疊層無紡布材料焊接原理

疊層無紡布材料焊接原理

超聲波焊接無紡材料

無紡材料由單根纖維或連續長絲（無限長的纖維）組成，形成松散的內聚。具有熱塑性成分的無紡材料（熱成型塑料）可以使用超聲波焊接。材料的塑料部分通過超聲波加熱和熔化，無紡材料可以在沒有膠水的情況下相互連接（焊接）。

適用範圍

无添加剂的无纺材料接合是卫生领域、医疗技术以及化妆品和护理産品的理想选择。超声波焊接用于：

分離和遺漏的邊緣區域（例如一次性清洗手套）

引入壓花結構（例如化妝棉）

爲卷料打孔（例如過濾器材料）

將不同層層壓在一起（例如尿布）

無紡布焊接方式

疊層

由于旋转式底座的结构，与纵向焊缝相比，无纺材料在疊層过程中的接合只能有选择地进行。这具有以下优点，即由于许多目标连接而保留了材料特性。比如过滤功能不受影响，材料保持弹性。

焊接/橫向焊縫

無紡材料也可以使用橫向焊縫焊接。與縱向焊縫一樣，焊頭在固定位置工作，無需上下移動。旋轉式底座使之不同。它確保無紡材料在正確的位置與焊頭接觸，並且只在那裏橫向焊接。例如用于尿布的側縫。

切割

超聲波工具甚至可以切割。同時，切割邊緣被密封。例如，用于生産一次性清洗手套。

穿孔

無紡材料也可以按規定的方式穿孔。材料可以用超聲波和底模輥輕輕穿孔，例如用于傷口敷料和膏藥。

壓花

壓花时，无纺材料，例如化妆棉，刻有特殊结构。一个底模辊对此负责。被连接材料颜色不同时的特点：下面板的颜色在焊缝处可见。设计效果，例如用于徽标-无需额外的彩色印刷。

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
