然而，含有尼龍單纖絲之嗜好性飮料萃取用過濾器及 , 嗜好性飲料萃取用袋係有因空氣中的氧而黃變、萃取時因 熱水而尺寸改變、形狀變形、因吸收嗜好性飮料成份而色 調改變、使用後自容器取出袋子時之瀝水差、因尼龍比重 輕而萃取用袋於熱水中之沈降性差、因使用後之燒毀而發 生氮氧化物之環境污染等之問題。 另一方面，作爲含有聚酯系單纖絲之嗜好性飮料萃取 -4 - 200815254 (2) 用過濾器及嗜好性飲料萃取用袋，提出含有經絲及緯絲之 交差點未熔接之織物者，或含有經絲及緯絲之父差點熔接 之織物者等（例如參考專利文獻1、專利文獻2)。 然而，萃取用過濾器爲含有絲之交差部份未熔接之織 物時，雖然觸感柔軟，但製袋萃取用袋時之製袋性或保形 " 性不足。進而，有因織物形狀變型而織眼裂開或茶葉漏出 之問題。另一方面，萃取用過濾器係含有絲之交差部份熔 • 接之織物時，雖然製袋萃取用袋時之製袋性或保形性優異 ，但有觸感堅硬的問題。進而，使用相關的萃取用過濾器 ，得到最近流行之四角形狀之萃取用袋時，若因外來力量 而萃取用袋變形時，因爲萃取用袋變形而不能復原，所以 亦有外觀性差之問題。 另外，具有扁平的斷面形狀之聚酯多纖絲係揭示於專 利文獻3。另外，使用含有鈦化合物及磷化合物之觸媒所 得之聚酯而成之聚酯多纖絲係揭示於專利文獻4。另外， Φ 四角形狀之嗜好性飮料萃取用袋係揭示於專利文獻5。 〔專利文獻1〕專利第345995 1號公報 ^ 〔專利文獻2〕專利第3459952號公報 . 〔專利文獻3〕國際公開W02004/009889號手冊 〔專利文獻4〕國際公開W02004/063435號手冊 〔專利文獻5〕特開平5 — 1 93 6 1 5號 【發明內容】 發明之揭示 -5- 200815254 (3) 本發明之目的係以提供具有柔軟觸感，而且 飮料粉末不易漏出之嗜好性飲料萃取用過濾器， 嗜好性飲料萃取用過濾器而成之嗜好性飲料萃取 的。上述目的係可由本發明之嗜好性飲料萃取用 嗜好性飲料萃取用袋而達成。 本發明之嗜好性飲料萃取用過濾器係.以聚酯 所構成，具有織物組織或編物組織之嗜好性飮料 # 濾器，上述之聚酯系單纖絲係含有具有扁平的斷 聚酯系單纖絲爲特徵之嗜好性飮料萃取用過濾器 在此，上述聚酯系單纖絲之單絲纖度係以: 6Odtex之範圍內爲宜。另外，上述之具有扁平的 之聚酯系單纖絲中，由扁平的斷面形狀之長邊中 之長度B相對於與此長邊中心線方向交差成直角 最大幅度C1之比B/C1所表示之斷面扁平度係於 範圍內爲宜。另外，上述之具有扁平的斷面形狀 ^ 單纖絲之扁平斷面中，每單側形成2個以上之凹 度之最大値C 1相對於最小値C2之比C 1 /C2係方 ~4.00之範圍內爲宜。上述之具有扁平的斷面形狀 -單纖絲係以融點爲255至265°C之範圍之聚對苯 二醇酯所形成爲宜。另外，上述之具有扁平的斷 聚酯系單纖絲中’該聚酯系單纖絲係具有芯鞘結 份係以融點爲25 5至265 °C之範圍之聚對苯二甲 酯所形成，另一方面，鞘成份係以融點爲1 70至 範圍之與間苯二甲酸共聚合之聚對苯二甲酸乙二 ，嗜好性 及使用該 用袋爲目 過濾器及 系單纖絲 萃取用過 面形狀之 〇 於 10至 斷面形狀 心線方向 之方向中 2至6之 之聚酯系 處，其幅 令1.05至 之聚酯系 二甲酸乙 面形狀之 構，芯成 酸乙二醇 240它之 醇酯所形 -6 _ 200815254 (4) 成爲宜。 構成本發明之嗜好性飲料萃取用過濾器之聚酯系單纖 絲中，作爲其他聚酯系單纖絲，以包含具有圓的斷面形狀 之聚酯系單纖絲爲宜。以包含單絲纖度於10至60dtex之 範圍之具有圓的斷面形狀之聚酯系單纖絲尤佳。相關之具 1 有圓的斷面形狀之聚酯系單纖絲係具有芯鞘結構，芯成份 係以融點爲25 5至265 t之範圍之聚對苯二甲酸乙二醇酯 # 所形成，另一方面，鞘成份係以融點爲1 7 0至2 4 0 °C之範 圍之與間苯二甲酸共聚合之聚對苯二甲酸乙二醇酯所形成 爲宜。 本發明之嗜好性飲料萃取用過濾器中，聚酯系單纖絲 係以不含有平光劑爲宜。另外，聚酯系單纖絲中，真比重 爲5.0 g/cm3以上之金屬元素含量爲0.5重量ppm以下爲宜 〇 本發明之嗜好性飲料萃取用過濾器中，嗜好性飮料萃 ® 取用過濾器係具有織物組織，而且，經絲密度爲30至300 條/2.54cm，而且，緯絲密度爲30至300條/2.54cm之範 ^ 圍內爲宜。另外，嗜好性飮料萃取用過濾器係具有平織物 組織爲宜。另外，嗜好性飲料萃取用過濾器亦可具有網眼 編物組織。另外，嗜好性飲料萃取用過濾器之開口率係於 40至75 %之範圍內爲宜。另外，嗜好性飲料萃取用過濾器 中，構成過濾器之單纖絲係以至少部份的交差部份熔接爲 宜。此時，單纖絲之交差部份係以格子圖樣熔接爲宜。 本發明之嗜好性飲料萃取用袋係使用上述之嗜好性飲 200815254 (5) 料萃取用過濾器而成之嗜好性飮料萃取用袋。作爲相關的 嗜好性飮料萃取用袋係具有四角形狀爲宜。 用以實施發明之最佳形態 本發明之嗜好性飲料萃取用過濾器係以聚酯系單纖絲 ^ 所構成’而且，具有織物組織或編物組織之嗜好性飮料萃 取用過濾器，該過濾器係含有具有扁平的斷面形狀之聚酯 φ 系單纖絲。 本發明之嗜好性飲料萃取用過濾器係由含有相關之具 有扁平的斷面形狀之聚酯系單纖絲，與相同纖度之圓形斷 面或三角斷面等之不具有扁平形狀之單纖維之過濾器比較 ’藉由扁平斷面之效果，可以不提高過濾器之密度而縮小 開口率。該結果係可得到具有柔軟觸感，而且，嗜好性飲 料粉末難以漏出之嗜好性飮料萃取用過濾器。 聚酯系單纖絲之單絲纖度係於10至60dtex(以10至 • 40 dtex爲宜，以20至35 dtex尤佳）之範圍內爲宜。該單 絲纖度若大於60dtex時，過濾袋的厚度變大，而有損害 ‘ 柔軟觸感之虞。相對地，該單絲纖度若小於lOdtex時， - 有不能得到充分的單纖絲強度之虞。進而，若不充分提高 過濾器之製織或製編密度時，則嗜好性飲料粉末有容易漏 出之虞，提高密度時，製織或製編之難易度變高，有成本 變高之虞。 上述之具有扁平的斷面形狀之聚酯系單纖絲中，扁平 的斷面形狀之長邊中心線方向之長度B相對於與此長邊中 200815254 (6) 心線方向交差成直角之方向中最大幅度C 1之比B/C 1所表 示之斷面扁平度係於2至6之範圍內（以3.1至5.0爲宜） 之範圍內爲宜。該斷面扁平度若小於2時，有不能得到如 上述之斷面扁平之效果之虞。相反地，斷面扁平度若大於 6時，有變得難以製造之虞。 另外，於上述之具有扁平的斷面形狀之聚酯系單纖絲 之扁平斷面中，如圖1之模式所示，每單側形成2個以上 H (以3至5個爲宜）之凹處，其幅度之最大値C 1相對於最 小値C2之比C1/C2係於1·05至4·00(以1.1至1.5尤佳） 之範圍內爲宜。另外，於圖1所示之斷面1中，3個凹處 對於長邊中心線形成對稱。凹處對於長邊中心線雖以形成 對稱爲宜，但即使非對稱亦無妨。如此地形成凹處時，因 爲溝槽成爲導水構，所以浸漬含嗜好性飲料萃取用過濾器 之嗜好性飲料萃取用袋於熱水或冷水使用時，嗜好性飮料 萃取用袋容易沈降，所以適宜。進而，單纖絲之長邊方向 • 形成構槽，即使斷面扁平度變大，聚酯系單纖絲不易發生 扭曲，配置具有扁平的斷面形狀之聚酯系單纖絲於織物之 經絲或緯絲時，以相當於扁平斷面長邊之部份側面朝向織 物表面之狀態容易配置，即使使用具有扁平的斷面形狀之 聚酯系單纖絲，仍具有不易引起因纖維扭曲之織物開口率 不齊之效果。 作爲形成上述之聚酯系單纖絲之聚酯系聚合物，係由 二羧酸成份及二甘醇成份所製造。作爲二羧酸成份，主要 係使用對苯二甲酸爲宜，作爲二甘醇成份，主要使用1種 200815254 (7) 以上選自乙二醇、丙二醇及丁二醇之伸烷基二醇爲宜。其 中，以融點爲255至265 °C之範圍之聚對苯二甲酸乙二醇 酯爲宜。另外’聚酯系聚合物中，可含有上述二羧酸成份 及甘醇成份之外之第3種成份。作爲該第3種成份，可使 用1種以上之對苯二甲酸以外之二羧酸，例如間苯二甲酸 、萘二羧酸、己二酸、癸二酸；及伸烷基二醇以外之甘醇 化合物’例如二乙二醇、聚乙二醇、雙酚A、雙酚磺酸。 其中酸成份係由莫耳比（對苯二甲酸/間苯二甲酸）90/5至 8 5/1 5之對苯二甲酸及間苯二甲酸所形成，甘醇成份係由 乙一醇所形成’由融點爲170至240 °C (以180 °C至220 °C) 之共聚聚酯所形成爲宜。聚酯系單纖絲若具有相關融點時 ’如後述之單纖絲彼此間熔接時，熔接變得容易，所以適 合。 另外’聚酯系單纖絲係具有芯鞘結構，芯成份係以融 點爲255至265 °C之範圍之聚對苯二甲酸乙二醇酯所形成 ，另一方面，鞘成份係以融點爲1 7 0至2 4 0 °C (以1 8 0 °C至 2 2 0 °C尤佳）之範圍之與間苯二甲酸共聚合之聚對苯二甲酸 乙一醇酯所形成爲且。關於該鞘成份之融點，可由調整共 聚合之間苯一甲酸的量而控制。在此，該融點低於1 7 〇。〇 時’如後述之熔接單纖絲彼此間時，雖可容易熔接，但單 纖絲之纖維強度降低，製絲性變差，製織步驟之步驟通過 性有變差之虞。相反地，鞘成份之融點若高於24〇 時， 熔接性變差’有不能得到充分的黏合力之虞。另外，芯部 及鞘部之體積比係前者：後者於8 〇 : 2 0至2 0 : 8 0之範圍 -10- 200815254 (8) 內，以70: 30至30 :70之範圍內爲宜，以60: 40至40 :60之範圍內尤佳。另外，芯成份之體積比率若未滿50% 時，因爲有單纖絲之纖維強度降低’製絲性變差，製織步 驟之步驟通過性變差之虞，保持芯成份之體積比率於50% 以上時，更加適宜。 另外，上述之聚酯系聚合物中，平光劑之含量係以 0.1重量％以下爲宜。尤其平光劑係以不含聚酯系聚合物 Φ 爲宜。於聚酯系聚合物中不含氧化鈦等之平光劑時，因爲 聚酯系單纖絲變成透明，嗜好性飲料萃取用袋中之茶葉等 之嗜好性飮料粉末可自外部看見，演出高級感，所以適宜 如上述之具有扁平的斷面形狀之聚酯單纖絲係使用如 上述之聚酯系聚合物，例如國際公開 W02004/009889號 手冊所揭示之紡絲方法而可容易得之。此時，可作爲單纖 絲紡絲·延伸，亦可作爲多纖絲紡絲·延伸後，分纖成單 纖絲。另外，於聚酯系聚合物中，真比重爲5.0 g/cm3以上 之金屬元素含量係以0 · 5重量PPm以下爲宜。尤其，真比 重爲5.0g/cm3以上之銻或鍺等之金屬係以不含於聚酯系聚 合物中爲宜。真比重爲5.0 g/cm3以上之金屬元素若含於聚 酯系聚合物中時，使用嗜好性飮料萃取用過濾器時，相關 金屬有溶出之虞。另外，該聚酯系聚合物係如國際公開 W02004/06343 5號手冊所揭示，使用含鈦化合物及磷化合 物之觸媒而可得之。 於本發明之嗜好性飲料萃取用過濾器中，作爲上述之 -11 - 200815254 (9) 具有扁平的斷面形狀之聚酯系單纖絲之混合率，並無特別 的限定，但該混合率愈高，可得到柔軟觸感，而且，嗜好 性飲料粉末不易漏出之嗜好性飲料萃取用過濾器爲宜。作 爲該混合率，以30重量％以上爲宜，以50重量％以上尤 佳，以100重量％最好。 ^ 本發明之嗜好性飲料萃取用過濾器中，含有圓形斷面 或三角斷面等之非扁平之聚酯系單纖絲作爲其他單纖絲時 • ，作爲相關的其他聚酯系單纖絲，以具有圓形斷面形狀之 聚酯系單纖絲爲宜。尤其含有單絲纖度爲10至60dtex之 範圍之圓形斷面形狀之聚酯系單纖絲爲宜。作爲相關的具 有圓形斷面形狀之聚酯系單纖絲，芯成份係以融點25 5至 265 °C之範圍之聚對苯二甲酸乙二醇酯所形成，另一方面 ，鞘成份係以融點爲1 70至240°C之範圍之與間苯二甲酸 共聚合之聚對苯二甲酸乙二醇酯所形成。採用相關單纖絲 作爲其他單纖絲時，熔接單纖絲彼此間時，可容易熔接。 • 另外’形成相關其他單纖絲之聚酯系聚合物，亦基於與上 述相同理由’以不含有平光劑爲宜。進而，形成其他單纖 • 絲之聚酯系聚合物所含之真比重爲5.0g/cm3以上之金屬元 „ 素之含量爲0.5重量ppm以下，基於與上述相同理，所以 適宜，與上述之理由相同。另外，芯部及鞘部之體積比係 前者：後者爲80: 20至20: 80之範圍內，以7 0: 3 0至 30: 70之範圍內，以60: 40至40: 60之範圍內爲宜。另 外，芯成份之體積比率若未滿50%時，因爲有單纖絲之纖 維強度降低，製絲性變差，製織步驟之步驟通過性變差之 •12- 200815254 (10) 虞，所以芯成份之體積比率係以保持50%以上尤佳。 本發明之嗜好性飮料萃取用過濾器中，過濾器可具有 織物組織或編物組織，該織編組織並無特別的限制。例如 ，採用織物組織，如於織物之經絲及緯絲中配置上述之具 有扁平的斷面形狀之聚酯系單纖絲之織物、於織物之經絲 ^ 及緯絲中之任一方配置上述之具有扁平的斷面形狀之聚酯 系單纖絲，另一方則配置非扁平之聚酯系單纖絲之織物、 # 於織物之經絲及/或緯絲，交互地配置上述之具有扁平的 斷面形狀之聚酯系單纖絲及非扁平之聚酯系單纖絲之織物 等爲宜。作爲織物之織組織係以平織組/織爲宜。另外，作 爲編物之編組織係以網眼編物組織。 另外，作爲織編組織之密度，經絲密度爲3 0至3 00 條/2.54cm(以60至180條/2.54cm爲宜，以80至130條 /2.54cm尤佳），而且，緯絲密度爲30至300條/2.54cm(以 50至170條/2.54cm爲宜，以60至120條/2.54cm尤佳） ® 之範圍內爲宜。密度比相關範圍大時，有損及柔軟觸感之 虞。相反地，密度比相關範圍小時，有嗜好性飲料粉末變 * 得容易漏出之虞。 ' 另外，作爲過濾器之開口率，係於4 0至7 5 %之範圍 內爲宜。該開口若大於75 %時，有嗜好性飲料粉末變得容 易漏出之虞。該開口若小於40%時，則有損柔軟觸感之虞 〇 本發明之嗜好性飮料萃取用過濾器，使用至少具有上 述扁平的斷面形狀之聚酯系單纖絲，因應需要，亦可使用 -13- 200815254 (11) 非扁平聚酯系單纖絲，由通常之織機或編機而可容易製編 織。 另外，於所製編織之嗜好性飲料萃取用過濾器，構成 過濾器之單纖絲係以至少部份的交差部份熔接爲宜。例如 過濾器具有織物組織時，係以經絲與緯絲之至少部份的交 ' 點熔接爲宜。另外，過濾器具有編物組織時，相鄰線圏彼 此間係以至少部份熔接爲宜。如此地至少部份的單纖絲之 Φ 交差部份熔接時，使用嗜好性飲料萃取用過濾器，製袋嗜 好性飲料萃取用袋時，提昇製袋性或保形性，另外，於切 斷之端面，不易發生鬆亂，所以適宜。 如此的單纖絲之交差部份之熔接係可全部的交差部份 熔接，亦可於縱橫格子、斜面格子、條紋等所定的模式熔 接。其中，就得到更好的柔軟觸感上，以格子狀模式熔接 爲宜。另外，本發明之嗜好性飲料萃取用過濾器中，因爲 含有上述之具有扁平形狀之聚酯系單纖絲，所以即使全部 Φ 的交差部份熔接，亦不損害柔軟觸感。另外，熔接全部的 交差部份係於加熱成所定溫度之加熱空氣中，將過濾器熱 -

The filter has a soft touch and a hobby powder which is not easy to leak. The filter for extracting the hobby beverage and the bag for extracting the hobby beverage using the filter for extracting the hobby beverage. [Prior Art] Conventionally, a filter for extracting a favorite beverage used as a favorite beverage such as green tea or black tea is mainly composed of a nonwoven fabric or paper formed of a polyolefin fiber or a polyester fiber. By. In recent years, it has been proposed to use a nylon monofilament or a polyester monofilament to woven a mesh fabric of a plain weave to form a filter for extracting a favorite beverage. The Φ bag for the hobby beverage extraction using the filter formed by the related mesh fabric is characterized by the high-grade feeling of the tea leaves inside the bag from the outside, and further characterized by the scent or the extractability. - However, the filter for the extraction of the taste of the nylon monofilament and the bag for the extraction of the hobby beverage are yellowed by the oxygen in the air, the size of the water is changed during the extraction, the shape is deformed, and the absorption is good. The color of the tanning material is changed, the color difference is poor when the bag is taken out from the container after use, the sedimentation property of the extraction bag in the hot water is poor due to the light specific gravity of the nylon, and the environmental pollution of nitrogen oxides occurs due to burning after use. . On the other hand, it is extracted as a favorite material containing polyester monofilament - 4 - 200815254 (2) A bag containing a filter and a favorite beverage is extracted, and a fabric containing unconformed warp and weft is proposed. Or a fabric including a warp and a weft of a warp and a weft, etc. (for example, refer patent document 1 and patent document 2). However, when the filter for extraction is a fabric which is not welded to the cross portion of the yarn, the handle is soft, but the bag making property or the conformal property is insufficient when the bag for bag extraction is used. Further, there is a problem that the woven eye is cracked or the tea leaves are leaked due to the shape change of the fabric. On the other hand, when the filter for extraction contains a fabric in which the cross-section of the yarn is melted, the bag-making extraction bag is excellent in bag-making property or shape retention property, but has a problem of hard touch. Further, when the extraction bag for the four corners is obtained by using the related extraction filter, when the extraction bag is deformed by the external force, the extraction bag is deformed and cannot be restored, so that the appearance is poor.

[Patent Document 3] International Publication No. WO2004/009889 Handbook [Patent Document 4] International Publication No. WO2004/063435 Handbook [Patent Document 5] Japanese Patent Laid-Open No. Hei 5 No. 1 9 6 6 No. 5 [Invention] The disclosure of the invention -5 - 200815254 (3) The object of the present invention is to provide a hobby beverage extract filter which has a soft touch and which is difficult to leak out of the mash powder, and a hobby beverage extract filter. The above object can be attained by the bag for the extraction of a favorite beverage for the favorite beverage of the present invention. The invention relates to a filter system for extracting a hobby beverage. A polyester-based monofilament composed of a polyester fabric having a woven fabric or a knitted fabric, and the above-mentioned polyester monofilament yarn contains a filter for extracting a beneficiary material having a flat polyester-based monofilament. Therefore, the monofilament fineness of the above polyester monofilament is preferably in the range of 6 Odtex. Further, in the above-mentioned flat polyester monofilament, the ratio B of the long side of the flat cross-sectional shape to the longitudinal center line direction is a ratio of the right angle C1 to the maximum amplitude C1. It is preferred that the flatness of the section is within the range. Further, in the flat cross section having the flat cross-sectional shape of the single filament, the ratio of the maximum 値C 1 to the minimum 値C2 of the two or more concavities per one side is C 1 /C2 ～4 . Within the scope of 00 is appropriate. The above-mentioned flat cross-sectional shape - monofilament is preferably formed by polyparaphenylene glycol ester having a melting point of 255 to 265 °C. Further, in the above-mentioned flat polyester-based monofilament, the polyester-based monofilament has a core-sheath phase with a poly(p-phenylene terephthalate) having a melting point of 25 to 265 °C. Formation, on the other hand, the sheath component is a polyethylene terephthalate copolymerized with isophthalic acid at a melting point of 1 70 to the range, and the preference and use of the bag as a mesh filter and a monofilament The surface shape of the extracted surface is from 2 to 6 in the direction of the direction of the core line of the cross-sectional shape, and the width is 1. From the 05 to the polyester, the shape of the dicarboxylic acid is in the form of a shape, and the core is formed into an acid glycol. The shape of the alcohol ester is -6 _ 200815254 (4). Among the polyester-based monofilaments constituting the filter for extracting a favorite beverage of the present invention, it is preferable to use a polyester-based monofilament having a circular cross-sectional shape as the other polyester-based monofilament. It is particularly preferable to use a polyester-based monofilament having a circular cross-sectional shape in the range of 10 to 60 dtex. A polyester monofilament having a round cross-sectional shape has a core-sheath structure, and the core component is formed by polyethylene terephthalate # with a melting point in the range of 25 5 to 265 t. On the other hand, the sheath component is preferably formed of polyethylene terephthalate copolymerized with isophthalic acid at a melting point of from 170 to 240 °C. In the filter for extracting a favorite beverage of the present invention, the polyester monofilament preferably contains no flatner. In addition, in the polyester monofilament, the true specific gravity is 5. The metal element content of 0 g/cm3 or more is 0. 5% by weight or less is suitable. In the filter for extracting a hobby beverage of the present invention, the hobby ® extract filter has a woven structure, and the warp density is 30 to 300 /2. 54cm, and, weft density is 30 to 300 / 2. The 54cm range is suitable. Further, the filter for the taste extraction is preferably a flat fabric structure. Further, the filter for extracting a hobby beverage may also have a mesh weave structure. Further, the aperture ratio of the filter for extracting a favorite beverage is preferably in the range of 40 to 75%. Further, in the filter for extracting a favorite beverage, the monofilament constituting the filter is preferably welded at least in part to the intersecting portion. At this time, the intersection of the monofilaments is preferably welded in a lattice pattern. The bag for extracting a hobby beverage of the present invention is a bag for hobby material extraction which is obtained by using the above-mentioned hobby drink 200815254 (5) filter for material extraction. The bag for extracting the related hobby material has a square shape. BEST MODE FOR CARRYING OUT THE INVENTION The filter for extracting a hobby beverage of the present invention is composed of a polyester monofilament, and a filter for extracting a hobby material having a woven structure or a knitted structure, the filter It is a polyester φ-based monofilament having a flat cross-sectional shape. The filter for extracting a hobby beverage of the present invention is composed of a polyester-based monofilament having a flat cross-sectional shape and a single fiber having a flat shape such as a circular cross section or a triangular cross section of the same fineness. The filter comparison 'by the effect of the flat section, the aperture ratio can be reduced without increasing the density of the filter. As a result, it is possible to obtain a filter for the extraction of a hobby material which has a soft touch and which is difficult to leak out of the taste powder. The monofilament fineness of the polyester monofilament is preferably in the range of 10 to 60 dtex (preferably 10 to 40 dtex, particularly preferably 20 to 35 dtex). When the single yarn fineness is more than 60 dtex, the thickness of the filter bag becomes large, which impairs the ‘soft touch. On the other hand, if the single yarn fineness is less than 10 dtex, the sufficient monofilament strength cannot be obtained. Further, if the density of the filter is not sufficiently increased, the taste powder may be easily leaked, and when the density is increased, the ease of weaving or knitting is increased, and the cost is increased. In the above-described polyester monofilament having a flat cross-sectional shape, the length B of the long-side center line direction of the flat cross-sectional shape is at right angles to the intersection of the long-side of the long side of the 200815254 (6) core line direction. The ratio of the maximum amplitude C 1 to the ratio B/C 1 indicates that the flatness of the section is in the range of 2 to 6 (at 3. 1 to 5. 0 is appropriate) within the range. If the flatness of the section is less than 2, the effect of flattening the cross section as described above cannot be obtained. On the other hand, if the flatness of the section is more than 6, it becomes difficult to manufacture. Further, in the flat cross section of the polyester monofilament having a flat cross-sectional shape as described above, as shown in the mode of Fig. 1, two or more Hs (three to five are preferable) are formed on one side. In the recess, the ratio of the maximum 値C 1 to the minimum 値C2 ratio C1/C2 is from 1.05 to 4·00 (in 1. 1 to 1. 5 is particularly suitable for the range. Further, in the section 1 shown in Fig. 1, the three recesses are symmetrical with respect to the center line of the long side. It is advisable for the recess to form a pair for the long-side centerline, but even if it is asymmetrical. When the recess is formed in this way, since the groove is a water-conducting structure, when the bag for extracting the taste-containing beverage containing the filter for extracting the taste drink is used in hot water or cold water, the bag for the extraction of the taste material is likely to settle, so that it is suitable. . Further, the longitudinal direction of the monofilaments is formed into a groove, and even if the flatness of the section becomes large, the polyester monofilament is less likely to be twisted, and the polyester monofilament having a flat cross-sectional shape is disposed on the fabric. In the case of the filament or the weft, it is easy to arrange in a state in which the side surface corresponding to the long side of the flat section faces the surface of the fabric, and even if a polyester monofilament having a flat cross-sectional shape is used, it is less likely to cause distortion due to the fiber. The effect of the fabric opening rate is not uniform. The polyester-based polymer which forms the polyester monofilament described above is produced from a dicarboxylic acid component and a diethylene glycol component. As the dicarboxylic acid component, it is preferred to use terephthalic acid as the diethylene glycol component, and it is preferred to use one of the above-mentioned alkyl diols selected from the group consisting of ethylene glycol, propylene glycol and butylene glycol. . Among them, polyethylene terephthalate having a melting point of 255 to 265 ° C is preferred. Further, the 'polyester polymer' may contain the third component other than the above dicarboxylic acid component and glycol component. As the third component, one or more dicarboxylic acids other than terephthalic acid such as isophthalic acid, naphthalene dicarboxylic acid, adipic acid, and sebacic acid; and alkylene glycol may be used. Glycol compounds such as diethylene glycol, polyethylene glycol, bisphenol A, bisphenol sulfonic acid. The acid component is formed by molar ratio (terephthalic acid/isophthalic acid) of 90/5 to 8 5/15 of terephthalic acid and isophthalic acid, and the glycol component is formed by ethyl alcohol. It is preferred to form a copolyester having a melting point of 170 to 240 ° C (180 ° C to 220 ° C). When the polyester monofilament has a relevant melting point, when the monofilaments to be described later are welded to each other, the welding becomes easy, so that it is suitable. In addition, the 'polyester monofilament has a core-sheath structure, and the core component is formed by polyethylene terephthalate having a melting point of 255 to 265 ° C. On the other hand, the sheath component is melted. a polyethylene terephthalate copolymerized with isophthalic acid in the range of 170 to 240 ° C (especially preferred at 180 ° C to 2 2 0 ° C) and formed . The melting point of the sheath component can be controlled by adjusting the amount of benzoic acid between the copolymerizations. Here, the melting point is below 1 7 〇. When the spliced monofilaments are spliced to each other as described later, the fiber strength of the monofilament is lowered, the yarn-forming property is deteriorated, and the passability of the step of the weaving step is deteriorated. On the other hand, if the melting point of the sheath component is higher than 24 Å, the weldability is deteriorated, and there is a possibility that a sufficient adhesive force cannot be obtained. In addition, the volume ratio of the core portion and the sheath portion is the former: the latter is within the range of 8 〇: 20 to 2 0: 80 0 - 200815254 (8), preferably within the range of 70: 30 to 30: 70. It is especially good in the range of 60:40 to 40:60. In addition, if the volume ratio of the core component is less than 50%, the fiber strength of the monofilament is lowered, the yarn-making property is deteriorated, and the step of the weaving step is deteriorated, and the volume ratio of the core component is maintained at 50%. More than the above. Further, in the above polyester-based polymer, the content of the flatting agent is 0. 1% by weight or less is preferred. In particular, the flatting agent is preferably a polyester-free polymer Φ. When the polyester-based polymer does not contain a flat-lighting agent such as titanium oxide, the polyester-based monofilament becomes transparent, and the taste powder such as tea leaves in the bag for extracting a favorite beverage can be seen from the outside, and the performance is high-grade. Therefore, the polyester monofilament having a flat cross-sectional shape as described above is preferably obtained by using the above-mentioned polyester-based polymer, for example, the spinning method disclosed in the handbook of International Publication No. WO2004/009889. In this case, it can be used as a single filament spinning/extension, or as a multifilament spinning/stretching, and then split into individual filaments. In addition, in the polyester-based polymer, the true specific gravity is 5. The content of the metal element of 0 g/cm3 or more is preferably 0.5 or less by weight of PPm. In particular, the true weight is 5. A metal such as ruthenium or osmium of 0 g/cm3 or more is preferably not contained in the polyester-based polymer. The true weight is 5. When a metal element of 0 g/cm3 or more is contained in a polyester-based polymer, when a filter for extracting a taste material is used, the relevant metal may be eluted. Further, the polyester-based polymer is obtained by using a catalyst containing a titanium compound and a phosphorus compound as disclosed in International Publication No. WO2004/06343. In the filter for extracting a hobby beverage according to the present invention, the mixing ratio of the polyester-based monofilament having a flat cross-sectional shape as described in -11 - 200815254 (9) is not particularly limited, but the mixing ratio is not particularly limited. The higher the viscosity, the softer the touch, and the filter for the extraction of the hobby beverage which is not easily leaked by the hobby beverage powder. The mixing ratio is preferably 30% by weight or more, more preferably 50% by weight or more, and most preferably 100% by weight. ^ In the filter for extracting a hobby beverage of the present invention, when a non-flat polyester monofilament such as a circular cross section or a triangular cross section is used as the other monofilament, it is used as a related other polyester monofilament. The filament is preferably a polyester monofilament having a circular cross-sectional shape. In particular, a polyester-based monofilament having a circular cross-sectional shape having a single-filament fineness of 10 to 60 dtex is preferable. As a related polyester monofilament having a circular cross-sectional shape, the core component is formed by polyethylene terephthalate having a melting point of 25 5 to 265 ° C, and on the other hand, a sheath component It is formed by polyethylene terephthalate copolymerized with isophthalic acid at a melting point of from 1 70 to 240 °C. When the related monofilament is used as the other monofilament, the single filaments can be easily welded when they are welded to each other. • It is also preferable that the polyester-based polymer forming the other monofilaments is not contained in the same manner as described above. Further, the polyester-based polymer forming the other single-fibers has a true specific gravity of 5. The metal element above 0g/cm3 „ the content of the prime is 0. The reason of 5 ppm by weight or less is the same as the above, and is therefore the same as the above reason. In addition, the volume ratio of the core and the sheath is the former: the latter is in the range of 80: 20 to 20: 80, in the range of 70: 30 to 30: 70, and in the range of 60: 40 to 40: 60. The inside is appropriate. In addition, if the volume ratio of the core component is less than 50%, the fiber strength of the monofilament is lowered, the yarn-forming property is deteriorated, and the step of the weaving step is deteriorated. 12-200815254 (10) 虞, so the core The volume ratio of the ingredients is preferably maintained at 50% or more. In the filter for extracting a taste of the present invention, the filter may have a woven structure or a knitted structure, and the woven tissue is not particularly limited. For example, the woven fabric is used, such as a woven fabric of a polyester monofilament having a flat cross-sectional shape in the warp and weft of the woven fabric, and one of the warp and the weft of the woven fabric. a polyester monofilament having a flat cross-sectional shape, and a non-flat polyester monofilament fabric, a warp warp and/or a weft of the fabric, and an alternating arrangement of the above-mentioned flat filaments Preferably, the cross-sectional shape of the polyester monofilament and the non-flat polyester monofilament fabric are suitable. As the woven structure of the woven fabric, a plain weave group/woven is preferred. In addition, the organization of the composition is organized by mesh editing. In addition, as the density of the weaving structure, the warp density is from 30 to 300. 54cm (60 to 180/2. 54cm is appropriate, with 80 to 130 /2. 54cm is especially good), and the weft density is 30 to 300. 54cm (to 50 to 170/2. 54cm is appropriate, with 60 to 120/2. It is suitable within the range of 54cm. When the density is larger than the relevant range, it is detrimental to the soft touch. Conversely, when the density is smaller than the relevant range, there is a tendency for the beverage powder to be easily leaked. In addition, the aperture ratio of the filter is preferably in the range of 40 to 75 %. If the opening is more than 75%, there is a possibility that the taste drink powder becomes easily leaked. When the opening is less than 40%, the soft touch is impaired. The filter for extracting the taste of the present invention uses a polyester monofilament having at least the flat cross-sectional shape, and if necessary, Use -13-200815254 (11) Non-flat polyester monofilament, which can be easily woven by a conventional loom or knitting machine. Further, in the filter for the extraction of the hobby beverage prepared, the monofilament constituting the filter is preferably welded at least in part to the intersecting portion. For example, when the filter has a woven structure, it is preferred to weld at least a portion of the warp and the weft. Further, when the filter has a braided structure, the adjacent strands are preferably at least partially welded to each other. When at least a part of the Φ cross-section of the monofilament is welded, the filter for extracting the hobby beverage is used, and the bag for bag-shaped beverage extraction is improved, and the bag-making property or shape retention property is improved, and in addition, the bag is cut off. The end face is not easy to be loose, so it is suitable. The splices of the intersections of such monofilaments can be welded to all of the intersecting portions, and can also be welded in a pattern defined by vertical and horizontal lattices, beveled lattices, stripes, and the like. Among them, a better soft touch is obtained, and it is preferable to weld in a lattice pattern. Further, in the filter for extracting a favorite beverage of the present invention, since the polyester monofilament having the flat shape described above is contained, even if all the intersecting portions of Φ are welded, the soft touch is not impaired. Further, all the intersecting portions of the fusion are heated in a heated air heated to a predetermined temperature, and the filter may be heat-treated. In addition, when the intersection portion is welded in a predetermined pattern, the filter may be heated by a hot roller having a pattern of the predetermined pattern. Since the filter for extracting a favorite beverage of the present invention contains the polyester monofilament having a flat shape as described above, the effect of the flat cross section can reduce the aperture ratio without increasing the density of the filter. As a result, the filter for extracting a favorite beverage of the present invention has a soft touch and an effect that the drink powder of the taste is not easily leaked. Further, when the intersections of the filaments are welded to each other, -14-200815254 (12), since the contact at the intersection becomes large, welding is facilitated. Next, the bag for the taste extraction of the present invention is a bag for the extraction of a favorite beverage which is obtained by using a filter for extracting a taste material. The related hobby material extraction bag is a bag or a blister bag which is immersed in hot water or cold water. In particular, a bag having a square shape as shown in Fig. 3 is preferred.
