591134 A7 ____ B7 五、發明說明$ ) (請先閱讀背面之注意事項再填寫本頁) 本發明係關於一種連結經擠出之塑膠單絲在其周圍表 面的方法。本發明亦關於一種標記及/或結構性地改變或 修飾經擠出之單絲或單絲團或群之個別單絲的方法。 ' 自實質無規之聚合物擠出而產製單絲。擠出發生在橫 截面上,此適應於單絲之隨後使用。因此,可能產生極薄 的纖維,鬃絲及單紗。、、單絲〃一詞據了解是意指所有經 連續擠出之單絲,其直徑範圍自纖維至工業用之鬃絲,即 使隨後以例示的方式中,主要是針對鬃絲來參考。 在很多例子中,需要具有不同特性之單絲的鬃絲材料 。自二或多單絲所形成之鬃絲的供應迄今仍無法成功,因 爲多核心之鬃絲僅能藉著以不恰當的方式粘合或塗覆而產 製且僅會伴著喪失其特性。在使用期間或至少在其末期, 多核心之經捻的鬃絲已再次令人不想要地分離。在數個起 初個別擠出之單絲間的完整或正嚙合的連結迄今尙未存在 〇 經濟部智慧財產局員工消費合作社印製 對於自不同形式之單絲核所形成的鬃絲有特殊的需要 。如自硬的熱塑性塑膠及軟的彈性體之單絲核心的結合會 有新的效果。此也適用在關於具有磨蝕及非磨蝕作用的單 絲核心的結合方向。經結合之鬃絲作用更特別地肇因於不 同截面之單絲核心的結合,如圓的及多方或其它輪廓之單 絲核心的連接。在很多例子中,若其它單絲核心以螺旋或 橫越,寬的或窄的嚙合方式纏繞在一或多個軸向定位之單 絲核心周圍,則效果可以增加。欲取代圏繞時,可能使用 其它纏繞法。 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) -4 - 591134 經濟部智慧財產局員工消費合作社印製 A7 __B7_ 五、發明說明έ ) 本發明的問題因此是在擠出期間或之後連結任意不同 的聚合物的單絲以形成單絲團。 依本發明,此問題被解決,因爲使用對雷射光束( • L S )具有不同吸收係數的單絲且在其周圍表面上至少帶 狀地接觸且藉採用雷射光束入接觸區中而熔融在一起或正 連結。 雷射源可以是如C 0 2雷射,二極管雷射,銨雷射或激 發雷射。因光束之平行本質及任意地在光罩或偏轉掃描器 之助之下,使用此種雷射,可能產生極精確的定位。若單 絲因材料特性或添加劑之添加而有不同的吸收係數,則單 絲可以在接觸面積上熔在一起且此可以局部地發生。此外 ,藉由雷射,在吸收區中所供應之熱及,因此,熔融體積 可以極精確地控制,以致即使用小的接觸面積也確保熔融 或熔接在一起會在整個接觸面積中發生。 若單絲材料之熔融物不可能(因爲如單絲之一非由熱 塑性材料所形成),則可以得到正連接。由熱塑性材料熔 融物所形成之單絲的材料因雷射光束之採用會膨脹及流動 ,以使不熔或以較不顯著方式熔化之單絲被粘合在其中, 特別是若該單絲不具有平滑表面。 在擠出後,單絲可以在如平行位置上與多核心單絲直 接接觸。單絲亦可能以雙核心,多核心或同心圓形式被同 擠出。在此情況中,因有雷射處理,經由接觸之周圍表面 發生緊密的連接。 關於單絲之產製,已知是要在擠出後將它們拉伸且而 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) --------------------訂---------線 (請先閱讀背面之注意事項再填寫本頁) -5- 經濟部智慧財產局員工消費合作社印製 591134 A7 B7 五、發明說明έ ) 後將它們安定。依本發明之雷射光束的採用可以拉伸前及 /或在拉伸後及/或在安定後發生。特別可以在雷射光束 採用之後使單絲安定。若雷射光束僅在單絲安定後採用, _則實施另外的安定階段。 如已指明的,可能使用由聚合物所製之具有不同L S 吸收係數的單絲且在介面中之L S吸收被利用以供產生熱 量。 然而,較佳地,欲連結在一起之二單絲的至少一者混 合以具有比周圍聚合物更高的L S吸收係數的添加劑。其 可以是二氧化鈦,碳黑及金屬或金屬氧化物,特別是顏料 型者。在此情況中,聚合物在添加劑之直接環境中被熔融 在其上。在某些聚合物及添加物之情況中,熔融方法與微 發泡方法連接,此在很多應用中是想要的,因爲其確保一 較佳的整體嚙合或正嚙合。 此方法亦可以下述方式實施:單絲與添加劑主要用在 接近外層之區域中,以致熔融方法實質限於單絲之介面區 域。 與毛刷產品產製有關者,公知地(D Ε 1 9 6 0 6 4 1 6 A 1 )要在所謂之穿透照射法中藉L S輻射,固定 鬃絲單絲或線束於鬃絲載體之閉塞孔中。L S吸收而後主 要發生在鬃絲端及閉塞孔底部間之介面區域。然而,不能 使用此方法以沿著外層連結單絲。 單絲主要在平行位置中交互連接,然而’至少一單絲 可能藉另一單絲而被纏繞且在接觸面積中連接其至內部的 --------------------訂--------- (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) -6 - 經濟部智慧財產局員工消費合作社印製 591134 A7 B7 五、發明說明ϋ ) 單絲。 本發明進一步問題是要建議一種光學地標記經擠出之 單絲或單絲團之個別單絲的方法。 ’依本發明,此問題被解決,因爲至少欲被標記之(眾 )單絲,伴著在雷射作用下會有顏色改變反應的添加劑的 添加,會進行擠出作用且在對應於所要之標記的面積中受 雷射光束處理。添加劑可以具有不同之雷射吸收特性。 本發明提供一般性地擠出單絲或單絲團中之單絲且隨 後以所要方式將之標記的可能性,因爲在雷射作用下因相 關之所選的添加劑所生之顏色改變被利用。特別可能使標 記作爲順序或標序方法,例如,爲要將以特定方式標記之 特定之毛刷品之鬃絲自鬃絲供應或儲存被帶在一起。此外 ,因有此一標記,可以指明一特定的使用形式且再次地可 以作爲標序方法。此一標記可以在最終之毛刷上特別用來 作爲用途說明。對於如牙刷以及技術或工業用毛刷而言, 這是想要的,以確保毛刷或鬃絲適時地置換。 依標記之功能,欲被標記之單絲可以使用雷射光束, 沿著其外層,以punctiform或線性方式來處理。除此之外, 欲被標記之單絲可以用雷射光束在至少一輻向面上被處理 ’以致當鬃絲磨穿時經標記之輻向面被暴露且表明所需之 替換。 依本發明用雷射光束之處理發生在拉伸前及/或拉伸 後及/或安定後。 特別地,可以在雷射處理後安定單絲。 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) I*---J----------------訂--------- (請先閱讀背面之注意事項再填寫本頁) 591134 A7 B7 五、發明說明6 ) (請先閱讀背面之注意事項再填寫本頁) 關於同心圓地共擠出二種成份以上之單絲,可能提供 具有L S吸收添加劑的一或多種單絲內層。若此僅發生在 預定長度部份且此一單絲用雷射處理,則顏色改變僅發生 '在該長度部份。此亦使得可能完成一刻度或用途說明。 最終’本發明進一步問題是要在單絲擠出後結構性地 修飾單絲或單絲團之個別單絲。結構修飾一詞主要地被了 解成表面及/或內部結構的改變。 爲了解決此問題,欲結構性地修飾之單絲與L S吸收 添加劑同擠出,而後用雷射光處理。 在依本發明處理單絲的情況中,在添加劑及/或在被 雷射輻射影響之添加劑的環境中,形成微泡結構,其可被 使用以供表面結構或亦供結構單絲核心,爲要影響柔軟度 ’液體吸收性等。此發泡過程可以藉相關之添加劑定尺寸 或多成份單絲結構,以及雷射光束之作用深度來局部地定 義或受限。亦可利用微泡形成以諸如在共擠出單絲之情況 中膨脹內部或外部的單絲且隨後利用在二單絲之僅一者中 結構的改變或改良單絲團。 經濟部智慧財產局員工消費合作社印製 對於具有任意不同截面形狀之平行共擠出的單絲而言 ’因在單一單絲中L S吸收的結果,可能利用其熱膨脹以 修飾單絲形狀。當使用鬃絲在鬃絲載體中時,末端可以藉 雷射輻射而發泡,以改良其在鬃絲載體上之固著。 藉添加不同程度的吸收L S添加劑或藉添加不同濃度 之L S吸收添加劑至個別的單絲,可能有利地影響且控制 上述特徵。 -8 - 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 591134 A7 ____B7__ 五、發明說明έ ) 依本發明,在擠出期間,添加L S吸收添加劑,而在 同時,在單絲使用期間,此添加劑完成進一步之技術功肯g 。爲代替此,除了添加L S吸收添加劑之外,亦可能添加 '具有此一技術功能之添加劑。 在具有一另外技術功能之添加劑的情況中,它們可以 是由不同材料製之磨蝕體,其在一般擠出作用下常具有不 恰當之粘合而進入聚合物中且藉隨後雷射處理會在磨蝕體 附近有局部熔融過程以致進行更堅固之粘合。然而,亦可 能添加在隨後雷射處理時會液化或氣化之物體。 依本發明之用雷射光束之處理可以在拉伸之前及/或 之後及/或在安定之後。單絲在採用雷射光束之後特別可 被安定。 I---------------訂--------- (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 -9 - 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐)
