to halo on the fiber surface. In addition, the highly hygroscopic organic fine particles have excellent antibacterial properties and deodorizing properties, and particularly have an additive value of elastic fibers used in stockings, tights, and the like. The elastic fiber of the present invention refers to a fiber having a rubber elastic behavior from a social point of view, for example, it can be stretched at least 50% or more, more preferably it can be stretched 100% or more 'and has a recovery rate of 20% or more. The recovery rate here refers to the length of the entire stretch and g is reduced by the recovery. Typical examples are polyurethane elastic fibers having particularly excellent stretchability. The polyurethane polymer used in the elastic fiber of the present invention may be an intermediate polymer having isocyanate groups at both ends formed of a polyalcohol and an excessive diisocyanate compound, and dissolved in N, N, -dimethyl It is obtained by reacting a diamine compound in an inert organic solvent such as vinylideneamine and dimethylmethylenesulfonate. The above-mentioned polyhydric alcohol is not particularly limited, such as a polymer diol. Specifically, for example, one or two or more kinds of polyether glycols selected from the group consisting of polyethylene oxide, polypropylene oxide, polytetramethylene glycol, 200404109 polypentaerythritol, and polyoxypropane tetramethylene glycol. Dibasic acids such as adipic acid, sebacic acid, maleic acid, itaconic acid, azelaic acid, and fumaric acid, and one or two or more kinds of ethylene glycol, 1, 2-propanediol, 1, 3-propane Polyester diols obtained from monohydric alcohols, 2,2- = methyl d,% propylene glycol, 丨, 4-butanediol, 2,3-butanediol, hexamethylene glycol, and glycols, poly-ε_ Caprolactone and polyvalerolactone, such as polylactone difluorene f, polyester amidamine glycol, polyetherester glycol, polycarbonate glycol, etc. The monoisocyanate compound is not particularly limited as long as it is an aliphatic, cycloaliphatic, or aromatic diisocyanate Sh η product. For example, methyl-bis (phenylene isocyanate), methyl-bis (3-methylphenyl isocyanate), 4-methyl-tolyl diisocyanate, 2,6-methyl-tolyl diisocyanate, m- and para- P-phenylene diisocyanate, m- and p-xylyl diisocyanate, methylene_bis (4-cyclohexyl isocyanate), 丨, 3_, and 丨, carbocyclohexyl diisocyanate, trimethylene diisocyanate, Tetramethylidene diisocyanate, hexamethylidene diisocyanate, isophorone diisocyanate, etc. Chain elongation; one of 4fe: compounds are not particularly limited, such as ethylenediamine, propanylamine, dimethylmonoamine, hexamethyldiamine, 丨, 2-cyclohexanediamine, 丨, cyclohexanediamine , 1, cyclohexanediamine and hydrazine. As the elastic fiber of the present invention, a surface layer yarn and a false twisted yarn can be used. When the above-mentioned composite elastic yarn is covered with elastic fibers, it can provide long and high thermal insulation effect and comfort. In addition, the elastic fiber of the present invention can also be used in pantyhose. This application pays attention to the aesthetics of the wearer and requires thin fabrics, so it can make full use of the hair. Ming effect. The interwoven raw material of the elastic fiber of the present invention may be any of thermoplastic synthetic fiber, Tian-23-200404109, and synthetic fiber, and recycled fiber. When the thermoplastic synthetic fiber is used, polyester fiber and polyamide fiber may be used. When the natural fiber is used, it may be used. Cotton and wool 'recycled fibers can be used with high wet modulus viscose fibers. The interweaving of the target material with the elastic fiber of the present invention is not limited to these. For example, when the elastic fiber is generally covered with the target material during the interlacing, a polyester fiber or the like is coated on the elastic fiber and used for warp and / or weft. In addition, when interwoven with the target material, it can be directly pulled and knitted with the target material, and woven with the covering yarn at the same time. As for the dyeing processing of the obtained stretchable knitted fabric, it is possible to use a general processing process of pre-fixing after loosening and scouring, dyeing, drying, texture treatment, and fixing. Next, the knitted fabric of the present invention will be described. The knitted fabric of the present invention is a highly stretchable knitted fabric composed of the above-mentioned elastic yarn and non-elastic fibers, but the non-elastic fibers of the present invention are synthesized from natural fibers such as wool, cotton, and silk, or nylon, polyester, etc. Single yarn, fibers with a break elongation of less than 100%. The non-elastic yarn is substantially free of moisture-absorbing and exothermic organic fine particles, and it is preferable that the surface of the knitted fabric is covered with non-elastic fibers. The term "hygroscopically-free organic fine particles" as used herein refers to the amount of particles that are not included in the moisture absorption of the knitted fabric, even if it contains a small amount. The mixed rate 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 heating effect, and is preferably 50% by weight or less in terms of maintaining good lining when worn. Compared with cotton fibers or wool fibers, the elastic yarn of the present invention has a slow absorption and release speed and reaches a high level of moisture absorption. As a result, it generates heat, and the heat release continues for a long time in a mild state. Especially, the fiber temperature decreases after the sweating stops. Slow, with a sense of coldness after stopping exercise. In addition, -24-200404109 salt carboxyl group has various effects such as deodorization, bacteriostatic, antibacterial, pH buffering, electricity production, etc. in addition to its hygroscopic and heat-generating effects, and it is a product with ideal properties as a warmer. In addition, it is suitable for use as a swimwear because bacteria do not multiply even in the shade. When the knitted fabric of the present invention absorbs moisture, the surface temperature of the knitted fabric rises by more than 3 ° c. The heat generation during moisture absorption is to make the knitted fabric at 7 Q ° C; after drying for 2 hours, adjust the temperature in a desiccator with silicone for more than 8 hours, and then adjust the temperature to 32 ° C and 70% RH. Using a heat meter, the surface of the knitted fabric is continuously measured for 5 minutes to measure the maximum surface temperature, and the difference between the maximum temperature and 3 2 ° C is used as the rising repair temperature. When the temperature is less than 3 C, the effect of somatosensory is lacking, and the higher the rising temperature, the better, about 10 ° C. The elongation characteristic of knitted fabrics is an important requirement. In order to improve the thermal insulation property, as close as possible to the body, and not to hinder the movement, the knitted fabric must have a constant load elongation of 50% or more. The elongation at a fixed load is 60% to 100%. In addition, in order to maintain close contact with the body, excellent recovery properties, and not to impair aesthetics, it is preferable that the elongation recovery ratio under constant load is 50% or more. It is preferably 60 to 95%. φ A mixture of elastic yarn and non-elastic fiber is used to form a composite yarn, and the method of knitted fabric or the method of interlacing elastic yarn and non-elastic yarn is used. However, when weaving, it is preferable that the surface on the surface of the knitted fabric is not directly elastic. Because the surface of the hygroscopic fiber is sticky due to hygroscopicity, it does not substantially absorb a large amount of moisture, and the skin does not feel the sticky feeling of non-elastic fibers. The method of forming a composite yarn is a method of a composite spinning yarn or a covered yarn. A specific method for forming a composite spinning yarn is, for example, a method for making an elastic yarn at an appropriate draw ratio in a roving pulling range in a worsted spinning process of a non-elastic fiber to form a core -25- 200404109 composite yarn. Specific examples of the method for forming the covered yarn include a method in which an elastic yarn is supplied at an appropriate draw ratio and a non-elastic yarn is wound thereon. In this case, wool, cotton, linen and polyester staple fibers, and nylon staple fibers can be used as the non-elastic fibers. In the latter case, textile yarns of silk, polyester monofilament, durable monofilament, cotton and wool can be used. It can also be used as a composite false twist yarn when it is a polyester single yarn or a nylon single yarn. These composite yarns can be used alone or interwoven with other fiber yarns. As circular knitted fabrics, they have the advantage of greater elongation in knitted fabrics. The extension of the tissue system can meet the necessary conditions, and there is no particular limitation. For warp knitted fabrics, especially after the supply of non-elastic single yarns that form needles, even if elastic yarns are used in any yarns, because elastic yarns can be formed by surrounding non-elastic single yarns to form knitted fabrics, elastic yarns can be bare. yarn. In this case, a non-elastic yarn may be used as a spinning yarn, but a single yarn is preferable when the workability of the fluff or wind-fiber is suppressed. The knitted fabric of the present invention is suitable for use in underwear. Knitted fabrics suitable for underwear are characterized by their ability to absorb moisture, and to produce heat and heat when they absorb moisture. This is also the same in the invention of the stockings mentioned 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 needles of the knitted fabric of the tights, and this change affects comfort. When the body temperature rises due to the stimulation of sports during wearing, in order to cool the body temperature and emit sweat from the skin surface, the temperature and humidity of the gas phase containing the needles rise at the same time, which causes discomfort. 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 absorption moisture is released from the fiber surface to the outside environment. When heat is generated during moisture absorption, the moisture content in the gas phase rises only by the same temperature, and the relative humidity decreases, and it promotes -26- 200404109 sweating from the skin '. As a result, the decrease in body temperature is suppressed. This phenomenon continues for several minutes until the bodysuit reaches a state of moisture absorption equilibrium. Finally, the amount of moisture absorption and dehumidification reached equilibrium, and the heating effect was stopped. At this time, the temperature of the bodysuit dropped to reach the equilibrium temperature. When exercise is stopped and sweating is stopped, only dehumidification will be performed, and the best state will be reached. 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 release speed becomes slower and the moisture absorption reaches a high level. As a result, the heat generation and heat release continue for a long time in a mild state, and it is particularly effective to suppress After the sweating stops, the fiber temperature decreases slowly, which suppresses the cold feeling after the exercise stops. The present inventors have repeatedly studied and reviewed the change in the hygroscopic fine particle concentration in the elastic yarn, and the heating effect when absorbing moisture can be felt in a wearing test. As a result, it can be confirmed that the heating rate must be 5 ° C / min or more. ability. It is more preferably 7 ° C / min or more. The lower the temperature outside, the higher the heating capacity is. The knitted fabric used in tight underwear of the present invention can be made of the above-mentioned typical elastic yarn of polyurethane-based elastic fibers and non-elastic fibers such as polyester-based fibers, polyamide-based fibers, and cellulose-based fibers. For stretch knitted fabrics, a thin round yarn is used. In order to form a thin, rich-looking knitted fabric, a single yarn of polyester-based fibers or polyamide-based fibers is preferred. The knitting structure is a circular knitting plain fabric, a double-sided texture, a refined texture, a double-reverse texture, or a knitting knitted fabric, such as a tricot knitted fabric, a Russell twill knitted fabric, and the like. There are no particular restrictions. For tricot knitted fabrics, such as semi-weave, inverse half-tissue, double carded warp plain weave, double carded warped forged weave, and for Russell twill knit, such as elastic knitted fabric, semi-elastic knitted fabric, satin Knitted fabric. Warp knitted fabrics and so on. 200404109 Elastic yarns and non-elastic fibers can also be used as composite yarns of covered yarns, twisted yarns, composite yarns, and the like, as well as bare yarns that can interweave non-elastic fibers with polyurethane elastic yarns. If desired, the composite can also be interwoven with non-elastic yarns. In order to reduce processing costs, it is better to interweave with bare yarn. Furthermore, in order to reduce the rubbery feel of the knitted fabric or the sticky feeling when it absorbs moisture, it is preferable that the surface layer of the knitted fabric is covered with non-elastic fibers. At this time, in order to fully utilize the moisture absorption and heat generation, moisture release, antibacterial, deodorizing performance and stretchability of the knitted fabric, the content of the elastic fiber is preferably 10% by weight or more. More preferably, it is 20 to 50% by weight. If it is more than 50% by weight, not only the economy is not good, but also the texture such as flexibility and swelling may be reduced, so it is not desirable. The temperature difference between the moisture absorption and heating characteristics of the knitted fabric of the present invention at the initial stage and 10 times after laundering is less than 1 ° C. If it is less than 1 ° C, it means that it has laundering durability and can maintain the moisture absorption after 10 launderings. Heating characteristics. The knitted fabric of the present invention is suitable for use in tight underwear. Since the elastic resin contains the above-mentioned highly hygroscopic organic fine particles, it can form a wearing comfort with high stretchability or moisture absorption and heat generation, heat release and heat generation, and electrical performance. Yueju, a multifunctional stretch knit with hygienic function of deodorizing effect and moisturizing function by p Η 値 cushioning performance. The present invention encompasses the invention of tight underwear. Next, the pantyhose of the present invention will be described. The characteristics of the pantyhose of the present invention are that it has moisture absorption energy, and has the effects of heating and heating when it absorbs moisture. First, the temperature and humidity change of the pantyhose according to the present invention is about the same as that of a knitted fabric suitable for tight underwear. The inventors conducted a review. By changing the high hygroscopicity and fine particle concentration in the elastic yarn, the warming effect of the pantyhose wearing test was felt when the hygroscopicity was felt. The result was 200404109. It is known that the heating ability is better than 7 ° C / min. . More preferably, it is 9 ° C / min or more. The lower the external temperature, 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, extensibility, and elongation recovery, or an interwoven knitted fabric of the composite yarn and a false twist processing yarn of the synthetic fiber yarn. good. The elastic yarn is preferably an elastic single yarn. Synthetic fiber yarns are preferably synthetic single yarns. The front and back surfaces of the pantyhose are preferably covered with a substantially synthetic single yarn. This system avoids direct contact between the elastic yarn and the skin, and has good smoothness with the skin surface, so it can meet the better characteristics of pantyhose. When both sides of the composite yarn are single yarns, the transparency, the strength, and the wearing durability are improved. Therefore, the synthetic single yarns are preferably polyester or nylon. In terms of hygroscopicity and durability, synthetic single yarns are more resistant to dragon single yarns. The total fineness of the composite yarn is substantially 30 to 80 denier for the pantyhose portion, and preferably 10 to 50 denier for the foot portion. The difference between the initial hygroscopic and hygroscopic heating characteristics after 100 washings has the durability of washing and is less than 1 ° C, which means that the hygroscopic and heating properties that can maintain body sensation even after 10 washings are maintained. The laundering of the present invention refers to the laundering using the standard lotion of the Fiber Evaluation Technology Association and the method of r IS-0 2 1 7-103. It is preferable that the elastic yarn containing highly absorbent, absorbent, and absorbent organic fine particles contains 20% by weight or more to constitute a knitted fabric. If it is smaller than this range, the absorbent and absorbent characteristics are insufficient, and odor may occur, which is not desirable. In addition, the tightness of stockings is insufficient, and it is not desirable. More preferably, it is 25 to 40%. In the case of pantyhose, the pants and feet are generally made of different yarns. There is no problem when the two are composed of the same yarn, but when only one side uses the elastic yarn containing the hygroscopic organic fine particles, it means the proportion of the elastic yarn containing the hygroscopic organic fine particles in only the knitting portion of the portion. -29- 200404109 In order to make changes in the environment, the knitted fabric with repeated absorption and release of heat and moisture can be used on the trousers and feet separately. The tights can be designed according to the season and environment. For example, summer pantyhose is made of elastic yarn containing heat-absorbing hygroscopic organic particles only on the foot, so that cool pantyhose with a refreshing feeling can be obtained; it is better to use it on both the trousers and the feet in winter. The tights of the present invention are preferably characterized by having at least one kind of deodorizing rate selected from the group consisting of ammonium, acetic acid, and isovaleric acid. These components are those that are used by the Fiber Evaluation Technology Agreement of the Consortium as the odor components of sweat. If they have the ability to eliminate the odor of these components, they will have deodorization for any of the above three components. When it is capable, it is easy to have the ability to eliminate the odor after sweating. The goal of this property is 70% or more. Therefore, if it is less than 70%, the performance is insufficient and it cannot be said that it has deodorizing performance. The better is 85% or more, and the better is more than 90%. In the pantyhose of the present invention, the deodorization rate of at least one selected from the group consisting of ammonium, acetic acid, and isovaleric acid before washing and after washing is preferably 70% or more. The conventionally known stockings have a deodorizing component attached to them after forming the product, and are almost completely post-processed products. These are not good in washing durability. For example, although they have deodorizing ability in the initial stage, they have deodorizing performance after washing. deterioration. The preferred elastic yarn used in the stockings of the present invention is integrated with the fiber on the surface and inside of the fiber, so its performance will not deteriorate at all even after washing. The better range of deodorization rate after washing is 80% or more, and the best is more than 85%. In the stockings of the present invention, it is preferable that the frictional band voltage is 2500 V or less. If the frictional belt voltage is more than 25 00V, it is easy to stick to it when wearing a skirt, especially when it is worn in winter with low humidity. The preferred range is 2000 V or less, and more preferably 1500 V or less. -30- 200404109 In the present invention, it is preferable that the half-grid period of w voltage is 50 seconds or less. Wet friction belt voltage Similarly, the half-life of the belt voltage is a parameter for evaluating the entanglement easiness. When the number is less than 50 seconds, for example, static electricity is caused by friction between the left and right stockings and skirts and the outside, due to the decrease in the voltage. Fast, so it is not easy to have discomfort. If it is longer than 50 seconds, especially when wearing it in winter with low humidity, Easy to feel uncomfortable. It is preferably 30 seconds or less, and more preferably 15 seconds or less. Next, the fabric of the present invention will be described. First, the invention concerning a fabric containing many long fibers (hereinafter referred to as a long fiber fabric) will be mainly explained. The long-fiber fabric of the present invention is a fabric containing a composite yarn of inelastic fibers and the above-mentioned elastic fibers. The constant load elongation is 15% or more, and the fixed load elongation recovery is more than 35%. The surface of the fabric rises when it absorbs moisture. Fabrics with a temperature of 1 t or more are preferred. In the present invention, the elongation at a constant load, the elongation at a constant load, and the temperature of the surface of the fabric at the time of moisture absorption are measured by the following methods. The elongation characteristics of long-fiber fabrics are important characteristics required for clothing, especially sports clothing. When the fabric of the present invention is to obtain a cloth that is easy to move, the constant load elongation is 15% or more, and preferably 20% or more. The upper limit of the elongation at constant load is preferably about 40% when the shape retention and elongation recovery are not reduced. In addition, the long-fiber fabric of the present invention has a fixed load elongation recovery rate of 35% or more, and more preferably 60% or more, without impairing the appearance. The upper limit of the elongation recovery rate under constant load is not particularly limited and is about 95%. In addition, when the long-fiber fabric of the present invention absorbs moisture, the surface temperature of the fabric rises to 1 C or more, and 2 ° c or more in the case of the best parent. The rising temperature of the surface of the fabric during moisture absorption 200404109 The higher the better, it is usually up to about 5 ° C, which is sufficient. By increasing the temperature of the surface of the fabric during the moisture absorption to the above-mentioned range, the fabric will feel warm when worn. Fabrics containing composite yarns of the above non-elastic fibers and elastic fibers, with a constant load elongation of 15% or more, a constant load elongation recovery of more than 35%, and a fabric surface with a temperature rise of 1 ° c or more during moisture absorption. It was prepared by the following method. In other words, it is a woven fabric containing 5% by weight of a composite yarn containing non-elastic fibers and highly hygroscopic fine particles of elastic fibers, and by adapting the traction rate, weaving structure, and weaving density of the composite yarn, the above can be obtained Number of fabrics. The elongation at constant load and the elongation at constant load can be adjusted up or down by adjusting the traction rate, weaving structure and weaving density of the composite yarn, and the content of the composite yarn in the fabric. Moreover, the rising temperature of the fabric surface during moisture absorption can be increased or decreased by adjusting the content of fine particles in the elastic yarn and the content of the composite yarn in the fabric. The texture of the constituent yarn varies depending on the type or use of the constituent material. The fineness of the elastic yarn is usually 20 to 100 dtex, preferably 30 to 50 dtex. When it is within the above range, the elongation characteristics and recovery characteristics of the obtained fabric are good. In the long-fiber fabric of the present invention, the non-elastic fiber refers to a fiber having a breaking elongation specified by JIS L 10 13 (2000) (constant speed elongation test) of 100% or less. The type of the inelastic fiber is not particularly limited, and conventional fibers can be used. The conventional non-elastic fibers such as synthetic fibers of polyamide (Nylon, etc.), polyester, vinylon, acrylic, polyethylene, polypropylene; regenerated fibers of thorium, copper amine; acetate, promex Semi-synthetic fiber; natural fiber of silk, etc. As far as the strength required for sports clothing is concerned, especially single yarns made of polyester and poly-32-200404109 ammonium (Nylon, etc.) are preferred. The inelastic fibers can be used alone or in combination of two or more. The fineness of the yarn made from non-elastic fibers is usually 10 to 100 dtex, especially 20 to 50 dtex. For non-elastic fibers, in terms of obtaining a large volume, a feeling of expansion, and a feeling of warmth, it is better to use a fiber with a large volume processing, and the better is a false twist volume processing yarn. · The form of the composite yarn may adopt a conventional form of a composite form of elastic fibers', which is not particularly limited. This conventional composite yarn system allows elastic fibers to be supplied at an appropriate draw ratio, twists the yarn in a state of being taken out simultaneously with the inelastic fibers, and the obtained layer yarn. In particular, a coated yarn is preferred. In order to improve the covering property by using non-elastic fibers to avoid cutting due to the exposure of elastic fibers, and at the same time to reduce / reduce the friction between fabrics, rolls made using hollow shaft coating machines Yarn). -The twist number of the composite yarn is, for example, 500 to 1,200 T / m, and preferably 600 to 1,200 T / m. When the twist number is in the above range, the elongation recovery characteristics of the composite yarn can be satisfied, and the problem of "needle direction" can be reduced because the surface of the elastic fiber is exposed. The ratio of elastic fiber to non-elastic fiber is based on weight ratio and elastic fiber φ dimension: the ratio of non-elastic fiber is usually 1: 2 ~ 1 ·· 8, preferably 1: 3 to 1: 5 〇 In order to obtain a practically sufficient moisture absorption and heat generating effect in a long-fiber fabric, it is preferable to contain the above-mentioned composite yarn in an amount of 5% by weight or more. In particular, it is preferably 20% by weight or more, and more preferably 25% by weight or more. The fabric can use 100% of the composite yarn as the yarn, but 30% by weight is preferable in terms of maintaining comfort when worn. When the ratio of the composite yarn is within the above range, it is easy to feel the effect of moisture absorption and heat generation when wearing. -33- 200404109 When there are fibers constituting a long-fiber fabric other than the above-mentioned composite yarn, the material is not particularly limited, and synthetic fibers, semi-synthetic fibers, regenerated fibers, and natural fibers can be used. The yarn form may be a single yarn or a spinning yarn. The fibers outside the composite yarn may be non-elastic fibers or elastic fibers. In terms of texture and feel, long fibers using non-elastic fibers are preferred. Fibers other than composite yarns can be used alone or in combination of two or more. * When the fibers outside the above composite yarn are sports fabrics, polyester-based or / and polyamide-based single yarns (especially non-elastic yarns) are preferred. When the fabric is thin and the surface of the fabric is smooth, flat yarn can be used. In this case, the fabric is slightly less stretchable. When it is necessary to use a thicker fabric with a larger elongation, it is preferable to use a large-volume processing yarn for the yarns other than the composite yarn. In particular, a false-twisted yarn (especially a single-stage yarn) using a polyester-based single yarn or a polyamide-based single yarn is preferred. In addition, when aesthetics is required, it is better to use a latent yarn length difference mixed fiber yarn for the yarns other than the above-mentioned composite yarn, and the more preferable is a latent yarn length difference mixed fiber yarn made of a polyester single yarn. When using latent yarns with mixed yarn lengths, the fabric after manufacturing can be lightly reduced in weight using sodium hydroxide or the like to improve the traction and swelling of the texture. Potential yarn length difference mixed fiber yarns can use two or more different types of single shrinkage mixed fiber yarns with thermal shrinkage difference, or spontaneous elongation mixed fiber yarns with single yarns that are stretched by single yarns that are contracted by heat treatment. Further, in the case of underwear or fabric for general clothing, it is preferable to use a flat yarn made of polyester or nylon for the basic yarn other than the composite yarn. Elastic composite yarns can be arranged alternately using both warp and weft yarns, or one of the warp or weft yarns is made of an elastic composite yarn and the other is made of a non-elastic yarn. In the former case, a two-way stretch fabric can be obtained, and in the latter case, a one-way stretch fabric can be obtained. -34- 200404109 Because the long-fiber fabric of the present invention has both hygroscopic and heat-generating properties and stretchability, it is suitable to be used as the inner lining of a sportswear, underwear, general clothing, cold-proof clothing, or a cold-proof outerwear (a lining that can freely fall off) )Wait. There is no particular limitation on the type of clothing using the long-fiber fabric of the present invention. Because it has both hygroscopic and exothermic properties and stretchability, it is suitable for use as sportswear, underwear 'cold-proof outerwear, lining for cold-proof apparel, general clothing, etc. In the case of sportswear ', it is especially suitable for working clothes for outdoor wear. Specifically, the sportswear is, for example, a jersey such as a net jersey, a ski suit, a jogging suit, or pants. Among these, a fabric using a combination of an elastic composite yarn and a non-elastic polyester false twist processing yarn is preferable. General clothing such as shirts or blouses, pants, skirts, coats, etc. Among these, fine-density fabrics (for middle clothing, etc.) made of silk or special single yarns with sweat absorption properties, or fabrics of elastic composite yarns and non-elastic polyester single yarns (for outer clothing, etc.), Or fabrics that combine elastic composite yarns and hetero-shrink mixed fiber yarns (for outerwear, etc.). Fabrics combining elastic composite yarns and hetero-shrink mixed fiber yarns can be used not only as outerwear for jackets in general, but also for sports jackets such as tennis jackets and golf jackets. Underwear such as shirts, shorts, etc. Fabrics such as fine silks made of these silks or special single yarns with sweat-absorbing properties can be used. Long fiber fabrics that combine elastic composite yarns and non-elastic polyester single yarns can be used as the inner lining of outerwear or cold protection clothing for skis. Next, a description will be given of fabrics mainly composed of short fibers (hereinafter referred to as short-fiber fabrics) mainly related to the present invention. However, long fibers are preferred as the elastic fibers.

The upper limit of the load elongation is preferably about 40% so as not to reduce the shape retention and elongation recovery. -Moreover, the short fiber fabric of the present invention has a fixed load elongation recovery rate of 35% or more, preferably 60% or more, without impairing the appearance. The upper limit of the elongation at constant load is not particularly limited, and is about 95%. In the short-fiber fabric of the present invention, the temperature of the surface of the fabric during moisture absorption is 0.5 ° C or higher, preferably 2 ° C or higher. The more the temperature of the fabric surface rises when it absorbs moisture, the better it is. It is usually about 5 ° C, which is sufficient. When it is in the above range, a comfortable clothing which is heated due to moisture absorption and warming can be obtained. In addition, the short-fiber fabric of the present invention has a fluff having a length of 1 mm or more on the surface of the fabric at a density of not less than 0 strips / cm2. The fluff density is preferably at least 20 pieces / cm2. The upper limit of the fluff density is not particularly limited, and is usually 30 pieces / cm2.
