Fuchs 及 W.Kittelimann 出版,Wiley_ VCH(2000),專題6.5,化學程序381頁)〕。這種方法在 技術上長久以來已不能用,因為利用「粘性」結合劑要將 ® 纖維絮均勻結合’在技術上問題重重,纖維絮的鬆的纖維 容易附著在印刷模板上並在短時妨礙印刷程序。我們可將 ' 纖維絮強力壓縮或加壓呈面狀或點狀加壓,以與這種妨 • 礙作用抗衡’但產生的產品因而很扁平且很少有紡織品特 性,且結合劑很容易穿透。 在德專利DE-A-2914617提到一種方法,用於將糊料 均勻而連續地施到紡織品布的前側面而背側上,依該實施 例’將一片利用梳理(Krempeln,英:carding)製造的纖維 7 1322205 承守、,坐一砑光機(Kalander),並因此作預鞏固 (v〇rverfestigen,英:pre_c〇ns〇lidate)。然後將一種結合劑 刀政液呈圖案狀在該紡織品布面側利用滾壓施到其上,然 後乾燥’且該結合劑起交聯作用。 長時以來,具有調溫性質的不織布係將藉著將不織布 (亦即將用結合劑結合的,機械方式穩定化的紡織品布) 用調溫材料作後處理而製造,這些不織布的彈性與柔軟度_ 受到前一道鞏固步驟的影響―不符所要者。 【發明内容】 本發明係針對上述先前技術著手,其目的在提供一種 具有填充材料的不織布,它除了有高度彈性外,還有高柔 軟度。如此,可以製造具有較佳的貼身性(PaSSf0rm,英: flt)及穿著舒適性的紡織品。 本發明另一目的在提供一種較佳的方法以製造具有填

如此,s玄不織布就容易印刷得多。此外該不織布還得一定 膨鬆體積及彈性。在熱處理時,溫度曲線走勢 (Temperaturprom)要選設成使處理溫度保持在該多成份纖 維的較低熔點或較低軟化點的聚合物熔解溫度或軟化溫度 以下,因此熱處理固然造成鬈縮,但不會造成粘合的作用。 在製造本發明的不織布時,藉著造成鬈縮,而可使印 入的結合點有固定膨鬆的體積及柔軟度,因為利用該鬈曲 的纖維或長絲,在纖維母質(F〇sermatrix)中不會形成緊密 的點。該結合點不需作發泡,但如要的話也可作。 為了達成特別軟而彈性的物品’宜使用含有二度空間 式或三度空間式鬈縮的纖維或長絲的不織布。 Μ赞明使用的纖維絮可由不同纖度範圍的任意纖維 類型構成,例如纖度0.5〜10dtex,且宜〇8〜67&χ,尤 宜1·3〜3.3dtex,該纖維混合物要含有至少5重量%,且宜 ^ 2〇重量%的爆縮纖維或長絲,它們可為異質絲(非均 貝)纖維(HeterofU)、二成份纖維或特別的均質絲(單组分 1322205 絲或對應長絲,其他的纖料為㈣不織布習 用的短纖維或長絲纖維。 依本發明所用的纖絮用不同的絮料形成技術產生。主 要係用梳理㈣ie叫過之乾的集層的纖維絮。也可用依 紡絲不織布程序或料程序的直接纖㈣層技術。 特宜使用者為短纖維構成的纖維絮。 所用纖維絮的纖維的集層方式可為各向同性(1Sotrop) 或沿-優A (偏好)方向(V。咖細ehtung),㈣各向異性 ㈣崎。P)者。該纖維絮可由相同或不同纖度的這類纖維 構成。構成纖維絮的纖維可由大不相同的纖維建構,例如 由均質絲纖維’也可由1GG%雙成份纖維構成或—種雙成 份纖維與均質絲纖維構成的薄片(Verschnitt)構成,也可使 用合成纖維與天然纖維的混合物。 宜使用聚酯均質絲纖維,例如均聚酯纖維丨7dtex/38mm 或3_3 dtex/51mm與聚酯雙成份纖維(如聚酯·側對側-雙成 分纖維)混合使用。也可用聚醯胺纖維(例如由pA66,3d/i5”) 在該混合物中,至少5%比例的異質絲纖維[宜為雙成分纖 維(Bikofaser)]係需要者,且宜至少2〇0/〇。 本發明所用的纖維絮可在不織布的製造條件下依所加 的異質絲纖維的量而定各依該梳理過的纖維絮的朝向 (Orientierung)而定而收縮。但該不織布在繼續的工作步驟 令安定化’且宜呈很少收縮方式,例如沿機器方向·3〇〇/〇, 沿棋方向-1.5%。 典型的方式,該使用之纖維絮的單位面積重量為 11 1322205 15〜210克/平方米。 特且使用單位面積密度35〜14〇克/平方米之梳理過的 纖維絮。 纖維材料的例子的聚烯 烯,、♦物、聚酯、聚醯胺或聚丙烯腈以及天然纖維,特 別是纖維素纖維、棉纖維、羊毛或其混合物。 3有該微細粒子的填充材料的結合劑,可為任何性 質一要匕旎在所選的面積範圍中使纖維絮鞏固即可。 …結合劑的例子有化學方式交聯的塑膠,特別是呈分散 液形式者,例如由1右 n &乂聯基團#乙基及丁基丙稀嗖 酉日構成的混合物。作也可佬 性聚合物。A作用二:二顆粒的填充材料的熱塑 掌的處理範圍Γ,且用此方式使在該纖維 子為聚烯Μ的纖”固。這類熱塑性塑膠結合劑的例 範=c:㈣乙稀或聚_ 的/、聚酯粉末。結合劑的例子在us M668G1、w〇_a_G2/12 6()7、w〇 - 〇2/95,3i4 可找到。 ,914 及 W〇-A_ 所用之填充材料可為任何細顆粒, 不織布可以造成所要性質即心 ”要匕們加到 填充材料的粒子為具有„及收或吸附 乂換劑、礦物性填充劑、補強材料、導電 、離子 /粒子。特別是潛熱儲存材料。 5導‘、,、的材料 特且使用者為會膨脹的微封囊、活性 金屬粒子、由超 成的粒子、 及力收材枓或短纖維構成的粒子。 12 1322205 用之物質,其例及 所用之特佳的潛熱儲存材科 可在前述文獻令找到。 為習 特且使用者為微封囊的煙, 作潛熱儲存材料。 ^是用微封囊的石蠟當 潛熱儲存材料的例子示於τ
