)至 3 0 0 °F ( 1 4 9 °C ),其中值得地約 2 7 0 °F ( 1 3 5 1C ) 至2 8 5 Τ' ( 1 4 1 1C ),之習用結構的黏合滾筒(即刻槽滾筒與 平滑滾筒),將第二層22熱黏合。以熱黏合滾筒來黏合層 22的適當溫度可因黏合滾筒的旋轉表面速度及直徑以及所 使用之熱塑性纖維來變動。第二層也可藉其他黏合處理來 黏合,例如:式樣膠黏劑黏合,針剌,或水力及氣流纏結 第一層12被黏合至第二層22上的程度可藉著改變黏合 區之百分比而由分離黏合區來控制,黏合區百分比係指各 自層物界面間的表面積被黏合區内之黏合所佔的面積。因 此,如圖1及2所示者,第一層12及第二層22的界面20具 有橫過其表面之分離黏合式樣18,並且界面20之總表面積 上被黏合區18所佔的表面面積為界面20的黏合區百分比。 本紙張又度適用中國國家標準(CNS)甲4规格(210 X 297公釐)

上。於此方式中,當二層物經過處理成形時,第一層12可 作為第二層22的基底基層。 或者,也可將第二層22送過一對輕度密集化纖雒織物 的密集化滾筒而增加織物之整體性並可有助於其他處理。 第二層亦可被送過可使織物中磁維定位以最佳化該材料於 機械方向(MD)及橫切方向(CD)之強度的設備。此處所謂之 機械方向(MD)係指織物被放下的方向(圖3中為左至右)

<3)黏合滾筒間的軋辊壓; ⑷黏合滾筒的直徑; ©被利用於形成層1 2及2 2之材料種類。 亦即,改變上述一或更多之因子有影響其他因子的傾向。 例如,成形處理之綫速度增加使薄膜層懕物層與黏合滾筒 接觸的時間變短。結果,黏合滾筒的溫度必須增加以獲得 二層物所需黏合程度,以補償綫速度的改變。 如上述者,與二層物黏合有關的重要因子為黏合滾筒 6 0與7 0被維持的溫度。很自然地,每一聚合物的溫度低於 某點將不會産任何黏合,同時,溫度高於另一點時又會熔 化太多薄膜且/或纖維。並且亦觀察到黏合滾筒的溫度能 夠影響所産生之非織層壓物的張力強度及柔軟度。在某範 圍内,很持殊地,較高的溫度將産生具有較高張力強度的 膜層壓物。這很可能是由於此溫度範圍内所1 發生之較高及 較低程度的黏合。亦即,較高的溫度可能形成較高的長絲 間黏合而有利於張力強度並稍微地損害柔軟度。此外,較 高的溫度可能造成較差的膨賴枕狀結構,因為非織層2 2中 的熱塑性纖維産生更多的缁縮而對薄膜層壓材料10的柔軟 度及襯墊威有負面之影鎏。 亦更進一步地觀察到滾筒溫度能夠影锻織物黏合區中 的穿孔。雖然黏合區中所産生的穿孔並非單純地由熱所生 本紙張尺度適用中國國家標準(CNS)甲4规格(210 X 297公釐) ----1;-----I-------r-------裝—----I-玎-------

會明顯地下降,並同時使第二層22中的熱塑性纖維被足夠 地加熱而與第一層12中熱塑性薄膜熱融合在一起。無論如 何,與薄膜層1 2接觸之黏合滾筒的溫度必須低於所用薄膜 材料之熔化點。 其他與二層物之黏合相關並與黏合區中穿孔之成形相 關的因為被操作之黏合滾筒的綫速度。於所示之實施例中 ,滾筒被操作之綫速度約40英呎/分(12米/分)至約328 英呎/分(100米/分)或更多。黏合區中穿孔的成形已 被觀察到可藉由二滾筒間不同的旋轉表面速度來改良。旋 轉表面間速度的差異約4¾至約20%,其中方便地被蓮用者 約52至約15%。也可利用旋轉速度高於其他黏合滾筒之黏 合滾筒。雖未希望被任何待殊之理論所限,一般咸信穿孔 之成形是藉由黏合滾筒在不同速度下被操作所造成的,因 為與熱生之密集化黏合區之黏合滾筒表面相切的剪斷力會 本紙張尺度適用中國國家標準(CNS)甲4规格(210 X 297公釐)
